【摘要】 随着无线移动通信技术的发展,Wi-Fi手机成为了市场上的一个新兴热点。Wi-Fi手机是在以无线局域网(WLAN)和因特网(Internet)为基础的未授权移动接入(UMA)网络环境下支持IP电话(VoIP)功能的手机。Wi-Fi手机的优势首先在于它可以在已经连接上因特网的AP(Access Poing)的覆盖区域内,通过与当前可用AP建立普通Wi-Fi链接来达到浏览互联网的目的,这种浏览方式是免费的且速度相较GPRS链接而言更快,更稳定。其次,Wi-Fi手机可以在以因特网(Internet)为基础的未授权移动接入(UMA)网络环境下建立带安全功能的Wi-Fi链接,即在这个链接里可以采用IPSec技术保证整个UMA通信网络的安全性。论文主要工作包括:1.分析和研究Wi-Fi技术及其现状和发展前景。2.分析和研究IPSec相关协议包括认证头协议(AH)、封装安全载荷协议(ESP)以及密钥交换协议(IKEv2),掌握了IPSec的体系结构和工作机制。3.在深入研究普通Wi-Fi链接和带安全功能的Wi-Fi链接的处理逻辑后,设计并实现了适用于Wi-Fi链接处理逻辑的链接管理模块。论文在Linux内核的手机系统上,通过实现以Wi-Fi链接为基础的数据管理模块及其处理逻辑,管理控制在Wi-Fi手机中存在的两种Wi-Fi链接。论文的研究成果已在Wi-Fi手机产品中得到了应用,并取得了良好的效果。更多还原

【Abstract】 As the development of the wireless mobile communication technology, Wi-Fi mobile phone becomes a new highlight in current markets. Wi-Fi mobile phone is based on the Wireless LAN and Internet, under the unauthorized mobile access network environment, supports IP telephony by VoIP. The advantage of the Wi-Fi mobile phone lies in two aspects:Firstly, with the function of capable to establish ordinary links with the covering region of internet through AP, Wi-Fi mobile phone can achieve the goal of surfing the internet, this linking is charge free, and in terms of speed it is faster and more stable than GPRS links.Secondly, based on WLAN and Internet , Wi-Fi mobile phone can establish a security protect functional linking, under the unauthorized mobile access network environment, namely, it can guarantee the security of entire UMA telecom network by IPSec.The main works of the dissertation includes:1. Analysis and research Wi-Fi technology, and its status and development prospects.2. Analysis and research related agreements including IPSec authentication first agreement (AH) and Encapsulating Security Payload Protocol (ESP), and Key Exchange Protocol (IKEv2), got mastered the IPSec architecture and working mechanisms.3. After In-depth study of the Wi-Fi link processing logic for the general Wi-Fi link and the link with security features, designed and implemented the linking management module to deal with Wi-Fi links.This dissertation manages and controls the two Wi-Fi link in Wi-Fi phones through the realization of a Wi-Fi link-based data management and processing logic modules in the Linux kernel phone system .The research results have been applied in the Wi-Fi phone products and have achieved good results.更多还原
