Abstract

The embodiment of the invention discloses a cell switching control method, which comprises the following steps: after receiving a measurement report, determining a plurality of preparation cells; sending a switching request message to a base station eNB of each preparation cell, wherein when a plurality of cells of one eNB belong to the preparation cells, the switching request message carrying information for indicating corresponding preparation cells is sent to the eNB; receiving response information of each eNB; and selecting a switching target cell, and indicating UE to perform cell switching. The embodiment of the invention also discloses a device for implementing the method and a communication system. The embodiment of the invention provides a signaling transmission system and methodin the process of preparing the switching of the plurality of preparation cells, ensures the normal cell switching process under the condition that the plurality of preparation cells belong to one eNB, and provides effective functional supplementation for the prior multi-preparation cell switching technology.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, more specifically, to a multi-prepared cell (Muti-prepared Cell) handover method control, device and communication system. Background technique [0002] In order to solve the problem of unsuccessful handover caused by radio link communication failure, the Long Term Evolution (LTE) system proposes a multi-preparation cell handover method, the process of which is as follows figure 1 shown, including the following steps: [0003] In step S101, a user equipment (UE) sends a measurement report to a source base station (Source eNB). [0004] Step S102, Source eNB selects multiple prepared target cells for the UE when making a handover decision, assuming that the base stations including these prepared cells include target base station 1 (Target eNB1), target base station 2 (Target eNB2) and target base station n(Target eNBn). [0005] Step S103, Source eNB sends a handover reques...
