Deutsche Telekom and Ericsson have demonstrated a world-first implementation of 5G end-to-end (E2E) enterprise network slicing combining network exposure capabilities for slice-specific service.
Ericsson and Deutsche Telekom validated this capability in a video production use case allowing a video director to adapt their slice service on-demand according to the requirements of different video streams. The demo was conducted on 5G Standalone (SA) end-to-end network slicing infrastructure in Deutsche Telekom’s Bonn lab.

Deutsche Telekom and Ericsson also realized fully automated configuration, provisioning and end-to-end orchestration of the enterprise slicing service order in the proof of concept using a commercial grade 5G SA network provided by Ericsson.

“The groundbreaking integration of network exposure capability into 5G network slicing lays a technical foundation for 5G service innovation,” says Alex Choi, SVP Technology Strategy & Innovation, Deutsche Telekom.

“Standardized network exposure APIs (Application Programmer Interfaces) provide mechanisms which allow third-party authorized applications to monitor and adjust the behavior of such “slices” within the boundaries of their subscribed services,” Erik Ekudden, Group CTO at Ericsson, said.

The Network Exposure Function (NEF) in 5G provides the ability to convert network capabilities and network APIs into special service APIs tailored for specific use cases and associated applications. The service API can make specific network capabilities discoverable and available at the application level as part of a network slice.
