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

In general, conventional public telecommunication networks can be classified into wireline telephone service and mobile telecommunication telephone service.

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

As such, in the case of a wired telephone service, there is no mobility since the telephone line 70 is connected to the wired telephone terminal 80 through a telephone line.

Of course, a wireless telephone for performing wireless communication using the wired telephone terminal body and the 900 MHz wireless band has been developed and used, but there is a problem in that mobility is much limited compared to a mobile communication terminal using a mobile communication service.

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

The PLMN is a mobile switching center (MSC) 30, a base station controller (BSC) 40, a base station transceiver subsystem (BTS) (BTS), which is responsible for mobile communication services in an arbitrary area. 50), and Home Location Register / Visitor Location Register (HLR / VLR) (not shown). In the figure, CDMA 20 collectively represents a wireless environment in charge of mobile communication services in another region.

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

The BSC 40 performs radio link control and handoff functions, and the BTS 50 configures a radio communication path and manages radio resources together with a radio terminal belonging to its communication service area, that is, its cell area. Perform the functions.

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 stores information of an MS existing in a cell area of a corresponding MSC among a plurality of MSCs. Temporarily stored database. If the MS moves to a cell area managed by another MSC, the information stored in the VLR is deleted.

As described above, even in the case of the mobile communication telephone service using the PLMN, there is a problem in that each service is independent and does not have any correlation since it is not interworked with the wired telephone terminal 80 using the public telephone network (PSTN) 10.

On the other hand, in general, the mobile communication service is available anywhere, regardless of the limited area, such as the premises, but this is using a mobile communication service system, it was not designed to communicate wirelessly without additional charge within the set area.

That is, in order to make a call between a landline telephone service terminal using a wireline telephone service and a mobile communication terminal of a mobile communication service subscriber, each call is connected to a public network and then a call is connected to a counterpart terminal.

Here, the public network includes a PLMN and a PSTN. Accordingly, even if the wired subscriber and the mobile communication service subscriber make a call in the same building or the same apartment complex, there was an inconvenience of being charged.

In addition, when a subscriber is simultaneously provided with a wireline telephone service and a mobile communication service, there is a problem in that a heavy burden of using the communication service is required because the subscribers have to pay for each communication fee.

In addition, when one subscriber is simultaneously provided with a wired telephone service and a mobile communication service, and the other person knows only one of the telephone numbers and calls the corresponding terminal, if the terminal fails to answer, the subscriber has another terminal. Despite that, there was an inconvenience in not being able to make a call with the subscriber.

Of course, if there is a call to any terminal using the call forwarding service, it can be called to another designated terminal, but this is only limited to the case that is set in advance, if the incoming call service is set of two terminals There was a problem in that only the call forwarding designated terminal was called.

 Accordingly, an object of the present invention is to provide a method for operating a wired / wireless telephone interworking service for providing mobility to a conventional fixed line telephone service subscriber.

In addition, another object of the present invention is to provide a method for operating a wired / wireless telephone interworking service that can reduce the burden due to duplication of billing when a subscriber simultaneously uses a wired telephone service and a mobile communication service.

In addition, 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, a call can be answered at all terminals possessed by the subscriber when the other person calls one of them. The purpose is to provide a method for operating a wired / wireless telephone interworking service.

According to an aspect of the present invention for achieving this purpose, receiving a subscriber registration request for wired and wireless services from any extension subscriber, and at least one wired terminal and public / private mobile communication terminals according to the subscriber registration application; And a wired and wireless service registration for each extension subscriber by assigning a wired telephone number to the subscriber, and when an arbitrary wired telephone number is called, calling a wired terminal corresponding to the wired telephone number and interworking with the wired telephone number. If there is a public / private mobile communication terminal to be connected, the wired / wireless telephone interworking service including calling the corresponding public / private mobile communication terminal through a mobile communication network and performing charging according to the use of the wired / wireless service for each subscriber. Provide operational methods.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, a mobile phone using a mobile communication network will use the term wireless phone for convenience as a concept corresponding to a wired telephone service terminal using a wired telephone service. Therefore, the term "wireless terminal" is limited to the mobile communication terminal.

2 is a network diagram illustrating a concept of a wired / wireless telephone interworking service system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the wired / wireless telephone interworking 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 provides a wired telephone service and a public service to a registered subscriber. / Private base station apparatus (private BTS), which is connected to the wired / wireless interworking device 100 for providing a private mobile communication service and a wireless environment for a private mobile communication service in its communication area, is connected to the wired / wireless interworking device 100. pBTS 210), wireless terminals 220, 240, and 260 that receive public / private mobile communication services through pBTS 210, and wired telephone service terminals 230, 250, and 270 that receive wired telephone service. )

The wired / wireless interworking device 100 provides a wired telephone service to the wired telephone service terminals 230, 250, and 270 connected through a telephone line, and provides a wireless terminal 220, 240, or 260 registered to use a private mobile communication service. It provides a public / private mobile communication service through the pBTS (210). Of course, the public mobile communication service is also provided to a general wireless terminal (not shown) that is not registered in the private mobile communication service. In addition, it performs a wired and wireless interworking service interworking a wired telephone service and a mobile communication service.

The wired / wireless interworking apparatus 100 includes a function of a wireline telephone station that performs a wireline telephone service. That is, a telephone (e.g., 02-XXX-YYYY) is provided to a subscriber registered in the landline telephone service by providing an exchange device (not shown) for landline telephone service, and the landline telephone installed in the subscriber's home. The wired telephone service is provided through a telephone line connected to the service terminals 230, 250, and 270.

For example, the fixed line telephone service corresponds to a general fixed line telephone service provided to a subscriber through a telephone company in Korea Telecom, and may include various additional services such as an Internet service including basic outgoing and incoming service.

In addition, xDSL subscriber line services that are rapidly spreading recently may also be applicable.

Accordingly, the wire / wireless interworking device 100 may be implemented in conjunction with an exchange installed in a conventional telephone station, may be implemented by improving the exchange installed in the telephone station, private switching network having a private exchange Can also be implemented.

The landline telephone service terminal capable of receiving wired telephone service from the wired / wireless interworking device 100 may also include general landline telephones 230 and 250, and a personal computer 270 and various equipment for a home network (not shown). ) May be applicable. The general wired telephones 230 and 250 may also include a mobile terminal using 800 MHz wireless and a main body connected via a telephone line.

Meanwhile, the wired / wireless interworking apparatus 100 operates a private mobile communication network in the limited communication area 200.

Herein, a private mobile communication network is generally used to distinguish a public mobile communication network operated nationwide by various mobile communication providers (for example, 01X service provider in Korea). It means a mobile communication service for providing a quality service to its subscribers in a limited area that can be afforded by the base station.

Therefore, such a service may be operated in connection with any exchange provider and mobile communication device provider, or installed and implemented by a mobile communication device installed by an operator having an existing wired telephone network (for example, Korea Telecom). Can also be.

To this end, the wire / wireless interworking device 100 is provided with a device (not shown) for a mobile communication service to a subscriber registered with a mobile communication telephone service (Mobile Identifier Number: MIN) (for example, 02-CCC). -DDDD) and provides a mobile communication telephone service through the pBTS 210 to the wireless terminals 230, 250, and 270 located in their private communication areas.

Of course, since the wireless terminals 230, 250, and 270 registered in the mobile communication service of the wired / wireless interworking device 100 are registered in the service of the public mobile communication network and receive a mobile communication service using a general public mobile communication network, the corresponding mobile communication A separate mobile communication terminal telephone number (MIN) (for example, 016-AAA-BBBB) is received from a service provider.

