Method and apparatus for transmitting data from a central communication station (104) to a mobile communication device (106) using a pre-selected data protocol if the central communication station (104) cannot initiate data communication with the mobile communication device. The central communication station (104) contacts the mobile communication device (106) in a manner other than the pre-selected data protocol, such as by placing a wireless telephone call to the mobile communication device (106). The mobile communication device (106) contains means for determining the origin of the wireless telephone call (202, 200). If the mobile communication device (106) determines that the wireless telephone call originated from the central communication station (104), data communications are initiated by the mobile communication device (106) to the central communication station (104). Data is then transmitted from the central communication station (104) to the mobile communication device (106).
L'invention concerne un procédé et un appareil de transmission de données d'une station (104) de communication centrale à un dispositif (106) de communication mobile au moyen d'un protocole de données pré-sélectionnées si la station (104) de communication centrale ne peut pas amorcer la transmission de données avec le dispositif de communication mobile. La station (104) de communication centrale contacte le dispositif (106) de communication mobile d'une autre manière que par le biais du protocole de données pré-sélectionnées, telle qu'en passant un appel (202, 200) radiotéléphonique au dispositif (106) de communication mobile. Le dispositif (106) de communication mobile contient des moyens permettant de déterminer l'origine des appels (202, 200) radiotéléphoniques. Si le dispositif (106) de communication mobile détermine que l'appel radiotéléphonique provient de la station (104) de communication centrale, les transmissions de données sont amorcées par le dispositif (106) de communication mobile à la station (104) de communication centrale. Les données sont ensuite transmises par la station (104) de communication centrale au dispositif (106) de communication mobile.
