| Summary: | 碩士 === 國立交通大學 === 資訊工程研究所 === 81 === This thesis proposes a cellular mobile traffic simulation sys-
tem which can reflect the real coverage and signal environment.
In the Cellular Mobile System, The CELL coverage areas are
normally irregular and overlapped. The call processing
features, i.e. Direct-Retry and Hand-Off, involve many
cells. Under this circumstance, It is difficult to analyze or
estimate the Quality- of-Service (QOS) through traditional
analytical calculations. Computer simulation offers a feasible
way to estimate these QOS parameters. We have built a Model
which adopted the geographical information in coverage and
signal representation, followed by the real system call
processing scenarios which can make the results more
realistic. Via simulation, the maintenance, design and
traffic management personnel are able to make right decisions .
Since call processing procedures are discrete-events, we use
ｓｍｐｌ as a tool to implement simulation model.
