Problems solved by technology

[0016] When the UE frequently performs cell reselection between these two cells, it will not only consume the power of the UE, but also the frequent changes of the cell where the UE resides may make it difficult for the UE to access the network smoothly.

Abstract

The invention provides a cell reselection method, a cell reselection device and user equipment. The method comprises the following steps: determining at least two strong cells from a same-frequency cell and a different-frequency cell with the same priority as a current resident frequency; for the at least two strong cells, determining the number of wave beams which exceed a signal quality threshold value and are contained in each strong cell, with the same signal quality threshold value being adopted by the same-frequency cell, or the same-frequency cell and a pilot-frequency cell with the same priority as the current resident frequency; and selecting a cell with the largest number of beams exceeding a signal quality threshold value to reside. According to the invention, ping-pong reselection can be avoided, so that the power consumption of the UE is reduced and the UE is ensured to smoothly access the network.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a cell reselection method, device and user equipment. Background technique [0002] In a mobile communication system, handover and cell reselection are extremely important components. Specifically, when a UE (User Equipment, user equipment) leaves a cell and enters another cell, the original cell (serving cell) received by the UE The signal of the cell) is getting weaker and weaker, while the signal of the cell it is entering is getting stronger and stronger. In order to maintain the quality of the signal received by the UE, the UE must be switched from the original base station (or cell) to a newly entered base station (or cell) with stronger signals. For UEs in the connected state, this transition between base stations is called handover; for UEs in the idle state, the change of the cell where the UE resides is completed through the cell reselection (Res...
