摘要： In one embodiment, techniques for authorizing a mobile device are provided. A registration request is received for the mobile device. The registration request may include location identifier information. For example, a cell ID may be provided. Static location information is then determined based on the location identifier information. The static location information may be spatial coordinates. The registration request is then authorized based on the static location information. For example, a cell ID may be received and then spatial coordinates may be determined based on the cell ID. The registration request is then authorized based on the spatial coordinates. A response to the registration request is then sent.

摘要： Techniques and systems for server farm load balancing and resource allocation are disclosed. In one embodiment, a method of load balancing can include: arranging servers into service groups; receiving an access request with information related to a differentiation between the service groups; selecting one of the service groups based on a mapping comparison to the information; and selecting one of the servers within the selected service group based on a hardware utilization comparison. The servers can include GPRS (General Packet Radio Service) Gateway Support Node (GGSN) or Remote Authentication Dial In User Service (RADIUS) servers, for example. The information can include an Access Point Name (APN) or Calling Station ID, for example.

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： 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： Systems and method are provided that allow an application layer client in a mobile device to manage multiple interfaces in a communication network. The multiple interfaces can include WiFi, cellular, Femto, WiMAX, Bluetooth, infrared, Ethernet, and other types of interfaces for communication in a network. The client on the mobile device can use intelligence and rules to determine how and when request fragments are communicated over the various interfaces available to the client. The intelligence can include parameters such as performance information for a particular interface and subscriber preferences. Based on this information the client can decide to use a combination of the interfaces to obtain multimedia content and render the content for display on the mobile device. By using a combination of interfaces and tracking the advantages and disadvantages of each interface, the client can make intelligent decisions in providing multimedia content to the user.

摘要： Network operators have deployed multiple network devices to provide stable data services amid a rapid increase in data traffic. One way to balance data load among the multiple network devices is by distributing the user equipments across the multiple network devices using an explicit detach with reattach required procedure. However, the explicit detach with reattach required procedure can disrupt on-going data services of user equipments. This disclosure provides systems and methods of an enhanced explicit detach with reattach required procedure that reduces disruption of on-going data services due to the explicit detach with reattach required procedure.

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。 使用确定的信息生成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： 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.
