摘要

本文将固定信道分配(Fixed Channel Assignment)和动态信道分配(Dynamic Channel Assignment)相结合

提出了一种高效信道借用算法HEBCA(High Efficiency Channel Borrowing Algorithm).它利用预期信道可用率(Expected Future Channel Availability Rate)衡量信道借用对周围小区的影响

针对信道借用发生和信道借用结束设计了两种重排操作.计算机仿真表明

本算法的阻塞概率低于BDCL(Borrowing with Directional Channel Locking)

对改善FCA在业务量低端的性能很有帮助.本算法的信道重排比率(Channel Reallocation Ratio)也明显低于BDCL.

Abstract

Based on the study of Fixed Channel Assignment and Dynamic Channel Assignment

we bring up a new High Efficiency Channel Borrowing Algorithm.It employs the concept of Expected Future Channel Availability Rate to evaluate the effect of channel borrowing on adjacent cells.It includes two channel reallocation procedures to avoid collision.Computer simulation shows that this algorithm has lower Blocking Probability than BDCL(Borrowing with Directional Channel Locking).The Channel Reallocation Ratio is also lower than that of BDCL.
