Description

  The present invention relates to a wired / wireless telephone link service system, and more particularly to a wired / wireless telephone link service operation method for providing mobility to a subscriber who uses 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 for explaining a conventional wired telephone service and a mobile communication telephone service. Referring to FIG. 1, in the wired telephone service, a public telephone network (PSTN) (10) is used to connect a telephone station (70) to a wired telephone terminal (80) via a telephone line.

  Thus, 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, cordless telephones that perform wireless communication using such a wired telephone terminal body and a 900 MHz wireless band have been developed and used, but there are many restrictions on mobility compared to mobile communication terminals that use mobile communication services. There is a problem to receive.

  On the other hand, the mobile communication telephone service is provided with mobility using a public land mobile network (hereinafter referred to as PLMN).

  PLMN consists of a mobile switching center (MSC) (30), 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) collectively represents a radio environment in charge of mobile communication services in another area.

MSC (30) performs control to connect a plurality of BSC linked to self (40) and PSTN (Public Switch Telephone Network) ( 10) or other MSC in PLMN (20) (not shown).

  The BSC (40) performs radio link control, handoff function, etc., and the BTS (50) configures a radio communication path with a radio terminal belonging to its own communication service area, that is, its own cell area. Perform functions to manage

  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 that the corresponding MSC is in charge of among a plurality of MSCs, etc. This database temporarily stores MS information. If the MS moves to a cell area managed by another MSC, the information stored in the corresponding VLR is deleted.

  In this way, even in the case of a mobile communication telephone service using PLMN, each service is independent and interconnected because it is not linked to 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 regardless of the area limited to the premises, etc., but this uses a mobile communication service system, and there is no additional charge within the set area. It was not possible to communicate wirelessly.

  In other words, in order to make a call between a wired telephone service terminal using a wired telephone service and a mobile communication service subscriber's mobile communication terminal, the respective exchanges are connected via a public network, and then the call is connected to the other terminal. there were.

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

In addition, when a subscriber receives a wired telephone service and a mobile communication service at the same time, the use of the communication service has an inconvenience because it is necessary to pay the respective communication charges.

When there subscriber receives the provision of the mobile communication service wired phone service at the same time, and others know only one of them the telephone number, when calling the appropriate terminal, if it can not respond with the terminal, Although the subscriber has another terminal, there is a problem that the call cannot be connected with the subscriber.

Of course, if there is a call to an arbitrary terminal using the call conversion service, only has as another terminal specified is invoked, which is served only if a preset If the incoming call conversion service is set, only the terminal designated for incoming call conversion is called out of the two terminals.

Accordingly, the present invention has been devised to solve the above problems, and a wired / wireless telephone link service system and a wired / wireless telephone link service operation method for providing mobility to a conventional wired telephone service subscriber. The purpose is to provide.

Another object of the present invention is to provide a wired / wireless telephone link service system and a wired / wireless telephone link service that can reduce the burden on the duality of billing when a subscriber uses a wired telephone service and a mobile communication service at the same time. The purpose is to provide a method of operation.

Another object of the present invention is that when a subscriber uses a wired telephone service and a mobile communication service at the same time, the subscriber has a case where another person calls one of the telephone numbers. It is an object to provide a wired / wireless telephone link service system and a wired / wireless telephone link service operating method that allow a call to be answered at any terminal.

According to one aspect of the present invention for achieving the above object, in a wired / wireless telephone linked service system, a private base station (pBTS) is connected to a public switched telephone network (PSTN). Information on virtual wired telephone numbers assigned to each of a plurality of mobile communication terminals provided in a mobile zone (Mobile Zone) which is a management area of (System) is stored in a memory, and the virtual wired telephone numbers are used to store the information A collective exchange that provides a public wired telephone service to a mobile communication terminal and also provides a wired telephone service to a wired telephone terminal provided outside the mobile zone, a public land mobile network (PLMN), and a private base station Public mobile communication service that uses individual mobile phone numbers (MIN) for mobile communication terminals. Information associated with the individual telephone number (MIN) of the mobile communication terminal and the virtual wired telephone number is stored in a memory, and this information is used to store the individual telephone number (MIN) and the virtual telephone number. wired telephone number in conjunction private base station controller to provide a private mobile communication service that connects the mobile communication terminal of the internal mobile zone wired telephone network: and (pBSC Private base station controller), wherein the private base When the station controller receives a call origination service request from a mobile communication terminal in the mobile zone, the station controller distinguishes whether the mobile communication terminal requests a private mobile communication service or a public mobile communication service. In the case where the private mobile communication service is requested, the caller information (CID: Caller ID) is given to the mobile communication terminal. A wired / wireless telephone interlocking service system is provided in which the virtual wired telephone number is changed and transmitted to the collective exchange, and the collective exchange calls an incoming terminal .
Further, in the wired / wireless telephone link service method, a group switch connected to a public wired telephone network assigns a virtual wired telephone number to each of a plurality of mobile communication terminals provided in a mobile zone which is a management area of a private base station. The private base station controller connected to the public mobile communication network and the private base station corresponds to the individual telephone number (MIN) of the mobile communication terminal and the virtual wired telephone number. Storing the attached information in a memory; providing a public wired telephone service to a wired telephone terminal provided inside and outside the mobile zone by the collective switch; and Providing a public mobile communication service using the individual telephone number (MIN) and the individual telephone number (MIN) stored in the memory Using the information of the virtual wired telephone number associated with the private wired telephone number, the individual telephone number (MIN) and the virtual wired telephone number are linked to connect the mobile communication terminal in the mobile zone to the public wired telephone network. Providing a mobile communication service, and when the private base station controller receives an outgoing service request from a mobile communication terminal in the mobile zone, the mobile communication terminal is a private mobile communication service or a public mobile communication service. The identifier for distinguishing which one of the services is requested is confirmed, and when the private mobile communication service is requested, caller information (CID: Caller ID) is given to the mobile network communication terminal. has been changed to a virtual wired number is transmitted to the population exchange, wired telephone interlocking Sir said population exchange is characterized in that it calls the called terminal To provide a scan method.

