Abstract
A system and method of accessing services from end terminals disposed in an integrated telecommunications network having a packet-switched network (PSN) portion such as, for example, a network portion using the Internet Protocol (IP) and a circuit-switched network (CSN) portion such as, for example, a wireless telephony network portion. A generalized service invocation and realization architecture includes one or more call control modules modified to include service-related Detection Points (DPs), a Service Access component or instance that is created when a new DP is encountered, and one or several service proxies which invoke services on behalf of the Service Access component and mediate between the call control modules and services. A common Service Logic Environment is implemented for local services, mobile agent services, and remote services. The PSN portion is preferably realized as a Voice-over-IP (VoIP) network having a gateway connected to the CSN portion.
