摘要： 对曾提出的基于效用函数的无线接入网络选择机制作了进一步分析和说明，不同于只考虑两种因素的传统方法，它致力于在一个简单框架下兼顾对未来城市道路网多媒体业务有重要意义的多种因素.改进了选择算法, 并基于该选择机制开发出一个模拟工具雏形.

Abstract: A utility based network selection scheme having been formerly proposed by us was explained and analysed furtherly. Different from a traditional scheme only considering two factors, our scheme took more factors important for multimedia application in future urban road heterogeneous wireless access networks into account within a simple framework. The selection algorithm was improved and a rudimental simulator was developed.
