WLAN与LTE网络融合部署研究

Study on the Interworking Deployment of WLAN and LTE

在对WLAN与LTE网络之间6种互通场景描述的基础上,分析比较了3GPP所提出的3种WLAN和LTE融合架构方案;结合目前公众WLAN网络的部署方式,给出了WLAN与LTE融合方案的选择建议,并基于S2a接口方式的WLAN与LTE融合网络架构,分别从网络设置、业务数据流向、接入认证方式、认证数据流向、网络发现和选择、系统间切换机制选择等方面进行分析,最后给出了融合部署建议。

Based on the description of six interworking scenarios between WLAN and LTE, it compares the three types of interworking ar-chitectures between WLAN and LTE suggested by 3GPP. Combined with public WLAN network deployment, it gives the inter-working proposals. Based on the S2a interface interworking scheme, it analyzes the network settings, service data flow, ac-cess authentication mode, authentication data flow, access network discovery and selection, and inter-system handover mechanism selection, and puts forward the interworking deployment proposals.
