specific Embodiment approach 1

[0018] Specific implementation mode one: (refer to attached Figure 1~4 ) The optimization processing method of the signal test data in the wireless network planning of the present embodiment is carried out according to the following steps:

[0019] 1. Import the drive test LOG data into the database, and record the sampling points as N i , i=0, 1, 2, ..., n;

[0020] 2. Take the sampling point N 0 as a starting point;

[0021] 3. Connect the starting point and the following sampling points respectively, and record the slope of each connection as K 1 、K 2 、K 3 ,, K 4 , ...; first calculate K 2 -K 1 and judge whether the absolute value is less than the error value M, if not, then N 2 is the sudden change point of the slope; if it is established, then use the following K 3、 、K 4 ,...,K i , ... to calculate K in turn i -K 1 and judge whether its absolute value is less than the error value M, until K is found i -K 1 The absolute value of is less than the error valu...

Abstract

Disclosed is a method for optimization processing of signal test data in a wireless network plan. The invention relates to a method for optimization processing of big data, and solves the technical problem that accuracy of a method for optimization of road test data in the prior art is poor. The method comprises: importing road test LOG data into a processor; marking sampling points; taking a first sampling point as a start point at first; comparing the slopes of lines connected the base point and the other sampling points until a slope abrupt change point is found; storing a line segment from the base point to the slope abrupt change point into a database; traversing all sampling points between the start point and the end point of each line segment to find an inflection point; dividing the line segment with the inflection point; and performing secondary storage of new line segments to obtain a new database, and completing optimization. According to the invention, a geometric and structural characteristic of a connection line between sampling points is utilized to optimize the road test data, and enables the road test data to be effectively combined with a live map and base station information. The method is used for the network plan, and accurate display of road test data is realized.

Description

technical field [0001] The invention relates to a method for optimizing processing of large data Background technique [0002] The pros and cons of a wireless communication network are judged by the effect of users using terminals for various services, while wireless network engineers use drive test data (road mobile communication network signal test data) to evaluate the performance of wireless communication networks. The acquisition of data must first plan the test route, and then collect the data with a sampling period of 500 milliseconds and the receiving power of the mobile station as an indicator, because the drive test data is hundreds of millions of levels, and each sample in the drive test data The attribute values ​​of the points are different, and the frequency and frequency of the sampling points with different attribute values ​​are irregular. It is very time-consuming and laborious to display such huge and disorderly data on the computer map, and it cannot be d...
