Content for TR 23.700-34 Word version: 18.1.0
1 Scope p. 7
The present document is a technical report which identifies the application enabling layer platform architecture, capabilities and services to efficiently support distribution, storage and delivery for the application content/data for vertical applications.
The study takes into consideration the existing stage 1 and stage 2 work within 3GPP related to data delivery and 3GPP system user plane aspects specified in TS 22.261, TS 23.501 and TS 23.247.
This document will provide recommendations for normative work.
2 References p. 7
