Description

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

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

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

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

Of course, 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 as compared with mobile communication terminals using mobile communication services. There is a problem to be received.

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

  PLMN is a mobile switching center (MSC: Mobile Switching Center) (30) in charge of mobile communication services in any region, a base station controller (BSC) (40), and a base station (BTS: Base Station Transceiver Subsystem) (50) and HLR / VLR (Home Location Register / Visitor Location Register) (not shown). In the drawing, CDMA (20) generally shows a wireless environment in charge of a mobile communication service 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 a radio link control, a handoff function, etc., and the BTS (50) configures a radio communication path together with radio terminals belonging to its own communication service area, that is, its own cell area, and Perform the function of managing

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

  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 with a wired telephone terminal (80) using the public telephone network (PSTN) (10). There is no problem.

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

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

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

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

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, Despite the fact that the subscriber has another terminal, there is a disadvantage that the call cannot be connected with the subscriber.

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

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

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

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

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

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

In addition, by operating a virtual wired telephone number in the form of a general wired telephone service telephone number, an external subscriber can receive a telephone call with a wired telephone number via his / her own wireless terminal. At the time of calling, the caller ID is sent as a virtual wired telephone number, so that the subscriber side has the same effect as having a wired telephone terminal from the outside subscriber's point of view even when the wired telephone terminal is not actually installed. Can be provided. In addition, when an external subscriber or the like calls the wireless terminal of the subscriber, the telephone service can be received at a charging rate of the wired telephone service.

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

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

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

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

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

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

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

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

  In addition, xDSL subscriber line services that have been rapidly spreading recently can also be applicable.

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

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

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

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

  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 (for example, in the case of Korea, ) Can be realized by providing a mobile communication device.

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

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

At this time, a 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 intended 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). Accordingly, when the external subscriber calls the corresponding subscriber, the external subscriber can call the general wire telephone service subscriber, and the fee is settled according to the fee when calling the general wire telephone service subscriber. Therefore, such a telephone number is referred to as a virtual telephone number. The virtual telephone number is in the form of a general wired telephone number in the form of a general telephone number, which is simply a telephone number generated only by software in the wired / wireless interlocking device (100), and is arbitrary by a telephone line. It means a virtual telephone number other than a telephone number connected to a wired telephone terminal.

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

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

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

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

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

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

If the 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 is converted into a virtual telephone number (02-CCC-DDDD) and the converted caller ID is transmitted via the PSTN (10). As a result, the external subscriber receives the virtual telephone number for the corresponding call as caller ID information.

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

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

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

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

That is, if the wireless terminal (220, 240, 260) can receive the mobile communication service and is registered for use with the wired / wireless interlocking device (100), the wired / wireless interlocking device (100) transmits the pBTS (210). The mobile communication service is provided to the wireless terminals (220, 240, 260) via the mobile terminal.

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

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

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

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

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

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

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

First, a subscriber registration application for a wired / wireless service is received from an arbitrary extension subscriber. At the time of application for subscriber registration, the required information includes the subscriber's personal information, payment information, telephone number of a wired terminal, individual telephone number of a mobile communication terminal, virtual wired telephone number of a mobile communication terminal, and the like . Here, the personal information corresponds to a name, an address, a resident registration number, and the like.

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

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

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

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

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

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

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

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

  The mobile gateway (112) allocates the line of the wired telephone service extension subscriber of the wired switchboard (111) received via the central office interface to its own SLC interface, and 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 exchange (111) via the SLC interface of the mobile gateway (112) and the local line interface. Therefore, when hooking off the receiver for a call, the wired telephone terminal (250) hears the dial tone provided by the wired telephone exchange (111).

  In addition, the wired exchange (111) can provide a wired telephone service to its own extension subscriber, thereby assigning a wired telephone number to each subscriber within a range that the SLC interface can accept. The wired 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 is composed of a generally used wired telephone number with a wired telephone terminal (250) connected to its end, and a virtual wired telephone number to which only the telephone number is assigned without connecting the wired telephone terminal (250). It is possible.

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

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

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

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

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

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

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

  If the 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 searched for by pBSC (113). And via 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) I do.

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

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

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

The pBSC (113) controls the pBTS (210) to analyze the call processing of subscribers and other supplementary services to support the public mobile network and private mobile network services, and the mobile gateway (112). Handles various interfaces for interlocking.

For this reason, when receiving the provision of the private mobile communication service , the subscriber of the wireless terminal adds predetermined identification information to the calling telephone number to distinguish the service.

