摘要： A method includes a network originating a QoS reservation message and communicating the network-originated QoS message through a radio access network (RAN) from an access gateway (AGW) to an access terminal (AT). The network-originated reservation message does not cause any network resource reservation by itself, but causes the AT to initiate a network resource reservation according to one or more parameters in the network-originated QoS reservation message. Accordingly, an existing network infrastructure supporting AT-originated QoS reservation may support network-originated QoS reservation (or proxied QoS) without any updates to an access-network infrastructure, such as the RAN. The method includes, in response to the network-initiated QoS reservation message, communicating a reservation confirmation through the RAN from the AT to the AGW. The reservation confirmation whether that the QoS reservation was successful.

摘要： A mechanism that provides for communication of heartbeat signals from servers (call agents) to clients (gateways) in a packet telephony network environment. Clients listen for receipt of multicast heartbeats from any of the servers that may be part of a multicast group. A client assigned to a particular server for control messaging, upon failure to receive a response to a message sent to the assigned server and failure to receive a heartbeat from the assigned server, may select a second server from among the servers and re-send the message to the second server. Without receipt of heartbeat signals, the client defaults to a normal retry behavior for re-sending the message first to the assigned server a number of times before attempting to re-send the message to the second server. With receipt of the heartbeat from the second server, the client adopts an aggressive retry behavior by re-sending the message to the assigned server a lesser number of retries before attempting to re-send the message to the second server. The clients use the multicast heartbeats as a hint, allowing them to switch to the more aggressive retry behavior and consequently reduce the time to re-associate with a new server and re-establish a new security association (if IPsec is used), resulting in a drastic reduction in service delay due to server failures.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
