Abstract

Claims (48)

1 . A method for providing network initiated Wi-Fi Stream Classification Service (SCS), the method comprising:

negotiating, by a computing device, SCS flow parameters;

provisioning, by the computing device, a flow using the SCS flow parameters;

determining, by a computing device, a Station (STA) associates with an Access Point (AP);

allowing, by the computing device, the STA to communicate with the AP using the flow according to the SCS flow parameters;

receiving, by the computing device, a request for unique SCS parameters from the STA; and

merging, by the computing device, the unique SCS parameters with the SCS flow parameters to generate merged SCS flows.

2 . The method of claim 1 , wherein the SCS flow parameters include any one of (i) a delay bound, (ii) a Scheduling Interval (SI), (iii) a Quality of Service (QoS) mapping, or (iv) any combination of (i)-(iii).

3 . The method of claim 1 , wherein the SCS flow parameters are for a specific flow supported at the STA or for a class of flows supported by a class of STAs.

4 . The method of claim 1 , further comprising:

informing the STA of active SCS sessions by sending the merged SCS flows to the STA.

5 . The method of claim 1 , further comprising:

receiving a request from the STA to associate with a second AP; and

updating the SCS flow parameters based on the association with the second AP.

6 . The method of claim 1 , further comprising:

receiving a request from the STA to associate with a second AP, wherein the request includes a SCS ID identifying the SCS flow parameters; and

confirming the SCS flow parameters identified by the SCS ID.

7 . A system for providing network initiated Wi-Fi Stream Classification Service (SCS), the system comprising:

a memory storage; and

a processing unit coupled to the memory storage, wherein the processing unit is operative to:

negotiate SCS flow parameters;

provision a flow using the SCS flow parameters;

determine a Station (STA) associates with an Access Point (AP);

allow the STA to communicate with the AP using the flow according to the SCS flow parameters;

receive a request from the STA to associate with a second AP, wherein the request includes a SCS ID identifying the SCS flow parameters; and

confirm the SCS flow parameters identified by the SCS ID.

8 . The system of claim 7 , wherein the SCS flow parameters include any one of (i) a delay bound, (ii) a Scheduling Interval (SI), (iii) a Quality of Service (QoS) mapping, or (iv) any combination of (i)-(iii).

9 . The system of claim 7 , wherein the SCS flow parameters are for a specific flow supported at the STA or for a class of flows supported by a class of STAs.

10 . The system of claim 7 , the processing unit being further operative to:

receive a request for unique SCS parameters from the STA; and

merge the unique SCS parameters with the SCS flow parameters to generate merged SCS flows.

11 . The system of claim 10 , the processing unit being further operative to: inform the STA of active SCS sessions by sending the merged SCS flows to the STA.

12 . The system of claim 7 , the processing unit being further operative to: receive a request from the STA to associate with a second AP; and

update the SCS flow parameters based on the association with the second AP.

13 . A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method for providing network initiated Wi-Fi Stream Classification Service (SCS), the method executed by the set of instructions comprising:

negotiating SCS flow parameters;

provisioning a flow using the SCS flow parameters;

determining a Station (STA) associates with an Access Point (AP);

allowing the STA to communicate with the AP using the flow according to the SCS flow parameters;

receiving a request from the STA to associate with a second AP; and

updating the SCS flow parameters based on the association with the second AP.

14 . The non-transitory computer-readable medium of claim 13 , wherein the SCS flow parameters include any one of (i) a delay bound, (ii) a Scheduling Interval (SI), (iii) a Quality of Service (QoS) mapping, or (iv) any combination of (i)-(iii).

15 . The non-transitory computer-readable medium of claim 13 , wherein the SCS flow parameters are for a specific flow supported at the STA or for a class of flows supported by a class of STAs.

16 . The non-transitory computer-readable medium of claim 13 , the method executed by the set of instructions further comprising:

receiving a request for unique SCS parameters from the STA; and

merging the unique SCS parameters with the SCS flow parameters to generate merged SCS flows.

17 . The non-transitory computer-readable medium of claim 16 , the method executed by the set of instructions further comprising:

informing the STA of active SCS sessions by sending the merged SCS flows to the STA.
