Glossary definition of SMSC

Also known as: Short Message Service Centre

Short Message Service Centre (SMSC) is an element within a mobile telephone network that handles all SMS text messages.

The SMSC receives the incoming SMS text from the user who has sent it, and then either passes it onto the recipient telephone, or stores the message for a predetermined time. When the terminal of the recipient is switched on, and is within range of a Base Station, then the SMSC will forward the message to the destination and the operation is complete.
