Analysis on Call Blocking Probability of Streaming Data Service in CDMA System Interworking with WLAN for Different Cell Geometry

摘要

Call blocking probability of streaming data service in CDMA system interworking with access point(AP) of WLAN is analyzed for different cell geometry of base station(BS) and AP. Queuing is modeled. The considered system leads to successful handoff between APs of WLAN. Blocking probability is calculated as a function for the ratio of BS and AP size, their location and the number of buffers. Results show that blocking probability is not influenced by BS and AP location but mainly by the ratio of their size. For CDMA system of radius 100m, 5 buffers and 7dB noise rise(NR), in order to obtain 1% call blocking probability, CDMA system interworking with WLAN of radius 20m has more 0.4Erlang than that of radius 60m.
