Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a positioning method, apparatus, network equipment, terminal equipment and storage medium. Background Art

[0002] The existing fourth generation mobile communication technology (4th Generation Mobile Communication Technology, 4G) terminal equipment positioning usually adopts the global positioning system (Global Positioning System, GPS) combined with 4G base station positioning. Because GPS includes a satellite communication link, the round-trip communication delay is relatively high, which makes the accuracy of the terminal device's location low when the terminal is positioned in real time. In addition, the coverage radius of the 4G base station is about 1-3 kilometers, and the coverage radius is relatively large. Therefore, the existing positioning method can only locate the terminal device within the coverage radius of the 4G base station, so that when the terminal device is positioned using the existing positioning method, the terminal device's location accuracy is low.

[0062] In summary, the method provided by the present disclosure is that the network device can receive the first identification information of the first (Synchronization Signal / PBCH, SSB) signal sent by the terminal device and the second identification information of the second SSB signal, wherein the first SSB signal is the SSB signal of the first base station of the service cell of the terminal device, and the second SSB signal is the SSB signal of the second base station of the adjacent cell of the terminal device; the first deflection angle of the terminal device relative to the first base station is determined according to the first identification information; the second deflection angle of the terminal device relative to the second base station is determined according to the second identification information; the position of the terminal device is determined according to the first deflection angle and the second deflection angle. When the first base station and the second base station are fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) base stations, due to the greater number of 5G base stations, the coverage radius of 5G base stations is much smaller than that of 4G base stations. Therefore, when the terminal device is positioned according to the SSB synchronization broadcast block signal of the 5G base station, the position accuracy of the terminal device can be improved. The accuracy of the position of the terminal device can be determined. Since GPS includes a satellite communication link, the round-trip communication delay is high, so that when the terminal is positioned in real time, the accuracy of the position of the terminal device is low. In addition, since there are more 5G base stations, the coverage radius of 5G base stations is much smaller than that of 4G base stations, and the communication delay between terminal devices and 5G base stations is smaller. Therefore, the terminal devices can be positioned in real time and accurately based on the SSB signals of 5G base stations.

Therefore, the present disclosure may be specifically implemented in the following forms, namely: complete hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0077] In view of the defects in the prior art, this example implementation first provides a positioning method to locate the terminal device through the SSB signal of the 5G base station, thereby avoiding the problem that the accuracy of the terminal device's position and the position precision of the terminal device are low when the prior art is used to perform instant positioning of the terminal. Figure 1 As shown in , the above positioning method may include the following steps:

[0082] In summary, the method provided by the present disclosure is that the network device can receive the first identification information of the first SSB signal and the second identification information of the second SSB signal sent by the terminal device, the first SSB signal is the SSB signal of the first base station of the service cell of the terminal device, and the second SSB signal is the SSB signal of the second base station of the adjacent cell of the terminal device; determine the first deflection angle of the terminal device relative to the first base station according to the first identification information; determine the second deflection angle of the terminal device relative to the second base station according to the second identification information; determine the position of the terminal device according to the first deflection angle and the second deflection angle, when the first base station and the second base station are 5G base stations, due to the greater number of 5G base stations, the coverage radius of 5G base stations is much smaller than that of 4G base stations, so when the terminal device is positioned according to the SSB signal of the 5G base station, the position accuracy of the terminal device can be improved. In addition, due to the greater number of 5G base stations, the coverage radius of 5G base stations is much smaller than that of 4G base stations, and the communication delay between the terminal device and the 5G base station is smaller, the terminal device can be positioned in real time and accurately according to the SSB signal of the 5G base station.

[0083] Below, each step of the positioning method in this example implementation will be described in more detail with reference to the accompanying drawings and embodiments.

[0084] In step S11, first identification information of a first SSB signal and second identification information of a second SSB signal sent by a terminal device are received; the first SSB signal is an SSB signal of a first base station of a service cell of the terminal device, and the second SSB signal is an SSB signal of a second base station of an adjacent cell of the terminal device.

[0085] In an exemplary embodiment of the present disclosure, referring to Figure 2The system architecture shown may include: a terminal device 201, a first base station 202, a second base station 203, and a network device 204. The first base station 202 is a base station of a serving cell of the terminal device 201, and the second base station 203 is a base station of an adjacent cell of the terminal device 201. The terminal device 201 may be connected to the first base station 202 and the second base station 203 for communication; the network device 204 may be a network management device, and the first base station 202 and the second base station 203 may be connected to the network device 204 for communication. The above positioning method may be executed by the terminal device, or may be executed by the terminal device in collaboration with the first base station, or may be executed by the terminal device in collaboration with the network device. Taking the above-mentioned cooperation between the terminal device and the network device as an example, the terminal device receives the third SSB signal sent by the first base station and the fourth SSB signal sent by the second base station, the third SSB signal includes the identification information of the third SSB signal, and the fourth SSB signal includes the identification information of the fourth SSB signal; and determines the first SSB signal from the third SSB signal, and obtains the first identification information of the first SSB signal from the first SSB signal; then determines the second SSB signal from the fourth SSB signal, and obtains the second identification information of the second SSB signal from the second SSB signal; and then sends the first identification information of the first SSB signal and the second identification information of the second SSB signal to the network device. The network device determines the first deflection angle of the terminal device relative to the first base station according to the first identification information and determines the second deflection angle of the terminal device relative to the second base station according to the second identification information; and then determines the position of the terminal device according to the first deflection angle and the second deflection angle.

