IP Multi-media Subsystem (IMS)

IP Multimedia Subsystem (IMS) is a framework that enables carriers to deliver a variety of multimedia services—like voice calls, video sharing, and messaging—over the internet. It uses internet protocols to integrate different communication methods into a unified system, allowing seamless and flexible service delivery across devices and networks. IMS standardizes how these services are managed, ensuring reliability, security, and quality. Essentially, it acts as a backbone that connects traditional telephony with modern internet-based communication, providing a consistent experience for users regardless of their device or network type.
