摘要
为了综合利用WLAN与3GPP移动网络各自的优势,3GPP R9定义了3GPP与WLAN网络融合体系架构,并在3GPP与WLAN网间选择中引入接入网发现和选择功能单元(ANDSF)网络选择机制。文章在研究WLAN-3GPP融合参考体系架构与现有ANDSF网络选择机制基础上,分析了基于ANDSF网络选择机制的不足,提出了一种基于用户业务感知与ANDSF相结合的WLAN-3GPP融合架构网络选择方案,为融合架构中3GPP与WLAN网络切换提供了基础,有效提高用户体验与网络控制能力。
Based on the study of converged WLAN- 3GPP reference architecture and the existing ANDSF network selection mechanism, andanalysis oflhe deficiencies of ANDSF network selection mechanism, this paper proposesa kind of network selection scheme which is based on the user service awareness and ANDSF. It provides the foundation for the switchover between 3GPP and WLAN net- work, andcan improve user experience and network control abilityeffeetively.
