摘要
本文介绍了蜂窝移动通信系统中一种新的动态信道指配策略──基于紧凑模式的信道借用指配策略（ＣＰＣＢ）．这种策略不仅具有基于紧凑模式的动态信道指配的优点，而且具有固定信道指配策略中信道借用的优点．作者将新算法在一种普遍采用的４９个蜂窝的蜂窝通信网络上进行了仿真，分别对几种均匀和非均匀模式的业务分布情况进行了比较，结果表明：ＣＰＣＢ的系统平均阻塞率低于ＦＣＡ、ＢＤＣＬ、基于ＣＰ的ＤＣＡ和ＣＰＭＣＢ等，而且随着负载的增加，其系统平均阻塞率的增长速率也明显低于上述各种策略．
This paper proposes a new dynamic channel assignment strategy in cellular mobile communication systems, which is called compact Pattern based channel borrowing assignment strategy (CPCB). The new strategy combines the advantages of compact pattern dynamic channel assignment with fixed channel assignment with channel borrowing. CPCB is simulated in the conventional 49cell network. Compared with the average blocking probabilities of fixed channel assignment (FCA), borrowing with directional channel locking (BDCL), compact pattern based dynamic channel assignment (CPDCA) and compact Pattern with maximized channel borrowing (CPMCB) in various uniform and nonuniform traffic load distribution, the simulation results indicate that with the increase of traffic load,the system average blocking Probability of CPCB is lower than those of FCA,BDCL,CPDCA etc.. Besides,the growth the of the blocking Probability is the lower than that of the above strategies significantly.
