Packet Core

Virtual &

Distributed

Key factors in 5G

▪ RAN evolution:

new FQ, massiveMIMO

▪ Core evolution:

virtualization and

distributed HW

5G is of course new features and abbreviations also

4

▪ URLLC - Ultra Reliable Low Latency Connection

▪ MEC - Mobile Edge Computing

Example:

Video streaming and picture recognition is wise to do at the network edge not via Packet Core elements

Core evolution:4G (Evolved Packet Core) => 5G (Virtual (Core) Network Functions)

5

▪ CUPS = Control and User Plane Separation (in e.g. 4G and 5G NSA)

▪ VNF = Virtual Network Functions (in e.g. 5G SA)

For security and charging: Authentication, Policy control, etc.

IoT devices actual + forecast

6

▪ World population about 7,8 Mrd

▪ Access to Internet 1995: 0,04% and 2019: 53,6% (Source: ITU)

Billions (Source: Statista)

3GPP IoT connections about 3,7 Billion

+ WiFi + ZigBee + BT + etc => currently about 10 Billion

Congratulations — it’s (digital) twins!

Driving trends:

▪ Number of IoT devices will increase drastically

▪ Communication networks will have huge amount of capacity

▪ Computing power is available on site + remotely

▪ Maintenance – even in zero touch mode (with AI Artifical Intelligence)

▪ TOP 10 companies (in USA):

Production, raw materials, distribution => Digital services and platforms

▪ Communication networks is a key asset for current economical functions and wellbeing

Technology adoption pace

▪ Technology (and application) adoption pace is much quicker nowadays

▪ On mobile platform there is some billion potential customers instantly

5G will increase data usage per SIM

11

▪ It was 5G that started the unlimited boom in Korea. And people are clearly ready to pay much more for an unlimited experience – but they will also use much more data. A 5G customer is, roughly speaking, using three times more data than a 4G customer – but they also pay 50% more.
