Our work

We inform, advise and have a strong influence on the direction of the industry.

We catalyse and drive the evolution of LTE towards becoming a truly critical communications-grade bearer.

We facilitate the maintenance, development and enhancement of the ETSI TETRA standard, and manage the interoperability process.


How to Test & Certify Mission Critical Products?

Why certification?

• Mission Critical services must be reliable(lives can depend on it)

• Products (Devices, Applications and Servers)need to interoperate with each other:

• Multi-vendor

• Multi-operator

• Multi-service provider

• Certification of Compliance to Standardsis a key-way of achieving interoperability

• Reduce deployment costs and time to market

10

Types of Testing

• Conformance Testing• to ensure the Implementation under Test

conforms to the 3GPP Standard

• Interoperability Testing• to ensure that two or more Implementations under Test

interoperate (work together)

• Performance Testing• to ensure that Implementation(s) under Test meet

Key Performance Indicators (KPI)• e.g. Call Setup Delay, Voice Latency, Voice Quality, Battery Life, etc.

What do we currently have?

3GPP RAN5 Test Cases (3GPP TS 36.579-X)for MCPTT, MCVideo, MCData (not verified)

GCF Work Item for MCPTT (not activated)

ETSI MCX Plugtests(no certification)

ETSI Plugtests Test Cases (ETSI 103 564)141 Test Cases + Observer Scenarios

Test Equipment(LTE Simulator)

Test Equipment(IP Simulator)

Implementation under Test:1) Device + Client

2) Client (for initial testing)TTCN3 Code, developed by 3GPP TF160 (not validated)

Certified Product (not yet)

Why partner with GCF?

• GCF is the mobile industry’s certification solution

• 20-year track record

• Industry wide membership

• Long established systems and processes

• Benefit from economies of scale

• Not only MCX that needs to be complianceassessed but also the underlying LTE stack

• Openness to learn from and benefit each other

GCF-TCCA Joint Taskforce• Goals• Achievements


Copyright GCF 2020

GCF-TCCA Joint Taskforce

15

• Established January 2020 to run for 6 months.

• ‘Develop a staged approach to the development of mission critical certification based on prioritizing industry requirements.’

• Objectives• Determine certification scope.• Determine certification processes.• Determine management and governance model

going forward.

• 8 meetings held• 1 physical meeting (Cambridge, UK)• Around 40 delegates per meeting.• 85 representatives from 39 organisations

MCX Gap Analysis

17

• MCX ‘Gap Analysis’ created to help develop and prioritize the ’certification scope’.

• Living document that• Tracks deployments and bands.• Tracks MCX core and test specification

standards evolution.• Tracks and prioritizes MCX features

based on JTF delegates’ inputs.

• The document will continue to be used by the industry to prioritize future phases of MCX certification.

Certification scope

18

Scope of (GCF) Mission Critical Certification for devices with integrated MCX client apps

Device (3GPP stack)

Device(3GPP stack)

Short Term Long Term

MCX ClientMCX Client(Limited Testing)

• Device certification only (in first phase)• MCX feature assessed as part of

overall GCF device certification.

• Certification will be conducted under GCF rules and processes.• Must be a GCF member to certify.• Certification test must be

conducted by a GCF Recognized Test Organization (RTO).

• Limited MCX feature set that focuses on key features in use today.

• 3GPP Release 15 onwards.

High Level Scope Phase 1 MCPTT Features

19

• Registration• mission critical bearer setup, user

authentication, service authorisation, key retrieval, user profile and group configuration

• Group Call• pre-arranged & chat, on demand, Floor

Control, Priorities• Emergency Group Call• Imminent Peril Group Call

*All communication encrypted

• Private Call• on demand, manual and automatic

commencement mode, with and without floor control

• Affiliation• from user & dispatcher

• Location• Ambience Listening Call

• Short Data Service (SDS) - MCDATA• Enhanced Status – MCDATA

How will MCX devices be certification tested?

20

• LTE (Radio, signaling protocols)• Conformance testing (Network simulator)• Interoperability testing• Live network Field Trials

• Integrated MCX app• Field Trials.

• GCF and TCCA are working with GSMA’s Field Trial Development Group to define field trial test cases for MCX phase 1 GCF Certification.


Conclusions and Next Steps

Mission Critical Agreement Group

GCF has established a new working group:

Mission Critical Agreement Group (MCAG)

• Will take over the initiated work from the GCF-TCCA Joint Task Force

• Continue ongoing development of mission critical certification

• Will manage and prioritize certification for future phases

• Open to all GCF and TCCA members

End to End Certification

Future work of MCAG may include:

• Additional MCX Features

• which are not included in phase 1 yet

• Additional Interfaces and Products, e.g:

• Standalone MCX client certification

• MCX server certification

• Assessing Interworking to legacy systems (TETRA, P25, …)

• Integration of new testing processes

• e.g. lab-based conformance testing

• when test equipment is commercially available

23

TETRA P25

Summary

• GCF and TCCA have partnered to advance Mission Critical certification

• The GCF-TCCA Joint Taskforce has now concluded its work leading to an agreement on how and what to certify in a first phase:

• LTE devices with integrated MCX clients

• Assessed under GCF rules

• Working with GSMA to define TS.11 Field Trial test cases for MCX features

• Mission Critical Agreement Group (MCAG) has been established as a permanent GCF group to manage and develop MC certification going forward.
