METHOD FOR CALCULATING COMMUNICATION CHARGE, APPARATUS FOR CALCULATING COMMUNICATION CHARGE AND METHOD FOR CHARGING COMMUNICATION

摘要

A method for calculating communication charge in which the IP address of the communication party is identified by analyzing the flow information on the communication the user has performed, and the charge corresponding to the communication that the user has performed is calculated in a discount form if the IP address of the communication party is an IP address registered previously by the user. When the party is registered in the group of the user, the communication charge of the user is calculated at the discount rate different from a standard communication charge rate. The user can be charged according to an individual charging system by not applying to the user a uniform usage-based charging proportional to the amount of data communicated by the user but applying a discount charging system in which the communication charge is discounted depending on the amount of communication between the user and the communication party. Furthermore, a variety of flexible charging services can be provided by performing such a discount depending on the communication party.
