Problems solved by technology

[0004] However, in the scenario where the signal change rules of neighboring cells are inconsistent, such as the coexistence of large and small base stations, the UE enters a tunnel or the signal change characteristics of the handover boundary between the serving cell and the neighboring cell are different. Quality evaluation is inaccurate, resulting in inaccurate judgment of cell handover by the base station

Abstract

A cell handover method, measurement method, device, and system are disclosed. The cell handover method comprises: sending a first measurement control message to a user equipment (UE), wherein the first measurement message carries a first report threshold and filter coefficient of each neighboring cell, and at least two neighboring cells are corresponding to different filter coefficients; receiving a signal quality value of each neighboring cell satisfying the first report threshold reported by the UE, wherein the signal quality value of each neighboring cell is obtained after the UE filters the signal quality value measured according to the filter coefficients corresponding to the neighboring cells; and determining cell handover according to the signal quality value of each neighboring cell satisfying the first report threshold reported by the UE. The embodiment of the present invention enables the evolved Node B to determine cell handover in a more accurate manner.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a cell handover method, measurement method, device and system. Background technique [0002] In the 3rd-Generation Partnership Project (The 3rd-Generation Partnership Project; hereinafter referred to as: 3GPP) Long Term Evolution (hereinafter referred to as: LTE) system, when a user equipment (User Equipment; hereinafter referred to as: UE) performs cell handover , usually includes two stages of handover preparation and handover execution. In the handover preparation phase, the UE's physical layer periodically detects the signal quality of the serving cell and neighboring cells. ) layer reports the filtered signal quality, the RRC layer filters the signal quality according to the relevant definitions in the 3GPP TS 36.331 standard, and the UE reports the signal quality of neighboring cells that meet the reporting conditions to the evolved base station (...
