    摘要： Methods and apparatus for efficient routing in communication networks. In an aspect, a method is provided for traffic routing between first and second nodes in a communication network. The method includes detecting traffic transmitted between the first and second nodes, transmitting a request to a mobility agent associated with the first node to request authorization for a route optimization between the first and second nodes, receiving a response that authorizes the route optimization, and establishing an optimized route. In an aspect, an apparatus includes detector logic for detecting traffic transmitted between the first and second nodes, transmitting logic for transmitting a request to a mobility agent associated with the first node to request authorization for a route optimization between the first and second nodes, receiving logic for receiving a response that authorizes the route optimization, and connection logic for establishing an optimized route.

    摘要： A method is provided for securing a PMIP tunnel between a serving gateway and a new access node through which an access terminal communicates. A PMIP key hierarchy unique to each access terminal is maintained by the gateway. The gateway uses a first node key to secure PMIP tunnels when authentication of the access terminal has been performed. A PMIP key is generated based on the first node key and the PMIP key is sent to the new access node to assist in establishing and securing a PMIP tunnel between the gateway and the new access node. Otherwise, when authentication of the access terminal has not been performed, the gateway generates a second node key and sends it to an intermediary network node which then generates and sends a PMIP key to the new access node. This second key is then used to secure the PMIP tunnel.

    摘要： In a communications system where a mobile node seeks to establish contact with a server node within or outside the home network of the mobile node by first providing the general location information and the server type of the server node to a DHCP (Dynamic Host Configuration Protocol) server. The DHCP server then matches the provided information with its record in storage to arrive at an IP (Internet Protocol) address of the sought server node. The DHCP server then sends the IP address to the mobile node, thereby allowing the mobile node to directly access the server node.
