Patent Images
1. A mobile communication system comprising a plurality of mobile communication terminals connected via a mobile communication network, wherein:
- each of the plurality of mobile communication terminals has a radio external interface for performing communication via a communication network different from said mobile communication network;
data displayed on a display unit in a given mobile communication terminal is transmitted via said radio external interface to another mobile communication terminal at substantially uniform time intervals; and
said data transmitted by the radio external interface is displayed on a particular display unit in said another mobile communication terminal, whereinthe radio external interface may also transmit said data displayed on the display unit in said given mobile communication terminal to said another mobile communication terminal in a communication mode selected among;
a second communication mode, in which whenever data displayed on the display unit are updated, the updated data are obtained and transmitted; and
a third communication mode, in which data displayed on the display unit are obtained and transmitted at any timing.

Abstract
Frame data (letters, images, still images, motion picture images, etc.) displayed on the display unit in a transmitting side portable telephone set 1 are transmitted via a radio terminal interface (such as Bluetooth) to other receiving side portable telephone set 2 to n, and displayed in the display units therein. Thus, the data displayed on the display unit in any given portable telephone set can be displayed and read out with a plurality of other portable telephone sets, so that they can be have substantially as common data.
