Abstract

The present invention relates to a portable communication device equipped with a screen and a random access memory comprising:

• • means for receiving a data stream through a radio link;
  • means for automatically displaying information from the data stream on said display screen, without any user'"'"'s request, a part of this information being stored in random access memory during a period of time that is longer than the duration of display;
  • means for displaying information from the data stream on said display screen, upon user'"'"'s request, this information being stored in random access memory during the duration of display only. The present invention also relates to a base able to communicate with a portable communication device.

Claims

1-9. -9. (canceled)

10. Portable communication device equipped with a screen and a random access memory comprising:

means for receiving a data stream through a radio link;

means for automatically displaying information from the data stream on said display screen, without any user'"'"'s request, a part of this information being stored in random access memory during a period of time that is longer than the duration of display;

means for displaying information from the data stream on said display screen, upon user'"'"'s request, this information being stored in random access memory during the duration of display only.

11. Portable communication device according to claim 10 comprising means for successively displaying information from the data stream on said screen, without any user'"'"'s request.

12. Portable communication device according to claim 10 comprising means for displaying in parallel, on a split screen, information from a data stream on said screen, without any user'"'"'s request.

13. Portable communication device according to claim 10, wherein the data stream received from the radio link is formatted according to predefined textual and graphical elements.

14. Portable communication device according to claim 13, wherein the data stream received from the radio link is formatted according to two models constituted of predefined textual and graphical elements, a first model for the display of information without any user'"'"'s request and a second model for the display of information upon user request.

15. Base adapted to communicate with a portable communication device, comprising:

means for connecting to a network;

means for receiving data through said network;

means for receiving requests through a radio link;

means for detecting updates of information received through said network;

means for transmitting data through said radio link, without receiving any request, in case of detection of updates of data received through said network;

means for transmitting data through said radio link, upon reception of a request through said radio link;

means for formatting data received through said network, said formatting using predetermined textual and graphical elements.

16. Base adapted to communicate with a portable communication device according to claim 15, wherein the formatting of the data stream, at the level of said base, is carried out according to two models constituted of predefined textual and graphical elements, a first model for the transmission of data without reception of a request and a second model for the transmission of data upon reception of a request.
