Message traffic between a communications unit and a first network unit of a mobile radio system, initiated by an SIP control message, is monitored. The SIP control message is evaluated by a second network unit by using at least one analysis parameter and an analysis result is generated therefrom. The analysis result is used for generating at least one item for utilization information of the first network unit that monitors the message traffic between the communications unit and the first network unit.
