Abstract

L'invention concerne un système de communication comprenant : des dispositifs de communication sans fil qui exécutent une détection de position sur la base de signaux GPS ; un serveur qui gère des données d'aide utilisées dans ladite détection de position basée sur des signaux GPS ; et une station de base femtocellule dans un réseau IMS. Ledit réseau IMS comprend des moyens de conversion qui transfèrent des messages entre la station de base femtocellule et le serveur, et qui sont aptes à convertir des messages entre un premier protocole pouvant être exécuté par la station de base femtocellule et un second protocole pouvant être exécuté par le serveur. Si une demande de détection de position est entrée dans la station de base femtocellule depuis un dispositif de communication sans fil qui a passé un appel d'urgence, la station de base femtocellule acquiert les données d'aide susmentionnées par une communication avec le serveur via les moyens de conversion et permet au dispositif de communication sans fil qui a passé l'appel d'urgence d'exécuter une détection de position sur la base d'un signal GPS au moyen des données d'aide.
