Problems solved by technology

However, it takes seconds to complete a cell reselection, and through field tests, it is found that the highest ranked cell changes very frequently
Then, the cell that was originally prohibited from access may still be prohibited from accessing after being re-included in the cell reselection candidate list of the terminal device in the process of re-participating in cell reselection, but the terminal device still needs to These cells are verified, which leads to a large power consumption of the terminal equipment

Abstract

A method and device for cell reselection, the method comprising: during the process of cell reselection, determining that a second cell is prohibited from accessing; determining the highest-ranked cell according to cell reselection criteria; when the highest-ranked cell changes, and When the first condition is met, the access prohibition on at least one cell is lifted, the at least one cell is a cell that is prohibited from access during the cell reselection process, and the at least one cell includes the second cell and / or a cell of the same frequency as the second cell. Through the first condition, when a cell is prohibited from accessing, the terminal device can reduce the number of checks on the cell, thereby reducing the ineffective power consumption of the terminal device, and also making the check of the cell by the terminal device more efficient. more effective.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a cell reselection method and device. Background technique [0002] At present, when performing cell reselection, the terminal device sorts the cells satisfying the S criterion in the candidate list for cell reselection according to the R criterion. The cells satisfying the S criterion can be simply understood as the cells whose signal quality meets certain requirements. , sorting according to the R criterion, for example, sorting according to the signal quality of the cells from high to low. For the highest-ranked cell, that is, the highest-ranked cell, when the terminal device stays in the current serving cell for longer than 1s, and the time for which the highest-ranked cell is not the terminal device’s serving cell is greater than the preset threshold TreselectionRAT, the terminal device The system information of the cell with the highest ranking is re...
