33、This clause describes the ATM used to test the Diameter protocol on the S6a 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 + the executable test sui
34、te) shall behave as an MME when the IUT is an HSS and shall behave as an HSS when the IUT is an MME. 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 corresponding lower layers specificatio
35、ns 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 following test architecture figures
36、 the Diameter Agent is not explicitly depicted as it is seen as a transparent message handler for conformance testing purposes. ETSI ETSI TS 103 261-3 V1.2.1 (2015-06)7 4.1.2.1 Test configurations for MME testing The S6a interface is located between HSS and the SUT. Figure 1: Test architecture with
37、MME as SUT 4.1.2.2 Test configurations for HSS testing The S6a interface is located between MME and the SUT. For a number of tests a second S6a interface is used when the TS acts as two separate MMEs. Figure 2: Test architecture with HSS as SUT 4.1.3 Interconnection of TS and SUT 4.1.3.1 MME Role Fi
38、gure 3 shows the interconnection of TS and SUT in terms of signalling message flows. Diameter messages are transferred over the DIAMP port. ETSI ETSI TS 103 261-3 V1.2.1 (2015-06)8 Figure 3: Interconnection for MME role 4.1.3.2 HSS Role Figure 4 shows the interconnection of TS and SUT in terms of si
39、gnalling message flows. Diameter messages are transferred over the DIAM port. Figure 4: Interconnection for HSS role 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 A
40、TS provides Diameter messages and LL primitives. ETSI ETSI TS 103 261-3 V1.2.1 (2015-06)9 5 ATS conventions 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
41、be considered during any later maintenance or further development of the ATS. The ATS conventions contain two clauses, the naming conventions and the implementation conventions. The naming conventions describe the structure of the naming of all ATS elements. The implementation conventions describe t
42、he functional structure of the ATS. 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 described in the test method clause the test tool shall behave as an HSS when the IUT is an MME and shall behav
43、e as an MME when the IUT is an HSS. For that reason the test case preambles and postambles are named as follows: IUT is a HSS (example TC_HSS_UL_01) f_preamble_MME f_postamble_MME NOTE 1: The tester also behaves as a Diameter Client. IUT is a MME (example TC_MME_UL_01) f_preamble_HSS f_postamble_HSS
44、 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 underlying principles: In most cases, identifiers should be prefixed with a short alphabetic string (specified in table 1) indicating the type of T
45、TCN-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 the body of the identifier with an underscore (“_“): EXAMPLE 1: c_sixteen, t_wait_max. Only module names, data type names and module parameter
46、s should begin with an upper-case letter. All other names (i.e. the part of the identifier following the prefix) should 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 fo
47、r this purpose. EXAMPLE 2: f_authenticateUser. Table 1 specifies the naming guidelines for each element of the TTCN-3 language indicating the recommended prefix, suffixes (if any) and capitalization.
