GSM - UMTS Public Land Mobile Network (PLMN) Access Reference Configuration
The present document describes the reference configuration for access to a PLMN.
A user accesses a PLMN via a number of interfaces, including the MS-BS (in A/Gb mode and GERAN Iu mode), UE-UTRAN (in UTRAN Iu mode), UE-E-UTRAN, and UE-5G-AN interface. The purpose of this document is to indicate the possible access arrangements that may be used in conjunction with the MS-BS (in A/Gb mode and GERAN Iu mode), UE-UTRAN (in UTRAN Iu mode), UE-E-UTRAN, and UE-5G-AN interface.
