| Abstract | Cellular networks have to guarantee a high quality of service for a large number of mobile users within given geographical distribution. Therefore, appropriate sets of performance parameters have to be defined and then fulfilled under reference load conditions. This research work studies about cellular network traffic characteristic, measures the traffic of an operating CDMA cellular network of "Skytel" Co.Ltd in Mongolia, and analysis its radio network performance and user behavior. The network has been implemented by STAREX-800 digital CDMA system of LGIC in Korea and IS95B standard. Base station Management System (BMS) of STAREX-800 is used to collect call statistics of radio network part during one-week period. The main performance measures, new call blocking, handoff call blocking and call drop rate of network are examined and they are compared with recommended GOS target values and performance of other operating networks. The result of measurement shows that bothway new call blocking is 2%, handoff blocking 0.046% and call drop rate is 0.9%. Blocking probability does not satisfy GOS target, but difference is not significant. Hence, traffic offered to cells is approximately equal to carried traffic. Terminating mean call holding time is around 70 seconds and originating mean call holding time is around 28 seconds. Terminating call-holding time 41 % higher, due to call charging difference between fixed and mobile network. Overall call holding time mean is 57 seconds and standard deviation is 132 seconds, which shows that call duration distribution has much more variation than according to exponential assumption. Channel and handoff holding times depend on user mobility. Daily traffic profile is different in each base station depending on cell type. |
