  • obtaining an acknowledgement (ACK) number included in a hyper text transfer protocol (HTTP) response that corresponds to a HTTP request and is transmitted from a content server to a user terminal as a first parameter;

    obtaining a content-length field value included in the HTTP response as a second parameter;

    obtaining a header length that is calculated from a transmission control protocol (TCP) payload of a first packet of the HTTP response as a third parameter;

    obtaining an ACK number included in an ACK message that corresponds to the HTTP response and is transmitted from the user terminal to the content server as a fourth parameter;

    determining whether or not the fourth parameter is equal to or greater than a fifth parameter that is a sum of the first parameter, the second parameter and the third parameter; and

    generating billing data if the fourth parameter is equal to or greater than the fifth parameter, wherein the header length is generated by calculating an octet size from the beginning of a TCP payload of the first packet of a HTTP response to the first blank line of the first packet.
