1  ScopeWord‑p. 6

The present document describes the Diameter-based V4 interface between the V2X Control Function and the Home Subscriber Server (HSS) defined for V2X services.
This specification defines the Diameter application for V4 reference point between the V2X Control Function and the HSS. The interactions between the V2X Control Function and the HSS are specified.
The stage 2 description for V2X service features in EPS is specified in TS 23.285.

4  General Description

4.1  Introduction

The V4 reference point between the V2X Control Function and the HSS is defined in the TS 23.285.
This document describes the V4 interface related procedures, message parameters and protocol specifications.
The V4 interface allows the V2X Control Function to retrieve V2X related subscription data in order to authorise access from the UE for V2X services.
