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 apparatus for providing mobility in an Internet protocol (IP) network environment is provided that includes a cell site element operable to receive an address resolution protocol (ARP) signal from a base station. The ARP signal is associated with a selected mobile station that can roam between networks. In response to the signal, the cell site element evaluates a table that identifies a plurality of mobile stations and if the selected mobile station is not present in the table, then a mobility registration request is generated and communicated to a next destination.

摘要： Facilitating a graceful restart operation includes initiating the graceful restart operation at a gateway of an access service network. A graceful restart request is sent to a helper device. The graceful restart request requests that the helper device recognize the gateway as adjacent during a specified grace period. If the helper device supports the graceful restart operation, information is received from the helper device in response to the graceful restart request. The graceful restart operation is terminated.

摘要： Particular embodiments provide an access gateway that facilitates communication between a plurality of access technologies. The access gateway facilitates data communication with an access terminal through a bearer path. A radio resource manager is configured to provide radio resource management functions for the communications. The radio resource manager is decoupled from the bearer path and provides control of radio transmission characteristics for the bearer path to the gateway. Because the radio resource manager is not in the bearer path, the access gateway may be access technology agnostic. Thus, the access gateway does not need to have access-specific modules based on the radio technology for each bearer path.
摘要翻译：具体实施例提供了便于多个接入技术之间的通信的接入网关。接入网关便于通过承载路径与接入终端的数据通信。无线资源管理器被配置为为通信提供无线电资源管理功能。无线电资源管理器与载体路径解耦，并提供对网关承载路径的无线电传输特性的控制。由于无线电资源管理器不在承载路径中，因此接入网关可能与无线技术无关。因此，接入网关不需要基于用于每个承载路径的无线电技术的访问专用模块。

摘要： Particular embodiments provide an optimal allocation of a bearer manager or home agent. In one embodiment, a message is received from a mobile node requesting access to a visiting network that is different from a home network for the mobile node. An authentication request is sent to the home network requesting authentication for access. The authentication request indicates that a home agent has not been assigned. The home AAA server then sends a response that indicates the visiting AAA server can assign a home agent for the mobile node. The visiting AAA server then assigns a home agent that is optimally determined. The visiting home agent is different from a home agent that is found in the mobile node's home network. When a registration request is received, an IP gateway may send the registration request to the visiting home agent, which may not be sent back to the home network.
摘要翻译：特定实施例提供承载管理器或归属代理的最佳分配。在一个实施例中，从移动节点接收请求访问不同于移动节点的归属网络的访问网络的消息。认证请求被发送到家庭网络，请求认证进行访问。认证请求表示没有分配归属代理。然后，归属AAA服务器发送响应，其指示访问AAA服务器可以为移动节点分配归属代理。然后，访问的AAA服务器分配最佳确定的归属代理。访问归属代理与在移动节点的家庭网络中找到的归属代理不同。当接收到注册请求时，IP网关可以将该注册请求发送到访问归属代理，该归属代理可能不被发送回家庭网络。

摘要： Providing a multicast service to a mobile node includes receiving a first request to join a multicast group from a first cell site. The first request requests that a first mobile node be permitted to join the multicast group. A first multicast source operable to provide content to the first mobile node is identified. The multicast group and the first multicast source are associated to yield a first group-source combination. A first key is assigned to the first group-source combination, and the first key is provided to the first cell site.

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.
