Abstract

A telecommunications toll network system employs a central database computer to provide routing and calling rate instructions to toll switches. To allow sponsors of pay services, such as 900 number information services, to control the kinds of calls they receive and the rates charged, the central database computer employs routing plans. These routing plans contain conditional branches selected based on data provided in a query from the originating toll switch (OTS) and sent to the database computer via common channel signaling (CCS). According to embodiments, sponsors can insert objects, called rate nodes, in their routing plans to override the default rate to be applied to the call. Rate nodes are non-branching elements inserted in a routing plan that specify a rate to be used for billing. The rate is specified on the automated message accounting (AMA) record and used by a billing platform to generate bills to the callers.
