摘要： In one embodiment, sessions are synced from an active device to a standby device according to a priority. One or more attributes are determined for a plurality of sessions that need to be synced between an active device and a standby device. The attributes may be used to determine a value of syncing a session. A priority for syncing the sessions based on the attributes is then determined. The sessions are then synced based on the priority. For example, a portion of sessions considered to be of a higher priority may be synced before a portion of sessions considered to be of a lower priority. Because the sessions considered of a higher priority are synced first, if a double failure occurs where the active device fails during the syncing process, at least the higher priority sessions have been synced with the standby device and the standby device can take over these sessions.

摘要： 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.
摘要翻译：在一个实施例中，技术为使用网关的服务提供服务质量（QoS）。这些技术包括从网关处的用户站接收一个或多个控制信令消息。网关处于用户台通过无线网络通信的用户台的信令路径。网关基于一个或多个控制信令消息来确定应用服务的策略。可以基于策略为服务确定QoS参数。例如，为为媒体流创建的会话确定QoS参数。媒体流可以从用户站流向基站到网关，反之亦然。网关可以将QoS参数传送到基站，以使基站在无线网络中预留资源。因此，创建用于用户站的会话并且保留资源以提供用于媒体流的QoS。

摘要： A system for enhancing functionality of a network. In a specific embodiment, the system employs strategic communications between a network controller and a security gateway. The strategic communications occur via a feedback communications channel between the network controller and the security gateway. The feedback communications channel facilitates transferring security information, such as International Mobile Subscriber Identity (IMSI) and other information, between the network controller and the security gateway. The security information may facilitate enabling the SGW to make intelligent decisions as to how to treat a client communications session. In the specific embodiment, the feedback communications channel includes an intervening Authentication, Authorization, and Accounting (AAA) server that is coupled between the UMA and the network controller.
