An apparatus for enriching data records based on messages monitored on a telecommunications network having an Internet Protocol (IP) portion includes a data record enrichment module (123) for receiving data records from a data record builder (122). The data records include at least a subscriber identifier field and a handset type identifier field and the data enrichment module (123) stores a table mapping subscriber identifiers with the handset type identifiers. When a received data record includes a subscriber identifier and a handset type identifier, the table is updated appropriately and when the received data record includes the subscriber identifier but does not include the handset type identifier, the data record enrichment module (123) checks the table for the handset type identifier mapped to the subscriber identifier and adds the corresponding handset type identifier, if it is present in the table, to the handset type identifier field in the data record. |
