  • Patent number: 8244242
    Abstract: A method for storing an address of a network anchor point to a network server is provided The provided method includes the following steps: a terminal initiates an attach request or a bearer establishment request, and a network selects a network anchor point; and when the network anchor point assigns a first bearer context to the terminal, or a first connection is established between the network anchor point and the terminal, the network registers an address of the network anchor point to a network server. A method for deleting an address of a network anchor point from a network server is also provided, which includes the following steps: when a terminal or an entity in a network initiates a delete bearer request, the network instructs a network server to delete an address of a network anchor point that has been registered to the network server if the network anchor point no longer serves the terminal; and the network server deregisters the address of the network anchor point.

  • Publication number: 20120106456
    Abstract: A method, an apparatus, and a system for routing user plane data in a mobile network are disclosed in the embodiments of the present invention, relate to the field of communications, and solve the problem that transmission delay of packet service data is relatively great in the prior art. The method for routing user plane data in the mobile network includes that: an access network bearer and a PDN gateway bearer of a user equipment are directly interconnected through a tunnel established between an access network and a PDN gateway; and data between a Home NodeB, a Home NodeB Gateway or a macro network access network and the PDN gateway is directly routed through the tunnel. The method, the apparatus, and the system can be applied to a mobile communication system.

  • Publication number: 20100232393
    Abstract: A method, device and system for implementing optimized inter-RAT handover are disclosed. When a user equipment or a source network prepares for a handover to a target network, a corresponding target network ID is obtained from a configured mapping between cell IDs and target IDs according to a received cell ID, target network bearers are established following identification of an access node of the target network, and the user equipment is connected to the target network after handover preparation is complete. With the present invention, when a user equipment is handed-over from a source network to a target network, service continuity can be maintained with an enhanced quality of user experience.
