Specifically, when the 5G terminal device 3 is R16 standard, the 5G core network is R16 standard, and the 5G base station is R15 standard, the 5G terminal device 3 first initiates a registration request (i.e. the second session establishment request) for establishing an Ethernet type PDU session with R16 standard to the 5G base station, and if the 5G base station can establish the Ethernet type PDU session with R16 standard, the 5G terminal device directly accesses the 5GLAN network based on the established R16 standard session.