[0086] In step S12, a first deviation angle of the terminal device relative to the first base station is determined according to the first identification information.

[0087] In an exemplary embodiment of the present disclosure, the first identification information is the first sequence number of the first SSB signal among the multiple SSB signals sent by the first base station. Specifically, the first deflection angle can be calculated according to the following formula:

[0088] a=n1*β (1);

[0089] Wherein, a is the first deflection angle, n1 is the first serial number, β is the beam angle, and the beam angle is the beam angle of the SSB signal, and the beam angle of each SSB signal sent by each 5G base station is consistent. Figure 3 As shown, the first beam angle is the SSB signal 2 sent by the first base station, that is, n1 is 2. When the beam angle is 15°, the first deflection angle is a=2*15°, that is, a=30°.

[0090] In step S13, a second deviation angle of the terminal device relative to the second base station is determined according to the second identification information.

[0091] In an exemplary embodiment of the present disclosure, the second identification information is a second sequence number of the second SSB signal in a plurality of SSB signals sent by the second base station. Specifically, the second deflection angle can be calculated according to the following formula:

[0092] b = n2*β (2);

[0093] Wherein, b is the second deflection angle, and n2 is the second serial number. For example, when n2 is 3 and the beam angle is 15°, the first deflection angle is 2*15°, i.e., 30°. Figure 3 As shown, the second beam angle is the SSB signal 3 sent by the second base station, that is, n2 is 3. When the beam angle is 15°, the first deflection angle is b=3*15°, that is, b=45°. In step S14, the position of the terminal device is determined according to the first deflection angle and the second deflection angle.

[0094] In step S14, the position of the terminal device is determined according to the first deflection angle and the second deflection angle.

[0095] In an exemplary embodiment of the present disclosure, determining the position of the terminal device according to the first deflection angle and the second deflection angle includes:

[0096] S141. Obtain a first height and a first downtilt angle of the first base station;

[0100] S145. Determine the location of the terminal device by calculation according to the first distance and the second distance.

[0101] In an exemplary embodiment of the present disclosure, the first SSB signal also includes identification information of the first base station, and the second SSB signal also includes identification information of the second base station. The network device can obtain the first height and the first downtilt angle from the first base station according to the identification information of the first base station, and obtain the second height and the second downtilt angle from the second base station according to the identification information of the second base station.

[0102] Based on the above content, in an exemplary embodiment of the present disclosure, calculating the first distance between the terminal device and the first base station according to the first deflection angle, the first height, and the first downtilt angle includes:

[0103] S1431, calculating a first angle sum of the first deflection angle and the first downtilt angle, and calculating a first sine value of the first angle sum;

[0104] S1432, calculating a first cosine value of the first downtilt angle, and calculating a first product of the first cosine value and the first height;

[0105] S1433. Calculate a first ratio of the first product to the first sine value, and use the first ratio as the first distance.

[0106] Specifically, combined Figure 3 As shown, the first distance can be calculated using the following formula:

[0107]

[0108] Wherein, x1 represents the first distance, α represents the first downward inclination angle, and h1 represents the first height.

[0109] Based on the above content, in an exemplary embodiment of the present disclosure, calculating the second distance between the terminal device and the second base station according to the second deflection angle, the second height, and the second downtilt angle includes:

[0110] S1441, calculating a second angle sum of the second deflection angle and the second downtilt angle, and calculating a second sine value of the second angle sum;

[0111] S1442, calculating a second cosine value of the second downtilt angle, and calculating a second product of the second cosine value and the second height;

[0112] S1443. Calculate a second ratio of the second product to the second sine value, and use the second ratio as the second distance.

[0113] Specifically, combined Figure 3As shown, the first distance can be calculated using the following formula:

[0114]

[0115] Wherein, x2 represents the second distance, θ represents the second downward inclination angle, and h2 represents the second height.

[0116] In an exemplary embodiment of the present disclosure, the calculating and determining the position of the terminal device according to the first distance and the second distance includes:

[0117] S1451, calculating a third product of the first distance and the first cosine value and calculating a fourth product of the first distance and the sine value of the first deflection angle;

[0118] S1452. Determine a first position of the terminal device relative to the first base station according to the third product and the fourth product;

[0119] S1453, calculating a fifth product of the second distance and the second cosine value and calculating a sixth product of the second distance and the sine value of the second deflection angle;

[0120] S1454. Determine a second position of the terminal device relative to the second base station according to the fifth product and the sixth product;

[0121] S1455. Determine the location of the terminal device according to the first location and the second location.

