1 Scope p. 8

The scope of this Technical Report is to study and evaluate the possible architecture enhancements to the Proximity-based Services (ProSe) system defined in TS 23.303, based on the relevant Stage 1 requirements defined in TS 22.278 and TS 22.115.

The present Technical Report documents the analysis and general principles agreed regarding these objectives, and collects the solution details developed based on these agreements, in order to progress them to the relevant specifications.
