在IP移动通信中，越区切换是影响移动的通信质量的关键问题之一。为了解决这个问题，已经提出了许多网络选择方法。提出了一种切换和多归属时的网络选择方法，以提高IP移动通信质量。为了选择最佳的网络接口或通信介质，需要获得诸如传输延迟时间和分组丢失率的QoS标准。移动的节点本身可以测量实时网络状态以获得准则，或者移动的节点可以获得存储在因特网上的任何数据库中的统计信息。虽然准则收集方式对网络选择影响很大，但在现有的研究中并没有详细讨论。本文的目的是考虑不同类型的网络选择标准的观点对IP移动通信质量的影响。为此，我们首先设计并实作两个原型系统，以取得不同类型的准则。一个是测量移动的节点本身中的实时网络状态的功能。另一种是通过互联网获取数据库中存储的统计信息。其次，我们通过一些现场实验对这两种准则进行了比较。对于实验，我们还实现了一个原型系统，使用这两个功能，在我们提出的IP移动性架构。通过实验评估，我们展示了定量比较两种类型的网络选择标准的QoS所需的一些应用程序的满意率。
In IP mobility communications, handoff is one of critical points degrading mobile communications quality. To solve this problem, many network selection methods have been proposed. We also proposed a network selection method in handoff and multi-homing to improve IP mobility communications quality. To select the best network interface or communication medium, it is required to obtain QoS criteria such as transmission delay time and packet loss ratio. The mobile node itself may measure real-time network status to obtain the criteria, or the mobile node may obtain statistical information stored in any database on the Internet. Though the criteria collection way affects much on network selection, it is not discussed in detail in the existing research. The purpose of this paper is to consider the difference types of network selection criteria from the viewpoint of effects on IP mobility communications quality. For this purpose, we first designed and implemented two prototype systems to obtain the different types of the criteria. One is a function to measure real-time network status in a mobile node itself. The other one is to obtain the stored statistical information in the database on the Internet. Next, we compare the two kinds of criteria by some field experiments. For the experiments, we also implemented a prototype system using both functions in our proposed IP mobility architecture. Through the experimental evaluations, we showed quantitative comparison of two types of network selection criteria by satisfaction ratio of QoS required by some applications.
