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 mobile station, the method comprising:
receiving, from an access point, an extended capabilities element having an indication of support of prioritization of management frames;
receiving, from the access point, a management frame quality of service (MFQ) policy that defines an access category used for transmitting a first type of management frame; and
transmitting a policy configuration request to request a change to the MFQ policy,
wherein the MFQ policy comprises an MFQ policy element including an element ID field identifying the MFQ policy element, a length field indicating the length of the MFQ policy element, and a policy information field indicating a number of differences from a default MFQ policy.
2. The method of claim 1 , wherein management frames are distinct from signaling frames and content frames.
3. The method of claim 1 , wherein the policy configuration request includes an MFQ policy element indicative of the requested change.
4. The method of claim 1 , further comprising receiving, from the access point, a policy configuration response in response to the policy configuration request.
5. The method of claim 4 , wherein the policy configuration response includes an indication that the change has been accepted by the access point.
6. A mobile station, comprising:
a processor; and
memory storing instructions executable by the processor such that when executed, cause the processor to:
receive, from an access point, an extended capabilities element having an indication of support of prioritization of management frames;
receive, from the access point, a management frame quality of service (MFQ) policy that defines an access category used for transmitting a first type of management frame; and
transmit a policy configuration request to request a change to the MFQ policy,
wherein the MFQ policy comprises an MFQ policy element including an element ID field identifying the MFQ policy element, a length field indicating the length of the MFQ policy element, and a policy information field indicating a number of differences from a default MFQ policy.
7. The mobile station of claim 6 , wherein management frames are distinct from signaling frames and content frames.
8. The mobile station of claim 6 , wherein the policy configuration request includes an MFQ policy element indicative of the requested change.
9. The mobile station of claim 6 , wherein the processor is further configured to receive, from the access point, a policy configuration response in response to the policy configuration request.
10. The mobile station of claim 9 , wherein the policy configuration response includes an indication that the change has been accepted by the access point.
11. A method for an access point, the method comprising:
transmitting, to a mobile station, an extended capabilities element having an indication of support of prioritization of management frames;
transmitting, to the mobile station, a management frame quality of service (MFQ) policy that defines an access category used for transmitting a first type of management frame; and
receiving a policy configuration request to request a change to the MFQ policy,
wherein the MFQ policy comprises an MFQ policy element including an element ID field identifying the MFQ policy element, a length field indicating the length of the MFQ policy element, and a policy information field indicating a number of differences from a default MFQ policy.
12. The method of claim 11 , wherein management frames are distinct from signaling frames and content frames.
13. The method of claim 11 , wherein the policy configuration request includes an MFQ policy element indicative of the requested change.
14. The method of claim 11 , further comprising transmitting, to the mobile station, a policy configuration response in response to the policy configuration request.
15. The method of claim 14 , wherein the policy configuration response includes an indication that the change has been accepted by the access point.
16. An access point comprising:
a processor; and
memory storing instructions executable by the processor such that when executed, cause the processor to:
transmit, to a mobile station, an extended capabilities element having an indication of support of prioritization of management frames;
transmit, to the mobile station, a management frame quality of service (MFQ) policy that defines an access category used for transmitting a first type of management frame; and
receive, from the mobile station, a policy configuration request to request a change to the MFQ policy,
wherein the MFQ policy comprises an MFQ policy element including an element ID field identifying the MFQ policy element, a length field indicating the length of the MFQ policy element, and a policy information field indicating a number of differences from a default MFQ policy.
17. The access point of claim 16 , wherein management frames are distinct from signaling frames and content frames.
18. The access point of claim 16 , wherein the policy configuration request includes a MFQ policy element indicative of the requested change.
19. The access point of claim 16 , wherein the processor is further configured to transmit, to the mobile station, a policy configuration response to the mobile station in response to the policy configuration request.
20. The access point of claim 19 , wherein the policy configuration response includes an indication that the change has been accepted or rejected by the access point.
