technical field

The present invention relates to a system for interconnecting wireline and wireless telephone services, and more particularly, to a method for interoperating wireline and wireless telephone services in which mobility is provided for subscribers using wireline telephone services.

Background technique

Generally, traditional public communication networks can be divided into wired telephone service networks and mobile communication telephone service networks. Wired telephone services are provided through the Public Switched Telephone Network (PSTN), and wired telephone terminals are connected to telephone exchanges using telephone lines. In the case of the above-mentioned wired telephone service, it is impossible to provide portability because a wired telephone terminal is connected to a telephone exchange using a telephone line. Of course, even if a wireless phone that communicates wirelessly with the main body of a wired phone terminal using a wireless bandwidth of 900MHZ (megahertz) is being used, there is a large limit to its mobility compared with a mobile communication terminal that uses mobile communication services The problem.

On the other hand, mobility is provided for mobile communication services using Public Land Mobile Networks (hereinafter referred to as PLMNs).

The PLMN includes: a mobile switching center (hereinafter referred to as MSC), which is responsible for mobile communication services in any area; a base station controller (hereinafter referred to as BSC); a base station transceiver subsystem (hereinafter referred to as BTS); and HLR /VLR (Home Location Register/Visitor Location Register). In general, CDMA (Code Division Multiple Access) means a wireless environment responsible for mobile communication services in another area.

The MSC performs connection and control with other MSCs in the PSTN or PLMN for multiple BSCs connected to the MSC.

The BSC performs radio link control and handover functions, and the BTS performs functions of constructing a wireless communication path together with its communication service area, ie, including wireless terminals in its cell area and managing radio resources.

In HLR/VLR, HLR performs user location registration and database function for storing user information, while VLR is a database for temporarily storing information of MSs existing in a cell area charged by corresponding MSC among multiple MSCs . When the MS moves to a cell area managed by other MSC, the information stored in the corresponding VLR is deleted.

Even in the case of a mobile communication telephone service using PLMN, the mobile communication telephone service does not operate interconnectedly with wired telephone terminals using a public switched telephone network, so that there arises a problem that each service operates independently without mutual relationship.

On the other hand, even if a mobile communication service can generally be provided anywhere and is not limited to an area such as a house, the service can be provided only through a mobile communication service system and there is no specific registration in the established area. The tent cannot provide wireless communication.

That is, in order for a wired telephone service terminal utilizing wired telephone service to communicate with a mobile communication terminal of a mobile communication service user, a method is used in which each terminal is connected to the PSTN through each exchange and calls are connected to other terminal.

Here, PSTN includes PLMN and PSTN, and therefore, there is a disadvantage in that a bill is required even when a wired communication user and a mobile communication service user communicate in the same building or complex.

Furthermore, in the case of simultaneously providing wired telephone and mobile communication services to users, there is a difficulty that communication service charges are a heavy burden because users have to pay for each communication.

In addition, in the case where wired telephone and mobile communication services are provided to the user at the same time, and the other party knows one of the two telephone numbers and makes a call to the corresponding terminal, there is a disadvantage in that when the user cannot respond to the call with the corresponding terminal , even if the user owns another terminal, the communication connection cannot be realized.

Of course, when a call is made to any terminal, the call termination service can be used to transfer the call to another terminal. However, there is a problem that the service can be provided when the call has been established in advance, and when the service is allocated, only the terminal to which the call terminating service is allocated is called.

Detailed ways

Referring now to the accompanying drawings, FIG. 1 is a conceptual diagram for explaining a wired telephone service and a mobile communication telephone service in the art. Referring to FIG. 1, a public switched telephone network (PSTN) 10 is used to provide wired telephone service, and a wired telephone terminal 80 is connected to a telephone exchange 70 using a telephone line.

In the case of the above-mentioned wired telephone service, since the wired telephone terminal 80 is connected to the telephone exchange 70 using a telephone line, mobility cannot be provided.

Of course, even if a wireless phone that communicates wirelessly with the main body of a wired phone terminal using a wireless bandwidth of 900 MHz is used, there is a problem that its mobility is greatly restricted compared with a mobile communication terminal using mobile communication services.

On the other hand, mobility is provided for mobile communication services using a public land mobile network (hereinafter referred to as "PLMN").

PLMN includes: Mobile Switching Center (hereinafter referred to as "MSC") 30, MSC is responsible for mobile communication services in any area; Base Station Controller (hereinafter referred to as "BSC") 40; Base Transceiver Subsystem (hereinafter referred to as "BTS") 50; and HLR/VLR (Home Location Register/Visitor Location Register) (not shown). In the figure, CDMA 20 collectively represents a wireless environment responsible for mobile communication services in another area.

The MSC 30 performs connection and control of a plurality of BSCs 40 connected to the MSC 30 with other MSCs (not shown) in the PSTN 10 or PLMN 20.

The BSC 40 performs radio link control and handover functions, and the BTS 50 performs functions of constructing a wireless communication path together with its communication service area, that is, including the wireless terminal 60 in its cell area and managing radio resources.

In the HLR/VLR (not shown), the HLR performs a subscriber location registration function and a database for storing subscriber information, and the VLR is used to temporarily store the MSs present in the sub-district in charge of a corresponding MSC among a plurality of MSCs. database of information. When the MS moves to a cell area managed by other MSC, the information stored in the corresponding VLR is deleted.

Even in the case of a mobile communication telephone service using PLMN, the mobile communication service does not perform interconnection operations with the wired telephone terminal 80 using the public switched telephone network 10, thereby causing a problem that each service operates independently and has no mutual relationship .

The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, the invention may be embodied in various ways and should not be construed as limited to the illustrated embodiments. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Throughout the specification, like numerals refer to like components.

Here, a mobile phone utilizing a mobile communication network represents a concept opposite to a wired telephone service terminal utilizing a wired telephone service, and a mobile telephone is used as a wireless telephone for convenience. Therefore, the term "wireless terminal" is defined as a mobile phone.

FIG. 2 is a network block diagram for explaining the concept of a system for interconnecting wired telephone and wireless telephone services according to an embodiment of the present invention.

With reference to Fig. 2, the system for interconnecting wired telephone and wireless telephone service according to the embodiment of the present invention includes: wired and wireless interconnection equipment 100, described equipment 100 is connected with PSTN 10 and BSC 40 of public mobile communication network, and Wired telephone service and public/private mobile communication service are provided to subscribers registered for the service; a private BTS (hereinafter referred to as "pBTS") 210, connected to the wired and wireless interconnection device 100, and a dedicated mobile communication service within its communication range Communication services provide a wireless environment; wireless terminals 220, 240, and 260 for providing public/private mobile communication services through the pBTS 210, and wired telephone service terminals 230, 250, and 270 for receiving wired telephone services.

The wired and wireless interconnection device 100 provides wired telephone services for the wired telephone service terminals 230, 250 and 270 connected to the device 100 through telephone lines, and provides wired telephone services for the wireless terminals 220, 240 and 270 registered in the dedicated mobile communication service through the pBTS 210. 260 provides public/private mobile communication services. Of course, the public mobile communication service is also provided to regular wireless terminals (not shown) not registered in the private mobile communication service. It also performs wireline and wireless interconnection services for interconnecting wireline and wireless telephone services.

The wired and wireless interconnection device 100 includes the functionality of a wireline telephone exchange that performs wireline telephone services. That is, the device 100 includes a switching device (not shown) to provide wireline telephone service, so that a user registered for the wireline Wired telephone service terminals 230, 250 and 270 in the office are connected to telephone lines to provide wired telephone service.

For example, wired telephone service corresponds to conventional wired telephone service, which is provided by Korea Telecom Group to users through telephone exchanges, and also includes various additional services of Internet services, such as basic outgoing and incoming services.

In addition, the wired telephone service corresponds to the xDSL (x Digital Subscriber Line) subscriber circuit service which has suddenly become popular recently.

Therefore, suitably, the wired and wireless interconnection device 100 may be embodied by interconnecting with a traditional switch installed in a telephone exchange, embodied by improving a switch installed in a telephone exchange, or in a private exchange with a private exchange implemented in the network.

The wired telephone service terminal capable of providing wired telephone service by the wired and wireless interconnection device 100 may be conventional wired telephones 230 and 250, and may correspond to a personal computer 270 and various home network devices (not shown). Conventional wired phones 230 and 250 may include a main body connected by a phone line and utilize a mobile terminal having a frequency of 800 MHz (megahertz).

On the other hand, the wired and wireless interconnection device 100 operates a dedicated mobile communication network in the limited communication area 200 .

Here, the dedicated mobile communication network means a mobile communication service that provides high-quality service to its users within a limited area in which base stations of the limited area can be supported by installing a limited number of base stations in any area , which is generally used for the purpose of distinguishing it from mobile communication networks operated nationwide by different mobile communication service providers (eg, 01X in Korea).

