[0079] The technical solution in this application will be described below with reference to the accompanying drawings.
[0080] Currently, the 3GPP standard organization has introduced the concept of a non-public network (non-public network, NPN). Alternatively, a non-public network is also called a private network. The network architecture of NPN refers to the network architecture of 5G core network (5G core, 5GC). Therefore, NPN also includes the functions of network elements similar to 5GC. For example, NPN also includes network elements such as AMF, SMF, UPF, AUSF and UDM. function.
[0081] see figure 1 , figure 1 (a) and (b) are schematic diagrams of a UE accessing a public network and a non-public network, respectively. The public network may be, for example, a public land mobile network (public land mobile network, PLMN). Such as figure 1 As shown in (a), the UE obtains the service provided by the PLMN through the access network and the core network of the PLMN. ...
