  • Publication number: 20120231759
    Abstract: A redirection method, a redirection device, and a communication system in the field of communication technology are provided. The redirection method includes the following steps: A femto access point (FAP) receives a message, in which the message contains information of a service required by a terminal. After the FAP determines that it does not support the service, the FAP acquires information of base stations supporting the service. The FAP sends the information of the base stations supporting the service to the terminal, so as to enable the terminal to determine a target base station according to the information of the base stations supporting the service. Therefore, the terminal is redirected to the target base station supporting the service required by the terminal, and efficiency of implementing the required service by the terminal is increased.

  • Publication number: 20120182970
    Abstract: A method, a system and a device for network handover are provided, which are applied to the field of communications technologies. The method includes the following steps that: a terminal first obtains information of a handover manner of handover from a virtual base station to a target base station, and then sends a corresponding message to the virtual base station according to the information of the handover manner, so as to perform network handover, so that in a procedure that the terminal is handed over from a non-WiMAX network to a WiMAX network, the terminal may be directly handed over according to the handover manner supported by the virtual base station. Compared with the conventional art in which handover manners require handover attempts, the adoption of the method for network handover reduces handover time and increases network handover efficiency.

  • Publication number: 20120157102
    Abstract: The present invention discloses a handover method and a handover device. An attachment point is handed over from a service station of a first access network to a handover server of the first access network before a UE hands over from the first access network to a second access network. The handover server of the first access network is interacted with through the tunnel to enter an idle mode of the first access network after completing network access in the second access network. Attachment to a destination station of the first access network is performed to quit the idle mode and re-access the first access network when the UE hands over back to the first access network.
