Content for TR 23.795 Word version: 16.1.0

1 Scope p. 9

The present document is a technical report which identifies the application architecture aspects to support V2X services, and corresponding architectural solutions. The study includes identifying architecture requirements that are necessary to ensure efficient use and deployment of V2X services over 3GPP systems.

The study takes into consideration 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.

This document will provide recommendations for normative work.

2 References p. 9

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
