name: RPAUID
full_form: Restricted ProSe Application User ID
context: 1. The UE stores the chosen PC5 ciphering algorithm, Code-Sending Security Parameter and Code-Receiving Security Parameter together with the RSC. Steps 4a-9a refer to Security procedure for Source UE 4a. The Source UE sends a Relay Discovery Key Request message containing the RPAUID, RSC and its PC5 UE security capability to the 5G DDNMF in order to be allowed to monitor for one or more RPAUIDs of UE-to-UE Relay UEs. 5a. The 5G DDNMF of the Source UE sends an authorization request to the ProSe Application Server. If, based on the RPAUID and RSC of Source UE, the RPAUID is allowed to discover at least one of the UE-to-UE Relay RPAUIDs contained in the Application Level Container, the ProSe Application Server returns an authorization response. 6a. If the Authorization Request is authorized in Step5a, and the PLMN ID in the UE-to-UE Relay RPAUID indicates a different PLMN, the 5G DDNMF of the Source UE contacts the indicated PLMN's 5G DDNMF of UE-to-UE Relay by sending a Discovery
description: The Restricted ProSe Application User ID (RPAUID) is a critical network attribute used in the context of ProSe (Proximity Services) for UE-to-UE relay discovery. It is utilized to identify and authorize specific UEs for relay services, ensuring secure communication between them.
explanation: Given its role as an identifier for authorization and security procedures within the ProSe application, RPAUID fits into the 'Parameter' category. The context highlights its use in messages, requests, and responses related to UE-to-UE relay discovery, emphasizing its importance as a parameter in these network operations.