Therefore, any exchange provider and mobile communication device provider can interconnectively provide such services. In addition, service providers who have existing wired telephone networks (eg, KTC in Korea) can also install mobile communication equipment and implement such services.

In order to perform the above-mentioned services, the wired and wireless interconnection device 100 includes a device (not shown) for mobile communication service, and assigns a mobile identification number (MIN) (for example, 02-CCC) to a user registered for the mobile communication telephone service -DDDD), and provide mobile communication telephone service to wireless terminals 230, 250 and 270 located in its dedicated communication area through pBTS 210.

Of course, since the wireless terminals 230, 250, and 270 registered in the mobile communication service of the wired and wireless interconnection device 100 are registered in the service of the public mobile communication network and provided with the mobile communication service using the conventional public mobile communication network, So the terminal is assigned an individual mobile communication terminal telephone number (MIN) (for example, 016-AAA-BBBB).

At this time, the individual phone number assigned by the wired and wireless interconnection device 100 to the mobile terminal registered in the mobile communication service uses the format of the wired phone number (for example, 02-CCC-DDDD). The reason for using the wireline telephone number format for separate telephone numbers is that when an external user using the wireline telephone service makes a call to the corresponding user through the PSTN 10, the external user will be considered a regular wireline telephone service subscriber. Thus, external users can make calls to corresponding users as if they were calling regular wireline telephone service subscribers, and the charges (or prices) are adjusted as if they were calling regular wireline telephone service subscribers. Therefore, such phone numbers are called virtual phone numbers. The virtual phone number is a phone number whose format is that of a conventional wired phone number, it is not a phone number connected to any wired phone terminal through a phone line, but is generated in a software solution in the wired and wireless interconnection device 100 telephone number.

Accordingly, wired and wireless interconnected device 100 may generally have three types of users.

First, there is a type of subscriber who only uses wireline telephone service. Such a user is to be given an arbitrary wired telephone number from the wired and wireless interconnection device 100, and uses the wired telephone service by connecting a wired terminal to a telephone line installed in his/her home.

Second, there is a user who only uses mobile communication services. Such users are simultaneously registered in the public mobile communication network. Therefore, the user has two phone numbers. One is a phone number assigned in the public mobile communication network, and the other is a phone number assigned in the wired and wireless interconnection device 100 . The wired and wireless interconnection device 100 stores information on phone numbers assigned to corresponding users by the device 100 and phone numbers assigned by mobile communication service providers.

Finally, there is a user who uses both wired telephone service and mobile communication service. At this time, the user is given an arbitrary wired telephone number from the wired and wireless interconnection device 100, and uses the wired telephone service by connecting the wired terminal to the telephone line installed in his/her home, and also uses the wired terminal to use mobile communication Serve. Therefore, the user has three phone numbers. One of them is the wired telephone number assigned in the wired terminal, another number is the telephone number assigned to the wireless terminal in the public mobile communication network, and yet another number is assigned to the wireless terminal in the wired and wireless interconnection device 100 virtual phone number. Therefore, the wired and wireless interconnection device 100 stores the information of the three phone numbers of the corresponding users in the database.

The wired and wireless interconnection device 100 can provide differentiated services for each user.

Outgoing/incoming services are provided by regular wireline telephone service over the telephone line to subscribers using only regular wireline telephone service.

When a wireless terminal requests an outgoing call to a user who only uses mobile communication services, when the call ID (identification) based on the MIN (016-AAA-BBBB) assigned only to public mobile communication comes in from the corresponding wireless terminal , only the MIN is converted to a virtual telephone number (02-CCC-DDDD), and the converted call identification ID is transmitted through the PSTN 10. Therefore, the external user receives caller identification ID information of the virtual phone number for a corresponding call.

The multi-termination function can be provided to subscribers of wired telephone service and mobile communication service. The multi-termination function is a function in which a ring signal is simultaneously transmitted to a wired telephone service terminal and a wireless terminal.

That is, in the case of calling the wired telephone service terminal (02-XXX-YYYY) from the outside, a ringing signal is transmitted to the wired telephone terminal corresponding to the wired telephone number through the telephone line, and the search is registered in the terminal with the corresponding wired telephone. The virtual phone number in the user of the phone number, and calls the corresponding wireless terminal through pBTS 210. In addition, in the case where there is no response from the corresponding wireless terminal even though the corresponding wireless terminal has been called through the pBTS 210, it is determined that the corresponding wireless terminal is not in the dedicated communication area, and the public mobile communication network is used to communicate through the public mobile communication network. The BTS 50 of the network calls the corresponding wireless terminal.

In this case, the wired and wireless interconnection device 100 must have a database for each telephone number. For example, device 100 must have a database for storing: information whether multi-termination functionality is established for any telephone number, a virtual telephone number for each corresponding wired telephone number if multi-termination functionality is established, and public mobile phone numbers. A virtual telephone number for each telephone number of the communication network.

When there is a call connection request from any extension user to an extension user or an external user, or a call is made to an extension user from any external user, a corresponding call connection service can be performed.

That is, when the wireless terminals 220, 240 and 260 are registered in the wired and wireless interconnection device 100 to receive mobile communication services, the wired and wireless interconnection device 100 provides the wireless terminals 220, 240 and 260 through the pBTS 210 mobile communication services.

The wired and wireless interconnection device 100 performs wired communication services with the PSTN 10. As an example, when a wireless terminal registered in the wired and wireless interconnection device 100 wishes to communicate with a wireless terminal (not shown) not registered in the wired and wireless interconnection device 100, the wired and wireless interconnection device 100 Connect to the public mobile communication network via PSTN 10, and establish a communication path to the corresponding wireless terminal to make a call.

When the wireless terminals 220, 240 and 260 registered for the service wish to communicate with the public network user 11 instead of the extension line user, the wired and wireless interconnection device 100 establishes a communication path to the public network user through the PSTN 10 to communicate.

On the other hand, when the wireless terminals 220, 240, and 260 registered to use the dedicated mobile communication service in the wired and wireless interconnection device 100 within the communication area of the pBTS 210 (hereinafter referred to as the mobile area) request wireless communication path establishment , the pBTS 210 constructs a wireless communication path and manages wireless resources in order to provide public/private mobile communication services.

In addition, for wireless terminals not registered in the dedicated service, public mobile communication services are provided through the public mobile communication network.

In addition, through the wired and wireless interconnection service device 100, wireless terminals 220, 240, and 260 are provided with other wireless terminals 220, 240, and 260 registered to use dedicated mobile communication services, or with wired telephone service terminals 230, 250, and 270. call service.

That is, in the case where the wireless terminals 220, 240 and 260 registered to use the mobile communication service in the wired and wireless interconnection device 100 request wireless communication path establishment, the pBTS 210 establishes a wireless communication path to make a call, while not in the wired The pBTS 210 can use the public mobile communication network through the BSC 40 when a wireless terminal (not shown) registered to use a dedicated mobile communication service in the wireless interconnection device 100 requests wireless communication path establishment.

For the service operation of the system for interconnecting wired and wireless constructed as described above, the following processing is required.

First, a user registration application for wired and wireless services is received from an arbitrary extension user. The information requested when applying for user registration may include the user's personal affairs information, settlement information, the telephone number of the wired terminal, the individual telephone number of the mobile communication terminal, and the virtual wired telephone number of the mobile communication terminal. Here, personal transactional information includes name, address and identification number.

According to the user registration application, one or more wired terminals and public/private mobile communication terminals are assigned wired telephone numbers, and wired and wireless service registration is performed in each extension user.

When registering wired and wireless services, processing is performed in which, as extension user information, wired telephone numbers assigned to wired terminals constituting an extension network, wired telephone numbers assigned to public/private mobile communication terminals, and The Mobile Identifier Number (MIN) assigned to public/private mobile communication terminals in the public mobile communication network.

Next, a process is performed. In this process, the first identification information for indicating whether any wired telephone number is a wired telephone number connected to the terminal is registered in the database, indicating whether the wired telephone number uses the simultaneous termination service. The second identification information, and the wired telephone number of the public/private mobile communication terminal called by the simultaneous termination function. After the registration process is completed, if any wired telephone number is called, the wired terminal corresponding to the corresponding wired telephone number is called and interconnected to the wired telephone number, so that when there are public/private mobile communication terminals called at the same time , call the corresponding public/private mobile communication terminal through the mobile communication network. Processing for charging by wired and wireless services in each extension user can be performed. In the case of using a dedicated mobile communication network when charging is performed, an extension charging rate may be applied, and in the case of using a public mobile communication network, an outside line charging rate may be applied.

FIG. 3 is a system block diagram explaining the concept of a system for interconnecting wired and wireless telephone services according to the embodiment shown in FIG. 2. Referring to FIG.

