2. Description of the Related Art FIG. 4 is a block diagram of the prior art. In mobile communications, exchanges for mobile subscribers such as mobile phones and mobile phones that make and receive calls change as the mobile subscriber moves, but a subscriber file that records subscriber data such as subscriber attributes is installed. The stations are fixed for each mobile subscriber and are called home memory stations. Further, the mobile subscriber registers the current location information in the subscriber file via the mobile switchboard at the destination as the mobile subscriber moves.

FIG. 4 shows a mobile communication network constructed as described above. A mobile subscriber 31 such as an automobile telephone 31a or a mobile telephone 31b shown in FIG. A location registration operation and a connection operation when a call is transmitted to the subscriber 41 of the fixed communication network 40 when the mobile terminal is in the wireless area of the mobile switching center 23 will be described.

[0006] A mobile subscriber 31 is connected to a mobile trunk (hereinafter referred to as MBWT) 27 of a mobile exchange 23 via a radio base station 30 and a radio control station 29. The current location is registered in the subscriber file 22 of the home memory station 21.

Next, when the mobile subscriber 31 dials the number of the fixed station subscriber 41, the control unit 24 controls the communication network (NW) 25.
To connect a MBWT 27 and a trunk (hereinafter, referred to as TRK) 26, and then a gateway switch 28 of the mobile communication network 20.
And a fixed station subscriber 41 via a gateway switch 42 of the fixed communication network 40.
Connect to Thus, communication between the mobile subscriber 31 and the fixed station subscriber 41 is performed.

Next, the operation of a mobile termination connection in which a connection is made from the fixed station subscriber 41 to the mobile subscriber 31 will be described. The fixed station subscriber 41 uses a mobile communication identification number (for example, “03”) as a predetermined number for mobile communication.
When "0") + mobile subscriber number "is dialed, the fixed station subscriber 41 is connected to the gateway exchange 28 of the mobile communication network 20 via a not-shown exchange and a gateway exchange 42 in the fixed communication network 40. . The gateway switch 28 accesses the home memory station 21 of the mobile subscriber 31 based on the received mobile subscriber number, and confirms the current location of the called mobile subscriber 31 based on the subscriber file 22.

As a result, when it is confirmed that the called mobile subscriber 31 is within the wireless area of the mobile exchange 23, the gateway exchange 28 connects to the mobile exchange 23.

In FIG. 2, a fixed communication network, a radio control station,
Although the radio base station and the mobile subscriber are not shown,
These positional relationships in the mobile communication network are the same as those shown in FIG. Since the location registration operation of the mobile subscriber is the same as that of the prior art, the description is omitted, but the current location information of the mobile subscriber is stored in the general subscriber data storage of FIG. 3 (1) for each mobile subscriber. It is stored in the unit 2b.

Hereinafter, an embodiment of the present invention will be described with reference to FIG. It is assumed that a plurality of mobile subscribers (not shown) form a group, and the numbers of the mobile subscribers are A01 to A.
m, B01-Bn, etc., mobile subscribers A01-Am are group G1, and mobile subscribers B01-Bn are group G.
2. It is to be noted that, as the mobile subscriber number, for example, a seven-digit number is generally used, and the group identification number is basically composed of a number. Use symbols.

The group registration display section 3a of each mobile subscriber in the subscriber file 2 shown in FIG. 3A shows, for example, "1" for a subscriber constituting a group and "1" for a subscriber not constituting a group. 0 "is stored, and when forming a group, the group identification number is stored in the group identification number storage unit 3b.

These storages are performed in advance by offline processing or the like. In FIG. 3A, a plurality of mobile subscribers A0
1, A02 and the like constitute a group, and a group identification number G
An example where 1 is given is shown.

The detailed information of each group is centrally stored in the group information table 5 of any one of the group home memory stations 4 installed in the mobile communication network.

FIG. 3B is a detailed example of the group information table 5. In the figure, information of two groups G1 and G2 is described, but the group identification number G is stored in the group identification number storage unit 5a and the mobile subscriber number storage unit 5b.
It is shown that one group includes the mobile subscribers A01, A02 and the like.

Further, when the mobile subscribers A01, A02, etc. communicate using the abbreviated dial numbers in the group G1, the intra-group numbers are "001", "002", etc., respectively, by the intra-group number storage unit 5c. The representative display section 5d indicates that the representative subscriber of the group G1 is the mobile subscriber A01.

