Service Enabler Architecture Layer for Verticals (SEAL); Functional architecture and information flows
The present document specifies the functional architecture for service enabler architecture layer (SEAL) and the procedures, information flows and APIs for each service within SEAL in order to support vertical applications over the 3GPP system. The present document is applicable to vertical applications using E-UTRAN or NR access based on the EPS or 5GS architecture defined in 3GPP TS 23.401 [9], 3GPP TS 23.246 [17], 3GPP TS 23.468 [16], 3GPP TS 23.501 [10], and 3GPP TS 23.247 [39]. To ensure efficient use and deployment of vertical applications over 3GPP systems this specification for SEAL services includes the group management, configuration management, location management, identity management, key management, network resource management, notification management, network slice capability enablement, data delivery and application data analytics enablement.
