Abstract

L'invention concerne un procédé de réponse adaptée à un télé-avertissement. Il comporte les étapes suivantes : le côté système envoie un message diffusé de télé-avertissement et d’allocation de canal à toutes les stations mobiles par l’intermédiaire d’un canal de diffusion (S10); les stations mobiles analysent le message diffusé de télé-avertissement et d’allocation de canal, et confrontent les informations tirées de l’analyse aux informations qui y sont mémorisées (S20) ; si la confrontation échoue, le message diffusé de télé-avertissement et d’allocation de canal est éliminé (S22); si la confrontation réussit, alors la station mobile détecte si l’appel en question est un appel que la station mobile a activement quitté ; si ce n’est pas le cas, alors la station se joint à l’appel ; dans le cas contraire, le message diffusé de télé-avertissement et d’allocation de canal est éliminé. L'invention concerne également une station mobile appliquant le procédé.
