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. The reauthentication information includes one or more keys and/or counters, such as an authorization key, an encryption key, and a master key, which is/are predetermined by the AAA server.

摘要： An Unlicensed Mobile Access (UMA) network architecture. In a specific embodiment, the network architecture includes a mobile station and an access point in communication with the mobile station. A UMA Controller (UNC) communicates with the access point. A Service GateWay (SGW) communicates with the UMA controller. The SGW includes functionality to route user-plane packets in the UMA. In a more specific embodiment, the functionality includes UNC user-plane functionality offloaded from the UNC to the SGW; Serving GPRS Support Node (SGSN) user-plane functionality; access-authentication functionality sufficient to enable the SGW to enable the SGW to bypass a legacy SGSN control plane; and/or Radio Network Controller (RNC) user-plane functionality sufficient to enable communications between the SGW and the RNC.

摘要： In one embodiment, a security gateway receives an IPSec Initiation (IPSec INIT) request from a client. The security gateway may communicate with a AAA server to authenticate the client. After authentication, the security gateway intercepts a URR Discovery request from the client. The security gateway determines registration information for a response to the registration request. The registration information may be information on where the client can locate a D-GANC. A response is generated using the determined information and sent to the client. The response to the discovery request is performed without communicating with a P-GANC. Accordingly, a security gateway is used to authenticate the client and also to respond to the discovery request. This does not require that a P-GANC function be deployed in a network. Thus, cost and processing power may be saved.
摘要翻译：在一个实施例中，安全网关从客户端接收IPSec启动（IPSec INIT）请求。安全网关可以与AAA服务器进行通信，以验证客户端。认证后，安全网关从客户端拦截URR发现请求。安全网关确定用于对注册请求的响应的注册信息。注册信息可以是客户端可以在哪里定位D-GANC的信息。使用确定的信息产生响应并发送给客户端。在不与P-GANC通信的情况下执行对发现请求的响应。因此，安全网关用于认证客户端并且还响应于发现请求。这不需要在网络中部署P-GANC功能。因此，可以节省成本和处理能力。

摘要： Systems and methods for modifying a media protocol based on subscriber and network performance information is disclosed. Media protocols such as adaptive bitrate protocol can adjust bit rates based on conditions perceived at the mobile device and with a goal of obtaining the highest bit rate possible. The media protocols residing on the mobile device do not have access to network performance information that can change rapidly and impact the experience at the mobile device. For example, congestion, radio air link interference, handoffs, and quality of service parameters can all impact the experience a user has when accessing media files from a mobile device. The requests made by a mobile device can be modified to take into account these factors to enhance the user experience.
摘要翻译：公开了基于用户和网络性能信息修改媒体协议的系统和方法。诸如自适应比特率协议的媒体协议可以基于在移动设备处感知到的条件来调整比特率，并且可以获得可能的最高比特率的目的。驻留在移动设备上的媒体协议不能访问可以快速改变并影响移动设备体验的网络性能信息。例如，拥塞，无线电空中链路干扰，切换和服务质量参数都可能影响用户在从移动设备访问媒体文件时所经历的体验。可以修改由移动设备发出的请求以考虑到这些因素以增强用户体验。

摘要： An apparatus for charging in a network environment is provided that includes an access gateway encapsulation/decapsulation element operable to establish one or more packet data protocol (PDP) links on behalf of an end user and to perform encapsulation and decapsulation operations for one or more of the links associated with the end user. The access gateway encapsulation/decapsulation element is further operable to interface with a client services packet gateway (CSPG) that is operable to provide enhanced packet processing for the end user for requested information. The apparatus also includes an access gateway policy element operable to interface with the CSPG. The access gateway encapsulation/decapsulation element and the access gateway policy element cooperate to use one or more inter-module headers in order to coordinate the enhanced packet processing for one or more communication flows associated with the end user.