  According to the present invention, when a subscriber subscribes to a wired telephone service using a wired / wireless interlocking device, not only the existing wired telephone service but also the wired telephone terminal is called via a designated wireless terminal when calling. The ability to receive calls simultaneously within a private mobile communications network operated by a wireless interlocking device provides mobility for wired telephone services.

In addition, by operating a virtual wired telephone number in the form of a general wired telephone service telephone number, it is possible to receive a call that an external subscriber has called with a wired telephone number via his / her wireless terminal. When calling, the caller ID is sent as a virtual wired telephone number, so that the subscriber actually has the same effect as having a wired telephone terminal when viewed from an external subscriber even when no wired telephone terminal is installed. Can be provided. Also, when an external subscriber or the like makes a call to the subscriber's wireless terminal, he / she can receive the telephone service at the charge 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, the internal subscriber may not be charged, thereby reducing the burden on the duality of charging.

  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 the term “wireless phone” is used for convenience. Therefore, here, the wireless terminal is limited to the mobile communication terminal.

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

  Referring to FIG. 2, the wired / wireless telephone linked service system according to an embodiment of the present invention is connected to the public telephone network (10) and the base station controller (40) of the public mobile communication network and registered with the service. A wired / wireless interlocking device (100) that provides subscribers with a wired telephone service and a public / private mobile communication service, and a private mobile communication service within the communication area connected to the wired / wireless interlocking device (100). Private base station equipment (private BTS, hereinafter referred to as pBTS) (210) that provides a wireless environment, and wireless terminals (220, 240, 260) that provide public / private mobile communication services via pBTS (210) And wired telephone service terminals (230, 250, 270) to which a wired telephone service is provided.

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

  The wired / wireless link apparatus (100) includes a function of a wired telephone station that performs a wired telephone service. In other words, an individual telephone number (for example, 02-XXX-YYYY) is given to a subscriber who is provided with an exchange device (not shown) for the wired telephone service and is registered in the wired telephone service, and is installed in the subscriber's home. Wired telephone service is provided through telephone lines connected to the wired telephone service terminals (230, 250, 270).

  The wired telephone service corresponds to, for example, a general wired telephone service provided to subscribers via a telephone station in Korean communication, and various additional services such as an Internet service including a basic outgoing service and incoming call service. Can be true.

  Moreover, the xDSL subscriber line service which has been spreading rapidly recently can also be applied.

  As a result, the wired / wireless interlocking device (100) can be implemented in conjunction with an exchange provided in a conventional telephone office, and can be implemented by improving the exchange provided in the telephone office. It can also be embodied in a private exchange network having a private exchange.

The wired telephone service terminals that can receive the wired telephone service from the wired / wireless interlocking device (100) include general wired telephones (230, 250), personal computers (270), and various types for home networks. Equipment (not shown), etc. can correspond. The general wired telephones (230, 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 interlocking device (100) operates a private mobile communication network in a limited communication area (200).

  Here, the private mobile communication network is intended to distinguish it from a public mobile communication network that is generally operated nationwide by various mobile communication carriers (for example, 01X operators in Korea). This means a mobile communication service for providing a high-quality service to its own subscribers or the like in a limited area that the base station can accept by providing a limited number of base stations.

  Therefore, 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 (e.g. ) Can be implemented by providing a mobile communication device.

  For this purpose, the wired / wireless interlocking device (100) is provided with a device (not shown) for mobile communication service, and an individual telephone number (Mobile Identifier Number: MIN) (for example, for subscribers registered in the mobile communication telephone service) 02-CCC-DDDD) to provide mobile communication telephone service via pBTS (210) to wireless terminals (230, 250, 270) located in their private communication area.

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 public mobile communication network service and use a general public mobile communication network. Since it is provided, a separate mobile communication terminal telephone number (MIN) (for example, 016-AAA-BBBB) is given by the corresponding mobile communication carrier.

At this time, the wired telephone number format (for example, 02-CCC-DDDD) is used as the individual telephone number assigned to the wireless terminal registered in the mobile communication service by the wired / wireless interlocking device (100). The use of the wired telephone number format is to make an external subscriber using the wired telephone service recognize as a general wired telephone service subscriber when calling the corresponding subscriber via the PSTN (10). As a result, the external subscriber can call a general wired telephone service subscriber when calling the corresponding subscriber, and the charge is also settled at the charge 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 form of a general wired telephone number. This is a telephone number generated only by software in the wired / wireless interlocking device (100). It means a virtual telephone number that is not a telephone number connected to a wired telephone terminal.

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

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

  Next, subscribers who use 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 assigned by the public mobile communication network, and the other is a telephone number assigned by the wired / wireless interlocking device (100). The wired / wireless link apparatus (100) stores information on the telephone number assigned to the subscriber and the telephone number assigned by the public mobile communication network operator in a database.

  Finally, it is a subscriber who uses both wired telephone service and 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 the telephone line provided up 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 assigned to the wired telephone terminal, the other is a telephone number assigned to the wireless terminal in the public mobile communication network, and the other is a wired / wireless interlocking device ( 100) is a virtual telephone number assigned to the wireless terminal. Thereby, the wired / wireless interlocking device (100) stores the above three types of telephone number information in a database for the corresponding subscriber.

  The wired / wireless link apparatus (100) can provide differentiated services to each subscriber.

The subscriber using only general wired phone service providing outgoing call service by wireline telephone service generally over a telephone line.

