Description

The present invention relates to a wired / wireless telephone linked service system, and more particularly, to a wired / wireless telephone linked service operation method for providing mobility to a subscriber using a wired telephone service.

In general, a conventional public communication network can be divided into a wired telephone service and a mobile communication telephone service.

FIG. 1 is a conceptual diagram illustrating a conventional wired telephone service and a mobile communication telephone service. Referring to FIG. 1, a wired telephone service is connected from a telephone station (70) to a wired telephone terminal (80) via a telephone line using a public telephone network (PSTN) (10).

As described above, in the case of the wired telephone service, there is no mobility because the telephone station (70) is connected to the wired telephone terminal (80) via the telephone line.

Of course, a wireless telephone that performs wireless communication using such a wired telephone terminal body and a 900 MHz wireless band has been developed and used. However, there are many restrictions on mobility as compared with a mobile communication terminal using a mobile communication service. There is a problem to be received.

On the other hand, in the mobile communication telephone service, mobility is provided by using a public land mobile network (PLMN).

The PLMN includes a mobile switching center (MSC) (30) in charge of mobile communication services in an arbitrary area, a base station controller (BSC) (40), and a base station (BTS: Base Station Transceiver Subsystem (50) and HLR / VLR (Home Location Register / Visitor Location Register) (not shown). In the drawing, CDMA (20) generally indicates a wireless environment in charge of a mobile communication service in another area.

The MSC (30) controls connection of a plurality of BSCs (40) connected to itself to a PSTN (Public Switch Telephone Network) (10) or another MSC (not shown) in the PLMN (20).

The BSC (40) performs a radio link control, a handoff function, and the like, and the BTS (50) configures a radio communication path together with radio terminals belonging to its own communication service area, that is, its own cell area, and Perform the function of managing

In the HLR / VLR (not shown), the HLR performs a subscriber location registration function and a database function for storing subscriber information, and the VLR exists in a cell area assigned to a corresponding MSC among a plurality of MSCs and the like. This is a database for temporarily storing information on the MS to be executed. If the MS moves to a cell area managed by another MSC, the information stored in the corresponding VLR is deleted.

As described above, even in the case of the mobile communication telephone service using the PLMN, the services are independent of each other and are not interconnected with the wired telephone terminal (80) using the public telephone network (PSTN) (10). There is no problem.

On the other hand, in general, mobile communication services can be provided anywhere, irrespective of limited areas such as premises, but this uses a mobile communication service system, and there is no separate charge in the set area. Could not communicate wirelessly.

That is, in order for a wired telephone service terminal using a wired telephone service to communicate with a mobile communication terminal of a mobile communication service subscriber, each exchange is connected via a public network, and then a call is connected to a partner terminal. there were.

Here, the public network includes a PLMN and a PSTN. As a result, there is an inconvenience that a wired subscriber and a mobile communication service subscriber are charged even if they make a call in the same building or the same apartment complex.

Further, when a certain subscriber is provided with a wired telephone service and a mobile communication service at the same time, there is a disadvantage that the use of the communication service becomes excessively burdensome because the respective communication fees should be paid.

Also, when a subscriber is provided with a wired telephone service and a mobile communication service at the same time, if another person only knows one of the telephone numbers and calls the corresponding terminal, if that terminal cannot answer, Despite the fact that the subscriber has another terminal, there is a disadvantage that the call cannot be connected with the subscriber.

Of course, if there is a call to any terminal using the call diversion service, the designated other terminal can be called, but this is only available if it is set in advance. However, if the call diversion service is set, there is a problem that only the terminal designated as the call diversion is called out of the two terminals.

Accordingly, the present invention has been devised to solve the above problems, and an object of the present invention is to provide a method for operating a wired / wireless telephone interlocking service for providing mobility to a conventional wired telephone service subscriber. There is.

Another object of the present invention is to provide a method of operating a wired / wireless telephone interlocking service that can reduce a burden associated with dual charging when a certain subscriber uses a wired telephone service and a mobile communication service at the same time. There is a purpose.

Another object of the present invention is to provide a system in which a subscriber uses a wired telephone service and a mobile communication service at the same time, and the subscriber has a call to one of the telephone numbers. It is an object of the present invention to provide a method of operating a wired / wireless telephone-linked service that enables any terminal to answer a call.

According to one aspect of the present invention to achieve the above object, a step of receiving a subscriber registration application for a wired / wireless service from any extension subscriber, and at least one or more wired terminals and the like by the subscriber registration application And performing wire / wireless service registration for each extension subscriber by assigning a wired telephone number to a public / private mobile communication terminal, etc., and when an arbitrary wired telephone number is called, the wired terminal corresponding to the wired telephone number And calling a corresponding public / private mobile communication terminal via a mobile communication network if there is a public / private mobile communication terminal that is simultaneously called in conjunction with a wired telephone number, and using a wired / wireless service for each extension subscriber And a method for operating a wired / wireless telephone interlocked service, the method comprising:

According to the present invention, when a subscriber subscribes to a wired telephone service by a wired / wireless interlocking device, not only an existing wired telephone service but also a call to a corresponding wired telephone terminal can be made available via a designated wireless terminal. The ability to simultaneously receive calls within a private mobile communication network operated by a wireless interworking device provides mobility to a wired telephone service.

In addition, by operating a virtual wired telephone number in the form of a general wired telephone service telephone number, an external subscriber can receive a telephone call with a wired telephone number through his / her own wireless terminal. At the time of calling, the caller ID is sent as a virtual wired telephone number, so that even if the subscriber actually does not have a wired telephone terminal installed, the same effect as if the external subscriber had a wired telephone terminal Can be provided. In addition, when an external subscriber or the like calls the wireless terminal of the subscriber, the telephone service can be received at a charging rate of the wired telephone service.

Further, even when a certain subscriber uses the wired telephone service and the mobile communication service at the same time, there is a possibility that the internal subscriber is not charged, so that the burden on the dual charging can be reduced.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, a mobile communication terminal using a mobile communication network is a concept corresponding to a wired telephone service terminal using a wired telephone service, and for convenience, the term wireless terminal is used. Therefore, the wireless terminal here is limited to a mobile communication terminal.

FIG. 2 is a network configuration diagram for explaining the concept of the wired / wireless telephone link service system according to one embodiment of the present invention.

Referring to FIG. 2, a wired / wireless telephone link service system according to an embodiment of the present invention is connected to a public telephone network (10) and a base station controller (40) of a public mobile communication network and registered as a service. A wired / wireless interlocking device (100) for providing a wired telephone service and a public / private mobile communication service to a subscriber, and a private / mobile interlocking device (100) connected to the wired / wireless interlocking device (100) for a private mobile communication service within its own communication area. A private base station device (private BTS, hereinafter referred to as pBTS) (210) for providing a wireless environment and a wireless terminal (220, 240, 260) provided with a public / private mobile communication service via the pBTS (210) And a wired telephone service terminal (230, 250, 270) provided with a wired telephone service.

The wired / wireless interlocking device (100) provides a wired telephone service to wired telephone service terminals (230, 250, 270) connected through a telephone line, and a wireless terminal (220, 220) registered to use a private mobile communication service. 240, 260) to provide public / private mobile communication services via pBTS (210). Of course, the public mobile communication service is also provided to general wireless terminals (not shown) not registered in the private mobile communication service. In addition, a wired / wireless link service for linking a wired telephone service and a mobile communication service is provided.

The wired / wireless interlocking device (100) includes a function of a wired telephone station that performs a wired telephone service. That is, an individual telephone number (for example, 02-XXX-YYYY) is assigned to a subscriber registered in the wired telephone service with a switching device (not shown) for the wired telephone service, and the subscriber is installed in the subscriber's home. A wired telephone service is provided through a telephone line connected to the wired telephone service terminals (230, 250, 270).

The wired telephone service is, for example, a general wired telephone service provided to a subscriber via a telephone office in Korean communication, and includes various additional services such as an Internet service including a basic calling service and a receiving service. Can be applicable.

Also, the xDSL subscriber line service that has been rapidly spreading recently can be applicable.

Accordingly, the wired / wireless interlocking device 100 may be implemented in conjunction with a switch provided in a conventional telephone station, and may be implemented by improving the switch provided in the telephone station. It can also be embodied in a private switching network with a private exchange.

Wired telephone service terminals capable of providing a wired telephone service from the wired / wireless interlocking device (100) include general wired telephones (230, 250), personal computers (270), and various types of home network. Equipment (not shown) or the like may be applicable. The general wired telephones 230 and 250 may include a main body connected via a telephone line and a mobile terminal using 800 MHz radio.

