Abstract: Systems, methods, apparatuses, and computer program products for creation of a PCS connection between the remote user equipment (UE) and the relay UE. The remote UE may provide its identifier (e.g., a subscription concealed identifier (SUCI)) to the relay UE and the relay UE may forward this identifier to the network so that the network can authenticate the remote UE. The network may check the authorization of using the relay UE and/or for relaying the remote UE (e.g., both the remote UE and the relay UE may be checked for a configuration that permits the relaying). For the authentication and authorization, the access and mobility management function (AMF) associated with the relay UE may forward the messages between the remote UE and the authentication server function (AUSF) of the remote UE. In this way, certain embodiments described herein may address certain security issues related to relaying a remote UE.
