Abstract

The invention discloses a method, a device and a system for testing the coverage performance of a network. The method comprises the following steps of: acquiring an initial time division-synchronous code division multiple access (TD-SCDMA) origination received signal code power level value and TD-to-second-generation (2G) network voice service switching frequency; computing and generating a weak-field origination ratio according to the initial TD-SCDMA origination received signal code power level value; judging whether the weak-field origination ratio exceeds a preset weak-field origination threshold value or not, and computing and generating a TD-to-2G network voice service switching frequency ratio according to the TD-to-2G network voice service switching frequency if the weak-field origination ratio does not exceed the preset weak-field origination threshold value; and judging whether the TD-to-2G network voice service switching frequency ratio exceeds a preset switching frequency threshold value or not, and determining that the network coverage performance of a base station is low if the TD-to-2G network voice service switching frequency ratio exceeds the preset switching frequency threshold value. By the method, the device and the system provided by the embodiment of the invention for testing the coverage performance of the TD-SCDMA network, the coverage performance of a TD network can be comprehensively reflected without the influence of the switching frequency, and manpower and material resources can be saved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the field of TD-SCDMA mobile communication, and specifically relates to a test method, device and system for TD-SCDMA network coverage performance. Background technique [0002] Because the TD-SCDMA system uses a frequency band of about 2 GHz, compared with the GSM system, the space loss is large and the penetration ability is weak. Moreover, the TD network is in the initial construction stage, and the network coverage needs to be continuously improved. There are three existing methods for judging TD-SCDMA network coverage performance: [0003] 1. Using a large number of road and fixed-point tests, by testing the terminal, the received signal code power (RSCP) of the primary common control physical channel (Primary Common Control Physical Channel, PCCPCH) of the base station is used to measure the TD-SCDMA network coverage performance. The measurement standard for the covera...
