detailed description

In the embodiment of the present invention, the MR data of each terminal in the specified area is obtained; the position of each terminal is determined according to the MR data, and the center position of the user cluster composed of the terminals is determined, and each terminal covering the user cluster is determined. A cell cluster composed of cells; adjusting each base station antenna in the cell cluster according to the center position of the user cluster.

The present invention will be described in further detail below in conjunction with the examples.

The antenna adjustment method provided by the embodiment of the present invention, as shown in FIG. 1, the method includes:

Step 101: Obtain MR data of each terminal in a designated area;

Specifically, first specify the area that needs signal adjustment. Here, all network coverage areas can be divided into multiple signal adjustment areas, or some key areas can be manually divided by network optimization personnel based on experience; the signal adjustment area can be Set a threshold for performance parameters such as SINR within the range, and if the performance parameters are found to exceed the threshold range during daily inspections, start adjustment; after determining the area that needs signal adjustment, obtain the MR data of each terminal in the designated area; The MR data includes: the cell number (Ecell_ID) of the primary cell, the cell number (Ecell ID) of the neighboring cell, the International Mobile Subscriber Identification Number (IMSI: International Mobile Subscriber Identification Number), the measurement sampling time, and the received signal field strength of the user terminal ( RSRP, Reference SignalReceiving Power), signal interference signal and SINR at the location of the user terminal, TDOA from the terminal to the active base station, time difference of arrival TDOA from the terminal to the neighboring base station, etc.

The terminal can also be required to report the latitude and longitude of the navigation system where it is located. Here, positioning information can be obtained from the S1-U interface. Some application data includes longitude and latitude positioning information. These terminal applications include: Baidu Maps, Didi Taxi, Kuaidi Taxis, Taobao and other applications. The positioning information may include: global positioning system (GPS, Global Positioning System) positioning information, wireless local area network (WLAN, Wireless Local Area Networks) positioning information.

Step 102: Determine the position of each terminal according to the MR data, and determine the center position of the user cluster formed by the various terminals, and the cell cluster formed by the cells covering the user cluster;

Here, each terminal including the same coverage cell in the MR data is determined as a user cluster; the same coverage cell is determined as a cell cluster; the coverage cell includes: a primary cell and a neighboring cell. For example: in the MR data of user 1 terminal, the main cell is A, and the neighboring cell is B/C/D; The terminal with A/B/C/D cell in the regional MR data is determined as the user cluster, and the A/B/C/D cell is determined as the cell cluster; calculate the direction angle and downtilt angle of the antenna according to the cell cluster and the user cluster; sending and adjusting the electronic azimuth and electronic downtilt according to the azimuth and downtilt;

After the user cluster is determined, due to the high accuracy of the positioning information, the system first determines the location of each user terminal based on the latitude and longitude of the navigation system reported by the user terminal; if the user terminal does not have or does not have the navigation system positioning function, then Determine the distance between the user terminal and the main cell and neighboring cells through the TDOA reported in the MR data;

As shown in Figure 2, the main serving base station and neighboring base stations from the user 1 terminal to the user n terminal are a, b, and c. Here, for the user terminal with accurate positioning information, the precise positioning information is used; for the user terminal positioned by TDOA , the distance between the user terminal and the main cell and neighboring cells determined according to the TDOA can be directly adopted; the longitude and latitude of the base station are imported into the analysis server, and since the position of the base station has been uniquely determined on the map, the distance between each user terminal and the base station can be located by calculating the distance The location of the user terminal; after determining the distance between a terminal and the base station, the average distance between the user cluster and each base station antenna in the cell cluster can be calculated; here, after determining the position of each user terminal, due to the user cluster The user group in the middle is scattered, and it is necessary to determine the center position of the user terminal group in the entire user cluster; the center position can be located by the following methods:

Assume that the distance between user terminals 1, 2, 3...n in the user cluster and base station a can be expressed as: S _a1 , S _a2 ...S _an ; the average distance between user terminals in the user cluster and base station a can be expressed by the expression (1) express:

Similarly, the average distances S _b , S _c ... from user clusters to neighboring base stations b, c ... can be obtained;

As shown in Figure 3, after obtaining the average distance between the user cluster and the base station, the center point O of the user cluster can be located, which can locate the center of the user terminal group under the base station cluster, and the surrounding base stations can cover this point. For optimal coverage.

