35、ethod (ATM) 4.1 Introduction This clause describes the ATM used to test ETSI TS 129 229 2. NOTE: In a real operating network the different Diameter nodes would not connect directly to each other. The connection is usually proxied through one or more Diameter Agents. In the following test architectur

36、e figures the Diameter Agent is not explicitly depicted as it is seen as a transparent message handler for conformance testing purposes. ETSI ETSI TS 103 289-3 V2.1.1 (2016-07)8 4.2 Test architecture 4.2.1 Test method The test method chosen is the remote test method. Remote test method means that th

37、e test tool (the test machine + the executable test suite) shall behave as a CSCF when the IUT is an HSS or an SLF and shall behave as an HSS or SLF when the IUT is a CSCF. As the exchange between the test system and the IUT is at the diameter message level, the lower layers of the test machine shal

38、l 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 Cx interface The Cx interface is located between a CSCF and the HSS.

Cx interface (DIAMETER protocol) is located between an HSS and I-CSCF or between

43、between an SLF and I-CSCF or between an SLF and S-CSCF. 4.2.3 Interconnection of TS and SUT 4.2.3.1 HSS Role Figure 7 shows the interconnection of TS and SUT in terms of Diameter message flows. Diameter messages are transferred over the DIAM port. However in case of several Cx interfaces (CF_2Cx and

44、 CF_3Cx) there will be only one test component communicating with the SUT and running the behaviour of all I-CSCF and S-CSCF.
