Abstract

In one embodiment, techniques provide quality of service (QoS) for services using a gateway. The techniques include receiving one or more control signaling messages from a subscriber station at the gateway. The gateway is in a signaling path for the subscriber station where the subscriber station communicates through a wireless network. The gateway determines a policy to apply for the service based on the one or more control signaling messages. QoS parameters may be determined for the service based on the policy. For example, QoS parameters are determined for a session that is created for a media stream. The media stream may flow from the subscriber station to a base station to the gateway, and vice versa. The gateway may communicate the QoS parameters to the base station to cause the base station to reserve resources in the wireless network. Accordingly, a session for the subscriber station is created and resources are reserved to provide a QoS for a media stream.

Claims

1. A method for providing quality of service (QoS) for services using a network device, the method comprising:

receiving, at the network device, one or more control signaling messages for a service from a subscriber station, the network device being in a signaling path for the subscriber station, the subscriber station communicating through a wireless network, the one or more control signaling messages including a request for the service for the subscriber station;

determining, using the network device, a policy to apply for the service based on receiving the one or more control signaling messages including the request for the service;

determining, using the network device, QoS parameters for the service based on the one or more control signaling messages and the policy; and

causing resources to be reserved in the wireless network for a media stream to provide the service to the subscriber station, the reserved resources providing a QoS for the media stream that is determined based on the determined QoS parameters.

2. The method of claim 1, wherein causing resources to be reserved comprises causing a base station associated with the subscriber station to reserve the resources in the wireless network.

3. The method of claim 1, further comprising sending classification information to the subscriber station, the classifiers allowing the subscriber station to identify the media stream to allow the QoS to be applied.

4. The method of claim 1, further comprising:

determining, at the network device, when a session end control signaling message for ending the session is received; and

causing the reserved resources to be released.

5. The method of claim 1, further comprising:

receiving packets from the media stream, the packets including a classification information; and

applying the QoS for the packets.

6. The method of claim 1, further comprising:

establishing a new session based on the one or more control signaling messages;

associating the QoS parameters with the new session.

7. The method of claim 1, further comprising communicating with a home network associated with the subscriber station to determine the policy associated with the subscriber station.

8. The method of claim 1, wherein the QoS is provided without using an IMS infrastructure.

9. The method of claim 1, wherein the QoS is provided without contacting an IMS infrastructure.

10. The method of claim 1, wherein the network device and the base station share a security association.

11. A network device configured to provide quality of service (QoS) for services, the device comprising:

a proxy configured to receive one or more control signaling messages for a service from a subscriber station, the proxy being in a signaling path for the subscriber station, the subscriber station communicating through a wireless network, the one or more control signaling messages including a request for the service for the subscriber station;

one or more computer processors; and

a memory containing instructions that, when executed by the one or more processors, cause the one or more processors to perform a set of steps comprising;

determining a policy to apply for the service based on receiving the one or more control signaling messages including the request for the service;

determining, using the one or more computer processors, QoS parameters for the service based on the one or more control signaling messages and the policy; and

causing resources to be reserved in the wireless network for a media stream to provide the service to the subscriber station, the reserved resources providing a QoS for the media stream that is determined based on the determined QoS parameters.

12. The network device of claim 11, wherein the instructions cause the one or more processors to cause a base station associated with the subscriber station to reserve the resources in the wireless network.

13. The network device of claim 11, wherein the proxy is configured to send classification information to the subscriber station, the classifiers allowing the subscriber station to identify the media stream to allow the QoS to be applied.

14. The network device of claim 11, wherein the proxy is configured to:

determine when a session end control signaling message for ending the session is received; and

cause the reserved resources to be released.

15. The network device of claim 11, wherein the instructions cause the one or more processors to perform further steps comprising:

receiving packets from the media stream, the packets including a classification information; and

applying the QoS for the packets.

16. The network device of claim 11, wherein the instructions cause the one or more processors to perform further steps comprising:

establishing a new session based on the one or more control signaling messages;

associating the QoS parameters with the new session.

17. The network device of claim 11, wherein the instructions cause the one or more processors to perform a further step comprising communicating with a home network associated with the subscriber station to determine the policy associated with the subscriber station.

18. The network device of claim 11, wherein the QoS is provided without using an IMS infrastructure.

19. The network device of claim 11, wherein the QoS is provided without contacting an IMS infrastructure.

20. The network device of claim 11, wherein the network device and the base station share a security association.

21. An apparatus configured to provide quality of service (QoS) for services using a network device, the apparatus comprising:

means for receiving, at the network device, one or more control signaling messages for a service from a subscriber station, the network device being in a signaling path for the subscriber station, the subscriber station communicating through a wireless network, the one or more control signaling messages including a request for the service for the subscriber station;

means for determining, using the network device, a policy to apply for the service based on receiving the one or more control signaling messages including the request for the service;

means for determining, using the network device, QoS parameters for the service based on the one or more control signaling messages and the policy; and

means for causing resources to be reserved in the wireless network for a media stream to provide the service to the subscriber station, the reserved resources providing a QoS for the media stream that is determined based on the determined QoS parameters.
