Hello Rama,

the handling of NULL is described in part7, clause 9.1:

21) Replace all occurrences of NULL type with the following associated TTCN-3 type (note 13):

- type enumerated <identifier> { NULL },
where <identifier> is the ASN.1 Type reference converted according to clause 8.2, if a synonym of the NULL type is defined, or with

- the nested type definition enumerated { NULL } <identifier>,
where <identifier> is the ASN.1 field identifier, if NULL is used within a structured type.





I hope this clarifies the situation.

best regards

Thomas

Subject: Regarding NULL type in ASN.1


Hi ,

I have a query in using a NULL type declared in ASN.1. I am writing a TTCN equivalent template.

How do we represent a NULL type in TTCN3.

TTCN3 Code:

template FailureCauseWithProtErr t_failurecausewithproterr := physicalChannelFailure;

template FailureCauseWithProtErrTrId t_failurecause := {
rrc_TransactionIdentifier := RRC_TRANSACTION_ID,
failureCause := physicalChannelFailure
}


ASN.1 Code :

FailureCauseWithProtErr ::= CHOICE {
configurationUnsupported NULL,
physicalChannelFailure NULL,
incompatibleSimultaneousReconfiguration NULL,
compressedModeRuntimeError TGPSI,
protocolError ProtocolErrorInformation,
cellUpdateOccurred NULL,
invalidConfiguration NULL,
configurationIncomplete NULL,
unsupportedMeasurement NULL,
mbmsSessionAlreadyReceivedCorrectly NULL,
lowerPriorityMBMSService NULL,
spare5 NULL,
spare4 NULL,
spare3 NULL,
spare2 NULL,
spare1 NULL
}

R.Shekar

Hi,

The point is that the only legal value of a TTCN-3 enumerated type with a single enumeration NULL is NULL.

Your example is failing at two points, you have to use {} for an ASN.1 CHOICE value and of course, you have to assign the value of the selected alternative:

template FailureCauseWithProtErr t_failurecausewithproterr := { physicalChannelFailure := NULL }

Dear Shekarr,



it seems that your TTCN-3 environment does not implement the necessary
mapping rules if it says NULL has not been declared. Unfortunately without a
complete overview on configuration and modules (TTCN-3 and ASN.1) it is hard
to assess whether this is a usage error, a configuration problem or a
tooling issue.



Best regards,
Theo Vassiliou

Btw, your second template will not work either as you have not specified the selected alternative.

contact your tool vendor with this problem.

Subject: Regarding NULL type in ASN.1

Hi ,



I have a query in using a NULL type declared in ASN.1. I am writing a TTCN
equivalent template.



How do we represent a NULL type in TTCN3.



TTCN3 Code:



template FailureCauseWithProtErr t_failurecausewithproterr :=
physicalChannelFailure;



template FailureCauseWithProtErrTrId t_failurecause := {
rrc_TransactionIdentifier := RRC_TRANSACTION_ID,
failureCause := physicalChannelFailure
}



ASN.1 Code :



FailureCauseWithProtErr ::= CHOICE {
configurationUnsupported NULL,
physicalChannelFailure NULL,
incompatibleSimultaneousReconfiguration NULL,
compressedModeRuntimeError TGPSI,
protocolError ProtocolErrorInformation,
cellUpdateOccurred NULL,
invalidConfiguration NULL,
configurationIncomplete NULL,
unsupportedMeasurement NULL,
mbmsSessionAlreadyReceivedCorrectly NULL,
lowerPriorityMBMSService NULL,
spare5 NULL,
spare4 NULL,
spare3 NULL,
spare2 NULL,
spare1 NULL
}





Regards,

R.Shekar

Dear Shekar,

It seems that your TTCN-3 tool does not support NULL.

I think you need to contact your tool vendor and ask for support.

A workaround could be to manually define enumerated replacement for NULL
in ASN.1 if this does not work.

Kind regards,
Alexey

Dear all,

as this is not a TTCN-3/ASN.1 issue but turned into a tool discussion
may I propose to terminate the thread here.

Thank you,

Ina
