Abstract: A mediation Service Control Point (SCP) capable of communicating Signaling Connection Control Part (SCCP) based signals is interfaced between a plurality of Service Control Points (SCPs) each providing IN services and a Service Switching Point (SSP) serving a particular IN subscriber. In response to a need to utilize an IN service, the serving SSP transmits a query signal to the mediation SCP. The mediation SCP determines which SCP or SCPs are associated with the indicated IN subscriber and accordingly invokes or executes the determined one or more SCPs to provide the needed IN service. As a result, a one-to-one relationship imposed on the serving telecommunications network is relaxed and an IN subscriber is able to utilize IN services by way of multiple SCPs.
