Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
In a cellular telephone system having a bandwidth-on-demand air interface carrying communication command messages and packet transmissions, and using a minimum bandwidth for maintaining a subscriber communication, a method for determining a charge incurred for use of the air interface bandwidth to carry the subscriber communication, comprising the steps of: estimating a total amount of air interface bandwidth used over the course of the subscriber communication; and multiplying the estimated total amount of bandwidth used by a charging rate to identify the charge incurred for the subscriber communication.
Claim 2
Dependent Claim
88 words
In a cellular telephone system having a bandwidth-on-demand air interface carrying communication command messages and packet transmissions, and using a minimum bandwidth for maintaining a subscriber communication, a method for determining a charge incurred for use of the air interface bandwidth to carry the subscriber communication, comprising the steps of: estimating a total amount of air interface bandwidth used over the course of the subscriber communication; and multiplying the estimated total amount of bandwidth used by a charging rate to identify the charge incurred for the subscriber communication.
Claim 3
Dependent Claim
73 words
The method as in claim 1 wherein the step of estimating the total amount of bandwidth used comprises the steps of: measuring a maximum amount of bandwidth used on the air interface for the subscriber communication during each of a plurality of time intervals measured over the course of the subscriber communication; and summing the measured maximum amounts of bandwidth to determine the estimated total amount of bandwidth used by the subscriber communication.
Claim 4
Dependent Claim
45 words
The method as in claim 2 wherein the step of measuring comprises the steps of: making instantaneous measurements of the bandwidth used during each time interval; and selecting a largest one of the measurements as the maximum amount of bandwidth used during the time interval.
Claim 5
Dependent Claim
25 words
The method as in claim 1 wherein the bandwidth-on-demand type air interface operates in accordance with a code division multiple access (CDMA) communications air interface.
Claim 6
Dependent Claim
26 words