At this time, the individual telephone number assigned to the wireless terminal registered in the mobile communication service in the wire / wireless interworking apparatus 100 uses a wired telephone number format (for example, 02-CCC-DDDD). The use of the landline telephone number format is for an external subscriber using the landline telephone service to be considered as a general landline telephone service subscriber when making a call to the subscriber via the PSTN 10. Accordingly, the external subscriber may make a call as a general landline telephone service subscriber when calling the subscriber, and the fee is also settled at the rate when the subscriber is called. Therefore, this telephone number is called a virtual telephone number. The virtual telephone number is a form of a general telephone number in the form of a telephone number, which is a telephone number generated only by software in the wired / wireless interworking device 100, and a telephone number to which an arbitrary wired telephone terminal is connected by a telephone line. This means that it is not a virtual phone number.

Accordingly, the wired / wireless interworking apparatus 100 may have three types of subscribers.

First, subscribers who use only landline services. In this case, the subscriber receives a random wired telephone number from the wired / wireless interworking device 100 and connects a wired terminal to a telephone line installed up to the home to use a wired telephone service.

Next is the subscriber using only mobile communication services. In this case, the subscriber is also registered in the public mobile communication network. Therefore, this subscriber is given two telephone numbers. One is a phone number given from a public mobile communication network, and the other is a phone number given from a wired / wireless interworking device 100. The wired / wireless interworking device 100 stores the information on the telephone number granted by the subscriber and the telephone number granted from the public mobile communication network provider as a database.

Finally, subscribers use both landline and mobile communication services. In this case, the subscriber is a subscriber who receives an arbitrary wired telephone number from the wired / wireless interworking device 100 and connects a wired terminal to a telephone line installed up to the home to use a wired telephone service and also uses a mobile communication service using a wireless terminal. . Thus, this subscriber is given three telephone numbers. One is a wired telephone number assigned 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 virtual telephone number given to a wireless terminal in a wired / wireless interworking device 100. Accordingly, the wired / wireless interworking apparatus 100 stores the above three types of telephone number information for the corresponding subscriber as a database.

Wired and wireless interworking device 100 may provide a differentiated service for each subscriber.

Subscribers using only regular landline telephone services are provided with outgoing and incoming servers by general landline telephone services over telephone lines.

If the subscriber using only the mobile communication service has a call request through the wireless terminal, the caller ID is transmitted from the wireless terminal to the MIN (016-AAA-BBBB) given from the public mobile communication only. Converted to (02-CCC-DDDD) and transmits the converted caller ID through the PSTN (10). Accordingly, the external subscriber receives the virtual telephone number as the caller ID information for the call.

It is possible to provide a multi-landing function to a subscriber using both a wired telephone service and a mobile communication service. Multi-incoming function means that a ring signal is simultaneously transmitted to a wireline telephone service terminal and a wireless terminal.

That is, when the telephone number of the landline telephone service terminal (02-XXX-YYYY) is called from the outside, the ring signal is transmitted to the landline telephone terminal corresponding to the landline telephone number through the telephone line and the corresponding landline telephone number is transferred. Branch to retrieve the virtual phone number registered to the subscriber to call the corresponding wireless terminal through the pBST (210). In addition, when there is no response from the wireless terminal even though the wireless terminal is called through the pBST 210, it is determined that the wireless terminal is not in the private communication service area and the BTS 50 of the public mobile communication network is passed through the public mobile communication network. Call the wireless terminal through.

In this case, the wired / wireless interworking apparatus 100 should have a database for each telephone number. For example, if there are multiple call destinations for a certain phone number, and if multiple call destinations are set, it must have a database of virtual phone numbers for each wired telephone number and virtual phone numbers for each telephone number of a public mobile communication network.

And, if there is a call connection request for an extension or an external subscriber from any extension subscriber or calls an extension subscriber from any external subscriber, the corresponding call connection service can be performed using this database.

That is, if the wireless terminal (220, 240, 260) is registered in the wired and wireless interlocking device 100 to receive a mobile communication service, the wired and wireless interlocking device 100 is a wireless terminal 220 through the pBTS (210) To provide a mobile communication service.

In addition, the wire / wireless interworking device 100 also performs a wired communication service with the PSTN 10. For example, the wired / wireless interworking device 100 is connected to a public mobile communication network via a PSTN 10 when a wireless terminal registered with a service wants to communicate with a wireless terminal (not shown) whose service is not registered. Set up a communication channel with a phone to make a call.

The wired / wireless interworking apparatus 100 sets a communication path with a public network subscriber through the PSTN 10 when the wireless terminals 220, 240, and 260 registered with the service want to talk to the public network subscriber 11 instead of the extension subscriber. Make the call available.

On the other hand, the pBTS 210 is a wireless terminal 220, 240, 260 registered in the communication area (hereinafter referred to as a mobile zone) 200 using the private mobile communication service to the wired / wireless interworking device 100. When requesting the setting of the wireless communication path, a public / private mobile communication service is provided by constructing a wireless communication path and managing radio resources.

In addition, the wireless mobile station which is not registered in the private mobile communication service is provided through the public mobile communication network.

In addition, the wireless terminal (220, 240, 260) or wired telephone service terminal (230, 250) or other wireless terminal (220, 240, 260) registered to use the private mobile communication service through the wired or wireless interlocking device (100) And 270) and call services.

That is, the pBTS 210 sets the wireless communication path when the wireless terminals 220, 240, and 260, which are registered to use the mobile communication service, request the wireless communication path to the wired / wireless interworking device 100. If the wireless terminal (not shown) that is not registered in the wired / wireless interworking device 100 to use the private mobile communication service requests the wireless communication path setting, the public mobile communication network is established through the BSC 40. Use it.

For the service operation of the wired / wireless interworking service system configured as described above, the following procedure is required.

First, a subscriber registration application for wired or wireless service is received from any extension subscriber. Information required for the subscriber registration application may include personal information, payment information, a telephone number of a wired terminal, an individual telephone number of a mobile communication terminal, a virtual wired telephone number of a mobile communication terminal, and the like. The personal information may include a name, address, social security number, and the like.

According to the subscriber registration application, wired and wireless service registration is performed for each extension subscriber by assigning a wired telephone number to one or more wired terminals and public / private mobile communication terminals.

When registering a wired or wireless service, a wired telephone number assigned to a wired terminal constituting an extension network, a wired telephone number given to a public / private mobile communication terminal, and an individual telephone assigned to a public / private mobile communication terminal by a public mobile communication network The procedure of registering the number (MIN) in the database as the extension subscriber information is performed.

Then, for any landline telephone number, first identification information indicating whether the landline telephone number is a landline telephone number to which the terminal is connected or a landline telephone number to which the terminal is not connected, and whether the landline telephone number uses a multiple incoming service. And registering the wired telephone number of the public / private mobile communication terminal, which is called by the second identification information and the multi-calling function, indicated in the database. After completing the registration process, if any landline telephone number is called, the mobile terminal is called if there is a public / private mobile communication terminal to be called at the same time by calling the wireline terminal corresponding to the wireline telephone number and linked to the wireline telephone number. Call the public / private mobile communication terminal through. Each station subscriber can perform a procedure for performing billing for the use of wired / wireless services. In case of using a private mobile communication network, the billing rate may be applied. In the case of using a public mobile communication network, the billing rate may be applied.