On the other hand, the wired / wireless interworking device (100) operates a private mobile communication network in the restricted communication area (200).

Here, the private mobile communication network is generally used to distinguish it from a public mobile communication network operated nationwide by various mobile communication carriers (for example, 01X service provider in Korea). A mobile communication service in which a limited number of base stations are provided and a high quality service is provided to its subscribers in a limited area that the base station can accept.

Accordingly, in the case of such a service, it can be operated in cooperation with an arbitrary exchange operator and a mobile communication device operator, and an operator having an existing wired telephone network (for example, in the case of Korea, ) Can be realized by providing a mobile communication device.

To this end, the wired / wireless interlocking device (100) includes a device (not shown) for a mobile communication service and provides a subscriber registered in the mobile communication telephone service with an individual telephone number (Mobile Identifier Number: MIN) (for example, MIN). 02-CCC-DDDD) to provide a mobile communication telephone service to a wireless terminal (230, 250, 270) located in its own private communication area via the pBTS (210).

Of course, the wireless terminals (230, 250, 270) registered in the mobile communication service of the wired / wireless interlocking device (100) are registered in the service of the public mobile communication network, and the mobile communication service using the general public mobile communication network is not available. Since the mobile communication service is provided, a separate mobile communication terminal telephone number (MIN) (for example, 016-AAA-BBBB) is given by the mobile communication carrier.

At this time, a wired telephone number format (for example, 02-CCC-DDDD) is used as an individual telephone number assigned to a wireless terminal registered in a mobile communication service by the wired / wireless interlocking device (100). The use of the wired telephone number format is used to recognize an external subscriber using the wired telephone service as a general wired telephone service subscriber when calling the corresponding subscriber via the PSTN (10). Thus, when the external subscriber calls the corresponding subscriber, he or she can call a general wired telephone service subscriber, and the fee is settled at the rate when calling the general wired telephone service subscriber. Therefore, such a telephone number is referred to as a virtual telephone number. The virtual telephone number is a telephone number in the form of a general wired telephone number, which is a telephone number generated only by software in the wired / wireless interlocking device (100). It means a virtual telephone number other than a telephone number connected to a wired telephone terminal.

Therefore, the wired / wireless interlocking device (100) can have three types of subscribers.

First, a subscriber who uses only the wired telephone service. In this case, the subscriber is given an arbitrary wired telephone number from the wired / wireless interlocking device (100), and uses a wired telephone service by connecting a wired terminal to a telephone line provided to the house.

Next is a subscriber who uses only mobile communication services. In this case, the subscriber is also registered with the public mobile communication network. Therefore, in the case of this subscriber, two types of telephone numbers are given. One is a telephone number given by the public mobile communication network, and the other is a telephone number given by the wired / wireless interlocking device (100). The wired / wireless interlocking device (100) stores information on a telephone number assigned to the subscriber and a telephone number assigned by a public mobile communication network operator in a database.

Finally, a subscriber who uses both the wired telephone service and the mobile communication service. In this case, the subscriber is given an arbitrary wired telephone number from the wireless interlocking device (100), connects the wired terminal to a telephone line provided to the house, uses the wired telephone service, and moves using the wireless terminal. A subscriber who also uses communication services. Therefore, in the case of this subscriber, three types of telephone numbers are given. One is a wired telephone number given to a wired telephone terminal, the other is a telephone number given to a wireless terminal in a public mobile communication network, and the other is a wired / wireless interlocking device ( 100) is a virtual telephone number assigned to the wireless terminal. As a result, the wired / wireless interlocking device (100) stores the above three types of telephone number information in the database for the corresponding subscriber.

The wired / wireless interlocking device 100 can provide differentiated services to each subscriber.

A subscriber who uses only a general wire telephone service is provided with an outgoing / incoming call service by a general wire telephone service through a telephone line.

When a subscriber who uses only the mobile communication service has a call request via a wireless terminal, a caller ID (Caller ID) is sent from the wireless terminal to the MIN (016-AAA-BBBB) assigned from the public mobile communication network. As a result, the caller ID is converted to a virtual telephone number (02-CCC-DDDD) and the converted caller ID is transmitted via the PSTN (10). As a result, the external subscriber receives the virtual telephone number as the caller ID information for the call.

A subscriber who uses both the wired telephone service and the mobile communication service can be provided with a multiple reception function. The multiple incoming call function allows a ring signal to be simultaneously transmitted to a wired telephone service terminal and a wireless terminal.

That is, when the telephone number of the wired telephone service terminal (02-XXX-YYYY) is called from outside, a ring signal is transmitted to the wired telephone terminal corresponding to the wired telephone number via the telephone line, and the corresponding wired telephone number is transmitted. Is searched for a virtual telephone number registered in a subscriber having a password, and the corresponding wireless terminal is called via the pBST (210). Also, if there is no response from the wireless terminal in spite of calling the wireless terminal via the pBST (210), it is determined that the terminal is not in the private communication service area, and the public mobile communication network is connected via the public mobile communication network. The corresponding wireless terminal is called via the BTS (50) of the communication network.

In this case, the wired / wireless interlocking device (100) must have a database for each telephone number. For example, if multiple incoming / outgoing is possible and multiple incoming is set for an arbitrary telephone number, there must be a database for the virtual telephone number for the corresponding wired telephone number and the virtual telephone number for the public mobile communication network telephone number. Must.

Also, when there is a call connection request from an extension subscriber to an extension or an external subscriber using this database, or when an extension subscriber is called from an external subscriber, a corresponding call connection service can be performed. .

In other words, if the wireless terminal (220, 240, 260) is registered for use in the wired / wireless interlocking device (100) so that the mobile communication service can be provided, the wired / wireless interlocking device (100) can use the pBTS A mobile communication service is provided to the wireless terminals (220, 240, 260) via (210).

The wired / wireless interlocking device (100) also provides a wired communication service with the PSTN (10). As an example, if the wireless / wireless interlocking device (100) desires to communicate with a wireless terminal (not shown) whose service is registered with the public mobile communication network via the PSTN (10), To establish a communication path with the corresponding wireless terminal so that a call can be made.

If the wired / wireless interlocking device (100) desires that the service-registered wireless terminals (220, 240, 260) talk with the public network subscriber (11) who is not an extension subscriber, the wireless terminal (100) communicates via the PSTN (10). By setting a communication path with a public network subscriber, a call can be made.

On the other hand, the pBTS (210) has a wireless terminal (220, 240) whose use of the private mobile communication service is registered in the wired / wireless interlocking device (100) in its own communication area (hereinafter, referred to as a mobile zone) (200). , 260) request the establishment of a wireless communication path, configure a wireless communication path, and provide public / private mobile communication services by managing wireless resources.

In addition, for a wireless terminal that is not registered in the private mobile communication service, a public mobile communication service is provided via a public mobile communication network.

In addition, the wireless terminal (220, 240, 260) is connected to another wireless terminal (220, 240, 260) registered for use of the private mobile communication service via the wired / wireless interlocking device (100), or a wired telephone service. A call service with the terminals 230, 250, and 270 can be provided.

That is, when a wireless terminal (220, 240, 260) whose mobile communication service is registered for use in the wired / wireless interlocking device (100) requests wireless communication channel setting, the pBTS (210) transmits the wireless communication channel. When a wireless terminal (not shown) that has not registered the use of the private mobile communication service in the wired / wireless interlocking device (100) requests a wireless communication channel setting, the BSC ( 40) to use a public mobile communication network.

The following procedures are required for service operation of the wired / wireless interlocked service system configured as described above.

First, a subscriber registration application for a wired / wireless service is received from an arbitrary extension subscriber. When applying for subscriber registration, the required information may include the subscriber's personal information, payment information, telephone number of wired terminal, individual telephone number of mobile communication terminal, virtual wired telephone number of mobile communication terminal, etc. it can. Here, the personal information may include a name, an address, a resident registration number, and the like.

A wired telephone number is assigned to one or more wired terminals and public / private mobile communication terminals and the like and a wired / wireless service registration is performed for each extension subscriber according to the subscriber registration application.

When registering the wired / wireless service, the wired telephone number assigned to the wired terminal constituting the extension network, the wired telephone number assigned to the public / private mobile communication terminal, and the public / private mobile communication terminal A procedure for registering the individual telephone number (MIN) given from the network in the database as extension subscriber information is performed.

