【Abstract】 A novel channel borrowing scheme based on priority (CBP) is presented in this paper. In this scheme, each nominal channel of a cell has its priority for borrowing. When a channel is borrowed, its CIR (Carrier to Interference Ratio) is measured. By this strategy, numerous borrowing locking and signaling exchanging are needless. This characteristic is necessary for application in GSM systems. The simulation shows that this scheme can reduce blocking rate and improve capacity in hotspot traffic model evidently.更多还原
