A system and method that transmits and displays graphical images among wireless devices in a push-to-talk system. A predefined set of graphical images is stored in a wireless device, and when a user presses a push-to-talk button on the wireless device, the wireless device displays a list of predefined images to the user to select. After the user selects an image, the wireless device transmits an image code associated with the selected image to a server for relaying to every wireless device in a push-to-talk communication group. When a receiving wireless device receives the image code, it retrieves an image corresponding to the image code from the predefined set and displays the image to the user of the wireless device.

L'invention concerne un système et un procédé permettant d'émettre et d'afficher des images graphiques entre un groupe de dispositifs sans fil, dans un système à bouton de microphone. Un ensemble prédéfini d'images graphiques et stocké dans un dispositif sans fil. Lorsque l'utilisateur appuie sur le bouton de conversation du dispositif sans fil, ce dernier affiche une liste d'images prédéfinies à l'intention de l'utilisateur pour sélection. Lorsque l'utilisateur sélectionne une image, le dispositif sans fil transmet un code d'image associé à l'image sélectionnée à un serveur pour que celui-ci la relaye à chacun des dispositifs sans fil. Lorsqu'un dispositif sans fil de réception reçoit le code d'image, il extrait de l'ensemble prédéfini une image correspondant au code d'image, et affiche l'image pour l'utilisateur du dispositif sans fil.