In the service registration contents 5e, service functions to be provided to each mobile subscriber are stored, and functions to be provided are indicated by "1" and functions not to be provided are indicated by "0". In the example of FIG. 3 (2), the group G1 receives the representative call, the representative billing, and the abbreviated dialing within the group.
FIG. 2 shows an example in which only the representative incoming call is performed. The representative of the group need not be the mobile subscriber stored at the head of each group, and the representative of group G2 is mobile subscriber B02.

FIG. 3 (3) shows an example of the configuration of the group home memory station identification table 8 provided in the mobile switching center 6 for performing connection processing for mobile subscribers. The identification number storage unit 8a and the code of the group home memory station in which information of the group having the group identification number is stored are stored correspondingly. The group home memory station code 8b is given a code corresponding to the configuration of the mobile communication network.
This code is used when the mobile switching center 6 connects to the group home memory station 4.

An embodiment of the group connection processing according to the present invention will be described with reference to FIG. 2 on the premise of the configuration shown in FIG. First, a representative connection using a group identification number will be described. In this case, the subscriber of the fixed communication network (not shown) dials a representative connection number of a predetermined mobile subscriber group. The representative connection number is configured as “mobile communication identification number (for example,“ 030 ”) + representative connection identification code (for example, #) + group identification number (for example, G1)”. It is received by the TRK 11 of the mobile exchange 6 via the gateway exchange.

The representative connection number is sent from the TRK 11 to the control unit 7 via a path (not shown). When the control unit 7 identifies the representative connection from the received representative connection identification code, it identifies the group home memory station. The table 8 is accessed to confirm, for example, "XXX1" as the code of the group home memory station in which the received group information of the group identification number G1 is stored.

The group home memory station code "XX"
X1 "is sent to the group service processing section 9, and the group service processing section 9 uses this code to access the group information table 5 of the group home memory station 4 and confirm the representative subscriber of the group identification number G1. The confirmation is performed by searching for a mobile subscriber in which "1" is stored in the representative display section 5d of FIG. 3 (2).
In the example, the mobile subscriber number A01 is detected as a representative.

The group service processing unit 9 notifies the control unit 7 of the result of the above confirmation, and the control unit 7 calls the mobile subscriber number A01 via the MBWT 12 as in the case of the normal incoming connection.

As a result of the mobile subscriber A01 answering and making a call with the fixed station subscriber, a request for the fixed station subscriber to communicate with another mobile subscriber in the same group, for example, the mobile subscriber A02. In this case, the representative mobile subscriber A01 dials the mobile subscriber number of the transfer destination after hooking (the case of using the in-group speed dial will be described later).

Mobile subscriber A02 is mobile subscriber A01.
Is not necessarily located in the same wireless area as that of the home memory station 1.
After accessing and confirming the subscriber file 2 of the above, normal connection processing for the mobile subscriber is performed. Mobile subscriber A
02 responds and the mobile subscriber A01 notifies the user of the transfer and disconnects, and a call is started between the fixed station subscriber and the mobile subscriber A02. This transfer processing is usually performed in the fixed station. Since the transfer process is basically the same as the known transfer process, detailed description thereof will be omitted.

Next, a description will be given of a representative connection in which, for example, all connection requests to mobile subscribers A01 to Am belonging to the group G1 are connected to the representative mobile subscriber A01 without using the group identification number. In this case, the dial content of the fixed station subscriber is the same as that for a single mobile subscriber.

A fixed station subscriber (not shown) dials, for example, a mobile subscriber number A02, and the mobile subscriber A0
When the mobile exchange 6 in which the mobile station 2 is located receives the dial, the control unit 7 accesses the subscriber file 2 of the home memory station 1 of the mobile subscriber A02 in a normal connection process, and the mobile subscriber A02. At this time, the mobile subscriber A02 simultaneously identifies that the mobile subscriber A02 is a group subscriber belonging to the group identification number G1.

Next, the control unit 7 accesses the group information table 5 of the group home memory station 4 via the group service processing unit 9, and stores the representative connection function storage unit 5e _{1 of the} mobile subscriber A02 belonging to the group identification number G1. Is “1”, and the representative display section 5
By d, it is confirmed that the representative subscriber is the mobile subscriber A01. As a result, the control unit 7 sets the representative mobile subscriber A0
1 is performed, but the subsequent operation is the same as in the case of the representative connection using the group identification number, and the description is omitted.

When the mobile unit A01 is connected to the representative mobile unit A01 and cannot be connected because the mobile unit A01 is busy or in a power-off state, the control unit 7 belongs to the group identification number G1. In addition, another mobile subscriber whose representative connection function is displayed as "1" is selected, and a connection is made to this.

