As the 4th generation mobile phone mobile communication standard (English full name: the 4th Generation mobile communication technology, English abbreviation: 4G) network is gradually put into commercial use, the scale of 4G users is also increasing rapidly. However, in the initial stage of 4G network establishment, 4G signals are often interfered by other signals, or due to business models, terminal configurations being adjusted, etc., the user experience of 4G users is affected, resulting in a large number of 4G user complaints. How to deal with complaints from 4G users in a timely manner and maintain a stable user base has become an urgent problem to be solved.

With the construction of 4G network, although the wide coverage of 4G network basically meets the market demand, there are still big problems in deep coverage, which may lead to poor wireless network coverage in some areas, and the current 4G user complaints have more than More than half of the complaints are caused by poor wireless network coverage in the area where the complaining user is located. Since the resources needed to comprehensively solve the problem of deep coverage of 4G networks are far beyond the tolerance of each operator, it is necessary to locate the cause of poor wireless network coverage in the area where the complaining user is located, so as to solve it in a targeted manner. Scenarios where deep coverage problems exist in the current 4G network mainly include: urban villages, large communities where stations cannot be built inside, and high-rise residences. Poor wireless network coverage in the above scenarios is usually caused by a problem with the setting of the sector covering the area.

As shown in FIG. 1 , the embodiment of the present invention provides a wireless communication scenario, including a fault complaint point 101 and a base station 102, where one or more sectors are set on the base station 102 . When there is a problem with the setting of the sector for covering the fault complaint point 101 on the corresponding base station 102, it will cause the wireless network coverage of the user located at the fault complaint point 101 to be affected, that is, the user located at the fault complaint point 101 complains. The odds are high.

In order to solve the problem of poor wireless network coverage in the above scenario, it is necessary to evaluate the impact of the sector in the above scenario on the wireless network coverage of the complaining user's location, that is, to determine the sector that needs to be adjusted or optimized, so as to facilitate the sector. Adjust or optimize accordingly.

For the appeal problem, as shown in Figure 2, an embodiment of the present invention provides a sector evaluation method, including:

201. Acquire the coordinates of the fault complaint point, the coordinates of the evaluation base station, and the azimuth of the evaluation sector.

Wherein, the evaluation base station is the base station where the evaluation sector is located, and the evaluation sector is the sector evaluated according to the sector evaluation method provided in the embodiment of the present invention. Since the evaluation sector is on the evaluation base station, the coordinates of the evaluation base station can be considered as The coordinates of the evaluation sector.

Specifically, the coordinates of the fault complaint point can be the coordinates of the complaining user, and the complaining user is the user who generates or reports complaint data, and the location of the user who generates or reports the number of complaints can be obtained according to the coordinates of the fault complaint point. The coordinates of the evaluation base station may be the coordinates of the base station where the evaluation sector is located, and the location of the base station where the evaluation sector is located can be determined according to the coordinates of the evaluation base station. It should be noted that there may be only one evaluation sector on the evaluation base station, or there may be multiple evaluation sectors. Preferably, each evaluation base station is provided with three evaluation sectors.

The azimuth angle of the evaluation sector is used to indicate the emission direction of the evaluation sector, wherein the emission direction of the evaluation sector is the central direction of the coverage area of the evaluation sector.

Specifically, the azimuth angle of the evaluation sector can be the angle between the center line of the evaluation sector and a unified reference direction, and the angle covered by the evaluation sector can be determined according to the angle between the center line of the evaluation sector and the unified reference direction. The direction of the center of the area; the azimuth angle of the evaluation sector can also be the angle between multiple sector boundaries of the evaluation sector and the unified reference direction, according to the angle between the multiple sector boundaries of the evaluation sector and the unified reference direction The angle of can determine the direction of the center of the area covered by the evaluation sector.

Exemplarily, the azimuth of the evaluation sector may include: the horizontal angle between the center line of the evaluation sector and the clockwise direction from the true north direction line.

