Rel-17 TS 23.558 defines the application layer architecture to enable edge applications over 3GPP networks. It includes features such as ECS discovery, service provisioning, EAS discovery, EEC/EAS/EES registration, network and Edge Enabler Layer capability exposure, service continuity support with seamless service continuity and EEC context continuity etc. along with cardinality rules, deployment options, involved relationships and mapping with ETSI MEC [3] and GSMA OP [4] architectures. This TR documents a study on architecture and procedure enhancements to improve the Rel-17 architecture for enabling edge applications, and to support emerging industry requirements.

The present document is a technical report capturing the study on enhanced architecture for enabling edge applications over 3GPP networks. The study bases the enhancements on the work done in TS 23.558 and takes into consideration other related work done within and outside 3GPP i.e. ETSI MEC [3] and GSMA OP [4]. The aspects of the study include identifying new key issues, architecture requirements, related architecture enhancements and solutions, cardinality rules, deployment options, and involved entities and relationships to enhance the Rel-17 architecture for enabling edge applications.
