What is Interoperability ?

ERTMS CCRC




The current legal background

GSM-R standards were developed based on the ERTMS High Speed Trans

European Network Directive 96/48 and extended with the evolution towards

the Conventional Rail Directive 2001/16 and is currently based on 2008/57

interoperability Directive and the Corrigendum 2011/18.

The basis for assessment of interoperability

GSM-R standards are based on GSM R99 technology and include all

railways specific requirements and a specific additional frequency range.

ETSI specification compliancy

Vendor’s tests cover GSM & GSM-R generic tests in lab, in a standard

configuration aiming at ensuring conformity with ETSI specifications (in particular

with EN 301515 and TS 102 281). These tests do no cover specific operator’s

configuration and features.

Scope

IOT for functional and system testing

IOT tests cover GSM (including GSM - R specific requirements) generic tests, in a multi vendor’s platform standard configuration. They aim to ensure multi vendor subsystems and networks compatibility. IOT tests are usually performed in one or several labs, and can also be performed on live networks, if lab configuration does not allow performing some tests. These tests do no cover specific operator’s configuration and features. Scope

To prove interoperability in a multi - vendor and multi - network environment

Tests results are a prerequisite for the Network’s Assessment .

Vendor’s tests are performed on customer’s lab (if any) and/or vendor’s lab (Factory Acceptance Tests),

with the GSM-R operator configuration. Project specific tests shall be also performed at this stage (including

options or national features, to check that they do not jeopardise interoperability).

Such tests are included in vendor-customer’s contract. Tests are usually performed by the vendor itself, in

presence of the operator.

Acceptance tests are Project specific; they are performed on live customer’s

network, with the GSM-R operator configuration.

Such tests are included in vendor-customer’s contract.

Tests may be performed by the network operator alone, by the vendor in

presence of the operator, or by the actor in charge of network deployment and

operation.

Relevance for network assessment

• Tests results are a prerequisite for the Network’s Assessment

GSM-R Network Assessment Tests Cases

The GSM-R Network Assessment is a prerequisite for putting in operation for the GSM-R

network.

Scope:

• According to EIRENE FRS and SRS relevant requirements for interoperability including the

FTS when needed.

• International roaming on a pilot line : SIM cards and mobiles belonging to another GSM-R

network.

• Will be performed on the Live Network with the final setting parameter


• Tests Cases completion are performed by NoBos that will provide a

recommendation on network assessment following the tests results.

ERTMS CCRC




QoS and performance requirements

For voice and non-safety related data:

• According to EIRENE FRS and SRS relevant requirements based on Test conditions

specification O-2875.

For ETCS related data:

• The basis for such assessment would be based on the EIRENE FRS and SRS relevant MI

requirements and Subset 093 information when finalized, with the corresponding O-2475

test conditions specification.

• Will be performed on the Live Network with the final setting parameters.


• Tests Cases completion are performed by NoBos that will provide a

recommendation on network assessment following the tests results.

Mobile Terminals assessment

FRMTS Workshop

Paris, 4th October 2012




This assessment will be based on test cases, when finalized, for

Voice and non-safety related data:

According to EIRENE FRS and SRS relevant requirements based on

Test conditions specification O-2875.

Whenever necessary, using an initially assessed network for functional

and System requirements.

This assessment will be based on the same principals as

already described for network assessment regarding the various

steps.

FRMTS Workshop

Paris, 4th October 2012




This assessment will be based on the test cases, when finalized, for

ETCS Data Only Radio:

According to EIRENE FRS and SRS relevant requirements based on

Test conditions specification O-2475.

Whenever necessary, using an initially assessed network for functional

and System requirements.

This terminals assessment will be based on the same principals as

already described for network assessment regarding the various

steps.

Conclusion

ERTMS CCRC




Conclusion

The current analysis shows that network and terminals

testing conditions are under finalization.

The Test Cases for network and terminals assessment

are either waiting formal approval or in progress.

The testing conditions allowing for network and

terminals individual characterization is a complex issue,

when the end to end requirements are to be split.

The specification and testing cases of SIM cards as

Interoperability Constituent is not yet addressed.

The roadmap for such a complete definition has to be

finalised and would require additional work and

financing for both network and terminals requirements.
