A method for carrying out LTE frequency sweep and parameter extraction by using mobile phone

Abstract

The invention discloses a method for utilizing a mobile phone to carry out LTE frequency sweep and parameter extraction. The method comprises the following steps of A.a sub-process step of PLMN selection modification; B.a sub-process step of frequency sweep modification; C.a sub-process step of cell search of the mobile phone; D.a sub-process step of system message parsing the mobile phone; and E.a sub-process step of mobile phone network attachment. The method utilizes a large amount of users to carry out frequency sweep, provides a low-cost and convenient multi-scenario competitive LTE network frequency sweep data acquisition tool for an operator and combines the frequency sweep data with the GPS information to form a frequency sweep log to be sent to a server to carry out statistics, analysis and GIS display.

Description

technical field [0001] The invention relates to a data processing method, in particular to a method for carrying out LTE frequency scanning and parameter extraction by using a mobile phone. Background technique [0002] The signal strength of the wireless network at the geographic location of the mobile communication user has always been a basic indicator that mobile communication operators care about. How to obtain the signal strength of all wireless networks of the operator and other operators in all possible geographical locations of users on a large scale and at low cost has always been the focus of mobile communication operators. [0003] Mobile communication operators generally use the following three schemes to obtain the signal strength of the LTE wireless network: [0004] 1. Obtain the signal strength of the LTE wireless network of the operator and competitors through a professional frequency scanner; [0005] 2. Obtain the signal strength of the LTE wireless net...

AI Technical Summary

Problems solved by technology

[0007] Although mobile communication operators have the above three solutions, obtaining the signal strength of the LTE wireless network requires a lot of manpower and material resources, and the cost is very high. There are certain defects in the existing three solutions:

[0009] 1. The cost of hardware purchase and the manpower and material costs of operation and maintenance are very high, making it difficult to carry out testing work on a large scale;

[0010] 2. An external GPS is required to obtain location information;

[0011] 3. Unable to obtain community information;

[0012] 4. Professional testing equipment is not easy to carry, and it is difficult to carry out testing work in special scenarios such as airport waiting halls

[0014] 1. The cost of hardware purchase and the manpower and material costs of operation and maintenance are very high, making it difficult to carry out testing work on a large scale;
