HWN怎么记

It is well accepted by both the industrial circles and the academic circles that 4G should be an open network environment-heterogeneous wireless networks ( HWN), which can intelligently integrate the existing and the future radio access systems.

业界和学术界人士普遍认为，下一代无线通信系统应该是一个能够将现有的和未来将要出现的各种无线接入系统有机地融合在一起的开放式的异构无线网络。

Secondly, we give the parameters needed for interface selection in HWN. It needs a generic valuation function for various parameters, so we propose DWMIS, which can integrate various parameters.

然后，给出了在异构无线网环境下选择最优接口需要考察的参数，多种参数需要一个统一的评价指标，提出了综合各种参数的评价函数和计算方法DWMIS。

Firstly, we analyzed the security threat and requirements in HWN, and introduced the characters, architecture and security authentication method of two wireless networks 3G and wireless LAN ( WLAN).

首先，分析了无线网络存在的安全威胁以及安全需求，介绍了3G和无线局域网两种无线网络的特点、体系结构以及安全认证方法。
