Abstract

The embodiment of the invention provides a cell replacement method and a cell replacement device. The method comprises the following steps of: determining a target cell for cell replacement as a micro cell, wherein the cell replacement comprises cell reselection or cell handover; determining the mobile state or mobile speed of UE (user equipment); and carrying out cell replacement judgment aiming at the target cell according to the moving state or the moving speed of the UE. According to the embodiment of the invention, during the process of carrying out the cell replacement judgment aiming at the micro cell, the moving state or the moving speed of the UE is considered so as to reduce unnecessary cell replacement aiming at the micro cell, thus the system burden and the UE power consumption which are caused by frequent cell replacement are lowered.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a cell replacement method and device. Background technique [0002] The wireless communication system can provide wireless services such as voice and data. The usual wireless communication system is a wireless system with multiple access, such as FDMA (Frequency Division Multiple Access, Frequency Division Multiple Access), TDMA (Time Division Multiple Access, Time Division Multiple Access), CDMA (Code Division Multiple Access, Code Division Multiple Access) Address), OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access), SC-FDMA (Signal Carrier-Frequency Division Multiple Access, Single Carrier Frequency Division Multiple Access). In a wireless communication system, a base station transmits data and / or control information to a user equipment (UE, User Equipment) on a downlink, and receives ...
