Cell reselection method and apparatus

A communication apparatus, comprising at least one circuitry configured to:

• send a radio resource control RRC setup request message to a first radio access network device a plurality of times, wherein
• determine, 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 determine, 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 is received, whether to perform cell reselection, wherein the response message is for the RRC setup request message within a preset time, the first preset threshold is received from a second radio access network device and stored, and the second radio access network device is a radio access network device accessed by a terminal device before the terminal device accesses the first radio access network device.
