Embodiment Construction

[0030] In the embodiment of the present invention, by analyzing the 3a measurement report sent by the terminal to the base station in the 2-3G handover TOP cell, the received power of each neighboring cell measured by the terminal before the handover is obtained, and the distance between the terminal and the corresponding base station is calculated in combination with the three-dimensional map and the propagation model. starting from the antenna direction angle of the base station, within the set angle range, calculate the received power of the terminal along each angle direction and at the distance between the base station and the terminal according to the angle step value, and calculate from Find the power that best matches the analyzed received power from the received power of the terminal, and use this as a basis to locate the position coordinates of the terminal, so as to obtain the detection result of weak network coverage, and display the weak coverage detection result of...

Abstract

The invention discloses a method and a device for automatically detecting network weak coverage. The method comprise the steps that a survey report reported by a terminal to a base station is obtained, and received power of the terminal is analyzed from the survey report; the distance between the terminal and the corresponding base station is calculated according to the analyzed received powder of the terminal; the terminal received power on the distance between the base station and the terminal in an angle direction is calculated according to a preset angle step value within a set angle range by using a direction angle direction of an antenna of the base station as a start; and position coordinates of the terminal are located according to the calculated terminal received power and the received power analyzed from the survey report; and a network weak coverage detection result is obtained and output according to the position coordinates of the terminal.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for automatic detection of weak network coverage. Background technique [0002] After the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) network construction is completed, due to the difference between the actual situation and the plan, the change of the site and other factors, the network will have weak coverage. Weak coverage refers to the situation where the signal in the boundary area is weak due to the large coverage area required by the base station, the distance between the base stations is too large, or the building is blocked. Usually, when the received power of the terminal is less than -90dBm, it is considered to be weak coverage, such as figure 1 shown. Weak coverage areas not only affect the quality of network calls, but also easily cause call drop, resulting in a series of problems such as low paging response rate. Th...
