Abstract

A method for managing a service flow of a mobile subscriber station (MSS) in a serving base station (BS) for a mobile communication system including the serving BS in communication with the MSS through a wireless access channel, and at least one active BS included in an active BS set of the MSS. Upon receiving a service flow management request from the MSS, the serving BS updates a service flow with the MSS, and transmits the updated service flow to the active BS using a predetermined message. Upon receiving a response message for the updated service flow from the active BS, the serving BS transmits service flow information of each active BS included in the response message to the MSS.

upon receiving a service flow management request from the MSS, updating a service flow with the MSS;

transmitting the updated service flow to the active BS using a predetermined message; and

upon receiving a response message for the updated service flow from the active BS, transmitting service flow information of each active BS included in the response message to the MSS.

2. The method of claim 1, wherein if the service flow management request from the MSS is a service flow addition request, the serving BS further performs:

adding a service flow with the MSS;

transmitting the added service flow to the active BS using a predetermined message; and

upon receiving a response message for the added service flow from the active BS, transmitting service flow information of each active BS included in the response message to the MSS.

3. The method of claim 1, wherein if the service flow management request from the MSS is a service flow change request, the serving BS further performs:

changing a service flow with the MSS;

transmitting the changed service flow to the active BS using a predetermined message; and

upon receiving a response message for the changed service flow from the active BS, transmitting service flow information of each active BS included in the response message to the MSS.

4. The method of claim 1, wherein if the service flow management request from the MSS is a service flow deletion request, the serving BS further performs:

deleting a service flow with the MSS;

transmitting the deleted service flow to the active BS using a predetermined message; and

upon receiving a response message for the deleted service flow from the active BS, transmitting service flow information of each active BS included in the response message to the MSS.

5. The method of claim 1, further comprising the step of, upon receiving the service flow management request from the MSS, transmitting a predetermined message to the MSS in response to the service flow management request.

6. The method of claim 1, further comprising:

transmitting to the MSS a response message including predetermined information informing the active BS that the serving BS is a serving BS; and

transmitting information on the MSS that has requested update of the service flow, to the active BS.

7. A method for managing a service flow in a mobile subscriber station (MSS) for a mobile communication system including the MSS in communication with a serving base station (BS) though a wireless access channel, and at least one active BS included in an active BS set of the MSS, with the exception of the serving BS, the method comprising:

upon occurrence of a service flow management request, transmitting a predetermined service flow update message to the serving BS; and

receiving a response to the service flow update message from the serving BS, and updating a service flow based on the received response.

8. The method of claim 7, wherein if the service flow management request is a service flow addition request, the MSS further performs:

transmitting a predetermined message for addition of a service flow to the serving BS; and

receiving a response for the added service flow from the serving BS, and adding a new service flow based on the received response.

9. The method of claim 7, wherein if the service flow management request is a service flow change request, the MSS further performs:

transmitting a predetermined message for change of a service flow to the serving BS; and

receiving a response for the changed service flow from the serving BS, and changing a service flow based on the received response.

10. The method of claim 7, wherein if the service flow management request is a service flow deletion request, the MSS further performs:

transmitting a predetermined message for deletion of a service flow to the serving BS; and

receiving a response for the deleted service flow from the serving BS, and deleting a service flow according to the received response.

11. A method for adding a service flow of a mobile subscriber station (MSS) in a serving base station (BS) for a mobile communication system including the serving BS in communication with the MSS through a wireless access channel, and at least one active BS included in an active BS set of the MSS, the method comprising:

upon receiving a service flow addition request from the MSS, adding a service flow identifier (ID);

transmitting the added service flow ID to the active BS using a predetermined message; and

upon receiving a response message with the added service flow ID from the active BS, allocating a new connection ID to the MSS.

12. The method of claim 11, further comprising receiving a dynamic service addition request (DSA-REQ) message when the MSS requests addition of the service flow.

13. The method of claim 11, wherein the active BSs have the same service flow ID and different connection IDs for connections being set up to the MSS.

14. The method of claim 11, further comprising transmitting a dynamic service addition response (DSA-RSP) message to the MSS upon receiving a response message with the added service flow ID from the active BSs.

15. A method for changing a service flow of a mobile subscriber station (MSS) in a serving base station (BS) for a mobile communication system including the serving BS in communication with the MSS through a wireless access channel, and at least one active BS included in an active BS set of the MSS, the method comprising:

upon receiving a service flow change request from the MSS, changing a service flow identifier (ID);

transmitting the changed service flow ID to the active BS using a predetermined message; and

upon receiving a response message with the changed service flow ID from the active BS, transmitting information on the changed service flow to the MSS.

16. The method of claim 15, further comprising receiving a dynamic service change request (DSC-REQ) message when the MSS requests change of the service flow.

17. The method of claim 15, wherein the active BSs have the same service flow ID and different connection IDs for connections being set up to the MSS.

18. The method of claim 15, further comprising transmitting a dynamic service change response (DSC-RSP) message to the MSS upon receiving a response message with the changed service flow ID from the active BSs.

19. A method for deleting a service flow of a mobile subscriber station (MSS) in a serving base station (BS) for a mobile communication system including the serving BS in communication with the MSS through a wireless access channel, and at least one active BS included in an active BS set of the MSS, the method comprising:

upon receiving a service flow deletion request from the MSS, deleting a service flow identifier (ID);

transmitting the deleted service flow ID to the active BS using a predetermined message; and

informing the MSS of deletion of a connection ID.

20. The method of claim 19, further comprising receiving a dynamic service deletion request (DSD-REQ) message when the MSS requests deletion of the service flow.

21. The method of claim 19, wherein the active BSs have the same service flow ID and different connection IDs for connections being set up to the MSS.
