Universal Mobile Telecommunication System (UMTS) is a third generation system for efficient data packet radio transmission services. The three mobility management (MM) states PMM detached, PMM connected, and PMM idle are defined for efficient management of radio resources and signaling networks. In addition, two radio resource control (RRC) states idle and connected are introduced for the management of more detailed location information. The connected state is further divided into cell connected and URA connected states. These MM state models and RRC state models are combined together. The user equipment (UE) state transition behavior is modeled and the steady state probability of the UE states is derived using a semi-Markov process approach. The effect of various input parameters on the steady state probability is investigated.
