Our High-Performing Core Network
Fully virtualizable on VMware, K8S, Docker and OpenStack containers
Network Repository Function(NRF)
NRF, one of the network functions of the 5G core network(5GC). It supports the service discovery feature, which receives NF discovery requests from NF instances and provides information about the discovered NF instance (discovered) to another NF instance. Registration information includes NF type, address, service list, etc.
Key Benefits
Support for service discovery features
Perfect compatibility with third-party core network elements
Deployed on X86 COTS server, NFV platform and Cloud
Enabled for centralized or distributed data centers
IPLOOK's 5GC NRF
- The 5GC NRF serves as the central management component within the service-oriented architecture. It provides service discovery functions and maintains NEF information, including availability and supported capabilities.
- The NRF works in coordination with the HTTP Proxy to enable efficient 5G signaling routing. For services without subscriber-number association, routing is performed through the NRF—such as AMF locating and addressing SMF, similar to how DNS operates in 4G networks. For services associated with a subscriber number, routing is handled by the HTTP Proxy—for example, AMF accessing UDM or PCF, and SMF accessing UDM, PCF, or OCS.

FAQ
What is the Network Repository Function (NRF) in 5G Core?
The Network Repository Function (NRF) is a key component of the 5G Core Service-Based Architecture (SBA). It enables network functions to register, discover, and communicate with each other dynamically through standardized APIs.
How Does NRF Work in 5G Networks?
In a 5G Core network, each Network Function (NF) registers its services with the NRF. When another NF needs to communicate, it queries the NRF to discover available services based on real-time status, capability, and availability.
