It is a figure which shows the example of a table structure which records the subscriber number of a mobile device.

Hereinafter, the connection control of the mobile device in the designated area by the mobile communication system according to the present invention will be described with reference to FIGS.

First, in the mobile communication switching center MSC, the mobile station MS2 of the calling subscriber and the mobile station MS1 of the receiving subscriber designate the same subscriber group GN1 by the same means as the existing subscriber service registration control. By doing so, the service registration unit 10 displays the subscriber group number registration table shown in FIG. 5 (a) by the subscriber numbers MSI1, M of the mobile stations MS1, MS2.
The same group number GN1 is set corresponding to SI2.

Now, as shown in FIG. 2, when the mobile station MS1 moves from another radio zone to the radio zone LI1, the mobile station M1
The location registration request of S1 is sequentially sent to the mobile station MS1 → the radio base station BS1 → the exchange MSC in the same manner as in the well-known location registration control (the same figure).

When the exchange MSC receives the location registration request,
After updating the position number of the mobile unit MS1 by the position registration unit 20 by the existing means, the position number conversion table 2 of FIG. 5 (b) in consideration of the fact that a plurality of wireless zones are distributed in each area is stored in the position registration request signal. Area number AN1 indexed by position number LI1
Convert to.

Further, the same figure (a) previously registered as described above.
The subscriber group number registration table 1 is indexed by the subscriber number MSI1 of the location registration mobile unit in the location registration request signal and converted into the subscriber group number GN1, and the thus obtained subscriber group number GN1 is used. ) Table MSIH in the local mobile station record table 3 is indexed to obtain the service area record table MSIRTi, and then MSIRT
i is searched by the already converted area number AN1 to obtain the mobile unit recording table MSIRTj, and subsequently, the subscriber number MSI1 of the position registration mobile unit is recorded in an empty area in MSIRTj.

In such a state, the calling subscriber communicates with the mobile station located in the specific area AN1 from the mobile station MS2, that is, the dial number as shown in FIG. Dialing the area code + local area code, the mobile unit MS2 is operated by the same means as known connection control.
→ Wireless base station BS2 → Switching station MSC is sequentially connected (FIG. 2).

When the exchange MSC deciphers the special number (identification number) in the received dialed digits by the dial deciphering section 30 and determines that the service call is a service call for connecting to a designated area mobile station, it joins as shown in FIG. 5 (a). Group number registration table 1
Is indexed by the subscriber number MSI2 of the originating mobile station in the call origination request signal received together with the dialed number and converted into the subscriber group number GN1.

Subscriber group number GN1 thus obtained
Then, the table MSIH in the local mobile station record table 3 of FIG. 5 (c) is indexed to find the service area record table MSI.
Area RTAN1 consisting of the area code and local area code in the received dialed digits
To find the mobile device record table MSIRTj,
Then, the subscriber number MSI1 of the mobile station recorded in MSIRTj is read.

The subscriber number MSI1 thus obtained is treated in the same manner as the subscriber number of the communication partner dialed in a general outgoing call, and call control is performed by the incoming call control unit 40 (FIG. 2).
).

As a result, the mobile station MS1 is called by the known means via the radio base station BSI, and enters the mutual communication state by the subscriber response.

By such control, among the mobile stations located in the area AN1 designated by the calling subscriber from the mobile station MS2 by dialing, the mobile station M belonging to the same group GN1 as the calling subscriber.
Only S1 can be called.

Even if another subscriber MSi is located in the same area AN1, it is not called because the mobile station record table is different unless the subscriber group is GN1. Further, even if a plurality of subscribers of the same subscriber group GN1 are registered, they are not called because the mobile station recording table MSIRTj is different unless the areas where they are located are the same AN1.

In addition to the above embodiment, the following modifications are realized. (1) In addition to using the area code and local area code in the dialed number configuration shown in Fig. 4, it is necessary to use the postal code and other numbers that are easy to specify in the area by using the position number conversion table in Fig. 5 (b). It becomes possible by adding a conversion code such as a zip code.

(2) The calling subscriber omits the area designation numbers such as the area code and the local area code among the dialed numbers shown in FIG. 4 and dials, and the calling subscriber's position number LIi is as described above. Then, the location number conversion table of FIG. 5 (b) is indexed by this location number LIi to obtain the area number ANi, and by controlling this ANi as the area number dialed by the calling subscriber, It is possible to perform call control for mobile devices of the same subscriber group located in the same area. (3) When multiple mobile units of the same group are located in the area designated by the calling subscriber, call control is performed simultaneously for the multiple subscriber numbers recorded in the mobile unit record table of FIG. 5 (c). However, it is possible to speed up the call by connecting only to the responding subscriber and interrupting the call by the other subscribers. In addition, one subscriber is selected and called out from the plurality of subscriber numbers recorded in the mobile device record table under the optimum conditions, and if the result of the call is that there is no response from the other party, the next subscriber is sequentially selected and called. You may do it.

(4) In addition, when the subscriber number is recorded in the local area recording means 3, the time is also recorded, and when there are a plurality of mobile units for call control, the time can be obtained from the time. Sequential call control is applied based on the location time,
You may make it connect with the mobile device which responded.

(5) When the sequential call control of (4) above is performed, the mobile unit record table is updated so that the selection priority is lowered when the call with each mobile unit is completed, and the calling order is changed. You may make it equalize.

(6) As shown in FIG. 2, the calling subscriber dials the subscriber group number from the fixed telephone TEL following the dialed numbers shown in FIG. 4, and performs the fixed network telephone exchange in the same manner as in the known connection control. When connected to the mobile switching center MSC via the TEL switching center EX, the mobile telephone switching center MSC receives the dialed number as the subscriber group number and the area code including the area code and the local code. (c) The local area mobile unit record table is indexed and searched to find the subscriber number located in the designated area, and by controlling the call using this number, the fixed telephone and the designated area mobile unit can be connected to each other. ..
