NETWORK NODE, USER EQUIPMENT, AND METHOD FOR SAME

Title:

NETWORK NODE, USER EQUIPMENT, AND METHOD FOR SAME

Document Type and Number:

WIPO Patent Application WO/2021/246164

Kind Code:

A1

Abstract:

This network node (21) associated with a first HPLMN (Home Public Land Mobile Network) prepares a list which indicates at least one VPLMN (Visited PLMN) that can provide a network slice equivalent to a first network slice of the first PLMN (20). The network node (21) transmits the list to the User Equipment (UE) (1) through the second PLMN (30) in order for the first PLMN(20) to cause the UE(1), which is the HPLMN of the first PLMN, to prefer the at least one VPLMN when selecting the PLMN. This can contribute, for example, to making the UE easily select a VPLMN that can provide a network slice equivalent to a specified network slice of an HPLMN.
