在本文中，我们提出了一种无线系统发现方案，能够支持有效的设备电源管理，采用电池效率的无线网络扫描过程。多模式终端必须能够发现其它无线系统，并且最重要的是，在异构无线网络环境中执行系统间切换。在最近的研究报告中介绍的现有方法具有某些缺点，例如由频繁的调制解调器激活引起的增加的电池功耗，或者多模终端不能迅速发现无线系统。我们提出了一种方案，其中多模终端能够发现其他无线系统比以前的计划更快，更准确，同时消耗最低水平的功率。我们还证明了该计划提供了更好的性能值，通过比较它与现有的计划。
In this paper, we propose a wireless system discovery scheme capable of supporting effective device power management by employing a battery-efficient wireless network scanning procedure. Multi-mode terminals must be able to discover other wireless systems and, above all, to execute an inter-system handover in the heterogeneous wireless network environment. The existing methods introduced in recent research reports have certain shortcomings, such as increased battery power consumption occasioned by frequent modem activation, or the inability of the multi-mode terminal to promptly discover wireless systems. We propose a scheme in which multi-mode terminals are able to discover other wireless systems more quickly and accurately than previous schemes, while consuming minimal levels of power. We also prove that the scheme offers better performance values by comparing it with the existing schemes.
