Patent ID: 8155123

Claim:
A method of packet routing for a localized mobility management (LMM) network, comprising: determining that both a sending end node and a receiving end node are located in the same LMM domain controlled by a local mobility anchor point (LMA), comprising: determining whether a next hop delivery node belongs to the same LMM domain of the sending end node according to a destination address of the received packet sent by the access device attached to the sending end node, wherein the sending end node and the receiving end node are located in the same LMM domain controlled by the LMA if the next hop delivery node belongs to the same LMM domain of the sending end node; enabling a route optimization by sending a redirection notification message containing address information of the sending end node and the receiving end node to an access device attached to the sending end node, when receiving the redirection notification message, the access device attached to the sending end node returns a redirection notification response to the LMA; directly forwarding, by the access device attached to the sending end node, a packet to be sent to the receiving end node to an access device attached to the receiving end node; and forwarding, by the access device attached to the receiving end node, the packet to the receiving end node.
