1. A communication method, comprising:
receiving, by a terminal device, first information indicating at least one supported network slice, wherein the at least one supported network slice comprises a network slice supported by a first cell currently accessed by the terminal device or by a first access device currently accessed by the terminal device;
receiving, by the terminal device, second information indicating at least one allowed network slice; and
processing, by the terminal device, a session establishment request of a first service based on the first information and the second information, the processing further comprising at least one of the following:
if a first network slice belongs to the at least one supported network slice and the at least one allowed network slice, sending the session establishment request of the first service, wherein the first network slice corresponds to the first service; and
if a first network slice does not belong to the at least one supported network slice or the at least one allowed network slice, stopping the session establishment request of the first service.
