Communication method and communications apparatus to implement a network slice based service in a central unit (CU)-distributed unit (DU) architecture

摘要

This application discloses a communication method and a communications apparatus. The method includes: sending, by a central unit of a radio access network (RAN), to a distributed unit of the RAN, a UE context setup request message, wherein the UE context setup request message comprises an identifier of a bearer to be established, and indication information of a network slice corresponding to the bearer; and sending, by the distributed unit of the RAN, to the central unit of the RAN a response message in response to the UE context setup request message.
