Hi,
Can anyone please explain to me the difference between a transaction
and a dialog in TCAP? I also noticed there were transaction ID and
dialog ID.
Thanks,
Daniel

Daniel,
The dialogue portion communicates information used at the application
layer.
The seven layer OSI concept in the contextr of TCAP is described in
my
TCAP implementation project here:

Hi Vance,
Thanks for your reply. So the dialog ID is used in component sublayer
which is based on transaction layer. And the dialog IDs are visible to
TC user, while the transaction IDs are visible to dialog sublayer
(invisible to TC user), right? But does a dialog ID have any mapping
to a transaction ID, e.g., one to one mappings? And in a typical TCAP
call (setup, going stable, then tear down), how many dialogs and
transactions are involved?
I am not a native English speaker so these words make me a little hard
to understand clearly.
Thanks again,
Daniel Han

I usually think the following terms as the same, but it appears they
are not, sometimes, in the signaling world.
session, dialog, transaction, conversation, etc.
Really confusing sometimes! :-(
