A method, system and device for controlling user equipment to switch between cells

Abstract

The invention discloses a method for controlling cell switching of user equipment (UE). The method comprises when network receives a cell updating message from user equipment (UE), if the network havealready transmitted switching command to the UE and have not received a switching command completion message transmitted from the UE, the network sets the value of the radio resource control transaction identity in the switching command as the value of the radio resource control transaction identity in the feedback message to be transmitted to the UE; when the UE completes cell updating accordingto the received cell updating response message and receives switching command again, the UE determines whether the radio resource control transaction identity in the switching command is identical with the radio resource control transaction identity in the cell updating response message, if yes, the UE does not execute the switching command, otherwise, executes the switching command. The invention also discloses a communication system. The inventive method and system can effectively control the execution process of the switching, prevent UE executing unnecessary retransmitted switching command, and reduce probability of error configuration.

Description

technical field [0001] The present invention relates to the field of communication technology, more specifically, a method, system and device for controlling user equipment cell handover. Background technique [0002] In the mobile communication network defined by the 3rd generation partnership project (3GPP, 3rd generation partnership project), when the user equipment (UE) moves to the edge of the cell, the radio network controller (Radio Network Controller, RNC) will Reports the initiation of the cell handover procedure. [0003] refer to figure 1 As shown, in the prior art, when the link quality is poor, after the RNC sends a handover command to the user equipment through an acknowledgment (AM) mode, the steps for the user equipment to initiate a cell handover process include: [0004] Step 101. When the user equipment moves to the cell edge, the user equipment sends a measurement report to the base station. [0005] Step 102, after receiving the measurement report, th...

Problems solved by technology

[0021] The present invention provides a method, system and device for controlling cell handover of user equipment, which solves the problem that in the prior art, after user equipment performs cell update due to radio link failure, configuration is performed according to a handover command retransmitted at the RLC layer, which causes a problem with the network side The configuration is inconsistent, causing the physical layer of the user equipment to lose synchronization again and causing interference to other online user equipment
