A network quality assessment method and device

Abstract

The invention discloses a network quality evaluation method and a network quality evaluation device. The method comprises the following steps: acquiring MRs (Measure Report) reported by a terminal under a first communication system, and determining the MRs belonging to a to-be-evaluated area from the MRs; determining N neighbor cells of a serving cell according to the determined MRs belonging to the same serving cell; determining the coverage coefficient of each neighbor cell according to the signal strength of the neighbor cells in the MRs belonging to the serving cell and the signal strength of the serving cell; and determining first cell overlap coverage meeting the coverage requirement of a second communication mode according to the coverage coefficients of the N neighbor cells, adding up M first cell overlap coverage correspond to different values to get second cell overlap coverage, and determining the overlap coverage of the to-be-evaluated area under the second communication system according to the second cell overlap coverage corresponding to each serving cell in the to-be-evaluated area and the total number of cells in the to-be-evaluated area. Thus, the problem that the result of network quality evaluation based on a simulation model is inaccurate in the prior art is solved.

Description

technical field

[0001] The invention relates to the communication field, in particular to a network quality evaluation method and device. Background technique

[0002] With the development of mobile communication networks, using existing GSM (Global System for Mobile, Global System for Mobile Communications) network sites and spectrum resources to construct LTE-FDD (Time Division Duplex Long Term Evolution) networks has become the main development trend of network evolution. As the number of users continues to increase, the business volume continues to increase, resulting in a continuous aggravation of the network load. Therefore, new base stations are continuously deployed to reduce the load on the network. However, the deployment of new base stations will lead to an increase in the density of base stations. The distance between cells is reduced, leading to an increase in overlapping coverage between cells, which will cause signal interference and affect network quality. I...
