Embodiment 1

[0029] Such as figure 1 As shown, the present invention provides a cell reselection method, comprising the following steps:

[0030] 101. When the first cell where the terminal is currently camped on satisfies the camping condition and a second cell with better signal quality is found, update the task scheduling of the terminal so that the task is: perform the task scheduling in the discontinuous reception cycle of the terminal The measurement task of the above-mentioned first cell, the monitoring task of the paging channel of the above-mentioned first cell, and the reselection task for the purpose of camping on the above-mentioned second cell;

[0031] In this embodiment, after the update, the task of measuring the neighboring cells of the first cell is deleted from the tasks performed in the discontinuous reception cycle of the terminal, and the above-mentioned reselection task is added;

[0032] 102. Use the idle time period of the discontinuous reception cycle to perform ...

Embodiment 2

[0042] Such as figure 2 As shown, the present invention provides a cell reselection method, comprising the following steps:

[0043] 201. When the first cell where the terminal is currently camped on satisfies the camping condition and a second cell with better signal quality is found, update the task scheduling of the terminal so that the task is: perform the task scheduling in the discontinuous reception period of the terminal The measurement task of the above-mentioned first cell, the monitoring task of the paging channel of the above-mentioned first cell, and the reselection task for the purpose of camping on the above-mentioned second cell;

[0044] In this embodiment, after the update, the task of measuring the neighboring cells of the first cell is deleted from the tasks performed in the discontinuous reception period, and the above-mentioned reselection task is added;

[0045] 202. Use the idle time period of the discontinuous reception cycle to perform the reselecti...

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a cell reselection method and a mobile terminal. Wherein, the method includes: when performing a reselection task for the purpose of camping on a second cell with better signal quality, not leaving the first cell where the current camping is performed, and maintaining the measurement of the first cell and the paging channel monitoring; executing the reselection task for the purpose of camping in the second cell; when the reselection task is completed, if the reselection task is successfully performed, the terminal stays in the second cell, and if it fails, the terminal resumes to the second cell The routine measurement task of a cell still resides in the first cell. The invention also discloses a mobile terminal. By implementing the embodiment of the present invention, it is possible to keep monitoring the paging channel of the original cell without leaving the cell where the cell is currently residing when performing the reselection task of a better cell, so as to avoid missing paging. Re-election latency is greatly reduced by eliminating the need to re-park.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a cell reselection method and a mobile terminal. Background technique [0002] In the existing mobile terminals, in order to save the power of the mobile phone, the power-saving scheme of Discontinuous Receive (DRX) is generally used. Specifically, the processor will turn off the receiver and put itself into a low-power sleep mode. , only wakes up once in a while to execute the task. When the terminal camps in a cell, generally, the tasks of each DRX cycle include: measurement of the current camping cell and its neighboring cells, and monitoring of the paging channel. That is, after the terminal wakes up, it detects the signal quality of the cell it is currently camping on and its neighboring cells, judges whether cell reselection is necessary, and judges whether there is paging, so as to respond to paging in time. [0003] Cell reselection is required in the following t...
