Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] An embodiment of the present invention provides a method for UE to perform cell reselection, which solves the above-mentioned problem of UE frequent ping-pong reselection by optimizing the reselection evaluation process, and reduces unnecessary power consumption of the UE.

[0024] The inventor noticed that the reason for ping-pong reselection in the prior art is that when UE performs cell reselection, it only uses the parameters about neighboring cells in the ...

Abstract

An embodiment of the invention discloses a cell reselection method of user equipment UE, a user device and a system. The cell reselection method of the user equipment UE includes: a first judgment step, a current effective first reselection parameter is used for judging whether adjacent cells meet a first reelection evaluation condition, wherein the first reelection parameter is from current serving cell system information and about neighbor cells or from saved adjacent cell system information and about the adjacent cells; and a second judgment step, when a judgment result in the first judgment step is that the adjacent cells meet the first reelection evaluation condition, whether the adjacent cells meet a second reelection evaluation condition is judged according to a second reelection parameter obtained from current adjacent cell system information, and on yes judgment, the adjacent cells are reelected. The cell reselection method of the user equipment UE solves the problem of frequent reelection of the UE and reduces unnecessary power consumption the UE through optimization of a reelection evaluation process.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method for user equipment UE to perform cell reselection, and a user equipment and a communication system for realizing the method. Background technique [0002] In the field of communication, user equipment (UE) in idle (IDLE) mode will cause the process of reselecting the serving cell due to factors such as location changes and signal changes. Those skilled in the art know that in the current LTE36.304 protocol, cell reselection needs to meet the following reselection evaluation conditions: [0003] 1. Neighboring cells satisfy the S criterion, that is, it is required that both the cell selection transmit power level value and the cell selection quality value are greater than zero. [0004] 2. Neighboring cells meet the reselection threshold conditions. Specifically, the same-frequency neighboring cells need to meet the R criterion, and the different-frequen...
