UnionCore uCP

Genew UnionCore unified Control Plane (uCP) consists of EPC and 5GC network elements of control plane, they are MME, GW-C, AMF, SMF, NRF, NSSF, that they are all based on 3GPP standard and ETSI NFV standard, each of them can be solely deployed as standalone VNF or convergently deployed as a unified product but representing multiple responsibilities.
  • UnionCore uCP



Product Architecture

The system architecture of uCP is based on the standard ETSI NFV architecture. The main functional components can be deployed as VNFs on the virtual infrastructure and managed by the cloud platform. The system architecture of uCP is shown in the figure below:

Genew UnionCore uCP is developed based on the idea of atom-level convergence, that means, not only the system is disaggregated into different modules, each module is a totally standalone Virtualized Network Function Component (VNFC) that could be deployed in a VM or Container, but also for both 4G and 5G signaling, are dealt within the unified Mobility Management (MM) module and unified Session Management (SM) module.

Module functions

RDBMemory databaseThe RDB stores the user context with connections, parameters and states or the Network Function parameters. It is based on Redis DB, Redis DB is an opensource memory database with extraordinary performance and fertile functions.
OMUO&MThe OMU is the Operation and Management Unit, provides routine FCAPS maintenance operation.
SBIInterfaceThe SBI deals with the service-based interfaces, especially the HTTP2 layer with load balancing function.
S1APInterfaceThe S1AP deals with the interface between MME and eNB.
NGAPInterfaceThe NGAP deals with the interface between AMF and gNB.
MMServiceThe MM deals with the EPS NAS and 5GS NAS messages and also performs as a load balancer for those signaling.
SPU-MMServiceThe SPU-MM is the service processing unit of MME and AMF, it provides functions of attach/registration, authentication, service request, handover, tracking area update and paging etc.
N4InterfaceThe N4 deals with the interface between SMF and UPF.
SMServiceThe SM deals with the EPS NAS SM messages and 5GS NAS SM messages and also performs as a load balancer for those signaling.
SPU-SMServiceThe SPU-SM is the service processing unit of GW-C and SMF, it provides functions of session management, policy control, QoS management, UE IP management and GW-C/UPF selection etc.
SPU-NRFServiceThe SPU-NRF is the service processing unit of NRF, it provides the registration and discovery functions for other network functions.
SPU-NSSFServiceThe SPU-NSSF is the service processing unit of NSSF, it provides the network slice selection function.
IPUServiceThe IPU is the IP processing unit transmits the signaling and messages with load balance function.
EMSO&MThe EMS consists of NEs’ O&M Agents and a Web Server to provide Browser & Server O&M architecture, and it also includes part of MANO’s functions like NFVO and VNFM. Its name is NuMax Cloud.
