Introduction of IPLOOK 5GC Solution

March 15, 2021 by IPLOOK
IPLOOK, an experienced mobile core network provider, focuses on providing professional wireless mobile core network products and solutions for operators and enterprises. IPLOOK 5GC is one of our mainly developing products, including below NEs: UPF, SMF, AMF, UDM/AUSF , PCF, NSSF, NEF, NRF.

Highly compacted, IPLOOK 5GC can be implemented on small-size servers including low end COTS servers. Moreover, IPLOOK 5GC enables subscribers register for 3G/4G/ 5G networks first, then ensuring a smooth upgrade to 5G for existing 3G/4G subscribers.

User Plane Function(UPF)
High performed and scalable, UPF plays the critical role in the process of data transfer, offering better performance because it is designed to be distributed and virtualized in 5GC. It supports features and capabilities to facilitate the user plane operation in 5GC. 
Single 5GC UPF instance throughput is up to 100 Gbps.


Session Management Function(SMF)
IPLOOK 5GC SMF builds upon the evolution of the IPLOOK SGW solution in the 4G space.
As a fundamental element of the 5G Service-Based Architecture (SBA), SMF is responsible for keeping trace of PDU sessions and QoS Flows in the 5GC for UEs to make sure their states and status are in sync between Network Functions in Control and User Planes.


Access and Mobility Management Function(AMF)
AMF, a control plane function in 5GC, terminates the control plane of different access networks onto the 5G Core Network(5GC) and controls UEs which can access 5GC to exchange traffic with DNs.
The primary tasks of IPLOOK AMF in 5GC include: Registration Management, Connection Management, Reachability Management, Mobility Management and various function relating to security and access management and authorization.

IPLOOK AMF SMF UPF
Unified Data Management(UDM) / Authentication Server Function(AUSF)
As a unified data management center, IPLOOK UDM/AUSF in 5GC can provide operators with converged data management and efficient user data processing capabilities in 2G/3G/4G/5G multiple networking scenarios. 
IPLOOK supports smooth evolution from 4G EPC HSS to 5GC UDM/AUSF, which can seamlessly migrate full user data to cloud-based UDM/AUSF. 
With significant features and cost advantages than traditional products, IPLOOK’ s carrier-grade UDM/AUSF software is flexible and adaptable to the needs of the customer, which is the cost-effective and practical option for both small and large service providers.

Policy Control Function(PCF)
IPLOOK 5GC PCF is a direct evolution of IPLOOK EPC PCRF on the existing CPS Cloud Native Docker container based platform. The new PCF supports all the existing features of the legacy 3G/4G CPS PCRF in addition to new 5G QoS policy and charging control functions and the related 5G signaling interfaces defined for the 5G PCF by the 3GPP standards (eg. N7, N15, N5, Rx, ..).
Through various configuration options, operators will have the flexibility to enable or disable various features, protocols, or interfaces.

Network Slice Selection Function(NSSF)
In 5G era, network slicing is capability and product.
NSSF is a key native capability of 5G that can maximize the performance of communication networks and reduce costs of network construction and operation. It can be used by the AMF (Core Access and Mobility Management Function) to assist with the selection of the Network Slice instances that will serve a particular device.

IPLOOK NSSF
Network Exposure Function(NEF)
Located between the 5G core network (5GC) and external third-party application functionaries (and possibly some internal AFs), NEF is responsible for managing the external open network data. All external applications that want to access the internal data of 5GC must pass through the NEF.
Therefore, IPLOOK 5GC is able to realize friendly connection between network capability and business requirements by opening the network capability to third-party applications with NEF.
The NEF communicates with each NF via a southbound interface through a northbound API that provides AF with access to 5GC data or the use of certain functions. 3GPP interface refers to the southbound interface between the NEF and 5GC network functions, such as the N29 interface between the NEF and SMF, the N30 interface between the NEF and PCF, and so on.  

IPLOOK NEF
Network Repository Function(NRF)
NRF, one of the network functions of the 5G core network(5GC), is the management center of the service-oriented architecture, supporting the service discovery feature and maintenance of NEF information. 
It can receive NF discovery requests from NF instances and provides information about the discovered NF instance (discovered) to another NF instance.
