What is SMSC?
SMSC is a software application that resides in the mobile network operator's infrastructure. It receives SMS messages from the sender's device and stores them until they are delivered to the receiver's device. SMSC also ensures that the message is delivered to the correct recipient and provides delivery reports to the sender. There are two types of SMSC: home SMSC and visitor SMSC. Home SMSC is responsible for delivering messages to its subscribers, while visitor SMSC delivers messages to subscribers of other networks.
When a user sends an SMS, the message is first sent to the SMSC. The SMSC checks if the message is valid and then routes it to the appropriate destination. If the recipient is on the same network, the message is delivered to the home SMSC. If the recipient is on a different network, the message is forwarded to the visitor SMSC. The SMSC then sends a delivery report to the sender, indicating whether the message was successfully delivered or not.
There are two types of SMSC: basic SMSC and enhanced SMSC. Basic SMSC is a simple messaging system that only provides basic message queuing and delivery functions. Enhanced SMSC, on the other hand, provides additional features such as message filtering, message storage, and message delivery confirmation.
SMSC vs SMS Gateway
SMSC and SMS gateway are often used interchangeably, but they are not the same thing. While SMSC is responsible for message routing and delivery, SMS gateway is a hardware or software application that connects mobile devices to other communication networks such as email, social media, or instant messaging.