Referring to FIG. 3, the wired and wireless interconnection device 100 includes a wired switch 111, a mobile gateway 112 and a pBSC 113.

The wireline switch 111 is a switching system that provides services to the wireline telephone network, while the mobile gateway 112 is a system for handling calls made among wireline and wireless users. The pBSC 113 connects the mobile gateway 112 to the pBTS 210, and is also connected to the BSC 40 of the public mobile communication network for conventional public mobile communication services.

This embodiment is wherein the mobile gateway 112 is used as a switch interconnected to the wired switch 111, and the PSTN 10 is defined by the CCIT (International Telegraph and Telephone Consultative Committee) through NO.7 signaling (NO.7 signaling system) Common channel signaling system) is connected to the trunk line of the wired exchange 111.

In the wired exchange 111, the extension Subscriber Line Card (SLC) interface passes E1 signaling (E1 is the European standard for digital lines of 2.048 Mbit/s containing 32 time slots, another example is T1, which is 24 channels 1.544 Mbit/s digital signal level 1 (DS1), and T3 (DS3), which is digital signal level 3 working at 44.736 Mbit/s, are connected to the trunk line of the mobile gateway 112 .

That is to say, in the case that the wired exchange 111 assigns a wired telephone number to any user of the wired telephone service, the exchange 111 does not directly connect the SLC interface allocated with the wired telephone number to the wired telephone terminal 250 of the user through a telephone line, but first The SLC interface is connected to the trunk line of the mobile gateway 112 before it is transmitted to the mobile gateway 112 .

The mobile gateway 112 assigns the extension subscriber line of the wired telephone service of the wired exchange 111 received through the trunk line to its SLC interface, and connects the line with the corresponding wired telephone terminal 250 through the telephone line.

Therefore, the wired telephone terminal 250 is connected to the SLC interface of the wired switch 111 via the SLC interface of the mobile gateway 112 and the trunk line. Therefore, the wired telephone terminal 250 can hear the dial tone provided by the wired telephone exchange 111 when the user takes off the handset to talk.

In addition, when the exchange 111 provides wired telephone service to its extension users, the wired exchange 111 can assign a wired telephone number to each user within the range that the SLC interface can provide. Wireline switch 111 may include a database (included in memory) that includes the wireline telephone number assigned to each extension user.

Here, the wired telephone number may be a commonly used number whose end is connected to the wired telephone terminal 250; and a virtual telephone number whose end is not connected to the wired telephone terminal 250 and in which only a telephone number is allocated.

However, in the wired exchange 111, there is no distinction between regular wired phone numbers and virtual phone numbers. This is because the wired exchange 111 distributes the telephone number for any extension user to the SLC (Subscriber Line Card) interface, and transmits it to the trunk line of the mobile gateway 112 through the SLC interface, and whether the wired telephone terminal 250 is connected to the mobile gateway 112 when its role ends The end connection of the assigned telephone number depends on the mobile gateway 112, and in the same way, the extension user information is used to control the wire switch 111.

The mobile gateway 112 is connected with the pBSC 113 through E1 signaling, and is used to interconnect the wired telephone service of the wired exchange 111 with the mobile communication service of the pBSC 113.

That is to say, the circuit allocated by connecting the mobile gateway 112 to the pBSC 113 through E1 signaling is related to the wireless terminal.

The mobile gateway 112 has a database 112b (such as included in the memory 112a) for the wired telephone numbers assigned by the wired switch 111 . That is, the database stores information indicating whether each telephone number is a virtual telephone number, and information indicating whether each telephone number is registered in the multi-terminal service as shown in FIG. 4 .

For example, when the field indicating whether it is a virtual telephone number is set up with 0, it indicates that the telephone number is a wired telephone number connected to a wired terminal, and the field is filled with 1, which indicates that the telephone number is a virtual telephone number.

On the other hand, when the field indicating whether multi-termination is performed is filled with 0, it indicates that the service is limited to the existing service for making calls to the wired telephone terminal corresponding to the corresponding wired telephone number, and when indicating whether multi-terminated When the field of is filled with 1, it means that the service is registered in the multi-terminated service.

Therefore, when making a call to any wired telephone number registered in the multi-terminal service, since detailed information about the virtual wired telephone number corresponding to the wireless terminal simultaneously called with the wired telephone number is required, the mobile gateway 112 sends the pBSC 113 requests this information.

When receiving the virtual telephone number information about the wireless terminal connected to the corresponding wired telephone number from pBSC 113, after searching for the corresponding virtual telephone number in its database, call the corresponding virtual telephone number by pBSC 113 and pBTS 210 Corresponding wireless terminal.

On the other hand, when the mobile gateway 112 receives an outgoing service request from any terminal through the pBSC 113, the mobile gateway 112 transmits the outgoing call number received from the corresponding wireless terminal and the caller ID of the mobile terminal to the wired exchange 111.

At this time, the caller ID of the wired terminal transmitted to the wired switch 111 becomes a virtual wired telephone number (for example, 02-CCC-DDDD) given to the wireless terminal. Accordingly, the wired switch 111 transmits its caller ID and makes a call to the user of the corresponding outgoing number.

Here, the user of the outgoing call can be an internal user of the wired exchange 111, and can also be an external user who can call through the PSTN 10.

The pBSC 113 performs functions corresponding to the BSC in the public mobile communication system, that is, performs mobile link control and handover.

The pBSC 113 controls the pBTS 210 to perform call processing for users supporting public mobile communication network and private mobile communication network services, and analyze additional services, and handle all types of interfaces for interconnection to the mobile gateway 112.

For this reason, when receiving a dedicated mobile communication service, a wireless terminal user adds pre-established identification information to an outgoing call number in order to distinguish the service.

Therefore, the pBSC 113 uses the identification information to distinguish whether the outgoing call requires a public mobile communication service or a dedicated mobile communication service.

That is to say, it is determined whether the outgoing call of the wireless terminal transmitted from the pBTS 210 is an outgoing call requesting a public mobile communication service or an outgoing call requesting a dedicated mobile communication service, and whether it is an outgoing call requesting a public mobile communication service , the outgoing call is transparently bypassed to the BSC 40 of the public mobile communication network, and when the call is a dedicated mobile communication service outgoing call, the outgoing call is transferred to the mobile gateway 112 to provide the dedicated mobile communication service .

For example, when the user enters the telephone number "#211" through the wireless terminal, since it includes the identifier "#" indicating that the user wishes to use the dedicated mobile communication service, it is determined that the pBSC 113 wishes to use the dedicated mobile communication service, and will include the telephone number The call request signal of "212" is sent to the mobile gateway 112, and the extension user of "212" can be talked with.

When the user inputs the telephone number "#02-212-8866", since the number includes the identifier "#" indicating that the user wishes to use the dedicated mobile communication service, pBSC 113 determines that the user wishes to use the dedicated mobile communication service, and pBSC 113 sends A call request signal including the telephone number "02-212-8866" is sent to the mobile gateway 112, and a call can be made with the public telephone network user "02-212-8866" through the public telephone network using the wired exchange 111.

When the user inputs the telephone number "#016-212-8866", since the number includes the identifier "#" indicating that the user wishes to use the dedicated mobile communication service, pBSC 113 determines that the user wishes to use the dedicated mobile communication service, and pBSC 113 sends A call request signal including the phone number "016-212-8866" is sent to the mobile gateway 112, and a call can be made with the public mobile communication service user "016-212-8866" via the public mobile communication network via the public telephone network using the wired exchange 111 . Other identifiers than "#" can also be used.

pBSC 113 includes the MIN number (for example, 016-AAA-BBBB) that has been allocated in any wireless terminal by the public mobile communication network, and the virtual wired telephone number (for example, 02-CCC) for the wireless terminal as shown in Figure 5 - DDDD) database 113b (such as included in memory 113a).

That is, the database 113b stores information indicating whether a virtual wired number exists in each MIN number of an arbitrary wireless terminal, and stores the wired number information if a corresponding virtual wired number exists.

For example, when the field indicating whether there is a virtual wired number is set up by 0, it means that there is no virtual wired number; when the field is set up by 1, it means that there is a virtual wired number corresponding to the MIN number, and the Corresponding virtual wired number.

Therefore, even if a call is made to the virtual wired telephone number in the mobile gateway 112, the corresponding wireless terminal can be called.

On the other hand, when any wireless terminal requests an outbound service through the pBTS 210, it can be roughly divided into two situations.

First, there may be a case where an outgoing call is requested using a dedicated mobile communication service. In this case, since the MIN number assigned to the public mobile communication network is transmitted by using the caller ID transmitted from pBTS 210, the caller ID is converted into a virtual wired telephone with reference to the database 113b as shown in FIG. 5 number, and send out through the mobile gateway 112 and the wired switch 111.

