摘要:A UMTS network based on the Wide Band-CDMA technology is a 3rd generation telecommunication system which provides various multimedia applications along with the conventional telephony service. These various multimedia applications fall into four different categories, which are differentiated from each other on the basis of required bit rate and delay tolerance etc. parameters. In order to get best Quality of Service (QoS) for a particular application running on the subscriber equipment the parameters of the respective category to which the application belong need to be in a required range. In this work the performance of a UMTS network scenario is evaluated by using various values of the precedence bits of the CBR application. The simulation tool used is QUALNET 5.0. The performance of the scenario according to the respective precedence bits is analyzed by four metrics: average jitter, end to end delay, throughput and UMTS signals received and forwarded to MAC. The comparative analysis of all the four metrics according to the precedence bit values will be carried out and it will be concluded in the last section that which precedence bit gives the best performance for the simulated UMTS network scenario.
