  • 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
slide5

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)
