As a database, information of mobile communication terminals (MS) 10, 40 to 46 and subscribers located in the area in which they are in charge is taken from the home location register (HLR) 22 and temporarily stored.

The service control point (SCP) 18 is a system for controlling a separate additional service on behalf of the exchange as the function of the exchange system is complicated and the additional service provided by the mobile communication network increases.

The service control point (SCP) 18 of the present invention is connected to the service provider's web page through the Internet network or the wireless network from an outgoing mobile communication terminal (MS) 10, 40 to 46, which is an arbitrary terminal, to determine the group number. When the subscriber telephone number list is requested to be registered, the MIN (Mobile Identification Number) along with the list of the group number is transmitted to the group number list DB 20 to be stored and managed. Here, as shown in FIG. 5, the group number defines a group of numbers capable of multi-access call processing with one terminal number, and the telephone number of the mobile communication terminal (eg, 011-200-1111) or the telephone number of the wired terminal (042-). 482-0000).

When any mobile communication terminal accesses the service provider's web page and requests to delete or change the subscriber's telephone number list of the group number, the service control point (SCP) 18 is linked with the web page to request the deletion or change of the terminal. The MIN is compared with the MIN of the terminal registering the group number stored in the group number list DB 20, and if the two values are the same, the subscriber telephone number list of the group number is deleted or changed.

The service control point (SCP) 18 connects the call to any number in the group number set in the originating mobile communication terminal (MS) 10 through the base station (BTS) 12 and the base station controller (BSC) 14. When requesting a request, the subscriber telephone number list of the group number including the number requesting the call connection is searched among the data registered in the group number list DB 20 and provided to the exchange (MSC) 16.

The group number list DB 20 stores not only the subscriber telephone number list composed of the group numbers delivered from the service control point (SCP) 18 as a database, but also stores the MIN information of the calling terminal that registered the group number. do. The group number list DB 20 also serves to provide a subscriber telephone number list of the group number stored in the service control point (SCP) 18.

The home location register (HLR) 22 is a database that stores permanent information, location information, and additional service information of mobile communication terminals (MSs) 10, 40 to 46, and subscribers. It interacts with visitor location registers (VLR) 16, 24, 26 to perform various functions related to call processing and supplementary services and to control services.

To ensure that the call is processed.

2 is a flowchart briefly illustrating a process of registering a group number list through a service control point in a group number service method of a mobile communication network according to the present invention. 1 and 2, a procedure for registering a group number list in a mobile communication network according to the present invention is as follows.

Any mobile communication terminal (MS) 10 is connected to the service provider's web page via the Internet network or wireless data network and requests registration of the subscriber's telephone number list of the group number (S10).

A subscriber prepares a list of subscriber telephone numbers of a group number in order to receive a group number addition service of the present invention using a mobile communication network on an application of a web page. At this time, the group number list refers to a list of telephone numbers for multi-access call processing up to the remaining numbers grouped into one number. Alternatively, the subscriber's telephone number list of the group number created by the outgoing mobile communication terminal (MS) 10 for receiving the group number addition service is transmitted to the service provider's web page through the Internet network or the wireless data network.

In the web page of the service provider, it is determined whether to store the group number list (S14).

As a result of the determination in S14, when the subscriber or the mobile communication terminal (MS) 10 selects the storage, the service control point (SCP) of the mobile communication network which operates in conjunction with the web page of the subscriber's telephone number list of the created / delivered group number. To 18. At this time, the service control point (SCP) 18 also receives the MIN of the terminal requesting the group number addition service.

The service control point (SCP) 18 transmits its MIN to the group number list DB 20 along with the subscriber's telephone number list of the transmitted group number, and stores and manages it (S16).

3 is a flowchart briefly illustrating a process of deleting or changing a group number list through a service control point in a group number service method of a mobile communication network according to the present invention. 1 and 3, a procedure for deleting or changing a group number list in a mobile communication network according to the present invention is as follows.

Any mobile communication terminal (MS) 10 is connected to the service provider's web page via the Internet network or wireless data network and requests to delete or change the subscriber's telephone number list of the group number (S20).

When any mobile communication terminal (MS) 10 requests the deletion or change of the group number list, the web page creates a subscriber's telephone number list of the group number to be deleted on the application program, or via the Internet network or a wireless data network. The subscriber's telephone number list of the group number to be changed is received. (S22)

The web page receives the MIN of the mobile communication terminal requesting the deletion or change of the group number list and transfers the MIN value to the service control point (SCP) 18. The service control point (SCP) 18 compares the input MIN with the same MIN values stored in the group number list DB 20 (S24). The delete or change request is received (S26).

Accordingly, the service control point (SCP) 18 receives the subscriber's telephone number list of the group number from the web page, and deletes or changes the group number list corresponding to the MIN in the group number list DB 20 (S28).

On the other hand, although not shown in the drawings, another method of deletion or change according to the present invention, when requesting the deletion or change of the group number list in S20, the web page inputs the MIN of the mobile communication terminal requesting the deletion or change of the group number list. Receive the MIN value to the service control point (SCP) 18. The service control point (SCP) 18 compares the input MIN with the same MIN values stored in the group number list DB 20, and if there is the same MIN value, the subscriber telephone of the group number corresponding to the corresponding MIN value. Search for a list of numbers and find them on a web page. When the web page deletes or changes the subscriber's telephone number list of the group number directly to the application for processing, the MIN registered in the group number list DB 20 through the service control point (SCP) 18 according to the request information. Delete or change the subscriber telephone number list of the group number of the value.

