BT Group plc has expanded its core network partnership with Ericsson to enhance 5G Standalone services for UK businesses.

The renewed agreement builds on Ericsson’s dual-mode 5G Core deployment on BT’s Network Cloud and introduces two new capabilities: the Network Slice Selection Function (NSSF) and the Network Exposure Function (NEF). NSSF enables dynamic, real-time management of network slices, allowing traffic to be intelligently redistributed to maintain consistent performance for critical applications. NEF allows businesses and developers to securely access selected network capabilities through standardised APIs, supporting programmable, application-aware connectivity.

BT said the enhancements will help deliver more predictable, secure and flexible 5G services, supporting use cases such as mission-critical healthcare applications and advanced logistics solutions. The upgrade also strengthens BT’s long-standing collaboration with Ericsson across core and radio access networks, positioning the group to meet rising demand for differentiated, API-enabled network services in the UK.
