Nexign Network Repository Function (NRF) is a critical component of the 5G network control plane allowing communications service providers (CSPs) to build a distributed and scalable service-based architecture and enable effective interactions between 5G network functions (NF) through standardized APIs (Service Based Interface).
Nexign NRF follows the standards of the same-name network function described in 3GPP Release 16. The Nexign product registers and stores up-to-date profiles of all NF instances available on the CSP's network. It provides a discovery service for any service consumer looking for a specific service provider in the network and sends notifications to the consumer subscribed for the NF services.
Nexign NRF can function in a stand-alone mode or as part of the integrated Nexign Signaling solution that provides converged signaling traffic management across 3G, 4G and 5G networks.
