WLAN技术在软交换系统中的应用

Applications of WLAN in Softswitch

文章主要讨论无线局域网(WLAN)如何接入软交换系统,通过对WLAN技术标准、网络架构及承载能力的探讨,揭示了软交换系统无线应用面临的挑战,在此基础上给出了一些有前景的应用,如VoWLAN、远程无线监控、无线即时消息和定位服务等的解决方案。文章认为宽带无线接入标准WiMAX有望成为WLAN的升级版,一旦成熟,并与软交换等NGN技术相结合,将会实现人们追求的“网络无所不在,信息随手可得”的美好愿望。

How to access a Softswitch system for WLAN is focused in the paper. Based on the analysis of technical standards, network architecture and carrying capacity of WLAN, challenges to wireless applications in Softswitch systems are discussed. Solutions related to promising wireless applications, such as VoWLAN （Voice over WLAN）, remote wireless monitoring, wireless instant messaging, and location-based services, are presented. It is concluded that WiMAX, as a broadband wireless access standard, may become the successor of WLAN. When matured and combined with Softswitch and other NGN technologies, it will make people＇s good wishes of ＇Access Network Anywhere, Get Information Anytime＇ come into true.
