Hi!

Could someone please help me parsing the service center number, the sender number and the date out of this pdu:

730604ae8d01bf02056a81093930343633360057696c6c6b6f6d6d656e207a756d207072616b7469 7363687374656e2047757473636865696e20616c6c6572205a656974656e21204469652041312047 757473636865696e20426f7820697374206b6f7374656e6c6f7320756e6420536965207370617265 6e2062617265732047656c642e204c6f7320676568742773206175660045c60d0361316775747363 6865696e626f782e61742f00081183000ac3072010041307364110c304201009080183070101

i allready decoded the message and the link according to this post http://support.nowsms.com/discus/messages/1/395.html, but im stuck on the header. to me it seems a bit short, could it be malformed? i would appreciate any help. the pdu type is 6, although i dont really know what that means to be honest. can someone give me a link to a paper where these types are descibed?

thanks in advance

Hi Michael,

This looks like a WAP Push PDU (WSP).

73 - transaction id
06 - push PDU
04 - headers len
AE - content-type: application/vnd.wap.sic
8D 01 FB - Content-length: 251

application/vnd.wap.sic content follows


The service centre number and sender number are not part of this PDU. They would be part of an SMS PDU that would carry this message.

If a WAP Push is sent in an SMS message, then you have a WSP WAP Push PDU that is packaged inside a WDP PDU for SMS. The WDP PDU then gets packaged inside of an SMS PDU.

The WSP and WDP specifications are part of the WAP Protocols, which can be found at http://www.openmobilealliance.org/Technical/wapindex.aspx

SMS PDU formats vary based upon what protocol you are using to interface with SMS. For example, if your interface is SMPP, you would refer to the SMPP protocol (and the service centre number is not available via SMPP). If you are using a GSM modem, then ETSI GSM 07.05 and 03.40 would apply (http://www.etsi.org).

Hi,

The MIME content type is application/vnd.omaloc-supl-init.

It appears to be a type defined by the Open Mobile Alliance (http://www.openmobilealliance.org). I assume it is somehow related to SUPL location services.

I did find some other info here:

http://support.nowsms.com/discus/messages/132/21808.html

However, for more detail, I'd suggest checking the SUPL and location related enabler specification at the OMA web site.

0B000302020105040B841C6B is the SMS User Data Header.

I'd assume the 8C before that is message length.

This looks like a WAP Push PDU (WSP) containing a Service Indication (SI).

01 - transaction id
06 - push PDU
06 - headers len
AE - content-type: application/vnd.wap.sic
B4 82 - push-flag: 2
8D 01 C7 - content-length: 199
SI content follows

Service Indication format has its own spec (WAP 167) in the library at http://www.openmobilealliance.org/Technical/wapindex.aspx. WSP header encoding is WAP 203.

Thanks a lot for your support Bryce.
In the above PDU, last byte "00" is acceptable as per WAP specification?


The complete PDU:

000310BDF0018E0460001847D6000C2820C0008008FC02E1004181ABAD20A34071C0415A80117183 00DDD85C1C1D5CDA0B8C4E0E4B98DB8BCFD95B4F535519CD535518CC9355124D539A938E135119DE 935B539B139E939B165A929B169A99CCD355D34D1695D29B1355D49A5391D64D1351D24D13D1118E 1355105DD31A915D588CD6941395CD1D53D11A1C931A915E93D5104C0003061401231418480A0140 0E06040D32C8C480

Without spending a lot of time decoding this, I would say the last byte "00" is invalid. But a good decoder would simply stop when it reaches the closing of the last open WBXML tag. "01" is a tag closer.

For the other PDUs ... you'd need to give me some clue as to the context in which you are seeing them.
