Abstract

The object of the present invention is to provide a reporting strategy for uplink scheduling request information in wireless telecommunication network. Above all, a method for the user equipment to report the uplink scheduling request information to the base station in wireless telecommunication network is disclosed. Firstly, the user equipment computes the overall service data amount of all radio bearers in each group of radio bearers in the buffer of the user equipment; then the user equipment only reports group-related information of triggered one or more groups of radio bearers to the base station. The present invention further proposes a method in the user equipment in wireless telecommunication network for reporting the emergency information to the base station, that is, the user equipment judges whether each radio bearer is in the emergency, and when one or more radio bearers are in the emergency, the user equipment sends emergency indication information to the base station. By the combination of the two reporting method, the base station can realize efficient and fair scheduling.

Claims

1. A method in a user equipment in wireless telecommunication network for reporting request information for uplink scheduling to a base station, comprising the steps of:

a. computing the overall service data amount of all radio bearers in each group of radio bearers in the buffer of said user equipment, wherein, each group of radio bearers comprises one or more radio bearers with the same priority;

b. only reporting group-related information of triggered one or more groups of radio bearers to said base station.

2. A method according to claim 1, characterized in that, said step b comprises the steps of:

judging whether said each group of radio bearers is triggered;

when one or more groups of radio bearers therein are triggered, sending group-related information of said triggered one or more groups of radio bearers to said base station.

3. A method according to claim 2, characterized in that, said step of judging whether said each group of radio bearers is triggered comprises:

when the predefined report time of said one or more groups of radio bearers arrives, judging said one or more groups of radio bearers are triggered.

4. A method according to claim 3, characterized in that, said predefined report time is periodical.

5. A method according to claim 1, characterized in that, said step of judging whether said each group of radio bearers is triggered comprises:

when the overall service data amount of one or more groups of radio bearers in the buffer of said user equipment exceeds or is lower than the corresponding predefined threshold, judging said one or more groups of radio bearers are triggered.

6. A method according to claim 1, characterized in that, group-related information of said each group of radio bearers is sent to said base station via the data frame on the media access control layer.

7. A method according to claim 1, characterized in that, group-related information of said each group of radio bearers is sent to said base station via a new control protocol data unit.

8. A method in a user equipment in wireless telecommunication network for reporting request information for uplink scheduling to a base station, comprising the steps of:

computing the overall service data amount of all radio bearers in each group of radio bearers in the buffer of said user equipment, wherein, each group of radio bearers comprises one or more radio bearers with the same priority; and

only reporting group-related information of triggered one or more groups of radio bearers to said base station;

wherein said group-related information comprises the number of said triggered groups of radio bearers, the group indicator of each of said triggered groups of radio bearers and the overall data amount of each of said triggered groups of radio bearers.

9. A reporting device in a user equipment in wireless telecommunication network for reporting request information for uplink scheduling to a base station, comprising:

a computing means for computing the overall service data amount of all radio bearers in each group of radio bearers in the buffer of said user equipment, wherein, each group of radio bearers comprises one or more radio bearers with the same priority;

a controlled sending means for only reporting group-related information of triggered one or more groups of radio bearers to said base station.

10. A reporting device according to claim 9, characterized in that, said controlled sending means comprises:

a judging means for judging whether said each group of radio bearers is triggered;

a sending means for when one or more groups of radio bearers therein are triggered, sending group-related information of said triggered one or more groups of radio bearers to said base station.

11. A reporting device according to claim 10, characterized in that, said judging means is further used for when the overall service data amount of one or more groups of radio bearers in the buffer of said user equipment exceeds or is lower than the corresponding predefined threshold, judging said one or more groups of radio bearers are triggered.

12. A reporting device according to claim 10, characterized in that, said judging means is further used for when the predefined report time of said one or more groups of radio bearers arrives, judging said one or more groups of radio bearers are triggered.

13. A reporting device according to claim 12, characterized in that, said predefined report time is periodical.

14. A reporting device according to claim 9, characterized in that, group-related information of said each group of radio bearers is sent to said base station via the data frame on the media access control layer.

15. A reporting device according to claim 9, characterized in that, group-related information of said each group of radio bearers is sent to said base station via a new control protocol data unit.

16. A reporting device in a user equipment in wireless telecommunication network for reporting request information for uplink scheduling to a base station comprising:

a computing means for computing the overall service data amount of all radio bearers in each group of radio bearers in the buffer of said user equipment, wherein, each group of radio bearers comprises one or more radio bearers with the same priority; and