  Therefore, the pBSC (113) uses this identification information to distinguish whether the outgoing call is a call for a public mobile communication service or otherwise a call for 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 for requesting a mobile communication service for public use, or otherwise, a call for requesting a mobile communication service for private use. If the call is a public mobile communication service call, the call is clearly bypassed to the BSC (40) of the public mobile communication network, and if the call is a private mobile communication service call, the mobile communication service is provided so that the private mobile communication service is provided. The information is transmitted to the gateway (112).

As an example, if the user inputs a telephone number "# 212" through the wireless terminal, the pBSC (113) includes the identifier "#" that desires to use the private mobile communication service. If it is determined that the user wants to use the communication service, 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 inputs the telephone number "# 02-212-8866", the pBSC (113) includes the identifier "#" for using the private mobile communication service. It is determined that it is desired to use the telephone, and a call request signal including the telephone number "02-212-8866" is transmitted to the mobile gateway (112) to make a telephone call via the public telephone network via the wired exchange (111). Make calls with the public telephone network subscriber with the number "02-212-8866" possible.

Also, if the user inputs the telephone number "# 016-212-8866", the pBSC (113) includes the identifier "#" that desires to use the private mobile communication service. The mobile telephone (112) transmits a call request signal including the telephone number "016-212-8866" to the mobile gateway (112), and transmits the call request signal via the public telephone network via the wired exchange (111). A call can be made with a public mobile communication service subscriber at "016-212-8866" via a mobile communication network.

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

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

For example, if 0 is set in the field indicating whether a virtual wired number exists, it means that 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 the corresponding virtual wired telephone number is stored.

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

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

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

On the other hand, in case of not using the private mobile communication service, by pBTS (210) granted MIN number to the public mobile communication network caller ID transmitted from is sent, the public mobile the caller ID intact It is transmitted to the BSC (40) of the communication network.

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

  Thus, when the mobile gateway (112) inquires of a wired telephone number (e.g., 02-XXX-YYYY) for which multiple incoming calls have been set, the corresponding wired telephone number is searched in the database (113c). 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 (112).

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

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

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

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

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

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

  When an arbitrary subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the wired exchange (111) is called 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 based on its own database (112b) shown in FIG. 4 (S5). If the result of the determination is that it is not a multiple incoming number, the call is distributed to wired subscribers (S6). Then, the wired terminal (250) responds (S7).

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

  On the other hand, pBSC (113) stores direct information for the corresponding wireless terminal for which multiple incoming call is set for the wired number, so that multiple incoming calls from mobile gateway (112) to pBSC (113) are stored. Requesting a virtual wired telephone number corresponding to the wireless terminal to be used.

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

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

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

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

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

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

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

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

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

  FIG. 10 and FIG. 11 show a procedure in which an incoming call is re-routed when not in the mobile zone.

  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 any wired telephone number via the PSTN (10), the wired exchange (111) is called for the corresponding wired telephone number via the PSTN (10), and the 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 from the database (112b) (S34). If the result of the determination is that it is not a multiple incoming number, it means that only the wired telephone terminal is being called, so the call is distributed to wired subscribers (S35). On the other hand, if the result of the determination is that the number is a multiple incoming number, the call is first distributed to the wired subscribers (S36). Next, the mobile gateway (112) requests the virtual number from the pBSC (113), and the virtual number for the corresponding wired telephone number is provided from the pBSC (113), and the corresponding virtual number is provided via the pBSC (113) and the pBTS (210). The call is distributed to the wireless terminal (220) (S37). On the other hand, when the mobile gateway (112) receives the wired telephone number via the virtual subscriber line allocated to the wireless terminal, the mobile gateway (112) receives the corresponding wireless terminal (220) via the pBSC (113) and the pBTS (210). ).

  Next, if at least one of the wired terminal (250) and the wireless terminal (220) answers in the mobile zone (200), the call processing is performed accordingly, and if not, the mobile zone (200) is joined. It is determined whether or not the person is absent (S38). 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 not present, the mobile gateway (112) communicates with the wired exchange (111). 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 is unable to receive a call, please call next" (S40).

<Second embodiment>

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

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

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

In the embodiment, as an example in which the mobile gateway (122) is used as a tandem switch, the public telephone network (PSTN) (10) is connected to the local line interface (Trunk) of the mobile gateway (122) via NO.7 signaling. To connect.

The wired exchange (121) is connected to the central office interface (Trunk) of the mobile gateway (122) via No. 7 signaling to provide a wired telephone service to subscribers outside the mobile zone (200). Will be installed.

  The wired switchboard (121) is a system for providing a wired telephone network to subscribers outside the mobile zone (200), and the mobile gateway (122) is a system for providing calls to wired / wireless subscribers within the mobile zone (200). Is a system for processing.

