Disclosed is a method for charging Internet phone network usage which can impose charges by transmitting charge information obtained by a gateway to a gatekeeper by using a DRQ message. The gateway calculates a call time by using a call connect time and a call release complete time, and transmits charge information including the call time to the gatekeeper by using the DRQ message. The gatekeeper extracts the charge information from the DRQ message, and imposes charges. As a result, when the gateway or gatekeeper itself obtains the charge information and imposes charges, load is not concentrated and a special protocol is not necessary.