If a subscriber using only the mobile communication services have a calling request through the wireless terminal, sent in caller ID from the corresponding wireless terminal (Caller ID) is assigned a public mobile communication network MIN (016-AAA-BBBB) As a result, the caller ID converted to the virtual telephone number (02-CCC-DDDD) is transmitted via the PSTN (10). Thereby, an external subscriber receives a virtual telephone number as caller ID information for the corresponding call.

  A subscriber who uses both a wired telephone service and a mobile communication service can be provided with a multiple incoming call function. The multiple incoming call function is to transmit a ring signal simultaneously to the wired telephone service terminal and the 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 The virtual telephone number registered in the subscriber who has is retrieved and the corresponding wireless terminal is called through pBST (210). If there is no response from the corresponding wireless terminal even though the corresponding wireless terminal is called through pBST (210), it is determined that the wireless terminal is not in the private communication service area, and public mobile communication is performed via the public mobile communication network. Call the corresponding wireless terminal via 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 calls and multiple incoming calls are set for an arbitrary telephone number, you must have a database for the virtual telephone number by wired telephone number and the virtual telephone number by telephone number in the public mobile communication network. I must.

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

That is, 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 received , the wired / wireless interlocking device (100) uses the pBTS (210). Mobile communication services are provided to the wireless terminals (220, 240, 260).

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

  Also, the wired / wireless link device (100) can communicate via the PSTN (10) if the wireless terminal (220, 240, 260) registered for service wishes to talk to a public network subscriber (11) that is not an extension subscriber. Then, the communication is made possible by setting a communication channel with the public network subscriber.

  On the other hand, the pBTS (210) is a wireless terminal (220, 240) registered for use of a private mobile communication service in the wired / wireless interlocking device (100) within its own communication area (hereinafter referred to as a mobile zone) (200). 260) provides a public / private mobile communication service by configuring a wireless communication channel and managing wireless resources when requesting the setting of the wireless communication channel.

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

In addition, the wireless terminal (220, 240, 260) is connected to another wireless terminal (220, 240, 260) that is registered for use of the private mobile communication service via the wired / wireless link device (100), or a wired telephone service. It will be possible to receive a call service with terminals (230, 250, 270).

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

  In order to operate the wired / wireless service system configured as described above, the following procedure is necessary.

First, a subscriber registration application for a wired / wireless service is received from an arbitrary extension subscriber. The information required at the time of the subscriber registration application includes subscriber's personal information, settlement information, telephone number of the wired terminal, individual telephone number of the mobile communication terminal, virtual wired telephone number of the mobile communication terminal, and the like . Here, the social position information name, address, such as resident registration number is applicable.

  By applying for subscriber registration, a wired telephone number is assigned to one or more wired terminals, public / private mobile communication terminals, etc., and wired / wireless service registration is performed for each extension subscriber.

  When registering a wired / wireless service, the wired telephone number assigned to the wired terminal that constitutes the extension network, the wired telephone number assigned to the public / private mobile communication terminal, and the public / private mobile communication terminal are connected to the public mobile communication. The 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, the first identification information indicating whether the wired telephone number is a wired telephone number connected to the terminal or a wired telephone number not connected to the terminal, and the wired telephone number is A process of registering in the database the second identification information indicating whether or not to use the simultaneous incoming service and the wired telephone number of the public / private mobile communication terminal called by the simultaneous incoming function is performed. After completing this registration process, if any wired phone number is called, if there is a public / private mobile communication terminal that is called simultaneously with the wired phone number, calling the wired terminal corresponding to the wired phone number Call the public / private mobile communication terminal via the mobile communication network. It is possible to perform a procedure for charging for use of the wired / wireless service for each extension subscriber. At the time of billing, an extension charge rate can be applied when a private mobile communication network is used, and an external charge rate can be applied when a public mobile communication network is used.

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

  Referring to FIG. 3, the wired / wireless link apparatus (100) includes a wired exchange (111), a mobile gateway (MobileG / W) (112), and a pBSC (113).

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

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

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

  That is, when the wired switch (111) assigns a wired telephone number to an arbitrary subscriber for the wired telephone service, the SLC interface to which the wired telephone number is assigned is called to the subscriber's wired telephone terminal (250). The SLC interface is temporarily connected to the office line interface of the mobile gateway 112 and sent to the mobile gateway 112 without being directly connected via the line.

  The mobile gateway (112) assigns the line of the wired telephone service extension subscriber of the wired exchange (111) received via the office line interface to its own SLC interface and then reaches the corresponding wired telephone terminal (250) via the telephone line. Connect.

  As a result, the wired telephone terminal (250) is connected to the SLC interface of the wired switch (111) via the SLC interface of the mobile gateway (112) and the office line interface. Accordingly, when the wired telephone terminal (250) hooks off the handset for a call, the wired telephone terminal (250) listens to the dial tone provided by the wired telephone exchange (111).

  In addition, the wired exchange (111) can assign a wired telephone number to each subscriber within a range that the SLC interface can accept by providing a wired telephone service to its extension subscriber. The wired exchange (111) can 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 includes a commonly used wired telephone number connected to the terminal by the wired telephone terminal (250) and a virtual wired telephone number assigned only to the telephone number without being connected to 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 classified. This is because the wired exchange (111) assigns a telephone number for any extension subscriber to the SLC interface and sends it to the local interface of the mobile gateway (112) via the SLC interface. Connecting or not connecting the wired telephone terminal (250) to the end of the specified telephone number is a matter involved in the mobile gateway (112), and the wired switch (111) is simply used as the extension subscriber information. Just manage.

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

  That is, the line that the mobile gateway (112) allocates by connecting to 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 number assigned from the wired exchange (111). The database 112b can be implemented in the memory 112a. That is, as shown in FIG. 4, the database stores information indicating whether each telephone number is a virtual telephone number and information indicating whether it is registered in the multiple incoming service.

