To detect whether a 'deliver_sm' is a delivery report or a message, you have to check the 'esm_class' field. If bit 2 of this byte is set ( 0x04 ), it is a delivery report. To use delivery reports, you have to setup a transceiver connection to the SMPP provider, because you are going to send and receive messages.
The SMPP (Short Message Peer-to-Peer) protocol is an open, industry standard protocol designed to provide a flexible data communications interface for the transfer of short message data between External Short Message Entities (ESME), Routing Entities (RE) and Message Centres (MC).

SMSC#1 forwards the message via a deliver_sm to ESME#2. ESME#2 sends back a deliver_sm_resp, with a message_id=2000 (which is generated by ESME#2). Note: Though SMPP 3.4 spec does not mention this, many implementations put a message_id to support delivery receipt. SMSC#1 receives the deliver_sm_resp.

2.1 SMPP Overview. Short Message Peer to Peer (SMPP) protocol is an open message-transfer protocol that enables short message entities (SMEs) outside the mobile network to interface with an SMSC. Nonmobile entities that submit messages to, or receive messages from an SMSC are known as External Short Message Entities (ESMEs).

SMPP supports delivery receipts / reports (DLRs) for SMS messages so that your application can determine delivery outcomes. The returning of a message delivery receipt / report (DLR) is dependent on the value set in the registered_delivery field of the message originally sent from the ESME to the MC in an submit_sm operation.
