Abstract

The invention relates to a communication method and system and a computer readable storage medium, and relates to the technical field of communication. The method of the present disclosure comprises: an access network receiving a first registration request sent by a UE of a private network, the first registration request comprising an identifier of the UE and an identifier of a network slice; the access network identifies that the UE is the UE of a private network according to the identifier of the UE, and determines an access and mobility management function (AMF), a session management function (SMF) and a user plane function (UPF) corresponding to the network slice according to the identifier of the network slice; the access network sends a second registration request to the AMF, the second registration request comprising the identifier of the UE and the identifier of the network slice, so that the AMF confirms to provide service for the UE, and a session is established by the SMF and the UPF corresponding to the network slice; and the access network receives a registration success message returned by the AMF and establishes connection with the UPF.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a communication method, system and computer-readable storage medium. Background technique [0002] In the 5GtoC (5G consumer-oriented) network, the establishment process of the user plane data link is relatively complicated and the response time is long. [0003] For example, during the establishment of a user plane data link, AMF (Access and Mobility Management Function, access and mobility management function), SMF (Session Management Function, session management function), UPF (User Plane Function, user Plane function) and other network element selection process, it is necessary to establish GTP-U (GPRS Tunnel Protocol-User Plane, user plane GPRS tunnel) between (R)AN ((Radio) Access Network, (wireless) access network) and UPF protocol) tunnel. Contents of the invention [0004] The inventors found that in the current establishment process of the user pl...
