摘　　要：通过对广东联通全省3G数据网络性能指标进行的监控分析发现,目前HSPA+(64QAM)应用比例不高,无法有效体现高速移动网络的优势,以及无法进一步提升用户的移动上网感知。为此,通过对省内3个主设备厂家的网络进行试点,重点对HSPA+功能启用的各种制约因素进行分析研究,由此提出针对HSPA+网络的性能提升方案,后续在全省进行应用推广,取得了良好的优化效果,对HSPA+/DC网络性能优化具有较大的指导意义。It first analyzes the performance index of Guangdong Unicom 3G data network, gets the conclusion that the application propor-tion of HSPA＋is low and the advantage of high-speed mobile network can not be shown, the mobile user perception can not be improved. Taking emphasis on analyzing restricting factors on commissioning HSPA＋, the networks of 3 main equipment enterprise are tested, thus the performance improving solution on HSPA＋network is presented and be applied in Guangdong province. The results is shown wel and is significant for optimizing HSPA＋/DC network performance.
