WiMAX接入核心网络中的数据通道技术

Data Path Technology in WiMAX Access Core Network

近几年来,无线通信技术飞速发展,宽带技术无线化是宽带通信发展的趋势。作为一种宽带无线技术,WiMAX因其传输速率快、传输距离远、具有QoS保障、安全性能好等优点,在"最后一公里"接入技术中占据非常重要的地位。在WiMAX接入核心网络中,数据通道技术就是完成基站、网关间的数据传输,是基站和网关中一个不可缺少的功能模块。详细介绍了数据通道的建立、修改和删除过程以及在几种典型场景中的应用。

With the rapid development of wireless technologies during recent years, the broadband wireless technology comes to be one of the trends of broadband communication. WIMAX, as a kind of broadband wireless technology, plays an important role in ＂last mile＂ access due to its fast rate, long-distance transport, guaranteed QoS and security, and so on. In WiMAX access core network, DP （data path）, used for data transfer between BSs, GWs, and between BS and GW, is a basic function module in GW and BS. This paper introduces the registration, modification and release of DP in detail, and application in several typical scenes.
