Abstract: In one embodiment, a network device receives an Internet protocol (IP) registration request, such as a mobile IP registration request, from an access terminal. The network device may be a home agent that is configured to register the access terminal for IP services at the network layer. In addition to registering the access terminal at the network layer, the network device may facilitate registration at another layer, such as the application layer. In one example, registration information for the access terminal for an application layer registration, such as information needed to register for a session initiation protocol (SIP) services, is determined. The network device then facilitates registration at the application layer automatically using the registration information.

Abstract: A mechanism provides for communication of “keep-alive” messages from clients to servers in a packet telephony network environment. The servers may be call agents and the clients may be gateways or MGCP-controlled IP phones. A client (e.g., gateway) registers a virtual endpoint. Upon a period of inactivity in which the client does not receive any commands or acknowledgments from an assigned server (e.g., call agent), the client starts to send keep-alive messages periodically to the server. The keep-alive message may include an endpoint identifier that identifies the registered virtual endpoint. If the server fails to respond to the keep-alive messages after a period of time, the client initiates a fallback mechanism from a first call control protocol (e.g., MGCP) to a second call control protocol (e.g., H.323 or SIP), to provide call control handling using a default application. The keep-alive messages may be sent to other servers among the plural servers that are configured to operate with the client before determining whether to initiate the fallback mechanism. During the fallback state, the keep-alive message may be sent periodically until a response is received from the server. Communications with the assigned server may be reestablished thereupon based on the first call control protocol.

Abstract translation: 一种机制提供了在分组电话网络环境中从客户机到服务器的“保持活动”消息的通信。 服务器可以是呼叫代理，并且客户端可以是网关或MGCP控制的IP电话。 客户端（例如，网关）注册虚拟端点。 在客户端没有从分配的服务器（例如，呼叫代理）接收到任何命令或确认的不活动时段时，客户端开始向服务器周期性地发送保持活动消息。 保持活动消息可以包括标识注册的虚拟端点的端点标识符。 如果服务器在一段时间后无法响应保持活动消息，则客户端发起从第一呼叫控制协议（例如，MGCP）到第二呼叫控制协议（例如，H.323或SIP）的回退机制， ，使用默认应用程序提供呼叫控制处理。 可以在确定是否启动后备机制之前将保持活动消息发送到被配置为与客户端一起操作的多个服务器中的其他服务器。 在回退状态期间，可以周期性地发送保持活动消息，直到从服务器接收到响应。 基于第一呼叫控制协议，可以与分配的服务器的通信重新建立。

Abstract: A method and apparatus of communication processing at a client (e.g., media gateway) connected to a server (e.g., media gateway controller) includes collecting events in a quarantine buffer. The contents of the buffer are examined to determine whether the collected events include one or more synchronizing events. An instruction signal sent to the client from the server includes information defining one or more events as a synchronizing event. If one or more synchronizing events is present, the collected events are processed from the buffer relative to the one or more synchronizing events. The processing may include processing the collected events beginning after the most recent or second most recent synchronizing event. The collected events that occurred up to the most recent or second most recent synchronizing event may be moved to a synchronized event list. The synchronized event list may be reported to the server or discarded.

Abstract: In one embodiment, a method includes receiving, at a visited network node, policy for a roaming terminal from a home network of the roaming terminal. The policy is associated with a home Internet Protocol (IP) address of the roaming terminal. The visited network node applies the policy in the visited network to data packets that include the home IP address. Applying the policy to a data packet encompasses either enforcing the policy at the node that applies the policy or sending data that indicates the policy to a different node that applies the policy based on the data sent, or both.

Abstract: This disclosure relates to a system and method for offloading selected data traffic in logical tunnels to the Internet. The offloading provides another data path for selected data traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. This disclosure provides systems and methods for offloading data to the Internet at a router to relieve congestion on the mobile operator's network.

Abstract: The present invention provides a method for performing automatic discovery of controlling policy enforcement points in a policy push computer network. The method involves a policy decision point sending a discover message toward an end point on a computer network; receiving a response from a policy enforcement point; reading a name and address from the received response; and sending a policy decision message to the name and address read from the response. The policy decision message is characterized by content suitable for being installed for a policy enforcement point. In an embodiment, the discover message sent includes a resource reservation protocol and a new policy enforcement point discover object. In another embodiment, the discover message sent causes the policy enforcement point to process the discover message. The policy decision point can receive notification that installation of the policy decision for the policy enforcement point failed.

Abstract: In one embodiment, a method includes receiving packet flow optimization (PFO) configuration data that associates each rule name of multiple PFO rule names with a corresponding method for processing a data packet in a communications network based on data in a payload of a layer 3 protocol of the data packet. A first policy message is received from a policy management process in the communications network. The first policy message includes rule data that indicates a signaled rule name associated with a particular network address in the communications network. In response to receiving the first policy message, a data packet of the particular network address is processed according to a particular method associated with a particular rule name selected based on the signaled rule name. As a result, a PFO policy is controlled from the policy management process.

Abstract: A system for enforcing policy in a communication network includes a policy server which is operable to receive a request to invoke an application, receive a policy profile for a network user, and decide a proper allocation of network users based on the policy profile, the application, and available network resources. The policy server is further operable to communicate with a non-SIP application. The system also includes a network resource manager operably associated with the policy server and operable to monitor available network in the resources in the communication network. In addition, the network resource manager is functional to allocate network resource amongst a plurality of network users. The system also contains an application control point which is operably associated with the policy server and operable to communicate with a SIP application. The system is operable to use policy peering between the home and visited network to enable user-specific policies to be enforced while roaming.
