20、 S1AP protocol on the S1-MME interface as specified in ETSI TS 124 301 1 in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 7 and ETSI ETS 300 406 8. The test notation used in the ATS is TTCN-3 (see ETSI ES 201 873-1 9). The following te
21、st specification and design considerations can be found in the body of the present document: the overall test suite structure; the testing architecture; the test methods and port definitions; the test configurations; TTCN styles and conventions; the partial PIXIT pro forma; the modules containing th
22、e TTCN-3 ATS. Annex A provides the Partial Implementation Extra Information for Testing (PIXIT) pro forma. Annex B provides the Abstract Test Suite (ATS) part of the ATS. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or

35、face at the MME side is described in ETSI TS 103 530-2 4, clause 4. ETSI ETSI TS 103 530-3 V1.1.1 (2018-02)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
36、 conventions shall be considered during any later maintenance or further development of the ATS. The 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 guidel
37、ines of the document ETSI ETS 300 406 8 were considered. 5.2 Testing conventions 5.2.1 Test cases Preamble and Postamble As described in the test method clause the test tool shall behave as an eNB that tunnels NAS messages from UEs over eNB encapsulated to the MME. The test case preambles and postam
38、bles are named as follows: IUT is a S1AP with NAS/MME (example TC_NAS_MME_MGR_01) f_S1AP_init 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 (specifi
39、ed 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 name
40、s, 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 chara
41、cter. 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 language indicating the recommended prefix, suffixes (if any) and capitalization.
