15  Service-based interface representation of the functional model for SEAL services  p. 324

15.1  General  p. 324

The functional models for SEAL services is represented using functional entities and reference points between the functional entities as specified in subclause 6. The vertical applications consume the SEAL services in the form of APIs. Each SEAL service offers these APIs on a service-based interface to all its consumer entities.

15.2  Functional model representation  p. 324

Figure 15.2-1 illustrates the service-based interface representation of the functional model for SEAL services.

The SEAL function(s) exhibit the service-based interfaces which are used for providing and consuming SEAL services. The service APIs are specified for each SEAL function enabled over the service-based interface. The service-based interfaces of specific SEAL services are specified in this document. All the interactions with SEAL are governed based on the reference point interactions of the functional models specified in subclause 6. VAL function represents the functionalities of the VAL server.
The service APIs offered by the SEAL function(s) are published and discovered on the CAPIF core function as specified in TS 23.222.

16  Network slice capability enablement |R17|  p. 325

16.1  General  p. 325

The network slice capability enablement is a SEAL service that offers network slice capability enablement capabilities, such as support for vertical application to slice re-mapping (which can be defined as the mapping of the UEs running a vertical application to different slice), to one or more vertical applications. The NSCE service provides additional functionality and exposes slice capabilities based on 5GS management system services (e.g. MnS services) and 5GS network services (e.g. NEF APIs, NWDAF APIs, NSACF APIs). The detailed specification of NSCE is provided in TS 23.435.
