Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The S1 interface is the only communication interface between E-UTRAN (Evolved Terrestrial Radio Access Network) and EPC (4G Core Network). The S1 interface consists of two planes: the control plane S1-MME and the user plane S1-U, E - The access point of UTRAN is eNodeB (base station), and the access point of EPC is MME (Mobility Management Entity) and SGW (Servin...

Abstract

The embodiment of the invention provides a network coverage assessment method and device. The method comprises the following steps: acquiring sample information from a first XDR file at a S1-U interface, wherein the sample information comprises IMSI data of a user terminal, start time of performing location by the user terminal, end time for performing the location by the user terminal, and the longitude and latitude data of the user terminal in the start time and the end time; acquiring the business identifier data corresponding to the IMSI data in start time and the end time; acquiring the signal intensity data corresponding to the service identifier data in the start time and the end time from the MRO file; and determining the network coverage state of the to-be-assessed area according to the longitude and latitude data and the signal intensity data. By using the method provided by the embodiment of the invention, the real situation of the network can be fast, effectively and accurately assessed by using the big data.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for evaluating network coverage. Background technique [0002] In the traditional wireless network optimization test scheme, DT (Drive test) and CQT (Call Quality Test) are the most typical test methods. DT refers to the use of drive test equipment combined with geographical information to conduct comprehensive measurements on the air interface to verify the parameters of the wireless interface, analyze, optimize, and locate faults. CQT refers to testing wireless data network performance at a fixed location. This test method is also commonly used, that is, the terminal is used to dial in some places, and the calling party and the called party each account for a certain proportion. Finally, statistical analysis is performed on the test results to complete the subjective evaluation, so as to have an intuitive understanding of...
