Abstract

L'invention porte sur un procédé dans lequel une station de base, assistant des porteuses multiples, transmet un message de recherche de personnes. La station de base détermine un premier instant pour la transmission d'informations associées à un service de radiodiffusion à destinations multiples (MBS), et transmet les informations associées à un MBS au premier instant par l'intermédiaire d'une première porteuse. La station de base détermine un second instant pour la transmission d'un message de recherche de personnes à une station mobile, détermine une seconde porteuse pour la transmission du message de recherche de personnes à la station mobile, et transmet le message de recherche de personnes au second instant par l'intermédiaire de la seconde porteuse. Le second instant est différent du premier instant.
