    A method for detecting feature interactions in the design of telephone systems using LOTOS (language of temporal ordering specifications) is described. The specification discussed includes call forwarding on a busy line, setting a three-way call, and call waiting. The ways in which a specification of a telephone system involving such features can be constructed in LOTOS and the ways in which LOTOS... View full abstract»

    The problems of defining features, services, and feature interactions in telecommunication systems are discussed. Several ways of classifying feature interactions are surveyed. Existing approaches for solving the feature-interaction problem are reviewed. It is seen that no full approach exists; they are all partial solutions. The approaches are divided into three classes: avoidance, detection, and... View full abstract»

    A method developed to handle service interactions at the specification level in an intelligent network (IN) is discussed. The method uses a template for describing features based on the basic call state model (BCSM) and additional service processing (ASP) states. Potential interactions can be detected if two features have overlapped ASP control ranges with respect to the BCSM or if they have data ... View full abstract»

    A method for detecting interactions among services and service features in communication systems is proposed. The method uses three types of knowledge: knowledge for clarifying and completing the specification of each feature, knowledge for identifying the implicit relationships among the features, and knowledge for detecting the interactions from the extended feature specifications derived from t...

    The role of an object-oriented environment in preventing, detecting, and resolving service interference is discussed, emphasizing detection and resolution. The effect of the introducing a new service in an object-oriented environment can be modeled and analyzed properly, allowing the service designer to resolve interference. A comprehensive example is included to clarify the concepts. The object-o... View full abstract»
