METHOD FOR TRANSITIONING OF STATE MACHINES AFTER RADIO ACCESS NETWORK IS RESELECTED AND TERMINAL

摘要

The present invention relates to the communication field and discloses a method for transitioning of a state machine after a radio access network (RAN) is reselected and a terminal. With the present invention, after a mobile terminal reselects from a high rate packet data (HRPD) network to a long term evolution (LTE) network, related protocols can know the rcsclcction, thus ensuring that the mobile terminal performs normal actions subsequently. The method includes: generating first information when a mobile terminal reselects from an HRPD network to an LTE network; after receiving the first information, setting, by the Signaling Adaptation Protocol (SAP) of the HRPD module air interface protocol, the TunnelModeEnabled parameter to a first identifier, so that air interface related sub-protocols of an HRPD module know that the mobile terminal has reselected to the LTE network. The present invention is applicable to a scenario in which the terminal reselects from the HRPD network to the LTE network.
