Unified Approach for Design Issues in Cellular Communications Networks

我们研究了“轻交通方法”，这是一种解决蜂窝通信系统设计问题的统一方法。我们主要集中在设计蜂窝通信系统的新方法的建议和该方法的验证。“轻型交通方法”的概念很简单。标记呼叫的状态使用双分量随机过程来描述（单元中的客户数量，单元的状态）。我们考虑到随机过程的第一个分量可以用生死过程来描述，而第二个分量很容易用从交通量限制中得到的概率分布来计算。我们将其应用于系统设计中的问题，称为“轻交通方法”。我们已经证实，即使客户有自己的优先事项，我们的方法也是有效的。此外，我们的方法在前端Web系统的设计问题和指数基金的选择问题的应用中也很有效。

We investigated "light traffic approach," which is a unified approach to solving design issue in cellular communications systems. We mainly focused on proposals of a new methodology of designing cellular communications systems and the validations of its methodology. The concept of "light traffic approach" is simple. The state of tagged call is described using two-component stochastic process, (the number of customers in the cell, the state of the cell). We took into account the facts that the first component of the stochastic process can be described by the birth-and-death process, and the second component is easily calculated by using some probability distribution that is obtained from light traffic limit. We apply this to issues in system design as the "light traffic approach".We have verified that our approach is effective even if the customers have their own priorities. In addition, our approach is also effective in applications of design issues in front-end Web system and of selection problems in index fund.