Next, representative billing will be described. Representative billing is a service for billing representative subscribers the communication charges of mobile subscribers belonging to the same group. In general, representative billing is performed by charging each mobile subscriber and collectively charging the representative subscriber at the billing stage.However, for a mobile phone such as a mobile phone rented by the organizer at an event, etc. In a case where the communication fee is collectively charged to the representative subscriber, a method of charging the representative subscriber for each communication may be adopted. Hereinafter, the latter embodiment will be described.

Mobile subscriber A02 belonging to group G1
Is transmitted, the mobile exchange 6 of the serving station detects the call and accesses the subscriber file 2 of the home memory station 1. This access confirms that the mobile subscriber A02 has been registered as a group and that the group identification number is G1.

Next, the control unit 7 of the mobile switching center 6 checks the mobile subscriber A based on the group home memory station identification table 8.
The group home memory station identification number 02 is confirmed, and the group information table 5 of the group home memory station 4 is accessed. Because the representatives charging storage unit 5e ₂ of the mobile subscribers A02 group of the group information table 5 G1 is "1" is stored as shown in FIG. 3 (2), representatives reaffirmed this The number A01 is confirmed on the representative display section 5d.

The control unit 7 confirms the above and establishes a connection to the mobile subscriber A02.
The charge is stored in the subscriber data of the mobile subscriber A01.
Next, a description will be given of intra-group speed dial connection.

When mobile subscribers form a group,
It is convenient to use a group number with a small number of digits for connection within a group. The intra-group number storage unit 5c of the group information table 5 in FIG. 3 (2) stores the intra-group number assigned to each mobile subscriber in advance.

When the mobile subscriber A01 in the group G1 connects to the mobile subscriber A02 in the same group, the mobile subscriber A01 has a mobile subscriber number A02 having a large number of digits.
Instead, the in-group number is used as a speed dial number, and "speed dial identification code (for example, *) + speed dial number (" 002 ")" is dialed.

The control unit 7 of the mobile exchange 6 in which the mobile subscriber A01 is located accesses the subscriber file 2 of the home memory station 1 of the mobile subscriber A01, and the mobile subscriber A0.
1 is a group registered and the group identification number is G
Check that it is 1.

Next, the control section 7 identifies and accesses the group home memory station 4 by the group home memory station identification table 8, and stores the abbreviated dial number “002” of the group G1 by the in-group number storage section 5c of the group information table 5. Confirm that the mobile subscriber number is A02.

The group service processing section 9 which has received this information from the group information table 5 notifies the control section 7 which performs the connection processing of the mobile subscriber number A02, and the control section 7 performs the normal processing for the mobile subscriber A02. Make an incoming connection.

As described above, in the present invention, a group is composed of a plurality of mobile subscribers, and a representative connection or a representative billing for a representative subscriber in the group, a speed dial connection for a mutual call in the group, etc. Service can be provided.

The embodiment of the present invention has been described with reference to FIGS. 2 and 3. However, FIGS. 2 and 3 show only a part of the embodiment of the present invention. Needless to say, the present invention is not limited to the one shown in FIG.

For example, in FIG. 2, the home memory station 1, the group home memory station 4, and the station where the mobile switching center 6 is installed are separately illustrated, but the mobile subscriber is located within the wireless area of the home memory station. When the mobile station is located, the home memory station 1 and the mobile station 6 are installed at the same location. Needless to say, the group home memory station 4 may be installed in the home memory station 1 or the installation station of the mobile switching center 6.

In FIG. 2, the group home memory station identification table 8 and the group service processing section 9 are separately provided in the control section 7. However, even if these are integrated as the control section 7, the effect of the present invention can be obtained. Clearly, it will not change.

The subscriber file shown in FIG. 3A stores the mobile subscriber number as the mobile subscriber number storage unit 2a. When converted to other information for identifying the mobile subscriber, for example, address information, the address information is stored instead of the mobile subscriber number in the mobile subscriber number storage unit 2a. As a result, the effect of the present invention does not change.

Further, a part of the contents of the group information table shown in FIG.
Alternatively, even if the contents of the group home memory station identification table 8 are included in the group identification number storage unit 3, the effect of the present invention does not change.

[0060]

As described above, according to the present invention,
A group is formed by a plurality of mobile subscribers, and connection processing can be performed in units of groups, such as representative connection and representative billing for representative subscribers in the group, or abbreviated dial connection for mutual calls in the group. It is possible to greatly improve the convenience of the service function in the mobile communication system.