3 is a system configuration diagram illustrating a concept of a wired / wireless telephone interworking service system according to an embodiment of the wired / wireless interworking device shown in FIG. 2.

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

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

In one embodiment, the mobile gateway 112 is used as an exchange interworking with the wired switch 111. For example, the public switched telephone network (PSTN) 10 signals N0.7 to the trunk line interface Trunk of the wired switch 111. Is connected through.

The wired switch 111 has a subscriber line card (SLC) interface connected to the trunk line interface (Trunk) of the mobile gateway 112 through E1 signaling. Where E1 is the European standard for 2.048Mbps digital lines with 32 timeslots. Another example is T1, a European standard for 24-channel 1.544Mbps digital lines, and T3 (DS3) is digital signal level 3 operating at 44.736Mbps.

That is, when the wired telephone exchange 111 allocates a wired telephone number to any subscriber for wired telephone service, the wired switch 111 directly connects the SLC interface to which the wired telephone number is assigned to the wired telephone terminal 250 of the subscriber through a telephone line. Rather, the SLC interface is connected to the trunk line interface of the mobile gateway 112 and passed to the mobile gateway 112.

The mobile gateway 112 allocates a line of a wired telephone service extension subscriber of the wired telephone exchange 111 received through the trunk line interface to its SLC interface and connects it to the wired telephone terminal 250 through the telephone line.

Accordingly, the wired telephone terminal 250 is connected to the SLC interface of the wired switch 111 via the SLC interface and the trunk line interface of the mobile gateway 112. Therefore, the wired telephone terminal 250 hears a dial tone provided by the wired telephone exchange 111 when the handset is hooked off for the call.

In addition, the wired switch 111 may assign a wireline telephone number to each subscriber within the range that the SLC interface can accommodate, as the wireline switch 111 provides the wireline telephone service to its extension subscriber. The wired switch 111 may have a database including a wired telephone number assigned to extension subscribers. This database is implemented in memory.

Here, the wired telephone number may be a wireline telephone number generally used to which the wireline telephone terminal 250 is connected at its end, and the virtual wireline telephone number to which the wireline telephone terminal 250 is not connected and merely a phone number is assigned. There may be.

However, the wired switch 111 side does not separate the normal wired telephone number and the virtual wired telephone number separately. This is because the wired switch 111 assigns a telephone number for an extension subscriber to the SLC interface and hands over to the trunk line interface of the mobile gateway 112 through the SLC interface. Connecting and not connecting the wired telephone terminal 250 to the end is a matter to be involved in the mobile gateway 112 and the wired switch 111 may be managed only with the extension subscriber information.

On the other hand, the mobile gateway 112 is connected to the pBSC 113 through the E1 signaling, and performs the function of interworking the wireline 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 connects to and assigns to the pBSC 113 through E1 signaling is related to the wireless terminal.

The mobile gateway 112 has a database 112b for the wired telephone number given from the wired switch 111. This database 112b may be implemented in memory 112a. That is, as shown in Fig. 4, this database stores information indicating whether or not it is a virtual telephone number for each telephone number, and information indicating whether or not it is registered in a multi-telephone service.

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

On the other hand, if it is set to 0 in the field indicating whether multiple calls are received, it indicates that the service is limited to an existing service calling a landline telephone terminal corresponding to the corresponding landline telephone number. It indicates that you are registered with the service.

Accordingly, the mobile gateway 112 needs specific information about the virtual wired telephone number corresponding to the wireless terminal to be called simultaneously with the wired telephone number when any wired telephone number registered with the multi-incoming service is called. Accordingly, the pBSC 113 requests the information.

When receiving the information on the virtual telephone number of the wireless terminal connected to the wired telephone number from the pBSC 113, finds the virtual telephone number in its database to find the wireless terminal corresponding to the virtual telephone number pBSC 113 and pBST Called via 210.

On the other hand, when the mobile gateway 112 receives the originating service request from any wireless terminal from the pBSC 113, the mobile gateway 112 transmits the caller ID and the caller ID of the wireless terminal received from the wireless terminal to the wired switch 111.

At this time, the caller ID of the wireless terminal delivered to the wired switch 111 becomes a virtual wired telephone number (for example, 02-CCC-DDDD) assigned to the wireless terminal. Accordingly, the wired switch 111 loads the caller ID to call the subscriber of the corresponding calling number.

At this time, the subscriber of the originating call may be an internal subscriber of the wired switch 111 or an external subscriber which may be called through the PSTN 10.

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

The pBSC 56 controls the pBTS 210 to process the subscriber's call processing and other additional services for supporting the public and private mobile network services, and to process various interfaces for interworking with the mobile gateway 112. do.

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

Accordingly, the pBSC 113 uses this identification information to distinguish whether the originating call is a call requiring a public mobile communication service or a call requiring a private mobile communication service.

That is, it is determined whether the outgoing signal of the wireless terminal transmitted from the pBTS 210 is an outgoing signal for requesting a public mobile communication service or a private outgoing mobile communication service. Bypass transparently to the BSC (40) of the mobile communication network, and if the private mobile communication service call is delivered to the mobile gateway 112 to provide a private mobile communication service.

For example, when the user inputs the telephone number "# 212" through the wireless terminal, the pBSC 113 includes the identifier "#" which wants to use the private mobile communication service, and thus wants to use the private mobile communication service. The call request signal including the telephone number "212" is transmitted to the mobile gateway 112 to determine that it is possible to make a call with the extension subscriber of the extension number "212".

When the user inputs the telephone number "# 02-212-8866", the pBSC 113 includes the identifier "#" which wants to use the private mobile communication service, and thus, wants to use the private mobile communication service. Determine and transmit a call request signal including the telephone number "02-212-8866" to the mobile gateway 112 and the public telephone network subscriber of the telephone number "02-212-8866" through the public telephone network through the wired switch 111 Make the call available.

In addition, when the user inputs the telephone number "# 016-212-8866", the pBSC 113 includes the identifier "#" which wants to use the private mobile communication service. Determining and transmitting the call request signal including the telephone number "016-212-8866" to the mobile gateway 112 through the public mobile communication network via the public telephone network through the wired switch 111 of "016-212-8866" Make a call with a public mobile service subscriber.

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

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

For example, if the field indicating whether a virtual landline number exists is set to 0, there is no virtual landline number. If it is set to 1, it indicates that there is a virtual landline telephone number corresponding to a MIN number. The phone number is stored.

Therefore, even when the virtual wireline telephone number is called in the mobile gateway 112, the corresponding wireless terminal can be called.

On the other hand, when any wireless terminal requests outgoing service through the pBTS (210) can be largely divided into two cases.

First, there may be a case where a call is requested using a private mobile communication service. In this case, as the caller ID transmitted from the pBTS 210 carries the MIN number assigned to the public mobile communication network, the mobile gateway 112 converts the caller ID into a virtual wired telephone number with reference to the database shown in FIG. 5. And sent through the wired switch (111).

On the other hand, when the private mobile communication service is not used, as the caller ID transmitted from the pBTS 210 carries the MIN number assigned to the public mobile communication network, the caller ID is transmitted to the BSC 40 of the public mobile communication network as it is. Do it.

In addition, the pBSC 113 manages the database 113c for the multiple incoming service in the memory 113a. That is, data about a virtual wired telephone number assigned to a wireless terminal to be called at the same time when a wired telephone number (for example, 02-XXX-YYYY) for which multiple calls are set up among the wired telephone terminals installed in the home and the corresponding telephone number is called. The base 113c is managed.

