Next, a signal coverage method based on a reconfigurable antenna in the present exemplary embodiment will be further described.

As described in the step S110, the positions and the signal coverage directions of the sectors of the mobile communication base station are obtained, and the number of times of service withdrawal, the duration of service withdrawal, the average load in busy hours and the complaint amount of users of the sectors of the mobile communication base station in a preset period are obtained.

Acquiring the position and signal coverage direction of each mobile communication base station sector, and the number of times of service withdrawal, the duration of service withdrawal, the average load in busy hours and the complaint quantity of users of each mobile communication base station sector in a preset period; wherein, the position refers to the geographic position or coordinate of the mobile communication base station sector, preferably the antenna coordinate of the mobile communication base station sector, and is used for determining the specific position of the mobile communication base station sector in space; the signal coverage direction refers to the antenna radiation direction of the mobile communication base station sector, and is used for determining the coverage direction of wireless signals in the mobile communication base station sector; the number of times of service withdrawal refers to the number of times of signal deletion caused by equipment failure, maintenance or other reasons in a preset period of time by the mobile communication base station sector; the time length of the service withdrawal refers to the total time of signal deletion of the sector of the mobile communication base station in a preset time period, and when the number of times of the service withdrawal is more than once, the time length of the service withdrawal is the sum of a plurality of sections of service withdrawal time; the busy hour average load refers to average communication flow or connection number carried by the mobile communication base station sector in a preset busy period, and reflects the service condition and load capacity of the mobile communication base station sector; the user complaint quantity refers to the complaint quantity of the user on the service quality or other problems of the mobile communication base station sector, and reflects the evaluation and feedback of the user on the performance of the mobile communication base station sector.

And step S120, determining a high-risk base station sector from the mobile communication base station sectors according to the number of times of service withdrawal, the duration of service withdrawal, the average load during busy hours and the complaint amount of users.

And carrying out weighted summation on the number of times of service withdrawal, the duration of service withdrawal, the average load in busy hours and the complaint quantity of the user to obtain the comprehensive score of each mobile communication base station sector. Specifically, assuming that the weight of the number of times of withdrawal is W1, the weight of the duration of withdrawal is W2, the weight of the average load during busy hours is W3, and the weight of the complaint volume of the user is W4, the composite score= (number of times of withdrawal W1) + (duration of withdrawal W2) + (average load during busy hours W3) + (volume of complaint of the user W4).

And setting the mobile communication base station sector with the comprehensive score larger than a preset scoring threshold as the high-risk base station sector. And if the comprehensive score is larger than the preset score threshold, marking the mobile communication base station sector as the high-risk base station sector.

It should be noted that the number of times of withdrawal, the length of withdrawal, the average load in busy hours, the weight of the complaint volume of the user, and the specific value of the preset scoring threshold need to be determined according to actual requirements and service conditions, and can be continuously adjusted and optimized in the actual application process.

Determining, from the mobile communication base station sectors, a succession base station sector corresponding to each of the high-risk base station sectors according to the position and the signal coverage direction as described in step S130; wherein one of the high-risk base station sectors corresponds to at least one of the successor base station sectors; and the successor base station sector is provided with reconfigurable antennas capable of adjusting antenna parameters and the number of antennas.

The signal coverage direction is set to correspond to the Gao Weiji station sector, and the mobile communication base station sector to which the reconfigurable antenna is mounted is set as an alternative base station sector corresponding to the Gao Weiji station sector. Specifically, for each high-risk base station sector, at least one candidate base station sector corresponding to the high-risk base station sector is determined from the rest of the mobile communication base station sectors except the high-risk base station sector, and if the signal coverage direction of the mobile communication base station sector is the same as that of the high-risk base station sector and the reconfigurable antenna is installed, the mobile communication base station sector is marked as the candidate base station sector corresponding to the high-risk base station sector. The reconfigurable antenna is an antenna system which can adjust the antenna parameters and the number of antennas according to the requirement, and can flexibly configure different numbers of antennas and the parameters of the antennas so as to realize better signal coverage and capacity management. As an example, the antenna parameters include reflection plane, beamforming, polarization, and carrier frequency number; the number of antennas includes a number of transmit antennas and a number of receive antennas. By changing the structure of the reconfigurable antenna, one or more of parameters such as a reflecting surface, beam forming, polarization mode, carrier frequency number and the like of the antenna are reconfigured, and/or the number of transmitting antennas and the number of receiving antennas are increased/decreased (activated/dormant), the gain of the reconfigurable antenna in the coverage direction of sector signals can be improved, and the mobile communication capacity of the sector can be improved. The antenna radiation direction of the alternative base station sector is the same as that of the high-risk base station sector, so that signal coverage of the alternative base station sector and the high-risk base station sector can be realized conveniently through antenna reconstruction.

And setting the preset number of the candidate base station sectors closest to the high-risk base station sector as the successor base station sectors corresponding to the high-risk base station sectors. Specifically, all the alternative base station sectors are ordered according to the sequence from small to large with the high-risk base station sector distance, and the former preset number of alternative base station sectors in the ordering result are marked as the successor base station sectors corresponding to the high-risk base station sectors. The successor base station sector is closer to the high-risk base station sector, and the cost required by the antenna reconstruction process is lower.

When the signal of the high-risk base station sector is missing, the final mobile communication usage capacity of the high-risk base station sector before the signal is missing and the real-time mobile communication usage capacity of the successor base station sector corresponding to the high-risk base station sector are obtained as in step S140.

