Impacts of Inactivity Timer Values on UMTS System Capacity
01 March 2002
UTRAN is a 3G radio access network based on the wide-band DS_CDMA technology. An important feature of UTRAN is its multimedia service capability. UMTS supports high bit rate and variable bit-rate services, packet data and internet access. When a user sets up a data session, a downlink code is allocated. In UMTS, unless secondary scrambling code is used, there is a shortage of downlink codes. In this paper, we study the impacts of inactivity timer values on UMTS system capacity.