202. Acquire the distance of the evaluation base station according to the coordinates of the fault complaint point and the coordinates of the evaluation base station, and obtain the included angle of the evaluation sector according to the coordinates of the fault complaint point, the coordinates of the evaluation base station, and the azimuth of the evaluation sector.

The evaluation base station distance is the distance between the fault complaint point and the evaluation base station. Since the evaluation sector is located on the evaluation base station, it can be considered that the evaluation base station distance is the distance between the fault complaint point and the evaluation sector. The evaluation sector included angle is used to indicate the angle between the emission direction of the evaluation sector and the evaluation base station complaint point connection line, and the evaluation base station complaint point connection line is the connection line between the coordinates of the fault complaint point and the evaluation base station coordinates.

Specifically, according to the coordinates of the fault complaint point, the coordinates of the evaluation base station, and the azimuth angle of the evaluation sector to obtain the included angle of the evaluation sector, it can be used to obtain the connection line and unification of the complaint point of the evaluation base station based on the coordinates of the fault complaint point and the coordinates of the evaluation base station. At the same time, the azimuth angle of the evaluation sector can also be marked by the angle between the center line of the evaluation sector and the unified reference direction. The angle between the evaluation sector and the angle between the center line of the evaluation sector and the unified reference direction can obtain the evaluation sector angle.

203. Obtain an impact value of the evaluation sector according to the evaluation base station distance and the evaluation sector angle.

Wherein, the evaluation sector impact value is used to indicate the impact of the evaluation sector on the wireless network coverage of the fault complaint point.

Specifically, when the evaluation sector provides wireless network services for users located at fault complaint points, the smaller the distance from the evaluation base station corresponding to the evaluation sector is, the greater the impact of the evaluation sector on the wireless network coverage of the user is. When the evaluation base station distance corresponding to an evaluation sector is smaller than the evaluation base station distances corresponding to other evaluation sectors, the evaluation sector has the greatest impact on the wireless network coverage of users located at fault complaint points.

Similarly, when the evaluation sector provides wireless network services for users located at fault complaint points, the smaller the angle between the evaluation sectors corresponding to the evaluation sector, the greater the impact of the evaluation sector on the wireless network coverage of the user. When the evaluation sector angle corresponding to a certain evaluation sector is smaller than the evaluation sector angles corresponding to other evaluation sectors, the evaluation sector has the greatest impact on the wireless network coverage of users located at fault complaint points.

Therefore, the evaluation sector influence value obtained according to the evaluation base station distance and the evaluation sector angle can be used to evaluate the influence of the evaluation base station distance and the evaluation sector angle on the wireless network coverage of the user located at the fault complaint point. It should be noted that when one of the evaluation base station distance and the evaluation sector angle is fixed, the other one of the evaluation base station distance and the evaluation sector angle is positively correlated with the evaluation sector influence value.

Exemplarily, the evaluation sector influence value S is obtained according to the following formula.

S=w1×L+w2×α

Among them, w1 is the weight value of the evaluation base station distance, L is the evaluation base station distance, w2 is the weight value of the evaluation sector angle, and α is the evaluation sector angle. The evaluation base station distance weight value w1 is used to indicate the weight of the evaluation base station distance when calculating the evaluation sector influence value S, and the evaluation sector angle weight value w2 is used to indicate the evaluation sector angle when calculating the evaluation sector influence value S Weights.

A sector evaluation method provided by an embodiment of the present invention obtains the distance of the evaluation base station and the included angle of the evaluation sector by acquiring and according to the acquired coordinates of the fault complaint point, the coordinates of the evaluation base station, and the azimuth angle of the evaluation sector, that is, obtaining The distance between the fault complaint point and the evaluation sector and the angle between the emission direction of the evaluation sector and the connection line of the evaluation base station complaint point, because when the distance between the fault complaint point and the evaluation sector is smaller, the evaluation sector The greater the impact on the wireless network coverage of users located at the fault complaint point; similarly, when the angle between the emission direction of the evaluation sector and the connection line of the evaluation base station complaint point is smaller, the evaluation sector has a greater impact on the users located at the fault complaint point. The influence of the user's wireless network coverage is greater, so the evaluation indicating the impact of the evaluation base station distance and the evaluation sector angle on the user's wireless network coverage at the fault complaint point can be generated according to the evaluation base station distance and the evaluation sector angle The influence value of the sector can be used to evaluate the impact of the sector on the wireless network coverage of the fault complaint point according to the influence value of the sector.

