Embodiment Construction

[0048] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0049] figure 1 A schematic flowchart of a method for calculating indoor signal propagation loss based on a measurement report provided in this embodiment is shown, including:

[0050] S101. Perform grid formation on indoor and outdoor three-dimensional signal coverage areas to obtain a grid set.

[0051] Wherein, the set of grids is a set of individual grids within the three-dimensional signal coverage area.

[0052] Specifically, such as figure 2 As shown, when the signal of the cell antenna reaches the indoor of the building, there will be propagation loss of the indoor signal. According to the floor height (λ) of the building, the indoor area is divided into ...

Abstract

The embodiment of the invention discloses a method and device for calculating indoor signal propagation losses based on a measurement report. The method comprises: rasterization is carried out on indoor and outdoor three-dimensional signal coverage areas to obtain a grid set; according to first propagation losses of all indoor grids in the grid set and corresponding target outdoor grids as well assecond propagation losses from a cell antenna to the target outdoor grids, third propagation losses from the cell antenna to all indoor grids are calculated; and according to signal levels of all indoor grids in a measuring report, the third propagation losses are corrected to obtain target propagation losses from the cell antenna to all indoor grids are obtained. Therefore, indoor model correction is carried out based on measuring report data; the operation becomes convenient and quick; and the time and effort are saved. Meanwhile, the indoor signal propagation loss model is corrected basedon massive user measuring report data; the method and device are implemented for a real client distribution area based on an actual indoor propagation environment; consideration of the specific indoorbuilding structure is not needed; and the accurate indoor coverage planning need is satisfied. The method and device for calculating indoor signal propagation losses are easy to prompt and apply.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication technologies, and in particular to a method and device for calculating indoor signal propagation loss based on measurement reports. Background technique [0002] With the rapid development of 4G mobile communication, the network scale is expanding day by day. In dense urban areas, with the steady progress of large-scale outdoor base station expansion and construction, the outdoor road test indicators in urban areas are good, and wide-area coverage is basically completed. At the same time, users have higher and higher requirements for network quality and deep coverage, and the problem of indoor coverage has become increasingly prominent. In indoor scenes, due to the differences in wall materials, structures, and layouts of buildings, signal propagation is bound to be affected by many factors. Indoor propagation loss models vary greatly, which affects the accuracy of ind...
