Abstract

An access point advertises a management frame quality of service (MFQ) policy that defines an access category used for transmitting a first type of management frame. Each mobile station associated with the access point is to prioritize transmission of management frames according to the MFQ policy advertised by the access point, unless a policy configuration request for the mobile station to prioritize transmission of management frames according to a different MFQ policy has been accepted.

Claims

1. A method for a wireless station, the method comprising:

transmitting a management frame quality of service (MFQ) policy configuration request to an access point, the request requesting a change in a MFQ policy used to transmit management frames between the wireless station and the access point;

receiving, from the access point, a MFQ policy configuration response, wherein the MFQ policy configuration response includes a MFQ policy element and a status code, and wherein the status code indicates whether the access point has accepted or rejected the change in the MFQ policy;

transmitting any subsequent management frames to the access point in accordance with the change to the MFQ policy in response to the status code indicating that the access point has accepted the change in the MFQ policy; and

transmitting management frames to the access point in accordance with a previously configured MFQ policy in response to the status code indicating that the access point has rejected the change in the MFQ policy.

2. The method as claimed in claim 1, wherein the MFQ policy configuration request includes a MFQ policy element indicative of the requested change.

3. The method as claimed in claim 1, wherein the MFQ policy configuration response is received in response to the MFQ policy configuration request.

4. The method as claimed in claim 3, further comprising:

transmitting, to the access point, a second MFQ policy configuration request to request a second change.

5. The method as claimed in claim 4, wherein the second MFQ policy configuration request is different from the first MFQ policy configuration request.

6. The method as claimed in claim 4, wherein the second MFQ policy configuration request is the same as the first MFQ policy configuration request.

7. A method for an access point, the method comprising:

receiving, from a wireless station, a management frame quality of service (MFQ) policy configuration request requesting a change in a MFQ policy used to transmit management frames between the wireless station and the access point;

transmitting, by the access point a MFQ policy configuration response, wherein the MFQ policy configuration response includes a MFQ policy element and a status code, wherein the status code indicates whether the access point has accepted or rejected the change in the MFQ policy;

receiving any subsequent management frames from the wireless station transmitted in accordance with the change to the MFQ policy when the status code indicates that the access point has accepted the change in the MFQ policy; and

receiving management frames from the wireless station transmitted in accordance with a previously configured MFQ policy when the status code indicates that the access point has rejected the change in the MFQ policy.

8. The method as claimed in claim 7, wherein the MFQ policy configuration request includes a MFQ policy element indicative of the requested change.

9. The method as claimed in claim 7, wherein the MFQ policy configuration response is transmitted in response to the MFQ policy configuration request.

10. A wireless station comprising:

a processor configured to;

transmit a management frame quality of service (MFQ) policy configuration request to an access point, the request requesting a change in a MFQ policy used to transmit management frames between the wireless station and the access point;

receive, from the access point, a MFQ policy configuration response, wherein the MFQ policy configuration response includes a MFQ policy element and a status code, wherein the status code indicates whether the access point has accepted or rejected the change in the MFQ policy;

transmit any subsequent management frames to the access point in accordance with the change to the MFQ policy in response to the status code indicating that the access point has accepted the change in the MFQ policy; and

transmit management frames to the access point in accordance with a previously configured MFQ policy in response to the status code indicating that the access point has rejected the change in the MFQ policy.

11. The wireless station as claimed in claim 10, wherein the MFQ policy configuration request includes a MFQ policy element indicative of the requested change.

12. The wireless station as claimed in claim 10, wherein the MFQ policy configuration response is received in response to the MFQ policy configuration request.

13. An access point comprising:

a processor configured to;

receive, from a wireless station, a management frame quality of service (MFQ) policy configuration request requesting a change in a MFQ policy used to transmit management frames between the wireless station and the access point;

transmit, by the access point, a MFQ policy configuration response, wherein the MFQ policy configuration response includes a MFQ policy element and a status, wherein the status code indicates whether the access point has accepted or rejected the change in the MFQ policy;

receive any subsequent management frames from the wireless station transmitted in accordance with the change to the MFQ policy when the status code indicates that the access point has accepted the change in the MFQ policy; and

receive management frames from the wireless station transmitted in accordance with a previously configured MFQ policy when the status code indicates that the access point has rejected the change in the MFQ policy.

14. The access point as claimed in claim 13, wherein the MFQ policy configuration request includes a MFQ policy element indicative of the requested change.

15. The access point as claimed in claim 13, wherein the MFQ policy configuration response is transmitted in response to the MFQ policy configuration request.
