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.
