摘要
如何将会话初始化协议(SIP)与现有的通信网络有机结合,提供安全可靠的数据及通信服务已成为当今的热点问题。VoIP应用也受到业界的持续关注。安全问题一直都是企业实施VoIP的一个阻碍。提出了一个基于SIP的VoWLAN通信平台,将各种语音服务构建于无线局域网之上。利用虚拟专用网(VPN)、数据加密技术、VLAN和防火墙等必要安全技术和策略,应对在系统中的安全威胁,实现了通话质量可靠、安全性高的企业级VoIP无线网络架构。描述了该系统的设计和实现过程,讨论了其中的关键技术。
How to combine Session Initiation Protocol （SIP） with current communication system well so as to provide secure telecommunication services has become a hot current issue. Security issue is always the major barrier to employing Voice over Internet Protocol （VolP） technology by enterprise. This paper presented a solution named VoWLAN for voice business over Wireless Local Area Network （WLAN） on the basis of SIP server and VoIP gateway which deploys various voice services. Virtual Private Network （VPN）, data encryption, VLAN and firewall technique achieved good quality and safety enterprise VoIP platform were implemented, and the design and implementation procedure of the whole system were described.
