Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system in which a wireless public network (PLMN) and a wired / wireless private network are linked to each other, and more particularly to a mobile communication system for transmitting a subscriber status of a private network to a public wireless network. The present invention relates to a method for matching a subscriber state between a public network and a private network.

Generally, the public mobile communication network and the private (or private) mobile communication network are embodied independently of each other, and it is difficult to interwork between the two networks. That is, since mobile communication systems are usually designed and implemented so as to provide only public mobile communication services or only private mobile communication services, mobile terminal subscribers registered in each network can register themselves. The service can be received only on the designated network. Therefore, mobile terminal subscribers registered in the public mobile communication network cannot receive private mobile communication services, and similarly, mobile terminal subscribers registered in the private mobile communication network receive public mobile communication services. Can not. Therefore, it is required that a mobile terminal subscriber of one mobile terminal can receive both public and private mobile communication services.

There is a public and private mobile communication system that allows one mobile terminal to receive both public and private mobile communication services due to the need for such a system development (for example, see Patent Document 1).
Korean Patent No. 365790.

よ う As shown in FIG. 1, the schematic configuration of the system disclosed in this patent application and its communication path are as follows.

Here, MS indicates a mobile station (Mobile Station), that is, a wireless terminal, MSC (Mobile Switching Center) indicates a mobile switching center, BSC (Base Station Controller) indicates a base station control station, and BTS (Base Station Transceiver). Subsystem) indicates a base station. In addition, "p" described before the name of a component means "private" and is used for convenience to distinguish it from a public network component.

Referring to FIG. 1, the public / private communication service device 12 includes a private branch exchange (PBX) 30, a private BSC (pBSC) 40, and a CM (Call Manager) 50. The private branch exchange 30 includes a switch 32 and an E1 interface 34, and the pBSC 40 includes a pCIN (private Communication Interconnection Network) 42 and a TSB (Transcoder & Selector Bank) 44. The switch 32 is connected to the PSTN / ISDN 16.

(2) The internal configurations of the private branch exchange 30 and the pBSC 40 show only the components necessary for explaining a communication path when providing a public mobile communication service and a private mobile communication service. It is assumed that the MSs 24 and 25 (Mobile Stations) are in the public / private shared cell area and are registered in the public / private communication service device 12 so as to receive the private mobile communication service. Assume that MS 22 is in a public-only cell area. Under the above assumptions, the communication path (traffic channel) A, that is, MS24, pBTS (8-k), pCIN42, TSB44 of pBSC40, switch 32, E1 interface 34, TSB44, pCIN42, pBTS (8-k), MS25 The communication path formed by the above and the communication path formed in the opposite direction are examples of a communication path when a private mobile communication service is provided. Then, the communication path (ie, traffic channel) B, ie, MS25, pBTS (8-k), pCIN42 of pBSC40, BSC (4-m) of PLMN (Public Land Mobile Network) 1, MSC (2-1), BSC (4-m), the communication path formed by the BTS (8-1) and the MS 22, and the communication path formed in the opposite direction are examples of communication paths for providing a public mobile communication service. Such communication path formation for the public mobile communication service and the private mobile communication service is performed under the control of the CM 50, which is the main control device of the public / private communication service device 12. In addition, the public / private communication service device 12 provides a wire service, an IP (Internet Protocol) terminal service, and public and private mobile communication services. The wired service is provided by the PBX 30, and the service between the IP terminals is provided by a Voice over Internet Protocol (VoIP) gate keeper (not shown), which provides public and private mobile communication services, that is, wireless calls. The service is performed under the control of the CM 50.

In addition, there is an example in which such a public and private mobile communication system is applied to a 3G network so that a private wireless internet can be provided (see Patent Document 2).
Korean Patent Application Publication No. 2003-026884.

In a system for providing a service by linking a public network and a private network as an example of this patent application, a paging signal is transmitted in a normal PLMN in the order of MSC → BSC → BTS → MS, and a mobile radio terminal The paging response message path of the machine is in the reverse order of the paging signaling process, ie, MS → BTS → BSC → MSC.

On the other hand, in a public and private communication service system such as an example of the above-mentioned patent application (Korean Patent Application No. 2001-060831), a call signal is transmitted in the order of MSC → BSC → pBSC → BTS → MS, and public and private radios are transmitted. The response path of the terminal is in the reverse order of the paging signal transmission process, ie, MS → BTS → pBSC → BSC → MSC. In this case, if the call to be passed is a public network call, the pBSC passes the call transparently and does not affect the public network incoming / outgoing processing for terminals in the public / private shared cell area. And maintain compatibility. Further, the public network BSC can be directly connected to the BTS without using pBSC. When a private network call is generated, it recognizes this and controls to perform call processing inside the private network.

However, in the public and private mobile communication system configured as described above, one private wireless terminal in the public and private shared cell area is in a call with another private terminal, or another terminal (ie, PBX) through the PBX. Is in communication with another local terminal connected to the PBX or another terminal connected to the PSTN network that can be connected through a PBX central office line), the public mobile communication network sets the corresponding local wireless terminal to When a call is made, the public network cannot recognize that the terminal is in a private call connection, and generates a call signal on the assumption that the terminal is in an idle state. For this reason, the terminal that is on the private call connection cannot answer. As a result, the PSTN cannot determine the location of the corresponding wireless terminal and attempts to make a secondary call, resulting in waste of PSTN wireless resources, and the caller can determine the correct state of the receiver. There is a problem that it cannot be recognized. Here, the secondary call does not simply mean only the number of calls, but also means that a paging zone is expanded. In other words, when the number of base stations belonging to the call area at the time of the secondary call becomes larger than that at the time of the primary call (however, in this case, each call area is not newly determined but is already determined. ), Since the call is performed on the public network, it exceeds the calling range of the corresponding private / public network.

