Equipment stability testing method and device

Abstract

The invention discloses an equipment stability testing method and an equipment stability testing device, which are used for controlling the output of a global positioning system (GPS) clock according to the requirements of a user, thereby performing a system-level test in the tolerance of time division (TD)-long term evolution (LTE) system equipment under unstable clock condition, determining the stability of the equipment and further improving the stability of the equipment in an actual application process. The equipment stability testing method provided by the invention comprises the following steps of: outputting a GPS clock signal to the equipment to be tested according to a value of a clock switch selected by the user and a preset value of a counter used for counting the number of local clock cycles in each GPS clock cycle; and counting the service success rate of the equipment under the GPS clock signal, and testing the working stability of the equipment under the unstable clock condition according to a counting result.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for testing equipment stability. Background technique [0002] Time Division Synchronized Code Division Multiple Access (TD-SCDMA) is a strictly synchronous system, and the Global Positioning System (Global Positioning System, GPS) clock synchronization system in the base station (Node B) system is the entire An important part of the synchronization system. Strict GPS synchronization can guarantee the function and performance of the system and effectively reduce interference. [0003] The current solution tends to integrate the time service of the Beidou system and the GPS system to achieve better utilization of existing clock system resources. The current general solution principle is as follows figure 1 As shown, the outdoor clock unit (Outdoor Clock Unit, OCU) in the figure is an integrated timing module of the Beidou system and the GPS system. I...

Problems solved by technology

However, whether the protection is reasonable and effective, there is no effective means to test at the system level, at most only through single board testing or unit testing

If the clock protection is insufficient and not tested, it will cause some base stations in the live network to work abnormally, and problems may occur in handover, voice quality, connection rate, call drop rate, data service rate, etc., and the positioning of this part is extremely difficult
