mITF objectives and structure
• Objectives:To realize Future Mobile Communications Systems and Services such as the forth-generation mobile communications systems and mobile commerce services, at an early date by performing research and development activities, making studies on standardization, conducting coordination with related bodies, collecting information, and carrying out promotional and educational activities, and thereby contribute to a healthy utilization of radio spectrum.
• Establishment : June 25, 2001 (Secretariat :ARIB)• Members (as of May, 2004)
- General members : 97 - Individual members : 11 - Special members : 2 (ARIB and TTC)
• Current main activities- Future Mobile Communications Systems (systems beyond IMT-2000)- Mobile Commerce

Conclusions and mITF goal
• mITF has identified necessary features for beyond 3G mobile systems.
• Service platform has an important role as a common basis for realizing such features.
• It is envisaged that future services are being provided by advanced mobile terminals with the cooperation of 4G service platform and a number of service providers.mITF goal is to realize the future mobile communications systems beyond IMT-2000. To achieve this goal, it is strongly required to promote research and development activities in various areas.To facilitate the R&D and standardization in a smooth and efficient manner, it is indispensable for the concerned parties to work closely with one another, so that they can share information and promote R&D and standardization activities.

From an operator’s point of view, the following points should be emphasized
•Reasonable tariff•Reliability and QoS•Provide sufficient security and ensure privacy of users•Should be attractive for service providers as well as users(e.g., Location Platform or Music Downloading Platform)