In a high-speed wireless data system for a wireless high-speed data terminal such as 1xEV-DO (1x Evolution-Data Only), a terminal (AN: Access Node) is connected to a wireless private network to perform data communication with an arbitrary AN. Even if the arbitrary AN changes from the idle state to the busy state, the public network cannot grasp the state change of the arbitrary AN and determines that the arbitrary AN is still in the idle state. When a call connection request is issued from the public network to an arbitrary terminal in such a state, the public network recognizes the state of the arbitrary terminal as an idle state, so that the paging message is sent to the ANTS (Access). Network Transceiver System), and the ANTS performs paging non-response processing. Such paging non-response processing may cause errors in the call processing and paging message transmission procedures, and these unnecessary processing steps may increase the meaningless load on the public network.

The gatekeeper 94 is also connected to the LAN 90, and IP terminals such as a LAN phone 92, a web phone, and a PC (Personal Computer) are also connected to the LAN 90.

The pBSC 40 performs a function corresponding to the BSC in the public mobile communication system, that is, a radio link control and a handoff function. The main control unit of the pBSC 40 is built in a software block of the CM 50. pBSC40 includes pCIN42. The pCIN 42 provides a communication path with the CM 50, a communication path with the BSC (4-m) of the PLMN1, a communication path with the pBTS (8-k), and a data path between each block in the pBSC 40. That is, the pCIN 42 analyzes a message type, a sender address and a destination address included in a received message, and transmits the result to a corresponding device or processor. The E1 line connects between pCIN42 and BSC (4-m) of PLMN1 and between pCIN42 and pBTS (8-k). The TSB 44 connected to the pCIN 42 of the pBSC 40 is provided for wireless service of a private mobile communication subscriber. The TSB 44 performs a function for coordinating communication data between the PBX 30 and the pBSC 40. The INIA 46 connected to the pCIN 42 of the pBSC 40 is responsible for the private wireless data service. Also, the INIA 46 plays a role of transmitting a data packet received from an MS in the public / private shared cell area to the LAN 90 using a Point-to-Point Protocol (PPP) server and a Transmission Control Protocol / Internet Protocol (TCP / IP).

A VoIP unit 36 located in the PBX 30 and connected between the switch 32 of the PBX 30 and the LAN 90 connects an IP terminal such as a LAN phone 92 and a wired terminal (not shown) connected to the PBX 30 by the switch 32. In this case, the VoIP function is provided.

The CM 50 is connected to the pBSC 40 via the LAN 90, and performs a control function for wireless calls of public and private mobile communication services. In this case, the call service for the MS in the public mobile communication network controls the public MSC to bypass the message. In addition, the CM 50 performs an operation, a maintenance, and a maintenance function for the radio resources. However, the resource management for the pBTS (8-k) is performed by the public MSC 1 (2-1), and the CM 50 performs only the reference. The CM 50 performs a program of a processor for controlling the pBSC resources and a PLD (Program Loaded Data) loading function. However, loading to the pBTS (8-k) is performed by a public BSM (Base Station Manager) (not shown). The CM 50 controls a wired and wireless composite function. Also, since it supports an in-house radio single text service (radio SMS) function, it performs a short message service (SMS) function. In addition, the mobile terminal supports a function for registering subscribers and setting functions of a private mobile communication network, and a visitor location register (VLR) for a roaming function of an MS that has joined the private mobile communication network. ) Perform management functions.

