The Research and Design of IMS Network Management

Abstract

Network management is important means to ensure the normal operation of the network. As an important component, it and other network technologies keep pace. IMS is a core network of service control initiated by NGN. With the separation of control and bearer and the separation of control and service, IMS can support many kinds of access modes, and can achieve the integration of fixed network and mobile network. At present, most of the research for the IMS is forced on the functional entities, interfaces, service quality and so on. As the result, the research on the IMS network technology will do good to the IMS development and reliable operation. Firstly, an introduction of the IMS network is given in this thesis, and the functional entities of the IMS and network management technology, such as TMN network management technology and SNMP network management technology are analyzed in detail. Then based on Net-SNMP and SNMP4J Open Source technology, the program of IMS network management is implemented on the J2EE platform. In the end, IMS network management system is tested on the Open IMS Core experiment platform, which also verified the feasibility of the system.
