摘要

本文提出一种新的动态信道分配策略

称之为分级紧致的动态信道分配(

CCDCA

)

所谓分级就是基于引入的"冷态"和"热态"的概念

将小区所处的状态分为冷态与热态;所谓紧致就是对处于不同状态的小区给出不同的紧致模型.该策略在对"热态"的处理过程中利用了"冷态"的先验信息

有机地结合了局部信息与整体信息

同时能保证小区间有较小的服务偏差

提高了整个系统的服务质量.文中还从理论上给出了冷、热态阈值的分析模型

计算出了模型的主要参数

该模型也可以用来分析系统性能.仿真结果证明该方案有较小的呼阻率和较高的频谱利用率

所提出的模型比较接近实际系统.

Abstract

The paper presents a novel channel assignment scheme

namely classified compact dynamic channel assignment (CCDCA) scheme for cellular mobile communications systems.The so-called classification is that a cell is classified as the hot and cold based on the definition of "cold" and "hot".The so-called CCDCA is that different compact strategies and allocation are thus derived

then the information obtained from the previous "cold" state is used for channel assignment in the "hot" state.The scheme combines local information with the whole

and can guarantee high quality of service (QoS) and low service deviation (SD).A two-dimensional Markov chain model is developed to analyze the threshold and its main parameters are derived for the scheme

though it is also applicable to analyze channel assignment schemes.By simulation

the CCDCA is shown to be superior in terms of call blocking probability and spectrum utilization.The simulation also shows that the model can match practical system quite well.
