ABSTRACT:
A method for performing a handover includes: (a) a wireless network controller receiving a handover request message from the mobile station; (b) during an acknowledgement of the handover of the mobile station after receiving the handover request message, the wireless network controller generating a TCP proxy and converting a terminal connection TCP to a split connection TCP; (c) the TCP proxy acknowledging the reception of a packet from the server during the handover on behalf of the mobile station; (d) the TCP proxy storing a packet received from the server in a cache; and (e) upon receiving a handover registration message, the wireless network controller transmitting the packet stored in the cache to the mobile station.
