I you've read the smpp 3.4, sar_msg_ref_num, sar_total_segments and
sar_segment_seqnum are defined as a vaild way to handle concatenation.
In fact many major carriers around the globe use that method to handle
concatenated MO's.
See sections 5.3.22, .23 and .24.
The only drawback is: according to the spec, they cannot coexist with
UDH.

I see. But according to SMS spec any concat should be specified in
the UDH header (?). Why do we try to support it outside the spec and
with a rather "iffy" approach?

Concatenation works, but only if it's done with the UDH parameters.
On SMPP the sar_ optional values could be used as well, but kannel
ignores that afaik.

Hi,
Any background info? Did MO concatenation work so far? If yes
what is wrong now? Any relevant ticket? Does this fix concat for
the case that udh doesn't specify it?

Subject: [PATCH] Fix MO concatenation
Hi,
attached if patch that fixes issue in MO concatenation handling.
Just example:
- First MO with 2 parts (from:123, to:456, reference id in
concat=0, udh=A)
- Second MO also with 2 parts (from:123, to:456, reference id in
concat=0, udh=B)
Now when we receive part 1 from first MO and then part 2 from
second MO we will put them together.
We are not really able to differentiate First MO parts and second
MO parts but we at least able to minimize
possibility to wrong assemble parts when we check whether UDH
(without concatenation info) is the same.
Please check attached patch.
Looking for feedback...
Thanks,
Alexander Malysh
