Data processing

A network element configured to perform a method of processing data in a telecommunications network, the network element comprising:

• an input interface configured to receive first and second notifications from first and second Charging Trigger Functions, CTFs, respectively in the telecommunications network, the first and second notifications relating to network resource usage in the telecommunications network, wherein the first and second notifications comprise first and second telecommunications event data respectively, wherein the first and second telecommunications event data both relate to a particular field for an aggregated network resource usage report, and wherein the first telecommunications event data is different from the second telecommunications event data;
• a record handler configured to:
• in response to determining that the first and second notifications relate to the same telecommunications event as each other, aggregate data based on the first and second notifications to generate the aggregated network resource usage report, wherein said aggregating comprises preferentially selecting one of the first and second telecommunications event data over the other of the first and second telecommunications event data and including said preferentially selected one of the first and second telecommunications event data in the particular field of the aggregated network resource usage report;
• and
• use a scalable transformation function to transform the aggregated network resource usage report into a first usage detail report in a first usage detail report format and a second usage detail report in a second, different usage detail report format;
• and
• an output interface configured to output the first and second usage detail reports to at least one recipient system.
