摘　　要：本文针对使用TD-HSDPA系统进行大容量文件FTP下载过程中出现的断流问题进行分析,通过对比测试和信令抓包等手段,定位到TCP协议中MSS设置对断流现象产生的影响,通过修改Gi口防火墙的MSS设置解决了该问题,最后提出尚待跟进的几个问题。This article aims at analyzing the problems of breaking off during FTP downloading large size files using TD-HSDPA. Through testing in different environment and capturing packets, the initial reason of FTP data stream broken off was found, which is the setting of MSS that coursing the broken-off of FTP data stream. Setting the value of MSS in the Gi firewall can temparorily solve the problem, but the real reason is still to be found, and some other problems are still remained to be solved
