Problems solved by technology

[0003] The SCDMA system is a TDD code division multiple access system, which is different from GSM, IS-95 or CDMA2000. Currently, there is no drive test product for the SCDMA system on the market. In order to test the relevant parameters of the network performance simultaneously, and simultaneously An effective SCDMA network drive test device and method are needed for the multi-serial port problems and long-term drive test power supply problems brought about by testing network performance parameters.

Embodiment Construction

[0025] figure 1 Shows the hardware structure of the drive test device of the present invention, wherein the GPS module is converted from TTL to RS232 level by the interface conversion circuit, and then communicates with the notebook via USB to multiple serial port devices with multiple mobile phones; multiple mobile phones and GPS are connected by The power conversion circuit uses the 12V car cigarette lighter as the power supply to supply power to them respectively. In addition, multiple test mobile phones can also share one antenna and attenuator through a power divider, and place the antenna together with the GPS antenna on the roof of the vehicle.

[0026] In order to further simplify the connection of the test device and facilitate the carrying of the test equipment, it is also necessary to design a practical outer box for the drive tester. The outer box contains all components except the notebook. When in use, the notebook is placed beside the tester, and the cabinet c...

Abstract

The apparatus comprises: at least one testing mobile phone; a GPS module; a power switch module for connecting the testing mobile phone to the GPS module; a PC; an interface switch module; a USB to multi-port serial adapter; and a test module. Wherein, the testing mobile phone and the interface switch module are connected to the USB to multi-port serial adapter through RS232 interface; the GPS module is connected to the interface switch module; the USB to multi-port serial adapter is connected to the USB port of PC; the test module uses parallel mode between auxiliary thread and main thread; the auxiliary thread informs the main thread to refresh the interface by sending a message; the main thread controls the beginning and ending of the auxiliary thread to implement call test, and meanwhile make the coverage test and scan test.

Description

technical field [0001] The invention relates to a drive test device and method for network performance testing of a wireless communication access system, in particular to a SCDMA network drive test device and method. Background technique [0002] The current wireless network drive test is generally completed by a drive tester, which includes a display function unit, a storage function unit, a processing function unit, and a data terminal equipment (DTE). Specifically, its display, storage, and processing functions are realized by a notebook computer or a PDA, and the DTE is a test mobile phone and a GPS receiver. The drive test software is installed on the laptop to collect, process and display the data. The test mobile phone is an off-the-shelf product of the purchased manufacturer. The method of the drive test is to select the test route, connect each device, record the data, and finally perform post-processing of the data. [0003] The SCDMA system is a TDD code divisio...
