<p>A method and system for terminal handover in a wireless communication system are disclosed in the present invention. A terminal accesses a packet data network through a packet data network gateway, when the terminal moves between gateways, the target gateway to which the terminal moves allocates a new Routing Identifier (RID) to the terminal, and stores a mapping relationship between the Access Identifier (AID) and the new RID of the terminal; the target gateway or the target mobility management entity (MME) of the terminal initiates a registration update request including the new RID of the terminal to the home Identity Location Register (ILR) of the terminal; after receiving the registration update request, the home ILR of the terminal updates the stored AID-RID mapping information of the terminal according to the new RID of the terminal, and initiates a notification for updating the RID of the terminal to the opposite gateway and/or the opposite MME of the terminal according to the opposite information of the terminal which is received and/or stored locally. With the present invention, the circuitous paths of the data packets can be decreased and the transmission delay and bandwidth waste can be reduced.</p> |
