Abstract

The embodiment of the invention discloses a method for optimizing cell reselection, which comprises the following steps that: an RNC receives a cell update message CELL UPDATE sent by UE, wherein thecell update message comprises a cell for representing cell information; and the RNC judges whether a cell update response message transmitted to the UE carries reconfiguration information according tothe cell, and if so, the cell update response message comprising the reconfiguration information is sent so as to reconfigure the UE according to the reconfiguration information, otherwise, the cellupdate response message does not comprise the reconfiguration information. The embodiment of the invention also provides a device for optimizing the cell reselection. Through the embodiment of the invention, the RNC can determine the current configuration information of the UE and accurately write a cell update confirmation message after the UE performs a plurality of times of cell update and theRNC performs reconfiguration on a logic channel or a transmission channel or a physical channel of the UE.

Description

technical field [0001] The present invention relates to the field of mobile communications, and in particular, to a cell reselection optimization method and device. Background technique [0002] 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) Release 7 (3GPP Release 7, 3rd Generation Partnership Project R7 version), after the introduction of EFACH (Enhanced CELL_FACH, enhanced FACH), the UE (User Equipment, The peak rate of the user equipment (or also referred to as the mobile terminal) reduces the state switching delay and reduces the power consumption of the UE in the CELL_FACH state. According to the latest R7 and R8 protocols, when the UE performs multiple cell reselections from the FACH to the EFACH cell, the RNC cannot determine whether the UE is currently in the FACH or EFACH configuration, resulting in the RNC (RadioNetwork Controller, radio network controller) erroneously Fill in the cell update confirmation message. [0003] During t...
