IMS architecture

IMS (IP Multimedia Subsystem) is a framework that allows different types of communication services—like voice calls, video calls, and messaging—to work seamlessly over the internet. It separates the service logic from the underlying network hardware, enabling providers to deliver a wide range of multimedia services consistently across devices. Think of it as an organized system that manages how different communication methods are delivered and interconnected, ensuring high-quality, reliable, and flexible multimedia experiences for users regardless of device or location.
