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 introduces a new dynamic channel assignment strategy in Cellular Mobile Communication System ─ ─ Compact Mode Based Channel Borrowing Assignment Strategy (CPCB). This strategy not only has the advantages of dynamic channel assignment based on compact mode, but also has the advantage of channel borrowing in the fixed channel assignment strategy. The authors simulate the new algorithm in a commonly used 49-cell cellular communication network and compare the service distributions of several homogeneous and non-uniform modes respectively. The results show that the average blocking rate of CPCB is lower than FCA, BDCL, CPA-based DCA and CPMCB. With the increase of load, the growth rate of the average blocking rate of the system is also significantly lower than the above strategies.
