SMPP (Short Message Peer-to-Peer) 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). The SMPP protocol is a means by which applications can send SMS messages to mobile devices and receive SMS from mobile devices.
Services from Melrose Labs support SMPP v5 and the earlier versions, v3.3 and v3.4. The v5 specification is the latest and final version of SMPP that was published, is the most capable version, and is the best version to read for an understanding of SMPP.
Session Management Operations
These operations are used to establish and maintain an SMPP session.
The purpose of the SMPP bind operation is to register an instance of an ESME with the MC system and request a SMPP session over this network connection for the submission or delivery of messages. Thus, the Bind operation may be viewed as a form of MC login request to authenticate the ESME entity wishing to establish a connection.
- bind_transmitter / bind_transmitter_resp
- bind_receiver / bind_receiver_resp
- bind_transceiver / bind_transceiver_resp
- unbind / unbind_resp
Message Submission Operations
Message submission operations provide an ESME with the ability to submit messages for onward delivery to mobile stations.
Message Delivery Operations
Message delivery operations provide the means of delivering short messages from a MC to an ESME. These messages typically originate from mobile stations.
Message Broadcast Operations
Message broadcast operations provide Cell Broadcast services to ESMEs.
- broadcast_sm / broadcast_sm_resp
- Broadcast TLVs
Anciliary Submission Operations
Ancillary submission operations provide additional management of messages submitted by ESMEs. This includes cancellation, querying and replacement of messages.
- cancel_sm / cancel_sm_resp
- query_sm / query_sm_resp
- replace_sm / replace_sm_resp
- Message Replacement TLVs
Anciliary Broadcast Operations
Ancillary broadcast operations provide additional management of messages submitted by ESMEs. This includes cancellation and querying of messages.
- query_broadcast_sm / query_broadcast_sm_resp
- Query Broadcast TLVs
- cancel_broadcast_sm / cancel_broadcast_sm_resp
- Cancel Broadcast TLVs