Accordingly, when the mobile gateway 112 inquires a virtual landline telephone number with multiple settings for a landline telephone number (for example, 02-XXX-YYYY) for which multiple calls are set, the corresponding landline telephone in the database 113c. Search for a number (e.g., 02-XXX-YYYY) to find a virtual phone number (02-CCC-DDDD) linked to that landline phone number and respond to the mobile gateway 112.

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

On the other hand, the database 113c established in the pBSC 113 stores information on any wired telephone number for which multiple incoming calls are set and the virtual wired telephone number of the wireless terminal to be called by multiple calls to the wired telephone number. . The database 113b and the database 113c may be implemented as one database.

In the wired / wireless interworking device 100 configured as described above, not only a wired telephone service for a wired telephone terminal, but also a call to a designated wireless terminal can be made when a virtual wired telephone is called. In addition, when making a wired telephone call, the mobile gateway 112 may make a wired / wireless simultaneous call to the desired terminal.

If there is a call from the PSTN 10 to the virtual wireline, the wired switch 111 calls the mobile gateway 112. The mobile gateway 112 calls the wireless terminal in the mobile zone 200 via the pBSC 113 and the pBTS 210 in response to the virtual wireline telephone number.

Then, when the incoming call comes from the wireless terminal, the call is connected. If no incoming call is received, terminate the service according to the fixed telephone service procedure.

FIG. 6 shows a procedure of calling a corresponding wired telephone or a wireless terminal when calling a wired telephone in the wired / wireless telephone interworking system shown in FIG. 3.

Referring to the reception path (P1, P2) shown in Figure 3 will be described in the incoming procedure.

When any subscriber station 11 calls an arbitrary landline telephone number through the PSTN 10, the wired switch 111 receives the corresponding landline telephone number through the PSTN 10 (S1) and receives the call. It is determined whether the number is a wired subscriber number (S2). If it is determined that the wired subscriber number is transmitted, the mobile gateway 112 transmits the wired subscriber line to the mobile gateway 112 (S3). On the other hand, if the determination result is not the wired subscriber number, the virtual subscriber line assigned to the wireless terminal is selected and transferred to the mobile gateway 112 (S4).

Mobile gateway 112 analyzes the phone number received from the wired switch (111). First, the mobile gateway 112 determines whether the corresponding telephone number is a multiple caller number in the database 112b shown in FIG. 4 (S5). If it is determined that the call is not a multiple caller number, the call is distributed to the wired subscriber (S6). Then, the wired terminal 250 will respond accordingly (S7).

On the other hand, as a result of determining whether the number is a multi-landing number, when the multi-landing number is first distributed to the wired subscriber (S8) (P1). In addition, the pBSC 113 requests a virtual wireline telephone number assigned to the wireline number (S9). Requesting a virtual wireline phone number from the mobile gateway 112 to the pBSC 113 is information that only indicates whether multiple destinations are set for an arbitrary wired terminal in the database 112b of the mobile gateway 112. Because only stored.

On the other hand, the pBSC 113 stores the direct information on the radio terminal for which the multiple destination is set for the wired number, the virtual corresponding to the radio terminal to be multiple incoming to the pBSC 113 from the mobile gateway 112 It requires a landline phone number.

Accordingly, the pBSC 113 retrieves the virtual wireline telephone number for the wireline telephone number from its database 113c and provides the mobile wireline 112 with the virtual wireline telephone number. The mobile gateway 112 distributes the call to the corresponding wireless terminal 220 through the pBSC 113 and the pBTS 210 (S10) (P2). Then, either the wired terminal 250 or the wireless terminal 220 will respond (S11). In addition, when the wired terminal does not respond, the mobile terminal can receive the incoming service anywhere in the mobile zone 200.

On the other hand, when determining whether it is a wired subscriber number (S2), if the determination result is not a wired subscriber number, the mobile gateway 112 selects the virtual subscriber line assigned to the wireless terminal 220 to the mobile gateway 112. The call is distributed to the corresponding wireless terminal through the pBSC 113 and the pBTS 210 (S12). Accordingly, the corresponding wireless terminal 220 will respond (S13).

7 shows a procedure for a wireless terminal subscriber to send to an external subscriber, FIG. 8 shows a procedure for a wireless terminal subscriber to send to an internal subscriber, and FIG. 9 is a flowchart for transmitting a wireless terminal subscriber to an external subscriber or internal subscriber. to be.

The incoming procedure of FIG. 9 will be described with reference to the incoming path P3 of FIG. 7 and the incoming path P4 of FIG. 8.

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

At this time, the pBSC 112 changes the caller ID (016-AAA-BBBB) assigned to the wireless terminal to the housekeeping wire number (for example, 02-CCC-DDDD) assigned to the wireless terminal (S23). ). In this case, the change of the caller ID refers to the database 113b illustrated in FIG. 5.

The mobile gateway 112 determines whether the calling number loaded from the wireless terminal is an external calling number (S24). In the case of an external caller number, only the call is stored in the message and transmitted to the wired switch 111. The wired switch 111 calls an external subscriber of the corresponding telephone number through the PSTN 10 (P3) (S26).

On the other hand, when it is determined whether the mobile gateway 112 is an external calling number (S24), when the determination result is not the external calling number, the internal subscribers 220, 240, and 260 in the mobile zone 200 are called (P4). (S27).

At this time, the charging process is enabled through the charging equipment (not shown) connected to the wired switch 111. At this time, the call between the internal subscribers made in the wired / wireless interworking device 100 in the mobile zone 200 may be operated free of charge without additional charge. In this case, the subscriber can talk between the internal subscribers without any additional charge.

10 and 11 illustrate a procedure in which an incoming call is rerouted when not in the mobile zone.

The rerouting procedure of FIG. 11 will be described with reference to the destination paths P5, P6, and P7A of FIG. 10.

When any external subscriber station 11 calls any wired telephone number through the PSTN 10, the wired switch 111 receives the wired telephone number through the PSTN 10 and the called telephone number is changed. It is determined whether it is a wired subscriber number (S31). If it is determined that the wired subscriber number is transmitted, the mobile gateway 112 transmits the wired subscriber line through the wired subscriber line (S32). On the other hand, if the determination result is not the wired subscriber number, the virtual subscriber line assigned to the wireless terminal is selected and transferred to the mobile gateway 112 (S33).

The mobile gateway 112 analyzes the telephone number received from the wired switch 111. At this time, the mobile gateway 112 has a database as shown in FIG. The mobile gateway 112 determines whether the corresponding telephone number is a multiple caller number in the database 112b (S34). If it is determined that the call is not a multiple destination number, only the wired telephone terminal is called, and the call is distributed to the wired subscriber (S35). On the other hand, if it is determined that the multiple caller number, the call is first distributed to the wired subscriber (S36). Next, the mobile gateway 112 requests the virtual number to the pBSC 113, receives the virtual number for the wired telephone number from the pBSC 113, the corresponding wireless terminal through the pBSC 113 and pBTS 210 The call is distributed to 220 (S37). On the other hand, when the mobile gateway 112 receives the wired telephone number through the virtual subscriber line assigned to the wireless terminal, the mobile gateway 112 distributes the call to the corresponding wireless terminal 220 through the pBSC 113 and the pBTS 210.