Therefore, the present invention provides a group number list DB (20) of a subscriber number list of a group number through a service control point (SCP) 18, which is an intelligent network server that is operated separately from an exchange to implement an additional service with a group number in a mobile communication network. ) Can be registered, deleted or changed. At this time, the service control point (SCP) 18 is connected to the web page of the service provider through the Internet or wireless network to perform the procedure of registering, deleting or changing the subscriber's telephone number list of the group number.

4 is a flowchart illustrating a process of connecting a call to a group number in a group number service method of a mobile communication network according to the present invention. 5 is a view showing a group number used in the present invention.

1, 4 and 5, according to the present invention, a call processing and call connection method for multi-accessing all numbers of a group number list with one number is as follows. Here, the calling mobile communication terminal is limited to 10, and the receiving mobile communication terminal which is processed by multi-access by the group number is limited to 40 to 46. The exchange also describes 16 as the outgoing exchange and 24 and 26 as the destination exchange.

First, when an arbitrary number in a preset group number is dialed in the originating mobile communication terminal (MS) 10, the service control point (SCP) 18 is transmitted through the base station (BTS) 12 and the base station controller (BSC) 14. Request a call connection to the corresponding number, for example, 018-300-1112 as shown in FIG. 5 (S30).

The service control point (SCP) 18 checks whether there is a group number list B including the numbers 018-300-1112 among the group number list data A, B, and C previously stored in the group number list DB 20. Search (S32).

As a result of the search in S32, when the group number list B including the number 018-300-1112 is found, the service control point 18 receives the subscriber telephone numbers included in the group number list B. -300-1111, 018-300-1112, 042-480-1234, 011-200-3333 are provided to the originating exchange (MSC) 16. (S34)

The calling exchange (MSC) 16 corresponds to the subscriber telephone numbers 016-300-1111, 018-300-1112, 011-200-3333 of the group number list B via the home location register (HLR) 22. The location information of the called terminal is found and routed based on the location information.

The originating exchange (MSC) 16 processes the call by multi-access with the terminating exchange (MSC) 24 in the region where the terminating mobile communication terminal (MS) 40 to 46 is located according to the routing information. (S38) S36 to Although not shown in the drawing at step S38, routing of the destination terminal location corresponding to 042-480-1234 is routed through the public switched telephone network (PSTN) connected by wire with the originating exchange (MSC) 16 and the wired exchange of this terminal. Call processing with multi access.

After the call is handled by the multi-access between the source and destination exchange (MSC) (16, 24, 26), it determines the established call connection state (S40) (base station controller (BSC) 28, 30) and base station (BTS) ( 32 through 38), call connection is performed as follows.

In other words, the MSC 24, 26 is connected between one called terminal, for example, the called mobile terminal of 42 and the calling terminal 10, among the subscriber telephone numbers in the group number processed by the multi-access. Performs call connection and releases the call connection of 40, 44, and 46 called terminals of the other subscriber's phone number (S42).

Alternatively, the MSC 24 or 26 may be connected to a caller between the first called mobile terminal, for example, the terminal 42 and the calling terminal 10, among the subscriber telephone numbers in the group number. The call connection of the called terminals 40, 44, 46 of the telephone number is continued. Accordingly, by the end button or the specific key button of the calling terminal 10, the MSC 24, 26 disconnects the call from the 42 called terminal and selects one of the remaining called terminals 40, 44, 46. It is possible to call with one and call connection. (S44)

Alternatively, the destination switching center (MSC) 24, 26 performs a multi-call call connection when at least two destination terminals in the subscriber number in the group number processed by the multi-access answer (S46). In addition, the call terminal 10 is connected to the incoming mobile communication terminals of 40, 44 to enable a three-way call.

In addition, in the service method of the present invention, when an outgoing mobile terminal (MS) 10 dials an arbitrary number within a preset group number with a specific key button in step S10, the base station (BTS) 12 and the base station controller ( BSC) requests the service control point (SCP) 18 to call a corresponding number. Then, the service control point (SCP) 18 determines that the call processing process is not a multi-access call processing process using the group number list, and sends only the number requesting the call connection to the MSC 16 to the home location register. After (HLR) 22 finds the location information of the called terminal of the corresponding number and routes it based, the call processing with the called exchanger (MSC) 24, 26 is performed.

On the other hand, although not shown in the drawing, the present invention does not perform a call connection anymore by failing the call processing if there is no destination terminal answered among the subscriber telephone numbers of the group number after the call processing in this multi-access. .

As described above, the present invention changes the MAH service to the caller center, and the subscriber telephone of the group number in which all the numbers in the group number list are multi-accessed from the caller terminal to the service control point of the mobile communication network with any number in the group number. You can freely register, delete or change the number list. Therefore, the present invention can freely register, delete, or change the subscriber list of the group number for call processing in the multi-access call service terminal of the mobile communication network.

The present invention also provides a called terminal registered as a group number by transmitting a list of subscriber telephone numbers and their location information to the exchange, regardless of which number in the group number the caller terminal calls from the service control point. Calls are handled with multiple access.

The biggest difference between the group number addition service and the MAH representative number addition service of the present invention is that the present invention multi-accesses all the phone numbers of the group number list even if a call connection request is made to any of the subscriber phone numbers included in the group number. Call processing is possible. However, the representative MAH additional service of the conventional MAH is capable of multi-access to all the telephones of the subscriber list of the representative number only when a call connection request is made to the representative number. Therefore, the present invention allows the caller to easily make a telephone call with the subscriber of the group number list to any number in the group number.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications are possible by those skilled in the art within the spirit and scope of the present invention described in the claims to be described later.
