SERVICE FRAMEWORKS VERTICAL ENABLERS

• Common API Framework (CAPIF) - a unified Northbound API • V2XAPP - Application layer support for V2X services: enables
framework across network/application functions to facilitate a the efficient use and deployment of V2X applications over
harmonized approach for API development within 3GPP. This 3GPP systems including Platooning, Advanced Remote Driving
ensures that there is a single entry point for vertical applications (ToD), and High Definition Maps. The focus of V2XAPP is to
(a.k.a. API invokers) towards the common API aspects (also provide key capabilities such as message distribution, service
called CAPIF APIs) such as onboarding, discovery, authentication continuity, application resource management, and dynamic
and authorization (Refer to 3GPP TS 23.222). group management (Refer to 3GPP TS 23.286)

• Service Enabler Architecture Layer (SEAL) - specifies application • UASAPP - Application layer support for Uncrewed Aerial
plane and signalling plane entities for application-enabling System: specifies application layer capabilities towards UAS
services (e.g. group management, configuration management, applications on the UAV/UAV Controller and the USS/UTM
location management, identity/key management, network systems to leverage 3GPP transport capabilities, including
resource management); that can be reused across vertical support for communication between UAVs within a geographical
applications (Refer to 3GPP TS 23.434). area, QoS provisioning for C2 communication, monitoring of
location deviation, and reporting of UAV events (Refer to 3GPP
• Edge Application Enablement (EDGEAPP) – provides an edge
enabling layer and application architecture for enabling Edge TS 23.255)
Applications on the Edge Data Network, including the exposure • 5GMARCH - Application architecture for MSGin5G Service:
of northbound APIs towards Edge Applications, integration offers 5G messaging communication capabilities for massive
with the 3GPP Network, and to facilitate communication IoT, including point-to-point, application-to-point, group and
between the Application Clients running on the UE and the broadcast messaging, across multiple UE types (Refer to 3GPP
Edge Application Servers deployed on the Edge Data Network TS 23.554).
with capabilities such as service provisioning, rich application
discovery, and service continuity (Refer to 3GPP TS 23.558). • FFAPP - Application layer support for Factories of the Future:
identifies key issues and solutions related to support for TSN
and TSC communications including network/device monitoring,
QoS coordination, group communication, clock synchronization,
and integration with existing operation technologies (Refer to
3GPP TR 23.745)

LOOKING FORWARD…

As we foray into Release 18 (5G-Advanced)
and beyond, the applications hosted on
3GPP networks will be increasingly diverse
and infinite, and the role of SA6 will be to 5G Vertical Applications
identify the right set of application enablement
initiatives to maximize 5G adoption across
existing and new verticals. Slice Capacity Fused Subscriber- Efficient Data
Exposure Location aware API Delivery
To this end, we are seeing both enhancements
to current focus areas in Rel-17 and expansion
to new areas such as network slice capability
exposure, subscriber-aware northbound IoT Capability Rel-18 Application Application
API, application capability exposure for IoT Exposure Enablement Standards Data Analytics
platforms, fused location capability framework,
efficient data delivery for applications,
enablement of application data analytics
enablement, and support for new verticals such NSSF NEF NRF PCF UDM AF
as smart grid. If you want to shape the future Nnssf Nnef Nnef Npcf Nudm Naf
