METHOD AND APPARATUS FOR PROVIDING ADVICE OF CHARGE PARAMETERS FOR MOBILE RADIO TELEPHONE CALLS

摘要

The present invention employs a control point that administers an Advice of Charge (AoC) service provided to mobile subscribers. The control point is informed of each call involving a mobile station that subscribes to the Advice of Charge service. The control point determines one or more AoC parameters for the call and sends them to switching node currently serving the mobile station. The mobile station receives the AoC parameters from the serving switching node and determines prospective cost associated with the call and displays that cost to the mobile subscriber. Accumulated costs for that call may also be determined and displayed during the call.
