33、TM) 4.0 Introduction This clause describes the ATM used to test the Diameter protocol on the S9 interface at the MME side and at the HSS side. 4.1 Test architecture 4.1.1 Test method The test method chosen is the remote test method. Remote test method means that the test tool (the test machine and t

34、he executable test suite) shall behave as an H-PCRF when the IUT is a V-PCRF and shall behave as a V-PCRF when the IUT is an H-PCRF. As the exchange between the test system and the IUT is at the diameter message level, the lower layers of the test machine shall be totally conformant with the corresp

35、onding lower layers specifications to use the remote test method. 4.1.2 Test machine configuration 4.1.2.0 Introduction 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 fol

36、lowing test architecture figures the Diameter Agent is not explicitly depicted as it is seen as a transparent message handler for conformance testing purposes. ETSI ETSI TS 103 262-3 V1.2.1 (2015-07)7 4.1.2.1 Test configurations for H-PCRF testing The S9 interface is located between Test System acti

37、ng as V-PCRF and the H-PCRF SUT. Figure 1: Test architecture with H-PCRF as SUT 4.1.2.2 Test configurations for V-PCRF testing The S9 interface is located between Test System acting as H-PCRF and the V-PCRF SUT.

Diameter messages are transferred over the DIAMP port. Some V-P

40、CRF tests may require additional triggering via the Gx or Gxx ports. The configuration can be enabled or disabled by using PIXIT parameters “Gxsupport“ and “Gxxsupport“.

41、interfaces ETSI ETSI TS 103 262-3 V1.2.1 (2015-07)10 4.1.3.3 Test Adapter For execution of the tests the Test Adapter (TA) shall be developed. There are two possibilities to communicate over TA: ATS provides only Diameter messages; or ATS provides Diameter messages and LL primitives. 5 ATS conventio

42、ns 5.0 Introduction The ATS conventions are intended to give a better understanding of the ATS but they also describe the conventions made for the development of the ATS. These conventions shall be considered during any later maintenance or further development of the ATS. The ATS conventions contain

43、 two clauses, the testing conventions and the naming conventions. The naming conventions describe the structure of the naming of all ATS elements. To define the ATS, the guidelines of the document ETSI ETS 300 406 6 were considered. 5.1 Testing conventions 5.1.1 Test cases Preamble and Postamble As

44、described in the test method clause the test tool shall behave as an H-PCRF when the IUT is a V-PCRF and shall behave as a V_PCRF when the IUT is an H-PCRF. For that reason the test case preambles and postambles are named as follows: IUT is a H-PCRF (example TC_HPCRF_HSE_01) f_preamble_VPCRF f_posta

45、mble_VPCRF NOTE 1: The tester also behaves as a Diameter Client. IUT is a V-PCRF (example TC_VPCRF_HSE_01) f_preamble_HPCRF f_postamble_HPCRF NOTE 2: The tester also behaves as a Diameter Server. 5.2 Naming conventions 5.2.1 General guidelines The naming conventions are based on the following underl

46、ying principles: In most cases, identifiers should be prefixed with a short alphabetic string (specified in table 1) indicating the type of TTCN-3 element it represents. Suffixes should not be used except in those specific cases identified in table 2. Prefixes and suffixes should be separated from t

47、he body of the identifier with an underscore (“_“): EXAMPLE 1: c_sixteen, t_wait_max. ETSI ETSI TS 103 262-3 V1.2.1 (2015-07)11 Only module names, data type names and module parameters should begin with an upper-case letter. All other names (i.e. the part of the identifier following the prefix) shou

48、ld begin with a lower-case letter. The start of second and subsequent words in an identifier should be indicated by capitalizing the first character. Underscores should not be used for this purpose. EXAMPLE 2: f_authenticateUser. Table 1 specifies the naming guidelines for each element of the TTCN-3

49、 language indicating the recommended prefix, suffixes (if any) and capitalization. Table 1: TTCN-3 naming convention Language element Naming convention Prefix Suffix Example Notes Module Use upper-case initial letter DiameterS9_ none DiameterS9_Steps TSS grouping Use all upper-case letters none none TP_PCEFRole_IPSMessage template Use lower-case initial letter m_ none m_authApplicationId Message template with wildcard or matching expression Use lower-case initial letters mw_ none mw_subscriptionId Por
