1. A communication method comprising:
receiving, by a first access and mobility management function (AMF) device, a first request message, wherein the first request message comprises identifiers of a plurality of first network slices that a terminal requests to access and an identifier of a tracking area in which the terminal is located;
determining, by the first AMF device, from a plurality of radio access selection priority indexes based on radio access selection priority indexes respectively corresponding to the plurality of first network slices, a radio access selection priority index corresponding to a largest quantity of first network slices or a largest quantity of types of first network slices as a first radio access selection priority index; and
sending, by the first AMF device, a response message when the first AMF device determines that the tracking area supports a first network slice from the plurality of first network slices, wherein the response message comprises the first radio access selection priority index;
wherein the first radio access selection priority index is for selection of an access network device that supports the first network slice at the terminal.
