First transfer means for transferring to the storage means of the base station corresponding to the zone, location registration area number transferred from another base station at the time of termination of the mobile station call, and location registration area number stored in the storage means One with Or, determine the disagreement, when determining the disagreement of the two location registration area numbers, comprising a second transmission means for transmitting a new location registration area number to the mobile station and the exchange, the mobile station and The exchange has an updating unit that updates the contents of the storage unit of the local station with the new location registration area number transmitted from the second transmission unit.

[0006]

The location registration area where the mobile station is present is stored in the base station at the time of call connection, and the stored location registration area is transmitted to the switching destination base station at the time of zone switching. When the location registration area at the time of the call connection and the location registration area of the own station are different, the mobile station is notified of the information of the location registration area of the own station to the mobile station,
Request the exchange to update the location of the mobile station.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of this embodiment. In this embodiment, as shown in FIG. 1, a plurality of base stations 11 corresponding to one of the wireless zones having a location registration area number, and a mobile station 2 performing wireless communication with one of the base stations 11 And a switching station 13 accommodating a plurality of base stations 11 and connected to a fixed network 14,
Each of the mobile station 12, the base station 11, and the switching station 13 includes storage means for storing a location registration area number, and as a feature of the present invention, the base station 11
When the mobile station 12 in the wireless zone corresponding to the own base station moves from the wireless zone, the location registration area number stored in the storage means of the own base station is stored in the base station corresponding to the destination wireless zone. The first transfer means for transferring to the means, and at the end of the call of the mobile station 12, determine whether the location registration area number transferred from the other base station matches the location registration area number stored in the storage means. And a second transmitting means for transmitting a new location registration area number to the mobile station 12 and the exchange 13 when it is determined that the two location registration area numbers do not match. Comprises updating means for updating the contents of the storage means of the own station to the new location registration area number transmitted from the second transmitting means.

Next, the operation of this embodiment will be described. FIG.
Is a flow chart of this embodiment, the mobile station call,
This shows a case where a zone change during a call and a mobile station end call are performed. When a calling operation is performed in the mobile station (step 10)
1), a call signal 1 is transmitted to the base station A and the exchange,
The base station A that has received the call signal 1 stores the location registration area number of the own station (step 201), the exchange station makes a connection (step 401), and transmits a connection completion signal 2 to the base station A and the mobile station. However, the switching station, the base station A and the mobile station are busy on the call (steps 102, 2
02, 402). When the mobile station detects that the mobile station has moved from one zone to another during a call (step 103), the mobile station transmits the switching request signal 3 to the base station A, and the base station A stores the switching request signal 3 in step 201. A location registration area number is assigned (step 203), and the switching signal 4 is transmitted to the switching center and the base station B as the switching destination. The base station B that has received the switching signal 4 stores the location registration area number of the switching signal 4 (step 301), and the exchange performs the switching operation (step 40).
3) The switch completion signal 4 is transmitted to the mobile station, the base station A and the base station B.

When the mobile station ends the call (step 10)
4), the call termination request signal 6 is transmitted to the base station B, and upon receiving the signal, the base station B compares the location registration area number stored in step 301 with its own location registration area number (step 302). If not, the base station B looks at its own zone information (step 303) and transmits a call termination zone information notification signal 7 to the mobile station and a call termination position update request signal 8 to the exchange. The mobile station that has received the end-of-call zone information notification signal 7 stores new zone information (step 10).
5) The mobile station that has received the call end position update request signal 8 updates the location information of the mobile station (step 404). If they match in step 302, the call completion signal 8 is transmitted to the mobile station and the call termination signal 9 is transmitted to the exchange. In this way, the mobile station, the base station B, and the exchange end the call (steps 106, 304, 405).

[0010]

As described above, according to the present invention, at the end of a call, the mobile station can obtain information on a new zone, so that the next call can be started immediately after the end of a call.
