Abstract

A subscriber data control method in a mobile communication network which reduces the processing load on a mobile switching center and can effectively use the resource of a visitor subscriber data area is provided the subscriber data of the visitor mobile station is not deleted in response to the subscriber data delete request from its home mobile switching center due to a fact that the visitor mobile station has further moved to another service area, and the state of the registered subscriber data of the visitor mobile station is set as the inactive holding state from the active state, and thereafter in the case where the visitor mobile station returns to the subject service area within a predetermined period of time and again performs the location registration, restoration of the subscriber data of the visitor mobile station can be made by only changing the state of the subscriber data from the inactive state to the active state. With respect to the subscriber data being put as the inactive holding state, it is deleted if no location registration is made within a predetermined period of time.

Claims

1-10. -10. (canceled)

11. A subscriber data control method for a mobile communication system, comprising:

receiving at a destination mobile switching center a request for location registration from a mobile station;

transmitting from said destination mobile switching center to a home mobile switching center a subscriber data request signal for said location registration;

judging at said home mobile switching center whether or not said home mobile switching center transmits a subscriber data to said destination mobile switching center by an indication in said subscriber data request signal; and

not transmitting said subscriber data from said home mobile switching center to said destination mobile switching center if said home mobile switching center judges not transmitting said subscriber data.

12. The subscriber data control method as claimed in claim 11, wherein said indication in said subscriber data request signal means that the transfer of said subscriber data from said home mobile switching center to said destination mobile switching center is not necessary if said destination mobile switching center is keeping said subscriber data.

13. The subscriber data control method as claimed in claim 12 further comprising, keeping said subscriber data at said destination mobile switching center within at least a predetermined time period.

14. The subscriber data control method as claimed in claim 13, wherein said predetermined time period is counted from a last periodic location registration operation by said mobile station to said destination mobile switching center.

15. A mobile communication system comprising:

a destination mobile switching center which receives a request for location registration from a mobile station and transmits a subscriber data request signal for said location registration; and

a home mobile switching center which judges whether or not said home mobile switching center transmits a subscriber data to said destination mobile switching center by an indication in said subscriber data request signal and does not transmits said subscriber data if said home mobile switching center judges not transmitting said subscriber data.

16. The mobile communication system as claimed in claim 15, wherein said indication in said subscriber data request signal means that the transfer of said subscriber data from said home mobile switching center to said destination mobile switching center is not necessary if said destination mobile switching center is keeping said subscriber data.

17. The mobile communication system as claimed in claim 16, wherein said destination mobile switching center is keeping said subscriber data within at least a predetermined time period.

18. The mobile communication system as claimed in claim 17, wherein said predetermined time period is counted from a last periodic location registration operation by said mobile station to said destination mobile switching center.

19. A mobile communication system comprising:

means for receiving at a destination mobile switching center a request for location registration from a mobile station;

means for transmitting from said destination mobile switching center a subscriber data request signal for said location registration; and

means for judging at said home mobile switching renter whether or not said home mobile switching center transmits a subscriber data to said destination mobile switching center by an indication in said subscriber data request signal,

wherein said home mobile switching center does not transmits said subscriber data if said home mobile switching center judges not transmitting said subscriber data.

20. The mobile communication system as claimed in claim 19, wherein said destination mobile switching center is keeping said subscriber data within at least a predetermined time period.

21. A subscriber data control method for a mobile communication system, comprising:

receiving at a destination mobile switching center a location registration request from a mobile station;

first transmitting from said destination mobile switching center to a home mobile switching center a request signal for a new subscriber data in response to said location registration request; and

second transmitting from said home mobile switching center to a previous mobile switching center a subscriber data delete request signal for deleting an old subscriber data stored in said previous mobile switching center in response to said request signal for a new subscriber data,

wherein said home mobile switching center does not transmit said subscriber data delete request signal if said previous mobile switching center is organized for contributing to an effective use of a resource in said mobile communication system.

22. The subscriber data control method as claimed in claim 21, wherein said home mobile switching center does not transmit said subscriber data delete request signal if said previous mobile switching center is organized for deletion said old subscriber data automatically without said subscriber data delete request signal.

23. The subscriber data control method as claimed in claim 21, wherein said home mobile switching center does not transmit said subscriber data delete request signal if said previous mobile switching center is organized for deletion said old subscriber data automatically after elapse of at least a predetermined time period.

24. The subscriber data control method as claimed in claim 23, wherein said predetermined time period is counted from the last periodic location registration operation by said mobile station to said destination mobile switching center.

25. A mobile communication system comprising:

a destination mobile switching center which receives a location registration request from a mobile station and transmits a request signal for a new subscriber data in response to said location registration; and

a home mobile switching center transmits a subscriber data delete request signal to a previous mobile switching center for deleting an old subscriber data stored in said previous mobile switching center in response to said request signal for a new subscriber data,

wherein said home mobile switching center is organized for contributing to an effective use of a resource in said mobile communication system.

26. The mobile communication system as claimed in claim 25, wherein said home mobile switching center does not transmit said subscriber data delete request signal if said previous mobile switching center is organized for deletion said old subscriber data automatically without said subscriber data delete request signal.

27. The mobile communication system as claimed in claim 26, wherein said home mobile switching center does not transmit said subscriber data delete request signal if said previous mobile switching center is organized for deletion said old subscriber data automatically after elapse of at least a predetermined time period.

28. The mobile communication system as claimed in claim 27, wherein said predetermined time period is counted from a last periodic location registration operation by said mobile station to said destination mobile switching center.

29. A mobile communication system comprising:

means for receiving at a destination mobile switching center a location registration request from a mobile station;

means for first transmitting from said destination mobile switching center to a home mobile switching center a request signal for a new subscriber data in response to said location registration request; and

means for second transmitting from said home mobile switching center to a previous mobile switching center a subscriber data delete request signal for deleting an old subscriber data stored in said previous mobile switching center in response to said request signal for a new subscriber data,

wherein said mean for second transmitting is not executed if said previous mobile switching center is organized for contributing to an effective use of a resource in said mobile communication system.
