Full-Service Operation and IMS Network Management

Nowadays ,many carriers choose IP Multimedia Sybsystems as an approach to all-service operation. Traditional network management concepts are not applicable to IMS network management. This is because the IMS network is characterized by a flat,all-IP architecture ,simplified functionality of Network Elements ,and a variety of NEs. This paper will proceed to introduce IMS network management system construction that underlies all-service operation. It will then discuss unified IMS network management at the Element Management Layer,the increasing importanceof end-to-end application,and the acceleration of eTOM and ITIL integration
