Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of simultaneously calling mobile terminals belonging to an arbitrary group in a communication network which enables the operation of mobile terminals.

[0002]

2. Description of the Related Art Recently, with the development of communication technology, in addition to desk-top type telephone terminals, mobile type portable telephone terminals, mobile type call-only terminals, etc. have become widespread.

Here, FIG. 8 shows a schematic configuration of a communication network that enables the operation of mobile terminals. In the figure, the communication network is
Area A, area B, and area C are divided into three areas. Area A has a repeater A, area B has a repeater B, and area C has a repeater C, respectively.
Exchange A, exchange B, and exchange C are arranged.

Each exchange has a home database HM (A) for storing an area identifier for identifying a destination area (currently located area) together with a called number of a mobile terminal,
Home database HM (B), home database H
Connect M (C).

In the home database HM (A), a terminal 000 registered with area A as a base area at the time of joining
1. Store the incoming call number of the terminal 0002 and the current position information. The home database HM (B) stores the terminal 0011, the incoming call number of the terminal 0012, and the current position information registered at the time of joining as the base area.

[0006] In the home database HM (C), the terminal 011 registered with the area C as a base area at the time of joining.
1. Store the incoming call number and the current position information of the terminal 0112. An area identifier that identifies the area where the mobile terminal is located is stored as the current location information.

When an arbitrary mobile terminal enters the area managed by itself, the repeater in each area recognizes the called number of this mobile terminal and transmits the called number and the area identifier of its own area to the exchange. To do. The exchange accesses the home database HM based on the called number,
The current location information of the mobile terminal is rewritten to the area identifier received from the repeater. Specifically, when the terminal 0112 enters the area A, the relay machine A determines whether the terminal 0
The incoming call number "0112" of 112 is recognized, and the incoming call number "0112" and the area identifier "A" are transmitted to the exchange C.

The exchange C accesses the home database HM (C) based on the incoming number "0112" and writes the area A in the current position information storage area of the terminal 0112. As a result, when the call request to the terminal 0112 is received, the exchange C recognizes the called number "0112" of the called terminal (terminal 0112) from the call request, and performs home based on the called number. Access the database HM (C). Then, the current position information “Area A” of the terminal 0112 is recognized from the home database HM (C),
The incoming call notification is transmitted to the repeater A arranged in the area A together with the incoming call number "0112" of the terminal 0112. The repeater C determines the terminal 0112 based on the incoming number “0112”.
The incoming call notification can be transmitted to.

[0009]

By the way, in the above-mentioned communication network, when a group is composed of a plurality of mobile terminals whose base areas are different areas, and when a paging request for this group is received, the exchange will make the group concerned. It is necessary to read out the current position information of each mobile terminal belonging to the above from multiple home databases. Therefore, there is a problem that the call arrival notification is delayed at each terminal.

Therefore, an object of the present invention is to use a means for collectively managing the position information of the mobile terminals in a group together with the above home database to improve the efficiency of the processing related to the group paging.

[0011]

The present invention has the following features to attain the object mentioned above. This will be described based on the principle diagram of FIG.

The call processing means 1c is intended to notify the mobile terminals registered in the group management table 1b of the incoming call all at once. Further, each exchange 1 may be provided with a management unit 1d that updates the destination area identifier of the home database 1a and the group management table 1b when the mobile terminal 2 moves between arbitrary areas.

Further, in the home database 1a and the group management table 1b, communication state identification information for identifying whether or not each mobile terminal 2 is in a callable state may be registered.

[0017]

In the exchange 1, when the call request to the arbitrary mobile terminal 2 is recognized, the call processing means 1c recognizes the called number of the mobile terminal 2 and accesses the home database 1a. In the home database 1a, first, the representative mobile terminal identification information of the mobile terminal 2 is referenced to determine whether or not the mobile terminal 2 is the representative mobile terminal.

When the mobile terminal 2 is the representative mobile terminal, the group identifier is read from the home database 1a. The group management table 1b is accessed based on this group identifier, and the called numbers and destination area identifiers of all the mobile terminals 2 belonging to the group are read out.

Further, the incoming call number of the mobile terminal 2 and the incoming call notification are transmitted to the relay station 3 in the destination area where each mobile terminal 2 is located. As a result, the relay station 3 in each destination area
Can send a call incoming notification to each mobile terminal 2 based on the called number received from the exchange 1.

If the mobile terminal 2 that has received the call request is not the representative mobile terminal, the destination area identifier of the mobile terminal 2 is read from the home database 1a and the destination mobile station 2 moves to the relay station 3 in the destination area. The incoming call number of the terminal 2 and the incoming call notification are transmitted.

Next, the process of updating the destination area will be described. When an arbitrary mobile terminal 2 moves within its own area, the relay station 3 recognizes the incoming number of the mobile terminal 2 and sends the incoming number to the exchange 1 that manages the area where the mobile terminal 2 is based. And the area identifier of its own area.

In the exchange 1, the incoming call number and the area identifier transmitted from the relay station 3 are notified to the managing means 1d, and the managing means 1d accesses the home database 1a based on the incoming call number. Then, the destination area identifier of the mobile terminal 2 is rewritten to the area identifier received from the relay station 3. Further, the group management table 1b is accessed based on the group identifier of the group to which the mobile terminal 2 belongs, and the destination area identifier of the mobile terminal 2 is rewritten to the area identifier received from the relay station 3.
