In LTE and NR systems, a public network system, i.e. a PLMN-based public land network, is typically deployed, which may be adapted for use with the communication system 100 as shown in fig. 1. But in some scenarios, such as office scenarios, home scenarios, factories, local users or administrators often have a local or private network layout for more efficient and secure management.

The premise of the terminal being capable of accessing the network for service communication is that the terminal needs subscription information/authorization information, security certificate information and the like of the accessed network.

In public network systems, after the terminal device leaves the factory, a user usually obtains required subscription information or certificate information in an offline manner, for example, in a manner of inserting a SIM. Subscription information and certificate information of the terminal may be stored in the SIM card.

In a non-public network, there is typically no dedicated physical store providing a non-public network with a similar way to a SIM card, while some private networks and terminal devices also have no room for inserting a SIM card. There is also no external interface for such a terminal device to be able to import subscription information or certificate information into the device. Therefore, how such terminal devices can obtain subscription authorizations and certificates for non-public networks is a challenge to be solved.

Based on the technical problems described above, the embodiment of the present application provides a wireless communication method, where a terminal device may remotely obtain subscription information and certificate information of an NPN network through a public network system or other trusted networks.
