Problems solved by technology

However, when the terminal device exits PSM, it can only search for a cell based on the frequency point where it resided last time, and select a suitable cell. As a result, in the inter-frequency networking mode, the terminal device can only perform a full-frequency network search when selecting a cell.

Abstract

The present application provides a method and terminal device for selecting a cell. The method for selecting a cell includes: before the terminal device enters the low power consumption mode PSM, acquiring first information, where the first information includes information of a plurality of frequency points, at least two frequency points are different, and the frequency points are used for the cell Search: After the terminal device exits the PSM, it performs cell search based on multiple saved frequency points, and selects an appropriate serving cell. The technical solution provided by the present application can enable a terminal device to perform a cell search according to multiple frequency points and timely select a serving cell when it exits the PSM for cell selection.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and terminal device for selecting a cell. Background technique [0002] Due to the advantages of low power consumption, wide coverage, low cost, and large capacity of narrowband IoT technology, it can be widely used in the field of IoT. However, NB-IoT technology is not widely used in scenarios where terminal devices are moving. The reason is that in the scenario where the terminal device moves, network services are constantly changing. The terminal device needs to switch the serving cell in time. Considering the service life of the terminal device, the terminal device cannot always be in an active state to detect changes in network services. [0003] In the prior art, in order to improve the service life of the terminal device, the terminal device is made to work in a low power consumption mode (power saving mode, PSM). However, when the terminal devi...