For example, if 0 is set in the field indicating whether or not a virtual phone is available, it is a wired telephone number connected to a wired terminal, 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 0 is set in the field indicating whether multiple incoming calls are allowed, this means that the service is limited to existing services that call the wired telephone terminal corresponding to the corresponding wired telephone number. For example, it indicates that the service is registered in a service that can perform multiple incoming calls.

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

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

On the other hand, mobile gateway (112) is transmitted, when receiving a call service request by any wireless terminal from pBSC (113), the caller ID of the wireless terminal received from the calling number and the corresponding wireless terminal to the wired exchange (111) To do.

At this time, the caller ID of the wireless terminal transmitted to the wired exchange (111) is a 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 corresponding transmission 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 be called 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.

pBSC (113) controls pBTS (210) and analyzes subscriber call processing and other supplementary services to support public and private mobile network services and mobile gateway (112) Process various interfaces for linking.

For this reason, in order to receive provision of a private mobile communication service , the subscriber of the wireless terminal adds identification information set in advance to the calling telephone number for distinguishing the service.

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

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

As an example, if the user enters the phone number “# 212” via the wireless terminal, pBSC (113) will contain the identifier “#” that it wishes to use the private mobile communication service, so private mobile It is determined that it is desired to use the communication service, and a call request signal including the telephone number “212” is transmitted to the mobile gateway 112 so that a call can be made with the extension subscriber having the extension number “212”. .

Also, if the user enters the telephone number “# 02-212-8866”, pBSC (113) contains the identifier “#” that the private mobile communication service is desired to use. The mobile phone (112) transmits a call request signal including the telephone number "02-212-8866" to the mobile gateway (112) and makes a call through the public telephone network via the wired switch (111). Make a call with a public telephone network subscriber with the number "02-212-8866".

Also, if the user enters the telephone number “# 016-212-8866”, pBSC (113) contains the identifier “#” that the private mobile communication service is desired to use. The mobile phone (112) transmits a call request signal including the telephone number "016-212-8866" to the mobile gateway (112), and the public through the public telephone network via the wired switch (111). It is possible to make a call with a public mobile communication service subscriber of “016-212-8866” via the mobile communication network.

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

  That is, the database (113b) stores information indicating whether or not 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 is stored.

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

  Therefore, even 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 call service via the pBTS (210), it can be roughly divided into two cases.

First, there may be a case where a call is requested using a private mobile communication service. In such a case, by pBTS (210) MIN number assigned to a public mobile communication network caller ID transmitted from is sent, virtual wired phone number caller ID by referring to the database shown in FIG. 5 And is sent 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 sent to the caller ID transmitted from pBTS (210), so that the caller ID remains as it is. It is transmitted to BSC (40) of the communication network.

  The pBSC (113) manages the database (113c) for the multiple incoming service in the memory (113a). In other words, a wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming calls are set in a wired telephone terminal installed in the home and the virtual wired terminal assigned to the wireless terminal that is called at the same time when the corresponding wired telephone number is called It manages a database (113c) for telephone numbers.

  As a result, when inquiring about the virtual wired telephone number that has been set to the wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming calls have been set in the mobile gateway (112), the corresponding wired telephone in the database (113c) A number (eg, 02-XXX-YYYY) can be retrieved to find the virtual telephone number (02-CCC-DDDD) linked to the wired telephone number and respond 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 service. In the database (112b) built in the mobile gateway (112), information on whether or not an arbitrary wired telephone number has been received is stored, and information on the virtual wired telephone number assigned to each wireless terminal is stored. .

  On the other hand, the database (113c) built in the pBSC (113) 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 multiple incoming calls to that wired telephone number. Is saved. The database 113b and the database 113c may be implemented as one database.

  In the wired / wireless interlocking device (100) configured in this way, not only a wired telephone service for a wired telephone terminal but also an incoming call to a designated wireless terminal is possible when a virtual wired telephone is called. In addition, when calling a wired telephone, the mobile gateway (112) can make a simultaneous call with 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 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) corresponding to the virtual wired telephone number.

  If an incoming call response is received at the wireless terminal, the calling call is connected. If no incoming response is received, the service is terminated by the wired telephone service procedure.

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

  The incoming call procedure will be described with reference to the incoming call paths (P1, P2) shown in FIG.

  When any subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the wired exchange (111) is called 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, the 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 number in the database 112b shown in FIG. 4 that the mobile gateway 112 has (S5). If it is determined that the number is not a multiple incoming call number, the call is distributed to the wired subscribers (S6). As a result, the wired terminal (250) responds (S7).

  On the other hand, as a result of determining whether or not it is a multiple incoming call number, if it is a multiple incoming call number, first, the call is distributed to the wired subscribers (S8) (P1). Further, the virtual wired telephone number designated as the corresponding wired number is requested to pBSC (113) (S9). If the mobile gateway (112) requests a virtual wired telephone number from the pBSC (113), whether or not 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 only is stored.

  On the other hand, the pBSC (113) stores the direct information for the corresponding wireless terminal for which multiple incoming calls are set for the wired number, so that the mobile gateway (112) can receive multiple incoming calls to the pBSC (113). A virtual wired telephone number corresponding to the wireless terminal to be requested is requested.

  As a result, the pBSC (113) searches the 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). As a result, one of the wired terminal (250) and the wireless terminal (220) responds (S11). When the wired terminal does not respond, the wireless terminal can receive the incoming 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 result of the determination is that it is not a wired subscriber number, the mobile gateway 112 is a virtual subscriber allocated to the wireless terminal 220. A 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). As a result, the corresponding wireless terminal (220) responds (S13).