In the case of not using the dedicated mobile communication service, since the MIN number assigned to the public mobile communication network is transmitted using the caller ID transmitted from the pBTS 210, the caller ID is transmitted to the BSC 40 of the public mobile communication network as it is.

In addition, pBSC 113 manages a multi-termination service database 113c (such as included in memory 113). That is, the pBSC 113 manages the wired telephone numbers (for example, 02-XXX-YYYY) established for its multi-termination function in the wired telephone terminals installed at home, and the wireless terminals are simultaneously assigned when calling the corresponding wired telephone numbers. database 113c of virtual wired telephone numbers.

Therefore, in the case where the mobile gateway 112 inquires about the virtual wired telephone number established multiple times for the wired telephone number (for example, 02-XXX-YYYY) registered in the multi-terminal service, by searching the corresponding wired telephone number ( For example, 02-XXX-YYYY) finds a virtual phone number (02-CCC-DDDD) associated with the landline phone number, and the mobile gateway 112 can respond.

That is, databases (112b and 113c) are built in each of the mobile gateway 112 and the pBSC for multi-termination services. A database 112b built in mobile gateway 112 (eg, included in memory 112a) stores information on whether any wireline telephone number is multi-terminated, and a virtual wireline telephone number assigned to each wireless terminal.

On the other hand, the database 113c constructed in the pBSC 113 (e.g., included in the memory 113a) stores information about any wired telephone number in which the multi-termination function is established, and about wireless terminals called in the multi-termination of the wired telephone number. Information about virtual wired phone numbers. Databases 113c and 113b may also be a single database.

In the wired and wireless interconnection device 100 constructed as described above, not only wired telephone service for wired telephone terminals can be performed, but also calls can be terminated to assigned wired terminals when performing virtual wired telephones.

Additionally, when a call is made to a wired phone, both wired and wireless calls can be made in the mobile gateway 112 simultaneously and the call terminated to the desired terminal.

In the case of making a call to a virtual wired phone in the PSTN 10, the wired switch 111 makes a call to the mobile gateway 112. The mobile gateway 112 makes a call to the wireless terminal in the mobile area 200 through the pBSC 113 and the pBTS 210 corresponding to the virtual wired telephone number.

When the terminating response comes from the wireless terminal, the call is connected. When a terminating response does not come, the service is terminated according to wireline service processing.

FIG. 6 is a diagram showing a process of making a call to a corresponding wired phone or a wireless phone when a call is made to a wired phone in the system for interconnecting wired and wireless phone services shown in FIG. 3 .

Termination processing will be explained with reference to the termination paths (P1, P2) shown in FIG.

Under the situation that any user terminal 11 calls any wired telephone number by PSTN 10, call corresponding wired telephone number (S1) to wired switchboard 111 by PSTN 10, and determine whether called telephone number is wired subscriber number (S2) . As a result of the determination, if the called telephone number is a wired subscriber number, it is transmitted to the mobile gateway 112 through the wired subscriber circuit (S3). On the other hand, if it is not the wired subscriber number as a result of the determination, a virtual subscriber circuit allocated to the wireless terminal is selected and transmitted to the mobile gateway 112 (S4).

The mobile gateway 112 analyzes the telephone number transmitted from the wired switch 111 . First, the mobile gateway 112 determines whether the corresponding telephone number in the database 112b owned by the gateway 112 shown in FIG. 4 is a multi-terminal number (S5). As a result of the determination, in case it is not a multi-termination number, the call is distributed to the wired subscriber (S6). Thereafter, the wired terminal 250 responds to the assignment (S7).

On the other hand, if, as a result of the determination, the corresponding number is a multi-termination number, the call is first distributed to the wired subscriber (S8) (P1). Also, a request is made to the pBSC 113 for the virtual wired telephone number assigned to the corresponding wired number (S9). The reason why the mobile gateway 112 requests the virtual wired telephone number from the pBSC 113 is that the database 112b of the mobile gateway 112 stores only information indicating whether the multi-termination of any wired terminal is established.

Since the pBSC 113 stores direct information for the corresponding wireless terminals that have multi-terminated for the wired number, the mobile gateway 112 requests from the mobile gateway 112 the virtual wire telephone number corresponding to the wireless terminal multi-terminated to the pBSC 113.

Accordingly, the pBSC 113 searches its database for a virtual number for the corresponding wired telephone number and provides the mobile gateway 112 with the virtual number. The mobile gateway 112 distributes the call to the corresponding wireless terminal (S10) (P2) through the pBSC 113 and pBTS 210). Thus, one of the wired terminal 250 and the wireless terminal 220 responds to the allocation (S11). Furthermore, when the wireless terminal does not respond to the allocation, the wireless terminal can be provisioned to the terminating service anywhere in the mobility area 200 .

On the other hand, when determining whether the called telephone number is a wired subscriber number (S2), when the called telephone number is not a wired subscriber number, when the virtual subscriber circuit assigned to the wireless terminal is selected and the circuit is communicated to the mobile gateway After 112 (S4), the mobile gateway 112 distributes the call to the corresponding wireless terminal through the pBSC 113 and the pBTS 210 (S12). Accordingly, the corresponding wireless terminal 220 responds to the allocation (S13).

Fig. 7 is a diagram showing the processing of a wireless terminal user calling an external user, Fig. 8 is a diagram showing the processing of a wireless terminal user calling an internal user, and Fig. 9 is a diagram showing a wireless terminal user calling an external user or an internal user Flowchart of a user making a call.

The termination process of FIG. 9 is explained with reference to the termination path ( P3 ) of FIG. 7 and the termination path ( P4 ) of FIG. 8 .

The wireless terminal 220 (for example, 016-AAA-BBBB) makes a call to the other party's number (for example, 031-ZZZ-ZZZZ, or 02-XXX-XXXX) (S21). An outgoing call generated in the wireless terminal 220 is transmitted to the mobile gateway 112 through the pBTS 210 and the pBSC 113 (S22).

At this time, the pBSC 112 changes the caller ID (016-AAA-BBBB) given to the wireless terminal to a virtual wired number (for example, 02-CCC-DDDD) (S23). At this time, the change of the caller ID is performed with reference to the database shown in FIG. 5 .

The mobile gateway 112 determines whether the outgoing call number issued from the wireless terminal is an external outgoing call number (S24). When it is an external outgoing number, the call is stored in a message and transmitted to the wired exchange 111 (S25). The wired exchange 111 makes a call (P3) to the external user of the corresponding telephone number through the PSTN 10 (S26).

On the other hand, when the mobile gateway 112 determines whether the outgoing call number sent from the wireless terminal is an external outgoing call number (S24), it is determined that the outgoing call number is not an external outgoing call number, and the internal users 220, 240 and 260 in the mobile area 200 are called (P4)(S27).

At this time, charging processing may be performed through a charging device (not shown) connected to the wired switch 111 . Here, calls between internal users within the wired and wireless interconnection device 100 within the mobile area 200 are not subject to special charges and can run free of charge. In this case, internal users can talk to each other without being charged for the call.

10 and 11 are diagrams showing the processing of incoming call rerouting when there is nothing in the mobile area (that is, there is no user in the mobile area 200, and there is no response from a wired terminal or a wireless terminal in the mobile area 200). diagram.

The rerouting process of FIG. 11 will be explained with reference to the terminating paths (P5, P6, and P7A) in FIG. 10 .

When any external user 11 calls any wired telephone number by PSTN 10, call the corresponding wired telephone number to wired switchboard 111 by PSTN 10, and determine whether the called telephone number is a wired subscriber number (S31). As a result of the determination, if the called telephone number is a wired subscriber number, it is transmitted to the mobile gateway 112 through the wired subscriber circuit (S32). On the other hand, if the called telephone number is not a wired subscriber number as a result of the determination, a virtual subscriber circuit allocated to the wireless terminal is selected and transmitted to the mobile gateway 112 (S33).

The mobile gateway 112 analyzes the telephone number transmitted from the wired switch 111 . At this time, the mobile gateway 112 has the database 112b shown in FIG. 4 . The mobile gateway 112 determines whether the corresponding phone number in the database is a multi-terminal number (S34). As a result of the determination, in the case that the corresponding telephone number is not a multi-termination number, since this is a case of calling only to a wired telephone terminal, the call is distributed to a wired subscriber (S35). On the other hand, as a result of the determination in S34, in the case that the corresponding telephone number is a multi-termination number, the call is first distributed to the wired subscriber (S36). Next, the mobile gateway 112 requests the virtual number from the pBSC 113, and provides the virtual number of the corresponding wired telephone number from the pBSC 113, and distributes the call to the corresponding wireless terminal 220 through the pBSC 113 and the BTS 210 (S37). On the other hand, in the case that the mobile gateway 112 receives the wired telephone number through the virtual subscriber circuit assigned to the wireless terminal, then the mobile gateway 112 distributes the call to the corresponding wireless terminal 220 through the pBSC 113 and the BTS 210.

