UnionCore uUP

Genew UnionCore unified User Plane (uUP) consists of EPC and 5GC network elements of user plane, they are GGSN, SGW-U, PGW-U, UPF, 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.

Product Architecture

The system architecture of uUP 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 uUP is shown in the figure below:

Genew UnionCore uUP 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 2/3G, 4G and 5G signaling, are dealt within the unified Session Management (SM) module.

Module functions

RDBMemory databaseThe RDB stores the PDP context with flow table, GTP parameters 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.
SMUInterface & ServiceThe SMU is the Session Management Unit, deals with the N4 interface, processes the PFCP message, manages TEID, charging report etc.
SPUServiceThe SPU is the Slow Processing Unit, matches the user packets with PFCP rules, generates the flow table and provides the URR statics etc.
FPUServiceThe FPU the Fast Processing Unit, deals with user packets according to flow table, carries the URR and QoS operations etc.
DPDKServiceThe DPDK is an opensource highly efficient I/O processing unit, it reads or writes user packets from or to NICs.
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.
