SMS are created on mobile phones or personal computers. These devices send SMS with the help of a GSM network (Global System for Mobile communication). All the devices have External Short Messaging Entities (ESMEs).
ESMEs are the starting point and end-point of SMS. However, they cannot communicate directly. The starting point - the source sends SMS to Short Message Service Center (SMSC). The SMSC Gateway is the entity in charge of storing and forwarding messages to and from mobile stations. The ESME can be a fixed network or a mobile station that receives and transmits messages.
Further, for completing this process of sending and receiving SMS, you need a protocol, such as SMPP, SS7, SIGTRAN, SDP, and HTTP protocols. Here, we will discuss the SMPP Protocol.
