Method and apparatus used in WLAN networks
The application provides a method, method, comprising: a station (STA) sending a first quality of service (QoS) request message to an access point (AP) indicating a requested QoS for a traffic stream from the AP to the STA; the AP receiving the first QoS request message from the STA and sending a first traffic stream applied with the requested QoS to the STA when the requested QoS matches with an existing QoS policy for the STA in the AP or there is no existing QoS policy for the STA in the AP, and the STA receiving the first traffic stream applied with the requested QoS from AP.
1. An access point (AP) comprising:
a wireless medium; and
processor circuitry coupled to the wireless medium and configured to:
tentatively allocate network resources in the AP;
send a quality of service (QOS) request message to a station (STA) that indicates a requested QOS for a traffic stream from the AP to the STA based on the tentatively allocated network resources;
receive a response message from the STA that indicates the STA accepts or rejected the requested QOS;
finalize the allocation of the network resources in the AP in response to receiving a response message from the STA that indicates the STA accepts the requested QOS; and
send traffic streams applied with the requested QoS to the STA.
2. The AP of claim 1 , wherein the processor circuitry is further configured to:
send an updated QoS request message to the STA that indicates an updated requested QoS for a traffic stream from the AP to the STA in response to a change in the requested QOS;
receive a response message from the STA that indicates the STA accepts or refuses the updated requested QOS; and
send the traffic streams applied with the updated requested QOS to the STA in response to receiving the response message from the STA that indicates the STA accepts the updated requested QoS.
3. The AP of claim 2 , wherein the STA accepts or refuses the updated requested QoS based on current network conditions, policies or application priorities.
4. The AP of claim 1 , wherein the processor circuitry is further configured to:
receive an updated QOS request message from the STA that indicates an updated requested QOS for a traffic stream from the AP to the STA;
send a response message to the STA that indicates the AP accepts or refuses the updated requested QoS, and
send traffic streams applied with the updated requested QOS to the STAP when the AP accepts the updated requested QoS.
5. The AP of claim 4 , wherein the AP accepts or refuses the updated requested QoS based on current network conditions, policies or application priorities.
6. The AP of claim 1 , wherein the AP tentatively allocate network resources based on current network conditions, policies and application priorities.
7. The AP of claim 1 , wherein the STA accepts or refuses the requested QoS based on current network conditions, policies or application priorities.
8. A method comprising:
an access point (AP) tentatively allocating network resources in the AP;
the AP sending a quality of service (QOS) request message to a station (STA) that indicates a requested QoS for a traffic stream from the AP to the STA based on the tentatively allocated network resources;
the STA sending a response message to the AP that indicates the STA accepts or refuses the requested QoS in response to receiving the QoS request message from the AP;
the AP finalizing the allocation of the network resources in the AP in response to receiving the response message from the STA that indicates the STA accepts the requested QoS, and sending traffic streams applied with the requested QOS to the STA; and
the STA receiving traffic streams applied with the requested QOS from the AP.
9. The method of claim 8 , further comprising:
the AP sending an updated QOS request message to the STA that indicates an updated requested QoS for a traffic stream from the AP to the STA in response to a change in the requested QoS;
the STA sending a response message to the AP that indicates the STA accepts or refuses the updated requested QoS in response to receiving the updated QoS request message from the AP;
the AP sending traffic streams applied with the updated requested QoS to the STA in response to receiving the updated response message from the STA that indicates the STA accepts the updated requested QoS; and
the STA receiving the traffic streams applied with the updated requested QOS the AP.
10. The method of claim 9 , wherein the STA accepts or refuses the updated requested QoS based on current network conditions, policies or application priorities.
11. The method of claim 8 , further comprising:
the STA sending an updated QoS request message to the AP that indicates an updated requested QoS for a traffic stream from the AP to the STA in response to a change in the requested QOS;
the AP sending a response message to the STA that indicates the AP accepts or refuses the updated requested QoS in response to receiving the updated QoS request message from the STA;
the AP sending traffic streams applied with the updated requested QoS when the AP accepts the updated requested QOS; and
the STA receiving the traffic streams applied with the updated requested QOS from the AP.
12. The method of claim 11 , wherein the AP accepts or refuses the updated requested QoS based on current network conditions, policies or application priorities.
13. The method of claim 8 , wherein the AP tentatively allocate network resources based on current network conditions, policies and application priorities.
14. The method of claim 8 , wherein the STA accepts or refuses the requested QoS based on current network conditions, policies or application priorities.
15. A non-transitory computer readable medium with instructions stored thereon, when executed by a processor, cause an access point (AP) to:
tentatively allocate network resources in the AP; send a quality of service (QOS) request message to a station (STA) that indicates a requested QoS for a traffic stream from the AP to the STA based on the tentatively allocated network resources;
receive a response message from the STA that indicates the STA accepts or rejected the requested QOS;
finalize the allocation of the network resources in the AP in response to receiving a response message from the STA that indicates the STA accepts the requested QOS; and
send traffic streams applied with the requested QoS to the STA.
16. The non-transitory computer readable medium of claim 15 , wherein the instructions, when executed by a processor, further cause the AP to:
send an updated QoS request message to the STA that indicates an updated requested QoS for a traffic stream from the AP to the STA in response to a change in the requested QOS;
receive a response message from the STA that indicates the STA accepts or refuses the updated requested QOS; and
send the traffic streams applied with the updated requested QoS to the STA in response to receiving the response message from the STA that indicates the STA accepts the updated requested QoS.
17. The non-transitory computer readable medium of claim 16 , wherein the STA accepts or refuses the updated requested QoS based on current network conditions, policies or application priorities.
18. The non-transitory computer readable medium of claim 15 , wherein the instructions, when executed by a processor, further cause the AP to:
receive an updated QOS request message from the STA that indicates an updated requested QoS for a traffic stream from the AP to the STA;
send a response message to the STA that indicates the AP accepts or refuses the updated requested QoS, and
send traffic streams applied with the updated requested QoS to the STAP when the AP accepts the updated requested QoS.