Next, if at least one of the wired terminal 250 and the wireless terminal 220 responds in the mobile area 200, the call is processed according to the response, otherwise, it is determined whether there is a user in the mobile area 200 (S38). In the case that there is no user in the mobile area 200 due to the absence of wired terminals and wireless terminal responses in the mobile area 200, the mobile gateway 112 passes through the public mobile communication network via the wired switch 111 and the PSTN 10 and the CDMA network 20. The BTS 50 makes a call to the wireless terminal 50a in the public mobile communication network. On the other hand, in the case where there is no response even though there is a user in the mobile area 200, a voice information message such as "Please call again because the user is unavailable now" may be transmitted (S40).

second embodiment

FIG. 12 is a system block diagram explaining a system concept for interconnecting wireline and wireless telephone services according to another embodiment of the wireline and wireless interconnection device shown in FIG. 2 .

Referring to FIG. 12 , the wired and wireless interconnection device 100 includes a wired switch 121, a mobile gateway 122, and a pBSC 123.

Since the mobile area 200 including the pBTS 210 in the drawings has been explained above, its explanation can be omitted here.

This embodiment is an example in which the mobile gateway 122 is used as a tandem (Tandem) switch, and the PSTN 10 is connected to the trunk line of the mobile gateway 122 through No. 7 signaling.

The wired exchange 121 is a system that provides services of the wired telephone network to users other than the mobile area 200 , and the mobile gateway 122 is a system for handling calls made for wired and wireless users in the mobile area 200 .

That is to say, the mobile gateway performs call processing of the wired telephone network service and the mobile communication service to the wired and wireless users 220 and 270 in the mobile area 200, and the wired switch 121 is to wire users (not shown) except the mobile area 200. Shown) A system for providing wireline telephone service.

For example, in the case of installing a telephone exchange for a large-scale complex apartment, there are wired and wireless subscribers living in the complex apartment located in the mobile area 200 where the pBTS 210 is installed and mobile communication services can be provided by the pBTS 210, and those located in the non-installed The pBTS 210 and therefore cannot provide mobile communication services but only the wired telephone service subscribers in the complex outside the mobile area 200 that can provide regular wired telephone services.

In the case of a large complex apartment, as the number of users increases, there are cases where it is not allowed to provide wired telephones to users within the mobile area 200 and users outside the mobile area 200 in one mobile gateway 122 due to the capacity of the exchange. Serve.

Therefore, in the case that the wired and wireless telephone users are in the mobile area 200, the corresponding communication service is provided by the mobile gateway 122, and when the user is outside the mobile area 200, the corresponding communication service is provided by the separate wired switch 121 Serve.

Thus, in the event that there is a call to any wired telephone number through the PSTN 10, the mobile gateway 122 determines whether the telephone number is an incoming call for its extension user. In addition, as a result of determination, in the case that the telephone number is not an extension incoming call, for example, the subscriber telephone number is outside the mobile area 200, the call is a tandem (Tandem) call, and the call is transferred to the wired exchange 121, and then Corresponding services are provided in the wired switch 121 .

The pBSC 123 connects the mobile gateway 122 with the pBTS 210, and is also connected with the BSC 40 of the public mobile communication network for conventional mobile communication services.

That is, when the mobile gateway 122 allocates a wired telephone number to any user of the wired telephone service, it directly connects the SLC interface assigned the wired telephone number to the wired telephone terminal 250 through a telephone line. Therefore, when the wired telephone terminal 250 takes off the handset to talk, the wired telephone terminal 250 hears the dial tone provided in the mobile gateway 122 .

In addition, when mobile gateway 122 provides wireline telephone service to its extension users, each user may be assigned a wireline telephone number to the extent that the SLC interface can provide.

Here, the wired telephone number may be a regular telephone number whose end is connected to the wired telephone terminal 250, and may also be a virtual wired telephone number not connected to the wired telephone terminal 250 and only assigned a telephone number.

On the other hand, the mobile gateway 122 is connected with the pBSC 123 through E1 signaling, and performs the function of interconnecting with the pBSC 123 mobile communication service.

To this end, the mobile gateway 122 has a database 122b (eg, included in memory 122a) for wireline telephone numbers. That is, this database 122b stores information indicating whether each telephone number is a virtual telephone number, and whether each telephone number has been registered in the multi-terminal service.

For example, when the field indicating whether each phone number is a virtual phone is established with 0, it means that the phone number is a wired phone number connected to a wired terminal; when the field is filled with 1, it means that the phone number is a wireless phone number The virtual phone number of the terminal.

On the other hand, when the field indicating whether the multi-termination service is established is filled with 0, it means that the service is limited to the existing service for making calls to the wired terminal corresponding to the corresponding wired telephone number; and when the field is filled with 1 , which indicates that the service is registered with Services that can perform multi-terminated services.

Therefore, in the case of calling any wired telephone number registered with the multi-terminal service, since the detailed information of the virtual wired telephone number corresponding to the wireless terminal to be called simultaneously with the wired telephone number is required, the mobile gateway 122 This information is requested from pBSC 123.

When the information about the virtual phone number of the wireless terminal connected with the corresponding wired phone number is received from pBSC 123, the corresponding virtual phone number is found in its database, and the pair of pBSC 123 and pBST 210 corresponds to its virtual phone number wireless terminal to make a call.

On the other hand, when the mobile gateway 122 receives an outgoing service request from any terminal through the pBSC 123, the mobile gateway 122 transmits the outgoing number and the caller ID of the wireless terminal received from the corresponding wireless terminal, and calls the user of the corresponding outgoing number Make a call.

At this time, the caller ID of the wireless terminal transmitted to the mobile gateway 122 becomes the virtual wired telephone number (for example, 02-CCC-DDDD) assigned to the wireless terminal.

Here, the user of the outgoing call can be an internal user of the mobile gateway 122 and an external user who can make a call through the PSTN 10.

The pBSC 123 performs functions corresponding to the BSC in the public mobile communication system, that is, performs radio link control and handover.

The pBSC 123 controls the pBTS 210 to perform user's call processing to support public mobile communication network and private mobile communication network services, and analyze additional services, and handle all kinds of interfaces for interconnection to the mobile gateway 122.

For this reason, in the case of receiving dedicated mobile communication services, wireless terminal users add pre-established identification information to outgoing phone numbers to distinguish these services.

Therefore, pBSC 123 uses this identification information to distinguish whether the outgoing call requires public mobile communication services or private mobile communication services.

That is, it is determined whether the outgoing call of the wireless terminal transmitted from the pBTS 210 is an outgoing call requesting a public mobile communication service or an outgoing call requesting a dedicated mobile communication service, and, when the outgoing call is a public mobile communication service When making a call, the outgoing call is transparently bypassed to the BSC 40 of the public mobile communication network, and when the outgoing call is an outgoing call for a dedicated mobile communication service, the outgoing call is transmitted to the mobile gateway 122 to provide a private mobile communication service. mobile communication services.

For example, when the user enters the phone number "#212" through the wireless terminal, since it includes "#" indicating that the user wishes to use the dedicated mobile communication service, it is determined that pBSC123 wants to use the dedicated mobile communication service, and will include the phone number The call request signal of "212" is transmitted to the mobile gateway 122, and the call can be made with the extension user "212".

When the user inputs the telephone number "#02-212-8866", since the number includes "#" indicating that the user wishes to use the dedicated mobile communication service, the pBSC 123 determines that the user wishes to use the dedicated mobile communication service, and the pBSC 123 The call request signal including the phone number "02-212-8866" is transmitted to the mobile gateway 122, and a call can be made with the public telephone network user "02-212-8866" through the PSTN 10.

When the user enters the telephone number "#016-212-8866", due to the "#" of the identifier indicating that the user wishes to use the dedicated mobile communication service, the pBSC 123 determines that the user wishes to use the dedicated mobile communication service, and the pBSC 123 will include the telephone The call request signal of the number "016-212-8866" is transmitted to the mobile gateway 122, and the call can be made with the public mobile communication service user "016-212-8866" via the PSTN 10 through the public mobile communication network. Identifiers other than "#" can also be used.

pBSC 123 includes: the MIN number (for example, 016-AAA-BBBB) that the public mobile communication network has assigned to any wireless terminal, and the virtual wired telephone number (such as 02-CCC) for the assigned wireless terminal as shown in Figure 5 - DDDD) database 123b (such as included in memory 123a).

That is, the database stores information indicating whether or not a virtual wired number exists in each MIN number of an arbitrary wireless terminal, and its wired number information if there is a corresponding virtual wired number.

