Access to snpn by using credential owned by entity separated from snpn, and support for f1 interface therefor

Abstract

Provided are a method and apparatus for: access to a stand-alone non-public network (SNPN) by using credential owned by an entity separated from the SNPN; and support for an F1 interface therefor. User Equipment (UE) operating in a wireless communication system receives system information from the stand-alone non-public network (SNPN). The system information includes information about whether or not the SNPN supports underconfigured UE. The UE transmits a first registration request message to the SNPN, on the basis of the information about whether or not to support the underconfigured UE, and receives, from the SNPN, a registration reject message as a response to same. The registration reject message includes information about home SPs supported by the SNPN. The UE performs registration by selecting at least one home SP from which the UE desires to receive a service from among the home SPs supported by the SNPN.
