A method and system for detecting and processing armed triggers associated with specific call functions in an intelligent network, using a distributed intelligent network triggering architecture. The complex trigger profile is removed from call processing at the service switching point to a trigger processing server, so that a much simplified and reduced profile can be sent to the service switching point associated with a roaming subscriber, which overcomes the problem of lack of support for long messages within the signalling infrastructure, and the problems associated with wide variation in the capabilities of service switching points. The reduced processing at the service switching point means that the detection points for armed triggers residing therein need only have a minimal triggering capability and a generic trigger for each detection point, and therefore do not need to be upgraded as new triggers are defined or as new criteria are defined for existing triggers at a given detection point. Such upgrades need only be dealt with in the trigger processing server and since the trigger processing server is normally part of the subscriber's home network, it can be upgraded as required to provide the subscriber with much greater consistency of services and features when roaming to other networks.

Distributed intelligent network triggering system

One of the features of the Intelligent Network (IN) is the storage of subscriber profile information at network databases, such as, but not limited to, service control points (SCPs) and Home Location Registers (HLRs.) Such profiles may also be stored at the local switch level, and be made accessible to all other nodes via the signaling network. The present invention extends service logic functionality for a given subscriber to allow for the interaction of subscriber profiles on behalf of a single subscriber, and sharing of data contained in these profiles, to enhance single-ended, single point-of-control services specific to either the calling or called party offered in an Intelligent Network. As such, an enhanced service tailored to both the called and calling parties is made available.