  FIG. 7 shows a procedure for a wireless terminal subscriber to make a call to an external subscriber, FIG. 8 shows a procedure for the wireless terminal subscriber to make a call to an internal subscriber, and FIG. 9 shows a procedure for the wireless terminal subscriber to make an external subscriber. Or a flow diagram for sending to an internal subscriber.

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

  The other party's number (for example, 031-ZZZ-ZZZZZ or 02-XXX-XXXX) is called by the wireless terminal (220) (for example, 016-AAA-BBBB) (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 (113) 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. (S23). At this time, the caller ID is changed by referring 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 it is an external calling number (S24), if it is not an external calling number, the internal subscriber (220, 240, 260) in the mobile zone (200) (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 charge.

  10 and 11 show a procedure for re-routing an incoming call when the mobile zone is absent.

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

  When any external subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the wired exchange (111) is called 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 it is determined that the number is not a multiple incoming call number, only the wired telephone terminal is called, and the call is distributed to the wired subscribers (S35). On the other hand, if it is determined that the number is a multiple incoming call number, the call is first distributed to the wired subscribers (S36). Next, the mobile gateway (112) requests a virtual number from the pBSC (113), is provided with a virtual number for the corresponding wired telephone number from the pBSC (113), and is matched 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 a wired telephone number via the virtual subscriber line allocated to the wireless terminal, the mobile gateway (112) transmits the corresponding wireless terminal (220 via the pBSC (113) and the pBTS (210). ).

  Next, if any one of the wired terminal (250) and wireless terminal (220) responds within the mobile zone (200), call processing is performed accordingly, and if not, the mobile zone (200) is subscribed. It is determined whether or not the person is absent (S38). If there is no response from the wired terminal (250) or wireless terminal (220) in the mobile zone (200) and it is determined that the mobile zone (200) is absent, the mobile gateway (112) Then, the wireless terminal (50a) in the public mobile communication network is called via the BTS (50) in the public mobile communication network via the PSTN (10) and the CDMA network (20) (S39). On the other hand, if the subscriber is in the mobile zone (200), but there is no response, “The subscriber cannot receive a call. Voice guidance messages can be sent (S40).

<Second embodiment>

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

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

  In the drawing, the description of the mobile zone (200) including the pBTS (210) 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 switch, the public telephone network (PSTN) (10) is connected to the central line interface (Trunk) of the mobile gateway (122) via NO.7 signaling. Connect.

The wired switch (121) is connected to the trunk line interface (Trunk) of the mobile gateway (122) via NO.7 signaling to provide a wired telephone service to subscribers outside the mobile zone (200). Installed.

  The wired switchboard (121) is a system that services a wired telephone network to subscribers outside the mobile zone (200), and the mobile gateway (122) is a call generated by a wired / wireless subscriber within the mobile zone (200). It is a system that processes.

  That is, the mobile gateway (122) performs call processing for the wired telephone network service and mobile communication service to the wired and wireless subscribers (220-270) in the mobile zone (200), and the wired switch (121) This system provides a wired telephone service to a wired subscriber (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 the pBTS (210) is provided in an apartment complex located within the mobile zone (200) where mobile communication services can be provided. a wired subscriber of residence, since pBTS (210) is not installed, can not provide a mobile communication service, the mobile zone (200) which can provide only general wired phone service located outside There may be a cable telephone service subscriber residing in the apartment complex.

In the case of such a large apartment complex, depending on the large number of subscribers, one mobile gateway (122) can be a subscriber in the mobile zone (200) and a subscriber outside the mobile zone (200). In some cases, it is not allowed to provide a wired telephone service due to the capacity of the exchange.

Therefore, in the case of a wired / wireless telephone subscriber in the mobile zone (200), the mobile gateway (122) provides the corresponding communication service, and a subscriber is located in a region outside the mobile zone (200). (121) to provide the corresponding communication service.

  As a result, 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 extension subscriber, and the determination result. If the incoming call is not an extension, for example, if it is a subscriber telephone number outside the mobile zone (200), it is transmitted to the wired switch (121) by a tandem call and the corresponding service is provided by the wired switch (121). Like that.

pBSC (123) is ligated to the mobile gateway (122) and pBTS (210), for general public mobile communications services are also coupled to BSC (40) of public mobile communication network.

  That is, when the mobile gateway (122) assigns a wired telephone number to any subscriber for the wired telephone service, the mobile gateway (122) connects the SLC interface to which the wired telephone number is assigned to the subscriber's wired telephone terminal (250) as a telephone line. Connect directly through. Accordingly, when the wired telephone terminal (250) hooks off the handset for a call, the wired telephone terminal (250) listens to the dial tone provided by the mobile gateway (122).

  Also, the mobile gateway 122 can assign a wired telephone number to each subscriber within a range acceptable by the SLC interface by providing a wired telephone service to its extension subscriber.

  Here, the wired telephone number is a commonly used wired telephone number connected to the wired telephone terminal (250) at the end thereof, and a virtual wired telephone number assigned only to the telephone number without being connected to the wired telephone terminal (250). There can be.

  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).

  For this purpose, 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 each telephone number is a virtual telephone number and information indicating whether it is registered in the multiple incoming service.

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

On the other hand, if 0 is set in the field indicating whether or not multiple incoming calls are allowed, this means 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 in a service that can perform multiple incoming calls.

  Accordingly, when an arbitrary wired telephone number registered with the multiple incoming service is called, the mobile gateway (122) has specific information on the virtual wired telephone number corresponding to the wireless terminal called simultaneously with the wired telephone number. If necessary, request the information from pBSC (123).

  If information on the virtual phone number of the wireless terminal connected to the corresponding wired phone number is received from pBSC (123), the virtual phone number is called to pBSC (123), and pBSC (123) stores the virtual phone number in the database (123b). The wireless terminal telephone number corresponding to the number is searched and the corresponding wireless terminal is called through pBST (210).

