In this paper the authors propose 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.
