3 From 1G to 5G 5G Customer expectation, usage & main challenges 5G core network transformation Network Slicing Service-Based Architecture Control and User Plane Separation 5G Open Network Platform

4 1G All Mobile Network Regional solutions AMPS, NMT RadioCom Mobility Analog Voice 4

5 2G All messaging Network Many Standards GSM, D-AMPS, PDC Mobility Digital Voice ISDN Short Message/SMS Low bit rate Data 5

6 3G All Internet Network Universal Standard Two Networks Voice Network Data IP Network Universal Mobility Digital Voice Short Message/SMS High bit rate Data Video (VoD & IPTV) 6

7 4G All IP Network One IP network for Voice, Data & IoT Universal Mobility Voice over LTE (VoIP) Short Message/SMS High bit rate Data Video (VoD & IPTV) IoT 7

8 8 What about 5G?

9 5G will answer customer expectation Coverage Data Rate Connected Objects the customer s expectation is increasing : a high quality connection everywhere (home, transports, rural, ) customers ask for a more affordable basic internet access (50 Mb/s) new usages, like virtual reality or augmented reality, requires very high bit rate > 1Gb/s some objects, like driverless vehicles, drones or robots, call for low latency 1ms low-end, low energy consumption sensors will be massive and should be handled properly

10 THROUGHPUT New usages will emerge 5G is truly going to revolutionize usages 10 Gbps 360 TV&Video Cloud AR/VR in mobility 1 Gbps 100 Mbps 10 Mbps 1 Mbps Industry & Robots 100 Kbps 10 Kbps Sensors 1 Kbps Actuators 100 bps Smart Agriculture Smart City Autonomous Car Remote Operation 10 1 s 100 ms LATENCY 10 ms 1 ms

12 5G is on track First Release 15 and trials by 2018 for deployments from ~ 2020 Standards Reqs. & initial studies Release 14 Launch of RAN technical studies Phase 1 specs Release 15 Phase 2 specs Release 16 Mid 2018: Phase 1 (Release 15) Spectrum Identification of 5G spectrum candidates Above 6Ghz WRC 19 Spectrum release Adoption Demos Large-scale field trials Deployments

13 Main Challenges for 5G 1. How to meet network requirements of 5G services? Network Slicing 2. How to simplify 5G Network Function Interfaces and protocols? Service Based-Architecture 3. How to improve QoS, Policy usage for 5G services? Control and User Plane Separation

14 14 1- Network Slicing

15 How to achieve a perfect network? The One-size-fits-all model is no longer adapted to 5G 5G 4G 15
