  1. This work was performed under the following financial assistance award 70NANB20H005 from U.S. Department of Commerce, National Institute of Standards and Technology, PSCR MCS TaaSTing 1

  2. Mission Critical Services (MCS) Certification • MCS certification Chicken or the Egg issue • No MCS Testing equipment ó no certification programs ó jeopardized customers confidence ó demand for testing equipment in a “niche market” • Meanwhile… • “MCPTT aligned” • 3GPP ready…. • “Certified in the Plugtest” • Avalailable in –your MCS network- app store • 1st in the certification • Public Safety Grade • How am I supposed to write my RFI/RFQ? • How am I supposed to write my tender response? 2/20

  3. MCS Certification: Why it’s More Important Than Ever • First flagship projects deploying MCS solutions • Std. compliance & interop ó innovation and competition • Avoid vendor lock-in from the very beginning X • More certification needs • Much quicker release cycles than in PMR world • More stakeholders and relationships MCS UE vendor A + All-in-one COTS LTE MCS Client from vendor device to be certified B/C/D SERVICE MCS MCS MCS CLIENT IP OS vs. IP OS CERTIFICATION LTE SCOPE? LTE RF RF CERTIFICATION 3/20 SCOPE

  4. Background: different kind of Testing and Certification • Interoperability • Conformance • Performance • Field test 4/20

  5. Interop and Conformance MESSAGE X: Header1 PASS Header2 x …. Header n Body MESSAGE Y: OK VENDOR A VENDOR B MESSAGE X: MESSAGE X: FAILED Header1 Header1 Header2 Wrong Header2 x Missing Header x …. …. Conformance & Interop Header n Header n Vs Body Body Interop & conformance 5/20

  6. How does conformance certification usually work ? 3GPP RAN5 3GPP Core Test Cases Test Specs RAN5_SIG MCC TF160 Test Equipment TC TTCN3 implementation TC prose specification Certification Program Test Equipment Certified Lab 6/20

  7. MCS Conformance testing: status (2019) • No certified MCS test equipment • RAN5 TS (MCPTT/MCData/MCVideo Rel 14) ongoing • Full TTCN3 completion & verification pending • Users’ demand pushing…. • ….but economy of scale and 5G activity delaying the availability • Early initiatives in certification programs • GCF-TTCA-JTF => MCS WI 7/20
