| Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 99 === In cellular networks, when the Base Station (BS) has no the extra available
channels, the handover procedure of communicating Mobile Station (MS) will be
failed. As a result, it caused to call blocking which will decrease the customer
satisfaction and result in financial loss. Therefore, the channel allocation for call block
avoidance is an important issue of resource management in cellular networks. In this
paper, we propose a mechanism which considers the real-time traffic information (e.g.,
traffic flow and vehicle speed) and the user behaviors (e.g., call inter-arrival time and
call holding time) to analyze the adaptable amount of communication calls in the
specific cell for channel allocation. In conducting the experiments of Call Block
Probabilities (CBP), we simulate two cases by the situations of the whole day and
traffic accident. The simulation results show that the CBP proposed by our scheme in
the case of the whole day can decrease 3.37% CBP, compared to that of SCA scheme.
Moreover, the CBP proposed by our scheme in the case of traffic accident can
decrease 30.23% CBP, compared to that of SCA scheme. Therefore, our proposed
mechanism is more effective that can decrease the number of CBP.