Then, if any of the wired terminal 250 or the wireless terminal 220 responds in the mobile zone 200, call processing is performed accordingly. Otherwise, the mobile zone 200 determines whether the subscriber is absent. It is determined (S38). When it is determined that the mobile zone 200 is absent due to no response of the wired terminal 250 or the wireless terminal 220 in the mobile zone 200, the mobile gateway 112 determines the wired switch 111 and the PSTN 10. And the wireless terminal 50a in the public mobile communication network through the BTS 50 in the public mobile communication network through the CDMA network 20 (S39). On the other hand, if the subscriber is in the mobile zone 200, but there is no response, the voice guidance message, such as "subscriber can not answer the call, please call the next time" can be sent ( S40).

Second Embodiment

12 is a system configuration diagram illustrating a concept of a wired / wireless telephone interworking service system according to another embodiment of the wired / wireless interworking device shown in FIG. 2.

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

In the drawing, the description of the mobile zone 200 including the pBTS 210 will be omitted since the foregoing description has been described with reference to FIG. 2.

In this embodiment, the mobile gateway 122 is used as a tandem switch, and the public switched telephone network (PSTN) 10 is connected to the trunk line interface Trunk of the mobile gateway 122 through N0.7 signaling.

The wired switch 121 is connected to a trunk line interface (Trunk) of the mobile gateway 122. 7 is connected via signaling and is installed to provide wireline telephone service to subscribers other than the mobile zone 200.

The wired switch 121 is a system for providing a wired telephone network to subscribers other than the mobile zone 200, and the mobile gateway 122 is a system for processing calls generated to wired and wireless subscribers in the mobile zone 200.

That is, the mobile gateway 122 processes a call for wired / wireless network service and mobile communication service to the wired / wireless subscribers 220-270 in the mobile zone 200, and the wired switch 121 is outside the mobile zone 200. It is a system that provides a wired telephone service to a wired subscriber (not shown).

For example, if a telephone station is set up for a large apartment complex, a pBTS 210 is installed and resides in an apartment complex located within a mobile zone 200 that can provide mobile communication services by the pBTS 210. Wired and wireless subscribers, and wired telephone service subscribers living in an apartment complex located outside of the mobile zone 200 that cannot provide mobile communication service because pBTS 210 is not installed and can provide only general wired telephone service. There can be.

In the case of such a large apartment complex, as the number of subscribers increases, it is difficult to provide wireline telephone service to subscribers in the mobile zone 200 and subscribers outside the mobile zone 200 in one mobile gateway 122. It may not be acceptable in capacity.

Accordingly, in the case of wired / wireless telephone subscribers in the mobile zone 200, the mobile gateway 122 provides the corresponding communication service, and a subscriber in the area outside the mobile zone 200 provides a separate wired switch 121. Through this communication service is to be provided.

Accordingly, when there is a call for any landline phone number through the PSTN 10, the mobile gateway 122 determines whether the phone number is an incoming call for its extension subscriber, and as a result, it is not an extension call. For example, if the subscriber's telephone number in the outside area of the mobile zone 200 is transmitted to the wired switch 121 by a tandem to provide the corresponding service in the wired switch 121.

The pBSC 123 connects the mobile gateway 122 and the pBTS 210 and is also connected to the BSC 40 of the public mobile communication network for a general public mobile communication service.

That is, the mobile gateway 122 directly connects the SLC interface to which the wireline telephone number is assigned to the subscriber's wireline telephone terminal 250 through a telephone line when the wireline telephone number is assigned to any subscriber for the wireline telephone service. . Accordingly, the wired telephone terminal 250 hears a dial tone provided by the mobile gateway 122 when the handset is hooked off for a call.

In addition, as the mobile gateway 122 provides a wireline telephone service to its extension subscriber, the mobile gateway 122 may assign a wireline telephone number to each subscriber within a range that the SLC interface can accommodate.

Here, the wired telephone number may be a wireline telephone number generally used to which the wireline telephone terminal 250 is connected at its end, and the virtual wireline telephone number to which the wireline telephone terminal 250 is not connected and merely a phone number is assigned. There may be.

Meanwhile, the mobile gateway 122 is connected to the pBSC 123 through E1 signaling, and performs a function of interworking a mobile communication service of the pBSC 123.

To this end, the mobile gateway 122 has a database 122b for a landline telephone number in the memory 122a. That is, as shown in Fig. 4, this database 112b stores information indicating whether or not it is a virtual telephone number for each telephone number, and information indicating whether or not it is registered with a multi-telephone service.

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

On the other hand, if it is set to 0 in the field indicating whether multiple calls are received, it indicates that the service is limited to an existing service calling a landline telephone terminal corresponding to the corresponding landline telephone number. It indicates that you are registered with the service.

Accordingly, the mobile gateway 122 needs specific information about the virtual wired telephone number corresponding to the wireless terminal to be called simultaneously with the wired telephone number when any wired telephone number registered with the multi-incoming service is called. The pBSC 123 requests the information.

Upon receiving information on the virtual telephone number of the wireless terminal connected to the wired telephone number from the pBSC 123, the virtual telephone number is called to the pBSC 123, and the pBSC 123 calls the virtual telephone number in the database 123b. The wireless terminal telephone number for the telephone number is found and the corresponding wireless terminal is called through the pBST 210.

On the other hand, when the mobile gateway 122 receives an outgoing service request from any wireless terminal from the pBSC 123, the mobile gateway 122 calls the subscriber of the calling number by carrying the caller ID and the caller ID of the wireless terminal received from the wireless terminal. .

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

In this case, the subscriber of the originating call may be an internal subscriber of the mobile gateway 122 or an external subscriber that may be called through the PSTN 10.

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

The pBSC 123 controls the pBTS 210 to process the subscriber's call processing and other additional services for supporting the public mobile network and the private mobile network service, and processes various interfaces for interworking with the mobile gateway 122. do.

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

Therefore, the pBSC 123 uses this identification information to distinguish whether the originating call is a call requiring a public mobile communication service or a private mobile communication service.

That is, it is determined whether the outgoing signal of the wireless terminal transmitted from the pBTS 210 is an outgoing signal for requesting a public mobile communication service or a private outgoing mobile communication service. Bypassing transparently to the BSC (40) of the mobile communication network, if the private mobile communication service call is delivered to the mobile gateway 122 to provide a private mobile communication service.

For example, when the user inputs the telephone number "# 212" through the wireless terminal, the pBSC 123 includes the identifier "#" which wants to use the private mobile communication service, and thus wants to use the private mobile communication service. The call request signal including the telephone number "212" is transmitted to the mobile gateway 122 to determine that it is possible to make a call with the extension subscriber of the extension number "212".

When the user enters the telephone number "# 02-212-8866", the pBSC 123 includes the identifier "#" which wants to use the private mobile communication service, and thus wants to use the private mobile communication service. It is determined that the call request signal including the telephone number "02-212-8866" to the mobile gateway 122 to enable the call to the public telephone network subscriber of the telephone number "02-212-8866" through the PSTN (10) do.

In addition, when the user inputs the telephone number "# 016-212-8866", the pBSC 123 includes the identifier "#" which wants to use the private mobile communication service. By determining and transmitting the call request signal including the telephone number "016-212-8866" to the mobile gateway 122 to enable the call with the public mobile service subscriber of "016-212-8866" via the PSTN (10). do. The identifier may be used in addition to "#".

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 by a public mobile communication network, and a virtual wireline telephone number assigned to the wireless terminal ( For example, a database 123c for 02-CCC-DDDD) is provided.

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

For example, if the field indicating whether a virtual landline number exists is set to 0, there is no virtual landline number. If it is set to 1, it indicates that there is a virtual landline telephone number corresponding to a MIN number. The phone number is stored.

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

On the other hand, when any wireless terminal requests outgoing service through the pBTS (210) can be largely divided into two cases.