[0122] Specifically, combined Figure 3 As shown, a coordinate system is established with the horizontal line where the first base station and the second base station are located on the horizontal plane as the horizontal coordinate, the position of the first base station on the horizontal plane as the coordinate origin, and the normal line perpendicular to the horizontal plane at the coordinate origin as the vertical coordinate. The first position of the terminal device relative to the first base station is as follows:

[0123] (x1*cos a,x1*sin a) (5);

[0124] Similarly, the second position of the terminal device relative to the second base station is as follows:

[0125] (x2*cos b,x2*sin b) (6).

[0126] Further, after determining the first position and the second position, the position of the first base station is obtained from the first base station according to the identification information of the first base station, and the third position of the first terminal is determined according to the position of the first base station and the first position; the position of the second base station is obtained from the second base station according to the identification information of the second base station, and the fourth position of the first terminal is determined according to the position of the second base station and the second position, and then the position of the terminal device is determined according to the third position and the fourth position. In an exemplary embodiment of the present disclosure, the average value of the third position and the fourth position can be used as the position of the terminal device.

[0127] It should be noted here that, in an exemplary embodiment of the present disclosure, the network device can also receive second identification information of the second SSB signals of multiple other second base stations sent by the terminal device, and determine the position of the terminal device corresponding to each second identification information based on each second identification information in the second identification information of the second SSB signals of the multiple second base stations and the first identification information, and then determine the position of the terminal device based on the position of the terminal device corresponding to each second identification information (for example, taking the average value of the positions of the terminal devices corresponding to multiple second identification information as the position of the terminal device).

[0128] Specifically, the terminal device measures the first SSB signal with the largest signal strength among the SSB signals sent by the first base station (base station 1) of the service cell, which is SSB signal 2. There are three second base stations in the adjacent cells, namely base station 2, base station 3 and base station 4. The terminal device measures the second SSB signal with the largest signal strength among the SSB signals sent by base station 2, which is SSB signal 1. The terminal device measures the second SSB signal with the largest signal strength among the SSB signals sent by base station 3, which is SSB signal 4. The terminal device measures the second SSB signal with the largest signal strength among the SSB signals sent by base station 4, which is SSB signal 3. The terminal device sends the identification information of base station 1 and the serial number 2 of the first SSB signal to the network device, and sends the identification information of base station 2 and the serial number 1 of the second SSB signal, the identification information of base station 3 and the serial number 4 of the second SSB signal, and the identification information of base station 4 and the serial number 3 of the second SSB signal to the network device respectively. The network device determines the position of the terminal device corresponding to base station 2 based on the identification information of base station 1, the sequence number 2 of the first SSB signal, the identification information of base station 2, and the sequence number 1 of the second SSB signal; determines the position of the terminal device corresponding to base station 3 based on the identification information of base station 1, the sequence number 2 of the first SSB signal, the identification information of base station 3, and the sequence number 4 of the second SSB signal; determines the position of the terminal device corresponding to base station 4 based on the identification information of base station 1, the sequence number 2 of the first SSB signal, the identification information of base station 4, and the sequence number 3 of the second SSB signal. Then, the average value of the position of the terminal device corresponding to base station 2, the position of the terminal device corresponding to base station 3, and the position of the terminal device corresponding to base station 4 is obtained, and the average value is used as the position of the terminal device. The process of determining the position of the terminal device corresponding to base station 2, the position of the terminal device corresponding to base station 3, and the position of the terminal device corresponding to base station 4 can be referred to. Figure 2 The embodiments are not described in detail here.

[0129] In summary, the method provided by the present disclosure, when the first base station and the second base station are 5G base stations, since the number of 5G base stations is greater and the coverage radius of 5G base stations is much smaller than that of 4G base stations, the position accuracy of the terminal device can be improved when the terminal device is positioned according to the SSB signal of the 5G base station. In addition, since the number of 5G base stations is greater and the coverage radius of 5G base stations is much smaller than that of 4G base stations, the communication delay between the terminal device and the 5G base station is smaller, so the terminal device can be positioned in real time and accurately according to the SSB signal of the 5G base station.

[0130] In an exemplary embodiment of the present disclosure, reference Figure 4 As shown, a positioning method is provided, which can be used for a terminal device, and specifically, can include:

[0131] S401, receiving a third SSB signal sent by a first base station of a serving cell and a fourth SSB signal sent by a second base station of a neighboring cell, wherein the third SSB signal includes identification information of the third SSB signal, and the fourth SSB signal includes identification information of the fourth SSB signal;

[0132] S402, determining a first SSB signal from the third SSB signal, and acquiring first identification information of the first SSB signal from the first SSB signal;

[0133] S403, determining a second SSB signal from the fourth SSB signal, and acquiring second identification information of the second SSB signal from the second SSB signal;
