It is envisioned in the future that not only smartphones will connect to cellular networks, but also all kinds of different wearable devices, sensors, vehicles, home appliances, VR headsets, and robots. Because the characteristics of these devices differ largely, people argue that future 5G systems should be designed to elastically accommodate different user types. The evolution of core networks will be driven by integrating heterogeneous networking technologies with the ultimate goal of migrating toward a new form of softwarized and programmable network. Network function virtualization will provide flexibility, short time to market, and low-cost solution to build network services, which are important features of 5G networks. In this talk, I’ll first present the evolution of cellular systems from 1st generation (1G) to 4th generation (4G), with a focus on core networks. I’ll then discuss the softwarization and virtualization of 5G core networks. Finally, I’ll present the open-source projects we have been developing for 5G core networks, including Reconfigurable Core (RECO), Service Level Virtualization (SLV), and free5GC.


Jyh-Cheng Chen has been a Faculty Member with National Chiao Tung University (NCTU), Hsinchu, Taiwan since 2010. Prior to that, he was with Bellcore/Telcordia Technologies in New Jersey, USA, and National Tsing Hua University (NTHU), Hsinchu, Taiwan. He was the Convener of Computer Science Program, Ministry of Science and Technology, Taiwan from 2016-2018. Dr. Chen received numerous awards, including the Outstanding Teaching Awards from both NCTU and NTHU, the Outstanding Research Award from the Ministry of Science and Technology, the Outstanding I. T. Elite Award, Taiwan, the K. T. Li Breakthrough Award from the Institute of Information and Computing Machinery, and the Telcordia CEO Award. He is a Fellow of the IEEE and a Distinguished Member of the ACM. He was a member of the Fellows Evaluation Committee, IEEE Computer Society.
