The European Telecommunications Standards Institute (ETSI) completed its third interoperability event testing Third Generation Partnership Project (3GPP) mission-critical standards, called MCX Plugtests. The event, which ran from 3 December until 31 January, was the first remote Plugtests event within the MCX Plugtests program.
During the two-month sessions, 1,000 test cases were run between 26 vendors with a 92 percent success rate. More than 150 test sessions were executed between different vendors. The second Plugtests held last year also had a 92 percent success rate.
Equipment tested included mission-critical application servers, mission-critical clients, multicast/broadcast service centers and IP multimedia subsystem (IMS). The remote-only event enabled vendors to connect via virtual private network (VPN) with the ETSI Hub for Integration and Validation at ETSI (HIVE) and test their mission-critical implementations with each other.
TCCA and the European Commission supported the event, and Public Safety Communications Europe (PSCE) and Public Safety Technology Alliance (PSTA) endorsed the testing.
Based on 3GPP Release 14 technical specifications and the test specification ETSI TS 103 564, developed by ETSI during the first two Plugtests, 100 test cases were used for the remote event. The MCX Plugtests program included comprehensive testing of mission-critical push to talk (MCPTT), mission-critical data (MCData) and mission-critical video (MCVideo) — collectively referred to as MCX — including untested test cases from the first two Plugtests.
Plugtests ensure interoperability between implementations and standard compliance help to validate the standards and to accelerate the time to market for mission-critical products. Only standard-based solutions ensure true interoperability.
Participating vendors include ALEA, Armour Communications, Athonet, Beijing Jiaxun Feihong Electrical, Enensys Technologies, Etelm, Expway, Frequentis, Funkwerk Systems, Harris, Indian Institute of Technology-Bombay, Kapsch CarrierCom, Leonardo, MCOP-University of the Basque Country (UPV/EHU), Motorola Solutions, Nemergent Solutions, Nokia, Polaris Networks, Prescom, Samsung Electronics, Softil, Sonim Technologies, Streamwide, TASSTA, and ZTE Caltta.
A full report and the test specification will be made publicly available on the ETSI website. ETSI will provide feedback observations found during the Plugtests to 3GPP working groups for clarification.
The next MCX Plugtests event, a combined remote and face-to-face event, is planned for September in Europe.
“The PSTA mission of fostering and promoting open, best-in-class, standards-based technology for public safety is achieved when the worldwide tech community comes together to participate in open standards testing for 3GPP Release 14 for MCPTT, MCData and MCVideo,” said TJ Kennedy, PSTA executive director. “PSTA will continue to support remote and on-site plug tests to ensure open standards are truly being leveraged. PSTA currently has six very active technical subcommittees focused on MCPTX, LMR to LTE, identity, cybersecurity, mapping and situational awareness.”
