Abstract

The invention provides a wireless network cross-boundary coverage detection method and device and a communication system. The detection method comprises the steps of acquiring location information and signal information of each measurement report (MR) sampling point in a cell; calculating cross-boundary coverage parameters of the cell according to the location information and the signal information of each measurement report MR sampling point, wherein the cross-boundary coverage parameters comprise whether the cell is a cross-boundary coverage cell or not and a boundary-crossed coverage cell covered by the cell if the cell is a cross-boundary coverage cell. According to implementation of the method, firstly the location information and the signal information of all the MR sampling point in the cell to be detected are acquired, and the cross-boundary parameters of the cell are calculated according to the information. The method has nothing to do with a mobile station, thereby avoiding interference brought about by the mobile station, and being high in accuracy. Furthermore, the method needs to calculate according to multiple parameters, so that the accuracy is further improved, and a problem that an existing cross-boundary coverage judgment method is low in accuracy is solved.

Description

technical field [0001] The invention relates to the field of over-area coverage detection and optimization of a communication system, in particular to a wireless network over-area coverage detection method, device and communication system. Background technique [0002] With the development of wireless networks, mobile operators are vigorously developing LTE wireless networks in order to improve user data service perception. Good wireless coverage is the prerequisite for ensuring the quality and indicators of mobile communication networks. Only by combining reasonable parameter settings can a high-performance wireless network be obtained. The internet. [0003] LTE networks generally use co-frequency networking, and co-frequency interference is serious. Good coverage and interference control are of great significance to network performance. The coverage problems involved are mainly manifested in four aspects: coverage holes, weak coverage, cross-area coverage and pilot pollu...
