The invention relates to a method for data transfer, wherein trigger information (T-CSI) is sent by the subscriber data base (HLR) to the currently competent service network unit (MSSP) and a trigger event (TRE) is stored along with the trigger information in the service network unit (MSSP). In the presence of trigger events, information is directly requested to the service control unit (SCP) by the service network unit (MSSP). Data can thus be requested by the service control unit and supplied to the subscriber or to his or her communications terminal when a connection is being established and once the connection has already been established. According to the invention, information can be directly requested at all times via a predetermined trigger event. The request is not confined to a single interrogation before the connection is established.
