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
