Managing run-time interactions between call-processing features (intelligent networks)

Network service providers continue to require new and different call processing features for their switching systems. Open call processing addresses the limitations of the current feature procurement process by being vendor-independent; i.e. the same call processing model is used for all switching systems and it is required that features be independently installable on a running system. A structure for call processing software that supports open call processing is described. Different approaches to managing call processing features are discussed. The implementation of a simulation model of a feature manager that ties 17 interacting features together into a single feature package is presented.<>