For example, when the field indicating whether there is a virtual wired number is set up by 0, it means that there is no virtual wired number; and when the field is set up by 1, it means that there is a virtual wired number corresponding to the MIN number, and stored with The corresponding virtual wired number.

Therefore, even in the case of a call to the virtual wired telephone number in the mobile gateway 122, the corresponding wireless terminal can be called.

On the other hand, when any wireless terminal requests an outgoing call service through the pBTS 210, it is roughly divided into two situations.

First, there is a case where an outgoing call is requested using a dedicated mobile communication service. In this case, when using the caller ID transmitted from pBTS 210 to load the MIN number assigned to the public mobile communication network, refer to the database 123b as shown in Figure 5 to convert the caller ID into a virtual wired telephone number, And send it to the mobile gateway 122.

When the caller ID transmitted from the pBTS 210 is used to transmit the MIN number assigned to the public mobile communication network without using the dedicated mobile communication service, the caller ID is transmitted to the BSC 40 of the public mobile communication network as it is.

In addition, pBSC 123 manages a multi-termination service database 123c (e.g., included in memory 123a). That is, the pBSC 113 manages the wired telephone numbers (for example, 02-XXX-YYYY) established for its multi-termination function in the wired telephone terminals installed at home, and the virtual telephone numbers given to the wireless terminals at the same time when the corresponding wired telephone numbers are called. Database 113c of wired telephone numbers. It is also possible to combine database 123c into database 123b.

Therefore, in the case where the mobile gateway 112 inquires about the virtual wired telephone number established multiple times for the wired telephone number (for example, 02-XXX-YYYY) registered in the multi-terminal service, by searching the corresponding wired telephone number ( For example, 02-XXX-YYYY) finds a virtual phone number (02-CCC-DDDD) associated with the landline phone number, and the mobile gateway 112 can respond.

That is, databases (122b and 123c) are constructed in each of the mobile gateway 122 and pBSC 123 for multi-termination services. The database 122b constructed in the mobile gateway 122 stores information on whether any wire telephone number is multi-terminated, and a virtual wire telephone number assigned to each wireless terminal.

On the other hand, the database 123c constructed in the pBSC 123 stores information on any wired telephone number in which the multi-termination function is established, and the virtual wired telephone number of the wireless terminal to be called in the multi-termination of the wired telephone number.

In the wired and wireless interconnection device 100 constructed as described above, not only wired telephone service can be performed for a wired telephone terminal, but also a call can be terminated to an assigned wired terminal when a call is made to a virtual wired telephone. In addition, when a call is made to a wired phone, it is possible to simultaneously make a wired and wireless call in the mobile gateway 122 and terminate the call to a desired terminal.

In the case of making a call to the virtual wired phone in the PSTN 10, the mobile gateway 122 calls the wireless terminal in the calling mobile area 200 through the pBSC 123 and pBTS 210 corresponding to the virtual wired phone number.

When the incoming call response is from the wireless terminal, the call is connected. When the incoming call response does not come, the service is ended according to the wired telephone service processing.

13 and 14 are diagrams showing a process of simultaneously calling a wired telephone and a wireless terminal when a wired telephone is called.

Incoming call processing will be explained with reference to the incoming call path (P7B, P8) shown in FIG. 13 and the flowchart shown in FIG.

In the case that any user terminal 11 calls any wired telephone number through the PSTN 10, the mobile gateway 122 receives the corresponding wired telephone number through the PSTN 10, and determines whether the called telephone number is an incoming call of an extension user in the mobile gateway 122 number (S101). As a result of the determination, in the case that the called telephone number is not an extension incoming call, it is a tandem call and transferred to the wired exchange 121 (S102). On the other hand, in the case that the called telephone number is an extension incoming call, the mobile gateway 122 analyzes the telephone number transmitted from the PSTN 10. At this time, the mobile gateway 122 identifies whether the corresponding phone number is a wired phone number and whether the corresponding phone number is a multi-terminal number through the database 122b shown in FIG. 4 .

First, it is determined whether the corresponding telephone number is a wired subscriber telephone number (S103). Where the corresponding telephone number is not a wireline subscriber telephone number, the telephone number is a wireless subscriber telephone number and thus a virtual number is requested from pBSC 123 and provided by pBSC 123. In addition, the call is distributed to the corresponding wireless terminal 220 through the pBSC 123 and the pBTS 210 (S104). Then, the corresponding wireless terminal 220 responds to the assignment (S105).

On the other hand, as a result of the determination in step S103, in a case where the corresponding telephone number is a wired subscriber telephone number, it is determined whether the subscriber telephone number is a telephone number established for wired and wireless multi-termination (S106). As a determined result of step S106, in the case where the subscriber's telephone number is not a multi-terminated number, the call is distributed to the wired subscriber (S107). Accordingly, the wired terminal 250 responds to the assignment (S108). However, in the case of a multi-terminated number, the call is first distributed to a wired subscriber (S109). In addition, a virtual number is requested to the pBSC 123 and provided from the pBSC 123, and then the call is distributed to the corresponding wireless terminal 220 through the pBSC 123 and the pBTS 210 (S110). Then, one of the wired terminal 250 and the wireless terminal 220 responds to the assignment accordingly (S111).

Fig. 15 is a diagram showing the processing of a wireless terminal user making a call to an external user, Fig. 16 is a diagram showing the processing of a wireless terminal user making a call to an internal user, and Fig. 17 is a diagram showing a wireless terminal user making a call to an external user A flow diagram of processing by a user or internal user.

The incoming call processing of FIG. 17 will be explained with reference to the incoming call path P9 of FIG. 15 and the incoming call path P10 of FIG. 16 .

A call is made to the other party's number (for example, 031-ZZZ-ZZZZ or 02-XXX-XXXX) in the wireless terminal 220 (for example, 016-AAA-BBBB) (S121). An outgoing call generated in the wireless terminal 220 is transmitted to the mobile gateway 122 through the pBTS 210 and the pBSC 123 (S122).

At this time, the pBSC 123 changes the caller ID (016-AAA-BBBB) given to the wireless terminal to a virtual wired number (for example, 02-CCC-DDDD) given to the wireless terminal (S123).

The mobile gateway 122 determines whether the outgoing call number transmitted from the wireless terminal is an external outgoing call number (S124). As a result of the determination of S124, in the case of an external outgoing call number, a call is made to the external user of the corresponding telephone number through the PSTN 10 (S125).

On the other hand, when it is determined in the mobile gateway 122 whether the outgoing number is an external outgoing number, in the case that the outgoing number is not an external outgoing number as a result of the judgment, a call is made to the internal users 220, 240, and 260 in the mobile area 200 (P10)(S126).

At this time, billing processing is performed with a billing device (not shown) connected to the Tandem mobile gateway 122 .

Here, calls between internal users performed in the wired and wireless interconnection device 100 in the mobile area 200 may not be charged but may be operated free of charge. In this case, users can make calls between internal users without separate charges.

18 and 19 are diagrams showing a process of rerouting an incoming call when there is nothing in the mobile area.

The rerouting process of FIG. 19 will be explained with reference to the incoming call paths P11, P12, and P13 of FIG.

In the case that any user terminal 11 calls any wired telephone number through the PSTN 10, the mobile gateway 122 receives the corresponding wired telephone number through the PSTN 10, and determines whether the called telephone number is an incoming call of an extension user in the mobile gateway 122 number (S131). As a result of judgment in S131, in the case that the called telephone number is not an extension incoming call number, then the called telephone number is a tandem (Tandem) calling number, and is transmitted to the wired exchange (S132).

On the other hand, in the case that the called telephone number is an extension incoming call, the mobile gateway 122 analyzes the telephone number transmitted from the PSTN 10. At this time, the mobile gateway 122 identifies whether the corresponding phone number is a wired phone number and whether the corresponding phone number is a multi-terminal number through its database.

First, it is determined whether the corresponding phone number is a wired phone number (S133). As a result of the determination, in the case of the wired subscriber number, it is determined whether the wired subscriber number is a telephone number established for wired and wireless multi-termination (S134). As a result of the determination, in the case that the wired subscriber number is not a multi-terminated number, the call is distributed only to the wired subscriber and this state is maintained until a response to the state is made in the corresponding wired terminal (S135). On the other hand, as a result of the determination, in the case of a multi-terminated number, the call is first distributed to the wired subscriber (S136). In addition, a virtual number is requested to the pBSC 123 and provided from the pBSC 123, and then the call is distributed to the corresponding wireless terminal 220 through the pBSC 123 and the pBTS 210 (S137). Incidentally, in case the mobile gateway 122 receives the wired telephone number through the virtual subscriber circuit assigned to the wireless terminal, it distributes the call to the corresponding wireless terminal 220 through the pBSC 123 and the pBTS 210.

