Patent ID: 7697930

Claim:
A method for mobility management in wireless networks, wherein said wireless networks comprise a mobility management server (MMS) device, one mobile device in a first network domain having connection to one corresponding node, and handover of said mobile device to a second network domain comprises the steps of: (a) said mobile device selecting one or more access point (AP) candidates which said mobile device intends to connect to, wherein a network domain corresponding to each said AP candidate is a candidate network domain; (b) said mobile device providing said MMS device with the information of said AP candidates, obtaining network configurations of the candidate network domains from said MMS device, and requesting said MMS device to initiate a packet relay service according to the network configurations; (c) said mobile device informing said corresponding node of temporarily redirecting packets for said mobile device to said MMS device; (d) said MMS device relaying the packets for said mobile device by relaying the packets to two or more candidate IP addresses that said mobile device may use including IP address in said first network domain, and IP addresses in all candidate network domains; (e) said mobile device connecting to a chosen AP of said AP candidates, and establishing a network connection through the chosen AP; and (f) said mobile device updating registration information at a communication server of said chosen AP, and informing said corresponding node of sending packets to said mobile device, wherein, there is no sequential dependency between the two actions of said updating registration information at the communication server and said informing the corresponding node to send packets to said mobile device.
