Major IMS Network Components and Their Functions

IMS Core: The IMS Core is the central component of an IMS network. It is responsible for call control, session management, and authentication and authorization of users.

1. IMS Application Servers: These servers host various applications that provide services such as Voice over IP (VoIP), video conferencing, instant messaging, and multimedia services.
2. IMS Gateways: IMS Gateways are used to connect the IMS network with external networks, such as the traditional telephone network (PSTN) or the internet. They provide protocol conversion and media transcoding.

The IMS Core handles the signaling and routing of calls and sessions, while the IMS Application Servers provide the actual services. IMS Gateways enable communication between the IMS network and other networks.
