In a telecommunication system wherein both a first layer charging function and a second layer charging function are able to attend to the processing of the charging data of the first layer, there is a risk of the first twice. To ensure that a client is not unnecessarily charged twice for a first layer service, and to ensure that the first layer service will be charged for, the function controlling the second layer charging transmits, to the function controlling the first layer charging function, information ( 303 ) indicating whether the second layer charging function attends to the charging of both layers, and if so, double charging is prevented. |