In order to perform such functions, the CM 50 performs DCI (Data Communication Interface) 52, pBTMR (pBTS Message Router) 54, pBSC (private BSC) 56, pMSC (private Mobile Switching Center) 58, PMIC (PBX) It has software blocks including a Mobile Interface Controller (60), a Short Message Service Controller (SMC) 62, a Private Visitor Location Register (pVLR) 64, a Wireless System Manager (WSM) 66, and a LIM 68. The DCI 52 is responsible for IPC (Inter Process Communication) through HINA (High Capacity IPC Processor Assembly) as an interface module for communication between the PCIN 42 of the pBSC 40 and the CM 50. The pBTMR (pBTS Message Router) 54 is a module that is in charge of routing for all messages to be processed by the pBTS (8-k). More specifically, the pBTMR 54 refers to the internal router table, specifies a control (signal) message path for the arrival / call service of the MS (public or private), and specifies the pBTS (8-k) Specify the message path for the maintenance service of the server. Also, pBTMR54 communicates with pVLR64. The pBSC 56 controls the pBTS (8-k) as a main control unit of the pBSC 40. The pMSC 58 supports a public mobile communication network and a private mobile communication network service, and is located between the pBSC 56 and the PMIC 60 and plays a role corresponding to the MSC of the existing public mobile communication network. Also, according to an embodiment of the present invention, it basically processes various interfaces for analyzing call processing of a subscriber and other supplementary services and for interworking with the PBX 30. More specifically, the pMSC 58 analyzes a subscriber's service request, and processes a basic public mobile network service or a private mobile network service. Is determined. The interface with the pBSC 56 follows the processing procedure for the existing public mobile communication network, and the mutual interface uses the internal IPC. The PMIC 60 is a module that controls a wired and wireless combined function. The PMIC 60 is a module that is located in the public / private shared cell area and handles call control between MSs registered in the private mobile communication service, for example, the MS 24 and MS 25 shown in FIG. 1 and the wired terminal device connected to the PBX 30. is there. Unlike existing public MSCs, pMSCs 58 do not themselves play a direct switching role. This is because the pMSC 58 is a software block and does not have a switch like a public MSC. Therefore, when providing a private mobile communication service, the public / private communication service device 12 of the present invention uses the switch 32 of the PBX 30. In one embodiment of the present invention, the PMIC 60 generates a command for controlling the switch 32 of the PBX 30 according to the switch control request of the pMSC 58, and applies the generated command to a control unit (not shown) of the PBX 30. Accordingly, the control unit of the PBX 30 performs a series of switch control corresponding to the command. The SMC 62 is a module responsible for a control function for a single-text message service and an SMS web server function. The pVLR 64 is a module that manages subscriber information registered in a private mobile communication service, location registration information of a private mobile communication subscriber, and information for various function services. The WSM 66 is responsible for maintaining, maintaining, and operating all mobile communication service functions provided by the public / private communication service device 12. An operator console (not shown) is connected to the WSM 66 to interface with the operator. The LIM 68 is a module in charge of communication via the LAN 90. The LIM 68 is configured to communicate with the corresponding modules (PMIC 60, SMC 62, pVLR 64, WSM 66) via the LAN 90 through an operating system.

$ PBTS (8-k) includes a PMCC (pBTS Main Controller Card) 80, a PCC (pBTS Channel Card) 82, a TRIC (Transmit & Receive Interface Card) 84, and a PRU (private BTS Radio Unit) 86. The configuration included in the pBTS (8-k) is similar in operation to the BTS configuration in a general public mobile communication system, and thus a detailed description thereof will be omitted. In the pBTS (8-k), the PMCC 80 processes signaling messages related to call setup and system performance as a block for performing overall control of the pBTS (8-k), manages hardware and software configurations, Perform resource allocation. The PCC 82 performs band signal processing of a wireless standard. The TRIC 84 is responsible for a transmission / reception interface between the PRU 86 and the PCC 82. The PRU 86 is connected to a plurality of antennas (ANT1 to ANTn) as a radio unit.

The public / private communication service device 12 provides wired services, IP terminal services, and public and private mobile communication services. Hereinafter, the public and private mobile communication services performed by the public / private communication service device 12 will be described in detail.

(4) The public / private communication service device 12 provides not only a wireless communication service but also a multifunction service linked to a wire to the MS registered as a service in the CM 50. Services related to wireless communication services include outgoing calls, incoming calls, call transfer, call forwarding, private wireless data services, private wireless SMS, and the like. As an example of the wired / wireless multifunction service, there is a function of causing the wired terminal and the MS to simultaneously ring the incoming ring when a call is received to the wired terminal.

That such a public / private mobile communication system can provide both a public mobile communication service and a private mobile communication service means that all the messages applied to the public / private communication service apparatus 12 are analyzed and the public / private communication service is analyzed. The control (signal) message corresponding to the private mobile communication network is transmitted to the public BSC, and the control (signal) message corresponding to the private mobile communication network is routed to a module in the CM 50. The module that performs the role of routing in this way is the pBTMR 54 of the CM 50. When an event such as an outgoing call, an incoming call, a location registration, or an SMS service occurs, the pBTMR 54 analyzes the evented message and specifies a route based on the analyzed message. The pBTMR 54 is provided with a router table in which designated route information corresponding to each event is mapped. Each time a message is applied, the pBTMR 54 refers to the router table and transmits a message to a corresponding device or module.

FIG. 3 shows a configuration of a public / private communication service device of a public / private mobile communication system according to another embodiment of the present invention.

In the example of the public / private communication service device shown in FIG. 3, an asynchronous transfer mode (ATM) network is arranged between the BTS 200, the BSC _PVT 500, and the PLMNs 300 and 400, and a signal packet, a voice compression packet, A data packet is transmitted.

In addition, CMs are indicated by reference numeral 50 in FIG. 2 and exist as different server forms, but as shown in FIG. 3, BSC _PVT [private BSC (Base Station Controller)] in a card form 500.

Referring to FIG. 3, CM_1, which means a CM50 card, has software modules including pVLR 510, pMSC 520, pBSC 530, pBTMR 540, and PMIC 560 as internal components. In addition, the BSC _PVT 500 includes a pBAN (private BSC ATM Network) 550 and a TCLA (Transcode Control and Linkboard Assembly) 570, which are packet message paths.

The MS 100 located on the private (private) network comes to the PLMN 300 or 400 via the BTS 200 to make or receive a call, and the VLR of the PLMN 400 shows the state of the MS 100, that is, the busy state or idle state. It will be updated continuously. When a call is made from another station MSC (not shown) to the own station MSC of the PLMN 400, a home location register (HLR, not shown) queries the VLR for the subscriber status. In this case, if the subscriber state is "idle state", a call is routed from the other station MSC to the own station MSC of the PLMN 400, and a call occurs.

