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)
