Generate header for concatenated messages?

Post by AG70 » Tue Aug 17, 2021 9:17 am

Hi,

My SMSC is devided into two parts. SMSC_Server to receive SMS messages from SMSC Client and SMSC Transmitter to send the SMS messages to the operator.
For example SMSC_Server receives and parse long message with UDH's 050003020401, 050003020402, 050003020403, 050003020404

Now my SMSC_Transmiiter collect the text and UDH for each part and need to send it to SMSC operator.
Question is how to add the UDH generated by the SMSC_Server to each part of the message in Header or along with the Text message.

I need concatenated messages for ASCII or Default and for UCS2.

Here is my code:

Code: Select all

 Inetlab.SMPP.Builders.ISubmitSmBuilder builder = SMS.ForSubmit()
	.Data(ByteArrayHelper.FromHex(ByteArrayHelper.ConvertStringToHEX(msg.t42_msg_text)))
	.From(msg.t42_originator, (AddressTON)msg.t42_originator_ton, (AddressNPI)msg.t42_originator_npi)
	.To(msg.t42_destination, (AddressTON)msg.t42_destination_ton, (AddressNPI)msg.t42_destination_npi)
	.Coding(Enum.Parse<DataCodings>(msg.t42_encoding))
	.DeliveryReceipt()
	.Set(esmclass => esmclass.EsmClass = 0x40)
	.ExpireIn(TimeSpan.FromDays(3))
	.Set(sm => sm.Header.Sequence = (uint)msg.t42_seq_number);

	
	IList<SubmitSmResp> resp = await _client.SubmitAsync(builder);

Code: Select all

public static string ConvertStringToHEX(string str)
        {
            string results = string.Empty;

            uint iChar;
            char[] cArray = str.ToCharArray();

            foreach (char c in cArray)
            {
                iChar = c;
                results += iChar.ToString("X4");
            }

            return results;
        }
Thanks for any help,
AG
