Context-Sensitive Call Control Using Constraints and Rules

Personalisation and context-awareness are fundamental concerns in Telephony. This paper introduces a rule-based system - 4CRULES - which enables context-sensitive call control by the means of feature configuration rules. 4CRULES is interoperable with standard context services and compositional feature architectures. It has been designed to resolve feature interactions, manage conflicting preferences, and mitigate the uncertainty affecting context data. This is achieved through a constraint optimisation model that maximises adherence to user requirements and domain constraints. Experiments on a suite of instances confirm the practicality of the approach and highlight performance- and adherencecritical factors.
