Network access method, terminal, access network and core network

Abstract

The disclosure discloses a network access method, a terminal, an access network and a core network, and belongs to the technical field. The method includes: obtaining a network service identifier of the requested network service; obtaining access information according to the network service identifier, the access information including a network slice identifier and a network slice type identifier corresponding to the network service identifier; according to the network slice type identifier, Determine the access mode corresponding to the network slice identifier; access the network slice corresponding to the network slice identifier according to the access mode corresponding to the network slice type. The terminal in this disclosure obtains access information including at least the network slice type identifier according to the network service identifier, and then accesses the network slice according to the access mode corresponding to the network slice type identifier, thereby avoiding the problem of not being able to access the network correctly. The service cannot be obtained by slicing, which improves the service quality.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a network access method, a terminal, an access network and a core network. Background technique [0002] In the 5G (5th-Generation, fifth-generation mobile communication technology) network scenario, the network can be divided into multiple network slices according to the supported business scenarios and services. Terminals can obtain the network services provided by the network slices by accessing the network slices. According to network functions, network slicing includes type A network slicing, type B network slicing and type C network slicing. Among them, type A network slicing has a dedicated access network and a dedicated core network, type B network slicing has a general access network and a dedicated core network, and type C network slicing has a general access network and a common core network. For the three types of network slicing, the terminal a...

AI Technical Summary

Problems solved by technology

[0003] In practical applications, when the application in the terminal needs to obtain a certain network service due to business requirements, the terminal randomly uses an access method to initiate network access to the network slice that provides the network service. If there is no corresponding access method, the terminal will not be able to access the network slice, let alone obtain services
