Abstract

La présente application se rapporte au domaine technique des communications. Un procédé et un appareil de communication sont divulgués. Le procédé comprend les étapes suivantes : une plateforme IdO déterminant N dispositifs terminaux pour un premier service à traiter, et déterminant, à partir des N dispositifs terminaux, P dispositifs terminaux cibles qui prennent en charge une communication en champ proche ; et la plateforme IdO déterminant M dispositifs relais qui prennent en charge le premier service, envoyant un premier message aux M dispositifs relais, et envoyant un second message à des dispositifs terminaux, autres que les P dispositifs terminaux cibles, parmi les N dispositifs terminaux. En utilisant le procédé, la plateforme IdO envoie le premier message aux M dispositifs relais, de sorte que les M dispositifs relais puissent diffuser des informations de service du premier service au moyen d'une communication en champ proche. En ce qui concerne les dispositifs terminaux, autres que les P dispositifs terminaux cibles, parmi les N dispositifs terminaux, la plateforme IdO peut envoyer les informations de service du premier service au moyen d'une diffusion individuelle, garantissant ainsi efficacement que les N dispositifs terminaux puissent tous recevoir efficacement les informations de service du premier service.
