What is the SMPP Protocol?

Nowadays, with the growing use of smartphones in different parts of life, many organizations and operators are using SMS services in their various business sectors, so we introduced SMPP protocols which allow you to communicate in simple language. It provides communication between the Internet and Telecom and your messages can be received over the Internet on a smartphone. The Peer-to-Peer SMPP Protocol is an open protocol, industry standard protocol designed to provide a flexible data communication interface for the transfer of short message data between external SMS (ESME) and routing (RE) and message center (RE). MC) designed. It is a protocol through which applications can send SMS messages to mobile devices and receive SMS messages from mobile devices. This is done by connecting an SMPP to a Short Message Service Center (SMSC), a short message gateway, a SMPP gateway, or a hub. It can also be used as an API for use with the USSD, CBC and other mobile services.

Supports cellular technologies

SMPP is designed to support text messaging capabilities for any cellular technology and has specific applications and features for technologies such as GSM, UMTS, LTE, IS-95 (CDMA), CDMA2000 (1xRTT and 3xRTT), ANSI-136 (TDMA), iDEN

Common SMPP Applications

The variety of messaging applications, especially texting, which SMPP can use, is almost limitless. Mobile operators, message center vendors, infrastructure providers, and app developers are constantly developing new applications for SMS. SMPP is an ideal protocol for accessing these applications. Some of the applications of SMPP are summarized below.

Marketing: Businesses send out promotional text messages to customers.

Booking Confirmations : Hotels, Restaurants, Taxis. Text messaging is better than instant messaging.

Appointment Reminders and Meetings : Used in businesses to remind clients about appointments and prevent financial impact or impact on a missed appointment.

Two-step authentication / OTP: Use SMS to send code that is used as a second agent to authenticate when logging in.

Voice Message Alerts VPS (Voice Processing System) Origin: Displays voice messages in the customer's mailbox. This is probably one of the first ESME-based text messaging applications and is still widely used in the industry.

Intelligence: For example, an application that enables mobile subscribers to query exchange rates or share price information from a database, etc., and display it as a text message on their phones.

Voice to text : Calls that are made directly to the phone or transmitted to an operator that sends the message to the MC to be transmitted to the subscriber's phone.

Directory Services: For example, a subscriber calls a directory service and requests information from restaurants in an area. The operator lists the available restaurants and sends the appropriate information as SMS to the caller.

Security applications : such as alert systems that can use SMS services for remote access and alert purposes. For example, parents receive a text message from their security company informing them that their daughter is home.

Online banking : stock trading and e-commerce. A mobile user can use SMS to send messages to ESME and request to buy products, stocks, and so on. Similarly, the subscriber may use SMS to access banking services such as bill payment and money transfer.

SMPP Functional Sections : In order to use the SMPP protocol, an SMPP meeting must be established between the ESME and the SMPP message center or routing unit if necessary. The session is based on an application layer TCP / IP connection between ESME and MC / RE and is usually initiated by ESME. This connection is often over the Internet and can use SMPP over TLS or VPN for connection security. SMPP is assigned to IANA on TCP 2775 port but other ports are often used.

There are three parts to the ESME function:

Transmitter (TX) - Once approved as a transmitter, an ESME can send short messages to the MC to send to mobile stations. A sender connection also allows the ESME to be canceled, queried or to replace previous messages. The messages sent are often referred to as terminated cell phone messages.

Receiver (RX) - Enables an ESME receiver session to receive messages from the MC. These messages typically originate from mobile stations and are referred to as mobile origin messages.

Transmitter and Receiver (TRX) - A TRX connection is a combination of TX and RX, so that an SMPP connection can be used to send terminated mobile messages and receive mobile origin messages. SMPP v3.3 does not support TRX connection. TRX connection support is available in SMPP v3.4 and v5. In addition, the message center can create an SMPP session by connecting to ESME. This is called the connection session.

How the protocol and PDU work

The SMPP protocol is a set of operations, each of which comprises a single protocol data request (PDU) request and response, which includes an SMPP command. For example, if the ESME wishes to send an SMS, it can send the PD_Sub_sm to the MC. The MC responds by sending sm_resp PDU, which indicates the success or failure of the request. Likewise, if the MC wants to send its message to ESME, it may send a delivered PDU to ESME, which in turn uses the delivery_sm_resp PDU as a means of verifying delivery. Special to ESME and others to MC. Others may be specific to a particular session type. Referring to the Sub_sm_ samples and the delivery of ___ Sm above, an ESME can only send _ sm to MC if a TX or TRX session is created with that message center. Likewise, an MC may only deliver delivered PDUs to ESMEs that have created RX or TRX sessions. Protocol performance is broadly divided into the following groups:

• Connection Management: This operation is designed to enable SMPP connections between ESME and MC and provides a means to handle unexpected errors.
  
• Message Delivery: This operation enables an MC to send messages to the ESME.
  
• Send Message: This operation is explicitly designed to send a message from ESME (s) to MC.
  
• Message broadcast: These operations are designed to provide cell broadcast services in the message center.
  
• Auxiliary Operations: These operations are designed to provide advanced features such as canceling, querying or replacing messages.
