TIERED CHARGING ALTERATION

摘要

A system determines a tiered charging rule with at least one step. Each step defines a quantity entry point and exit point for the step and defines an alteration rule to be applied to charges falling within the step. The system determines a quantity usage range based on usage related to a billing event. The system range intersects each step range with the quantity usage range to determine applicable steps for the quantity usage range. For each applicable step, the system calculates a step charge based on the length of the applicable step range and a base per unit charge rate and applies an alteration to the step charge based on the corresponding alteration rule for the step.

1. A computer readable medium with instructions stored thereon to alter charges for a billing event in a real time charging domain, the altering comprising:
determining a tiered charging rule with at least one step, each step comprising a numerical range defining quantity entry values and exit values, wherein each step corresponds to a rule for charge alteration; determining a quantity usage range corresponding to usage that generates a billing event, wherein the quantity usage range defines starting values and ending values for the usage considered for alteration; intersecting each step with the quantity usage range to determine applicable steps for the quantity usage range; for each applicable step:
calculating a step charge based on a length of the applicable step range and a base per unit charge rate; andapplying an alteration based on the corresponding rule for charge alteration for the step.
