Hello!

I try to send binary messages to Nokia phones using UCP protocol. The SMSC respond with an acknowledge but the message is not received by phone (tested on Nokia N80 and 6260).
But on other phones is received into the inbox (Siemens A50 and Samsung SGH-X100).
If i take the SIM from the Nokia phone and put it in my Siemens A50, all messages are received, mesages sended hours ago.

I put a sniffer to watch the communication between now.sms and SMSC and that are the strings:

now.sms:

Hi,

That is a bit of a mystery. I don't have any ideas for a solution. But I do have some ideas for things to try that might give us more information.

1.) Is it possible for you to connect one of those Nokia phones up to NowSMS as a GSM modem?

I'm curious whether you experience the same problem sending these messages through a GSM modem as you do going through your SMSC connection.

2.) There is an experimental update for NowSMS 2006 to add support for UCP/EMI delivery receipts. I'd be curious if you get back a delivery receipt when sending to the Nokia phones, even though the message does not appear.

Here's the thread about this experimental update:

http://support.nowsms.com/discus/messages/1/15696.html

3.) It looks like you are sending Nokia Smart Messaging ringtones. What if you try sending a simple WAP Push message to the same phones (just include a URL and some short text in the push ... leave other values at their defaults).

I have tried with Notification Request field using smsj framework (http://smsj.sourceforge.net/)
The smsc it says that the message was delivered to the mobile phone, even that the message is not displayed on the phone.
I believe that is something wrong with the XSer field (XSER_TYPE_UDH) or UDH field.
Do you know where i can find some documentation about UDH? and why the UDH is different when i send with UCP compared to an modem AT command (some extra bytes...).

I have Short Message Service Centre 4.6 EMI - UCP Interface Specification from LogicaCMG and is not explicit on format of the xser field and udh.

You have some other ideea where to focus my attention if not on UDH field?

Hi Mihai,

The UDH should be the same whether UCP or modem...

I have one idea...try editing SMSGW.INI...create a [UCP] header in the file (different from UCP - host:port] section) and add IncludeXSerDCS=no...the smsc might not be understanding this attribute and appending it to the UDH.
