V2X Application Enabler (VAE) Services; Stage 3
The present document specifies the stage 3 protocol and data model for Vs interface between the V2X application specific server and VAE server and VAE-E interface between VAE servers. It provides stage 3 protocol definitions and message flows, and specifies the API for each service offered by the VAE server. The Vs, VAE-E interfaces and the related stage 2 functional requirements are defined in 3GPP TS 23.286 [4].
The stage 2 application layer architecture, functional requirements, procedures and information flows necessary for enabling Vehicle-to-Everything (V2X) are specified in 3GPP TS 23.286 [4].
The common protocol and interface aspects for API definition are specified in clause 5.2 of 3GPP TS 29.122 [27].
