Abstract
Audio and videoconference technologies make complex coordination processes easier, especially when mobile participants need to synchronize their action in critical environments. The need for an infrastructure providing such a functionality may arise in complex scenarios where an IP network is not available, as for instance in battlefield or other critical environments. This paper describes L-VCONF, an architecture for geo-located conferencing based on a mobile/cellular network (i.e. GPRS, UMTS, WiMax technologies), quick-and-dirty mobile/cellular geolocation, SIP protocol and presence server. Our architecture supports IP audio/videoconferences enriched with geo-located coordination functionalities in complex environments. The approach described in the paper is robust w.r.t. uncertainty while handling location update notification for SIP presence server.
