NTT DoCoMo Formulates New Terminal Specifications to Enable Any OS or Application to be Added

TOKYO, JAPAN, October 31, 2006 --- NTT DoCoMo, Inc. announced today new terminal specifications, developed jointly with Intel Corporation, that will enable mobile phones to be customized with additional desired operating system or application.

The specifications provide an open domain, which is separate from the phone s default domain containing the preinstalled operating system and applications. A controller enables switching between the domains.

The open domain will enable a company, for example, to install an original browser and scheduler, and set an internal security policy for the terminal. Individuals will be able to install their own personalized game software.

The domain controller ensures that switching between domains is always possible, so the user can access the phone s default domain even if a technical problem causes the open domain to freeze. The controller also ensures that call functions are always available, regardless of which domain is active. If a call is received while the open domain is active, the user can easily switch to the default domain to take the call.

DoCoMo and Intel terminal architecture teams worked together on various elements of next generation cellular terminal requirements to come up with this specification document.

DoCoMo will publish the specifications at 3:00 pm Japan Standard Time on November 1 at:
