Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).
The purpose of the ProSe relay transaction identity (PRTI) information element is to uniquely identify an authentication and key agreement procedure for 5G ProSe UE-to-network relay or 5G ProSe UE-to-UE relay. The PRTI allows distinguishing up to 254 different bi-directional messages.
The ProSe relay transaction identity information element is coded as shown in figure 9.11.3.88.1 and table 9.11.3.88.1.
