[0003] In order to enhance the convenience so that the user does not need to consider the zone, a system called roaming is adopted. This is a technology that enables a mobile phone to be used via a service of another company even when the user goes out of the service area of a specific company. In order to realize such roaming, it is necessary to keep the mobile terminal exchanges of the roaming companies in a connected state, and the cost cannot be reduced at present.

On the other hand, a digital cordless telephone system (hereinafter abbreviated as “DCT”) represented by a PHS is flexible in that it can be connected to any system as long as a certain standard is satisfied. It has. This flexibility is manifested, in particular, in that it can be used as a cordless telephone at home, and can be used like a mobile phone when taken outside.

It is basically composed of a CT 1, a plurality of base stations 2, and a mobile terminal exchange 3. FIG. 1 is a configuration block diagram showing a DCT system.

Hereinafter, each part will be described in detail.
1 has already been described, and the description is omitted.
The base station 2 mediates between the DCT 1 and the mobile terminal exchange 3, and receives a signal from the nearby DCT 1 and outputs the signal to the mobile terminal exchange 3, and also receives a signal input from the mobile terminal exchange. This is to transmit and output to DCT1.

Incidentally, the base station 2 has a narrow range (cell) in which radio transmission / reception is possible, and a plurality of base stations 2 are usually installed in one zone.

[0008] The portable terminal exchange 3 is to exchange D
The CT 1 stores which base station 2 is currently in the cell covered by the mobile station as mobile terminal information. Therefore, even if the DCT 1 in which the mobile terminal information is not stored is in the zone, the mobile terminal exchange 3 cannot process the signal to be transmitted from now on, so that the DCT 1 cannot be used.

For this reason, taking advantage of the above flexibility, a zone is set at a specific event venue so that the DCT can be used within the venue, or a zone can be set within the company and the DCT can be set up in the company. The use of DCT has been considered, such as using a DCT inside the island by setting a zone on a remote island. Until this mobile terminal information is stored, the DCT cannot be used.
