35、pply. 4 Abstract Test Method (ATM) 4.1 Introduction This clause describes the ATM used to test the Diameter protocol on the Rf/Ro interface at the x-CSCF side and at the charging servers (Rf: CTF/CDF, To: OCF/CTF) side. ETSI ETSI TS 103 374-3 V1.2.1 (2017-01)8 4.2 Test architecture 4.2.1 Test method

36、 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

37、 following figures depict the position of the Rf and Ro reference points within the overall 3GPP online and offline charging architecture.

Figure 2: Logical ubiquitous online charging architecture ETSI ETSI TS 103 374-3 V1.2.1 (2017-01)9 The test method chosen is the remote test method. Re

40、mote 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 as a charging server when the IUT is an x-CSCF. As the exchange between the test system and the IUT is at the diameter message level,

41、the lower layers of the test machine shall be totally conformant with the corresponding lower layers specifications to use the remote test method. 4.2.2 Test machine configuration 4.2.2.1 Test configurations using Rf interface The Rf interface is located between a CTF equipment hosted by an x-CSCF o
