Abstract

Equal access to the trigger functionality of the Advanced Intelligent Network (AIN) is accessible to a plurality of service providers offering independent communication services. In response to a trigger event during processing of a call, a switching office sends a query to a mediation point. In the preferred embodiment, the switching office is a telephone office, and the mediation point is an Integrated Service Control Point (ISCP) of a local exchange carrier AIN telephone network. The ISCP may access its own internal data to determine how to process the call, if the call meets certain criteria. Under other criteria, the ISCP acting as a mediator communicates with an alternate carrier'"'"'s remote database via the common channel interoffice signaling (CCIS) network to obtain one or more instructions as to how to process the particular call. The ISCP validates the instructions from the remote database to insure compatibility with the switches or other equipment of the local network. If valid, the ISCP transmits the instruction to the switching office, which uses information in the instruction to process the call.
