Abstract

We study the cell performance characteristics for a mobile network in which the user service rate depends on the area of the cell where the user is located. The division of the cell into zones is determined by the signal quality and depends on the distance to the base station and the presence of obstacles and interference for the radio signal. The incoming flow of requests is described by a marked Markovian arrival process, where the request type corresponds to the zone where it is generated. Being served, the requests can move between zones, resulting in a change in their types. The possibility of fluctuations in the flow and service process parameters under the influence of exogenous random disturbances (random environment) is taken into account. The importance of taking into account the dependence of parameters on the state of the random environment and the possibility of using the results for solving optimization problems are numerically illustrated.

考虑随机环境的自适应调制移动通信小区中的客户服务模型

摘要

我们研究了移动网络的小区性能特征，其中用户服务速率取决于用户所在小区的区域。小区划分为区域由信号质量决定，并取决于到基站的距离以及无线电信号的障碍和干扰的存在。请求的传入流由标记的马尔可夫到达过程描述，其中请求类型对应于生成它的区域。请求可以在区域之间移动，从而导致它们的类型发生变化。考虑了外源随机扰动（随机环境）影响下流量和服务过程参数波动的可能性。
