Abstract

A system and method of implementing and provisioning features and thereby providing feature services in a call processing environment where features may be introduced, changed or removed from outside the code base. Features are introduced or 'injected' into the call processing environment using a feature registry. The feature registry is used to manage feature configuration, behavior and interactions. The code base references the feature registry to apply features during operation. In this manner, features can be implemented by reference without modification or rebuilding of the code base. Features can be added, modified or removed without requiring a system upgrade, even while the code base is in operation. The code base uses a structured framework into which features can be introduced by reference using the feature registry. A feature service manager exclusively controls the feature registry and handles provisioning of features. Feature interaction potential is identified and resolved during feature provisioning. The feature service manager can be configured to enforce feature integrity and behavior rules specific to the call processing product being provisioned.
