0  IntroductionWord‑p. 10

In order to ensure efficient use and deployment of V2X applications on 3GPP networks an architecture for V2X application layer consisting of V2X application enabler is specified in this document.
The V2X application enabler capabilities takes into consideration the study in TR 23.795, the existing stage 1 and stage 2 work within 3GPP related to V2X in TS 22.185, TS 22.186 and TS 23.285, as well as V2X application standards defined outside 3GPP (e.g. ETSI, SAE).

1  ScopeWord‑p. 11

The present document specifies the functional architecture, procedures and information flows for V2X application enabler layer. This specification includes the capabilities of the application layer support for V2X services that are necessary to ensure efficient use and deployment of V2X services over 3GPP systems. The VAE capabilities applies to EPS and 5GS.