  That is, the mobile gateway (122) performs call processing for the wired telephone network service and the mobile communication service to the wired / wireless subscribers (220-270) in the mobile zone (200), and the wired exchange (121) This is a system for providing a wired telephone service to wired subscribers (not shown) outside the zone (200).

For example, when a telephone office is set up for a large apartment complex, a pBTS (210) is provided, and the pBTS (210) provides a mobile communication service to the apartment complex located in the mobile zone (200). 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 wired telephone service subscribers residing in apartment complexes.

In the case of a large-scale apartment complex as described above, one mobile gateway (122) and a subscriber in an area outside the mobile zone (200) may be used by one mobile gateway (122) depending on the number of subscribers. In some cases, it is not possible to provide a wired telephone service to the exchange because of the capacity of the exchange.

Therefore, in the case of a wired / wireless telephone subscriber in the mobile zone (200), the corresponding communication service is provided by the mobile gateway (122), and a subscriber outside the mobile zone (200) is provided with a separate wired exchange. The communication service is to be provided via (121).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

As an example, if the user inputs a telephone number "# 212" via a wireless terminal, pBSC (123) contains an identifier "#" that desires to use a private mobile communication service, If it is determined that it is desired to use the communication service, 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 inputs the telephone number "# 02-212-8866", the private mobile communication service is included in the pBSC (123) because the identifier "#" that includes the use of the private mobile communication service is included. The mobile terminal (122) 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). "Enable calls to public telephone network subscribers.

Also, if the user inputs a telephone number "# 016-212-8866", pBSC (123) contains an identifier "#" that desires to use the private mobile communication service. The mobile terminal (122) transmits a call request signal including the telephone number "016-212-8866" to the mobile gateway (122), and transmits "016-212-8866" via the PSTN (10). Call to public mobile communication service subscribers. Other identifiers besides "#" can be used .

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

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

For example, if 0 is set in the field indicating whether a virtual wired number exists, it means that 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 the corresponding virtual wired telephone number 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 calling service via the pBTS 210, it can be roughly classified into two cases.

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

On the other hand, in case of not using the private mobile communication service, by pBTS (210) granted MIN number to the public mobile communication network caller ID transmitted from is sent, the public mobile the caller ID intact It is transmitted to the BSC (40) of the communication network.

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

  This allows the mobile gateway (122) to inquire of a wired telephone number (for example, 02-XXX-YYYY) to which a multiplex incoming call has been set, when inquiring about the multiplexed virtual wired telephone number. It can retrieve the number (eg, 02-XXX-YYYY), find the virtual telephone number (02-CCC-DDDD) linked to the wired telephone number, and respond to the mobile gateway (122).

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

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

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

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

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

  FIG. 13 and FIG. 14 show a procedure in which a call is received by a wired telephone and a wireless terminal at the same time when a wired telephone is called.

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

  When an arbitrary subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the mobile gateway (122) is called for the corresponding wired telephone number via the PSTN (10), and the 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 it is determined that the call is not an extension call, the call is transmitted to the wired exchange (121) by a tandem call (S102). On the other hand, if the call is an extension incoming call, the mobile gateway (122) analyzes the telephone number transmitted from the PSTN (10). At this time, the mobile gateway (122) can know via the database shown in FIG. 4 whether or not the corresponding telephone number is a wired telephone number and whether or not the corresponding telephone number is a multiple incoming number.

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

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

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

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

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

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

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

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

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

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

  FIG. 18 and FIG. 19 show a procedure in which an incoming call is re-routed when not in the mobile zone.

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

When an arbitrary subscriber terminal (11) calls an arbitrary wired telephone number via the PSTN (10), the mobile gateway (122) is called for the corresponding wired telephone 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 an extension subscriber to the mobile gateway (121) (S131). If the result of the determination is that the call is not an extension call, the call is transmitted to the wired exchange by a tandem call (S132).

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

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

Next, if at least one of the wired terminal (250) and the wireless terminal (220) responds in the mobile zone (200), the call is processed accordingly, and if not, the mobile zone (200) It is determined whether or not the subscriber is absent (S138). 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 mobile gateway (122) uses the PSTN (10) and CDMA network. A wireless terminal (50a) in the public mobile communication network is called via the BTS (50) in the public mobile communication network via (20) (S139). If you are in the mobile zone (200) but there is no response, a voice guidance message such as "The subscriber is unable to receive a call, please call next" Can be transmitted (S140).