Step 103: Adjust the base station antennas in the cell cluster according to the center position of the user cluster;

Here, the downtilt angles of the antennas may be determined according to the heights of the base station antennas and the ground distance from the base station antennas to the center of the user cluster, and the base station antennas may be adjusted according to the downtilt angles of the antennas;

The analysis server can obtain the downtilt angle of the main cell of base station a, which can be expressed by expression (2):

Among them, θ _a represents the downtilt angle of the main cell of base station a, and h _a represents the station height of base station a; similarly, the downtilt angle of other adjacent cells can be obtained;

Further, adjusting the base station antennas by using the angle between the connection line between the base station antennas and the center position of the user cluster and the reference direction as the azimuth angle;

In the base station system, the azimuth angle of the cell can be the azimuth angle of the cell with the clockwise rotation of the reference direction, and a coordinate system is established in the electronic map in the analysis server; here, the reference direction can be a true north direction; as shown in Figure 4 ; Through the electronic map coordinate system, it can be obtained that α _a is the main azimuth angle of base station a; similarly, the azimuth angles of other adjacent cells can be obtained, and the analysis server sends the azimuth angles to the electronic azimuth angle of the radio frequency unit of the base station to adjust the antenna.

The antenna adjustment method provided in the embodiment of the present invention further includes:

Gradually depress the inclination angle, obtain each SINR value in the MR data of the user cluster after each depress, and calculate the sum and average of the respective SINR values corresponding to each depress, and determine the maximum of the sum and average of the various SINR values The downtilt angle corresponding to the value; according to the downtilt angle corresponding to the average maximum value of each SINR value, adjust each base station antenna in the cell cluster;

Here, since the main points of the cell and its adjacent cells are all O points, and because the LTE system is a co-frequency multiplexing system, it will inevitably cause strong interference, so the small inclination angle needs to be further adjusted; due to the upward and downward inclination angles, the cell will be over-covered , using the method of gradually pressing down the inclination angle, collecting the MR data of each user terminal during the pressing process, and summing and averaging the SINR values. As shown in Figure 5, during the push-down process, due to the continuous weakening of the field strength RSRP value of the adjacent cell, the sum of the average SINR value becomes better. will get worse. Therefore, the SINR extremum will appear in the process of the cell downtilt. The adjustment unit is adjusted once per second. After each adjustment, the analysis server collects the MR data of the user terminal set, analyzes the average SINR value, and obtains the optimal downtilt angle θ _max . The analysis server sends the optimal downtilt angle to the base station radio frequency. The unit adjusts the electronic downtilt of the antenna.

The antenna adjustment method provided by the embodiment of the present invention further includes: performing the antenna adjustment again according to the change of the position of the user cluster; When the SINR threshold of the user cluster arrives, re-adjust the antenna; re-adjust the antenna regularly;

Due to the tidal effect of the user's actual location, the user is in the workplace during the day and goes home at night, so the cell adjustment device needs to make corresponding adjustments to the user's location change caused by the tidal effect. During the period, adjust the antenna according to the above steps. At the same time, the network optimization personnel can also set the SINR threshold of the user cluster according to the special situation, and adjust it when the SINR value of the user cluster drops to a certain value.

In practical applications, as shown in Figure 6, the background server of the network management of the base station can obtain the MR data reported by the UUS (User to User signal)/S1 port, and calculate the antenna azimuth and downtilt angle according to the MR data; The antenna orientation and downtilt are sent to the base station, and the base station sends a control signal to a remote control unit (RCU, Remote Control Unit) to adjust the antenna; wherein, the positions of the RCU and the antenna can be shown in FIG. 7 .

The positive effects produced by the present invention will be further described in detail below in conjunction with specific examples.