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

At this time, the caller ID of the wireless terminal transmitted to the mobile gateway (122) is a 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 mobile gateway 122 or an external subscriber that can be called through 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.

  pBSC (123) controls pBTS (210) to support public mobile and private mobile network services, call processing for subscribers, and analysis of other supplementary services and mobile gateway (122) Process various interfaces for linking with.

For this reason, when a private mobile communication service is to be provided, a subscriber of a wireless terminal adds identification information set in advance to the calling telephone number for service differentiation.

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

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

As an example, if the user enters the telephone number “# 212” via the wireless terminal, pBSC (123) will contain the identifier “#” that it wishes to use the private mobile communication service. It is determined that it is desired to use the communication service, and a call request signal including the telephone number “212” is transmitted to the mobile gateway 122 so that a call can be made with the extension subscriber having the extension number “212”. .

Also, if the user enters the phone number "# 02-212-8866", pBSC (123) will contain the identifier "#" that would like to use the private mobile communication service. And transmits a call request signal including the telephone number “02-212-8866” to the mobile gateway 122 and transmits the telephone number “02-212-8866 via the PSTN 10. "Make calls with public telephone network subscribers."

Also, if the user enters the phone number "# 016-212-8866", pBSC (123) will contain the identifier "#" that would like to use the private mobile communication service. The mobile phone (122) transmits a call request signal including the telephone number “016-212-8866” to the mobile gateway (122) and transmits the call request signal “016-212-8866” via the PSTN (10). To make calls with other public mobile communication service subscribers. An identifier other than "#" can be used .

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

  That is, the database (123c) stores information indicating whether or not 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 is stored.

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

  Therefore, even 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 call service via the pBTS (210), it can be roughly divided into two cases.

First, there may be a case where a call is requested using a private mobile communication service. In such a case, the caller ID transmitted from the pBTS (210) is sent to the caller ID by referring 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 sent to the caller ID transmitted from pBTS (210), so that the caller ID remains as it is. It is transmitted to BSC (40) of the communication network.

  The pBSC (123) manages the database (123c) for the multiple incoming service. That is, among the wired telephone terminals installed in the home, the wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming calls are set and the wireless terminal that is called at the same time when the corresponding wired telephone number is called It manages a database (123c) for virtual wired telephone numbers.

  As a result, when inquiring about a virtual wired telephone number that is set for multiple calls to a wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming calls have been set in the mobile gateway (122), the corresponding wired telephone number in the database (123c) A number (eg, 02-XXX-YYYY) can be searched 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 service. In the database (122b) built in the mobile gateway (122), whether or not an arbitrary wired telephone number has been received is stored, and information on the virtual wired telephone number assigned to each wireless terminal is stored. .

  On the other hand, in the database (123c) built in pBSC (123), information on the arbitrary wired telephone number for which multiple incoming calls are set and the virtual wired telephone number of the wireless terminal called by multiple incoming calls to that wired telephone number. Is saved.

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

  If there is a call from the PSTN (10) to the virtual wired phone, the mobile gateway (122) will respond to the virtual wired phone number via the pBSC (123) and pBTS (210) and wireless in the mobile zone (200). Call the terminal.

  If an incoming call response is received at the wireless terminal, the calling call is connected. If no incoming response is received, the service is terminated by the wired telephone service procedure.

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

  If any subscriber station (11) calls any wired phone number via the PSTN (10), the mobile gateway (122) is called the corresponding wired phone number via the PSTN (10) and the call is made. It is determined whether or not the received telephone number is an incoming call to the extension subscriber to the mobile gateway (122) (S101). If the result of the determination is that the extension is not an incoming call, a tandem call is transmitted to the wired exchange (121) (S102). On the other hand, when 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 it is a multiple incoming number via the database shown in FIG.

  First, it is determined whether or not it is a wired subscriber telephone number (S103). If it is not a wired subscriber number, it is a wireless subscriber number, and 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 corresponding wireless terminal (220) via the pBTS (210) (S104). As a result, the corresponding wireless terminal (220) responds (S105).

On the other hand, if the result is a wired subscriber number, it is determined whether the telephone number is set for wired / wireless multiple incoming (S106). If it is determined that it is a multiple incoming call number, if it is not a multiple incoming call number, the call is distributed to the wired subscribers (S107) . As a result, the wired terminal (230) responds (S108) . However, if it is a multiple incoming call number, first, the call is distributed to the wired subscribers (S109) . When the virtual telephone number of the wireless terminal connected to the corresponding telephone number is requested to pBSC (123) and the virtual telephone number is provided from pBSC (123), the virtual telephone number is called to 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 corresponding wireless terminal (220) via the pBTS (210) (S110) . As a result, one of the wired terminal (230) and the wireless terminal (220) responds (S111).

  FIG. 15 shows a procedure for a wireless terminal subscriber to make a call to an external subscriber, FIG. 16 shows a procedure for a wireless terminal subscriber to make a call to an internal subscriber, and FIG. 17 shows a procedure in which the wireless terminal subscriber makes a call to an external subscriber. Or it is a flowchart which transmits to an internal subscriber.

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

  The other party's number (for example, 031-ZZZ-ZZZZZ or 02-XXX-XXXX) is called by the wireless terminal (220) (for example, 016-AAA-BBBB) (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 (for example, 02-CCC-DDDD) assigned to the wireless terminal. (S123).

  The mobile gateway (122) determines whether or not the calling number sent from the wireless terminal is an external calling number (S124). If it is determined that the number is an external calling number, the external subscriber of the corresponding telephone number is called through the PSTN (10) (P9) (S125).

