Embodiment 1

[0051] When the terminal satisfies the conditions (2), (4), (5) and (7), the positioning process 1 is used to locate the terminal, taking 6 neighboring cells as an example, the positioning process 1 includes the following steps, wherein, in the first embodiment The adjacent cell referred to refers to the non-microcell adjacent cell. For the adjacent cell of the microcell, its data will not be processed. The auxiliary positioning base station in the first embodiment includes the base station to which the serving cell belongs and the base station to which each neighboring cell belongs:

[0052] (1) According to the path loss difference between the terminal and each auxiliary positioning base station, determine the preliminary estimated position of the terminal when the antennas of the base station belonging to the serving cell and the base stations belonging to each neighboring cell are omnidirectional antennas.

[0053] Assume that the antennas of the base station of the serving...

Embodiment 2

[0118] When the terminal satisfies the conditions (2), (4), (5) and (8), the positioning process 2 is used to locate the terminal. Taking 6 neighboring cells as an example, a base station containing more than two cells is called a multi-cell base station. The positioning process 2 includes the following steps, wherein the adjacent cell referred to in the second embodiment refers to a non-microcell adjacent cell, and the data of the adjacent cell of the micro cell is not processed, and the auxiliary positioning base station in the second embodiment includes the serving cell The base station to which it belongs and the base stations to which each neighboring cell belongs:

[0119] (1) Determine the location where the terminal is connected to the multi-cell base station.

[0120] The determination method is as follows: assuming that the angles between the terminal and cell 1 and cell 2 in the multi-cell base station are α and β respectively, then α and β can be determined accordi...

Embodiment 3

[0133] When the terminal satisfies the conditions (2), (4), (5) and (9), the positioning process 3 is used to locate the terminal. Taking 6 neighboring cells as an example, a base station containing more than two cells is called a multi-cell base station. This embodiment three includes two multi-cell base stations: the first multi-cell base station and the second multi-cell base station, and the positioning process 3 includes the following steps, wherein, the adjacent cell referred to in this embodiment three refers to a non-microcell adjacent cell, for The data of the adjacent cells of the microcell will not be processed, and the auxiliary positioning base station in the third embodiment includes the base station to which the serving cell belongs and the base stations to which each neighboring cell belongs:

[0134] (1) Determine a first connection location between the terminal and the first multi-cell base station, and determine a second connection location between the termin...

Abstract

The invention discloses a method, a device and a wireless operation maintenance center for positioning a terminal, which are used for solving the problem that the prior hardware equipment needs to be greatly changed and has low positioning precision in the prior terminal positioning technology. The method comprises the following steps of: determining a preliminary estimation position of the terminal when all the antennas of a service cell subordinate base station and each adjacent cell subordinate base station are omnidirectional antennas according to path loss difference between the terminal and each auxiliary positioning base station, and a standard transmission model; modifying the path loss difference between the terminal and each auxiliary positioning base station according to antenna lobe attenuation on the terminal preliminary estimation position of each auxiliary positioning base station, and determining an adjustment estimation position of the terminal according to the modified path loss difference; and determining the position of the terminal according to the adjustment estimation position of the terminal. The technical scheme avoids modification to the prior equipment and improves the positioning accuracy.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a technology for locating a terminal in GSM (Global System for Mobile communication, Global System for Mobile Communication). Background technique [0002] The terminal positioning service is an important service in the wireless cellular communication system. The existing terminal positioning technologies mainly include the following types: TOA / TDOA (Time of Arrive / Time Difference Of Arrive, time of arrival / time difference of arrival), single base station intelligent Antenna positioning, A-GPS (Assisted Global Positioning System, assisted global positioning system) and field strength positioning, etc. [0003] Among them, the basic working principle of the TOA / TDOA positioning method is: the terminal observes the arrival time difference of at least 3 cell broadcast channels, and feeds back the time difference to the network side, and the network side uses the hyperbolo...