First, there may be a case where a call is requested using a private mobile communication service. In this case, as the caller ID transmitted from the pBTS 210 is loaded with the MIN number given to the public mobile communication network, the caller ID is converted into a virtual wired telephone number with reference to the database 123c shown in FIG. It is sent to the way 122.

On the other hand, when the private mobile communication service is not used, as the caller ID transmitted from the pBTS 210, the MIN number assigned to the public mobile communication network is carried and the caller ID is transmitted to the BSC 40 of the public mobile communication network as it is. .

In addition, the pBSC 123 manages the database 123c for the multiple incoming service. That is, the wired telephone number (for example, 02-XXX-YYYY) set up with multiple incoming calls among the wired telephone terminals installed in the home and the virtual wired telephone number assigned to the wireless terminal to be called at the same time when the wired telephone number is called. The database 123c is managed.

Accordingly, when the mobile gateway 122 inquires a virtual landline telephone number with multiple settings for a landline telephone number (for example, 02-XXX-YYYY) with multiple incoming calls, the corresponding landline telephone in the database 123c. A number (eg, 02-XXX-YYYY) can be retrieved to find a virtual telephone number (02-CCC-DDDD) linked to that landline 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 multi-incoming service. The database 122b constructed in the mobile gateway 122 stores information on whether or not an arbitrary landline telephone number has been multiplexed and a virtual wireline telephone number assigned to each wireless terminal.

On the other hand, the database 123c constructed in the pBSC 123 stores information on an arbitrary landline telephone number for which multiple incoming calls are set and a virtual wireline telephone number of a wireless terminal to be called by multiple calls to the landline telephone number. .

In the wired / wireless interworking device 100 configured as described above, not only a wired telephone service for a wired telephone terminal, but also a call to a designated wireless terminal is possible when a virtual wired telephone is called. In addition, when a wired telephone call is made, the mobile gateway 122 may make a wired / wireless simultaneous call to the desired terminal.

When there is a call from the PSTN 10 to the virtual wireline, the mobile gateway 122 calls the wireless terminal in the mobile zone 200 through the pBSC 123 and the pBTS 210 in response to the virtual wireline number. .

Then, when the incoming call comes from the wireless terminal, the call is connected. If no incoming call is received, terminate the service according to the fixed telephone service procedure.

13 and 14 illustrate a procedure of simultaneously receiving a landline telephone and a wireless terminal during a landline telephone call.

The reception procedure will be described with reference to the reception paths P7 and P8 illustrated in FIG. 13 and the flowchart illustrated in FIG. 14.

When any subscriber station 11 calls any landline telephone number through the PSTN 10, the mobile gateway 122 calls the landline telephone number through the PSTN 10 and the received telephone number is mobile. It is determined whether the gateway 122 is an incoming call for the extension subscriber (S101). If it is determined that the incoming call is not an extension, the transmission is transmitted to the wired switch 121 by Tandem (S102). On the other hand, in case of an incoming call, the mobile gateway 122 analyzes the telephone number received from the PSTN 10. At this time, the mobile gateway 122 can determine whether the corresponding telephone number is a landline telephone number and whether it is a multiple destination number through a database as shown in FIG. 4.

First, it is determined whether it is a wired subscriber telephone number (S103). If the determination result is not the wired subscriber number, the virtual wired telephone number is called to the pBSC 123 because it is the wireless subscriber number. The pBSC 123 finds the telephone number of the wireless terminal corresponding to the virtual wired telephone number and distributes the call to the corresponding wireless terminal 220 through the pBTS 210 (S104). Then, the corresponding wireless terminal 220 will respond (S105).

On the other hand, in the determination result, in the case of a wired subscriber number, it is determined whether the wired / wireless multiple-calling is a set phone number (S106). As a result of determining whether the number is a multiple call number, if the call is not a multiple call number, the call is distributed to the wired subscriber (S111). Accordingly, the wired terminal 250 will respond (S112). However, in the case of a multiple destination number, first, the call is distributed to the wired subscriber (S106). When the virtual telephone number of the wireless terminal connected to the telephone number is requested to the pBSC 123 and the virtual telephone number is received from the pBSC 123, the virtual telephone number is called to the pBSC 123. The pBSC 123 finds the telephone number of the wireless terminal corresponding to the virtual telephone number and distributes the call to the corresponding wireless terminal 220 through the pBTS 210 (S109). Then, either the wired terminal 250 or the wireless terminal 220 will respond (S111).

15 shows a procedure for a wireless terminal subscriber to send to an external subscriber, FIG. 16 shows a procedure for a wireless terminal subscriber to send to an internal subscriber, and FIG. 17 is a flowchart for transmitting a wireless terminal subscriber to an external subscriber or internal subscriber. to be.

The incoming procedure of FIG. 17 will be described with reference to the incoming route P9 of FIG. 15 and the incoming route P10 of FIG.

The other terminal number (eg, 031-ZZZ-ZZZZZ, or 02-XXX-XXXX) is called from the wireless terminal 220 (eg, 016-AAA-BBBB) (S121). The outgoing signal generated by the wireless terminal 220 is transferred to the mobile gateway 122 via the pBTS 210 and the pBSC 123 (S22).

At this time, the pBSC 123 changes the 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 the calling number loaded from the wireless terminal is an external calling number (S124). As a result of the determination, if the caller is an external caller, the external subscriber of the corresponding telephone number is called through the PSTN 10 (P9) (S125).

On the other hand, when it is determined whether the mobile gateway 112 is an external calling number (S124), when the determination result is not the external calling number, the internal subscribers 220, 240, and 260 in the mobile zone 200 are called (P10). (S126).

At this time, the charging process is enabled through the charging equipment (not shown) connected to the tandem mobile gateway 122.

At this time, the call between the internal subscribers made in the wired / wireless interworking device 100 in the mobile zone 200 may be operated free of charge without additional charge. In this case, the subscriber can talk between the internal subscribers without any additional charge.

18 and 19 show a procedure in which an incoming call is rerouted when not in the mobile zone.

The rerouting procedure of FIG. 19 will be described with reference to the destination paths P11, P12, and P13 of FIG. 18.

When any subscriber station 11 calls any landline telephone number through the PSTN 10, the mobile gateway 121 calls the landline telephone number through the PSTN 10, and the received telephone number is mobile. It is determined whether the gateway 121 is an incoming call for the extension subscriber (S131). As a result of the determination, if the call is not an internal call, the signal is transmitted to the wired switch in tandem (S132).

On the other hand, in case of an incoming call, the mobile gateway 122 analyzes the telephone number received from the PSTN 10. At this time, the mobile gateway 122 can determine whether the corresponding telephone number is a wired telephone number and whether it is a multiple destination number through a database that it has.

First, it is determined whether the landline subscriber telephone number (S133). As a result of the determination, in the case of the wired subscriber number, it is determined whether the wired / wireless multi-calling is a set phone number (S134). As a result of the determination, if it is not the multiple caller number, the call is waited until the corresponding wired terminal is answered in the state of distributing the call only to the wired subscriber (S135). On the other hand, if it is determined that the multiple caller ID, the call is first distributed to the wired subscriber (S136). Then, the virtual number is requested to the pBSC 123, the virtual number is received from the pBSC 123, and the call is distributed to the corresponding wireless terminal 220 through the pBSC 123 and the pBTS 210 (S137). On the other hand, when the mobile gateway 121 receives the wired telephone number through the virtual subscriber line assigned to the wireless terminal, the mobile gateway 121 distributes the call to the corresponding wireless terminal 220 through the pBSC 123 and the pBTS 210.

