Impact of the Network Response Time on Hand-off in a Personal Communications Network

In a personal communications services (PCS) network, the network delay for a hand-off request is limited by a timeout period. If the network fails to respond within the timeout period, the hand-off call is forced terminated. We study the effect of the network response time on the performance (the call incompletion probability) of a PCS network. Our study indicates that at a small offered load, the network response time has a significant effect on the call incompletion probability. At a large offered load, the poor performance due to slow network response time can be compensated by increasing the number of radio channels. We also observe that the effect of the network response time is more significant if the portable residual time distribution at a port coverage area has a smaller variance. Thus, the design of the network hand-off time objective should consider the movement behavior of the PCS users. 1 Contact author: Professor Yi-Bing Lin, Dept. Comp. Sci. & Info. Engr., Natl. Chiao ..
