Abstract

A method for controlling an idle mode in a mobile station comprises transmitting an idle mode request to a serving base station to enter the idle mode, and receiving a decode information transmission frame value and a decode information change status from at least one base station. The method also comprises, if the decode information change status indicates a change in the decode information, maintaining the idle mode, and receiving the decode information from the at least one base station when the transmission frame value is reached. The decode information may comprise at least one of downlink channel descriptor (DCD) information, uplink channel descriptor (UCD) information, and forward error correction (FEC) code type information. The transmission frame value may comprise a frame number or a frame offset. The at least one base station may be in a same paging group.

Claims

1. A method for controlling an idle mode in a mobile station, the method comprising:

transmitting an idle mode request to a serving base station to enter the idle mode;

receiving a decode information transmission frame value and a decode information change status from at least one base station; and

if the decode information change status indicates a change in the decode information;

maintaining the idle mode; and

receiving the decode information from the at least one base station when the transmission frame value is reached.

2. The method of claim 1, wherein the decode information comprises at least one of downlink channel descriptor (DCD) information and uplink channel descriptor (UCD) information.

3. The method of claim 1, wherein the decode information comprises forward error correction (FEC) code type information.

4. The method of claim 1, wherein the transmission frame value comprises a frame number.

5. The method of claim 1, wherein the transmission frame value comprises a frame offset.

6. The method of claim 1, wherein the at least one base station is in a same paging group.

7. The method of claim 1, further comprising:

maintaining the idle mode if the decode information change status indicates no change in the decode information.

8. A method in a network for controlling an idle mode in a mobile station, the method comprising:

receiving an idle mode request from a mobile station to enter the idle mode;

transmitting a decode information transmission frame value and a decode information change status to the mobile station;

wherein,

if the decode information change status indicates a change in the decode information, the mobile station maintains the idle mode; and

transmitting the decode information to the mobile station when the transmission frame value is reached.

9. The method of claim 8, wherein the network comprises at least one base station and a paging controller, the paging controller configured to control paging within base stations of a paging group.

10. The method of claim 8, wherein the decode information comprises at least one of downlink channel descriptor (DCD) information and uplink channel descriptor (UCD) information.

11. The method of claim 8, wherein the decode information comprises forward error correction (FEC) code type information.

12. The method of claim 8, wherein the decode information transmission frame value and the decode information change status are broadcast to the mobile station at each paging interval.

13. A mobile station for controlling an idle mode in a wireless access system, the mobile station comprising:

means for transmitting an idle mode request to a serving base station to enter the idle mode;

means for receiving a decode information transmission frame value and a decode information change status from at least one base station; and

if the decode information change status indicates a change in the decode information;

means for maintaining the idle mode; and

means for receiving the decode information from the at least one base station when the transmission frame value is reached.

14. The mobile station of claim 13, wherein the decode information comprises at least one of downlink channel descriptor (DCD) information and uplink channel descriptor (UCD) information.

15. The mobile station of claim 13, wherein the decode information comprises forward error correction (FEC) code type information.

16. The mobile station of claim 13, wherein the transmission frame value comprises a frame number.

17. The mobile station of claim 13, wherein the transmission frame value comprises a frame offset.

18. The mobile station of claim 13, wherein the at least one base station is in a same paging group.

19. The mobile station of claim 13, further comprising:

means for maintaining the idle mode if the decode information change status indicates no change in the decode information.

20. A network for controlling an idle mode in a mobile station, the network comprising:

means for receiving an idle mode request from a mobile station to enter the idle mode;

means for transmitting a decode information transmission frame value and a decode information change status to the mobile station;

wherein,

if the decode information change status indicates a change in the decode information, the mobile station maintains the idle mode; and

means for transmitting the decode information to the mobile station when the transmission frame value is reached.

21. The network of claim 20, wherein the network comprises at least one base station and a paging controller, the paging controller configured to control paging within base stations of a paging group.

22. The network of claim 20, wherein the decode information comprises at least one of downlink channel descriptor (DCD) information and uplink channel descriptor (UCD) information.

23. The network of claim 20, wherein the decode information comprises forward error correction (FEC) code type information.

24. The network of claim 20, wherein the decode information transmission frame value and the decode information change status are broadcast to the mobile station at each paging interval.
