Abstract

The present disclosure relates to: a communication technique merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. A terminal in a wireless communication system according to one embodiment of the present invention can select a server of an onboarding stand-alone non-public network (SNPN).

First claim

The invention claimed is:

1. A method by a stand-alone non-public network (SNPN) to which a user equipment (UE) is onboarding in a wireless communication system, the method comprising:
receiving, from the UE, a unique identifier of the UE configured as a network access identifier;
selecting a default credential server based on information included in realm part of the network access identifier; and
receiving, from the default credential server, address information of a provisioning server during authentication procedure for the UE.

2. The method of claim 1 , further comprising selecting a session management function (SMF) and a user plane function (UPF) corresponding to the provisioning server selected by the default credential server.

3. The method of claim 1 , further comprising:
transmitting, to the default credential server, an authentication request including authentication information about the UE; and
receiving, from the default credential server, a response indicating success of authentication of the UE.

4. The method of claim 1 ,
wherein the information included in realm part of the network access identifier is corresponding to an address of the default credential server.

5. A method by a user equipment (UE) onboarding to a stand-alone non-public network (SNPN) in a wireless communication system, the method comprising:
transmitting, to the SNPN, a unique identifier of the UE configured as a network access identifier; and
performing a UE authentication procedure with a provisioning server selected by a default credential server corresponding to information included in realm part of the network access identifier.

6. The method of claim 5 ,
wherein the information included in realm part of the network access identifier is corresponding to an address of the default credential server.

7. The method of claim 5 , wherein the provisioning server is selected by the default credential server in case that the authentication procedure for the UE is successful.

8. A stand-alone non-public network (SNPN) to which a user equipment (UE) is onboarding, in a wireless communication system, the SNPN comprising:
a transceiver; and
a controller coupled with the transceiver and configured to control to:
receive, from the UE, a unique identifier of the UE configured as a network access identifier,
select a default credential server based on information included in realm part of the network access identifier, and
receive, from the default credential server, address information of a provisioning server during authentication procedure for the UE.

9. The SNPN of claim 8 , wherein the controller selects a session management function (SMF) and a user plane function (UPF) corresponding to the provisioning server selected by the default credential server.

10. The SNPN of claim 8 , wherein the controller controls to transmit, to the default credential server, an authentication request including authentication information about the UE, and controls to receive, from the default credential server, a response indicating success of authentication of the UE.

11. The SNPN of claim 8 , wherein the information included in realm part of the network access identifier is corresponding to an address of the default credential server.

12. A user equipment (UE) onboarding to a stand-alone non-public network (SNPN) in a wireless communication system, the UE comprising:
a transceiver; and
a controller coupled with the transceiver and configured to control to:
transmit, to the SNPN, a unique identifier of the UE configured as a network access identifier, and
perform a UE authentication procedure with a provisioning server selected by a default credential server corresponding to information included in realm part of the network access identifier.

13. The UE of claim 12 , wherein the information included in realm part of the network access identifier is corresponding to an address of the default credential server.

14. The UE of claim 12 , wherein the provisioning server is selected by the default credential server in case that the authentication procedure for the UE is successful.
