Problems solved by technology

In a non-cooperative positioning system, even if the location information of the target base station is also obtained and the TA value of the target terminal is obtained, the third-party direction finding equipment cannot easily know the AoA of the target terminal's uplink signal reaching the target base station, that is, under the same conditions, The non-cooperative positioning system can only determine that the target terminal is located on a certain circle centered on the target base station
To make matters worse, in the actual positioning process, due to the difficulty in obtaining the location information of the base station of the newly built network, or other factors, the lack of location information of the target base station is even more unfavorable for third-party direction-finding equipment to carry out the work of locating the target terminal

Embodiment 1

[0076] In general, such as figure 1 As shown, the locations of the target base station 101 and the target terminal 103 are unknown. In this embodiment, the steps of using the third-party direction-finding device 102 to locate the target base station 101 and the target terminal 103 are as follows:

[0077] Step 101: The third-party direction-finding device 102 acquires the timing t when the downlink signal of the target base station 101 arrives at the direction-finding device 102 0 ;

[0078] Step 102: The third-party direction-finding device 102 determines that the AoA (Arrival Angle) value of the downlink signal of the target base station 101 arriving at the direction-finding device 102 is ∠NBA, where the AoA value is defined as taking the direction-finding device 102 as the vertex and the geographical north 104 Rotate clockwise to the target base station 101 in the direction of zero degrees;

[0079] Step 103: The third-party direction-finding device 102 obtains the dista...

Embodiment 2

[0105] Such as image 3 As shown, the purpose of this embodiment is to use the auxiliary terminal 303 and the third-party direction-finding device 302 to locate the target base station 301, and the third-party direction-finding device 302 is required to have the ability to measure the AoA 305 of the downlink signal of the target base station 301, and the auxiliary terminal 303 is required to be capable of obtaining The ability to position itself and send this position information to the direction finding device 302 resolver. The specific positioning method is as follows:

[0106] Step 201: The third-party direction-finding device 302 acquires the timing t when the downlink signal of the target base station 301 arrives at the direction-finding device 302 0 ;

[0107] Step 202: The third-party direction-finding device 302 measures the AoA 305 of the downlink signal of the target base station 301 arriving at the direction-finding device 302;

[0108] Step 203: The third-party ...

Embodiment 3

[0117] Such as Figure 4 As shown, the purpose of this embodiment is to use the auxiliary terminal 403 and the third-party direction-finding device 402 to locate the target base station 401, wherein the third-party direction-finding device 402 does not have the ability to measure the AoA of the downlink signal of the target base station. The specific positioning method is as follows:

[0118] Step 301: The third-party direction-finding device 402 obtains the timing t when the downlink signal of the target base station 401 arrives at the direction-finding device 402 0 ;

[0119] Step 302: The third-party direction-finding device 402 obtains the distance b between the auxiliary terminal 403 and the target base station 401, which is generally calculated by multiplying the time corresponding to the obtained TA value by the speed of light;

[0120] Step 303: The third-party direction-finding device 402 acquires the timing t when the uplink signal of the auxiliary terminal 403 arr...

Abstract

The invention discloses a method for positioning a base station and a terminal. Aiming at a non-cooperative positioning system, third-party direction finding equipment is adopted in the method; by acquiring angle information, distance information, time information and the like of a target base station and a target terminal, possible positions of the target base station and the target terminal are calculated so as to implement positioning; and the adverse effect generated when the target terminal is positioned in a case that the position of the target base station is unknown is overcome. Meanwhile, in a case that position information of an auxiliary terminal exists, the third-party direction finding equipment can position the target base station or give the possible position of the target base station. In a case that position information of the target base station exists, the third-party direction finding equipment can also position the target terminal or give the possible position of the target terminal. The method disclosed by the invention is accurate in positioning and high in efficiency and has very high practical value.

Description

technical field [0001] The invention relates to the field of base station and terminal positioning, in particular to a method for base station and terminal positioning in the field of mobile communication. Background technique [0002] In recent years, non-cooperative positioning has achieved rapid development in the fields of national defense, security, and technical investigation, and has made great contributions to ensuring national security and fighting crime. Among them, in the non-cooperative positioning system, the use of mobile communication signals is an important branch. [0003] The non-cooperative positioning system in the mobile communication system cannot directly obtain the parameters of the target base station or target terminal in the mobile communication cellular network, and needs to monitor the network to intercept the communication timing, signal power and other parameters of the target terminal. Therefore, compared to the commonly used network-based or...
