IMS
IMS (IP Multimedia Subsystem) is a framework used by telephone companies and mobile operators to deliver modern communication services. Think of it as the behind-the-scenes technology that helps deliver voice calls, video calls, messaging, and internet services all through the same network. It's like a universal translator that helps different types of communication services work together smoothly. When you make a call or send a message that works on both Wi-Fi and cellular networks, IMS is often the system making that possible.