Next, for any wired telephone number, first identification information indicating whether the wired telephone number is a wired telephone number to which the terminal is connected or a wired telephone number to which the terminal is not connected, and the wired telephone number is A process of registering in a database the second identification information indicating whether or not to use the simultaneous call receiving service and the wired telephone number of the public / private mobile communication terminal called by the simultaneous call receiving function. After the registration process, if an arbitrary wired telephone number is called, a wired terminal corresponding to the corresponding wired telephone number is called, and there is a public / private mobile communication terminal called simultaneously in conjunction with the wired telephone number. Call the corresponding public / private mobile communication terminal via the mobile communication network. It is possible to perform a procedure for charging for the use of the wired / wireless service for each extension subscriber. At the time of charging, an internal charging rate can be applied when using a private mobile communication network, and an external charging rate can be applied when using a public mobile communication network.

FIG. 3 is a system configuration diagram for explaining the concept of a wired / wireless telephone linked service system according to an embodiment of the wired / wireless linked device shown in FIG.

Referring to FIG. 3, the wired / wireless interlocking device (100) includes a wired switch (111), a mobile gateway (Mobile G / W) (112), and a pBSC (113).

The wired exchange (111) is a switching system for servicing a wired telephone network, and the mobile gateway (112) is a system for processing calls generated by wired / wireless subscribers. The pBSC (113) connects the mobile gateway (112) with the pBTS (210) and also connects to the BSC (40) of the public mobile communication network for general public mobile communication services.

In one embodiment, as an example in which the mobile gateway (112) is used as an exchange linked with the wired exchange (111), the public telephone network (PSTN) (10) is connected to the trunk line interface (Trunk) of the wired exchange (111). NO. 7 Link via signaling.

In the wired switchboard (111), an extension subscriber card (SLC) interface is connected to a mobile line interface (Trunk) of the mobile gateway (112) via an E1 signaling. Here, E1 is a European standard for a 2.048 Mbps digital line with 32 time slots. As another example, T1 is a European standard for 24 channels of 1.544 Mbps digital lines, and T3 (DS3) is a digital signal level 3 operating at 44.736 Mbps.

That is, when allocating a wired telephone number to an arbitrary subscriber for a wired telephone service, the wired switchboard (111) calls the SLC interface to which the wired telephone number is allocated to the wired telephone terminal (250) of the subscriber. Instead of directly connecting via a line, the SLC interface is once connected to the central office interface of the mobile gateway (112) and sent to the mobile gateway (112).

The mobile gateway (112) allocates the line of the subscriber of the wired telephone service extension of the wired switchboard (111) received through the central office line interface to its own SLC interface, and connects to the corresponding wired telephone terminal (250) via the telephone line. Connect.

Thus, the wired telephone terminal (250) is connected to the SLC interface of the wired exchange (111) via the SLC interface of the mobile gateway (112) and the central office interface. Therefore, when hooking off the receiver for a telephone call, the wired telephone terminal (250) hears a dial tone provided by the wired telephone exchange (111).

In addition, the wired switchboard (111) can provide a wired telephone service to its own extension subscriber, thereby assigning a wired telephone number to each subscriber within a range that the SLC interface can accept. The wired switchboard (111) may include a database including a wired telephone number assigned to an extension subscriber or the like. This database is embodied in memory.

Here, the wired telephone number is composed of a generally used wired telephone number having a wired telephone terminal (250) connected to its end, and a virtual wired telephone number to which only the telephone number is assigned without connecting the wired telephone terminal (250). It is possible.

However, on the side of the wired exchange (111), the general wired telephone number and the virtual wired telephone number are not separately distinguished. This is because the wired exchange (111) assigns the telephone number for any extension subscriber to the SLC interface and terminates its role by sending it to the central line interface of the mobile gateway (112) via the SLC interface. Connecting or not connecting the wired telephone terminal (250) to the end of the given telephone number is a matter related to the mobile gateway (112), and the wired exchange (111) simply uses the same information as the extension subscriber information. Just manage it.

On the other hand, the mobile gateway 112 is connected to the pBSC 113 via the E1 signaling, and performs a function of linking the wired telephone service of the wired exchange 111 and the mobile communication service of the pBSC 113.

That is, the line allocated by the mobile gateway 112 in connection with the pBSC 113 via the E1 signaling is related to the wireless terminal.

The mobile gateway (112) has a database (112b) for the wired telephone numbers assigned from the wired exchange (111). This database (112b) can be embodied in the memory (112a). That is, as shown in FIG. 4, the database stores information indicating whether or not each telephone number is a virtual telephone number and information indicating whether or not the telephone number is registered in the multiple incoming call service.

For example, if the field indicating whether or not a virtual phone can be used is set to 0, it is a wired phone number to which a wired terminal is connected, and if it is set to 1, this phone number is a virtual phone number of a wireless terminal. Represents

On the other hand, if it is set to 0 in the field indicating whether multiple incoming calls can be made, it indicates that the service is limited to the existing service for calling the wired telephone terminal corresponding to the corresponding wired telephone number. For example, it indicates that the service is registered as a service capable of performing multiple incoming calls.

Accordingly, when an arbitrary wired telephone number registered with the multiple incoming call service is called, the mobile gateway (112) transmits specific information on the virtual wired telephone number corresponding to the wireless terminal called simultaneously with the wired telephone number. If necessary, it requests the information from pBSC (113).

When the information on the virtual telephone number of the wireless terminal connected to the corresponding wired telephone number is received from the pBSC (113), the corresponding virtual telephone number is searched for in its own database, and the wireless terminal corresponding to the virtual telephone number is identified by the pBSC (113). And pBST (210).

On the other hand, when the mobile gateway (112) receives a calling service request from an arbitrary wireless terminal from the pBSC (113), the mobile gateway (112) transmits the calling number and the caller ID of the wireless terminal received from the corresponding wireless terminal to the wired exchange (111). I do.

At this time, the caller ID of the wireless terminal transmitted to the wired exchange (111) is the virtual wired telephone number (for example, 02-CCC-DDDD) assigned to the wireless terminal. As a result, the wired exchange (111) sends the caller ID and calls the subscriber of the calling number.

At this time, the subscriber of the calling number can be an internal subscriber of the wired exchange (111) or an external subscriber who can call via the PSTN (10).

The pBSC (113) performs a function corresponding to the BSC in the public mobile communication system, that is, a radio link control, a handoff function, and the like.

The pBSC (56) controls the pBTS (210) to support a public mobile network and a private mobile communication network service, and analyzes call processing and other supplementary services of a subscriber and a mobile gateway (112). Handles various interfaces for interlocking.

For this reason, when a private mobile communication service is to be provided, a subscriber of a wireless terminal adds predetermined identification information to a calling telephone number for service discrimination.

Therefore, the pBSC (113) uses this identification information to distinguish whether the outgoing call is a call requesting a public mobile communication service or otherwise a call requesting a private mobile communication service. To

That is, it is determined whether the call from the wireless terminal transmitted from the pBTS (210) is a call for requesting a public mobile communication service or otherwise a call for requesting a private mobile communication service. If the call is a public mobile communication service call, the call is clearly bypassed to the BSC (40) of the public mobile communication network. If the call is a private mobile communication service call, the mobile communication service is provided so that the private mobile communication service is provided. The information is transmitted to the gateway (112).

As an example, if the user inputs a telephone number "# 212" through the wireless terminal, the pBSC (113) includes the identification number "#" that desires to use the private mobile communication service. It determines that it is desired to use the mobile communication service, and transmits a call request signal including the telephone number "212" to the mobile gateway (112) so that it can communicate with the extension subscriber with the extension number "212". I do.

Also, if the user inputs the telephone number "# 02-212-8866", the pBSC (113) contains the identification character "#" that desires to use the private mobile communication service. It determines that the user wants to use the service, and transmits a call request signal including the telephone number “02-212-8866” to the mobile gateway (112), and transmits the signal via the public telephone network through the wired exchange (111). A call can be made with a public telephone network subscriber having a telephone number "02-212-8866".

Also, if the user inputs the telephone number "# 016-212-8866", the pBSC (113) includes the identification character "#" for using the private mobile communication service. It is determined that the user wants to use the service, and a call request signal including the telephone number "016-212-8866" is transmitted to the mobile gateway (112), and the call is transmitted via the public telephone network via the wired exchange (111). A call can be made with a public mobile communication service subscriber of "016-212-8866" via a public mobile communication network.

