Negotiation of quality of service (QoS) information for network management traffic in a wireless local area network (WLAN)
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.
1. A method for a wireless station, the method comprising:
transmitting, to an access point, a management frame quality of service (MFQ) policy configuration request requesting a change in a MFQ policy, wherein the MFQ policy configuration request includes a first dialog token having a length of 8 bits and wherein the first dialog token is set to a first value by the wireless station;
receiving, from the access point, a MFQ policy configuration response, wherein the MFQ policy configuration response includes a MFQ policy element and a second dialog token having a length of 8 bits; and
transmitting any subsequent management frames to the access point in accordance with changes to the MFQ policy when the second dialog token is the same as the first dialog token.
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 , wherein the MFQ policy configuration response includes a status code indicating whether the access point has accepted or rejected the change in the MFQ policy.
5. The method as claimed in claim 1 , wherein the wireless station sets the first dialog token to the first value to keep track of the MFQ policy configuration request.
6. 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, wherein the MFQ policy configuration request includes a first dialog token having a length of 8 bits and wherein the first dialog token is set to a first value by the wireless station;
transmitting, by the access point, a MFQ policy configuration response, wherein the MFQ policy configuration response includes a MFQ policy element and a second dialog token having a length of 8 bits; and
receiving any subsequent management frames transmitted from the wireless station in accordance to the change in the MFQ policy when the second dialog token is the same as the first dialog token.
7. The method as claimed in claim 6 , wherein the MFQ policy configuration request includes a MFQ policy element indicative of the requested change.
8. The method as claimed in claim 6 , wherein the MFQ policy configuration response is transmitted in response to the MFQ policy configuration request.
9. The method as claimed in claim 8 , wherein the MFQ policy configuration response includes a status code indicating whether the access point has accepted or rejected the change in the MFQ policy.
10. The method as claimed in claim 6 , wherein the wireless station sets the first dialog token to the first value to keep track of the MFQ policy configuration request.
11. A wireless station comprising:
a processor configured to:
transmit, to an access point, a management frame quality of service (MFQ) policy configuration request requesting a change in a MFQ policy, wherein the MFQ policy configuration request includes a first dialog token having a length of 8 bits and wherein the first dialog token is set to a first value by the wireless station;
receive, from the access point, a MFQ policy configuration response, wherein the MFQ policy configuration response includes a MFQ policy element and a second dialog token having a length of 8 bits; and
transmit any subsequent management frames to the access point in accordance with changes to the MFQ policy when the second dialog token is the same as the first dialog token.
12. The wireless station as claimed in claim 11 , wherein the MFQ policy configuration request includes a MFQ policy element indicative of the requested change.
13. The wireless station as claimed in claim 11 , wherein the MFQ policy configuration response is received in response to the MFQ policy configuration request.
14. The wireless station as claimed in claim 13 , wherein the MFQ policy configuration response includes a status code indicating whether the access point has accepted or rejected the change in the MFQ policy.
15. The wireless station as claimed in claim 11 , wherein the wireless station sets the first dialog token to the first value to keep track of the MFQ policy configuration request.
16. 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, wherein the MFQ policy configuration request includes a first dialog token having a length of 8 bits and wherein the first dialog token is set to a first value by the wireless station;
transmit, by the access point, a MFQ policy configuration response, wherein the MFQ policy configuration response includes a MFQ policy element and a second dialog token having a length of 8 bits; and
receive any subsequent management frames transmitted from the wireless station in accordance to the change in the MFQ policy when the second dialog token is the same as the first dialog token.
17. The access point as claimed in claim 16 , wherein the MFQ policy configuration request includes a MFQ policy element indicative of the requested change.
18. The access point as claimed in claim 16 , wherein the MFQ policy configuration response is transmitted in response to the MFQ policy configuration request.
19. The access point as claimed in claim 18 , wherein the MFQ policy configuration response includes a status code indicating whether the access point has accepted or rejected the change in the MFQ policy.
20. The access point as claimed in claim 16 , wherein the wireless station sets the first dialog token to the first value to keep track of the MFQ policy configuration request.