Next, in the case where at least one of the wired terminal 250 and the wireless terminal 220 in the mobile area 200 responds to the state, the call is processed according to the response. In case of no response, it is determined whether there is a user in the mobile area 200 (S138). Under the situation of determining that there is no user in the mobile area 200 due to the absence of a wired terminal 250 or a response from the wireless terminal 220 in the mobile area 200, the mobile gateway 122 utilizes the PSTN 10 and the CDMA network 20 to pass through the BTS 50 existing in the public mobile communication network , make a call to the wireless terminal 50a in the public mobile communication network (S139). In case there is no response even though the user exists in the mobile area 200, a voice information message such as "please call again because the user is unavailable now" may be transmitted (S140).

third embodiment

FIG. 20 is a system block diagram explaining the concept of a system for interconnecting wired and wireless telephone services according to another embodiment of the wired and wireless interconnection device shown in FIG. 2 .

Referring to FIG. 20, the wired and wireless interconnection device 100 includes a group switch 131 and a dedicated base station controller pBSC 132 for performing wired switching functions and mobile gateway functions.

Since the mobile region 200 including the pBTS 210 in the drawing was explained earlier, its explanation can be omitted.

The group group exchange 131 is a system that performs call processing for the wired telephone network and mobile communication services to wired and wireless users 220 to 270 in the mobile area 200, and to users (not shown) outside the mobile area 200 Wired telephone service is available.

For example, in the case of installing a switchboard in a small complex apartment, install pBTS 210, and provide wired and wireless telephone interconnection service to wired and wireless subscribers living in the apartment located in the mobile area 200 provided by pBTS 210 for wireless service, And provide conventional wired telephone service to the wired telephone service subscriber who lives in the apartment located outside the mobile area 200 provided by BTS 210 for mobile communication service.

The pBSC 132 connects the group switch 131 with the pBTS 210, and is also connected with the BSC 40 of the public mobile communication network for conventional public mobile communication services.

In this embodiment, the functions of a mobile gateway and a wired switch are implemented in a group switch 131, wherein the PSTN 10 is connected to the trunk line of the group switch 131 through No. 7 signaling.

The wire switch 111 is connected to each of the wire telephone terminals 230, 250, and 270 through a extension subscriber line card (SLC) interface using a telephone line.

That is to say, when the group switch 131 assigns a wired telephone number to any user of the wired telephone service, the SLC interface assigned the wired telephone number is directly connected to the user's wired telephone terminal 250 through a telephone line. Therefore, when the handset is picked up to talk, the wired telephone terminal 250 hears the dial tone provided by the group switch 131 .

Furthermore, when the group group switch 131 provides wireline telephone service to its extension users, a wireline telephone number is assigned to each user to the extent that the SLC interface can provide it.

Here, the wired telephone number may be a regular telephone number whose end is connected to the wired telephone terminal 250, and may be a virtual wired telephone number not connected to the wired telephone terminal 250 but only a telephone number is assigned.

On the other hand, the group switch 131 is connected with the pBSC 132 through E1 signaling, and performs the function of interconnecting the mobile communication service of the pBSC 132.

To this end, the group switch 131 has a database 131b (such as included in memory 131a) for wired telephone numbers. That is, this database 131b stores information indicating whether each telephone number is a virtual telephone number, and whether each telephone number has been registered in a multi-terminal service, as shown in FIG. 4 .

For example, when the field indicating whether each phone number is a virtual phone is established with 0, it means that the phone number is a wired phone number connected to a wired terminal; and when the field is filled with 1, it means that the phone number is a wireless terminal virtual phone number for .

On the other hand, when the field indicating whether the multi-termination service has been established is filled with 0, it means that the service is limited to the existing service for the wired telephone terminal corresponding to the corresponding wired telephone number; and when the field is filled with 1 , it means that the service is registered in the service that can execute multi-terminal service.

Therefore, in the case of making a call to any wired telephone number registered with the multi-terminal service, since the detailed information of the virtual wired telephone number corresponding to the wireless terminal whose wired telephone number is called at the same time is required, the group group switch 131 sends a call to the pBSC 132 to request the information,

When the information about the virtual telephone number of the wireless terminal connected to the corresponding wired telephone number is received from pBSC 132, the corresponding virtual telephone number is found in its database, and corresponds to the virtual telephone number through the pair of pBSC 132 and pBST 210 wireless terminal to make a call.

On the other hand, when the group group switch 131 transmits the outgoing number and caller ID of the wireless terminal received from the corresponding wireless terminal, and when the user of the corresponding outgoing number is called, the group group switch 131 transfers the call from any terminal through the pBSC 132. Receive outbound service requests.

At this time, the caller ID (identification) of the wireless terminal transmitted to the group group switch 131 becomes the virtual wired telephone number (for example, 02-CCC-DDDD) assigned to the wireless terminal.

Here, the user of the outgoing call can be an internal user of the group switch 131 and an external user who can make a call through the PSTN 10.

The pBSC 132 performs functions corresponding to the BSC in the public mobile communication system, that is, performs radio link control and handover.

The pBSC 132 controls the pBTS 210 to perform user's call processing to support public mobile communication network and private mobile communication network services, and analyze additional services, and handle all kinds of interfaces for interconnecting the group switch 131.

For this reason, in the case where a wireless terminal user wishes to receive dedicated mobile communication services, the user adds pre-established identification information to the outgoing phone number to distinguish these services.

Therefore, pBSC 132 uses this identification information to distinguish whether the outgoing call requires public mobile communication services or private mobile communication services.

That is to say, it is determined whether the outgoing call of the wireless terminal transmitted from the pBTS 210 is an outgoing call requesting a public mobile communication service or an outgoing call requesting a dedicated mobile communication service, when the outgoing call is a public mobile communication service When making a call, the outgoing call is transparently bypassed to the BSC 40 of the public mobile communication network, and when the outgoing call is a dedicated mobile communication service outgoing call, the outgoing call is sent to the group switch 131 for Provide dedicated mobile communication services.

For example, when the user enters the telephone number "#212" through the wireless terminal, since it includes the identifier "#" indicating that the user wishes to use the dedicated mobile communication service, it is determined that pBSC132 wishes to use the dedicated mobile communication service, and will include the telephone number "#" The call request signal of 212" is transmitted to the group exchange 131, and it is possible to talk with the extension user "212".

When the user inputs the telephone number "#02-212-8866", since the number includes the identifier "#" indicating that the user wishes to use the dedicated mobile communication service, the pBSC 132 determines that the user wishes to use the dedicated mobile communication service, and the pBSC 132 will The call request signal including the telephone number "02-212-8866" is transmitted to the group exchange 131, and a call can be made with the public telephone network user "02-212-8866" through the PSTN 10.

When the user inputs the telephone number "#016-212-8866", since the number includes the identifier "#" indicating that the user wishes to use the dedicated mobile communication service, the pBSC 132 determines that the user wishes to use the dedicated mobile communication service, and the pBSC 132 will The call request signal including the phone number "016-212-8866" is transmitted to the group switch 131, and the PSTN 10 can be used to communicate with the public mobile communication service user "016-212-8866" through the public mobile communication network. Identifiers other than "#" can also be used.

pBSC 132 includes: the MIN number (for example, 016-AAA-BBBB) that the public mobile communication network has assigned to any wireless terminal, and the virtual wired telephone number (such as 02-CCC-DDDD) assigned to the wireless terminal as shown in Figure 5 ) database 132b (such as included in memory 132a).

That is, the database stores information indicating whether or not a virtual wired number exists in each MIN number of an arbitrary wireless terminal, and its wired number information if the corresponding virtual wired number exists.

For example, when the field indicating whether there is a virtual wired number is set up by 0, it means that there is no virtual wired number; and when the field is set up by 1, it means that there is a virtual wired number corresponding to the MIN number, and stored with The corresponding virtual wired number.

Therefore, even when a call is made to the virtual wired telephone number in the group switch 131, the corresponding wireless terminal can be called.

On the other hand, when any wireless terminal requests an outbound service through the pBTS 210, it can be roughly divided into two situations.

First, there may be a case where an outgoing call is requested using a dedicated mobile communication service. In this case, when utilizing the caller ID transmitted from the pBTS 210 to transmit the MIN number given to the public mobile communication network, the caller ID is converted into a virtual wired telephone number with reference to the database 132b as shown in FIG. 5 , and send it to the group switch 131.

On the other hand, when the MIN number assigned to the public mobile communication network is transmitted using the calling party ID transmitted from pBTS 210 without using the dedicated mobile communication service, the calling party ID is transmitted as it is to the MIN number of the public mobile communication network. BSc40.

