Abstract

La présente invention concerne un procédé de configuration et des nœuds prenant en charge une radiomessagerie à porteuses multiples. Le procédé comprend les étapes suivantes : un premier nœud reçoit, sur des porteuses d'ancrage, des informations concernant des porteuses non d'ancrage qui sont diffusées par un second nœud et peuvent être utilisées pour une radiomessagerie; le premier nœud sélectionne une porteuse parmi les porteuses d'ancrage et les porteuses non d'ancrage, ou sélectionne une porteuse parmi les porteuses non d'ancrage; le premier nœud surveille et reçoit, sur la porteuse sélectionnée, un message de radiomessagerie émis par une entité de gestion de mobilité au moyen du second nœud. Si le premier nœud est un équipement d'utilisateur et que le second nœud est une station de base, en configurant, pour l'équipement d'utilisateur, des porteuses non d'ancrage qui peuvent être utilisées pour transmettre un message de radiomessagerie, et en fournissant un procédé de sélection de porteuse de radiomessagerie pour l'équipement d'utilisateur, la présente invention peut abaisser la limite de capacité de radiomessagerie et peut également permettre à l'équipement d'utilisateur d'écouter des messages de radiomessagerie sur chaque porteuse de radiomessagerie de manière relativement équilibrée, de sorte à atteindre l'objectif d'équilibrage de charge.
