Ericsson Cloud Core Resource Controller (CCRC) provides control and optimization of both network function and network slicing resources. It maximizes network efficiency by dynamically selecting network functions and slices, reducing OPEX (ease of use, automation) and CAPEX (cost effective network).

CCRC implements the 3GPP NRF, NSSF and NSACF network functions. CCRC is built using cloud native and Service Based Architecture technologies to deliver a flexible and high resilient software product.

The NRF is the heart of the service-based architecture (SBA) to monitor the status for service consumers and producers and control how to connect them dynamically. NRF removes the need for network configuration every time a new NF is added/removed from the network, or every time NF capacity is updated due to scale-in or scale-out procedures, and by that it greatly reduces...

OUR KEY BENEFITS

Automated networks to reduce network configuration costs

NRF functionality removes the need for network configuration every time a new NF is added/removed from the network , or every time NF capacity is updated due to scale-in or scale-out

Policy based NSSF implemation enables more intelligent Network Slice Instance selection decisions based on slice load, UE information, or closed loops.

Deployment flexibility and efficiency

NSSF Network Slice Instance selection provides a very flexible mechanism for deployment on NFs adapted to customer’s needs (i.e RAN resources allocation, AMF/SMF/UPF selection)

Hierarchical NRF deployment allowing NRF deployed per region or per slice and a central NRF as bridge to support the across Slice, Region, PLMN discovery

Most flexible policy engine. More than 5000 policies without new coding need.

Increased network resilience

NRF supports internal overload protection and load regulation mechanisms, to secure availability under all conditions, as well as implements mechanisms to protect the network from overload.
