Abstract

The invention relates to the technical field of communication, especially to a cell reselection method and device, and aims at solving the problem that power loss of a user terminal is rapid due to frequent cell reselection in the prior art. The cell reselection method comprises that the user terminal adjusts the value of a cell reselection parameter according to the present residual electricity quantity of the terminal when the present residual electricity quantity is lower than a set electricity quantity threshold; and cell reselection is carried out according to the adjusted value of the cell reselection parameter. When the present residual electricity quantity is lower than the set electricity quantity threshold, the user terminal starts an autonomous reselection mode, namely, the value of the cell reselection parameter is adjusted according to the present residual electricity quantity, and cell reselection is carried out according to the adjusted value of the cell reselection parameter. The value of the cell reselection parameter is adjusted to improve the difficulty in cell reselection, reduce the cell reselection frequency of the user terminal, and further to reduce circuit loss of the user terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell reselection method and device. Background technique [0002] When a user terminal selects a certain cell as the current serving cell, it will reside in the selected cell and receive the list of neighboring cells to be tested broadcast by the system message of the serving cell. According to the measurement threshold broadcast by the serving cell and the priority of the neighboring cell to be measured, the user terminal independently performs periodic cell measurement according to the provisions of the protocol. When certain conditions are met, the user terminal will reselect one of the neighboring cells as the serving cell. This process is cell reselection. [0003] After the user terminal reselects to a cell under a different location area, routing area or tracking area, it needs to initiate a location area, routing area or tracking area update, and perform...