<Third embodiment>

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

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

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

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

For example, when installed in a small apartment complex, a pBTS (210) is provided and lives in a ridge located in a mobile zone (200) where wireless services can be provided by the pBTS (210). Provide wired / wireless telephone interlocking services to wired / wireless subscribers, etc., and subscribe to wired telephone service resident in a building located outside the mobile zone (200) where mobile communication services cannot be provided by pBTS (210) also provides 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 embodied in one collective switch (131), the public telephone network (PSTN) (10) is connected to the central office interface (Trunk) of the collective switch (131). Ligation via NO.7 signaling.

The wired exchange (111) has an extension subscriber card (SLC: Subscriber Line Card) interface connected to each of the wired telephone terminals (230, 250, 270) via a telephone line.

  That is, when assigning a wired telephone number to an arbitrary subscriber for wired telephone service, the collective exchange (131) calls the SLC interface assigned with the wired telephone number to the subscriber's wired telephone terminal (250). Connect directly via wire. Therefore, when hooking off the receiver for a call, the wired telephone terminal (250) hears the dial tone provided by the collective exchange (131).

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

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

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

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

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

On the other hand, if 0 is set in the field indicating whether or not multiple incoming calls are possible, it indicates that the service is limited to the existing service for calling the wired telephone terminal corresponding to the corresponding wired telephone number, and if it is set to 1, Indicates that the service is registered as a service capable of performing multiple incoming calls.

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

  When 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 the wireless terminal telephone number corresponding to the virtual telephone number, and calls the wireless terminal via the pBST (210).

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

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

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

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

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

For this reason, when receiving the provision of the private mobile communication service , the subscriber of the wireless terminal adds predetermined identification information to the calling telephone number to distinguish the service.

  Therefore, the 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 call of the wireless terminal transmitted from the pBTS (210) is a call for requesting a public mobile communication service, or otherwise, a call for requesting a private mobile communication service. However, if the call is a public mobile communication service call, the call is clearly bypassed to the BSC (40) of the public mobile communication network, and if the call is a private mobile communication service call, the private mobile communication service is provided. The information is transmitted to the collective exchange (131).

As an example, if the user inputs a telephone number "# 212" through the wireless terminal, the pBSC (132) includes the identifier "#" that desires to use the private mobile communication service. If it is determined that the user wants to use the communication service, 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 inputs the telephone number "# 02-212-8866", the pBSC (132) includes the identifier "#" that desires to use the private mobile communication service. It is determined that it is desired to use the telephone number, and a call request signal including the telephone number “02-212-8866” is transmitted to the collective exchange (131), and the telephone number “02-212-8866” is transmitted via the PSTN (10). "Enable calls to public telephone network subscribers.

If the user inputs the telephone number "# 016-212-8866", the pBSC (132) includes the identifier "#" for using the private mobile communication service. It is determined that it is desired to use the telephone number, and a call request signal including the telephone number “016-212-8866” is transmitted to the collective exchange (131), and “016-212-8866” is transmitted via the PSTN (10). Call to public mobile communication service subscribers.

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

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

For example, if 0 is set in the field indicating whether a virtual wired number exists or not, it means that 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 the corresponding virtual wired telephone number is stored.

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

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

First, there is a case where a call is requested using a private mobile communication service. In such a case, the MIN number assigned to the public mobile communication network is transmitted to the caller ID transmitted from the pBTS (210), and the database shown in FIG. 5 is referred to, and the caller ID is converted to the virtual wired telephone number. Convert it and send it to the collective exchange (131).

On the other hand, in case of not using the private mobile communication service, by pBTS (210) granted MIN number to the public mobile communication network caller ID transmitted from is sent, the public mobile the caller ID intact It is transmitted to the BSC (40) of the communication network.

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

  With this, for a wired telephone number (for example, 02-XXX-YYYY) for which multiple incoming calls are set in the collective exchange (131), when inquiring about a virtual wired telephone number for which multiple settings are made, the corresponding wired telephone number (for example, , 02-XXX-YYYY) and a virtual telephone number (02-CCC-DDDD) linked to the wired telephone number, and can respond to the collective exchange (131).

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

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

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

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

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

  FIG. 21 and FIG. 22 show a procedure for simultaneously receiving an incoming call to the wired telephone and the wireless terminal when calling the wired telephone.

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

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

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

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

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

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

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

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

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

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

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

  FIG. 26 and FIG. 27 show a procedure in which an incoming call is re-routed when not in the mobile zone.

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

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

  Next, if at least one of the wired terminal (250) and the wireless terminal (220) answers in the mobile zone (200), the call is processed accordingly, and if not, the mobile zone (200) is joined. 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. A wireless terminal (50a) in the public mobile communication network is called via the BTS (50) in the public mobile communication network via (20) (S227). If you are in the mobile zone (200) but there is no response, a voice guidance message such as "The subscriber is unable to receive a call, please call next" Can be transmitted (S228).
