Subject: [Sigtran] Query regarding Dialogue Id

Hi all,

(a)  The Dialogue Id is a local reference between the TC User and the stack.
The TUA Message Header includes the Dialogue Id as one of its parameters.
Why should the Dialogue Id be transmitted over the link?

(b) Section 3.3.4 Note 1 of the TUA draft says "The Transaction Id parameter
MUST be present in the TCNV message when the message is sent in response to
a TQURY message. The Transaction Id parameter contains the Transaction
Identifier assigned by the remote TC-User"

    EP-A					EP-B (EP- End Point)
		TQURY (Tid = X)
	|---------------------------->|
	|	TCNV (Tid = X)		|
	|<----------------------------|
	|	TCNV (Tid not included) |
	|---------------------------->|

If a TCNV is sent is response to a TCNV, in which case the Transaction Id
may not be included, how will the receiving entity correlate the TCNV to an
ongoing transaction?

(c) Section 3.3.7 TPAB does not contain Transaction Id as part of the
message. How will the receiving end identify for which Transaction the Abort
has been received?

Thanks and Regards,
Sanjeev.