A connection path when a public network call occurs will be described in detail. In the case of an incoming call, a paging request message is transmitted from the MSC of the PLMN 400 to the BSC 300 through No. 7 signaling. The BSC 300 that has received the paging request message transmits a general paging message to the BTS 200 through the pBSC 530, and the BTS 200 generates a paging through a paging channel. However, when an incoming call occurs, the status of the MS 100 recorded in the VLR is checked, and if a call is in progress, the above-described incoming call process does not occur, and the busy process is performed inside the MSC of the PLMN 400. I do.

The connection route when a local radio call is generated will be described below.

For an incoming call, when the PBX sends a paging request message to the pBSC 530, the pBSC 530 transmits the paging message to the BTS 200, and the BTS 200 calls through the paging channel.

Conversely, in the case of an outgoing call, when the MS 100 sends an outgoing call message (origination) to the pBSC 530 through the BTS 200, the pMSC 520 occupies an available channel among the E1 channels connected between the pBSC 530 and the PBX, and then issues an allocation request ( assignment request) message to pBSC 530. PBSC 530 that has received the assignment request message transmits a channel assignment message to BTS 200. In this way, a link is established between the vocoder (not shown) of pBSC 530 and the channel of BTS 200. Next, when the MS 100 sends a service connect complete message to the pBSC 530, the pBSC 530 that has received the message notifies the pMSC 520 that the link setting has been completed as an assignment complete message. In response to the assignment complete message, the pMSC 520 sends a call message to the PBX, allowing the PBX to route the call message to the called party.

呼出 Also, a call request message sent by the BSC 300 to the BTS 200 is transmitted through the pBSC 530. At this time, the pBSC 530 analyzes the called party information included in the message to check if the call is to the private network subscriber and if the call is to the private network, and if the result of the check is a call, A reject process for rejecting the call request may be implemented.

An example of the configuration of a public / private communication service device of a public / mobile communication system to which the present invention can be applied has been described so as to facilitate understanding of an embodiment of the present invention. Those skilled in the art can understand that the present invention can be similarly applied to the apparatus according to the above-described example based on the contents of the present specification, and that the present specification has a configuration and a communication path similar to those of the above-described example. It will be appreciated that other systems and devices can be applied within the scope of the present invention.

Hereinafter, a detailed configuration according to an embodiment of the present invention will be described with reference to the public / private communication service device disclosed in FIG. 3, but this is for convenience of description and limits the scope of the present invention. It does not do. As noted, those of ordinary skill in the art will appreciate, with reference to the following detailed description, that the present invention may be applied not only to the device of FIG. 2, but also to devices having similar configurations and communication paths. Should.

FIG. 4 is a flowchart illustrating a method for processing a public network call in the public / private network of FIG. 2 or FIG. Hereinafter, description will be made with reference to FIGS.

In step 3a (BSC TRANSMITS PAGING MESSAGE TO BTS), the BSC 300 transmits a paging message to the BTS 200 in order to call the MS 100 in the public / private network shared cell area. In step 3b (pBAN TRANSMITS PAGING MESSAGE TO pBTMR), the pBAN 550 transmits the received paging message to the pBTMR 540. In the case of FIG. 2, the call message is transmitted to pBTMR 540 through pCIN42. Referring to FIGS. 3 and 4, the pBTMR 540 receives the paging message and transmits it to the BTS 200 in step 3c (pBTMR TRANSMITS PAGING MESSAGE TO BTS).

In step 3d (BTS TRANSMITS PAGING MESSAGE TO MS), the BTS 200 transmits a paging message to the MS 100. In step 3e (HAS PAGING RESPONSE MESSAGE RECEIVED FROM MS?), It is checked whether there is a response from the MS 100. As a result of the check, if there is a response, the paging response message of the MS 100 is transmitted to the pBTMR 540 through the pBAN 550 in a step 3f (BTS TRANSMITS PAGING RESPONSE MESSAGE TO pBTMR). In step 3g (pBTMR TRANSMITS PAGING RESPONSE MESSAGE TO BSC), the pBTMR 540 transmits the paging response message of the MS 100 to the BSC 300 of the public network through the pBAN 550. Then, the BSC call procedure proceeds in the 3h step (CALL PROCESS).

If there is no response from the MS 100 in the step 3e, the number of retransmissions is checked in the step 3i (IS NUMBER OF TRANSMISSION TIMES GREATER THAN 2?). If the number of retransmissions is equal to or more than a predetermined number (eg, 2), the step 3j (PAGING TERMINATION) to end the BSC call, otherwise return to step 3a to perform the paging message retransmission.

The case where the MS 100 cannot respond to the call of the public network in the public / private network will be described when there is a problem in the MS 100 itself or when the private network is currently used. In the latter case, it means that a call is being made with another subscriber terminal 700 on the premises through the private network. At this time, even if a call signal (an incoming call on the public network) occurs in the public network, the call is currently being made. MS 100 cannot respond. However, there is no way for the PLMN to know that the MS 100 is in a private call state. In other words, since the PLMN recognizes the state of the MS 100 as an idle state, the PLMN continues to call. In the illustrated example, if there is no response to the primary call, a secondary call is attempted. If the MS 100 is in a call until that time, it is impossible to respond to the call, so that the non-response process is performed. I have to do it. In this case, not only can the public network not know the position of the MS 100, but also the secondary call must be tried. In other words, public network radio resources cannot be managed efficiently.

