Communications service billing based on bandwidth use

Abstract

In a bandwidth-on-demand type communications system, like that provided with a code division multiple access (CDMA) cellular communications system, charging subscribers for calls based on communications length provides an inaccurate measure of communication cost, and further serves to discourage use of the system for data transmission applications. To provide a more accurate cost determination, the amount of bandwidth used by each communication is metered and multiplied by a charging rate. In particular, measurements of the maximum amount of bandwidth used during predetermined time intervals are made during the course of each communication, with the maximum bandwidth measurements being summed to determine an estimate of the total amount of bandwidth used during the communication. The charge for the communication is then determined by multiplying the estimated total bandwidth measurement by a charging rate multiplier.