As shown in Figure 3, an embodiment of the present invention provides a sector evaluation method, including:

Specifically, the coordinates of the fault complaint point can be used as the center of the circle, and the preset radius can be used as the radius to determine a circular area. The circular area can be an evaluation area, and the distance between the evaluation base station and the fault complaint point in the evaluation area is less than the preset radius. The evaluation area can also be obtained in other ways, as long as the distance between the evaluation base station in the evaluation and the fault complaint point is less than a preset radius.

302. Acquire the coordinates of the evaluation base station in the evaluation area and the azimuth of the evaluation sector in the evaluation area.

304. Acquire the evaluation sector influence value of the evaluation sector in the evaluation area according to the evaluation base station distance of the evaluation base station in the evaluation area and the evaluation sector angle between the evaluation sectors in the evaluation area.

The evaluation sector influence value of the evaluation sector in the evaluation area can be obtained by referring to step 203 in the above embodiment according to the evaluation base station distance of the evaluation base station obtained in step 303 and the evaluation sector angle in the evaluation area.

Exemplarily, the evaluation base station distance α can be obtained according to the coordinates of the fault complaint point and the coordinates of the evaluation base station in the evaluation area; Evaluation sector angle α;

Determine the maximum value L _max of the evaluation base station distance L in the evaluation area, and determine the maximum value α _max of the evaluation sector angle α in the evaluation area;

Preferably, the first weight value w1 is 0.5, and the second weight value w2 is 0.5.

Specifically, since the distance between the evaluation base station and the angle between the evaluation sectors have an equal impact on the evaluation sector in some scenarios, it is necessary to adjust the distance between the evaluation base station and the angle between the evaluation sectors by setting the corresponding weight value. The weight of the area's influence value.

305. Sort the evaluation sectors according to the evaluation sector influence value;

Specifically, since the sector influence value can be used to indicate the influence of the evaluation sector on the wireless network coverage of the fault complaint point. Therefore, the evaluation sectors can be sorted according to the impact value of the evaluation sectors, and the evaluation sectors that have less impact on the wireless network coverage of the fault complaint point are in a lower position in the evaluation sectors after sorting.

The evaluation sector corresponding to the zone influence value.

306. Adjust the settings of the antennas corresponding to the sorted evaluation sectors in sequence.

Specifically, since the evaluation sectors at the earlier position in the sorted evaluation sectors have a greater impact on the wireless network coverage of the fault complaint point, the evaluation sector at the earlier position in the sorted evaluation sectors is preferentially adjusted The setting of the corresponding antenna in the zone can quickly improve the wireless network coverage problem at the fault complaint point. Adjust the antenna settings corresponding to the sorted evaluation sectors in turn, and can give priority to adjusting the antenna settings corresponding to the evaluation sectors that have a greater impact on the wireless network coverage of fault complaint points, thereby minimizing the wireless network coverage problems that occur at fault complaint points time required.

The greater the influence of coverage; similarly, when the angle between the emission direction of the evaluation sector and the connection line of the complaint point of the evaluation base station is smaller, the greater the impact of the evaluation sector on the wireless network coverage of users located at the fault complaint point, Therefore, it can be used to indicate the distance of the evaluation base station in the evaluation area and the evaluation sector interval of the evaluation sector in the evaluation area based on the evaluation base station distance of the evaluation base station in the evaluation area and the evaluation sector angle of the evaluation sector in the evaluation area.