FIG. 5 is a diagram showing a configuration of a public / private communication service device of the public / private mobile communication system according to the first embodiment of the present invention.

The first embodiment shown in FIG. 5 is an example which can be realized by the public / private communication service apparatus shown in FIG. 3, and the parts (pMSC 520, pBSC 530, PMIC 560) not directly involved are not shown.

The pBTMR 540 of the public / private communication service device according to the first embodiment of the present invention includes a first determining unit (FIRST DETERMINER) 540a, a second determining unit (SECOND DETERMINER) 540b, and a paging response message generating unit (PAGING RESPONSE MESSAGE GENERATOR) 540c. Can be included. Here, the first determination unit 540a determines whether a call is generated to the MS 100 in the public network, the second determination unit 540b determines whether the MS 100 is performing a private call, and the call response message generation unit 540c determines When the first discriminating unit 540a recognizes that a call has been made to the MS 100 in the public network, or when the second discriminating unit 540b recognizes that the MS 100 is in a private telephone call, a call response message is generated instead of the MS 100. Transmit to the public network.

The second determination unit 540b refers to a private call table 515 having status information indicating whether the MS 100 is connected to a private network and determines whether the MS 100 is on a private call. Can be.

The following describes a process of transmitting a public network call and a private network call and a process of generating a call response message for each of the calls based on the above configuration.

The PSTN call transfer process is MSC → BSC → BSC _PVT (pBTMR) → BTS → MS, and the call response message generation process is MS → BTS → BSC _PVT (pBTMR) → BSC → MSC in reverse order. Here, pBSC _PVT (pBTMR) means a BTS message router software block inside pBSC _PVT .

The private network paging call transfer process is pMSC → BSC _PVT (pBTMR) → BTS → MS, and the call response message generation process is MS → BTS → BSC _PVT (pBTMR) → pMSC.

FIG. 6 is a diagram showing an example of the structure of a private call table registered in a private network visitor location register (pVLR) according to an embodiment of the present invention.

The private call table contains a unique number (Electronic Serial Number: ESN), telephone number (Mobile Identification Number: MIN), extension number (EXTENSION NUMBER), subscriber name (SUBSCRIBER NAME), and state information (STATE) of each mobile wireless terminal. ) Is recorded. The status information indicates whether a private network can be used. This state information is recorded or deleted by the pMSC 520, but it is recorded that "private network is in use" when the private network is called, and the record is deleted when the call is released.

When generating a terminal paging response message for a paging call signal, the pBTMR 540 performs routing by referring to state information. The routing of pBTMR 540 for the PSTN call also refers to the state information. That is, if the corresponding terminal is using the private network, the terminal generates a call response message for the terminal and responds to the public network.

FIG. 7 is a diagram illustrating a structure of a call response message according to an embodiment of the present invention.

Sud_tag can display, for example, a call response message (Page Response Message: PRM) or a registration message (Registration Message: RGM) as a message tag (tag). Types of mobile_id include ESN, MIN, IMSI (International Mobile Subscriber Identity), and the like. The IMSI is stored in a SIM (Subscriber Identity Module) and is used for authentication when connecting to the system.

FIG. 8 is a flowchart illustrating a method for a private network to handle a public network call according to the first embodiment of the present invention. The call processing by the private network is roughly divided into four processes. The procedure of FIG. 8 will be described in detail with reference to FIG.

{Circle around (1)} A first step is to check whether a call is made to the MS 100 in the public network.

In step 13a (BSC TRANSMITS PAGING MESSAGE TO BTS), the BSC 300 transmits a paging message to the BTS 200 in order to call the MS 100 in the public / private network shared cell area.

Second process: When it is determined that a call is generated in the first process, and based on the private call table 515 as shown in FIG. 6, it is determined whether the MS 100 is using a private network call. It is the process of doing.

At step 13b (pBAN TRANSMITS PAGING MESSAGE TO pBTMR), the pBAN 550 transmits the received call message to the pBTMR 540. At step 13c (pBTMR REQUESTS pVLR TO ANALYZE WHETHER MS CURRENTLY USES PRIVATE NETWORK CALL), pBTMR 540 requests pVLR 510 to analyze whether the MS 100 is using the private network call.

Third step: If it is determined in the second step that a private network call is being used, a paging response message as shown in FIG. 7 is generated instead of the MS 100, and the paging response message is transmitted to the public network. It is a process.

If it is determined in step 13d (DOES MS CURRENTLY USE PRIVATE NETWORK CALL?) That the private network call is being used, the process proceeds to step 13e (pBTMR GENERATES PAGING RESPONSE MESSAGE AND TRANSMITS IT TO BSC), and pBTMR540 replaces MS100. Generates a call response message, and transmits the call response message to the BSC 300 of the public network through the pBAN 550. Then, the process proceeds to step 13f (PAGING TERMINATION) and the BSC call is terminated.

Fourth step: When it is determined in the second step that the private network call is not being used, the operation is the same as the known operation. That is, if it is determined in step 13d that the private network call is not being used, the process proceeds to step 13g (pBTMR TRANSMITS PAGING MESSAGE TO BTS), and the pBTMR 540 transmits the paging message to the BTS 200 through the pBAN 550.

FIG. 9 is a flowchart illustrating a method in which a private network notifies a public network of a state of a local MS in a public / private network shared cell area according to a second embodiment of the present invention.