  On the other hand, when the mobile gateway (112) determines whether it is an external calling number (S124), if it is not an external calling number, the internal subscriber (220, 240, 260) in the mobile zone (200) (P10) (S126).

  At this time, the billing process can be billed via a billing device (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 charge.

  18 and 19 illustrate 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.

If any subscriber station (11) calls any wired phone number via the PSTN (10), the mobile gateway (122) is called the corresponding wired phone number via the PSTN (10) and the call is made. It is determined whether the received telephone number is an incoming call to the extension subscriber to the mobile gateway (121) (S131). If the result of the determination is that the extension is not an incoming call, a tandem call is transmitted to the wired exchange (S132).

  On the other hand, when 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 it is a multiple incoming number via a database owned by the mobile gateway (122).

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

Next, when at least one of the wired terminal (250) and the wireless terminal (220) responds within the mobile zone (200), the call processing is performed accordingly, and if not, the mobile zone (200) is entered. It is determined whether or not the subscriber is absent (S138). When it is determined that the mobile zone (200) is absent due to the absence of a response from the wired terminal (250) or wireless terminal (220) in the mobile zone (200), the mobile gateway (122) uses the PSTN (10) and 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) (S139). If you are in the mobile zone (200), but there is no response, you will receive a voice message such as "Please call me next because the subscriber is unable to receive calls" Can be sent (S140).

<Third embodiment>

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

  Referring to FIG. 20, the wired / wireless interlocking device (100) includes a group switch (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 mobile communication service to the wired and wireless subscribers (220-270) in the mobile zone (200), and wired subscription outside the mobile zone (200). This system provides a wired telephone service to a person (not shown).

For example, if it is installed in a small apartment complex, it resides in a ridge located in the mobile zone (200) where pBTS (210) is provided and wireless services can be provided by pBTS (210) Offers wired / wireless telephone link service to wired / wireless subscribers and subscribes to wired telephone service residing in a building located outside the mobile zone (200) where pBTS (210) cannot provide mobile communication services It is also to provide a general wired phone service to Shah, and the like.

pBSC (132), the population exchange (131) and pBTS (210) and is connected to, is also coupled to BSC (40) of public mobile communication network for public mobile communication service.

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

In the wired exchange (111), an extension subscriber card (SLC) interface is connected to each wired telephone terminal (230, 250, 270) via a telephone line.

  That is, when the collective exchange (131) assigns a wired telephone number to an arbitrary subscriber for the wired telephone service, the SLC interface to which the wired telephone number is assigned is called to the subscriber's wired telephone terminal (250). Connect directly through lines. Accordingly, when the wired telephone terminal (250) hooks off the handset for a call, the wired telephone terminal (250) listens to the dial tone provided by the collective exchange (131).

  In addition, the collective exchange (131) can assign a wired telephone number to each subscriber within a range acceptable by the SLC interface by providing a wired telephone service to its extension subscriber.

  Here, the wired telephone number includes a commonly used wired telephone number connected to the terminal by the wired telephone terminal (250) and a virtual wired telephone number assigned only to the telephone number without being connected to the wired telephone terminal (250). It is possible.

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

  For this purpose, the group switch (131) has a database (131b) for wired telephone numbers in the memory (131a). That is, as shown in FIG. 4, this database (131b) stores information indicating whether each telephone number is a virtual telephone number and information indicating whether it is registered in the multiple incoming service. .

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

On the other hand, if 0 is set in the field indicating whether multiple incoming calls are allowed, this means that the service is limited to existing services that call the wired telephone terminal corresponding to the corresponding wired telephone number, and if it is set to 1, This indicates that the service is registered in a service that can perform multiple incoming calls.

  Thus, when an arbitrary wired telephone number registered with the multiple incoming service is called, the group switch (131) has specific information on the virtual wired telephone number corresponding to the wireless terminal called simultaneously with the wired telephone number. If necessary, request the information from pBSC (132).

  When information on the virtual telephone number of the wireless terminal connected to the corresponding wired telephone number is received from pBSC (132), the virtual telephone number is called to pBSC (132). The pBSC (132) searches the database for a 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 an outgoing 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 to join the corresponding calling number. Call the person.

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

  At this time, the calling subscriber can be an internal subscriber of the collective exchange (131) or an external subscriber that can be called 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.

  pBSC (132) controls pBTS (210) to analyze subscriber call processing and other supplementary services to support public and private mobile network services and collective switches (131). Process various interfaces for linking with).

For this reason, in order to receive provision of a private mobile communication service , the subscriber of the wireless terminal adds identification information set in advance to the calling telephone number for distinguishing the service.

  Therefore, pBSC (113) uses this identification information to distinguish whether the 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 wireless terminal call transmitted from pBTS (210) is a call requesting a public mobile communication service, or if not, a call requesting a private mobile communication service. If the mobile communication service call is for public use, the BSC (40) of the public mobile communication network is clearly bypassed. If the call is for private mobile communication service, the private mobile communication service is provided. It is transmitted to the collective exchange (131).

As an example, if the user enters the telephone number “# 212” via the wireless terminal, pBSC (132) will contain the identifier “#” that it wishes to use the private mobile communication service. It is determined that it is desired to use the communication service, and 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”. .

Also, if the user enters the telephone number “# 02-212-8866”, pBSC (132) contains an identifier “#” that the private mobile communication service is desired to use. Is transmitted, a call request signal including the telephone number “02-212-8866” is transmitted to the collective exchange (131), and the telephone number “02-212-8866” is transmitted via the PSTN (10). "Make calls with public telephone network subscribers."

Also, if the user enters the telephone number “# 016-212-8866”, pBSC (132) contains the identifier “#” that the private mobile communication service is desired to use. The 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 make calls with other public mobile communication service subscribers.

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

  That is, the database stores information indicating whether or not 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 is stored.

