35、017-07)7 5 ATS conventions 5.1 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
36、 ATS conventions contain 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 7 were considered. 5.2 Testing conventions 5.2.1 Test cases Pr
37、eamble and Postamble As described in the test method clause the test tool shall behave as an eNB when the IUT is an MME and shall behave as an MME when the IUT is an eNB. For that reason the test case preambles and postambles are named as follows: IUT is an S1AP/eNB (example TC_S1AP_eNB_RAB_01) f_cf
38、_S1AP_eNB_Up f_cf_Down IUT is a S1AP/MME (example TC_S1AP_MME_RAB_01) f_cf_S1AP_MME_Up f_cf_Down 5.3 Naming conventions 5.3.1 General guidelines The naming conventions are based on the following underlying principles: In most cases, identifiers should be prefixed with a short alphabetic string (spec
39、ified 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 the body of the identifier with an underscore (“_“). EXAMPLE 1: c_sixteen, t_wait_max. Only module n
40、ames, 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) should begin with a lower-case letter. The start of second and subsequent words in an identifier should be indicated by capitalizing the first ch
41、aracter. Underscores should not be used for this purpose. EXAMPLE 2: f_send_Location_Reporting_Control. Table 1 specifies the naming guidelines for each element of the TTCN-3 language indicating the recommended prefix, suffixes (if any) and capitalization. ETSI ETSI TS 103 497-3 V1.1.1 (2017-07)8 Ta

46、nterface as defined in ETSI TS 103 497-2 3. 5.3.3 Test case identifiers The test cases have been divided according to the functionalities into several groups. The test case names are built up according to the following scheme. Table 2: TC identifier naming convention scheme Identifier: _ = Test Case
47、: fixed to “TC“ Interface: S1AP = type of IUT: eNB or MME = group RAB E-RAB management MNP Management procedure STP CDMA2000 tunneling etc. = sequential number (01 to 99) NOTE: This naming scheme results into a one-to-one correspondence between the test purpose identifiers as defined in ETSI TS 103
48、497-2 3 and the test case identifiers. The TP identifier of the test case TC_xxx_01 is TP_xxx_01.
