Abstract

A method of establishing a channel in a wireless communication system is disclosed. The method of establishing a dedicated channel of a user equipment in a wireless communication system includes, receiving channel configuration information which is required for establishing the dedicated channel from a network, transmitting a first status report to the network if at least one first condition is satisfied, and establishing the dedicated channel using the channel configuration information after transmitting the first status report. As a result, the wireless communication system can increase its scheduling efficiency using buffer status information of the UE.

Claims

1. A method of establishing a dedicated channel of a user equipment (UE) in a wireless communication system comprising:

receiving channel configuration information which is required for establishing the dedicated channel from a network;

transmitting a first status report to the network if at least one first condition is satisfied; and

establishing the dedicated channel using the channel configuration information after transmitting the first status report.

2. The method according to claim 1, further comprising:

transmitting a second status report to the network if at least one second condition is satisfied; and

releasing the dedicated channel after transmitting the second status report.

3. The method according to claim 1, wherein the dedicated channel is periodically allocated.

4. The method according to claim 2, wherein the at least one first condition and the at least one second condition are received from the network.

5. The method according to claim 1, further comprising:

performing a scheduling request via the dedicated channel; and

receiving scheduling allocation information from the network.

6. The method according to claim 2, wherein the at least one first condition is satisfied when an amount of data stored in a buffer of the user equipment (UE) is less than a first threshold value.

7. The method according to claim 2, wherein the at least one second condition is satisfied when an amount of data stored in a buffer of the user equipment (UE) is greater than a second threshold value.

8. The method according to claim 6, wherein the first status report and the second status report include buffer status information of the user equipment (UE).

9. The method according to claim 1, wherein the at least one first condition is satisfied when a talk or communication period is shifted to a silence period in a voice communication.

10. The method according to claim 9, wherein the at least one second condition is satisfied when the silence period is shifted to the talk or communication period in the voice communication.

11. The method according to claim 9, wherein the first status report and the second status report include information associated with a mode shift.

12. The method according to claim 9, wherein the first status report and the second status report are transmitted to the network according to a hybrid automatic repeat request (HARQ) scheme.

13. A method of controlling configuration of a dedicated channel of a user equipment (UE) in a network of a wireless communication system comprising:

transmitting channel configuration information which is required for establishing the dedicated channel to a user equipment (UE);

receiving a first status report indicating that at least one first condition is satisfied from the user equipment (UE); and

receiving a message transmitted via the established dedicated channel, which is established using the channel configuration information.

14. The method according to claim 13, further comprising:

receiving a second status report from the user equipment (UE) if at least one second condition is satisfied; and

releasing the dedicated channel after receiving the second status report.

15. The method according to claim 13, wherein the dedicated channel is periodically allocated.

16. The method according to claim 13, further comprising:

receiving a scheduling request via the dedicated channel from the user equipment (UE); and

transmitting scheduling allocation information to the user equipment (UE).

17. The method according to claim 14, wherein the at least one first condition is satisfied when an amount of data stored in a buffer of the user equipment (UE) is less than a first threshold value.

18. The method according to claim 14, wherein the at least one second condition is satisfied when an amount of data stored in a buffer of the user equipment (UE) is greater than a second threshold value.

19. The method according to claim 17, wherein the first status report and the second status report include buffer status information of the user equipment (UE).

20. The method according to claim 13, wherein the at least one first condition is satisfied when a talk or communication period is shifted to a silence period in a voice communication.

21. The method according to claim 20, wherein the at least one second condition is satisfied when the silence period is shifted to the talk or communication period in the voice communication.

22. The method according to claim 20, wherein the first status report and the second status report include information associated with a mode shift.

23. The method according to claim 20, wherein the first status report and the second status report are transmitted to the network according to a hybrid automatic repeat request (HARQ) scheme.
