Embodiment 1

[0047] In the above step S301, after determining the location of the base station, relative to the location of the base station, determine a plurality of location ranges whose distance from the location of the base station satisfies the set distance condition. In this embodiment 1, a method based only on the base station is proposed A method for determining the multiple location ranges relative to the base station.

[0048] To determine the distance from the base station location [L i , L i+1 ]’s n position ranges as an example, where i takes integers in [1, n] respectively, and [L i , L i+1 ] corresponds to the i-th position range, L 1 equal to 0, n is an integer greater than 1, that is, among the determined n position ranges, the first position range is based on the base station's position as the center of the circle and L 1 is a circular area with a radius, and the remaining n-1 position ranges are respectively centered on the base station and L i and L i+1 is the ran...

Embodiment 2

[0061] In the above-mentioned embodiment 1, when determining multiple location ranges relative to the base station, only the location of the base station is based. The location of the base station, and the distribution of sampling points between the cell covered by the base station and each adjacent cell, and the method of determining the multiple location ranges relative to the base station.

[0062] To determine the distance from the base station location [L i , L i+1 ]’s n position ranges as an example, where i takes integers in [1, n] respectively, and [L i , L i+1 ] corresponds to the i-th position range, L 1 equal to 0, n is an integer greater than 1, that is, among the determined n position ranges, the first position range is based on the base station's position as the center of the circle and L 1 is a circular area with a radius, and the remaining n-1 position ranges are respectively centered on the base station and L i and L i+1 is the range of the circular area...

Embodiment 3

[0101] [L i , L i+1 ], and the signal strength of the sampling terminal at each sampling point corresponding to the base station determined in the above step S302, the corresponding relationship between multiple signal strength ranges and multiple location ranges can be established. Embodiment 3 In , the method for establishing the corresponding relationship is described in detail.

[0102] When establishing the corresponding relationship, based on the principle that the farther away from the base station the signal strength of the mobile terminal is, the smaller the signal strength range is determined to be [V i+1 , V i ], wherein, since the first location range is the closest to the base station, the signal strength range corresponding to the first location range [V 2 , V 1 ] in V 1 is infinite, since the nth location range is the farthest from the base station, so determine the signal strength range corresponding to the nth location range [V n+1 , V n ] in V n+1 is ...

Abstract

The invention discloses a method and a device for determining position range of a mobile terminal. The method comprises the following steps of: determining a plurality of position ranges from which the distance to the position of a base station meets a preset distance condition; determining the signal intensity of a sampling terminal at each sampling point of the corresponding base station; based on the determined signal intensity of each sampling point and the plurality of position ranges, building a corresponding relation between a plurality of signal intensity ranges and the plurality of position ranges; and based on the built corresponding relation, determining the position range corresponding to the signal intensity range of the current signal intensity of a to-be-positioned mobile terminal as the position range of the to-be-positioned mobile terminal of a home base station. With the scheme provided by the embodiment of the invention, the accuracy of positioning the position range of the mobile terminal based on the position of the base station is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminal positioning in the technical field of wireless communication, in particular to a method and device for determining the location range of a mobile terminal. Background technique [0002] In the location service of the current wireless communication network, there is a solution to locate the location of the mobile terminal according to the location of the base station, that is, to query the Cell-ID of the preset base station according to the cell identification code Cell-ID of the base station of the current serving cell of the mobile terminal to be located The corresponding relationship with the base station position determines the position of the base station of the serving cell, and uses the determined position of the base station as the positioning result of the mobile terminal to be located. This positioning technology is also called base station positioning technology. This tech...
