[Operation of additional registration of regional code in wireless communication system]
Next, in the wireless communication system according to the embodiment of the present invention, the operation when the area code is additionally registered in the mobile station (A) 106 will be described with reference to FIG. FIG. 6 is a diagram showing an operation sequence when an area code is additionally registered in a mobile station in the wireless communication system according to the embodiment of the present invention.
For example, the operator of the wireless communication system in the area (A) sends the mobile station (A) 106 belonging to the area (A) to the area (B) to support the work in response to the disaster that occurs in the area (B). At the time of dispatching, the operation instruction unit 42 of the control table (A) 104 is operated, the mobile station (A) 106 to be dispatched is designated, and an additional registration request for the area code is input (step S101).
The control unit 41 of the control table (A) 104 transmits a region code additional registration request to the control server (A) 103 (step S102).
When the control unit 31 of the control server (A) 103 receives the area code additional registration request (step S103), the designated mobile station and the additional area code are received from the area code additional registration request transmitted from the control table (A) 104. And information such as the additional area code usable period is acquired and registered in the area code management table 32a of the storage unit 32 (step S104). For example, as shown in FIG. 3, for mobile stations (A) 106-1 and 106-2, "B0001" is used for the additional area code 32ad, and "2016/10/01" is used for the additional area code usable period 32af. ~ 2016/12/31 "is registered.

On the other hand, when the mobile station (A) 106 belonging to the area (A) is turned on (step S111) and enters the service area by capturing an arbitrary base station (A) 102 (step S112), The control station (A) 101 is notified of the service area information by wireless communication via the base station (A) 102 (step S113). The control station (A) 101 gives an instruction to register the service area information to the control server (A) based on the service area information transmitted from the mobile station (A) 106 (step S114).

The control server (A) 103 registers the service area information of the mobile station (A) 106 in a predetermined area of the storage unit 32 (step S115).
Further, the control server (A) 103 confirms whether or not there is a request for additional registration of the area code for the mobile station whose service area information is registered in the area code management table 32a (step S116). When the request for additional registration of the area code to the mobile station (A) 106 in which the service area information is registered is registered (step S116: Yes), the control server (A) 103 informs the control station (A) 101. The area code additional data is transmitted to the mobile station (step S117). The control station (A) 101, which has received the area code additional data from the control server (A) 103, uses the area code by wireless communication via the corresponding base station (A) 102 based on the registered service area information. The additional data is transmitted to the mobile station (A) 106 (step S118).

When the mobile station (A) 106 receives the area code additional data from the control station (A) 101, the area code addition / deletion means 61a of the control unit 61a receives the additional area code and the additional area from the received area code additional data. The information of the code usable period is registered in the area code individual information table 61ba of the storage unit 61b (step S119). For example, as shown in FIG. 5, in the case of mobile station (A) 106-1, "B0001" is set for the additional area code 61bad, and "2016/10/01 to 2016/12" is set for the additional area code usable period 61bae. / 31 "is registered.
When the area code additional registration is completed, the control unit 61 of the mobile station (A) 106 currently communicating sends a notification of the completion of the area code additional registration by wireless communication via the base station (A) 102 to the control station (A) 101. (Step S120).

When the control unit 12 of the control station (A) 101 receives the notification of the completion of registration of the additional area code from the mobile station (A) 106, the control unit 12 of the control station (A) 101 tells the control server (A) 103 the area code of the corresponding mobile station (A) 106. An instruction is given to complete the additional registration request (step S121).
When the control server (A) 103 receives an instruction from the control station (A) 101 to complete the area code addition registration request to the mobile station (A) 106 (step S122), the area code addition implementation status of the area code management table 32a Set a completion flag indicating that the process has been completed (step S123) (see FIG. 3). If the control server (A) 103 has not registered the area code addition registration request to the mobile station (A) 106 that has registered the service area information (step S116: none), the control server (A) 103 has registered the service area information. No processing is performed.

Further, in the mobile station (A) 106, the area code addition / deletion means 61a of the control unit 61a periodically confirms the additional area code usable period 61bae registered in the area code individual information table 61ba of the storage unit 61b. , The added area code will be automatically deleted when the usable period has expired. When the mobile station (A) 106 has a means for acquiring the time information, the acquired time information may be compared with the additional area code usable period 61bae to determine whether or not to delete the time information.

In the above embodiment, the mobile station (A) 106 itself deletes the area code additionally registered in the mobile station (A) 106, but the operation sequence of the area code additional registration shown in FIG. 6 is used. Similarly, the system operator may perform the operation instruction from the control table (A) 104.

As described above, according to the wireless communication system according to the embodiment of the present invention, the number of area codes that can be held by the mobile station is increased, and the area code information required for the control station is registered in advance. , By adding a function to automatically add a regional code by remote control by wireless communication, it is possible to improve the convenience of system users.
The control station may store the individual number of the mobile station and the additional area code in association with each other, and transmit the additional area code to the mobile station to which the individual number is assigned. .. This makes it possible to register additional area codes only for necessary mobile stations.
In addition, the control station stores the individual number of the mobile station, the additional area code, and the usable period of the additional area code in association with each other, and for the mobile station to which the individual number is assigned, the additional area. The mobile station that transmitted the code and the usable period and received the area code and the usable period stores the received additional area code and the usable period and uses it. After the possible period, the stored additional area code may be deleted. This makes it possible to automatically delete the area code when the support period has expired.
In addition, when registering the service area information of the mobile station, the control station confirms whether the additional area code associated with the individual number of the mobile station is stored, and the additional area code is stored. In that case, the additional area code may be transmitted to the mobile station. This makes it possible to reliably transmit the additional area code to the mobile station.