Further, as shown in FIG. 5, the pBSC (113) includes a MIN number (for example, 016-AAA-BBBB) assigned to an arbitrary wireless terminal in a public mobile communication network and a virtual wired telephone assigned to the wireless terminal. A database (113b) for the numbers (for example, 02-CCC-DDDD) is provided.

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

For example, if the field indicating the existence of the virtual wired number is set to 0, there is no virtual wired number, and if it is set to 1, it means that there is a virtual wired telephone number corresponding to the MIN number. And the corresponding virtual wired telephone number is stored.

Therefore, when the virtual wired telephone number is called by the mobile gateway 112, the corresponding wireless terminal can be called.

On the other hand, when an arbitrary wireless terminal requests a calling service through the pBTS 210, it can be roughly classified into two cases.

First, there is a case where a call is requested using a private mobile communication service. In such a case, by sending the MIN number assigned to the public mobile communication network to the caller ID transmitted from the pBTS (210), the caller ID is changed to the virtual wired telephone number with reference to the database shown in FIG. And send it via the mobile gateway (112) and the wired exchange (111).

On the other hand, when the private mobile communication service is not used, the MIN number assigned to the public mobile communication network is transmitted to the caller ID transmitted from the pBTS (210), so that the public mobile communication is performed without changing the caller ID. The information is transmitted to the BSC (40) of the communication network.

Further, the pBSC (113) manages a database (113c) for the multiple incoming call service in the memory (113a). That is, when a wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming calls are set in a wired telephone terminal provided in a house and a corresponding wired telephone number are called, a virtual wired terminal assigned to a wireless terminal called simultaneously. It manages a database (113c) for telephone numbers.

Thereby, when inquiring about the virtual telephone number which is multiplexed with respect to the wired telephone number (for example, 02-XXX-YYYY) in which the multiple incoming call is set in the mobile gateway (112), the corresponding wired telephone number is searched in the database (113c). A number (e.g., 02-XXX-YYYY) can be retrieved, and a virtual telephone number (02-CCC-DDDD) linked to the wired telephone number can be retrieved and responded to the mobile gateway (112).

That is, databases (112b, 113c) are constructed in each of the mobile gateway (112) and the pBSC (113) for the multiple incoming call service. The database (112b) constructed in the mobile gateway (112) stores information on whether or not an arbitrary wired telephone number has been multiplexed and information on a virtual wired telephone number assigned to each wireless terminal. .

On the other hand, the database (113c) constructed in the pBSC (113) includes information on an arbitrary wired telephone number for which multiple incoming calls are set, and a virtual wired telephone number of a wireless terminal called by the multiple incoming calls to the wired telephone number. Has been saved. The database 113b and the database 113c may be implemented as one database.

In the wired / wireless interlocking device (100) configured as described above, not only a wired telephone service for a wired telephone terminal but also an incoming call to a designated wireless terminal is possible when calling a virtual wired telephone. In addition, when calling a wired telephone, a wired / wireless simultaneous call can be made at the mobile gateway (112) to receive a call at a desired terminal.

When there is a call from the PSTN (10) to the virtual wired telephone, the wired exchange (111) calls the mobile gateway (112). The mobile gateway (112) calls a wireless terminal in the mobile zone (200) via the pBSC (113) and the pBTS (210) according to the virtual wired telephone number.

When an incoming call response is received from the wireless terminal, the call is connected. If no incoming call response is received, the service is terminated according to the wired telephone service procedure.

FIG. 6 shows a procedure for calling a corresponding wire phone or wireless terminal when calling a wire phone in the wired / wireless phone link system shown in FIG.

An incoming call procedure will be described with reference to incoming routes (P1, P2) shown in FIG.

When an arbitrary subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the wired exchange (111) is called for the corresponding wired telephone number via the PSTN (10) (S1). Then, it is determined whether or not the called telephone number is a wired subscriber number (S2). If the result is a wired subscriber number, it is transmitted to the mobile gateway (112) via the wired subscriber line (S3). On the other hand, if it is not a wired subscriber number, a virtual subscriber line 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 exchange (111). First, the mobile gateway (112) determines whether or not the corresponding telephone number is a multiple incoming call number based on its own database (112b) shown in FIG. 4 (S5). If the result of the determination is that it is not a multiple incoming number, the call is distributed to the wired subscribers (S6). Then, the wired terminal (250) responds (S7).

On the other hand, as a result of judging whether or not the number is a multiple incoming number, if the number is a multiple incoming number, the call is first distributed to the wired subscribers (S8) (P1). Further, it requests the pBSC (113) for the virtual wired telephone number designated as the corresponding wired number (S9). Requesting a virtual wired telephone number from the pBSC (113) by the mobile gateway (112) means that multiple incoming calls are set for any wired terminal in the database (112b) of the mobile gateway (112). This is because only information that informs the user is stored.

On the other hand, since the pBSC (113) stores the direct information for the corresponding wireless terminal for which the multiplex reception is set for the wire number, the multiplex reception from the mobile gateway (112) to the pBSC (113). Requesting a virtual wired telephone number corresponding to the wireless terminal to be used.

Accordingly, the pBSC (113) searches its own database (113c) for a virtual wired telephone number for the corresponding wired telephone number, and provides the virtual wired telephone number to the mobile gateway (112). The mobile gateway (112) distributes the call to the corresponding wireless terminal (220) via the pBSC (113) and the pBTS (210) (S10) (P2). Then, one of the wired terminal (250) and the wireless terminal (220) responds (S11). Also, when the wired terminal does not respond, the wireless terminal can receive the incoming call service anywhere in the mobile zone (200).

On the other hand, when it is determined whether or not it is a wired subscriber number (S2), if the determination result is that the mobile subscriber (112) is not a wired subscriber number, the mobile gateway (112) determines whether the virtual subscriber assigned to the wireless terminal (220) is The line is selected and transmitted to the mobile gateway (112), and the call is distributed to the corresponding wireless terminal via the pBSC (113) and the pBTS (210) (S12). Thereby, the corresponding wireless terminal (220) responds (S13).

7 shows a procedure in which a wireless terminal subscriber makes a call to an external subscriber, FIG. 8 shows a procedure in which the wireless terminal subscriber makes a call to an internal subscriber, and FIG. Or to an internal subscriber.

The incoming call procedure of FIG. 9 will be described with reference to the incoming call path (P3) of FIG. 7 and the incoming call path (P4) of FIG.

The wireless terminal (220) (for example, 016-AAA-BBBB) calls the other party's number (for example, 031-ZZZ-ZZZZZ or 02-XXX-XXXX) (S21). The call generated by the wireless terminal (220) is transmitted to the mobile gateway (112) via the pBTS (210) and the pBSC (113) (S22).

At this time, the pBSC (112) changes the caller ID (Caller ID) (016-AAA-BBBB) assigned to the wireless terminal to the virtual wired number assigned to the wireless terminal (for example, 02-CCC-DDDD). (S23). At this time, the change of the caller ID refers to the database (113b) shown in FIG.

The mobile gateway (112) determines whether or not the calling number sent from the wireless terminal is an external calling number (S24). If it is an external calling number, only the call is stored in the message and transmitted to the wired exchange (111). The wired exchange (111) calls the external subscriber of the corresponding telephone number via the PSTN (10) (P3) (S26).

On the other hand, when the mobile gateway 112 determines whether or not the number is an external calling number (S24), if the result of the determination is that the number is not an external calling number, the internal subscribers (220, 240, 260) in the mobile zone 200 Is called (P4) (S27).

At this time, the billing process can be billed via a billing device (not shown) connected to the wired exchange (111). At this time, the call between the internal subscribers made by the wired / wireless interlocking device (100) in the mobile zone (200) can be operated free of charge without additional charge. In such a case, the subscriber can make a call between the internal subscribers and the like without additional billing.

FIGS. 10 and 11 show a procedure in which an incoming call is re-routed when the mobile zone is absent.

The rerouting procedure of FIG. 11 will be described with reference to the incoming routes (P5, P6, P7A) of FIG.

