MSC (Mobile Switching Center) is a key part of mobile phone networks that works like a super-smart traffic controller for phone calls and text messages. It's the central system that makes sure when someone makes a call or sends a message, it reaches the right person. Think of it as the brain of a mobile network that decides how to route communications and keeps track of where mobile phones are located. When you see this term in resumes, it usually means the person has experience working with core mobile network equipment and systems.
