RE: Concatenation Problem in SMPP

[Oded Arbel]

the ESM setting is correct to enable UDHI (user data header indicator). AFAIK, the SMPP  driver does not send MMS (this logic is actually out of scope for the driver as the smsbox is doing the splitting) but instead relies on the fact that splitted messages contain the correct UDH for concatenation as in the SMS standard [3GPP TS 23.040], which it does as you've noticed - the "additional field" you quote is indeed the UDH concatenation header.   According to the SMS standard, the SMSC should not have any knowledge of concatenated messages, as splitting is done on the sending entity and composing is done on the receiving entity- the delivering entity should only route the message parts, not even necessary in the same order as they were sent.   -- Oded Arbel m-Wise mobile solutions [EMAIL PROTECTED]   +972-9-9581711 (116) +972-67-340014   ::.. capsule on reentry flickering match doused -----Original Message----- From: Dedy Sutanto [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 17, 2002 5:15 AM To: [EMAIL PROTECTED] Subject: Concatenation Problem in SMPP Dear all,   I have done test for concatenation messages via SMPP. Here the scenario:   Turn on debug in smsc_smpp.c Put Parameter in cfg file group sendsms-user: concatenation = true   Send SM via http interface with text more than 160 characters.   Result -          I found when kannel send concatenation messages, the ESM change to 67 - 0x00000043 (it should be 0). The result I received the SM with characters I cannot read. -          From SMPP 3.4 Specification, the tag for more message to send (MMS) is optional parameter which must be put after the SM. But what I found here, the SM which send by kannel have additional field in beginning of message those are 05 00 03 07 02 01. The result, SMSC is not treating those messages as concatenation messages. I just wonder, do SMPP-MMS implementation in kannel followed the standard specification?   I hope this information useful   Regards -dedy-           Result from debug kannel.   2002-09-17 08:55:25 [5]