As shown in Figure 8, the specific process of antenna adjustment under the actual working conditions of this example is as follows:

Step 801: Import base station parameters, collect user terminal MR data, and collect user terminal GPS latitude and longitude;

Step 802: Determine whether the SINR of the cell is lower than the threshold according to the MR data of the user terminal; if it is lower than the threshold, execute step 803; otherwise, judge whether it is necessary to perform mandatory antenna adjustment, and if so, proceed to step 803; otherwise, the process ends ;

Step 803: Divide user clusters and cell clusters by reporting MR data, and calculate user cluster center points;

Step 804: Calculate the downtilt angle and azimuth angle from each cell in the cell cluster to the cluster center through the industrial parameters and the center point of the user cluster;

Step 805: adjust the electronic inclination and electronic azimuth of the antenna by lowering the downtilt and azimuth of the transmitting radio unit;

Step 806: Depress the downtilt angle of each cell in the cell cluster in degrees, and judge whether the SINR is rising, until the SINR value is no longer rising, take the downtilt angle corresponding to the highest point of the SINR value to adjust the antenna;

Step 807: The adjustment ends.

Here, all network coverage areas can be divided into multiple signal adjustment areas, or some key areas can be manually divided by network optimization personnel based on experience; the signal adjustment area can be Set a threshold for performance parameters such as SINR within the range, and if the performance parameters are found to exceed the threshold range during daily inspections, start adjustment; after determining the area that needs signal adjustment, obtain the MR data of each terminal in the designated area; MR data includes: the cell number Ecell_ID of the main cell, the cell number Ecell ID of the neighboring cell, IMSI, measurement sampling time, RSRP of the user terminal, signal interference signal and SINR at the location of the user terminal, TDOA from the terminal to the main base station , the time difference of arrival TDOA between the terminal and the base station in the neighboring cell, etc. The terminal can also be required to report the latitude and longitude of the navigation system where it is located. Here, positioning information can be obtained from the S1-U interface. Some application data includes longitude and latitude positioning information. These terminal applications include: Baidu Maps, Didi Taxi, Kuaidi Taxis, Taobao and other applications. The positioning information may include: GPS positioning information, WLAN positioning information.

The determination module 92 is configured to determine the position of each terminal according to the MR data, and determine the center position of the user cluster composed of the terminals, and the cell cluster formed by the cells covering the user cluster;

Specifically, each terminal including the same coverage cell in the MR data is determined as a user cluster; the same coverage cell is determined as a cell cluster; the coverage cell includes: a primary cell and a neighboring cell. For example: in the MR data of user 1 terminal, the main cell is A, and the neighboring cell is B/C/D; The terminal with A/B/C/D cell in the regional MR data is determined as the user cluster, and the A/B/C/D cell is determined as the cell cluster; calculate the direction angle and downtilt angle of the antenna according to the cell cluster and the user cluster; sending and adjusting the electronic azimuth and electronic downtilt according to the azimuth and downtilt;

After the user cluster is determined, due to the high accuracy of the positioning information, the system first determines the location of each user terminal based on the latitude and longitude of the navigation system reported by the user terminal; if the user terminal does not have or does not have the navigation system positioning function, then Determine the distance between the user terminal and the main cell and neighboring cells through the TDOA reported in the MR data;

As shown in Figure 2, the main serving base station and neighboring base stations from the user 1 terminal to the user n terminal are a, b, and c. Here, for the user terminal with accurate positioning information, the precise positioning information is used; for the user terminal positioned by TDOA , the distance between the user terminal and the main cell and neighboring cells determined according to the TDOA can be directly used; the longitude and latitude of the base station are imported into the analysis server, since the position of the base station has been uniquely determined on the map, the distance between each user terminal and the base station can be located by calculating the distance The location of the user terminal; after determining the distance between a terminal and the base station, the average distance between the user cluster and each base station antenna in the cell cluster can be calculated; here, after determining the position of each user terminal, due to the user cluster The user group in the middle is scattered, and it is necessary to determine the center position of the user terminal group in the entire user cluster; the center position can be located by the following methods:

Assume that the distance between user terminals 1, 2, 3...n in the user cluster and base station a can be expressed as: S _a1 , S _a2 ...S _an ; the average distance between user terminals in the user cluster and base station a can be expressed by the expression (1) express;

Similarly, the average distances S _b , S _c ... from user clusters to neighboring base stations b, c ... can be obtained;

As shown in Figure 3, after obtaining the average distance between the user cluster and the base station, the center point O of the user cluster can be located, which can locate the center of the user terminal group under the base station cluster, and the surrounding base stations can cover this point. For optimal coverage.

