  • Mobile Phone-to-PC Connectivity Standards Proposed by MCPC
  • January 26, 1999 (TOKYO) -- The Mobile Computing Promotion Consortium (MCPC) has written proposals for standardizing interfaces that enable information to be passed between mobile phones and personal computers.
    The information would include communication status and battery level data, the group said.

    The MCPC is an open industry group comprising 74 mobile phone companies and PC manufacturers.

    The proposals cover features such as wake-on-ring, for powering up a personal computer from a mobile phone, and wake-on-radio, which automatically transfers data from a personal computer as soon as the mobile phone is within the service area, according to the consortium.

    When a mobile phone or personal handy-phone system (PHS) handset with wake-on-ring capability is connected to a communication device such as a PC or personal digital assistant (PDA), an incoming call will automatically awaken the device from a sleep state and enable it to receive data. With wake-on-radio capability, if the PC or PDA is set for data transfer, the data will be sent automatically as soon as the mobile phone or PHS handset is within the service area.

    "Such features will enable people to stow a notebook PC and mobile phone in a carrying bag, and still send and receive email," said Masahiro Hataguchi, an official at the MCPC.

    Also, the MCPC group is developing Mobile TAPI, which adds mobile phone-specific functions to the existing Telephony Application Programming Interface (TAPI) for connecting PCs and phones. Mobile TAPI enables information delineating the strength of the radio signals, battery level and other data to be downloaded to a PC and viewed on the screen.

    Already, these capabilities are possible with connectors in use with mobile phones and PHS handsets, but the PC card used for PC connectivity must conform to these interfaces.

    For this reason, the MCPC will submit its proposed PC card standard to the Japan Electronic Industry Development Association (JEIDA), the organization for PC card standards in Japan, and the Personal Computer Memory Card International Association (PCMCIA).

    As concerns Mobile TAPI, the MCPC will seek its adoption by Microsoft Corp. in the Windows operating system.
