  • New Standard on Integrated I/O Connection Interface for Mobile Phones (Revised inNov. 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

Adapter for 24pin-20pin is available

Proposed strategic direction
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.


  • 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 V1.0 on Feb. 2009


    Challenges

    • IEC-TC100 (Battery charging interface for small hand-held multimedia devices)

      • The draft standard proposal was submitted by Finland as a Fast Track project proposal to the IEC TC100 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.


    Next steps toward integrated i o connection interface
    Next Steps toward integrated I/O connection interface

    • Recognizing

      • To maximize user benefits of using single 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

      • Potential collaboration with other bodies

      • Forward compatibility with UCS & IEC TC100 can be considered.

    Organization in TTA

    • Mobile Communications Related Project Groups

    • Mobile platform and Service PG(PG703)

      • Established the standard on the integrated 20pins I/O connection Interface for Mobile Phones on Nov. 2007.

        • March 2001 : 1st edition, 24pins (TTAS.KO-06.0028)

        • December 2002 : 3rd edition(revised version), 24pins (TTAS.KO-06.0028/R2)

        • April 2007 2007 : 4th edition, 20pins (TTAS.KO-06.0028/R3)

        • November 2007 : 5th edition(revised version), 20pins (TTAS.KO-06.0028/R4)
