Abstract

The present invention is to provide the mobile communication system which enables power consumption reduction for the mobile station with dual mode capability by unifying the location registration and paging processing for every mobile communication system. The mobile communication system is so arranged to perform location registration processing and paging processing for the mobile station by only one of radio communication systems. And the mobile station can access to any other radio communication systems.

Claims

1. A mobile station for a mobile communication system comprising a first communication system which comprises a first network node and a second communication system which comprises a second network node, the mobile station comprising:

a receiver adapted to receive a paging message from a base station connected to the first network node which receives a request message from the second network node, wherein the second network node receives a voice call and responds to receipt of the voice call by sending the request message to the first network node; and

a transmitter adapted to transmit, to the second network node, a message which responds to the paging message, when the mobile station has performed location registration to only the first communication system from among the first communication system and the second communication system, wherein the mobile station establishes a connection with the second network node,

wherein a first radio technology of the first communication system is different from a second radio technology of the second communication system.

2. The mobile station according to claim 1, wherein the second radio technology of the second communication system is wideband code division multiple access (W-CDMA).

3. The mobile station according to claim 1, wherein the second communication system further comprises a subscriber information storage,

wherein the subscriber information storage stores information related to the first network node.

4. The mobile station according to claim 3, wherein the information related to the first network node indicates an association with the first network node.

5. The mobile station according to claim 1, wherein the mobile station transmits, to the first communication system, an unified request for the location registration to only the first communication system from among the first communication system and the second communication system.

6. The mobile station according to claim 1, wherein the paging message is transmitted after the location registration has been performed.

7. A mobile station for a mobile communication system comprising a first communication system which comprises a first network node and a second communication system which comprises a second network node, the mobile station comprising:

a receiver adapted to receive a paging message from a base station connected to the first network node which receives a request message from the second network node, wherein the second network node receives a voice call and responds to receipt of the voice call by sending the request message to the first network node; and

a transmitter adapted to transmit, to the second network node, a message which responds to the paging message, when the mobile station has performed location registration to the first communication system and has not performed location registration to the second communication system, wherein the mobile station establishes a connection with the second network node,

wherein a first radio technology of the first communication system is different from a second radio technology of the second communication system.

8. The mobile station according to claim 7, wherein the second radio technology of the second communication system is wideband code division multiple access (W-CDMA).

9. The mobile station according to claim 7, wherein the second communication system further comprises a subscriber information storage,

wherein the subscriber information storage stores information related to the first network node.

10. The mobile station according to claim 9, wherein the information related to the first network node indicates an association with the first network node.

11. The mobile station according to claim 7, wherein the mobile station transmits, to the first communication system, an unified request for the location registration to only the first communication system from among the first communication system and the second communication system.

12. The mobile station according to claim 7, wherein the paging message is transmitted after the location registration has been performed.

13. A method for a mobile station in a mobile communication system comprising a first communication system which comprises a first network node and a second communication system which comprises a second network node, the method comprising:

receiving a paging message from a base station connected to the first network node which receives a request message from the second network node, wherein the second network node receives a voice call and responds to receipt of the voice call by sending the request message to the first network node; and

transmitting, to the second network node, a message which responds to the paging message, when the mobile station has performed location registration to only the first communication system from among the first communication system and the second communication system, wherein the mobile station establishes a connection with the second network node,

wherein a first radio technology of the first communication system is different from a second radio technology of the second communication system.

14. The method according to claim 13, wherein the second radio technology of the second communication system is wideband code division multiple access (W-CDMA).

15. The method according to claim 13, wherein the second communication system further comprises a subscriber information storage,

wherein the subscriber information storage stores information related to the first network node.

16. The method according to claim 15, wherein the information related to the first network node indicates an association with the first network node.

17. The method according to claim 13, wherein the mobile station transmits, to the first communication system, an unified request for the location registration to only the first communication system from among the first communication system and the second communication system.

18. The method according to claim 13, wherein the paging message is transmitted after the location registration has been performed.

19. A method for a mobile station in a mobile communication system comprising a first communication system which comprises a first network node and a second communication system which comprises a second network node, the method comprising:

receiving a paging message from a base station connected to the first network node which receives a request message from the second network node, wherein the second network node receives a voice call and responds to receipt of the voice call by sending the request message to the first network node; and

transmitting, to the second network node, a message which responds to the paging message, when the mobile station has performed location registration to the first communication system and has not performed location registration to the second communication system, wherein the mobile station establishes a connection with the second network node,

wherein a first radio technology of the first communication system is different from a second radio technology of the second communication system.

20. The method according to claim 19, wherein the second radio technology of the second communication system is wideband code division multiple access (W-CDMA).

21. The method according to claim 19, wherein the second communication system further comprises a subscriber information storage,

wherein the subscriber information storage stores information related to the first network node.

22. The method according to claim 21, wherein the information related to the first network node indicates an association with the first network node.

23. The method according to claim 19, wherein the mobile station transmits, to the first communication system, an unified request for the location registration to only the first communication system from among the first communication system and the second communication system.

24. The method according to claim 19, wherein the paging message is transmitted after the location registration has been performed.
