状態転送のためにモバイルノードを利用するための方法および装置

Japanese Patent JP2009509463

A

Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a end node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff or the use of a core network node to support state transfer. As part of a handoff state information is obtained by an end node from the current access node in encrypted form and then communicated to the new access node to which the handoff operation is to be completed. The new access node, e.g., base station decrypts the state information and then uses it to support communications with the end node. While the information is communicated to and from the end node over wireless links, since it is encrypted by the first access node it is secure and can be trusted by the receiving, e.g., target, access node.
