finding another subscriber having subscriber data thereof stored in the high-priority-subscriber-storage area if there is no space in the high-priority-subscriber-storage area, said another subscriber having lower priority than the relevant subscriber and being not currently on phone; and
creating a space in the high-priority-subscriber-storage area for storing the subscriber data of the relevant subscriber if there is no space in the high-priority-subscriber-storage area by moving the subscriber data of said another subscriber from the high-priority-subscriber-storage area to the ordinary-subscriber-storage area.

5. The method as claimed in claim 1, wherein said step c) further includes the steps of:
-
finding another subscriber having subscriber data thereof stored in the high-priority-subscriber-storage area if there is no space in the high-priority-subscriber-storage area, said another subscriber having a lowest priority lower than that of the relevant subscriber and being not currently on phone; and
creating a space in the high-priority-subscriber-storage area for storing the subscriber data of the relevant subscriber if there is no space in the high-priority-subscriber-storage area by moving the subscriber data of said another subscriber from the high-priority-subscriber-storage area to the ordinary-subscriber-storage area.

6. A method of deleting subscriber data of a mobile station in a mobile-communication system, comprising the steps of:
-
a) checking priority of a mobile station when receiving a message indicating either a power down of the mobile station or a completion of a call by the mobile station to determine whether the mobile station belongs to a service class having a high priority, which exceeds a predetermined threshold;
b) keeping subscriber data of the mobile station if the mobile station belongs to the service class having the high priority; and
c) deleting the subscriber data of the mobile station if the mobile station does not belong to the service class having high priority, wherein subscribers are treated in different manners depending on the service class thereof. - View Dependent Claims (7, 8)
setting a time period in accordance with the priority of the mobile station; and
deleting the subscriber data of the mobile station at an end of said time period after receiving the message if the priority of the mobile station does not exceed the predetermined threshold.

-
8. The method as claimed in claim 7, wherein said step of setting a time period includes a step of setting a time period that is longer as the priority of the mobile station becomes greater.

9. A method of storing subscriber data in a mobile-communication system, comprising the steps of:
-
a) checking priority of a relevant subscriber to determine whether the relevant subscriber belongs to a service class having a high priority, which exceeds a predetermined threshold;
b) storing subscriber data of the relevant subscriber in a data-storage area if there is a space therein; and
c) replacing subscriber data of another subscriber in the data-storage area with the subscriber data of the relevant subscriber in an event that the data-storage area is full and the relevant subscriber belongs to the service class having high priority, said another subscriber belongs to a service class having lower priority than the relevant subscriber and being currently not on phone. - View Dependent Claims (10)

11. A device for controlling storage of subscriber data in a high-priority-subscriber-storage area and an ordinary-subscriber-storage area, comprising:
-
a priority-check unit which checks priority of a relevant subscriber to determine whether the relevant subscriber belongs to a service class having a high priority, which exceeds a predetermined threshold; and
a data-storage-control unit which stores subscriber data of the relevant subscriber in the high-priority-subscriber-storage area only if the relevant subscriber belongs to the service class having high priority in an event that the ordinary-subscriber-storage area is full, thereby treating subscribers in different manners depending on the service class thereof. - View Dependent Claims (12, 13, 14, 15)

16. A device for deleting subscriber data of a mobile station in a mobile-communication system, comprising:
-
a message receiving unit which receives a message indicating either a power down of a mobile station or a completion of a call by the mobile station;
a priority-check unit which checks priority of the mobile station, when the message receiving unit receives the message, to determine whether the mobile station belongs to a service class having a high priority, which exceeds a predetermined threshold; and
a data-storage-control unit which keeps subscriber data of the mobile station if the mobile station belongs to the service class having high priority, and deletes the subscriber data of the mobile station if the mobile station does not belong to the service class having high priority, thereby treating mobile stations in different manners depending on the service class thereof. - View Dependent Claims (17, 18)

19. A device of storing subscriber data in a data-storage area of a mobile-communication system, comprising:
-
a priority-check unit which checks priority of a relevant subscriber to determine whether the relevant subscriber belongs to a service class having a high priority, which exceeds a predetermined threshold;
a data-search unit which finds another subscriber having subscriber data thereof stored in the data-storage area who belongs to a service class having a lower priority than the relevant subscriber and being currently not on phone; and
a data-storage-control unit which stores subscriber data of the relevant subscriber in the data-storage area if there is a space therein, and replacing the subscriber data of said another subscriber in the data-storage area with the subscriber data of the relevant subscriber in an event that the data-storage area is full and the relevant subscriber belongs to the service class having a high priority. - View Dependent Claims (20)
