Abstract: A computer file is processed at a first network entity (NE). At least part of the file is received from a second NE. Data relating to the received at least part of the file is transmitted to a third NE and: (i) comprises a file name of the file, the file name being transmitted to the third NE before the first NE received at least one other part of the file; and/or (ii) indicates that the first NE is processing the at least part of the file; and/or (iii) indicates that the first NE is in the process of receiving the file. Confirmation data is received from the third NE, confirming that the third NE has received the transmitted data. A file transfer acknowledgment is transmitted to the second NE on the conditions that the first NE (i) has successfully received the file and (ii) has received the confirmation data.

Abstract: Data is processed in a telecommunications network. First and second notifications are received, via an input interface, from first and second Charging Trigger Functions, CTFs, in the telecommunications network. The first and second notifications relate to network resource usage in the telecommunications network. A scalable transformation function is used to transform data derived from the first and second notifications into a first usage detail report in a first detail report format and a second usage detail report in a second, different detail report format. The first and second usage detail reports are output, via an output interface, to at least one recipient system.
