Feature interactions in telecommunications is an active research area. Many approaches to solve the so-called feature interaction problem have been proposed. However, all these approaches consider feature interaction as a somewhat isolated problem, in particular it is not seen in the context of evolving legacy systems and third party features in a deregulated market environment. An exception is the approach by Marples and Magill [MM98, Mar00], which presents an interaction detection mechanism and an essentially manual resolution approach. We develop an automatic resolution approach that can be integrated with Marples and Magill's detection mechanism. We distinguish two key concepts, namely solutions and resolutions. The former are essentially possible behaviours of the system, they are not qualified as desirable or undesirable, the latter are the desirable solutions. Our approach allows for automatic removal of undesired behaviour and selection of the "best" desired behaviour. The correctness, complexity and suitability of our approach are analysed. Two case studies support these more theoretical considerations. Our approach is transferable to other areas, such as quality of service management, and is not restricted to network architectures with a single point of control.
