ETSI Symposium onAchieving Interoperability – Best Practices in Standardization2

A test eventOrganized and run by ETSI (as neutral body) in collaboration with industry partnersScope, test infrastructure and test plan based on standardsFeedback to the ETSI technical groupA tool for the ETSI technical group to validate and enhance the quality of their standards

An opportunity for implementersTo validate their understanding of the standardTo test with (many) other real implementationsTo debug their implementation: early bug fixing, saving time

An opportunity for the communityTo promote the technology and the eco systemTo demonstrate end-to-end interoperability

How do we organize a PlugtestsTM event?


A typical a PlugtestsTM event looks like this …


Run test sessions… according to the test sessions calculated by the ETSI Test scheduler

Automatically calculate most efficient test session scheduleOptimize f2f timeEnsure a fair balance of test sessions amongst vendorsMaximize number of vendor combinationsMaximize number of tests run

Record test results… with the ETSI Test Reporting Tool

Record results and provide real‐time statistical view of the resultsPer test, per test group, per configuration, …Detailed results remain private

Daily wrap‐up meetingsTo discuss issues, work arounds, feedback on base spec and test plan

During the PlugtestsTM event


News ReleasePre‐event or post‐event news release News release template for each vendorsend to the media, put online on the ETSI web site, disseminated through ETSI channels and social network

Dissemination of the survey results to all vendorsDuring the Plugtests event a survey is held to gather information about next events , scope, enhancements, …

Technical ReportDescription of event planning, scope, statistical results, feedback on base spec and test plan

Feedback to the appropriate technical committeesPresentation of results at congresses/workshops

After the PlugtestsTM event


Mission Critical Push To Talk

The phrase “mission-critical push-to-talk”” refers to a PTT product functionality that meets the requirements of public safety mission-critical voice communication, which include high availability/reliability, low latency, support for group calls and 1:1 calls, talker identification, device-to-device direct communications, emergency calling, clear audio quality, etc. The term “MCPTT” is now typically used to refer to 3GPP’s “Mission Critical Push to Talk (MCPTT) over LTE” standard, which is part of 3GPP Release 13, finalized in March 2016.


MCPTT Plugtests event 2017


Unique opportunity for implementersTo validate their understanding of the 3GPP Rel‐13 MCPTT features To test with other real implementationsTo debug their prototype implementations (early bug fixing)

Contribute to the standards validation effortPlugtests Result will be used to improve 3GPP Specifications

Support vendors, operators and usersTo promote the standards‐based and interoperable Mission Critical Push To Talk (MCPTT) Service and its eco‐systemTo demonstrate end‐to‐end interoperability

Complemented with conformance testing3GPP RAN5 MCPTT Conformance test cases expected by 2018

Participants


ETSI had developed a test specification with 47 test cases including features like: Group Call, Affiliations and Floor Control.During the Plugtests event, a total of 160 Test Sessions were run: that is, 160 different combinations based on different configurations in Test Scope.More than 900 tests were conducted, with a success rate of 85%. The failed tests give the vendors valuable information to improve their implementations.The final tests of the MCPTT Plugtests event included pre‐arranged and chat mode Group Calls, which involved several MCPTT clients, a Control Room, a LTE cab radio and a TETRA radio.

Summary


Planning for MCPTT Plugtests event 2018


Provisional Planning


When?25 – 29 June 2018

Where?Planned to be hosted by NIST, US (to be confirmed)

Registration opens in January 2018Each participant needs to register

Only companies who have registered participants, can attend the conference calls and access the event WIKI

Upon registration you willreceive a NDA which you need to signed and returnonce NDA is signed we send you the WIKI credentialsAdd you to the Plugtests mailing list [email protected]
