Message Submission TLVs
SMPP Message Submission TLVs
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.
Message Submission Request TLVs
This section lists TLVs that may be used for message submission operations.
| TLV Name | Description | Ref. |
| alert_on_msg_delivery | Request an MS alert signal be invoked on message delivery. | 4.8.4.2 |
| billing_identification | Billing information passed from ESME to MC. | 4.8.4.3 |
| callback_num | A call-back number associated with the short message. This parameter can be included a number of times for multiple call-back addresses. | 4.8.4.15 |
| callback_num_atag | Associates a displayable alphanumeric tag with the call-back number. If this parameter is present and there are multiple instances of the callback_num parameter then this parameter must occur an equal number of instances and the order of occurrence determines the particular callback_num_atag which corresponds to a particular callback_num. | 4.8.4.16 |
| callback_num_pres_ind | Defines the call-back number presentation and screening. If this parameter is present and there are multiple instances of the callback_num parameter then this parameter must occur an equal number of instances and the order of occurrence determines the particular callback_num_pres_ind which corresponds to a particular callback_num. | 4.8.4.17 |
| dest_addr_np_country | E.164 information to the operator country code. | 4.8.4.20 |

| dest_bearer_type | The correct bearer type for delivering the user data to the destination. | 4.8.4.24 |
| dest_network_id | Identification of destination network. | 4.8.4.25 |
| dest_network_type | The correct network for the destination device. | 4.8.4.26 |

| dest_subaddress | The sub-address of the message destination. | 4.8.4.28 |
| dest_telematics_id | The telematics identifier associated with the destination. | 4.8.4.29 |
| dest_port | Indicates the application port number associated with the destination address of the message. This parameter should be present for WAP applications. | 4.8.4.30 |
| display_time | Provides the receiving MS with a display time associated with the message. | 4.8.4.31 |
| its_reply_type | The MS user’s reply method to an SMS delivery message received from the network, is indicated and controlled by this parameter. | 4.8.4.33 |
| its_session_info | Session control information for Interactive Teleservice. | 4.8.4.34 |
| language_indicator | Indicates the language of an alphanumeric text message. | 4.8.4.35 |
| message_payload | Contains the extended short message user data. Up to 64K octets can be transmitted. Note: The short message data should be inserted in either the short_message or message_payload fields. Both fields should not be used simultaneously. The sm_length field should be set to zero if using the message_payload parameter. Note: In the case of data_sm, the message_payload TLV is the only means of specifying text. | 4.8.4.36 |
| more_messages_to_send | Indicates that there are more messages to follow for the destination SME. | 4.8.4.38 |
| ms_msg_wait_facilities | This parameter controls the indication and specifies the message type (of the message associated with the MWI) at the mobile station. | 4.8.4.40 |
| ms_validity | Indicates validity information for this message to the recipient MS. | 4.8.4.41 |
| number_of_messages | Indicates the number of messages stored in a mail box. | 4.8.4.43 |
| payload_type | Defines the type of payload (e.g. WDP, WCMP, etc.). | 4.8.4.44 |
| privacy_indicator | Indicates the level of privacy associated with the message. | 4.8.4.45 |
| qos_time_to_live | Time to live as a relative time in seconds from submission. | 4.8.4.48 |