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

  Accordingly, even when the virtual wired telephone number is called by the group switch (131), the corresponding wireless terminal can be called.

  On the other hand, when an arbitrary wireless terminal requests a call service via the pBTS (210), it can be roughly divided into two cases.

First, there may be 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), and the caller ID is set to the virtual wired telephone number by referring to the database shown in FIG. Convert and send to the group 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 sent to the caller ID transmitted from pBTS (210), so that the caller ID remains as it is. It is transmitted to BSC (40) of the communication network.

  The pBSC (132) manages the database (132c) for the multiple incoming service in the memory (132a). That is, among the wired telephone terminals installed in the house, the virtual telephone number assigned to the wireless terminal that is called at the same time when the wired telephone number (for example, 02-XXX-YYYY) set for multiple incoming calls and the corresponding wired telephone number is called It manages a database (132c) for wired telephone numbers.

  As a result, when inquiring about a virtual telephone number that has been set multiple times for a wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming calls have been set by the group switch (131), the corresponding wired telephone number (for example, , 02-XXX-YYYY), search for the virtual telephone number (02-CCC-DDDD) linked to the wired telephone number, and respond to the collective exchange (131).

  That is, a database (131b, 132c) is constructed in each of the group switch (131) and the pBSC (132) for the multiple incoming service. In the database constructed in the collective exchange (131), whether or not an arbitrary wired telephone number has been received is stored, and information on the virtual wired telephone number assigned to each wireless terminal is stored.

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

  In the wired / wireless interlocking device (100) configured in this way, not only a wired telephone service for a wired telephone terminal but also an incoming call to a designated wireless terminal is possible when a virtual wired telephone is called. In addition, when a wired telephone is called, the collective exchange (131) can make a simultaneous 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 via the pBSC (132) and pBTS (210), and the wireless in the mobile zone (200). Call the terminal.

  If an incoming call response is received at the wireless terminal, the calling call is connected. If no incoming response is received, the service is terminated by the wired telephone service procedure.

  FIG. 21 and FIG. 22 show a procedure in which a wired telephone and a wireless terminal are simultaneously received 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 station (11) calls an arbitrary wired telephone number via the PSTN (10), the collective exchange (131) is called the corresponding wired telephone number via the PSTN (10) and the telephone number Analyze. At this time, the group switch (131) determines whether the corresponding telephone number is a wired subscriber number (S201). If it is not a wired subscriber number, it is a wireless terminal subscriber, and the call is distributed to the corresponding wireless terminal via pBSC (132) and pBTS (210) (S202). As a result, the corresponding wireless terminal (220) responds (S203).

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

  However, the group switch (131) determines whether or not it is a multiple incoming call number, and if it is a multiple incoming call number, it first distributes the call to the wired subscriber (S207) (P14). Also, the virtual number is requested from pBSC (132), the virtual number retrieved from pBSC (132) is received, and the call is distributed to the corresponding wireless terminal (220) via pBSC (132) and pBTS (210). (S208) (P15). As a result, one of the wired terminal (250) and the wireless terminal (220) responds (S209). When the wired terminal is not responding, the wireless terminal can receive an incoming service anywhere in the mobile zone (200).

Meanwhile, when it is determined whether the multiple terminating number of the (S204), the result of the determination, if multi-call number, you distribute the call to the corresponding wireless terminal via the pBSC and (132) pBTS and (210). Thus the corresponding wireless terminal (220) that responds.

  FIG. 23 shows a procedure for a wireless terminal subscriber to make a call to an external subscriber, FIG. 24 shows a procedure for a wireless terminal subscriber to make a call to an internal subscriber, and FIG. 25 shows a procedure in which the wireless terminal subscriber makes a call to an external subscriber. Or it is a flowchart which transmits to an internal subscriber.

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

  The other party's number (for example, 031-ZZZ-ZZZZZ or 02-XXX-XXXX) is called by the wireless terminal (220) (for example, 016-AAA-BBBB) (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 caller ID is changed by referring 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 through the PSTN (10) (P16) (S215).

  On the other hand, when it is determined whether or not it is an external calling number in the group exchange (131) (S214), if the result is not an external calling number, the internal subscriber (220, 240, 260) in the mobile zone (200) (P17) (S216).

  At this time, the billing process can be billed via a billing device (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 charge.

  26 and 27 show a procedure for re-routing an incoming call when the mobile zone is absent.

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

  When an arbitrary subscriber station (11) calls an arbitrary wired telephone number via the PSTN (10), the collective exchange (131) is called upon receiving the corresponding wired telephone number via the PSTN (10). Analyzing the phone number. At this time, the group switch (131) determines whether the corresponding telephone number is a wired subscriber number (S221). If it is determined that the number is a wired subscriber number, the group switch 112 determines whether or not the corresponding telephone number is a multiple incoming number in the database shown in FIG. If it is determined that the number is not a multiple incoming call number, the call is distributed to the wired subscribers (S223). However, if it is determined that the number is a multiple incoming call number, the call is first distributed to the wired subscribers (P18) (S224). Next, the collective exchange (131) requests a virtual number from the pBSC (132) and is provided with a virtual number for the corresponding wired telephone number from the pBSC (132), 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 that 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 pBSC (132) and pBTS (210).

  Next, if at least one of the wired terminal (250) and the wireless terminal (220) responds within the mobile zone (200), the call processing is performed accordingly, and if not, the mobile zone (200) is subscribed. It is determined whether or not the person is absent (S226). If there is no response from the wired terminal (250) or the wireless terminal (220) in the mobile zone (200) and it is determined that the mobile zone (200) is absent, the collective exchange (131) uses the PSTN (10) and 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, you will receive a voice message such as "Please call me next because the subscriber is unable to receive calls" Can be sent (S228).
