What is 3GPP?

�UMTS targeted a universal mobile standard � European Telecommunication Standardization Institute is

limited to European companies

�3G Partnership Project was founded in 1998

�A collaborative agreement between Standards Development Organizations (SDOs) and other bodies� ARIB (Japan), CCSA (China), ETSI (Europe), ATIS (USA), TTA

(Korea), TTC (Japan), TSDSI (India)

�Within scope of Intern. Mobile Telecommunication (IMT) project of Intern. Telecommunication Union (ITU)

�3GPP produces and maintains specifications for: � 2G, 3G, 4G, 5G and corresponding core networks and services

Access Agnostic Design

�The future 5G Core shall be access agnostic � N2/N3 will be generic and not designed for 5G access only

�Clear split between access and core network required � minimize access dependencies in the core network

e.g. idle mode tracking, paging partly moved to radio access

Summary

�5G is a huge ongoing global industry effort

�3GPP is THE standardization organization for 5G

�5G will be specified in multiple phases

�New Radio and 5G Core Network specification is already well advanced – Phase 1 completion mid 2018

�Commercial start of 3GPP compliant 5G networks is expected around 2020

�Successful Satellite groundwork in 3GPP by Thales

�Still huge effort required to take off eventually

�Nomor Research involved in related activities � Nomor Research signed Joint Statement between ESA and

European Space Industry on „Satellite for 5G“ on 20.09.2017
