Abstract

An apparatus and method for SF management in a broadband wireless communication system are provided. The apparatus includes a creator for creating a Service Flow (SF) management message including a plurality of SF identifiers to perform the same management for a plurality of SFs, and a transmitter for transmitting the management message created in the creator to an opponent node.

Claims

1. A wireless access node apparatus in a broadband wireless communication system, the apparatus comprising:

a creator for creating a Service Flow (SF) management message comprising a Service Flow IDentifier (SFID) list consisting of a plurality of SFIDs to perform the same management for a plurality of SFs; and

a transmitter for transmitting the management message created in the creator to a counterpart node.

2. The apparatus of claim 1, wherein the management message comprises at least one of a message for adding an SF, a message for changing at least one of SF encoding parameters of an SF, and a message for deleting an SF.

3. The apparatus of claim 1, wherein the counterpart node comprises at least one of a Mobile Station (MS) and a Base Station (BS).

4. The apparatus of claim 1, wherein the creator creates a management message comprising at least one of information on the quantity of the plurality of SFs, reference SF designation information, information on reference SF encoding parameters that are SF encoding parameters of the reference SF, and information on at least one of different SF encoding parameter of an SF other than the reference SF compared with the reference SF encoding parameters.

5. The apparatus of claim 1, further comprising:

a manager for performing at least one of creating, changing, and deleting the plurality of SFs by a batch process in response to the management message.

6. A wireless access node apparatus in a broadband wireless communication system, the apparatus comprising:

a receiver for receiving a Service Flow (SF) management message comprising a Service Flow IDentifier (SFID) list consisting of a plurality of SFIDs from a counterpart node; and

an analyzer for identifying management target SFs and management to be performed for the management target SFs by a batch process, by analyzing the management message.

7. The apparatus of claim 6, wherein the management message comprises at least one of a message for adding an SF, a message for changing at least one of SF encoding parameters of an SF, and a message for deleting an SF.

8. The apparatus of claim 6, wherein the opponent node comprises at least one of a Mobile Station (MS) and a Base Station (BS).

9. The apparatus of claim 6, wherein, using the management message, the analyzer identifies at least one of information on the quantity of the plurality of SFs, reference SF designation information, information on reference SF encoding parameters that are SF encoding parameters of the reference SF, and information on at least one of different SF encoding parameter of an SF other than the reference SF compared with the reference SF encoding parameters.

10. The apparatus of claim 6, further comprising:

a manager for performing at least one of creating, changing, and deleting the plurality of SFs by a batch process in response to the management message.

11. A Service Flow (SF) management method of a wireless access node in a broadband wireless communication system, the method comprising:

creating a Service Flow (SF) management message comprising a Service Flow IDentifier (SFID) list consisting of a plurality of SFIDs to perform the same management for a plurality of SFs; and

transmitting the created management message to a counterpart node.

12. The method of claim 11, wherein the management message comprises at least one of a message for adding an SF, a message for changing at least one of SF encoding parameters of an SF, and a message for deleting an SF.

13. The method of claim 11, wherein the opponent node comprises at least one of a Mobile Station (MS) and a Base Station (BS).

14. The method of claim 11, wherein the management message comprises at least one of information on the quantity of the plurality of SFs, reference SF designation information, information on reference SF encoding parameters that are SF encoding parameters of the reference SF, and information on at least one of different SF encoding parameters of an SF other than the reference SF compared with the reference SF encoding parameters.

15. The method of claim 11, further comprising:

performing at least one of creating, changing, and deleting the plurality of SFs by a batch process in response to the management message.

16. A Service Flow (SF) management method of a wireless access node in a broadband wireless communication system, the method comprising:

receiving a Service Flow (SF) management message comprising a Service Flow IDentifier (SFID) list consisting of a plurality of SFIDs from a counterpart node; and

identifying management target SFs and management to be performed for the management target SFs by a batch process, by analyzing the management message.

17. The method of claim 16, wherein the management message comprises at least one of a message for adding an SF, a message for changing at least one of SF encoding parameters of an SF, and a message for deleting an SF.