When an external subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the wired exchange (111) is called for the corresponding wired telephone number via the PSTN (10), and It is determined whether or not the called telephone number is a wired subscriber number (S31). If the result is a wired subscriber number, it is transmitted to the mobile gateway (112) via the wired subscriber line (S32). On the other hand, if it is not a wired subscriber number, the virtual subscriber line 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 exchange (111). At this time, the mobile gateway (112) has a database as shown in FIG. The mobile gateway (112) determines whether or not the corresponding telephone number is a multiple incoming number in the database (112b) (S34). If the result of the determination is that it is not a multiple incoming number, it means that only the wired telephone terminal is to be called, so the call is distributed to wired subscribers (S35). On the other hand, if the result of the determination is that the number is a multiple incoming number, the call is first distributed to wired subscribers (S36). Next, the mobile gateway (112) requests the virtual number from the pBSC (113), and the virtual number corresponding to the corresponding wired telephone number is provided from the pBSC (113), and the virtual number is provided via the pBSC (113) and the pBTS (210). The call is distributed to the wireless terminal (220) (S37). On the other hand, when the mobile gateway (112) receives the wired telephone number via the virtual subscriber line allocated to the wireless terminal, the mobile gateway (112) receives the corresponding wireless terminal (220) via the pBSC (113) and the pBTS (210). ).

Next, if at least one of the wired terminal (250) and the wireless terminal (220) responds in the mobile zone (200), call processing is performed accordingly, and if not, the mobile terminal joins the mobile zone (200). It is determined whether the person is absent (S38). When it is determined that there is no response from the wired terminal (250) or the wireless terminal (220) in the mobile zone (200) and the mobile zone (200) is absent, the mobile gateway (112) communicates with the wired exchange (111). , A PSTN (10) and a CDMA network (20) to call a wireless terminal (50a) in the public mobile communication network via a BTS (50) in the public mobile communication network (S39). On the other hand, if the subscriber is in the mobile zone (200), but there is no response, the subscriber is unable to receive a call. (S40).

<Second embodiment>

FIG. 12 is a system configuration diagram for explaining the concept of a wired / wireless telephone linked service system according to another embodiment of the wired / wireless linked apparatus shown in FIG.

Referring to FIG. 12, the wired / wireless interlocking device (100) includes a wired switch (121), a mobile gateway (Mobile G / W) (122), and a pBSC (123).

The description of the mobile zone (200) including the pBTS (210) in the drawing is the same as the description of FIG.

In the embodiment, as an example in which the mobile gateway (122) is used as a tandem exchange, the public telephone network (PSTN) (10) sets the central office (Trunk) of the mobile gateway (122) to NO. 7 Link via signaling.

The wired exchange (121) sets the central office interface (Trunk) of the mobile gateway (122) to NO. 7 are connected to each other via a signal ring to provide a wired telephone service to subscribers and the like outside the mobile zone (200).

The wired exchange (121) is a system for providing a wired telephone network to subscribers outside the mobile zone (200), and the mobile gateway (122) is a call generated by wired / wireless subscribers in the mobile zone (200). Is a system for processing.

That is, the mobile gateway (122) performs call processing for the wired telephone network service and the mobile communication service to the wired / wireless subscribers (220-270) in the mobile zone (200). This is a system for providing a wired telephone service to wired subscribers (not shown) outside the zone (200).

For example, when a telephone office is set up for a large apartment complex, a pBTS (210) is provided, and a pBTS (210) is provided in an apartment complex located in a mobile zone (200) that can provide mobile communication services. Since there are no resident wired / wireless subscribers and no pBTS (210) installed, mobile communication services cannot be provided, and the mobile phone is located outside the mobile zone (200) that can only provide general wired telephone services. There may be wired telephone service subscribers residing in apartment complexes.

In the case of a large-scale apartment complex as described above, the number of subscribers is large, so that one mobile gateway (122) can be used for subscribers within the mobile zone (200) and subscribers outside the mobile zone (200). In some cases, it is not possible to provide a wired telephone service to the exchange because of the capacity of the exchange.

Therefore, in the case of a wired / wireless telephone subscriber in the mobile zone (200), the corresponding communication service is provided by the mobile gateway (122), and a separate wired switch ( 121) to provide the corresponding communication service.

Accordingly, when there is a call to an arbitrary wired telephone number via the PSTN (10), the mobile gateway (122) determines whether or not the telephone number is an incoming call to its own extension subscriber, and determines the result. If the call is not an extension call, for example, if it is a subscriber telephone number outside the mobile zone (200), the call is transmitted to the wired exchange (121) by a tandem call, and the corresponding service is provided by the wired exchange (121). To do.

The pBSC (123) connects the mobile gateway (122) and the pBTS (210), and also connects to the BSC (40) of the public mobile communication network for general public mobile communication services.

That is, when the mobile gateway 122 assigns a wired telephone number to an arbitrary subscriber for wired telephone service, the mobile gateway 122 transmits an SLC interface to which the wired telephone number is assigned to the subscriber's wired telephone terminal 250. Connect directly via Therefore, when hooking off the handset for a call, the wired telephone terminal (250) hears the dial tone provided by the mobile gateway (122).

Also, the mobile gateway (122) can provide a wired telephone service to its own extension subscriber, thereby assigning a wired telephone number to each subscriber within a range that the SLC interface can accept.

Here, the wired telephone number is a generally used wired telephone number with a wired telephone terminal (250) connected to its end, and a virtual wired telephone number to which only the telephone number is assigned without connecting the wired telephone terminal (250). Is possible.

On the other hand, the mobile gateway 122 is connected to the pBSC 123 via the E1 signaling, and performs a function of linking the mobile communication service of the pBSC 123.

To this end, the mobile gateway (122) has a database (122b) for wired telephone numbers in the memory (122a). That is, as shown in FIG. 4, the database (112b) stores information indicating whether or not each telephone number is a virtual telephone number and information indicating whether or not the telephone number is registered in the multiple incoming call service.

For example, if the field indicating virtual telephone availability is set to 0, it is a wired telephone number to which a wired terminal is connected, and if it is set to 1, this telephone number is a virtual telephone number of a wireless terminal. Represents

On the other hand, if it is set to 0 in the field indicating whether or not multiple incoming calls are possible, it indicates that the service is limited to the existing service that calls the wired telephone terminal corresponding to the corresponding wired telephone number. For example, it indicates that the service is registered as a service capable of performing multiple incoming calls.

Accordingly, when an arbitrary wired telephone number registered with the multiple incoming call service is called, the mobile gateway (122) transmits specific information on the virtual wired telephone number corresponding to the wireless terminal called at the same time as the wired telephone number. If necessary, it requests the information from pBSC (123).

When the information about the virtual telephone number of the wireless terminal connected to the corresponding wired telephone number is received from the pBSC (123), the corresponding virtual telephone number is called to the pBSC (123), and the pBSC (123) stores the virtual telephone number in the database (123b). A wireless terminal telephone number corresponding to the number is searched, and the corresponding wireless terminal is called via pBST (210).

On the other hand, when the mobile gateway (122) receives a calling service request from an arbitrary wireless terminal from the pBSC (123), the mobile gateway (122) sends the calling number and the caller ID of the wireless terminal received from the corresponding wireless terminal, and the subscriber of the corresponding calling number. Call.

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

In this case, the calling subscriber may be an internal subscriber of the mobile gateway (122) or may be an external subscriber who can call via the PSTN (10).

The pBSC (123) performs a function corresponding to the BSC in the public mobile communication system, that is, a radio link control, a handoff function, and the like.

The pBSC (123) controls the pBTS (210) to support a public mobile network and a private mobile communication network service, and analyzes a subscriber's call and other supplementary services and a mobile gateway (122). Process various interfaces for interlocking with.

For this reason, when a private mobile communication service is to be provided, a subscriber of a wireless terminal adds predetermined identification information to a calling telephone number for service discrimination.

Therefore, the pBSC (123) uses this identification information to distinguish whether the outgoing call is a call requesting a public mobile communication service or otherwise a call requesting a private mobile communication service.

That is, it is determined whether the call from the wireless terminal transmitted from the pBTS (210) is a call for requesting a public mobile communication service or a call for requesting a private mobile communication service otherwise. If the call is a public mobile communication service call, the call is clearly bypassed to the BSC (40) of the public mobile communication network. If the call is a private mobile communication service call, the private mobile communication service is provided. It communicates to the mobile gateway (122).

As an example, if the user inputs a telephone number "# 212" through the wireless terminal, the pBSC (123) includes the identification number "#" that desires to use the private mobile communication service. It determines that it is desired to use the mobile communication service, and transmits a call request signal including the telephone number "212" to the mobile gateway (122) so that it can communicate with the extension subscriber with the extension number "212". I do.