In FIG. 3 described above, the transmission of the paging call of the private network is performed in the order of pMSC → BSC _PVT (pBTMR) → BTS → MS, and the local MS response is the reverse order of MS → BTS → BSC _PVT (pBTMR) → pMSC. Performed in order. In addition, the transmission of the local MS state by the private network is performed in the order of pBSC (pBTMR) → BSC → MSC. Such an operation will be specifically described with reference to FIG.

Assume that the MS 100 is called from another subscriber terminal 700 in the premises, and a situation in which the state of the MS 100 is notified to the public network at this time will be described.

First step: When a private exchange (PBX) sends a paging request message for paging the MS 100 in the public / private network shared cell area, the pMSC 520 calls the MS 100 in step 5a (pMSC GENERATES PAGING MESSAGE). Occurs, and the pBSC 530 transmits this to the BTS 200 in step 5b (pBSC TRANSMITS PAGING MESSAGE TO BTS). In step 5c (BTS TRANSMITS PAGING MESSAGE TO MS), the BTS 200 transmits a paging message to the MS 100.

(2) Second process: The MS 100, which has received the paging message in step 5d (MS TRANSMITS ACKNOWLEDGEMENT MESSAGE TO BTS), generates an acknowledgment message (ACK) and transmits it to the BTS 200.

{Circle around (3)} The BTS 200 receives the response message through the 5e step (HAS BTS RECEIVED ACKNOWLEDGEMENT MESSAGE?) And the 5f step (BTS TRANSMITS ACKNOWLEDGEMENT MESSAGE TO pBSC) and transmits it to the pBSC 530 through the pBAN 550. In a 5g step (pBSC TRANSMITS ACKNOWLEDGEMENT MESSAGE TO pMSC), the pBSC 530 transmits this to the pMSC 520. In step 5h (pMSC TRANSMITS STATE MESSAGE TO pBSC), when the pMSC 520 detects the reception of the response message, it forms a communication path, generates a state message for informing the state of the MS 100 (during communication), and transmits it to the pBSC 530. In step 5i (pBSC TRANSMITS STATE MESSAGE TO BSC), the pBSC 530 transmits the status message to the public network BSC 300 through the pBAN 550, and in step 5j (BSC TRANSMITS STATE MESSAGE TO MSC), the BSC 300 transmits the status message to the MSC 400. At step 5k (MSC RECORDS STATE OF MS IN VLR), the MSC 400 records the state of the MS 100 (during a call) in the VLR according to the state message.

Fourth process: If it is determined in the third process that a response message has been received, a process for responding to no response is performed. Specifically, if the pMSC 520 does not detect the reception of the response message in the step 5e, a predetermined number of times (or a predetermined number of times) such as the step 51 (N TIMES?) And the step 5m (N ← N + 1) are performed. (Time) Retry the call.

FIG. 10 is a flowchart illustrating a method for transmitting a terminal status message to a mobile switching center (MSC) when a private network terminates a terminal call according to a second embodiment of the present invention.

過程 First process: In step 6a (pMSC GENERATES CALL TERMINATION MESSAGE TO TRANSMIT IT TO pBSC), the pMSC 520 generates a call termination message to the MS 100 in the public / private network shared cell area.

Second process: The pBSC 530 receives the call termination message in step 6b (pBSC GENERATES MS STATE MESSAGE TO TRANSMIT IT TO BSC), generates a terminal status message (idle status), and transmits it to the BSC 300 of the public network through the pBAN 550.

Third process: When the BSC 300 transmits a status message to the MSC 400 in step 6c (BSC TRANSMITS MS STATE MESSAGE TO MSC), the MSC 400 transmits the status message to the VLR in response to the status message in step 6d (MSC RECORDS STATE OF MS IN VLR). (Idle state) is recorded.

FIG. 11 is a diagram illustrating a structure of a new message when a new message is generated for subscriber matching according to an exemplary embodiment of the present invention.

A message field constituting one arbitrary message basically has a message_header (message header: HEADER) of 50 bytes, a message_length of 2 bytes (message length: LENGTH), and 4 bytes. Message_ID (message_ID (identification): ID). The message_header is an area for recording a destination / source address and the like, the message_length is an area for storing the length of the message, and the message_id is a message type. This is an area for recording.

メ ッ セ ー ジ By recording busy (LOCAL_BUSY_MSG_TYPE) or idle state (LOCAL_IDLE_MSG_TYPE) in the message_id area, the message can be used for subscriber matching.

FIG. 12 is a diagram illustrating a structure in which a sub-ID and a sub-type are added to an existing message for subscriber matching according to an exemplary embodiment of the present invention.

This shows a mode in which an arbitrary message further has a message_sub_ID (message_sub_ID: SUB_ID) in the basic area described in FIG. The message_sub_id is composed of 4 bytes and is an area for recording a subtype included in the message type.

基本 By recording the busy (LOCAL_BUSY_MSG_TYPE) or idle state (LOCAL_IDLE_MSG_TYPE) in the message_sub_idy area, the basic message can be used for subscriber matching. FIG. 13 shows a specific example.

FIG. 13 is a diagram illustrating a structure in which a sub-ID and a sub-type are added to a location registration message for subscriber matching according to an embodiment of the present invention.

