SMPP data_sm
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.
4.2.2 data_sm Operation
The data_sm operation is similar to the submit_sm in that it provides a means to submit a mobile-terminated message. However, data_sm is intended for packet-based applications such as WAP in that it features a reduced PDU body containing fields relevant to WAP or packet-based applications.
4.2.2.1 data_sm Syntax
| Field Name | Size octets | Type | Description | Ref. |
|---|---|---|---|---|
| command_length | 4 | Integer | Set to overall length of PDU. | 4.7.4 |
| command_id | 4 | Integer | 0x00000103 | 4.7.5 |
| command_status | 4 | Integer | 0x00000000 | 4.7.6 |
| sequence_number | 4 | Integer | Set to a Unique sequence number. The associated data_sm_resp PDU will echo this sequence number. | 4.7.24 |
| service_type | Var. max 6 | C-Octet String | The service_type parameter can be used to indicate the SMS Application service associated with the message. Specifying the service_type allows the ESME to avail of enhanced messaging services such as “replace by service_type” or control the teleservice used on the air interface. Set to NULL for default MC settings | 4.7.25 |
| source_addr_ton | 1 | Integer | Type of Number for source address. If not known, set to NULL (Unknown). | 4.7.1 |
| source_addr_npi | 1 | Integer | Numbering Plan Indicator for source address. If not known, set to NULL (Unknown). | 4.7.2 |
| source_addr | Var. max 65 | C-Octet String | Address of SME which originated this message. If not known, set to NULL (Unknown). | 4.7.29 |
| dest_addr_ton | 1 | Integer | Type of Number for destination. | 4.7.1 |
| dest_addr_npi | 1 | Integer | Numbering Plan Indicator for destination. | 4.7.2 |
| destination_addr | Var. max 65 | C-Octet String | Destination address of this short message For mobile terminated messages, this is the directory number of the recipient MS. | 4.7.8 |
| esm_class | 1 | Integer | Indicates Message Mode and Message Type | 4.7.12 |
| registered_delivery | 1 | Integer | Indicator to signify if a MC delivery receipt or an SME acknowledgement is required. | 4.7.21 |
| data_coding | 1 | Integer | Defines the encoding scheme of the short message user data. | 4.7.7 |
| Message Submission TLVs or Message Delivery TLVs | Var. | TLV | 4.2.4 |
4.2.2.2 data_sm_resp Syntax
| Field Name | Size octets | Type | Description | Ref. |
|---|---|---|---|---|
| command_length | 4 | Integer | Set to overall length of PDU. | 4.7.4 |
| command_id | 4 | Integer | 0x80000103 | 4.7.5 |
| command_status | 4 | Integer | Indicates outcome of data_sm request. | 4.7.6 |
| sequence_number | 4 | Integer | Set to sequence number of original data_sm PDU. | 4.7.24 |
| message_id | Var. max 65 | C-Octet String | This field contains the MC message ID of the submitted message. It may be used at a later stage to query the status of a message, cancel or replace the message. | 4.7.14 |
| Message Submission Response TLVs or Message Delivery Response TLVs | Var. | TLV | 4.2.5 |
SMPP Tools and Services
Services from Melrose Labs (e.g. Tyr SMS Gateway and SMPP SMS Gateway ) support SMPP v5 and the earlier versions, v3.3 and v3.4.
SMPP Load Test
Perform an SMS load test using SMPP from your web browser and view the results in realtime. SMPP Load Test tool submits SMS messages using SMPP at the specified rate. Messages are sent to one or more mobile numbers in a range from a single source address or range of source addresses.

SMPP Analyser
The SMPP Analyser acts as an SMPP proxy, with the client application binding to the service and the service onward binding to the SMSC or SMS Gateway. Packet captures can be viewed in your browser or exported into Wireshark.
