Abstract

L'invention concerne un procédé de communication basé sur un facilitateur de système de communication de groupe (GCSE). Le procédé comprend les étapes suivantes : un serveur d'application industrielle reçoit une demande d'acquisition d'informations de contact envoyée par un serveur d'application GCSE cible ; le serveur d'application industrielle acquiert, d'après un identificateur de demande, des informations de contact, correspondant à l'identificateur de demande, concernant un second terminal ; et le serveur d'application industrielle envoie les informations de contact concernant le second terminal, au serveur d'application GCSE cible.
