CTI/MTS collaboration - 3GPP TF160 Olivier Genoud (ETSI) MTS#77 23.05.2019

TF160 in a nutshell 3GPP Task Force 160 setup in June 2000. Supporting & under responsibility of 3GPP RAN WG5 (RAN5): Mobile Terminal Conformance Testing. Translates the 3GPP conformance test cases from prose (test specification) into a reference implementation. Implementation done using TTCN-2 for 3G (up to Release 9), Implementation done using TTCN-3 for 3G (from Release 10) and 4G. Develops and maintains a set of 25 TTCN-2 & 20 TTCN-3 test suites (over 4000 test cases). Latest news: 5G project: started mid-2017, ramping up rapidly, 5G test cases implemented in TTCN-3, first 5G test cases executed on test platforms and passing against real 5G devices, expected to be a long-term project. Baseline: will need to be partly upgraded for Standalone NR/5GC (NAS changes).

TF160 usage of MTS ‘outputs’ TTCN-3 Standard: Used formally by TF160 since 2008. Current usage of standardized mappings for language imports: ASN.1, XML. TTCN-3 Tool Vendors: Strong support, currently 3GPP TTCN-3 test suites analysed by TF160 against 5 different TTCN-3 tools. Return on experience: TTCN-3 standard (and tools) very stable. Occasional Change Requests raised. Main area where issues are currently found: XML mapping & handling by tools. Baseline: will need to be partly upgraded for Standalone NR/5GC (NAS changes).

To continue: TF160 expectations on MTS the maintenance and evolution of the TTCN-3 standard. Change Requests resolution. the maintenance and extension of conformance tests for TTCN-3 tools: With special focus on XML conformance. Baseline: will need to be partly upgraded for Standalone NR/5GC (NAS changes).