Also, if the user inputs the telephone number "# 02-212-8866", the pBSC (123) includes the identification character "#" that desires to use the private mobile communication service. It determines that the user desires to use the service, and transmits a call request signal including the telephone number "02-212-8866" to the mobile gateway (122), and transmits the telephone number "02-212-" via the PSTN (10). It is possible to communicate with an 8866 ″ public telephone network subscriber.

Also, if the user inputs the telephone number "# 016-212-8866", the pBSC (123) contains the identification character "#" that desires to use the private mobile communication service. It is determined that the user wants to use the service, and a call request signal including the telephone number "016-212-8866" is transmitted to the mobile gateway (122), and "016-212-8866" is transmitted via the PSTN (10). To enable calls with public mobile communication service subscribers. Other than the "#", other identifiers can be used.

Further, as shown in FIG. 5, the pBSC (123) includes a MIN number (for example, 016-AAA-BBBB) assigned to an arbitrary wireless terminal in a public mobile communication network and a virtual wired telephone assigned to the wireless terminal. A database (123c) for the numbers (for example, 02-CCC-DDDD) is provided.

That is, the database (123c) stores information indicating whether a virtual wired number exists for each MIN number of an arbitrary wireless terminal and, if there is a corresponding virtual wired number, the wired number information.

For example, if the field indicating the existence of the virtual wired number is set to 0, there is no virtual wired number, and if it is set to 1, it means that there is a virtual wired telephone number corresponding to the MIN number. And the corresponding virtual wired telephone number is stored.

Therefore, when the virtual wired telephone number is called by the mobile gateway 122, the corresponding wireless terminal can be called.

On the other hand, when an arbitrary wireless terminal requests a calling service through the pBTS 210, it can be roughly classified into two cases.

First, there is a case where a call is requested using a private mobile communication service. In such a case, when the MIN number assigned to the public mobile communication network is sent to the caller ID transmitted from the pBTS (210), the caller ID is virtually referenced with reference to the database (123c) shown in FIG. It is converted to a wired telephone number and sent to the mobile gateway (122).

On the other hand, when the private mobile communication service is not used, the MIN number assigned to the public mobile communication network is transmitted to the caller ID transmitted from the pBTS (210), so that the public mobile communication is performed without changing the caller ID. The information is transmitted to the BSC (40) of the communication network.

Further, the pBSC (123) manages a database (123c) for the multiple incoming call service. That is, among the wired telephone terminals provided in the house, the wired telephone number (for example, 02-XXX-YYYY) for which the multiple incoming call is set and the wireless terminal that is simultaneously called when the corresponding wired telephone number is called. It manages a database (123c) for virtual wired telephone numbers.

Thereby, when inquiring the multiplexed virtual wired telephone number with respect to the wired telephone number (for example, 02-XXX-YYYY) for which the multiple incoming call is set by the mobile gateway (122), the corresponding wired telephone number is checked in the database (123c). A number (e.g., 02-XXX-YYYY) can be retrieved to find a virtual telephone number (02-CCC-DDDD) linked to the wired telephone number and respond to the mobile gateway (122).

That is, a database is constructed in each of the mobile gateway (122) and the pBSC (123) for the multiple incoming call service. In the database (122b) constructed in the mobile gateway (122), information as to whether or not an arbitrary wired telephone number has been received multiple times and information on a virtual wired telephone number assigned to each wireless terminal are stored. .

On the other hand, the database (123c) constructed in the pBSC (123) contains information on an arbitrary wired telephone number for which multiple incoming calls are set, and a virtual wired telephone number of a wireless terminal called by the multiple incoming call to the wired telephone number. Has been saved.

In the wired / wireless interlocking device (100) configured as described above, not only a wired telephone service for a wired telephone terminal but also an incoming call to a designated wireless terminal is possible when calling a virtual wired telephone. In addition, when calling a wired telephone, the mobile gateway (122) can simultaneously make a wired / wireless call and receive a call to a desired terminal.

When there is a call from the PSTN (10) to the virtual wired telephone, the mobile gateway (122) establishes a wireless connection in the mobile zone (200) via the pBSC (123) and the pBTS (210) corresponding to the virtual wired telephone number. Call the terminal.

When an incoming call response is received from the wireless terminal, the call is connected. If no incoming call response is received, the service is terminated according to the wired telephone service procedure.

FIG. 13 and FIG. 14 show a procedure in which a wired telephone and a wireless terminal are simultaneously called when a wired telephone is called.

The incoming call procedure will be described with reference to the incoming call paths (P7, P8) shown in FIG. 13 and the flowchart shown in FIG.

When an arbitrary subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the mobile gateway (122) is called for the corresponding wired telephone number via the PSTN (10) and the called. It is determined whether the received telephone number is an incoming call to an extension subscriber to the mobile gateway (122) (S101). If it is determined that the call is not an extension call, the call is transmitted to the wired exchange (121) by a tandem call (S102). On the other hand, if the call is an extension call, the mobile gateway (122) analyzes the telephone number transmitted from the PSTN (10). At this time, the mobile gateway (122) can know whether the corresponding telephone number is a wired telephone number and whether it is a multiple incoming number through the database shown in FIG.

First, it is determined whether it is a wired subscriber telephone number (S103). If it is not a wired subscriber number, it is a wireless subscriber number, so the virtual wired telephone number is called to pBSC (123). The pBSC (123) searches for the telephone number of the wireless terminal corresponding to the virtual wired telephone number and distributes the call to the wireless terminal (220) via the pBTS (210) (S104). Then, the corresponding wireless terminal (220) responds (S105).

On the other hand, if the result of the determination is that it is a wired subscriber number, it is determined whether it is a telephone number for which wired / wireless multiplex incoming is set (S106). As a result of judging whether it is a multiple incoming number or not, if it is not a multiple incoming number, the call is distributed to wired subscribers (S111). Thereby, the wired terminal (250) responds (S112). However, if it is a multiple incoming number, the call is first distributed to wired subscribers (S106). Then, the virtual telephone number of the wireless terminal connected to the corresponding telephone number is requested to the pBSC (123), and when the virtual telephone number is provided from the pBSC (123), the virtual telephone number is called to the pBSC (123). The pBSC (123) searches for the telephone number of the wireless terminal corresponding to the virtual telephone number and distributes the call to the wireless terminal (220) via the pBTS (210) (S109). Then, one of the wired terminal (250) and the wireless terminal (220) responds (S111).

FIG. 15 shows a procedure in which a wireless terminal subscriber makes a call to an external subscriber, FIG. 16 shows a procedure in which a wireless terminal subscriber makes a call to an internal subscriber, and FIG. Or a flow chart for sending to an internal subscriber.

The incoming call procedure of FIG. 17 will be described with reference to the incoming call path (P9) of FIG. 15 and the incoming call path (P10) of FIG.

The wireless terminal (220) (for example, 016-AAA-BBBB) calls the other party's number (for example, 031-ZZZ-ZZZZZ or 02-XXX-XXXX) (S121). The call generated by the wireless terminal (220) is transmitted to the mobile gateway (122) via the pBTS (210) and the pBSC (123) (S22).

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

The mobile gateway (122) determines whether the calling number sent from the wireless terminal is an external calling number (S124). If the result of the determination is that the number is an external calling number, the external subscriber of the telephone number is called via the PSTN (10) (P9) (S125).

On the other hand, when the mobile gateway (112) determines whether or not the call is an outside call number (S124), if the judgment result is that the call is not an outside call number, the internal subscribers (220, 240, 260) in the mobile zone (200) Is called (P10) (S126).

At this time, the billing process can be billed via billing equipment (not shown) connected to the tandem mobile gateway (122).

At this time, the call between the internal subscribers made by the wired / wireless interlocking device (100) in the mobile zone (200) can be operated free of charge without additional charge. In such a case, the subscriber can make a call between the internal subscribers and the like without additional billing.

FIGS. 18 and 19 show a procedure in which an incoming call is re-routed when the mobile zone is absent.

The rerouting procedure in FIG. 19 will be described with reference to the incoming routes (P11, P12, P13) in FIG.

When an arbitrary subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the mobile gateway (121) is called for the corresponding wired telephone number via the PSTN (10) and is called. It is determined whether or not the received telephone number is an incoming call to an extension subscriber to the mobile gateway (121) (S131). If the result of the determination is that the call is not an extension call, the call is transmitted to the wired exchange by a tandem call (S132).

