CRITICAL COMMUNICATION – A DEFINITION

Critical communications encompass unique properties compared to non-critical

Increased Quality of services

Enhanced resilience

06/01/2016

High-grade encryption

Proven interoperability

TETRA

06/01/2016 P3 at CCW 2016 6

The Switching and Management Infrastructure (SwMI) is not part of the standard

TETRA STANDARD INTERFACES

The TETRA standard defines 4 interfaces: V+D AI, DM AI, PEI, ISI

Two TETRA networks communicate over the Inter-System Interface (ISI)

Data terminals can access data services offered by a TETRA network via the Peripheral Equipment Interface (PEI)

Terminals communicate with the infrastructure over the Voice plus Data Air Interface (V+D AI)

Without a connection to the infrastructure, terminals can communicate over the Direct Mode Air Interface (DM AI)

Today, the TETRA Association tests technical and syntactical interoperability

INTEROPERABILITY

There is no single definition of interoperability. Even at ETSI the term has different meanings in different contexts. Interoperability is often classified into four categories

Conformance: Components of a system are compliant with a given standard

(unit tests; usually tests of OSI layers 1 to 3)

Technical Interoperability: Components of a system produced by different manufacturers are able to exchange messages

Syntactical Interoperability: Components of a system produced by different manufacturers use same data formats when exchanging messages

Semantical Interoperability: Humans interpret the meaning of exchanged information in the same way at the man-machine-interfaces of a system

Organisational Interoperability: Organisations are able to exchange meaningful information across infrastructures, geographical regions, language and cultural borders

STATUS QUO AND FUTURE LANDSCAPE

Critical communications and critical apps emerge from different origins to an overall service platform

Consumer smartphones

PMR terminals

The future: critical apps will form the basis for any kind of service

Non-critical apps parallel

to critical apps

Control rooms

Interconnected networks & terminals

Today‘s focus of IOP and security testing

INTEROPERABILITY AND SECURITY – CHANGES

In future, testing needs extension to cover

In the future interoperability and IT-security has to be tested among many more interfaces

Interface between terminal …

… and terminal

… and peripheral equipment

… and infrastructure

… and control room

Terminal’s internal Interfaces

Different components within terminal and terminal’s operating system

Interface between App

… and operating system

… and back-end infrastructure

… and app’s components

… and other parties’ app

06/01/2016 P3 at CCW 2016 11

QUALITY OF SERVICE – CHANGES

Today In the future

In the future Quality of Service (QoS) will need to handle much more resource contention

Air interface & Control room interface

Call performance (group, individual, …)

Speech -delay, -quality and -intelligibility

Short Data Service performance

…

QoS across various levels of the OSI model

Traffic shaping and classification

Overflow detection

Quality of encryption (confidentiality)

Degree of trust (multi-level authentication)

06/01/2016 P3 at CCW 2016 12

Mobile equipment level

NON-CRITICAL TERMINALS AND APPS – STATUS-QUO

Operating system & application level

Non-critical terminals and apps already undergo a decent amount of testing

Global Certification Forum (GCF)

PCS Type Certification Review Board (PTCRB)

Pre- and post-launch field testing

Roaming tests

Power consumption testing

Chipset testing

…

Android Compatibility Test Suite (CTS)

Google Bouncer (Android Market)

TestFlight Beta Testing and iTunes Connect (Apple)

Various anti-virus appliances

End-to-end Quality of Service (E2E QoS) testing forstandardised and OTT services

CRITICAL APPS – FUTURE CHALLENGES

Future challenges

Critical apps will pose new challenges for the near future

Streamline vendors’ and users’ requirements

Unify advanced development methodologies and base technologies into a robust development platform

Develop standards for interoperability and security testing as well as certification among an increasing amount of components

Foster automation of interoperability testing

Cope with many more parties and entities in the field of IT-security and raise IT-security awareness among users, operators and suppliers

Secure the transition of Mission Critical systems from TETRA to LTE

Put appropriate security policies in place to ensure a robust solution, specifically for the interconnection
