Method and apparatus for authenticating user equipment in wireless communication system

Abstract

Disclosed herein is a method for authenticating a UE in a wireless communication system, including: receiving, by a relay UE, a direct communication request message from a remote UE; identifying, by the relay UE, authentication for the remote UE based on the direct communication request message; and transmitting, by the relay UE, a direct communication accept message to the remote UE, and the direct communication request message may include at least one of a first unique identifier or a primary authentication-related key ID of the remote UE, and the direct communication accept message may include an indicator indicating whether secondary authentication of a protocol data unit (PDU) session of the relay UE, which the remote UE uses, is pending.
