Cell selection method and terminal equipment

Abstract

The embodiment of the invention discloses a cell selection method and terminal equipment. The method is applied to the terminal equipment, and the method includes the following steps: selecting a cellto reside based on pre-stored carrier frequency point information; and under the condition that the cell selected based on the carrier frequency point information meets a preset non-resident condition, performing network searching based on other carrier frequency points other than the carrier frequency point corresponding to the carrier frequency point information to select the cell where the terminal equipment resides. According to the method, the cell selection can be preferentially performed based on the pre-stored carrier frequency point information, so that the network searching time ofthe terminal equipment can be reduced, and meanwhile, a trigger condition is set, that is, under the condition that the cell selected based on the carrier frequency point information meets the presetnon-resident condition, the terminal equipment can search networks at other carrier frequency points, and thus a better neighborhood cell can be selected for registration and residence.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a cell selection method and terminal equipment. Background technique [0002] In wireless communication, it is usually necessary to perform cell selection, cell reselection, or cell switching on terminal equipment. In order to speed up network search, wireless chip manufacturers generally store cell selection schemes in advance, such as recording historically registered frequency point information, Configure information about registered historical cell numbers, configure priority frequency band information, configure common frequency point information, etc. [0003] When the terminal device selects a cell, it will select a suitable cell for registration and camping based on the recorded historical registration frequency point information, information about the configured registration history cell number, configured priority frequency band information, or configur...

Problems solved by technology

[0004] The embodiment of the present invention provides a cell selection method to solve the problem that when a terminal device selects an abnormal cell or a non-optimal cell to initiate registration through pre-stored information, it cannot and has no opportunity to select a normal cell or an optimal cell to initiate registration
