name: RSC
full_form: Relay Service Code
context: This solution addresses KI #5. This solution provides a mechanism for protecting fields such as the RSC (and PRUK ID) during PC5 link setup for UE-to-Network (U2N) relay when RSC is protected in restricted discovery. In restricted discovery, RSC is protected (i.e., scrambled and/or ciphered) in both discovery model A and B based on the provisioned discovery security parameters (i.e., DUSKs and/or DUCKs). However, the RSC is not protected in subsequent link setup procedure even when it can be protected in a similar way as in the discovery. To ensure this privacy protection in the subsequent link setup procedures, this solution can be optionally enabled by applying the same protection mechanisms to the Remote UE's parameters exchanged in the PC5 link setup message, e.g., RSC (and PRUK ID) if they are transmitted between the Remote UE and the U2N relay. Note that this protection mechanism only applies when the RSC is privacy protected during restricted discovery procedure.
description: The Relay Service Code (RSC) is a parameter used in the context of PC5 link setup for UE-to-Network (U2N) relay, specifically in relation to protecting fields such as RSC during restricted discovery. It is a critical network attribute for operation.
explanation: Based on the provided context from 3GPP TS 33.847, section 6.42.1, RSC is classified as a Parameter due to its role as a specific piece of information used in the PC5 link setup procedure and its relation to protecting fields during restricted discovery.
