Abstract
One example method includes receiving, by a network slice selection function network element, a first message from a mobility management network element, where the first message includes network slice selection assistance information (NSSAI) subscribed to by a terminal and slice subscription information of n third-party service providers (SPs) corresponding to the NSSAI subscribed to by the terminal, and slice subscription information of a third-party SP comprises a first identifier. The network slice selection function network element can obtain, based on the first identifier, first mapping information corresponding to each third-party SP. The network slice selection function network element can determine allowed NSSAI for the terminal based on the NSSAI subscribed to by the terminal and the first mapping information, where the allowed NSSAI is used to indicate one or more network slices that the terminal is allowed to access in a visited network of the terminal.
