| 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.
is an open industry group comprising 74 mobile phone companies and PC
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.
