Method, system and device for realizing state transition

Abstract

The invention discloses a method, a system and a device for realizing state transition and aims to solve the conventional problem that normal communication between a base station and a terminal is not available due to state comprehension difference during state transition. The method comprises the following steps that: a radio network controller (RNC) transmits reconfiguration information to the terminal, wherein the reconfiguration information comprises first activation moment information; the RNC transmits a radio link activating command to the base station, wherein and the radio link activating command comprises second activation moment information; and the activation moment of the first activation moment information is the same as that of the second activation moment information; and the RNC indicates the terminal and the base station to determine the transition state of the terminal according to the first activation moment and the second activation moment respectively. New fields are added in a control signaling of a wireless link, so that the state transition control of the base station and the terminal is realized and the state comprehension of the terminal is accordant with that of the base station. Therefore, the base station can normally communicate with the terminal so that a smooth state transition process is realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and device for realizing enhanced CELL-FACH state and CELL-DCH state transfer. Background technique [0002] In the traditional CELL-FACH state, the terminal sends uplink data through the random access channel (Random Access Channel, RACH), receives downlink data through the forward access channel (Forward Access Channel, FACH), all state control and data The transmission is all completed through interaction with a radio network controller (Radio Network Controller, RNC). [0003] However, in the enhanced CELL-FACH state, the base station needs to calculate the scheduling time for terminal data and process the information fed back by the terminal. Therefore, the base station needs to maintain the context information of the terminal in the enhanced CELL-FACH state. And in the prior art, the configuration parameters used when in the CELL-DCH state and the e...
