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： In one embodiment, sessions are synced from an active device to a standby device according to a priority. One or more attributes are determined for a plurality of sessions that need to be synced between an active device and a standby device. The attributes may be used to determine a value of syncing a session. A priority for syncing the sessions based on the attributes is then determined. The sessions are then synced based on the priority. For example, a portion of sessions considered to be of a higher priority may be synced before a portion of sessions considered to be of a lower priority. Because the sessions considered of a higher priority are synced first, if a double failure occurs where the active device fails during the syncing process, at least the higher priority sessions have been synced with the standby device and the standby device can take over these sessions.
摘要翻译：在一个实施例中，会话根据优先级从活动设备同步到备用设备。确定需要在有源设备和备用设备之间同步的多个会话的一个或多个属性。属性可用于确定同步会话的值。然后确定基于属性同步会话的优先级。然后根据优先级同步会话。例如，被认为具有较高优先级的一部分会话可以在被认为是较低优先级的一部分会话之前被同步。由于考虑到较高优先级的会话首先同步，如果活动设备在同步过程中发生故障，则至少具有较高优先级的会话已与备用设备同步，备用设备可以接管这些会话。

摘要： Techniques for providing wireless services to mobile subscribers using existing broadband network infrastructures are described herein. In one embodiment, in response to a request received at a gateway device from a mobile subscriber over a radio access network (RAN) for accessing a service provider network, the gateway device authenticates the mobile subscriber for accessing the RAN, where the gateway device interfaces the RAN and the existing broadband network. Upon successfully authenticating the mobile subscriber for accessing RAN, the gateway device accesses a network service provider over the existing network to acquire a network address on behalf of the mobile subscriber optionally using at least a portion of credentials derived from the authentication, where the network address allows the mobile subscriber to access the service provider network. Other methods and apparatuses are also described.

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： 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.
