Cloud Core Resource Controller
Cloud Core Resource Controller is the commercial realization of the 3GPP Network Functions NSSF and NRF.
Cloud Core Resource Controller (CCRC) provides resource control in the network in an automated way, where resources include NFs, NF services and slices, with the purpose to maximize efficiency and reduce OPEX (ease of use, automation) and CAPEX (cost effective network), via an efficient implementation of NSSF and NRF in a single cloud native product allowing easy interworking with EPC and via a number of added-value features beyond 3GPP standard.
NRF supports Service Discovery function. NRF maintains the NF profile of available NF instances and their supported services, which it receives from NFs during registration procedure. 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, and by that it greatly reduces operational costs for operators.
NSSF is defined in 3GPP as the network function responsible to dynamically place a UE on the most suitable slice according to operators defined policies. CCRC provides a policy based realization of NSSF enabling the implementation of the operator policies for network slicing in real time based on NSSF user and network context awareness.
