Abstract
In this paper we identify the needs and critical issues of management and monitoring in IP Multimedia Subsystem (IMS). As an IMS provides a layered architecture converging heterogeneous networks; it requires network management as well as service management. We provide a framework for managing an IMS system by utilizing network management server, session management and service managed objects (SMOs). SMOs are similar to managed objects (MO) except they are used for managing the provided services, error detection and fault recovery in services.
