  • Patent number: 9860831
    Abstract: The present invention provides a terminal and method for an idle handoff based on a High Rate Packet Data (HRPD) system. The method includes, when the terminal switches from the HRPD system to a non-HRPD radio access technology system, an HRPD protocol stack of the terminal migrating from a non-tunnel state to a tunnel state. When the terminal is in a handoff area, and performs the idle handoff from the HRPD system to the non-HRPD radio access technology system, the terminal after the handoff is in the tunnel state, and the HRPD session information of the terminal is reserved. Thus, when the terminal switches back to the HRPD system, it is not necessary to perform the HRPD session negotiation again, thereby effectively avoiding the waste of air interface resources and system processing capabilities, and improving efficiency of interconnection and intercommunication between the HRPD system and other radio access technology system.
