Abstract

The embodiment of the invention provides a cell switching method, a terminal and a base station, relates to the field of communication, can avoid the problem of offline caused by cell switching of theterminal in a high-speed motion state, and improves the user experience. The method comprises the following steps: a terminal sends a measurement report to a source base station, wherein the measurement report comprises the signal quality of at least one cell, and the at least one cell comprises a source cell; a source base station receives a measurement report sent by the terminal; if the sourcebase station determines that the signal quality of the target cell meets a first strategy, switching judgment information is acquired, wherein the switching judgment information is used for indicating the target base station to allow the terminal to access, and the target cell is a cell provided by the target base station; the source base station sends a first message to the terminal; and the first message comprises an identifier of the target cell. The terminal receives the first message sent by the source base station; and if the terminal determines that the signal quality of the source cell and the signal quality of the target cell meet a second strategy, switching from the source cell to the target cell. The present invention is used for cell handover.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell switching method, a terminal and a base station. Background technique [0002] With the development of road traffic in our country, people travel more and more frequently through expressways and high-speed railways. In order to meet the communication service requirements of terminals in high-speed motion, the communication requirements of terminals in high-speed motion are also getting higher and higher. . Since the terminal may move from one cell to another cell and then from another cell to the next cell in a short period of time when the terminal is moving at a high speed, the terminal frequently switches cells. Therefore, when the terminal is in a state of high-speed movement and frequently switches cells, the terminal may have left the coverage area of ​​the source cell of the cell to which the terminal is to switch before the cell switching is completed, resulting ...
