  • Patent number: 9572084
    Abstract: A method and system for route optimization during switching and an access network element. In a process that a terminal is switched from a source access network element to a target access network element, the target access network element obtains identity information of a correspondent node of the terminal from the terminal, and triggers an access network element of the correspondent node to update a correspondent node mapping relationship. In the present solution, information of a correspondent node is obtained by adding a signaling interaction procedure between the network and the terminal host, so that the information of the correspondent node which is performing data communication is obtained in real time, and a subsequent data stream route optimization process is performed in time, thereby solving the problem of low processing performance and poor real-time performance resulted from an access gateway monitoring, detecting and maintaining correspondent node information.

  • Patent number: 9301229
    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.
