1 Scope
The present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information
for Testing (PIXIT) pro forma for the test specifications for Diameter protocol on the Rf/Ro interface as specified in
ETSI TS 132 260 [1] and ETSI TS 132 299 [2] in compliance with the relevant requirements and in accordance with the
relevant guidance given in ISO/IEC 9646-7 [7] and ETSI ETS 300 406 [8].
The test notation used in the ATS is TTCN-3 (see ETSI ES 201 873-1 [9]).
The following test specification and design considerations can be found in the body of the present document:
• the overall test suite structure;
• the testing architecture;
• the test methods and port definitions;
• the test configurations;
• TTCN styles and conventions;
• the partial PIXIT pro forma;
• the modules containing the TTCN-3 ATS.
Annex A provides the Partial Implementation Extra Information for Testing (PIXIT) Pro forma.
Annex B provides the Abstract Test Suite (ATS) part of the ATS.

4.2 Test architecture
4.2.1 Test method
The Rf and the Ro are reference points from the Charging Trigger Function (CTF) to the Charging Data Function
(CDF) and the Online Charging Function (OCF) respectively, and are intended for the transport of charging events. Rf
is used for offline charging whereas Ro is used for online charging. The following figures depict the position of the Rf
and Ro reference points within the overall 3GPP online and offline charging architecture.

The test method chosen is the remote test method. Remote test method means that the test tool (the test machine + the
executable test suite) shall behave as an x-CSCF when the IUT is a charging server and shall behave