On the other hand, if the call is an extension call, the mobile gateway (122) analyzes the telephone number transmitted from the PSTN (10). At this time, the mobile gateway (122) can know whether or not the corresponding telephone number is a wired telephone number and whether or not the corresponding telephone number is a multiple incoming call number through its own database.

First, it is determined whether it is a wired subscriber telephone number (S133). If the result of the determination is that it is a wired subscriber number, it is determined whether the telephone number is a telephone number for which wired / wireless multiplex incoming is set (S134). If the result of the determination is that it is not a multiple incoming call number, the system waits until the corresponding wired terminal answers with the call distributed only to the wired subscriber (S135). On the other hand, if the result of the determination is that the number is a multiple incoming number, the call is first distributed to wired subscribers (S136). Further, the virtual number is requested to the pBSC (123), and the virtual number is provided from the pBSC (123), and the call is distributed to the corresponding wireless terminal (220) via the pBSC (123) and the pBTS (210) (S137). ). On the other hand, when the mobile gateway (121) receives the wired telephone number via the virtual subscriber line allocated to the wireless terminal, the mobile gateway (121) receives the corresponding wireless terminal (220) via the pBSC (123) and the pBTS (210). ).

Next, if at least one of the wired terminal (250) and the wireless terminal (220) answers in the mobile zone (200), call processing is performed accordingly, and if not, the mobile zone (200) switches to the mobile zone (200). It is determined whether the subscriber is absent (S138). When it is determined that there is no response from the wired terminal (250) or the wireless terminal (220) in the mobile zone (200), it is determined that the mobile zone (200) is absent in the mobile gateway (112). A wireless terminal (50a) in the public mobile communication network is called via the BTS (50) in the public mobile communication network via (20) (S139). If you are in the mobile zone (200) but there is no response, a voice guidance message such as "The subscriber is unable to receive a call, please call next" Can be transmitted (S140).

<Third embodiment>

FIG. 20 is a system configuration diagram for explaining the concept of a wired / wireless telephone linked service system according to another embodiment of the wired / wireless linked apparatus shown in FIG.

Referring to FIG. 20, the wired / wireless interlocking device (100) includes a collective exchange (131) that performs a wired switching function and a mobile gateway (Mobile G / W) function, and a private base station controller (pBSC) (132). ).

The description of the mobile zone 200 including the pBTS 210 in the drawing is the same as the description of FIG.

The collective exchange (131) performs call processing for the wired telephone network service and the mobile communication service for the wired / wireless subscribers (220-270) in the mobile zone (200), and also performs wired subscription outside the mobile zone (200). This is a system for providing a wired telephone service to a person (not shown).

For example, when installed in a small apartment complex, a pBTS (210) is provided and lives in a paulownia located in a mobile zone (200) where a wireless service can be provided by the pBTS (210). A wired / wireless telephone link service is provided to wired / wireless subscribers and the like, and a wired telephone service resident in a paulownia located outside the mobile zone (200) where mobile communication services cannot be provided by the pBTS (210). It also provides general wired telephone services to persons and the like.

The pBSC (132) connects the collective exchange (131) to the pBTS (210), and also connects to the BSC (40) of the public mobile communication network for general public mobile communication services.

In the embodiment, as an example in which the functions of the mobile gateway and the wired exchange are implemented in one collective exchange (131), the public switched telephone network (PSTN) (10) is connected to the central office (Trunk) of the collective exchange (131). NO. 7 Link via signaling.

In the wired switchboard (111), an extension subscriber card (SLC) interface is connected to each of the wired telephone terminals (023, 250, 27) via a telephone line.

That is, when allocating a wired telephone number to an arbitrary subscriber for wired telephone service, the collective exchange (131) calls the SLC interface to which the wired telephone number is allocated to the subscriber's wired telephone terminal (250). Connect directly via wire. Therefore, when the wire telephone terminal (250) hooks off the handset for a call, it hears the dial tone provided by the collective exchange (131).

In addition, the collective exchange (131) can provide a wired telephone service to its own extension subscriber, thereby assigning a wired telephone number to each subscriber within a range that the SLC interface can accept.

Here, the wired telephone number is composed of a generally used wired telephone number having a wired telephone terminal (250) connected to its end, and a virtual wired telephone number to which only the telephone number is assigned without connecting the wired telephone terminal (250). It is possible.

On the other hand, the collective exchange (131) is connected to the pBSC (132) via the E1 signaling and performs a function of interlocking the mobile communication service of the pBSC (132).

For this purpose, the collective exchange (131) has a database (131b) for wired telephone numbers in the memory (131a). That is, as shown in FIG. 4, the database (131b) stores information indicating whether or not each telephone number is a virtual telephone number and information indicating whether or not the telephone number is registered in the multiple incoming call service. .

For example, if the field indicating virtual telephone availability is set to 0, it is a wired telephone number to which a wired terminal is connected, and if it is set to 1, this telephone number is a virtual telephone number of a wireless terminal. Represents

On the other hand, if it is set to 0 in the field indicating whether multiple incoming calls are possible, it indicates that the service is limited to the existing service for calling the wired telephone terminal corresponding to the corresponding wired telephone number, and if it is set to 1, Indicates that the service is registered as a service capable of performing multiple incoming calls.

Accordingly, when an arbitrary wired telephone number in which the multiple incoming call service is registered is called, the collective exchange (131) transmits specific information on the virtual wired telephone number corresponding to the wireless terminal called simultaneously with the wired telephone number. If necessary, it requests the information from pBSC (132).

When the virtual telephone number of the wireless terminal connected to the corresponding wired telephone number is received from the pBSC (132), the virtual telephone number is called to the pBSC (132). The pBSC (132) searches the database for the wireless terminal telephone number corresponding to the virtual telephone number, and calls the corresponding wireless terminal via the pBST (210).

On the other hand, when receiving a calling service request from an arbitrary wireless terminal via the pBSC (132), the collective exchange (131) sends the calling number and the caller ID of the wireless terminal received from the corresponding wireless terminal, and joins the calling number. Call the person.

At this time, the caller ID of the wireless terminal transmitted to the collective exchange (131) is the virtual wired telephone number (for example, 02-CCC-DDDD) assigned to the wireless terminal.

At this time, the calling subscriber may be an internal subscriber of the collective exchange (131) or may be an external subscriber who can call via the PSTN (10).

The pBSC (132) performs a function corresponding to the BSC in the public mobile communication system, that is, a radio link control, a handoff function, and the like.

The pBSC (132) controls the pBTS (210) to support the public mobile network and the private mobile communication network service, analyze the call processing of subscribers, and other supplementary services, and perform a collective exchange (131). Process various interfaces for interlocking with).

For this reason, when a private mobile communication service is to be provided, a subscriber of a wireless terminal adds predetermined identification information to a calling telephone number for service discrimination.

Therefore, the pBSC (113) uses this identification information to distinguish whether the outgoing call is a call requesting a public mobile communication service, or otherwise, a call requesting a private mobile communication service. .

That is, it is determined whether the call from the wireless terminal transmitted from the pBTS (210) is a call for requesting a mobile communication service for public use, or if not, a call for requesting a mobile communication service for private use. If the call is a public mobile communication service call, the call is clearly bypassed to the BSC (40) of the public mobile communication network. If the call is a private mobile communication service call, the private mobile communication service is provided. The information is transmitted to the collective exchange (131).

As an example, if the user inputs a telephone number "# 212" through the wireless terminal, the pBSC (132) includes the identification number "#" that desires to use the private mobile communication service. If it is determined that the mobile communication service is desired to be used, a call request signal including the telephone number "212" is transmitted to the collective exchange 131 so that a call can be made with the extension subscriber having the extension number "212". I do.

Also, if the user inputs the telephone number "# 02-212-8866", the pBSC (132) includes the identification character "#" that desires to use the private mobile communication service. It is determined that it is desired to use the service, and a call request signal including the telephone number "02-212-8866" is transmitted to the collective exchange (131), and the telephone number "02-212-" is transmitted via the PSTN (10). It is possible to communicate with an 8866 ″ public telephone network subscriber.

Also, if the user inputs the telephone number "# 016-212-8866", the pBSC (132) includes the identification character "#" for using the private mobile communication service. It is determined that it is desired to use the service, and a call request signal including the telephone number "016-212-8866" is transmitted to the collective exchange (131), and "016-212-8866" is transmitted via the PSTN (10). To enable calls with public mobile communication service subscribers.

Also, as shown in FIG. 5, the pBSC (132) includes a MIN number (for example, 016-AAA-BBBB) assigned to an arbitrary wireless terminal in a public mobile communication network and a virtual wired telephone assigned to the wireless terminal. A database (132b) for the numbers (for example, 02-CCC-DDDD) is provided.