The control module 93 is configured to adjust each base station antenna in the cell cluster according to the center position of the user cluster.

Specifically, the downtilt angle of the antenna may be determined according to the height of each base station antenna and the ground distance from each base station antenna to the center of the user cluster, and the base station antennas may be adjusted according to the downtilt angle of the antenna;

The analysis server can obtain the downtilt angle of the main cell of base station a, which can be expressed by expression (2); among them, θ _a represents the downtilt angle of the main cell of base station a, and h _a represents the station height of base station a; similarly, the downtilt angle of other adjacent cells can be obtained. inclination;

Further, adjusting the base station antennas by using the angle between the connection line between the base station antennas and the center position of the user cluster and the reference direction as the azimuth angle;

In the base station system, the azimuth angle of the cell can be the azimuth angle of the cell with the clockwise rotation of the reference direction, and a coordinate system is established in the electronic map in the analysis server; here, the reference direction can be a true north direction; as shown in Figure 4 ; Through the electronic map coordinate system, it can be obtained that α _a is the main azimuth angle of base station a; similarly, the azimuth angles of other adjacent cells can be obtained, and the analysis server sends the azimuth angles to the electronic azimuth angle of the radio frequency unit of the base station to adjust the antenna.

The antenna adjustment device provided by the embodiment of the present invention, the control module 93 is also used for:

Gradually depress the inclination angle, obtain each SINR value in the MR data of the user cluster after each depress, and calculate the sum and average of the respective SINR values corresponding to each depress, and determine the maximum of the sum and average of the various SINR values The downtilt angle corresponding to the value; according to the downtilt angle corresponding to the average maximum value of each SINR value, adjust each base station antenna in the cell cluster;

Here, because the main points of the cell and its adjacent cells are all O points, and because the LTE system is a same-frequency multiplexing system, it will inevitably cause strong interference, so the small inclination angle needs to be further adjusted. Since raising the downtilt angle will cause over-coverage of the cell, the way of gradually lowering the downtilt angle is adopted, and the MR data of each user terminal are collected during the depressing process, and the SINR values are summed and averaged. As shown in Figure 5, during the push-down process, the SINR value becomes better due to the continuous weakening of the field strength RSRP value of the adjacent cell, but with further push-down, the SINR of the user terminal will become worse because the cell coverage is out of the area of each user terminal. Therefore, the SINR extremum will appear in the process of the cell downtilt. The adjustment unit is adjusted once per second. After each adjustment, the analysis server collects the MR data of the user terminal set, analyzes the average SINR value, and obtains the optimal downtilt angle θ _max . The analysis server sends the optimal downtilt angle to the base station radio frequency. The unit adjusts the electronic downtilt of the antenna.

Due to the tidal effect of the user's actual location, the user is in the workplace during the day and goes home at night, so the cell adjustment device needs to make corresponding adjustments to the user's location change caused by the tidal effect. During the period, adjust the antenna according to the above steps. At the same time, the network optimization personnel can also set the SINR threshold of the user cluster according to the special situation, and adjust it when the SINR value of the user cluster drops to a certain value.

In practical applications, as shown in Figure 6, the background server of the base station network management can obtain the MR data reported at the UUS/S1 port, and calculate the antenna azimuth and downtilt according to the MR data; send the antenna azimuth and downtilt to the base station, and the The base station sends a control signal to the RCU to adjust the antenna; wherein, the positions of the RCU and the antenna may be as shown in FIG. 7 .
