Problems solved by technology

However, for many stationary terminals (such as terminals for meter reading and other services), such terminals do not move and are located indoors with relatively poor signal coverage. Once the indoor signal is weaker than -52dBm, the terminal will frequently start Measurement of neighboring cells, resulting in a substantial increase in terminal power consumption

Embodiment Construction

[0035] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0036] An embodiment of the present invention provides a cell reselection method, such as figure 1 As shown, the method includes:

[0037] Step 101: Determine the state information of the terminal; the state information is used to indicate the current motion state of the terminal;

[0038] Step 102: When it is determined that the running state is a mobile state, adopt the reselection parameters broadcast by the network side; when it is determined that the running state is a static state, modify the reselection parameters broadcast by the network side.

[0039] In the embodiment of the present invention, if the terminal is in a mobile state, the reselection parameters broadcast by the network side can be used to solve the problem of terminal reselection lag in the mobile state; if the terminal is in a static state, the reselection parameters broadcast by the ne...

Abstract

Embodiments of the present invention provide a cell reselection method, device, and computer-readable storage medium. The method includes: determining state information of a terminal; the state information is used to indicate the current movement state of the terminal; determining the When the running state is a mobile state, the reselection parameters broadcast by the network side are used; when the running state is determined to be a static state, the reselection parameters broadcast by the network side are corrected.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a cell reselection method, device and computer-readable storage medium. Background technique [0002] In the existing cell reselection process, the cell broadcasts a set of cell reselection parameters, and all terminals perform reselection according to the uniform cell reselection parameters. For example: reselection start threshold (when the signal of the serving cell is lower than this value, the measurement of the adjacent cell is started), reselection delay time (when the signal of the adjacent cell is higher than the signal of the current cell for a period of time, the terminal reselects to the target cell ). [0003] For the cellular Internet of Things NB-IOT system, in the 3GPP R13 version of the specification, the maximum value of the cell reselection start threshold is -70dBm. However, since NB-IOT is often deployed in a low-frequency band (for exa...
