STATE TRANSITION METHOD AND SYSTEM, BASE STATION AND USER EQUIPMENT

摘要

Provided are a state transition method and system, a base station and user equipment. The method comprises: when UE which supports seamless state transition is in a CELL_FACH state and if the condition of starting up or restarting a first timer is met, a base station starting up or restarting the first timer; when the first timer operates for a first preset duration after being started up or restarted, the base station determining that the first timer is cut off; and according to the cut-off time of the first timer, the base station determining the transition time for the UE to transition to a CELL_PCH state, and determining that the UE transitions to the transition CELL_PCH state in the transition time. The technical solution in the embodiments of the present invention can effectively save the signalling load of a network, and save network resources.
