This paper presents an approach based on wireless Web and dialogue system convergence for multimodal, multimedia communication services over converged networks. It uses a unique event-triggered service delivery method that separates service interaction and wirelessWeb-based service delivery. Our approach results in an architecture of WAP-based, location-independent, wireless service monitoring, notification and service access for mobile users that can be applied over various network bearers in enterprise environment. A new wireless secure server (WSS) provides secure connections to dialogue systems. It allows one-key switching to retrieve the multimedia content. A prototype system was implemented and performance advantages were demonstrated on several enterprise service applications.
