Global Standards Collaboration (GSC) 14 DOCUMENT #: GSC 14 -PLEN-046 FOR: Presentation SOURCE: TTA AGENDA ITEM: 6. 1 CONTACT(S): woojaa@keit. re. kr TTA Activities on standardization of Integrated I/O Interface for mobile phones Dr. LEE, Hyeon. Woo Chair of PG 701, TTA Geneva, 13 -16 July 2009 Fostering worldwide interoperability

Highlight of Current Activities New Standard on Integrated I/O Connection Interface for Mobile Phones (Revised in Nov. 2007, certified in Jun. 2008) – To meet the slimming & miniaturizing trend as well as to increase consumer benefits – Estimated cost saving : USD 10 M per year Incumbent Battery Charger 24 pin (Since 2001) USB Data Cable New & Integrated + Earphone 20 pin TV Out Cable Adapter for 24 pin 20 pin is available Fostering worldwide interoperability 2

Proposed Strategic Direction It is very important to have single standardized charger and I/O interface for mobile devices User convenience Resources saving Cost saving for user and vendors Need to encourage the global /regional harmonization of I/O interfaces of IMT mobile devices as well as other mobile/portable devices Charging only Charging and data exchange Charging, data exchange and Audio/Visual connection Etc. 3 Fostering worldwide interoperability

Challenges TTA standard on the integrated I/O connection Interface for Mobile Phones: Already published and widely used commercially in Korea GSMA UCS(Universe changing solution) Plan During MWC ’ 09, UCS initiatives was launched. (Joined by many vendors and operators) Based on Micro USB (Elec. & Mech. Interface), completion by 2012. OMTP (Open Mobile Terminal platform) Published common charging and local data connectivity document V 1. 0 on Feb. 2009 Geneva, 13 -16 July 2009 Fostering worldwide interoperability 4

Challenges IEC-TC 100 (Battery charging interface for small handheld multimedia devices) The draft standard proposal was submitted by Finland as a Fast Track project proposal to the IEC TC 100 in December 2008 China Published 4 pin mobile Phone charger recommendation on 2006 Japan CIAJ started discussion on standard charger interface for mobile phone from June 2008 , targeting completion by end of 2009. Will be based on micro USB Some guideline on Lithum ion battery was published on May 2008. Geneva, 13 -16 July 2009 Fostering worldwide interoperability 5

Next Steps toward integrated I/O connection interface Recognizing – – To maximize user benefits of usingle peripheral device , e. g. Charger, for different devices from different vendors. To minimize the wasting of both costs and resources by customers to reuse one peripheral for several devices. Further collaboration on integrated I/O connection interface standard for mobile Devices 6 - Potential collaboration with other bodies - Forward compatibility with UCS & IEC TC 100 can be considered. Fostering worldwide interoperability
