In a method for correlating charges in a service layer and a network layer, first charging data is determined for a service layer based on content or a service purchased for a user. Second charging data for a network layer is determined based on transmission for the content or service. The first and second charging data, with any respective metadata, are correlated in order to generate a single bill for the user. This bill may be for the transmission as well as the purchase of the content or service. In the correlation, charges for the network layer and/or the service layer may be changed based on the correlation. For example, duplicative charges such as charging for the content and the traffic used to download the content may be correlated and one of the charges may be changed or removed.