The location registration message is an area for recording the basic area described with reference to FIGS. 11 and 12, a 1-byte registration type, a 1-byte slot cycle index (slot_cycle_index), and a terminal version. including. By recording busy (LOCAL_BUSY_REG_TYPE) or idle (LOCAL_IDLE_REG_TYPE) in the registration type, the location registration message can be used for subscriber matching. Also, the slot cycle index indicates a cycle in which the terminal searches for a paging channel message. For example, a slot cycle index of 0 indicates 1.28 seconds, 1 indicates 2.56 seconds, and 2 indicates 5.12 seconds. In the case of the terminal version, 1 indicates IS-95, 2 indicates IS-95-A, and 3 indicates TSB 74.

　 FIG. 14 shows a configuration diagram of a public / private mobile communication network when an embodiment of the present invention is applied to a wireless high-speed data system for 1xEV-DO terminals. A mobile communication network is a wireless network that can use both a public network (or PLMN) and a private network. Hereinafter, the network configuration of the wireless high-speed data system according to the embodiment of the present invention and the functions and operations according to each configuration will be described with reference to FIG. As in FIG. 1, in FIG. 14 as well, a node of a private network or a node commonly used for the wireless private network and the PLMN is described as a private network node by writing a small letter “p”.

無線 Wireless high-speed data terminals (AN: Access Nodes) 11 and 21 shown in FIG. 14 are terminals used in a general wireless high-speed data system. It is assumed that AN 11 of the terminals 11 and 21 is a subscriber receiving the wireless private network service, and another terminal 21 is a subscriber receiving the PLMN service. Also, private access network transceiver systems (pANTS) 101 and 102 shown in FIG. 14 have predetermined wireless service areas 10 and 20, respectively, and when a terminal enters the wireless area, a session (pANTS) Session), and performs an operation necessary for allocating a necessary UATI (Unicast Access Terminal Identifier) to the corresponding terminal. Also, when the AN has a call reception or the AN has a call transmission, the pANTSs 101 and 102 perform an operation according to the call reception. The pANTSs 101 and 102 are connected to the hub 110.

The hub 110 is connected to each node in the wireless private network and another node of the PLMN or another hub for connecting to another node. FIG. 14 shows a configuration connected to another hub 120 when connected to the outside of the wireless private network. Further, the hub 110 is connected to a private packet data serving node (pPDSN) 111 that can be used only by the AN of the wireless private network, and a private access network commonly used by the wireless private network and the PLMN. It is connected to a controller (pANC: private Access Network Controller) 112 and a private authentication system (pAN_AAA: private Access Network Authentication Accounting Authorization) 113 used only in a wireless private network to relay data. Here, the pAN_AAA 113 may be configured to be used commonly by the wireless private network and the PLMN.

Ｐ The pANC 112 of the wireless private network controls session setting for the ANs 11 and 21, assignment of UATI, and authentication of the AN through the pAN_AAA 113. Also, the pANC 112 performs a routing by providing a service to the AN or pPDSN 111 in the wireless private network and a service to the outside of the private network. Further, the pANC 112 performs setting and updating of a session for authentication of the AN 11 or AN 21, control for UATI assignment, traffic control according to call setting, various signaling controls, and the like. For example, the pANC 112 transmits a paging signal to the AN, allocates or updates session information to a DLR (Data Location Register) 121, stores location information, and allocates a UATI for the DLR 121.

The other hub 120 is connected to the AN_AAA 122, the ANC 123, the PDSN 124, and the DLR 121 storing information of the AN, and relays data between the nodes. Further, an ANTS of PLMN can be connected to the hub 120, but this is not shown in FIG.

The PDSN 124 is connected to another packet service node or the pPDSN 111 through the Internet 130. The ANC 123 of the public network is a general ANC of a wireless high-speed data system, and the AN_AAA 122 is also a general AN_AAA of a wireless high-speed data system.

The DLR 121 stores the AN information and the AN location information on the AN of the wireless high-speed data system, and provides the AN information when the session of the corresponding terminal is updated. Also, the DLR 121 stores information on ANs included in a general PLMN. General PLMN AN information includes AN state information, user information, service class information, and the like. Further, the DLR 121 further includes AN information of the wireless private network according to an embodiment of the present invention. At this time, the information provided by the DLR 121 can be classified into a case where the AN receives a service provided only by the wireless private network and a case where the AN receives a service simultaneously by the wireless private network and the PLMN. In one embodiment of the present invention, an AN that receives all services in a wireless private network and a PLMN will be described. In this case, the DLR 121 has information on the AN of the wireless private network and the same information that is necessary for the AN of the PLMN, and further has information on the wireless private network. Here, the information related to the wireless private network further includes a service area, for example, service ANC or sector information, service time information, service type information, and the like. When the DLR 121 assigns the UATI to the AN, it may be configured to assign it according to a special rule.

Further, when the AN of the private wireless network receives a service, it may be configured to further provide an identifier capable of distinguishing between the connection to the wireless private network and the connection to the public network, and transmit the identifier.

