Patent ID: 8316153

Claim:
A method for notifying proxy update in a Wireless Mesh Network (WMN), comprising: constructing a proxy update add message, wherein the proxy update add message comprises an address of a terminal, an address of a current proxy node after terminal switching, and a destination node address, wherein the destination node address is an address of an original proxy node, which is the proxy node before terminal switching; sending the proxy update add message to the original proxy node, wherein the proxy update add message is for updating proxy information of the terminal in a proxy information table of the original proxy node to be the address of the current proxy node; receiving the proxy update add message sent by the current proxy node, and searching a local proxy information table for acquiring the address of the original proxy node of the terminal according to the address of the terminal carried in the proxy update add message; wherein the proxy update add message sent by the current proxy node further comprises a distribution identifier configured to identify whether the proxy update add message is sent to the original proxy node or not; and after receiving the proxy update add message sent by the current proxy node, according to the distribution identifier, the proxy update add message is forwarded to a next hop when the proxy update add message has been sent to the original proxy node; and when the proxy update add message has not been sent to the original proxy node, the proxy update add message is constructed and the distribution identifier is modified to identify that the proxy update add message has been sent to the original proxy node.