Also, pBSC 132 manages a database 132c (such as included in memory 132a) for multi-termination services. That is to say, the pBSC 132 manages the wired telephone numbers (for example, 02-XXX-YYYY) established for its multi-termination function in the wired telephone terminal installed at home, and assigns the number to be called simultaneously when calling the corresponding wired telephone number. Database 132c of virtual wired telephone numbers of wireless terminals.

Therefore, in the case where the group switch 131 inquires about the virtual wired telephone number established multiple times for the wired telephone number (for example, 02-XXX-YYYY) registered in the multi-terminal service, by searching the corresponding wired telephone number in the database, The number (eg, 02-XXX-YYYY) finds the virtual phone number (02-CCC-DDDD) associated with the wired phone number and can respond to the group switch 131.

That is, databases (131b and 132c) are constructed in each of the group group switch 131 and the pBSC 132 for multi-terminated services. The database 131b constituted in the group switch 131 stores information on whether or not to multi-tap an arbitrary wired telephone number, and a virtual wired telephone number assigned to each wireless terminal.

On the other hand, the database 132c constructed in the pBSC 132 stores information on any wired telephone number in which the multi-termination function is established, and the virtual wired telephone number of the wireless terminal to be called in the multi-termination of the wired telephone number. Database 132c may also be combined into database 132b.

In the wired and wireless interconnection device 100 constructed as described above, not only wired telephone service can be performed for wired telephone terminals, but also a call can be terminated to an assigned wired terminal when a virtual wired telephone is called. In addition, when a wired telephone is called, it is possible to simultaneously make a wired and wireless call in the group switch 131 and terminate the call to a desired terminal.

In the case of making a call to a virtual wired telephone in the PSTN 10, the group switch 131 makes a call to a wireless terminal in the mobile area 200 through the pBSC 132 and pBTS 210 corresponding to the virtual wired telephone number.

When the incoming call response is from the wireless terminal, the call is connected. When the incoming call response does not come, the service is ended according to the wired telephone service processing.

21 and 22 are diagrams showing a process of simultaneously calling a wired telephone and a wireless terminal when a wired telephone is called.

Incoming call processing will be explained with reference to destination paths (P14, P15) as shown in FIG. 21 .

In the case that any user terminal 11 calls any wired telephone number through PSTN 10, the group switch 131 receives the corresponding wired telephone number through PSTN 10 and analyzes the telephone number. At this time, the group switch 131 determines whether the corresponding telephone number is a wired subscriber telephone number (S201). As a determined result of S201, in the case of not being a wired subscriber telephone number, since the corresponding telephone number is a wireless terminal subscriber number, the call is distributed to the corresponding wireless terminal through pBSC132 and pBTS 210. Accordingly, the corresponding wireless terminal 220 responds to the allocation (S203).

On the other hand, when determining whether the called telephone number is a wired subscriber telephone number, as a result of the determination in S201, in the case that the called telephone number is a wired subscriber telephone number, determine whether the corresponding telephone number is The multi-terminal number in the database 131b (S204). In a case where it is determined that the corresponding telephone number is not a multi-termination number as a result of the determination of S204, the call is distributed to the wired subscriber (S205), and the wired terminal responds to the distribution (S206).

However, in the case of a multi-terminated number as a result of the determination at S204, the group group switch 131 first distributes the call to the wired subscriber (S207) (P14). In addition, the virtual number is requested to the pBSC 132 and the searched virtual number is received from the pBSC 132, thereby distributing the call to the corresponding wireless terminal 220 through the pBSC 132 and the pBTS 210 (S208) (P15). Then, one of the wired terminal 250 and the wireless terminal 220 responds to the allocation (S209). Furthermore, when the wireless terminal does not respond to the allocation, the wireless terminal can be provided to the terminating service anywhere in the mobility area 200 .

On the other hand, when determining whether the corresponding telephone number is a wired subscriber telephone number (S201), in the case of not being a wired subscriber telephone number, the call is distributed to the corresponding wireless terminal by pBSC 132 and pBTS 210 (S202), so As described above, the corresponding wireless terminal 220 responds to the assignment (S203).

Fig. 23 is a diagram showing the processing of a wireless terminal user calling an external user, Fig. 24 is a diagram showing the processing of a wireless terminal user calling an internal user, and Fig. 25 is a diagram showing a wireless terminal user calling an external user or an internal user Flowchart of a user making a call.

The termination process of FIG. 25 will be explained with reference to the termination path ( P16 ) of FIG. 23 and the termination path ( P17 ) of FIG. 24 .

The wireless terminal 220 (for example, 016-AAA-BBBB) makes a call to the other party's number (for example, 031-ZZZ-ZZZZ or 02-XXX-XXXX) (S211). The outgoing call generated in the wireless terminal 220 is transferred to the group switch 131 through the pBTS 210 and the pBSC 132 (S212).

At this time, the pBSC 132 changes the caller ID (016-AAA-BBBB) given to the wireless terminal to a virtual wired number (for example, 02-CCC-DDDD) (S213). Here, the change of the caller ID is performed with reference to the database 132b of FIG. 5 .

The group switch 131 determines whether the outgoing call number issued from the wireless terminal is an external outgoing call number (S124). In the case that it is an external outgoing number, the group switch 131 calls the external user of the corresponding telephone number through the PSTN 10 (P16) (S215).

On the other hand, when the group group exchange 131 determines whether the outgoing number sent from the wireless terminal is an external outgoing number, in the case of determining that the outgoing number is not an external outgoing number, the internal users 220, 240 and 260 makes a call (P17) (S216).

At this time, billing processing is performed by a billing device (not shown) connected to the group switch 131 . Here, calls between internal users performed in the wired and wireless interconnection device 100 within the mobile area 200 may not be charged but may be operated free of charge. In this case, users can talk to each other without being charged for the call.

26 and 27 are diagrams showing a process of rerouting an incoming call when there is nothing in the mobile area.

The rerouting process of FIG. 27 will be explained with reference to the terminating paths ( P18 , P19 and P20 ) of FIG. 26 .

In the case that any user terminal 11 calls any wired telephone number through PSTN 10, the group switch 131 receives the corresponding wired telephone number through PSTN 10 and analyzes the called telephone number. At this time, the group switch 131 determines whether the corresponding wired telephone number is a wired subscriber number (S221). As a result of the determination, in the case of a wired subscriber telephone number, the group group exchange 131 determines whether its corresponding telephone number in the database 131b as shown in FIG. 4 is a multi-terminal number (S222). As a result of the determination of S222, in the case that the corresponding telephone number is not a multi-terminated number, the call is distributed to the wired subscriber (S223). However, as a result of the determination of S222, in the case that the corresponding telephone number is a multi-terminated number, the call is first distributed to the wired subscriber (P18) (S224). Next, the group switch 131 requests the virtual number to the pBSC 132, and provides the virtual number of the corresponding wired telephone number from the pBSC 132, and the call is distributed to the corresponding wireless terminal 220 by the pBSC 132 and the pBTS 210 (P19) (S225 ). On the other hand, when it is determined whether the corresponding telephone number is a wired subscriber number (S221), in the case of not a wired subscriber telephone number as a result of the determination, the call is distributed to the corresponding wireless terminal through the pBSC 132 and pBTS 210.

Next, in case at least one of the wired terminal 250 and the wireless terminal 220 in the mobile area 200 responds, the call is processed according to the response, otherwise, it is determined whether there is a user in the mobile area 200 (S226). Because there is no wired terminal or wireless terminal response in the mobile area 200 and there is a user in the mobile area 200, and there is nothing in the mobile area 200, the group switch 131 utilizes the PSTN 10 and the CDMA network 20 to pass through the public mobile communication network. The BTS 50 existing in the public mobile communication network calls the wireless terminal 50a (S227). In case of no response even when there is a user in the mobile area 200, a voice information message such as "please call again because the user is unavailable now" may be transmitted (S228).

Effect

According to the present invention, in the case where a user subscribes a user in a wired telephone service using a wired and wireless interconnection device, portability is provided in the wired telephone service, wherein, when calling a wired telephone terminal, it is possible to pass an existing Wired telephony services and distributed wireless terminals that simultaneously terminate calls in a dedicated mobile communications network operated by wired and wireless interconnected equipment.

In addition, when operating a virtual wired telephone number in the form of a conventional wired telephone service telephone number, it is possible to receive a telephone call by an external user using the wired telephone number through the user's wireless terminal, and since the calling party is The ID is transmitted as a virtual wired telephone number, and it is possible to obtain an effect that the user has a wired telephone terminal in the view of an external user in a state where the wired telephone terminal is not installed. In addition, when an external user makes a call to the user's wireless terminal, telephone service can be provided at the billing rate of the wired telephone service.

In addition, even when a user uses wired telephone and wireless telephone services at the same time, the internal user can not be charged, so that the burden due to double charging can be reduced.
