CELL RESELECTION METHOD AND APPARATUS

This application provides a cell reselection method and an apparatus. The method includes: A terminal device sends a radio resource control RRC setup request message to a first radio access network device a plurality of times. The terminal device receives a response message for the RRC setup request message within a preset time. The terminal device determines, based on a first preset threshold and a quantity of consecutive times that the response message is not received, whether to perform cell reselection, or the terminal device determines, based on a third preset threshold and a quantity of times that the RRC setup request message is sent or a quantity of times that the response message for the RRC setup request message is received, whether to trigger a cell reselection mechanism.
