1. A network slicing method, comprising:
sending, by a terminal, a target protocol data unit (PDU) session establishment request to a local session management function (SMF), wherein the PDU session establishment request comprises: initial network slice information, data network name (DNN) information, terminal identification information, and PDU session identification information, and wherein a local SMF forwards the PDU session establishment request to the local unified data management UDM so as to request a user subscription, the local UDM obtains, according to the terminal identification information, target network slice information corresponding to the terminal identification information and notifies the local SMF, and then the local SMF replaces the initial network slice information with the target network slice information and determines to establish a PDU session; and
receiving, by the terminal, a bearer establishment notification sent by a base station, wherein the bearer establishment notification is determined according to an indication of a local access and mobility management function (AMF) to establish a radio bearer, and the bearer establishment notification is used to indicate the terminal to establish the radio bearer, wherein the local AMF indicates, after the local SMF indicates to confirm establishment of the PDU session, the base station to establish the radio bearer.
