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
N1 (NAS)

Access

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
