SMPP delivery report

Question

How to check for the delivery report of the sent message. I am using PHP and I have the SMPP account. Can somebody help me with the checking of delivery report?

Will I get a delivery report as message like we get in our mobile?
Or the status of the send function will do for it?

Answer 1

Using SMPP you can retrieve delivery report in the following ways.

First choice is to set registered_delivery parameter to 1 when you send submit_sm PDU.
In this case SMSC should send you deliver_sm PDU with esm_class = 0x04 containing delivery report.

Other way is to request delivery status with query_sm command but this may generate more traffic if polling SMSC too often.

Answer 2

If you're asking about the format in which the Delivery_Receipt will be delivered back to the source then it's carried as the user data payload in the SMPP deliver_sm or data_sm operation.

The following fields are relevant in the deliver_sm and data_sm operations when used for transmitting delivery receipts:

• source address (i.e. source_addr_ton, source_addr_npi, source_addr)
• destination address (i.e. dest_addr_ton, dest_addr_npi, destination_addr)
• esm_class
• message_state
• network_error_code
• receipted_message_id
