Abstract

Selon la présente invention, un réseau de télécommunications radiocellulaire fait appel à des messages de multidiffusion pour transmettre des messages de diffusion de cellules de service de messages courts sur le réseau. Ainsi, un message de multidiffusion est envoyé d'un contrôleur de station de base à un groupe de stations de base adressées, qui répond par transmission de messages de diffusion de cellules de service de messages courts sur l'interface radio. Le groupe de multidiffusion destiné à recevoir des demandes de page peut comprendre toutes les stations de base, auquel cas les stations de base doivent pouvoir déterminer si elles sont spécifiquement adressées et doivent répondre par transmission d'un message de diffusion de cellules de service de messages courts.
