Cell reselection method and device

Abstract

The present disclosure relates to a cell reselection method and device. The method includes: when staying in the current serving cell, judging whether the neighboring cell satisfies the cell reselection condition; when the neighboring cell satisfies the cell reselection condition, acquiring cell reselection information corresponding to the neighboring cell; judging whether the cell reselection information is consistent with Match the historical ping-pong reselection records; when the cell reselection information matches any of the ping-pong re-selection records in the historical ping-pong re-selection records, determine the current cell re-selection time and the historical cell corresponding to any of the ping-pong re-selection records Whether the time difference between the reselection times is greater than the preset time difference; when the time difference is greater than the preset time difference, reselect the neighboring cell as the current serving cell to reside in the neighboring cell. This technical solution can effectively reduce the frequency of cell ping-pong reselection, reduce the power consumption of the terminal due to ping-pong reselection, prolong the standby time to a certain extent, and improve the user experience of the terminal.

Description

Technical field [0001] The present disclosure relates to the field of communication technology, and in particular to a method and device for cell reselection. Background technique [0002] At present, during the cell reselection process, ping-pong reselection problems often occur due to improper network reselection parameter configuration. For example, when a terminal resides in cell A, it may select cell B according to the current cell reselection parameters. When the terminal resides in cell B, cell A may be selected again according to the cell reselection parameters. This frequent switching between the two cells is called ping-pong reselection, but ping-pong reselection will cause the terminal’s standby current Continue to be high, which in turn affects the terminal's standby time and user experience. Summary of the invention [0003] The embodiments of the present disclosure provide a cell reselection method and device. The technical solution is as follows: [0004] According...

Problems solved by technology

[0002] At present, in the process of cell reselection, the problem of ping-pong reselection often occurs due to improper configuration of network reselection parameters. For example, when a terminal camps in cell A, it may select cell B according to the current cell reselection parameters. When the terminal stays in cell B, it may select cell A again according to the cell reselection parameters. This phenomenon of frequent switching between the two cells is called ping-pong reselection, but ping-pong reselection will cause the standby current of the terminal Sustained high, thereby affecting the standby time and user experience of the terminal
