Everyone in the industry adopting marketing campaign is very well aware of Bulk SMS Service which is used to connect to a large number of people together with a single click. This is not done through mobile phones. A connection between computer and telecommunication networks is very important to send these messages as these messages are sent through web networks over mobile phone networks. The connection to these networks is provided by some gateway providers. This connection is done with the help of the SMPP protocol. The abbreviation for SMPP is Short Message Peer to Peer. It is an industry standard protocol which is open and designed to maintain an interface for flexible data communications. This data communication is done between External Short Message Entities (ESME), Short Message Service Centers (SMSC), and Routing Entities (RE). There is no need for another internet connection. A standard internet connection is enough to do this. SMPP Server uses a level-7 TCP/IP protocol which allows direct access to network providers. This is also a reason why SMPP is known as “true SMS” protocol at times. Many gateway providers are offering 3.4 version of this protocol which is the most commonly used protocol but the latest version to this protocol is 5.0.

How SMPP is used as API?

To use the SMPP protocol for message communication, it is very important to establish an SMPP session. This session is established between ESME and Message Centre or SMPP Routing Entity depending on the need. An SMPP client is used to create this session for communicating with an SMPP protocol. The libraries based on the TCP/IP protocol and port programming (socket connection) is developed by developers. This helps the lower developers to create an SMPP client without excavating the information of port programming and TCP/IP protocol. To make sure whether the bind/connection is established properly or not, a continuous exchange of SMPP Protocol Data Units or Packets (PDU) is created. The work of SMPP client is to protect the SMS and ensuring the delivery of SMS to the destined server. The SMPP Server API is also used to transfer a delivery report to the client in return at times when there is a need. The need for a delivery report occurs in some cases such as any status change in the SMS.

Improving proficiency of bulk SMS with the help of the SMPP server:

Manage SMPP connectivity user: It enables the marketers to add SMPP users, remove them, assess the number of sessions bonded and detach SMPP connectivities.

Check Bind status: It enables the marketers to screen the total sessions, the status of sessions whether they are dead or alive, bind status of any SMPP users

Track SMS: This enables the marketers to track the campaign number, number of messages sent, delivery reports and status of the messages sent and delivered via request ID, sender ID, or Mobile number.

SMPP SMS consumption: It enables the marketers to know and keep an eye on the total amount of sessions running, number of DLR received, total consumption of messages, etc.
