Abstract

L'invention concerne un procédé de traitement d'appel de groupe MCPTT et un dispositif associé. Un équipement utilisateur (UE) dans un groupe MCPTT est situé dans une première région et/ou une seconde région, la première région comprenant un premier serveur MCPTT, et la seconde région comprenant un second serveur MCPTT. Le procédé de traitement d'appel consiste à : acquérir, par un serveur de définition de groupe pour définir le groupe MCPTT, dans un temps non d'appel, des informations de position rapportées par l'UE dans le groupe MCPTT, les informations de position représentant le fait que l'UE est situé dans la première région ou la seconde région ; et sélectionner, par le serveur de définition de groupe, selon les informations de position rapportées par l'UE dans le groupe MCPTT, le premier serveur MCPTT ou le second serveur MCPTT en tant que serveur de commande du groupe MCPTT. Un mode de réalisation de la présente invention accélère un processus d'établissement d'appel.
