Abstract

In a method of managing a multicast service, a mobile station receives a message including multicast service flow update information from a base station that belongs to a multicast group zone including a base station set having at least one base station. The mobile station updates a parameter associated with a multicast service flow of the multicast service based on the multicast service flow update information. The multicast service flow update information includes a new multicast group zone ID, current multicast service identification information, and new multicast service identification information mapped to the current multicast service identification information.

Claims

1. A method of managing a multicast service by a mobile station, the method comprising:

receiving the multicast service;

receiving a message including multicast service flow update information from a base station that belongs to a multicast group zone including a base station set having at least one base station; and

updating a parameter associated with a multicast service flow of the multicast service based on the multicast service flow update information,

wherein the multicast service flow update information includes a new multicast group zone identifier (ID), current multicast service identification information, and new multicast service identification information mapped to the current multicast service identification information.

2. The method of claim 1, wherein the current multicast service identification information includes a multicast group ID that is used for identifying the multicast service flow in a current multicast group zone, and

the new multicast service identification information includes a multicast group ID that is used for identifying the multicast service flow in a new multicast group zone.

3. The method of claim 1, wherein the current multicast service identification information includes a multicast group ID and a flow ID (FID) that are used for identifying the multicast service flow in a current multicast group zone, and

the new multicast service identification information includes a multicast group ID and an FID that are used for identifying the multicast service flow in a new multicast group zone.

4. The method of claim 1, wherein the message includes a neighbor advertisement (NBR-ADV) message that is periodically broadcast by the base station.

5. The method of claim 1, further comprising transmitting a ranging request (RNG-REQ) message to a base station, in a connected state, and

the message includes a ranging response (RNG-RSP) message that is transmitted in response to the RNG-REQ message.

6. The method of claim 1, further comprising transmitting an RNG-REQ message to the base station, in an idle state, and

the message includes an RNG-RSP message that is transmitted in response to the RNG-REQ message.

7. The method of claim 1, further comprising receiving a broadcast message including a multicast group zone ID to which the base station belongs.

8. A method of managing a multicast service by a base station that belongs to a multicast group zone including a base station set having at least one base station, the method comprising

generating multicast service flow update information for a multicast service flow of the multicast service provided to a mobile station;

and

transmitting a message including the multicast service flow update information to the mobile station,

wherein the multicast service flow update information includes a new multicast group zone identifier (ID), current multicast service identification information, and new multicast service identification information.

9. The method of claim 8, wherein the current multicast service identification information includes a multicast group ID that is used for identifying the multicast service flow in a current multicast group zone, and

the new multicast service identification information includes a multicast group ID that is used for identifying the multicast service flow in a new multicast group zone.

10. The method of claim 8, wherein the current multicast service identification information includes a multicast group ID and a flow ID (FID) that are used for identifying the multicast service flow in a current multicast group zone, and

the new multicast service identification information includes a multicast group ID and an FID that are used for identifying the multicast service flow in a new multicast group zone.

11. The method of claim 8, wherein the message includes a neighbor advertisement (NBR-ADV) message that is periodically broadcast by the base station.

12. The method of claim 8, further comprising receiving a ranging request (RNG-REQ) message from the mobile station when the mobile station is in a connected state, and

the message includes a ranging response (RNG-RSP) message that is transmitted in response to the RNG-REQ message.

13. The method of claim 8, further comprising receiving an RNG-REQ message from the mobile station when the mobile station is in an idle state, and

the message includes an RNG-RSP message that is transmitted in response to the RNG-REQ message.

14. The method of claim 8, further comprising receiving a broadcast message including a multicast group zone ID to which the base station belongs.

15. An apparatus for managing a multicast service, the apparatus comprising:

a transceiver configured to receive the multicast service, and to receive a message including multicast service flow update information from a base station that belongs to a multicast group zone including a base station set having at least one base station; and

a controller configured to update a parameter associated with a multicast service flow of the multicast service based on the multicast service flow update information,

wherein the multicast service flow update information includes a new multicast group zone identifier (ID), current multicast service identification information, and new multicast service identification information mapped to the current multicast service identification information.

16. The apparatus of claim 15, wherein the current multicast service identification information includes a multicast group ID that is used for identifying the multicast service flow in a current multicast group zone, and

the new multicast service identification information includes a multicast group ID that is used for identifying the multicast service flow in a new multicast group zone.

17. The apparatus of claim 15, wherein the current multicast service identification information includes a multicast group ID and a flow ID (FID) that are used for identifying the multicast service flow in a current multicast group zone, and

the new multicast service identification information includes a multicast group ID and an FID that are used for identifying the multicast service flow in a new multicast group zone.

18. An apparatus for managing a multicast service by a base station that belongs to a multicast group zone including a base station set having at least one base station, the apparatus comprising:

a controller configured to generate multicast service flow update information for a multicast service flow of the multicast service provided to a mobile station; and

a transceiver configured to transmit a message including the multicast service flow update information to the mobile station,

wherein the multicast service flow update information includes a new multicast group zone identifier (ID), current multicast service identification information, and new multicast service identification information.

19. The apparatus of claim 18, wherein the current multicast service identification information includes a multicast group ID that is used for identifying the multicast service flow in a current multicast group zone, and

the new multicast service identification information includes a multicast group ID that is used for identifying the multicast service flow in a new multicast group zone.

20. The apparatus of claim 18, wherein the current multicast service identification information includes a multicast group ID and a flow ID (FID) that are used for identifying the multicast service flow in a current multicast group zone, and

the new multicast service identification information includes a multicast group ID and an FID that are used for identifying the multicast service flow in a new multicast group zone.
