1. A method for detecting feature interaction between a first Service Control Point (SCP) based feature and a second SCP-based feature in a call processing network, said method comprising the steps of:

  • using relational database models to model originating and terminating basic call models and to tie Transaction Capabilities Application Part (TCAP) messages to the originating and terminating basic call models;

    modeling the first feature and the second feature based on TCAP messages and TCAP call variables wherein the resultant first and second feature models are distinct from said relational database models representing the basic call models;

    determining from said first feature model a set of TCAP message sequences that can occur when executing the first feature and from said second feature model a set of TCAP message sequences that can occur when executing the second feature;

    determining from said first feature model a call variable usage vector for each TCAP message sequence within the set of TCAP message sequences for the first feature and from said second feature model a call variable usage vector for each TCAP message sequence within the set of TCAP message sequences for the second feature, wherein the call variable usage vectors indicate how the corresponding TCAP message sequence uses call variables; and

    detecting feature interaction by comparing, through use of the relational database models representing the basic call models, the call variable usage vectors of the first feature against the call variable usage vectors of the second feature.
