Embodiment Construction

[0039] This embodiment provides an adaptive coverage optimization method, specifically adopting the following scheme:

[0040] After filtering the measurement information collected according to the measurement messages, location information and time information reported by the terminals in the area to be optimized, select and correct the propagation model, and generate a coverage map according to the corrected propagation model;

[0041] When it is determined that there is a coverage problem according to the coverage map and the measurement information, match the optimization adjustment strategy corresponding to the coverage problem, and send it to the base station for adjustment.

[0042] Further, the optimal adjustment strategy specifically includes: adjusting electronic downtilt and downlink power parameters.

[0043] Further, the measurement message reported by the terminal at least includes: downlink pilot strength measurement, serving cell CGI and other information.

Abstract

The invention discloses a method and device for self-adaptively optimizing coverage. The method comprises the steps of: selecting and correcting a propagation model based on collected measurement information of a terminal and data of a base station within a to-be-optimized region; generating a coverage map based on a corrected propagation model; when a coverage problem exists through the judgment based on the coverage map and the measurement information, matching an optimization adjustment strategy corresponding to the coverage problem, and issuing the optimization adjustment strategy to the base station for coverage optimization adjustment. With the adoption of the method and device for self-adaptively optimizing the coverage, coverage problems can be discovered and optimized automatically, and therefore the quality of the wireless network can be improved efficiently.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an adaptive coverage optimization method and device. Background technique [0002] Traditional wireless network coverage optimization mainly includes five parts: test preparation, data collection, problem analysis, simulation verification, and adjustment and implementation. instrumentation data, as well as eNodeB (base station) side call trace data and configuration data for fault location. [0003] At present, with the fierce competition among operators, operators hope to reduce operating expenses and reduce expenditures for planning, configuration, testing, adjustment, etc.; Too fine-grained (each user, each service, each signaling process), requiring real-time or near-real-time optimization. [0004] Based on this trend, SON (Self Organizing Network, self-organizing network) is proposed, including processes such as self-configuration and self-optimizat...
