The present invention relates to a charging method in a contents delivery network (CDN), and more particularly, to a charging method, a charging apparatus, and a charging system for a contents delivery system, capable of more exactly creating charging data by including an additional dedicated charging device for CDN service. To this end, the contents delivery system according to one embodiment of the present invention includes a general charging device for creating charging data record (CDR) for charging by mirroring the use of packets transmitted/received through a session in order to perform charging for the use of the packets transmitted/received through the session connected with a user terminal on a network, for collecting a user data recorder (UDR) corresponding to the session from any one network device for controlling the session over the network, and for creating one charging data by integrating the CDR and the UDR, and a dedicated charging device for requesting one network device, which controls the session over the network, to transmit the UDR of the user terminal corresponding to the session in order to collect the UDR if the CDR is collected with respect to the session connected to the user terminal from a cache controller, and for creating one charging data by integrating the collected CDR and the UDR.
