US 11,310,729 B2 · Cell search method and communications apparatus

Abstract

A cell search method and a communications apparatus are provided. The method includes the following: before searching for a cell, a terminal device may determine, with reference to historical access information of another terminal device, whether there is a cell at the location, and adjust, based on a determining result, a value of a search parameter used to search for a cell. For example, if there is a cell, the terminal device may adjust the search parameter to accelerate a search. If there is no cell, the terminal device may perform no search, or adjust the search parameter to reduce an unnecessary cell search performed by the terminal device, so that power consumption of the terminal device can be reduced.

Dependent claims

A cell search method, comprising:

obtaining, by a first terminal, first information before searching for a cell at a first location, wherein the first information comprises historical access information that is obtained from one or more second terminals near the first terminal in a short-distance communication manner and that corresponds to each second terminal at the first location, wherein historical access information corresponding to the first location indicates whether there is a cell at the first location;
determining, by the first terminal, a value of a search parameter of the first terminal at the first location based on second information, wherein the second information comprises the first information;
and
searching, by the first terminal, for a cell at the first location based on the value of the search parameter.
