0 Introduction p. 10

Considering vertical-specific applications and edge applications as the major consumers of 3GPP-provided data analytics services, the application enablement layer can play role on the exposure of data analytics services from different 3GPP domains to the vertical/ASP in a unified manner; and on defining, at an overarching layer, value-add application data analytics services which cover stats/predictions for the end-to-end application service.

This technical specification provides procedures for enabling ADAE service over 3GPP networks, while the architecture is defined in TS 23.434.

1 Scope p. 11

The present document specifies the procedures, information flows and APIs necessary for Application Data Analytics Enablement SEAL Service.

2 References p. 11
