由於工商進步，無線通訊的需求日益的增多，現存的無線通訊系統已經無法滿足未來的需要。為了增加單位面積的系統容量以符合未來的需要，而PCN（Personal Communication Network）正逐漸朝這個目標邁進。由Ming Kang Liu教授所提的BSN (Base Station Network)網路架構，是相當符合PCN的精神與目的。
本篇論文是以BSN的網路架構為基礎，研究它在一定的呼叫率、頻道的數目、和服務下，整個BSN的總體阻塞率變化的情形。在有限的無線頻道中，提出如何降低BSN的阻塞率，我們調整一些參數使總體阻塞率下降，以達到增加系統的使用率。
第二個探討的是BSN管理區域會對統造成何種影響？若在BSN要與其他BSN建立呼叫時，中心局間彼此通訊所需要的跨越次數與BSN所管理的區域大小成何種關係？結論是BSN管轄的區域越小時跨越的次數多。
第三個研究的方向是，在BSN中若改變細胞面積的大小時，將會對系統容量產生何種影響？因為細胞面積越小時交遞的次數也越多相對會影響無線頻道的使用率。將針對交遞會對系統容量造成何種影響，並以數學式是表示其關係。

Owing to the progress of industry and business, the requirement of wireless communication gradually increase. Current woreless communication system can not satisfy the requirement in the future. In order to increase the capacity of comunication, PCN (Personal Communication Network) is developed recently. The BSN.(Base Station Network) proposed by Ming Kang Liu Just meets the purpose of PCN.
This study focuses on BSN. We try to know the diversity of the total blocking probability under the condition of constant arrival rate, quantity of the channel, and service rate.
First, we try to decrease the blocking of BSN by adapting some parameters in order to increase the usage ration of the system.
Second, we discuss the effect of zone on the system, what relation exist between the zone of BSN and the crossing numbers of communication for central offices if a BSN wants to call other BSNs.
Third, if the area of a cell is changed, what effect on the system will occur? The frequency of handoff is larger when the area of a cell is smaller the will affect the usage ratio of the wireless channel.
