Equipment for testing switch between base stations for mobile terminals

Abstract

The invention consists of a first radiation antenna connected to a first base station and used for transmitting and receiving radio signals, a first shielded cap covering the radiation antenna and remaining an opening, a first gear of shielded cap connected to the first shielded cap and used for driving the first radiation antenna to rotate around the first shielded cap, a second radiation antenna connected to the second base station and used for transmitting and receiving radio signals, a second shielded cap covering the second radiation antenna and remaining an opening, a second shielded gear connected to the second shielded cap and used for driving the second antenna to rotate around the second shielded cap, and a motor used for controlling the rotation of gear. The invention can simulate or replace the manual test on the spot to improve the efficiency of massive test.

Description

technical field [0001] The invention relates to a testing device, in particular to a device for automatically performing a mobile switching test of a mobile phone in a mobile communication system. Background technique [0002] Since the mobile phone is always in a mobile state in the mobile communication network (GSM, PCS, CDMA, etc.), while the base station is in a fixed position, this leads to the need for the mobile phone to switch between the base stations during the communication process. In addition, due to the wireless environment Instability, short-term signal fading will also cause mobile phones to switch between channels, especially for microcellular systems (such as PCS systems, etc.), this switching is more frequent, therefore, handover (including hard handover, soft handover) , softer handover and relay handover, etc.) occupy an important position in the cellular mobile communication system. [0003] For example, a GSM mobile phone transmits call signals with 9...

Problems solved by technology

[0005] However, there is currently no device or instrument specially used for mobile handover testing. In actual testing, two base stations are often found on the spot first. The level coverage between the original standby base station and the target base station must overlap to a certain extent, and There are also certain requirements for the level of the target base station when switching occurs, so that the switching conditions can be guaranteed; then, in order to provide the reliability of the test data, the tester needs to repeatedly move between the two base stations, which is not only time-consuming and labor-intensive, but also Test efficiency is not high

In addition, due to the uncertainty of the wireless environment, it is difficult to reproduce and locate some problems that occurred during the test
