无线网络中的无缝漫游实现方法

无线广域网(WWAN)与无线局域网(WLAN)都是近期发展比较成熟的无线网络,将它们很好的结合,是下一代网络(NGN)发展趋势与主题。使用虚拟用户识别模块(SIM)卡认证是在SIM/用户服务识别模块(USIM)模式基础上提出的一种可行性设想,利用蓝牙技术组成无线个人通信网,快速找到虚拟SIM,不需要通过繁复的设置认证,通过把通信任务和进程从应用处理中分离出来,加速了针对无缝漫游新应用的创新。

As well-developed wireless networks in recently days, it has become the development trend of next generation network （NGN） that WWAN and WLAN are combined effectively. Authentication by using virtual SIM card is a feasibility plan based on SIM/USIM mode. The technology can find virtual SIM card easily by using Bluetooth WPAN without complex authentication. The mission and process of communication are divided from application processing to accelerate the creative of new applications for wireless roaming.