Then, if any of the wired terminal 250 or the wireless terminal 220 responds in the mobile zone 200, call processing is performed accordingly. Otherwise, the mobile zone 200 determines whether the subscriber is absent. It is determined (S138). If it is determined that the mobile zone 200 is absent due to no response of the wired terminal 250 or the wireless terminal 220 in the mobile zone 200, the PSTN 10 and the CDMA network 20 in the mobile gateway 112. In step S139, the wireless terminal 50a in the public mobile communication network is called through the BTS 50 in the public mobile communication network. If there is no response even though it is in the mobile zone 200, a voice guidance message, such as "the subscriber is unable to answer the call, please call me" may be sent (S140).

Third Embodiment

20 is a system configuration diagram illustrating a concept of a wired / wireless telephone interworking service system according to another embodiment of the wired / wireless interworking device shown in FIG. 2.

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

In the drawing, the description of the mobile zone 200 including the pBTS 210 will be omitted since the foregoing description has been described with reference to FIG. 2.

The collective exchange 131 performs a call for wired telephone network service and a mobile communication service to the wired / wireless subscribers 220-270 in the mobile zone 200, and the wired subscriber outside the mobile zone 200 (not shown). It is a system that provides wired telephone service.

For example, when installed in a small apartment complex, pBTS 210 is installed and wired / wireless telephones to wired and wireless subscribers residing in the dong located in mobile zone 200 where pBTS 210 can provide wireless service. In addition to providing interworking services, general fixed line telephone services are also provided to wireline telephone subscribers who reside in the outside of the mobile zone 200 that cannot receive mobile communication services by the pBTS 210. .

The pBSC 133 connects the group exchange 131 and the pBTS 210 and is also connected to the BSC 40 of the public mobile communication network for general public mobile communication service.

In the embodiment, the mobile gateway and the wired switch are implemented as one group switch 131. The public switched telephone network (PSTN) 10 signals N0.7 to the trunk line interface (Trunk) of the group switch 131. Is connected through.

The wired switch 111 is connected to each wired telephone terminal (023, 250, 27) through a telephone line through a subscriber line card (SLC) interface.

That is, when allocating a landline telephone number to an arbitrary subscriber for landline telephone service, the collective exchange 131 directly connects the SLC interface to which the landline telephone number is assigned to the subscriber's landline telephone terminal 250 through a telephone line. . Accordingly, the wired telephone terminal 250 hears a dial tone provided by the collective exchange 131 when the telephone is hooked off for the call.

In addition, as the group exchange 131 provides a wireline telephone service to its extension subscriber, the group exchange 131 may allocate a wireline telephone number to each subscriber within a range that the SLC interface can accommodate.

Here, the wired telephone number may be a wireline telephone number generally used to which the wireline telephone terminal 250 is connected at its end, and the virtual wireline telephone number to which the wireline telephone terminal 250 is not connected and merely a phone number is assigned. There may be.

Meanwhile, the group exchange 131 is connected to the pBSC 132 through E1 signaling and performs a function of interworking a mobile communication service of the pBSC 132.

To this end, the collective exchange 131 has a database 131b for wireline numbers in the memory 131a. That is, as shown in Fig. 4, the database 131b stores information indicating whether or not it is a virtual telephone number for each telephone number, and information indicating whether or not it is registered with a multi-telephone service.

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

On the other hand, if it is set to 0 in the field indicating whether multiple calls are received, it indicates that the service is limited to an existing service calling a landline telephone terminal corresponding to the corresponding landline telephone number. It indicates that you are registered with the service.

Accordingly, when the group switch 131 is called any wired telephone number registered with the multi-telephone service, specific information about the virtual wired telephone number corresponding to the wireless terminal to be called simultaneously with the wired telephone number is needed. The pBSC 132 requests the information.

When receiving information on the virtual telephone number of the wireless terminal connected to the wired telephone number from the pBSC 132, the virtual telephone number is called to the pBSC 132. The pBSC 132 finds the wireless terminal telephone number corresponding to the virtual telephone number in the database and calls the corresponding wireless terminal through the pBST 210.

Meanwhile, when the collective exchange 131 receives an outgoing service request from any wireless terminal through the pBSC 132, the collective exchange 131 carries the calling number and the caller ID of the wireless terminal received from the wireless terminal to call the subscriber of the calling number. do.

At this time, the caller ID of the wireless terminal delivered to the group exchange 131 is a virtual wireline number (for example, 02-CCC-DDDD) assigned to the wireless terminal.

In this case, the subscriber of the originating call may be an internal subscriber of the collective exchange 131 or an external subscriber which may be called through the PSTN 10.

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

The pBSC 132 controls the pBTS 210 to process the subscriber's call processing and other additional services for supporting the public and private mobile network services, and processes all interfaces for interworking with the group exchange 131. do.

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

Accordingly, the pBSC 113 uses this identification information to distinguish whether the originating call is a call requiring a public mobile communication service or a call requiring a private mobile communication service.

That is, it is determined whether the outgoing signal of the wireless terminal transmitted from the pBTS 210 is an outgoing signal for requesting a public mobile communication service or a private outgoing mobile communication service. Bypass transparently to the BSC (40) of the mobile communication network, and if the private mobile communication service call is delivered to the group exchange 131 to provide a private mobile communication service.

For example, when the user enters the telephone number "# 212" through the wireless terminal, the pBSC 132 includes the identifier "#" which wants to use the private mobile communication service, and thus wants to use the private mobile communication service. The call request signal including the telephone number " 212 " is transmitted to the collective exchange 131 so that the call can be made with the extension subscriber of the extension " 212 ".

When the user enters the telephone number "# 02-212-8866", the pBSC 132 includes the identifier "#" which wants to use the private mobile communication service. Therefore, the pBSC 132 wants to use the private mobile communication service. By determining and transmitting the call request signal including the telephone number "02-212-8866" to the collective exchange 131, the user can make a call with the public telephone network subscriber of the telephone number "02-212-8866" through the PSTN 10. .

In addition, when the user inputs the telephone number "# 016-212-8866", the pBSC 132 includes the identifier "#" that wants to use the private mobile communication service. Determining and transmitting a call request signal including the telephone number "016-212-8866" to the group exchange 131 to allow a call with the public mobile communication service subscriber of "016-212-8866" via the PSTN 10. do.

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

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

For example, if the field indicating whether a virtual landline number exists is set to 0, there is no virtual landline number. If it is set to 1, it indicates that there is a virtual landline telephone number corresponding to a MIN number. The phone number is stored.

Therefore, even when the virtual wireline telephone number is called at the collective exchange 131, the corresponding wireless terminal can be called.

On the other hand, when any wireless terminal requests outgoing service through the pBTS (210) can be largely divided into two cases.

First, there may be a case where a call is requested using a private mobile communication service. In this case, as the caller ID transmitted from the pBTS 210 carries the MIN number assigned to the public mobile communication network, the caller ID is converted into a virtual wired telephone number with reference to the database shown in FIG. To send.

On the other hand, when the private mobile communication service is not used, as the caller ID transmitted from the pBTS 210 carries the MIN number assigned to the public mobile communication network, the caller ID is transmitted to the BSC 40 of the public mobile communication network as it is. .

