Embodiment

[0048] A wireless network coverage blind spot detection method of the present invention is applied to the LTE network coverage blind spot detection on the campus of Huazhong University of Science and Technology, wherein the signaling data fed back by the user terminal comes from 12 base stations in Huazhong University of Science and Technology, and the relative attenuation value of the user signal Points greater than 95% of the maximum relative attenuation value are considered deep fading points. figure 2 The coverage blind area map on the campus of Huazhong University of Science and Technology provided by the embodiment of the present invention. Among them, the dots represent deep fading points, and the circles represent coverage blind spots. Such as figure 2As shown, a total of 9 coverage holes are found in the coverage area of ​​12 base stations, and the coordinates of the center point of the detected coverage holes and the measured RSRP value are shown in Table 1.

Abstract

The invention discloses a wireless network coverage blind area detection method, which comprises the following steps: determining a user position and a user moving speed according to signaling data fed back by a user terminal; removing user data of fast moving users; calculating a relative attenuation value of a medium-low speed user signal; determining the depth fading point according to the relative attenuation value of the user signal, and determining the suspected coverage blind area according to the distribution of the depth fading point. if the suspected coverage blind area is kept in the deep fading state, determining the suspected coverage blind area as the signal coverage blind area. Compared with the existing method, the method of the invention fully utilizes the existing data ofthe operator, can calculate and obtain more accurate user moving speed so as to effectively eliminate invalid user data, and utilizes the relative attenuation value of the user signal, thereby improving the detection precision of covering the blind area and saving manpower and material resources.

Description

technical field [0001] The invention belongs to the technical field of mobile networks, in particular to a method for detecting wireless network coverage blind spots Background technique [0002] With the development of communication technologies, mobile networks have become very popular. However, for operators, due to limited communication resources, it is impossible for the mobile network to cover all areas, and the areas that cannot be covered by the mobile network can be called blind areas of the mobile network. The existence of these blind spots not only affects the experience of mobile phone users but also affects the economic benefits of operators. Therefore, operators also very much hope to be able to discover blind areas of the mobile network in time, so as to build base stations in this area in time and expand the network coverage of operators. [0003] In the existing technology, the operator can know which areas have blind spots, either through complaints from ...
