Claim:
A network device comprising: a processor; and a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to: determine whether a user equipment (UE) is a UE frequently performing state transitions or a UE infrequently performing state transitions; if the UE is determined to be a UE frequently performing state transitions, then transition a state of the UE to a paging channel (PCH) state when no service data sent by the UE in a dedicated channel (DCH) state has been received within a preset counting time of a timer, the transition based on the determination that the UE is a UE frequently performing state transitions; and if the UE is determined to be a UE infrequently performing state transitions, then transition a state of the UE to an idle state when no service data sent by the UE in a dedicated channel (DCH) state has been received within a preset counting time of a timer, the transition based on the determination that the UE is a UE infrequently performing state transitions.
