Description
Technical Field
The present invention relates to wireless communication technologies, and in particular, to an access method, a terminal, and a base station for a non-public network.
Background
The fifth generation mobile communication system (5G) network expands mobile communication services from mobile phones, mobile broadband, and large-scale machine type communication to a new application field, so-called vertical field, with special requirements for communication services. To meet the needs of the industry vertical, 5G networks have introduced the concept of Non-Public networks (NPN), such as networks for certain enterprises/plants. An unauthorized User Equipment (UE), i.e., a UE not associated with the enterprise, will not attempt to access the non-public network, which may cause the network to consume resources to deny the unauthorized UE, thereby causing the enterprise's UE to be unable to access the NPN. The UEs of the enterprise do not attempt to access networks to which they are not authorized. For example, some enterprise UEs may be restricted to access only the non-Public networks of the enterprise, even if there is Public Land Mobile Network (PLMN) coverage in the same geographic area.
5G networks introduce the concept of network slicing, which allows operators to offer customized networks. For example, there may be different requirements on the functionality (e.g., priority, billing, policy control, security, and mobility), differences in performance requirements (e.g., delay, mobility, availability, reliability, and data rate), or they may only be used to serve a particular user (e.g., MPS user, public safety user, enterprise customer, rover, or hosted Mobile Virtual Network Operator (MVNO)). A network slice may provide the functionality of a complete network including radio access network functions, core network functions (e.g., possibly from different vendors) and IP Multimedia Subsystem (IMS) functions. A network may support one or more network slices. The 5G network may implement the Non-public network by way of a Non-stand-alone NPN, e.g., by way of a network slice(s) assigned for the NPN.
It is proposed that the Access control may be implemented by a Closed Access Group (CAG), which is similar to a Closed Subscriber Group (CSG) of a fourth generation mobile communication system (4G) and is used for identifying one or more special cells.
If the above access control scheme is adopted, that is, the CAG is adopted to perform access control, although access control can be implemented to meet the requirement of saving network resources, the following problems exist: 1. the concept of CAG is additionally introduced, so that corresponding workloads such as signing, configuration, code number management and the like are additionally brought; 2. the introduction of the CAG brings about the change of a large number of flows of a core network, and almost all flows of mobility management such as registration, switching and the like are modified; 3. the introduction of the CAG will cause the core network to have two kinds of access control, namely the access control of the CAG and the access control of the slice, and the flow is relatively redundant.

step 102: the terminal accesses the base station when determining that the broadcast message carries first slice selection auxiliary information and the first slice selection auxiliary information is in a slice selection auxiliary information list obtained in advance; the first slice selection assistance information corresponds to a first non-public network.
In an optional embodiment of the present invention, the terminal determines that the first slice selection assistance information is in a pre-obtained list of slice selection assistance information, and the method further comprises: the terminal obtains a slice selection auxiliary information list in a pre-configured mode; or, the terminal obtains the slice selection auxiliary information list from the core network device through the first specific signaling.

As an example, the first specific signaling is a signaling in an existing processing flow of the terminal. For example, the first specific signaling may be signaling of the terminal during a registration process.
For example, the terminal sends a Registration Request (Registration Request) to the access network device; the Access network equipment sends the registration request to core network equipment, such as an Access and Mobility Management entity (AMF), and the AMF processes the registration of the terminal; after the processing is completed, the AMF sends Registration Accept (Registration Accept) to the terminal through the access network equipment, and finally the terminal sends Registration Complete (Registration Complete) to the AMF through the access network equipment, thereby completing the Registration of the terminal. In the foregoing process, the core network device (e.g., the AMF) may carry the slice selection assistance information list through Registration Accept (Registration Accept) signaling, so that the terminal obtains the slice selection assistance information list based on the Registration Accept (Registration Accept) signaling.
