Method for charging Internet protocol multimedia communication sessions within a telecommunication system, when charging records, related to communication session charging, are generated by at least one network element, with a same correlation identifier ID for all the charging records produced for a same communication session. It implies the following steps: passing, by means of a session control protocol, a correlation identifier (MSCID) together with a charging information field (CIF) containing information related to a determined charging plan, for a multimedia communication session involving several control elements, from one of these control elements to the others; propagating charging plan information, with the correlation identifier corresponding to at least a selected set of charging data with the correlation identifier for a multimedia communication session between control elements in a network and/or with control elements of other transport or application network layers, involved in the session; including the correlation identifier and selected charging data in each charging record generated for the communication session by each control element which cooperates to the charging of the communication session, and calculating the charging for the communication session on the basis of the selected charging data received by means of the charging records including the correlation identifier. <IMAGE>
