- Abstract
- In this paper, we propose the bandwidth borrowing scheme to improve the performance of the blocking probability and analyze the performance of call admission control schemes with bandwidth borrowing and bandwidth reservation. In general, the target transmission rates of communications and streaming services are fixed, but data services do not have the target transmission rates. Therefore, we can control the transmission rates for data services flexibly according to the system loading situation. The bandwidth borrowing scheme is implemented by the transmission rates control of data services through packet scheduler. We make the queueing model about our system model. However, it is difficult to get the analytic solution, so we demonstrate the results through simulations. The simulation results show that there is a 8.7 -35.2 dB gain at the total blocking probability according to the use of bandwidth borrowing scheme and the use of the bandwidth reservation scheme and the bandwidth borrowing scheme causes to decrease the handoff blocking probability.
