摘要
随着移动互联网业务的高速发展,用户对随时随地高速接入带宽的需求迅速增长,对无线接入网的灵活覆盖和数据传输带宽提出了严峻挑战。为了解决此问题,提出一种基于LTE技术和Wi-Fi技术融合的宽带无线接入网组网方案。方案以LTE实现远距离高带宽数据通信,以Wi-Fi实现近距离高带宽数据通信,LTE和Wi-Fi数据包在双模终端处实现两种协议的转换,从而实现双模终端远距离(LTE)和近距离(Wi-Fi)灵活覆盖以及高速数据传输。在双模终端和LTE基站端根据不同的QoS参数实现不同数据业务的不同优先级;采用基于软件无线电技术(SCA)的通用硬件平台,分别加载LTE基站和双模终端协议栈软件,实现不同模式的无线网络设备的接入功能,在缩短开发周期的同时,大大降低了硬件开发成本。
With the rapid development of mobile Internet services, users’ demand for high-speed access bandwidth at any time and anywhere is increasing rapidly, which poses severe challenges to the flexible coverage and data transmission bandwidth of wireless access networks. To solve this problem, a networking scheme of broadband wireless access network based on the integration of LTE and Wi-Fi tech nology is proposed. In the scheme, LTE is used to realize long-distance high-bandwidth data communi-cation and Wi-Fi is used to realize short-distance high-bandwidth data communication. LTE and Wi-Fi data packets are converted between the two protocols at the dual-mode terminal, thus realizing the flexible coverage and high-speed data transmission of long-distance(LTE) and short-distance(Wi-Fi) of the dual-mode terminal.At the dual-mode terminal and LTE base station, different priorities of different data services are realized according to different QoS parameters;the general hardware platform based on software radio technology(SCA) is adopted, and the LTE base station and dual-mode terminal protocol stack software are loaded respectively to realize the access function of wireless network equipment in different modes, which shortens the development cycle and greatly reduces the hardware development cost.
