无线蜂窝环境下的统一移动模型及其接纳控制分析

A Uniform Mobility Model and Its CAC Analysis under Wireless Cellular Environment

提出了蜂窝结构下无线通信的一种统一用户移动模型,并给出了该模型下的接纳概率数学表达式.只要从不同的研究角度出发去合并或分解模型的某些参数,常见的几种移动模型都可以由该模型衍生出来.用带宽作为模型的资源参数,克服了以前接纳模型以信道数作为呼叫资源单位这种不适合分析数据通信的缺点.同时还总结了一种方法论思想,对研究系统性问题在思路上可能有所帮助.

A uniform mobility model for sub,scriber in cellular communication is put forward and corresponding mathematic formula for admission probability is given. From such model, general mobility model can be derived by combining or decomposing .some parameters according to different research view. The defect in traditional model due to applying channel number as call resource which is not suitable for data communication analysis is overcome in uniform model by using bandwidth as call resource parameter. A methodological idea is also generalized which may be helpful for researching systematic problems.
