Patent ID: 7002922

Claim:
A communication network specific charging method for data transmission in a communication network in which a plurality of positions are connected to each other through a wide area network, sub-networks are connected to the respective positions through local area networks, and sending of data from terminal stations in the sub-networks or receiving of data in the terminal stations is performed, the method comprising the steps of: performing intermittent sampling measurements, in the local area networks connected to the respective positions, of transmission states of data sent from the local area networks and transmission states of data received in the local area networks; periodically transmitting data of the transmission states subjected to the sampling measurements to a predetermined center connected to the communication network; and deciding an amount of money to be charged to each user who uses the respective sub-networks on the basis of the data of the transmission states transmitted to the center, wherein protocols having the same using purpose of the transmission states are collected into a certain application for management, and the types of applications of the transmission data are decided from the data of the transmission states, to discriminate charging to a sub-network on the sending side from charging to a sub-network on the receiving side on the basis of the decision.
