This paper proposes an efficient resource management method for the IMS (IP Multimedia Subsystem) related mobile network services. Mobile wireless services associated with the IMS include multimedia telephony (MT), instant messaging (IM) and full browsing. To access those services the subscriber should register on the related system of the mobile wireless network. Even when the usage frequency is low for many cases, resources such as the session and the database are occupied by them. Those usage patterns could incur the overinvestment in the system build-up. Also it gets more important to manage the IMS related resource management especially in the next generation mobile network services. In this paper a cost effective IMS management method is proposed which is necessary for planning the network evolution. To reach an ultimate goal of the All-IP network, it is inevitable to have a transient period including both the circuit and the packet based data network. At the stage of those hybrid networks, it is required to establish them in an efficient manner in terms of resource usage which is deeply related with the TCO (Total Cost Ownership). The multimedia telephony is one of the essential services in the advanced packet based mobile networks. In this paper a cost effective resource management method is proposed for deploying the multimedia telephony service while the legacy network co-exists. Simulation results show that main system elements required for the multimedia telephony and the instant messaging services can be scaled down while maintaining compatible quality of service level.