In addition, the pBSC 132 manages the database 132c for the multiple incoming service in the memory 132a. That is, data about a virtual wired telephone number assigned to a wireless terminal to be called at the same time when a wired telephone number (for example, 02-XXX-YYYY) for which multiple calls are set up among the wired telephone terminals installed in the home and the corresponding telephone number is called. The base 132c is managed.

Accordingly, when the group exchange 131 inquires a virtual landline telephone number with multiple settings for a landline telephone number with multiple incoming calls (for example, 02-XXX-YYYY), the corresponding landline telephone number in the database (eg For example, by searching for 02-XXX-YYYY, a virtual telephone number (02-CCC-DDDD) linked to the landline telephone number can be found and responded to the group exchange 131.

That is, databases 131b and 132c are constructed in each of the collective exchange 131 and the pBSC 132 for the multiple incoming service. The database established in the collective exchange 131 stores information on whether an arbitrary landline telephone number has been multiplexed and the virtual wireline telephone number assigned to each wireless terminal.

On the other hand, the database established in the pBSC 132 stores information on any wired telephone number for which multiple incoming calls are set, and a virtual wireline telephone number of a wireless terminal to be called by multiple calls to the wired telephone number.

In the wired / wireless interworking device 100 configured as described above, not only a wired telephone service for a wired telephone terminal, but also a call to a designated wireless terminal can be made when a virtual wired telephone is called. In addition, when a wired telephone call is made, the collective switch 131 may make a wired / wireless simultaneous call to the desired terminal.

When there is a call from the PSTN 10 to the virtual wired telephone, the collective exchange 131 calls the wireless terminal in the mobile zone 200 through the pBSC 132 and the pBTS 210 in response to the virtual wired telephone number. .

Then, when the incoming call comes from the wireless terminal, the call is connected. If no incoming call is received, terminate the service according to the fixed telephone service procedure.

21 and 22 illustrate a procedure of simultaneously receiving a landline telephone and a wireless terminal during a landline telephone call.

The reception procedure will be described with reference to the reception paths P14 and P15 shown in FIG.

When any subscriber station 11 calls an arbitrary landline telephone number through the PSTN 10, the group exchange 131 receives the corresponding landline telephone number through the PSTN 10 and analyzes the telephone number. At this time, the group exchange 131 determines whether the corresponding telephone number is a wired subscriber number (S201). If it is determined that the wired subscriber number is not the wireless terminal subscriber, the call is distributed to the corresponding wireless terminal through the pBSC 132 and the pBTS 210 (S202). Accordingly, the wireless terminal 220 will respond (S203).

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

However, when the group switch 131 determines whether it is a multiple caller number or not, the group switch 131 first distributes a call to a wired subscriber (S207) (P14). Then, the virtual number is requested to the pBSC 132, the virtual number retrieved from the pBSC 132 is received, and the call is distributed to the corresponding wireless terminal 220 through the pBSC 132 and the pBTS 210 (S208) (P15). ). Then, either the wired terminal 250 or the wireless terminal 220 will respond (S209). In addition, when the wired terminal does not answer, the wireless terminal may receive the incoming service anywhere in the mobile zone 200.

On the other hand, when determining whether it is a multiple call number (S202), if the determination result is not a multiple call number, the call is distributed to the corresponding wireless terminal through the pBSC 132 and pBTS 210 (S206). Accordingly, the wireless terminal 220 will respond (S207).

23 shows a procedure for a wireless terminal subscriber to send to an external subscriber, FIG. 24 shows a procedure for a wireless terminal subscriber to send to an internal subscriber, and FIG. 25 is a flowchart of a wireless terminal subscriber for sending to an external subscriber or internal subscriber. to be.

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

The other terminal number (for example, 031-ZZZ-ZZZZZ, or 02-XXX-XXXX) is called from the wireless terminal 220 (for example, 016-AAA-BBBB) (S211). The outgoing signal generated by the wireless terminal 220 is transmitted to the group exchange 131 via the pBTS 210 and the pBSC 132 (S212).

At this time, the pBSC 132 changes the caller ID (016-AAA-BBBB) assigned to the wireless terminal to a housekeeping wire number (for example, 02-CCC-DDDD) assigned to the wireless terminal (S213). ). In this case, the change of the caller ID refers to the database 132b shown in FIG. 5.

The collective exchange 131 determines whether the calling number loaded from the wireless terminal is an external calling number (S214). In the case of an external call number, the external subscriber of the corresponding phone number is called through the PSTN 10 (P16) (S215).

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

At this time, the charging process is enabled through the charging equipment (not shown) connected to the group exchange 131. At this time, the call between the internal subscribers made in the wired / wireless interworking device 100 in the mobile zone 200 may be operated free of charge without additional charge. In this case, the subscriber can talk between the internal subscribers without any additional charge.

26 and 27 show a procedure in which an incoming call is rerouted when not in the mobile zone.

The rerouting procedure of FIG. 27 will be described with reference to the destination paths P18, P19, and P20 of FIG. 26.

When any subscriber station 11 calls any landline telephone number through the PSTN 10, the group exchange 131 receives the landline telephone number through the PSTN 10 and analyzes the called telephone number. . At this time, the group exchange 131 determines whether the corresponding telephone number is a wired subscriber number (S221). If the determination result is a wired subscriber number, the group exchange 112 determines whether the corresponding telephone number is a multi-landing number in the database as shown in FIG. 4 (S222). If the determination result is not a multiple caller number, the call is distributed to the wired subscriber (S223). However, as a result of the determination, in the case of the multiple caller number, the call is first distributed to the wired subscriber (P18) (S224). Next, the collective exchange 131 requests the virtual number to the pBSC 132, receives the virtual number for the wired telephone number from the pBSC 132, the corresponding wireless terminal through the pBSC 132 and pBTS 210 The call is distributed to 220 (P19) (S225). On the other hand, when determining whether it is a wired subscriber number (S221), if the determination result is not a wired subscriber number, the call is distributed to the corresponding wireless terminal through the pBSC 132 and the pBTS 210.

Then, if any of the wired terminal 250 or the wireless terminal 220 responds in the mobile zone 200, call processing is performed accordingly. Otherwise, the mobile zone 200 determines whether the subscriber is absent. It is determined (S226). If it is determined that the mobile zone 200 is absent due to no response of the wired terminal 250 or the wireless terminal 220 in the mobile zone 200, the collective switch 131 may use the PSTN 10 and the CDMA network 20. In step S227, the wireless terminal 50a in the public mobile communication network is called through the BTS 50 in the public mobile communication network. If there is no response even though it is in the mobile zone 200, a voice guidance message such as "the subscriber is unable to answer the call, please make a call next time" may be transmitted (S228).

According to the present invention, when a subscriber is subscribed to a wireline service by a wired / wireless interworking device, a private mobile communication network operated by the wired / wireless interworking device through a designated wireless terminal at the time of calling the wireline telephone terminal as well as the existing wireline telephone service. Incoming calls can be made from within, providing mobility to landline telephone services.

In addition, by operating a virtual wired telephone number in the form of a general landline telephone service telephone number, it is possible to receive a call made by an external subscriber to a landline telephone number through its wireless terminal, and caller ID when calling to an external subscriber. Is transmitted to the virtual wired telephone number, the subscriber side can provide the same effect as having the wired telephone terminal in the eyes of the external subscriber even without actually installing the wired telephone terminal. In addition, external subscribers may also receive telephone service according to the billing rate of the wireline telephone service when calling the subscriber's wireless terminal.

In addition, even if a subscriber simultaneously uses a wired telephone service and a mobile communication service, the internal subscriber may not be charged, thereby reducing the burden of duality of billing.
