Abstract

Disclosed are a method for identifying a connection, mobile station and base station. The method comprises the steps of: assigning a MS ID to the mobile station when the mobile station enters into the coverage area of the base station; and assigning a connection ID to a connection when the connection is established between the base station and the mobile station. With the proposed solution, the data overhead could be reduced due to short Connection ID instead of 16-bit CID in 802.16e, especially for VoIP traffic. In addition, due to adjustable bit-length of Connection ID, the tuple <MS ID, Connection ID>could flexibly support different numbers of connections while keeping overhead in minimal.

Claims

1. A method for identifying a connection between a base station and a mobile station, comprising the steps of:

assigning a MS ID to the mobile station when the mobile station enters into the coverage area of the base station; and

assigning a connection ID to a connection when the connection is established between the base station and the mobile station.

2. The method as claim 1, wherein the MS ID is unique in the domain of cell or sector while the connection ID is unique in the domain of the mobile station.

3. The method of claim 1, wherein the MS ID is denoted with m bits and the connection ID is denoted with n bits, wherein m and n are integer.

4. The method of claim 3, further comprising a step of adding at least one bit to the connection ID.

5. The method of claim 3, wherein the connection IDs for the specific mobile station have the same length.

6. The method of claim 3, wherein a set of connection IDs is reserved for signaling connections.

10. The method of claim 3, further comprising a step of allocating radio resources for each mobile station based on the MS ID.

11. The method of claim 3, further comprising a step of updating the MS ID in the case of the mobile station moves from the coverage area of the base station to the coverage area of another base station.

12. The method of claim 11, wherein the connection ID for the mobile station is maintained when the mobile station moves from the coverage area of the base station to the coverage area of another base station.

13. The method of claim 10, wherein the step of allocating radio resources for each mobile station based on the MS ID comprises the steps of:

allocating at least one resource block for a downlink based on the MS ID; and

allocating at least one resource block for a uplink based on the MS ID.

14. The method of claim 13, wherein when transmitting, the resource block is filled with MAC PDUs whose header contains a field containing n-bit Connection ID.

7-9. -9. (canceled)

15. A base station for identifying a connection between the base station and a mobile station, comprising:

first assignment means for assigning a MS ID to the mobile station when the mobile station enters into the coverage area of the base station; and

second assignment means for assigning a connection ID to a connection when the connection is established between the base station and the mobile station.

16. The base station of claim 15, wherein the MS ID is unique in the domain of cell or sector while the connection ID is unique in the domain of the mobile station.

17-28. -28. (canceled)

29. A mobile station, which is identified by a MS ID assigned from a base station, comprising:

receiving means for receiving a message including a connection ID; and

establishing a connection with the base station based on the connection ID.

30-37. -37. (canceled)
