5G core network, x86 platform, CU and DU separated, centralized deployment and UPF sunken separately deployment, M600 5GC

Short Description:

MoreLink’s M600 5GC is an evolution to splitting architecture based on 4G-EPC, which changes the disadvantages of integral EPC network, such as complex network schema, reliability scheme is difficult to implement, and operation and maintenance difficulties caused by the interweaving of control and user messages, etc.

Product Overview

The M600 5GC is a 5G core network product with independent intellectual property rights developed by MoreLink, which complies with 3GPP protocol to split the 5G core network functions from user plane and control plane. It adopts the Network Function Virtualization (NFV) design philosophy to construct the network in software, modularization, and servitization, which helps the user plane to break away the constraint of centralization to realize flexible deployment.

The M600 5GC mainly includes element modules the User Plane Function (UPF), Access and Mobility Management Function (AMF), Session Management Function (SMF), Authentication Server Function (AUSF), Unified Data Management Function (UDM), Unified Data Repository (UDR), Policy Control Function (PCF), and Charging Function (CHF), as well as Local Maintenance Terminal (LMT) module used for configuration and maintenance. The module structure as below:

Features

-Based on general hardware server to support virtualization; operating in X86 platform physical server, VMware/KVM or virtual container.

-Lightweight: function modularization, the minimum memory requirement for hardware is 16G, satisfying the high throughput requirement of communication basic functions.

-Simple: easy to deploy and maintenance, one-button offline deployment, operation and maintenance based on web.

-Flexible: control plane and user plane separated, the UPF can be deployed in any position independently, and expanding capacity as needed to meet different networking requirements.

Typical Scenarios

MoreLink M600 5GC product supports 5G Option 2 deployment structure. Two deployment methods are recommended based on scenarios. M600 5GC is based on X86 structure with hardware and software decupling. Operators can adopt centralized deployment or UPF sunken deployment according to the application environment. Both the M600 5GC and the user plane product UPF can be deployed on local X86 server, on the private cloud, KVM/VMWare or container.

Centralized Deployment:

The M600 5GC centralized deployment mode is usually used in vertical industrial applications to establish 5G private network, which will provide stable high-speed data access service for 5G terminals and offer extreme 5G connection experience for users. This kind o deployment method can simplify the network structure to facilitate the operating and maintenace, so as to save CAPAX and OPEX.

UPF Sunken Separately Deployment:

M600 5GC is based on CUPS structure, which can be widely used in vertical industrail applications and complied with MEC structure of ETSI standard. It deploys UPF user plane of the M600 5GC near the access network to satisfy the MEC’s requirements in low delay, high reliability and data isolution.
