Embodiment Construction

[0101] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0102] image 3 The flowchart of a preferred embodiment of the plane fitting-based wireless positioning measurement method of the present invention is shown. See image 3 , a detailed description of each step in the method follows.

[0103] Step S100: Store the ground plane positions (x i ,y i ,z i ) and the corresponding base station antenna height h i , where i is the base station number, the location of the ground plane and the corresponding base station antenna height are known information, provided by network planning and operators.

[0104] Step S101: Determine whether the terminal side performs position estimation, that is, whether it is a terminal-led mode. If yes, go to step S102, otherwise go directly to step S103.

[0105] Step S102: The RNC transmits relevant base station information to the terminal through a broadcast channel or a d...

Abstract

The invention discloses a method and a device for wireless positioning measurement based on plane fitting, which can obtain a wireless positioning measurement result under the condition of only two base stations. The technical proposal of the invention comprises the steps that: the method calculates the transmission time delay of downlink signals of various base stations according to measurement results of various measurable cell downlink signals by a terminal based on a basic principle of network planning, then utilizes the positions of ground levels of the base stations to fit curved surfaces of the ground levels where the base stations exist, and finally calculates the position of the terminal according to an optimization cost function. The method and the device are applied in the field of mobile communication.

Description

technical field [0001] The invention relates to a wireless positioning measurement method and device, in particular to a plane fitting-based wireless positioning measurement method and device. Background technique [0002] With the development of wireless communication technology, especially after the United States proposed emergency location service requirements, wireless positioning services have attracted more and more attention from the industry. [0003] According to whether mobile phones are required to participate, the collected positioning technologies are mainly divided into two types: mobile positioning technologies that require mobile phones to report information and mobile phone positioning technologies that do not require mobile phones to report information. [0004] For the former, the network system needs to notify the mobile phone through signaling, and the specific location of the mobile phone can be determined only after the mobile phone actively reports re...
