The introduction of TAP3 (Transferred Account Procedure) by the GSM Association has enhanced many billing
possibilities for next generation services. It has however also complicated the users
interaction with the TAP file, developed using a variable file format (as compared with
the fixed file format for TAP1, 2 and 2+), based on industry standard encoding rules (ASN1).
Following the introduction of the TAP 3 format came the Rejects and Returns Process, a process whereby
rejected records, which would normally block the processing of the file, are removed and returned to the VPMN
in a RAP file. The RAP file, created by the GSM Association follows the same industry standard of the TAP 3
file, using ASN1 encoding rules. As the RAP file contains records to be
corrected, it is essential that operational personnel are able to read and edit the files to correct them.
The GSM Association has from the beginning recognised the importance that an operator needs to give to implementing
the correct type of fraud measures. Telecommunications fraud is not new and while there are no definitive figures
to show how much fraud costs the GSM industry, the amounts lost are substantial. Roaming fraud is even more difficult
to combat, thus to help ensure
that quicker measures can be taken to tackle roaming fraud a file format called NRTRDE (Near Real Time Roaming Data
Exchange) has been defined by TADIG. This format is also built on the same industry standard using ASN1 encoding rules as the TAP3 and RAP file.
As a result of all three of the above progressions in the GSM industry, the need for a reliable,
easy to use, flexible editor became an absolute necessity for the operations department of any GSM operator.
Thus Xpectis, using the expertise and knowledge that we have in the telecommunications domain have developed
an operations support and testing tool that handles the administrative and management needs of a team that deal with TAP3,
RAP and NRTRDE files. Our product not only gives
the user the possibility to read and search within TAP3, RAP or NRTRDE files, it also allows one to update (with predifinedvalues management),
remove and insert data, to carry out such tasks as advanced remove, copy paste nodes between several files
simultaneously, export of the file to a text of XML file, merge several files into one, create a TAP3 test file, to generate RAP Acknowledgement
