ABSTRACT:
A system that processes telecommunications calls from a switch to provide call services. The system supports transactional and conversational protocols. For conversational protocols, call context is maintained at a service control point during call processing. Transactional and conversational messages are mapped to and from a generic message structure to simplify the input and output interfaces of supported service applications. Service control points comprise Communications Servers and Transaction Servers. Communications Servers are coupled by a WAN to provide distributed processing and enhance reliability and load balancing. A method processes conversational protocol messages while maintaining call context at a Communications Server. A method supports multiple-service calls by redirecting processing from one Service Application executing on an original service control point to another Service Application without communicating with the originating switch between services. The other Service Application may execute on a separate service control point coupled to the original service control point by a WAN.
