3GPP
• Purpose of 3GPP is to prepare, approve and maintain globally
applicable Technical specifications and Technical Reports for:
– a 3rd Generation mobile system based on evolved GSM core
network and UTRA
– Further development of radio technologies such as LTE
coupled with evolution of core networkelements such as
Evolved packet Core (EPC)
– continuing evolution of 2nd generation GSM/EDGE radio
access networks (GERAN)

– selected as one of the 4G technologies by ITU-R
– currently working on Rel 11. However, several of the use
cases, requirements and relevant details are ready to start
work on Rel 12 soon

Non-MTC Mobile Data Application Impacts
• Study on use cases & service scenarios on Mobile Data application
• Study on Network inefficiency from Mobile Data application
Copyright 2011 ITRI 工業技術研究院
19
Proximity-based Services
• Use cases and requirements for an operator network controlled
discovery and communications between devices in proximity and
under a 3GPP network coverage
– for, commercial/social use, Network offloading, Public Safety, Integration of
current infrastructure services
• Use cases and service requirements will be studied including
network operator control, authentication, authorization,
accounting and regulatory aspects

ITRI-ICL/K100 - SA1 & SA2
Going Forward…
• Continue to participate and contribute to work items in
SA1 and SA2
– related to M2M and offloading
• Feedback and inputs are welcome
• Collaborate to bring vendor and operator use cases,
requirements and solutions to 3GPP
Copyright 2011 ITRI 工業技術研究院
22
Concluding Thoughts (1/2…)
• 3GPP standards meeting participation has significantly
grown, especially during the recent past
– Vodafone, Ericsson, NSN, Qualcomm, China Mobile, ZTE,
Samsung, LG, NTT Docomo, Panasonic, KPN, Intel, China Unicom,
Interdigital, KDDI, KPN, Sierra Wireless, Verizon Wireless ..……
Copyright 2011 ITRI 工業技術研究院
23
Concluding Thoughts (..2/2)
• Significant benefits to be part of a large global standard
and to get involved in requirements, use cases, design,
solution, and other ongoing work
– very important for interoperable and differentiating product
development
– deeper understanding of Technical specification design details &
philosophy
– global perspective
– ideas contribution into specs, used by companies globally
– wider visibility
– helps better align internal R & D roadmap with global technology
evolution
