Description

technical field [0001] The invention relates to a wireless network test system, in particular to a general field wireless test system. Background technique [0002] At present, diversified business content, excellent network performance and high service quality in mobile communication are the focus of the development of the mobile communication industry, and wireless network field testing is one of the effective ways to collect and examine various performance indicators of wireless network. Traditional wireless network field testing mainly refers to two types of field testing: specific testing and drive testing. [0003] A specific test is usually to build a special test environment for a specific test project. Due to the constraints of the optional environment, geographical location, equipment, etc., the adaptability and accuracy of the test environment built are relatively poor. The establishment and adjustment of a more complex network environment not only consumes a lot...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the field test is usually carried out in a real network environment, the change of the network environment makes the test environment lack continuity and stability, and is greatly disturbed by the external network. For the test, the harsh network environment will make the test results produce immeasurable error;

[0005] (2) Since the test environment is often only applicable to certain specific test items, the realized network environment is relatively single, which can neither simulate the network conditions under the coexistence of multiple networks, nor adapt to other test items, and the use and allocation of resources exist. huge waste

[0007] (1) Existing drive test methods cannot test high-speed mobile terminals in wireless network environments, such as terminal operating status tests in high-speed train environments;

[0008] (2) The current drive test is difficult to realize the coexistence of multiple wireless environments, so it is not yet possible to perform test items such as switching between multiple wireless systems;

[0009] (3) The drive test method is more about finding problems. It can neither reproduce network problems nor find solutions to problems through device adjustments and parameter settings.
