Summary

0007498: Improvement of the reference to related DEN messages for a specific traffic situation within a DEN message

Description

In ETSI EN 302637-3 V1.2.2 (2014-11), the (optional) data frame “referenceDenms” is part of the “roadWorks” à la carte container.
This data frame “referenceDenms” is of general use for infrastructure hazard warning messages using DENM. Hence, it is required to place the data frame in a less specialised container and make it also available for applications not using the “roadWorks” à la carte container.

Steps To Reproduce

Add data frame “referenceDenms” as an optional element to the “situationContainer”, using the same ASN.1 definition as currently
in the “RoadWorksContainerExtended”.
Since the current occurrence in the “roadWorks” container is optional it can be retained without creating immediate interoperability problems,
although we would suggest to promote a consistent use of the data frame in its new position for all applications (including road works)
using the DEN facility layer service.
Hence, we would suggest to at least mark the use of the data frame in the “roadWorks” container as deprecated, or consider to remove the data frame in this container.

Additional Information

ASN.1 extension to the “SituationContainer”:
Add "referenceDenms ReferenceDenms OPTIONAL) into the "SiatuationContainer" as follows:


SituationContainer ::= SEQUENCE {
    informationQuality InformationQuality,
    eventType CauseCode,
    linkedCause CauseCode OPTIONAL,
    eventHistory EventHistory OPTIONAL,
    referenceDenms ReferenceDenms OPTIONAL,
    ...
}
