[0029] Example
[0030] When using the method of the present invention to carry out the drive test to the TD-LTE system on the spot, its process is as follows figure 1 shown, including:
[0031] Step S1: Arrange the test terminal on the public transportation in the service area, and the specific steps are as follows figure 2 As shown in the figure, the tester first determines the test route of the road test, and then installs a certain number of test terminals on the public transportation passing the test route, the number of which is proportional to the population density of the service area and the usage of the TD-LTE system, Its operating routes are mainly general roads.

The invention relates to a stratification testing method and a device for time division long term evolution (TD-LTE) system road testing. The stratification method comprises the following steps: conducting network optimization from the perspective of user perceptibility; installing testing terminals on public transport means; controlling the testing terminals by analysis control equipment to test; grading user perception marks and evaluating the user perception marks; obtaining the user perception marks; generating a testing report; submitting the testing report to the analysis control equipment; screening out the testing report which is lower than the user perception mark threshold by the analysis control equipment; positioning the key quality indicators which cause a low user perceptibility according to the testing report and the mapping relation between the user perception evaluating indicators and the key quality indicators; and further positioning key performance indicators which cause the low user perceptibility. The stratification testing device comprises the analysis control equipment and the testing terminal which is composed of a receiving unit, a service testing unit, an evaluating unit and a reported unit. Compared with the prior art, the stratification testing method and the device for the TD-LTE system road measurement have the advantages of reducing the number of testing staff participating with the road testing work, being time-saving and effort-saving, and improving the efficiency and the accuracy of road testing.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a layered test method and device for TD-LTE system drive test. Background technique [0002] With the increase of mobile users, the continuous expansion of the network scale, the continuous change of the wireless communication environment, the continuous change of the distribution of mobile users, the sharp reduction of mobile terminals and tariffs, and the increasing requirements of mobile users on the quality of mobile networks, and the The competition among various telecom operators in the world is becoming more and more fierce, and mobile network planning and network optimization have become the top priority for each telecom operator to survive and develop in the fierce competition. A good communication network is the basis for high-quality communication for users, and it is also the guarantee for telecom operators to obtain good economic and social benefits. ...
