摘要： User equipments can download a video file by instantiating multiple video requests, each request specifying different parts of the video file. If each video request initiates a separate transmission control protocol (TCP) session, which is the case with an hypertext transfer protocol (HTTP) partial get request, then a network device in a communications network would be oblivious of contextual information, which indicates that the TCP sessions download different portions of the same video file. This disclosure provides systems and methods for correlating multiple TCP sessions so that a network device in a communications network can be aware of the contextual information.
摘要翻译：用户设备可以通过实例化多个视频请求来下载视频文件，每个请求指定视频文件的不同部分。如果每个视频请求启动单独的传输控制协议（TCP）会话，这是超文本传输协议（HTTP）部分获取请求的情况，则通信网络中的网络设备将不会上下文信息，这表示 TCP会话下载同一视频文件的不同部分。本公开提供了用于关联多个TCP会话的系统和方法，使得通信网络中的网络设备可以知道上下文信息。

摘要： A system for efficiently reauthenticating a client of a network. In a specific embodiment, the system includes an authentication server and a Security GateWay (SGW) in communication with the client. The SGW includes reauthentication information associated with the client. In a more specific embodiment, the authentication server includes an Authentication, Authorization, and Accounting (AAA) server. The SGW further includes one or more routines for employing the reauthentication information to reauthenticate the client. The AAA server performs initial authentication of the client to enable client access to the network, which yields the reauthentication information.

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.

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.
