【摘要】：随着时代的发展和移动智能终端的快速普及,人们对无线网络的访问需求越来越大。但是,由于速率低、资费高、不能跨网使用、部分终端无法接入等原因,使得3G网络经常不能满足使用需求,而WLAN网络由于速率高、资费低廉甚至免费等优点,受到用户的青睐。然而,WLAN网络由于覆盖范围小、也不支持用户跨网使用等缺点,致使用户在使用移动网络时,经常在3G网络与WLAN网络之间频繁的手动切换,严重影响用户体验。MiFi(MobileWiFi)的出现恰恰解决了这些问题。本文主要研究了MiFi接入3G网络和WLAN网络技术,并重点设计与实现了3G网络与WLAN网络之间的相互切换算法。使MiFi在满足方便使用、组网灵活、安全性高的同时,屏蔽了外部网络的差异,能够根据预设算法,优先使用3G网络或WLAN网络,并且具有动态切换的特性。本文在3G与WLAN网络相互切换的前提下,提出一个具有实用性、灵活性和便捷性的新功能,使MiFi能够充分利用3G网络的广泛覆盖和WLAN的高速率与低资费,为MiFi产品增加新的应用亮点,并且经过试验表明此功能可用。
[Abstract]:With the development of the times and the rapid popularization of mobile intelligent terminals, people need more and more wireless network access. However, due to the low speed, high tariff, can not be used across the network, some terminals can not access, and so on. The 3G network is often unable to meet the needs of the users, but the WLAN network is favored by users because of its high speed, low tariff and even free. However, because of its small coverage, it does not support the cross-network use of users. When users use mobile networks, they often switch frequently between 3G networks and WLAN networks, which seriously affect the emergence of user experience .MiFiFiileWiFi. this paper mainly studies the technology of MiFi access to 3G network and WLAN network. The switching algorithm between 3G network and WLAN network is designed and implemented in detail, which makes MiFi meet the requirements of convenient use, flexible networking and high security, while shielding the differences of external network, which can be based on the preset algorithm. 3G or WLAN networks are preferred to be used and have the characteristics of dynamic handoff. In this paper, a new function with practicability, flexibility and convenience is proposed under the premise of switching between 3G and WLAN networks. So that MiFi can make full use of the wide coverage of 3G network and the high rate and low tariff of WLAN, and add new application bright spots for MiFi products, and the experiment shows that this function is available.