PANTS101, 102, pANC112, ANC123, DLR121, pPDSN111 and PDSN124 can be configured on an IP basis. Generally, the connection between the pANTS and the pANC 112 and the ANC 123 and the connection between the DLR and the PDSN are based on an ATM. However, such a configuration causes an increase in cost. Therefore, the cost can be effectively reduced by using the IP base. When the pANTSs 101 and 102, the pANC 112, the ANC 123, the DLR 121, the pPDSN 111, and the PDSN 124 are configured based on the IP, the communication between each board or the processor in each node is configured to perform the IPC (Inter Process Communication) communication. I do. In addition, an IP for internal use is assigned to the internal processor or board of each node. When the node is located inside a CO (Center Office) such as a predetermined telephone station or control station, an internal IP can be allocated and used. A node located far from the CO is assigned a fixed IP. In this way, shortage of IP addresses can be prevented.

An interface between the pANTSs 101 and 102 and the pANCs 112 and 123 can use an ADSL modem, a cable modem, or the like. Also, since pAN_AAA113, AN_AAA122, pPDSN111 and PDSN124 are configured to use the IP system from the beginning, there is no problem.

In the wireless high-speed data communication system having the above-described configuration, a message flow according to a process in which a call is originated for communication in a wireless private network according to an embodiment of the present invention will be described with reference to FIG. FIG. 15 is a diagram illustrating a call processing process for managing state information of a wireless high-speed data terminal according to an embodiment of the present invention.

Referring to FIG. 15, when the private wireless network AN 11 requests the 1xEV-DO service of a call in step 201 (CALL CONNECTION REQUEST MESSAGE TO AN WITH IN PRIVATE NETWORK), that is, the defined air interface protocol Based on the (air interface protocol) standard, a call connection request message including a UATI and a destination address of a transmission target is transmitted to the pANTS101. That is, according to an embodiment of the present invention, the AN 11 transmits a call connection request message with a terminal connected to the private network. When receiving the call connection request message, the pANTS 101 transmits the call connection request message to the hub 110 after the IP communication processing. The hub 110 transmits the received call connection request message to the pANC 112. When the pANC 112 of the private network receives the call connection request message, it transmits the subscriber information request message of the called side AN to the DLR 121 in step 203 (SUBSCRIBER INFORMATION REQUEST MESSAGE). When the DLR 121 receives the subscriber information request message, the DLR 121 queries the corresponding subscriber information and transmits a subscriber information response message including the subscriber information to the pANC 112 in step 205 (SUBSCRIBER INFORMATION RESPONSE MESSAGE). The pANC 112 determines the location of the called terminal in the private network based on the subscriber information included in the received subscriber information response message, and sets up a call in step 207 (CALL SETUP). Accordingly, the AN 11 of the wireless private network receives the wireless high-speed data service in step 209 (HIGH-SPEED WIRELESS DATA SERVICE). In the case where the receiving AN is a terminal in a private network, the terminal status information of the subscriber information of the DLR 121 is not updated even if a call is set up in the related art, but according to an embodiment of the present invention, The status information of the AN is updated as follows.

The pANC 112 transmits a state information update request message including state information of the originating AN 11 and the destination AN to the DLR 121 in step 211 (STATE INFORMATION UPDATE REQUEST MESSAGE) after step 207. That is, a message requesting that the state information of the originating AN 11 and the receiving AN be updated to a busy state is transmitted. Upon receiving the state information update request message in step 213 (UPDATE STATE INFORMATION OF SUBSCRIBERS TO BUSY STATE INFORMATION), the DLR 121 searches the subscriber information and updates the state information of the AN's subscriber information to a busy state.

Thereafter, when the PDSN 124 receives a call connection request message requesting a call connection with one of the ANs receiving wireless high-speed data communication from any of the connected ANs, the PDSN 124 proceeds to step 215 (CALL CONNECTION REQUEST MESSAGE). ), The call connection request message is transmitted to the ANC 123 of the public network. In one embodiment of the present invention, it is assumed that an AN requesting a call connection through the PDSN 124 requests a call connection with the AN 11 to facilitate understanding. When the AN 11 requests a call connection, the same process as described below is performed. The ANC 123 of the public network transmits a subscriber information request message requesting the subscriber information of the AN 11 to the DLR 121 in step 217 (SUBSCRIBER INFORMATION REQUEST MESSAGE). Upon receiving the subscriber information request message in step 219 (SUBSCRIBER INFORMATION RESPONSE MESSAGE), the DLR 121 searches the subscriber information of the AN 11 and transmits a subscriber information response message including the subscriber information to the ANC 123. When the ANC 123 receives the subscriber information response message in step 221 (BUSY STATE INFORMATION), the ANC 123 analyzes the subscriber information and recognizes that the state of the AN 11 is busy, and accordingly, determines that the AN 11 is busy. Is transmitted to the PDSN 124.

On the other hand, upon completion of the wireless high-speed data communication service, the AN 11 transmits a call release request message to the pANC 112 of the wireless private network through the pANTS 101 in step 223 (CALL RELEASE REQUEST MESSAGE). Upon receiving the call release request message, the pANC 112 releases the call of the AN 11 in step 225 (CALL RELEASE), and proceeds to step 227 (STATE INFORMATION UPDATE REQUEST MESSAGE). In step 227, the pANC 112 transmits a subscriber status information message indicating that the AN 11 has become idle to the DLR 121. The DLR 121 updates the state information of the AN 11 to an idle state in step 229 (UPDATE STATE INFORMATION OF SUBSCRIBERS TO IDLE STATE INFORMATION).

As described above, even if communication is performed in the wireless private network, the pANC 112 updates the subscriber information of the DLR 121 according to the state of the terminal according to the present invention.
