The direction of development of mobile communication technology is diverse, broadband, WCDMA 3GPP R5, R6 specification, the introduction of HSPA downlink rate can reach 5.76Mbit/s and 14.4Mbit/s. HSPA+technology of HSPA Evolution version, it can theoretically 22 Mbit/s and 42 Mbit/s uplink and downlink data transfer rate. At present, the global mainstream operators to deploy HSPA

TD-SCDMA standard is one of three international3G standards, which is raised by China independently. Since the standard has been accepted by the International Telecommunication Union (ITU), it has got continuous improvement and development so far. With the rapid development of smart terminals, the demand for telecommunications service is no longer the simple voice communication, but

This thesis gives a deep analysis on HSDPA transmissionperformance. It is generated under the background when China Mobilebuilds up the TD-SCDMA mobile network. Some regions received baddata transmission rate under the on field test. From the aspect of radiotransmission characteristic, this problem lies in worse transmissionperformance in AP (Application Layer). Therefore, proper solutionsshould be taken
