Hi Anders,
Thanks a lot for the quick response. I tried to check the same with SVN
build
32080 for an outgoing message(RP DATA, MS->N), and wireshark was able to
dissect the RP information as well as the TPDU itself.

Thanks.

Regards,
Rajeev

Hi,
Is there a way to dissect the 3GPP SMS, contained in the message body of
SIP MESSAGE method, as per the 3GPP standard *3GPP TS 24.341*?

A typical example of the MESSAGE from MO (3GPP TS 24.341[Table B.5-1]) is

*MESSAGE sip:sc.home1.net SIP/2.0
Via: SIP/2.0/UDP [5555::aaa:bbb:ccc:ddd]:1357;comp=sigcomp;
branch=z9hG4bKnashds7
Max-Forwards: 70
Route: <sip:pcscf1.visited1.net:7531;lr;comp=sigcomp>, <
sip:orig () scscf1 home1 net <sip%3Aorig () scscf1 home1 net>;lr>
P-Preferred-Identity: "John Doe" <sip:user1_public1 () home1 net<sip%3Auser1_public1 () home1 net>

From: <sip:user1_public1 () home1 net <sip%3Auser1_public1 () home1 net>>;
tag=171828
To: <sip:sc.home1.net.net>
Call-ID: cb03a0s09a2sdfglkj490333
Cseq: 666 MESSAGE
Content-Type: application/vnd.3gpp.sms
Content-Length: (…)*

The payload includes an RP-DATA message (as per 3GPP TS 24.011 [8]). It
includes:
- Address of the originating UE: this field includes the length indicator
only, 3GPP
- Address of the destination SC, which is configured in the UE; and
- RP-User-Data (3GPP TS 23.040 [3]), which includes SMS-SUBMIT as type
indicator.

Regards,
Rajeev
