摘要： In one embodiment, a first access request is received from a mobile device. The access request may be received through a first access medium for a virtual access point name (APN). A session is created with a service using a first real access point name (APN) for the mobile device. A second access request is received through a second type of access medium. The request may be received through a second virtual APN. A session is determined that is active for the mobile device through the first access medium and the second access request is assigned the first real APN even though the request is received through a second access medium. The continuity of the connection may then be maintained because the first real APN is still being used. In this case, a handoff of the connection from the first access network to the second access network is performed while the connection to the service is maintained through the first real APN.

摘要： In one embodiment, a load balancer receives a message from a tunnel termination gateway (TTG) associated with a mobile device. The load balancer may receive messages from a plurality of TTGs. A gateway node in a plurality of gateway nodes in which to send the message is determined. The load balancer then assigns a NSAPI for use by the gateway node. For example, the NSAPI may be associated with a tunnel that is generated between the TTG and GGSN. The load balancer ensures that the assigned NSAPI is not currently in use at the gateway node. Thus, no overlapping of NSAPIs may occur even though the load balancer is processing messages from multiple TTGs for multiple gateway nodes.

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, 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： Network operators are striving to find ways to provide stable video services amid a rapid increase in video data traffic. In order to provide stable video services with constrained network resources, network operators attempted to deploy multiple communication networks in parallel. However, network operators failed to effectively balance data traffic across parallel communication networks. This disclosure provides systems and methods for effectively balancing data traffic across parallel communication networks.
