1. A method for switching between different networks is characterized by comprising the following steps:

  • the evolved high-speed packet data eHRPD network decides to switch the terminal in the activated state to a second network;

    the eHRPD network selects target network information of the terminal for switching to the second network by at least one of the following modes;

    the measurement report of the second network reported by the terminal, the second network information acquired from the second network, and the running information of the eHRPD network;

    wherein the target network information comprises at least one of;

    wireless access technology type, frequency information, cell identification information, and indication information returned in case of handover failure;

    the eHRPD network sends the target network information to the terminal through a redirection message or a connection closing message;

    before the eHRPD network selects the target network information according to the measurement report of the second network reported by the terminal, the method further includes;

    the eHRPD network sends a measurement request for instructing the terminal to measure the second network to the terminal, wherein the measurement request comprises at least one of the following information;

    radio access technology type, frequency information, threshold information;

    before the eHRPD network sends the measurement request to the terminal, the method further includes; and

    the eHRPD network determines that the terminal supports the measurement operation among different networks through negotiating parameters.
