A method for charging Internet protocol multimedia communication sessions within a telecommunication system is disclosed. Charging records are generated by a control element in the system with a same correlation identifier for all the charging records produced for a communication session between parties. A multi-sided correlation identifier and a charging information field containing information related to a determined charging plan is passed via session control protocol between control elements. The charging plan information, along with the multi-sided correlation identifier, is propagated between control elements in the system. The multi-sided correlation identifier and selected charging data is included in each charging record generated for the communication session by each control element. The charge for the communication session is calculated on the basis of the selected charging data received by via the charging records including the multi-sided correlation identifier.
