Cell reselection method and mobile terminal

摘要

Embodiments of the present invention provide a cell reselection method and a mobile terminal. In the embodiments of the present invention, whether a cell where signal measurement needs to be performed exists is determined according to a neighboring cell list and a reselection prohibited list; if a cell where signal measurement needs to be performed exists, signal measurement is performed on the cell where signal measurement needs to be performed and a current serving cell to obtain a measurement result; and if the measurement result satisfies a trigger condition of cell reselection, cell reselection is triggered. Therefore, when cell reselection needs to be performed, signal measurement is no longer performed on a cell in the reselection prohibited list and unnecessary signal measurement and cell reselection are avoided, thereby decreasing power consumption of a mobile terminal and prolonging standby time of the mobile terminal.

1. A cell reselection method performed by a mobile terminal, comprising:
determining, by the mobile terminal, according to a neighboring cell list and a reselection prohibited list, whether a cell on which signal measurement needs to be performed exists, wherein the cell is in the neighboring cell list but is not included in the reselection prohibited list; when the cell exists, performing, by the mobile terminal, the signal measurement on the cell and on a first cell currently serving the mobile terminal to obtain a measurement result; and when the measurement result satisfies a trigger condition of cell reselection, triggering cell reselection to select a second cell to serve the mobile terminal, wherein the neighboring cell list includes a plurality of neighboring cells of the first cell, and the reselection prohibited list includes a plurality of cells on which cell reselection is prohibited, wherein the reselection prohibited list is generated or updated based on a rule:
after M times of reselection are performed on the first cell and a portion of the plurality of neighboring cells within a predefined time period, adding a first group of cells to the reselection prohibited list, the first group of cells includes the first cell and the portion of the plurality of neighboring cells except a cell having the best signal stability, wherein M is a positive integer that is greater than or equal to a first threshold.
