1. A method for service transmission, comprising:
performing, by a terminal device, a registration and a Non Public Network (NPN) Protocol Data Unit (PDU) session establishment on an NPN;
performing, by the terminal device, a tunnel establishment with a non-3rd Generation Partnership Project Interworking Function (N3IWF) through the NPN PDU session;
transmitting, by the terminal device, first indication information to an Access and Mobility Management Function (AMF) in a Public Land Mobile Network (PLMN) via the N3IWF during a registration to the AMF through the tunnel, wherein the first indication information contains NPN identifier information as PLMN Identifier (PLMN ID)+Network Identifier (NID), indicating that the terminal device accesses the PLMN via the NPN; and
obtaining, by the terminal device from the PLMN, at least one of policy information and a Quality of Service (Qos) parameter, which is delivered by the PLMN based on the first indication information indicating that the terminal device accesses the PLMN via the NPN,
wherein the method further comprises:
transmitting, by the terminal device via a PLMN PDU session, service data of a service unsupportable by the NPN, based on the at least one of the policy information and the Quality of Service (Qos) parameter,
obtaining, by the terminal device from the NPN, at least one of additional policy information and an additional QoS parameter, and
transmitting, by the terminal device via an NPN PDU session, service data of a service supportable by the NPN, based on the at least one of the additional policy information and the additional QoS parameter.
