Patent ID: 8050229

Claim:
An apparatus of mobility management for persistent connections, applicable to a wireless network environment, said wireless network environment having a plurality of mobile nodes located in a plurality of network domains, said apparatus comprising: a plurality of mobility management servers (MMSs), for communicating with said plurality of mobile nodes; and a plurality of Mobility-Aware Socket (MAS) modules for providing persistent connection between mobile nodes, each of said MAS modules belonging to one of said plurality of mobile nodes and comprising a connection splicer for splicing connection between mobile nodes and a network address transformer for network address transformation; wherein when a first mobile node switches from a first network domain to a second network domain, said first mobile node and a target mobile node connected to said first mobile node transmit and receive packets to and from each other directly through the network address transformation of a home address (HA) of said first mobile node and a care-of-address (CoA) obtained from said second network domain in the MAS module of said first mobile node without going through said MMSs, and the MAS module of said first mobile node splices connection to said target mobile node to provide persistent connection between said first and target mobile.