Wherein, the evaluation base station is the base station where the evaluation sector is located, and the evaluation sector is the sector evaluated according to the sector evaluation method provided in the embodiment of the present invention. Since the evaluation sector is on the evaluation base station, the coordinates of the evaluation base station can be considered as The coordinates of the evaluation sector.

Specifically, the coordinates of the fault complaint point can be the coordinates of the complaining user, and the complaining user is the user who generates or reports complaint data, and the location of the user who generates or reports the number of complaints can be obtained according to the coordinates of the fault complaint point. The coordinates of the evaluation base station may be the coordinates of the base station where the evaluation sector is located, and the location of the base station where the evaluation sector is located can be determined according to the coordinates of the evaluation base station. It should be noted that there may be only one evaluation sector on the evaluation base station, or there may be multiple evaluation sectors. Preferably, each evaluation base station is provided with three evaluation sectors.

The azimuth angle of the evaluation sector is used to indicate the emission direction of the evaluation sector, wherein the emission direction of the evaluation sector is the central direction of the coverage area of the evaluation sector.

Specifically, the azimuth angle of the evaluation sector can be the angle between the center line of the evaluation sector and a unified reference direction, and the angle covered by the evaluation sector can be determined according to the angle between the center line of the evaluation sector and the unified reference direction. The direction of the center of the area; the azimuth angle of the evaluation sector can also be the angle between multiple sector boundaries of the evaluation sector and the unified reference direction, according to the angle between the multiple sector boundaries of the evaluation sector and the unified reference direction The angle of can determine the direction of the center of the area covered by the evaluation sector.

Exemplarily, the azimuth of the evaluation sector may include: the horizontal angle between the center line of the evaluation sector and the clockwise direction from the true north direction line.

The connection line of the evaluation base station complaint point is the fault complaint point The connection line between the coordinates of and the coordinates of the evaluation base station;

The evaluation sector influence value is obtained according to the evaluation base station distance and the evaluation sector angle, and the evaluation sector influence value is used to indicate the influence of the evaluation sector on the wireless network coverage of the fault complaint point.

The evaluation base station distance is the distance between the fault complaint point and the evaluation base station. Since the evaluation sector is located on the evaluation base station, it can be considered that the evaluation base station distance is the distance between the fault complaint point and the evaluation sector. The evaluation sector included angle is used to indicate the angle between the emission direction of the evaluation sector and the evaluation base station complaint point connection line, and the evaluation base station complaint point connection line is the connection line between the coordinates of the fault complaint point and the evaluation base station coordinates.

The evaluation sector corresponding to the zone influence value.

Specifically, since the evaluation sectors at the earlier position in the sorted evaluation sectors have a greater impact on the wireless network coverage of the fault complaint point, the evaluation sector at the earlier position in the sorted evaluation sectors is preferentially adjusted The setting of the corresponding antenna in the zone can quickly improve the wireless network coverage problem at the fault complaint point. Adjust the antenna settings corresponding to the sorted evaluation sectors in turn, and can give priority to adjusting the antenna settings corresponding to the evaluation sectors that have a greater impact on the wireless network coverage of fault complaint points, thereby minimizing the wireless network coverage problems that occur at fault complaint points time required.

The greater the influence of coverage; similarly, when the angle between the emission direction of the evaluation sector and the connection line of the complaint point of the evaluation base station is smaller, the greater the impact of the evaluation sector on the wireless network coverage of users located at the fault complaint point, Therefore, it can be used to indicate the distance of the evaluation base station in the evaluation area and the evaluation sector interval of the evaluation sector in the evaluation area based on the evaluation base station distance of the evaluation base station in the evaluation area and the evaluation sector angle of the evaluation sector in the evaluation area. The evaluation sector influence value of the evaluation sector in the evaluation area on the impact of the angle on the wireless network coverage of the user located at the fault complaint point, so that the evaluation sector in the evaluation area can be evaluated according to the evaluation sector influence value of the evaluation sector in the evaluation area The impact of the zone on the wireless network coverage of the fault complaint point.
