A Real-Time Observation scheme for UMTS networks

In this paper, we propose a real-time observation scheme for UMTS networks. There is a 3GPP specification for subscriber and equipment trace, but it only provides the basic aspects of subscriber and equipment trace. Thus, it is very hard to define and develop various parameters for effective trace. Now we define three types of real-time observation scheme - event trace, periodic trace, and call observation. We called these types of call tracing method real-time observation, and propose the data format for three schemes. Using these schemes, we can be able to keep real-time observation on a specific mobile more effectively.
