Abstract
This application discloses a communication method and apparatus. A first AMF device receives a first request message, where the first request message includes an identifier of a first network slice that a terminal requests to access and an identifier of a tracking area in which the terminal is located. When the first AMF device determines that the tracking area supports the first network slice, the first AMF device sends a response message, where the response message includes a first radio access selection priority index corresponding to the first network slice. The first radio access selection priority index is for selection of an access network device that supports the first network slice at the terminal. Even if an access network device currently accessed by the terminal does not support the first network slice, the terminal may re-access the access network device that supports the first network slice.