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

For example, if the field indicating whether a virtual wired number exists or not is set to 0, there is no virtual wired number, and if it is set to 1, it means that there is a virtual wired telephone number corresponding to the MIN number. And the corresponding virtual wired telephone number is stored.

Therefore, even when a virtual wired telephone number is called by the collective exchange (131), the corresponding wireless terminal can be called.

On the other hand, when an arbitrary wireless terminal requests a calling service through the pBTS 210, it can be roughly classified into two cases.

First, there is a case where a call is requested using a private mobile communication service. In such a case, the MIN number assigned to the public mobile communication network is sent to the caller ID transmitted from the pBTS (210), thereby referring to the database shown in FIG. The data is converted and sent to the collective exchange (131).

On the other hand, when the private mobile communication service is not used, the MIN number assigned to the public mobile communication network is transmitted to the caller ID transmitted from the pBTS (210), so that the public mobile communication is performed without changing the caller ID. The information is transmitted to the BSC (40) of the communication network.

Further, the pBSC (132) manages a database (132c) for the multiple incoming call service in the memory (132a). That is, among the wired telephone terminals provided in the house, when a wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming calls are set and a corresponding wired telephone number are called, the virtual terminal assigned to the wireless terminal called simultaneously. It manages a database (132c) for wired telephone numbers.

Thereby, when inquiring about the multiplexed virtual wired telephone number with respect to the wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming call is set in the collective exchange (131), the corresponding wired telephone number (for example, , 02-XXX-YYYY) and a virtual telephone number (02-CCC-DDDD) linked to the wired telephone number, and can respond to the collective exchange (131).

That is, databases (131b, 132c) are constructed in each of the collective exchange (131) and the pBSC (132) for the multiple incoming call service. The database constructed in the collective exchange (131) stores information as to whether or not an arbitrary wired telephone number has been multiplexed and information on a virtual wired telephone number assigned to each wireless terminal.

On the other hand, a database constructed in the pBSC (132) stores information on an arbitrary wired telephone number for which multiple incoming calls are set and a virtual wired telephone number of a wireless terminal called by the multiple incoming call for the wired telephone number. I have.

In the wired / wireless interlocking device (100) configured as described above, not only a wired telephone service for a wired telephone terminal but also an incoming call to a designated wireless terminal is possible when calling a virtual wired telephone. Also, when calling a wired telephone, the collective exchange (131) can simultaneously make a wired / wireless call and receive a call to a desired terminal.

When there is a call from the PSTN (10) to the virtual wired telephone, the collective exchange (131) responds to the virtual wired telephone number by using the pBSC (132) and the pBTS (210) to communicate with the wireless in the mobile zone (200). Call the terminal.

When an incoming call response is received from the wireless terminal, the call is connected. If no incoming call response is received, the service is terminated according to the wired telephone service procedure.

FIG. 21 and FIG. 22 show a procedure in which a call is received by a wired telephone and a wireless terminal at the same time when a wired telephone is called.

The incoming call procedure will be described with reference to the incoming call path (P14, P15) shown in FIG.

When an arbitrary subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the collective exchange (131) calls the corresponding wired telephone number via the PSTN (10) and calls the telephone number. To analyze. At this time, the collective exchange (131) determines whether the telephone number is a wired subscriber number (S201). If it is not a wired subscriber number, it is a wireless terminal subscriber, so the call is distributed to the corresponding wireless terminal via the pBSC (132) and the pBTS (210) (S202). Thereby, the corresponding wireless terminal (220) responds (S203).

On the other hand, if it is a wired subscriber number and it is a wired subscriber number, it is determined whether or not the corresponding telephone number is a multiple incoming call number in its own database (131b) shown in FIG. S204). If the result of the determination is that the number is not a multiple called number, the call is distributed to the wired subscriber (S205), and the wired terminal responds (S206).

However, as a result of judging whether or not it is a multiple destination number, the collective exchange (131) first distributes the call to the wired subscriber if it is a multiple destination number (S207) (P14). Further, the virtual number is requested from the pBSC (132), the virtual number retrieved from the pBSC (132) is received, and the call is distributed to the corresponding wireless terminal (220) via the pBSC (132) and the pBTS (210). (S208) (P15). Then, one of the wired terminal (250) and the wireless terminal (220) responds (S209). When the wired terminal does not respond, the wireless terminal can receive the incoming call service anywhere in the mobile zone (200).

On the other hand, when it is determined whether it is a multiple incoming number (S202), if it is not a multiple incoming number, the call is distributed to the corresponding wireless terminal via the pBSC (132) and the pBTS (210) (S206). Thereby, the corresponding wireless terminal (220) responds (S207).

FIG. 23 shows a procedure in which a wireless terminal subscriber makes a call to an external subscriber, FIG. 24 shows a procedure in which a wireless terminal subscriber makes a call to an internal subscriber, and FIG. Or a flow chart for sending to an internal subscriber.

The incoming call procedure of FIG. 25 will be described with reference to the incoming call path (P16) of FIG. 23 and the incoming call path (P17) of FIG.

The wireless terminal (220) (for example, 016-AAA-BBBB) calls the other party's number (for example, 031-ZZZ-ZZZZZ or 02-XXX-XXXX) (S211). The call generated by the wireless terminal (220) is transmitted to the collective exchange (131) via the pBTS (210) and the pBSC (132) (S212).

At this time, the pBSC (132) changes the caller ID (Caller ID) (016-AAA-BBBB) assigned to the wireless terminal to a virtual wired number (for example, 02-CCC-DDDD) assigned to the wireless terminal ( S213). At this time, the change of the caller ID refers to the database (132b) shown in FIG.

The collective exchange (131) determines whether or not the calling number sent from the wireless terminal is an external calling number (S214). If it is an external calling number, the external subscriber of the corresponding telephone number is called via the PSTN (10) (P16) (S215).

On the other hand, when the collective exchange (131) determines whether or not it is an external calling number (S214), if the result of the determination is that it is not an external calling number, the internal subscribers (220, 240, 260) in the mobile zone (200) Is called (P17) (S216).

At this time, the charging process can be performed via charging equipment (not shown) connected to the collective exchange (131). At this time, the call between the internal subscribers made by the wired / wireless interlocking device (100) in the mobile zone (200) can be operated free of charge without additional charge. In such a case, the subscriber can make a call between the internal subscribers and the like without additional billing.

FIGS. 26 and 27 show a procedure in which an incoming call is re-routed when the mobile zone is absent.

The rerouting procedure in FIG. 27 will be described with reference to the incoming routes (P18, P19, P20) in FIG.

When an arbitrary subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the collective exchange (131) receives the corresponding wired telephone number via the PSTN (10) and is called. Analyze the phone number. At this time, the collective exchange (131) determines whether the telephone number is a wired subscriber number (S221). If it is determined that the telephone number is a wired subscriber number, the collective exchange (112) determines whether or not the corresponding telephone number is a multiple incoming number in its own database shown in FIG. 4 (S222). If the result of the determination is that it is not a multiple incoming number, the call is distributed to the wired subscribers (S223). However, if it is determined that the number is a multiple incoming number, the call is first distributed to the wired subscriber (P18) (S224). Next, the collective exchange (131) requests the virtual number from the pBSC (132), and the virtual number corresponding to the corresponding wired telephone number is provided from the pBSC (132), and the virtual number is provided via the pBSC (132) and the pBTS (210). The call is distributed to the wireless terminal (220) (P19) (S225). On the other hand, when it is determined whether or not it is a wired subscriber number (S221), if it is not a wired subscriber number, the call is distributed to the corresponding wireless terminal via the pBSC (132) and the pBTS (210).

Next, if at least one of the wired terminal (250) and the wireless terminal (220) responds in the mobile zone (200), call processing is performed accordingly, and if not, it joins the mobile zone (200). It is determined whether the person is absent (S226). If it is determined that there is no response from the wired terminal (250) or the wireless terminal (220) in the mobile zone (200), and the mobile zone (200) is absent, the collective exchange (131) uses the PSTN (10) and the CDMA network. The wireless terminal (50a) in the public mobile communication network is called via the BTS (50) in the public mobile communication network via (20) (S227). If you are in the mobile zone (200) but there is no response, a voice guidance message such as "The subscriber is unable to receive a call, please call next" Can be transmitted (S228).
