Abstract: A method and system for terminal switching in a wireless communication system are disclosed. A terminal accesses a packet data network through a packet data network gateway, when the terminal switches between gateways, the target gateway to which the terminal switches 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 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.
