Embodiments of the invention disclose an indoor positioning method and apparatus. The method includes: acquiring current cell signal strength information of a terminal located indoors; determining, according to three-dimensional (3D) indoor positioning matching information, horizontal position information and height information of an indoor grid that are corresponding to the current cell signal strength information, where the 3D indoor positioning matching information includes a correspondence between cell signal strength information of the indoor grid and the horizontal position information and the height information of the indoor grid; and determining, according to the horizontal position information and the height information of the indoor grid, a horizontal position at which the terminal is located indoors and a height at which the terminal is located. In this way, high-accuracy 3D indoor positioning can be implemented.

The present invention relates to a method and an apparatus for diagnosing a feeder misconnection. The method includes: for each planned non-co-site strong neighboring cell of a sector to be analyzed, by using each sector of a base station where the sector to be analyzed is located as an interference source, determining a sector having the greatest interference with the non-co-site strong neighboring cell; and when in the planned non-co-site strong neighboring cells of the sector to be analyzed, the sector having the greatest interference with the non-co-site strong neighboring cell is in another sector except the sector to be analyzed, and a ratio of the number of non-co-site strong neighboring cells of the another sector to the total number of the non-co-site strong neighboring cells reaches a preset first threshold, determining that a feeder of the sector to be analyzed is misconnected.
