Coverage evaluation method and device for LTE network

Abstract

The invention provides a coverage evaluation method and device for an LTE network, and relates to the technical field of mobile communication, wherein the method comprises the steps of: obtaining first XDR data used for evaluating coverage of the LTE network from an S1-U interface of the LTE network; according to the switching information and occupation cell information of each user device, obtaining an application scene, which each user device belongs to, by identification; according to the application scene, which each user device belongs to, obtaining the current position of each user device used for being identified on a map; obtaining second XDR data used for evaluating coverage of the LTE network from a Uu interface of the LTE network; according to the basic information of each userdevice, associating the first XDR data with the second XDR data, so that the reference signal receiving power of each user device at the current position is obtained; and, according to the reference signal receiving power of each user device at the current position on the map, evaluating coverage information of the LTE network. By means of the coverage evaluation method and device for the LTE network provided by the invention, the problem that the network coverage cannot be completely reflected in the prior art can be avoided; and furthermore, the problem that the positioning precision is relatively low can be solved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular, to a coverage evaluation method and device for an LTE network. Background technique [0002] At present, there are two main methods for evaluating LTE network coverage, one is the LTE network coverage evaluation method based on DT (Drive Test) / CQT (Call Quality Test), and the other is based on MR (Measurement Report, measurement report) positioning LTE network coverage evaluation method. [0003] 1. LTE network coverage evaluation method based on DT / CQT [0004] DT is a method of measuring wireless network performance by using test equipment to move along a specified route. Different types of calls can be made, test data can be recorded, and network test indicators can be counted. [0005] CQT also refers to testing wireless data network performance at a fixed location. For example, fixed-point tests for government agencies, large hotels, schools, hospitals,...
