System for automatically providing customer access to alternative telephony service providers

Abstract

A telecommunications network including a plurality of local exchanges or switching systems, each local switch supporting at least one customer line accessed by customer premise equipment (CPE) such as telephone station sets or multimedia stations. The local switches are connected to one another directly and through tandem switches to create the network. A data base is associated with each local exchange, or with a limited number of local exchanges, and is accessed by the local exchange to provide information for controlling the routing of a call. Each data base contains rate information for the service providers offering competitive services. Such rate information includes the service providers' basic rate structures, time of day discounts, group calling plans, usage discounts and the like. The switching system, in response to information provided by the data base, automatically routes the call to the lowest cost service provider based on this rate information. The data base is updated to reflect changes in service provider rates and to record calls made by each customer for purposes of tracking quantity calling discounts or the like and to update the rate information.
