This thesis describes protocols used in IP Multimedia Subsystem (IMS) networks. Freely available implementations of IMS system are described. The main goal is to describe design and implementation of a tool for analyzing communication between users and IMS system. The tool seeks and decodes signaling messages. These messages are analyzed for information about sessions which are necessary for session monitoring and accounting. Final gathered information are exported in a form of extended NetFlow/IPFIX records. We used open-source Open IMS Core implementation for building IMS network and creating test data. As endpoints we used another open-source application for Android OS called IMSDroid.
