Abstract

The invention discloses a method and device for detecting the quality of a communication system based on a sweep generator, and the method comprises the following steps: using the sweep generator to acquire frequency points of a disturbed cell and cell parameter identifier (CPI) information which are provided by testing software; synchronizing to the disturbed cell according to the information of the frequency points of the disturbed cell and the CPI information; detecting a downlink synchronization code corresponding to the synchronized disturbed cell, and determining an uplink pilot time slot (UpPTS) window according to the downlink synchronization code; sweeping the downlink synchronization code corresponding to a disturbing cell scanned by the UpPTS window, and synchronizing to the disturbing cell according to the downlink synchronization code; and detecting cell identification information corresponding to the synchronized disturbing cell, and determining the disturbing cell according to the cell identification information. According to the technical scheme, UE (user equipment) with the use of a downlink traffic channel can be detected on the basis of the sweep generator, the quality of the UE with the use of the downlink traffic channel can be determined, and the accuracy of detection of the quality of the communication system can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting the quality of a communication system based on a frequency scanner. Background technique [0002] In the TD-SCDMA (TimeDivision-Synchronous Code Division Multiple Access) system, one of the 3G network standards defined by the 3GPP organization, the frequency scanner is a wireless network planning and network optimization device. Special equipment, it is mainly used for base station site survey and propagation model correction before the construction of TD-SCDMA wireless network. After the network construction is completed, it can measure the wireless transmission characteristics between the base station and the terminal, and can complete the TD-SCDMA network accurately and quickly. The measurement and recording of wireless radio frequency signals provide network optimization engineers with interference analysis and coverage analysis of wir...
