Abstract

A method and apparatus for performing traffic engineering, e.g., allocating bandwidth, on a wireless access network are disclosed. For example, the method determines a number of subscriber stations (SSs) that a Base Station (BS) is capable of supporting in accordance with at least one performance objective for voice traffic, wherein the at least one performance objective for voice traffic comprises a type of codec. The method then allocates bandwidth by the base station in accordance with the number of subscriber stations that the base station is capable of supporting.

First claim

What is claimed is:

1. A method for allocating a bandwidth for a network, the method comprising:
determining, by a base station, a number of subscriber stations that the base station is capable of supporting in accordance with a performance objective for data traffic and a performance objective for voice traffic, wherein the performance objective for data traffic comprises an active factor, wherein the performance objective for voice traffic comprises a load per voice line, wherein the determining is performed using an equivalent bandwidth model; and
allocating, by the base station, the bandwidth in accordance with the number of subscriber stations that the base station is capable of supporting.

2. The method of claim 1 , further comprising:
monitoring an actual load for each of the subscriber stations;
monitoring an actual blocking for each of the subscriber stations;
determining whether each of the subscriber stations is conforming or non-conforming to a negotiated load level for each of the subscriber stations; and
determining whether or not each of the subscriber stations is blocked in accordance with a negotiated blocking target.

3. The method of claim 2 , further comprising:
applying a first blocking scheme to a subscriber station that is determined to be non-conforming so that the subscriber station that is determined to be non-conforming is limited to its negotiated load level.

4. The method of claim 3 , further comprising:
performing a second blocking scheme that redistributes a blocking rate among a plurality of active voice lines.

5. The method of claim 1 , wherein the performance objective for the data traffic for each of the subscriber stations further comprises an allowable peak rate.

6. The method of claim 1 , wherein the voice traffic is treated with a highest priority by the base station versus the data traffic.

7. The method of claim 6 , wherein the voice traffic and the data traffic use separate queues at the base station.

8. The method of claim 1 , wherein the network is a wireless access network.

9. A non-transitory computer-readable storage medium storing a plurality of instructions which, when executed by a processor of a base station, cause the processor to perform operations for allocating a bandwidth for a network, the operations comprising:
determining a number of subscriber stations that the base station is capable of supporting in accordance with a performance objective for data traffic and a performance objective for voice traffic, wherein the performance objective for data traffic comprises an active factor, wherein the performance objective for voice traffic comprises a load per voice line, wherein the determining is performed using an equivalent bandwidth model; and
allocating the bandwidth in accordance with the number of subscriber stations that the base station is capable of supporting.

10. The non-transitory computer-readable storage medium of claim 9 , further comprising:
monitoring an actual load for each of the subscriber stations;
monitoring an actual blocking for each of the subscriber stations;
determining whether each of the subscriber stations is conforming or non-conforming to a negotiated load level for each of the subscriber stations; and
determining whether or not each of the subscriber stations is blocked in accordance with a negotiated blocking target.

11. The non-transitory computer-readable storage medium of claim 10 , further comprising:
applying a first blocking scheme to a subscriber station that is determined to be non-conforming so that the subscriber station that is determined to be non-conforming is limited to its negotiated load level.

12. The non-transitory computer-readable storage medium of claim 11 , further comprising:
performing a second blocking scheme that redistributes a blocking rate among a plurality of active voice lines.

13. The non-transitory computer-readable storage medium of claim 9 , wherein the performance objective for the data traffic for each of the subscriber stations further comprises an allowable peak rate.

14. The non-transitory computer-readable storage medium of claim 9 , wherein the voice traffic is treated with a highest priority by the base station versus the data traffic.

15. The non-transitory computer-readable storage medium of claim 14 , wherein the voice traffic and the data traffic use separate queues at the base station.

16. The non-transitory computer-readable storage medium of claim 9 , wherein the network is a wireless access network.

17. An apparatus for allocating a bandwidth for a network, the apparatus comprising:
a processor of a base station; and
a computer-readable medium storing a plurality of instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising:
determining a number of subscriber stations that the base station is capable of supporting in accordance with a performance objective for data traffic and a performance objective for voice traffic, wherein the performance objective for data traffic comprises an active factor, wherein the performance objective for voice traffic comprises a load per voice line, wherein the determining is performed using an equivalent bandwidth model; and
allocating the bandwidth in accordance with the number of subscriber stations that the base station is capable of supporting.

18. The apparatus of claim 17 , the operations further comprising:
monitoring an actual load for each of the subscriber stations;
monitoring an actual blocking for each of the subscriber stations;
determining whether each of the subscriber stations is conforming or non-conforming to a negotiated load level for each of the subscriber stations; and
determining whether or not each of the subscriber stations is blocked in accordance with a negotiated blocking target.

19. The apparatus of claim 18 , the operations further comprising:
applying a first blocking scheme to a subscriber station that is determined to be non-conforming so that the subscriber station that is determined to be non-conforming is limited to its negotiated load level.

20. The apparatus of claim 19 , the operations further comprising:
performing a second blocking scheme that redistributes a blocking rate among a plurality of active voice lines.
