The present invention relates to a gateway node (20) and a monitoring method of monitoring data exchange between at least two subscribers in a communication network. A coding information indicating at least one of a coding type and rate-adaptation mechanism applied by the at least two subscribers is stored at the gateway node (20), and a copy of exchanged data is processed at said gateway node (20) using the stored coding information. Then, the processed copy of the exchanged data to a monitoring function. Thereby, a delivery function for the moni-tored data can be implemented in a gateway device or node. This leads to a re-duced signaling and processing load and the monitoring function or apparatus does not require any coding information. |
