| 摘 要： | TCP在TD-HSUPA系统中的表现不理想,需要采取一些优化措施,在分析了TD-HSUPA系统的网络协议结构之后,提出了一种适用于TD-HSUPA系统的TCP优化方法--由RNC解析终端TCP连接的状态,在终端可能出现超时之前,由NodeB通过调度和信道分配相结合的方法改变终端物理层网络环境.经仿真表明,对于复杂多变的...

| Abstract: | Due to the poor performance of TCP over TD-HSUPA system,so it needs to take some optimization measures.This paper analyzes the TD-HSUPA network structure and proposes a solution to enhance the TCP performance,the optimization measure is that RNC analyses the TCP state of UE and informs NodeB to adjust the UE′s physical channel by scheduling and DCA(dynamic channel assignment).The simulation shows that the method mentioned above can guarantee TD-HSUPA data transmission stability and improve network utilization and throughput in the complex wireless air interface environment. |
