Abstract
The invention relates to a method for providing a subscriber (SUB1) with information relating to call-charges for telecommunication services associated with a communication link, as well as a call-charge device (CHARGE), a subscriber terminal (TE4) and a service unit for carrying out the method. The call-charge device (CHARGE) receives one or several of the call-metering messages (MP) associated with the communication link and calculates while the communication link is operative, from these messages (MP) the charges (CH) accrued for the communication link. The call-charge device (CHARGE) then associates with the calculated charges (CH) an acoustic signal and generates an electric signal (ES) which corresponds to the associated acoustic signal. The acoustic signal is subsequently conveyed to the subscriber (SUB1) with the help of an electro-acoustic transducer (LS) which is controlled by the electric signal (ES).
