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

The invention relates to a cell switching method, a measuring method, a device and a system, wherein the cell switching method comprises the following steps of: sending first measuring control information to user equipment, wherein a first reporting threshold and a filtering coefficient corresponding to each of adjacent cells are carried in the first measuring control information, and at least two adjacent cells are corresponding to different filtering coefficients; receiving a signal quality value which is fit with the first reporting threshold and reported by the user equipment, of each of the adjacent cells, wherein the signal quality value of each of the adjacent cells is obtained after the measured signal quality value of each of the adjacent cells is filtered by the user equipment according to the filtering coefficient corresponding to each of adjacent cells; and judging to perform cell switching according to the signal quality value which is fit with the first reporting threshold reported by the user equipment, of each of the adjacent cells. According to the embodiment of the invention, the accuracy of a base station for judging the cell switching is increased.

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 (...
