With increasing demand of applications consumption over mobile networks, more and more application content is transmitted over the mobile networks. Vertical applications have diverse requirements for the application content distribution and delivery. To ease the various data delivery demands for vertical applications, a data delivery enabler is specified in this document. The data delivery service is part of the SEAL services specified in TS 23.434.

The present document specifies the application enabling layer platform architecture, capabilities and services to efficiently support storage and delivery for the application content/data for vertical applications as part of SEAL services specified in TS 23.434. This work 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 and TS 23.501.