When the signals of the high-risk base station sector are lost, acquiring the final mobile communication service capacity of the high-risk base station sector before the signals are lost and the real-time mobile communication service capacity of the successor base station sector corresponding to the high-risk base station sector; wherein the final mobile communication usage capacity refers to the data amount transmitted in the high-risk base station sector or the number of users using mobile communication services, which are finally recorded before the Gao Weiji station sector signal is lost; the real-time mobile communication usage capacity refers to the amount of data transmitted in the succeeding base station sector or the number of users using mobile communication services, which are recorded when the high-risk base station sector signal is absent.

As described in the step S150, an optimal successor base station sector is determined from the successor base station sectors according to the location of the Gao Weiji station sector and the final mobile communication usage capacity, and the location of the successor base station sector and the real-time mobile communication usage capacity.

And setting the successor base station sector, of which the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity is smaller than or equal to a preset capacity threshold, as an effective successor base station sector. Specifically, if the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity is less than or equal to the preset capacity threshold, the successor base station sector is marked as the valid successor base station sector. The maximum mobile communication capacity obtained by the effective successor base station sector through antenna reconstruction can meet the mobile communication capacity requirements of the effective successor base station sector and the high-risk base station sector.

And setting the effective successor base station sector closest to the high-risk base station sector as the optimal successor base station sector. Specifically, all the effective successor base station sectors are ordered according to the sequence from small to large distance from the high-risk base station sector, and the first ordered effective successor base station sector is marked as the optimal successor base station sector. The optimal successor base station sector is closest to the Gao Weiji station sector, and the cost required by the antenna reconstruction process is the lowest.

And (S160) adjusting antenna parameters and the number of antennas of the reconfigurable antenna of the optimal relay base station sector, so that the reconfigurable antenna performs signal coverage on the optimal relay base station sector and the high-risk base station sector.

And adjusting the reflecting surface, beam forming and polarization modes of the reconfigurable antenna to enable the gain of the reconfigurable antenna in the signal coverage direction of the high-risk base station sector to be improved and the mobile communication capacity to be increased until a first adjusting sector formed by the reconfigurable antenna covers the optimal succeeding base station sector and the high-risk base station sector, and the first adjusting mobile communication capacity of the first adjusting sector reaches the sum of the real-time mobile communication service capacity and the final mobile communication service capacity.

Specifically, one or more of reflection surface adjustment, beam forming adjustment and polarization mode adjustment are adopted, so that the gain of the reconfigurable antenna in the signal coverage direction of the high-risk base station sector is improved and the mobile communication capacity is increased until a first adjustment sector formed by the reconfigurable antenna covers the optimal relay base station sector and the high-risk base station sector, and the first adjustment mobile communication capacity of the first adjustment sector reaches the sum of the real-time mobile communication service capacity and the final mobile communication service capacity; wherein the reflecting surface adjusting means adjusting the reflecting surface shape of the reconfigurable antenna, for example, adopting a convex surface to focus a beam; the beam forming adjustment comprises phase adjustment and amplitude adjustment, wherein the phase adjustment is used for controlling the beam pointing direction by adjusting the phase difference of each unit in the antenna array, the phase adjustment can realize the electronic scanning of the beam, so that the beam has higher gain in the required direction, and the amplitude adjustment is used for changing the main lobe width and the side lobe level of the beam by adjusting the amplitude of each unit in the antenna array, so that the gain in the appointed direction can be improved by increasing the main lobe amplitude; the polarization mode adjustment includes adjustment from linear polarization to circular polarization, and adjustment from circular polarization to circular polarization, and the linear polarization to circular polarization adjustment means converts a linearly polarized beam into circular polarization by adding a phase difference device or a rotator, which conversion can reduce multipath interference in signal transmission and improve reception sensitivity in a specified direction.

When the first adjustment sector reaches the farthest and still cannot cover the optimal successor base station sector and the high-risk base station sector, or the first adjustment mobile communication capacity reaches the largest and still is smaller than the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity, adjusting the number of transmitting antennas and the number of receiving antennas of the reconfigurable antenna so that the gain of the reconfigurable antenna in the signal coverage direction of the high-risk base station sector is increased and the mobile communication capacity is increased until a second adjustment sector formed by the reconfigurable antenna covers the optimal successor base station sector and the high-risk base station sector, and the second adjustment mobile communication capacity of the second adjustment sector reaches the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity. It should be noted that, while adjusting the number of transmitting antennas and the number of receiving antennas of the reconfigurable antenna, the rate of the corresponding CPRI (Common Public Radio Interface ) or eCPRI (enhanced CPRI, common public radio interface) needs to be increased.

Specifically, when the first adjustment sector reaches the farthest and still cannot cover the optimal successor base station sector and the high-risk base station sector, or the first adjustment mobile communication capacity reaches the largest and still is smaller than the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity, the number of transmitting antennas and the number of receiving antennas of the reconfigurable antennas are newly increased at the same time, the number of transmitting antennas and the number of receiving antennas of the reconfigurable antennas are increased from a low gear to a high gear, for example, from 2T2R to 4T4R, 8T8R, 16T16R, 32T32R, 64T64R, 128T128R, etc. (T represents a transmitting antenna, R represents a receiving antenna), while increasing the rate of the corresponding CPRI or eCPRI, and so on until the second adjustment mobile communication capacity of the second adjustment sector reaches the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity.

Specifically, when the second adjustment mobile communication capacity reaches the maximum and is still smaller than the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity, the optimal relay base station sector is controlled to increase or aggregate new carrier frequencies, for example, the frequency bands of 1800MHz, 1900MHz, 2100MHz, 2300MHz, 2500MHz and 2600MHz are increased on the basis of the frequency bands of 700MHz, 800MHz, 850MHz and 900MHz, and simultaneously, the radio frequency transceiver unit of the corresponding carrier frequency is started, so that the mobile communication capacity of the reconfigurable antenna in the signal coverage direction of the high-risk base station sector is increased until the third adjustment mobile communication capacity of the third adjustment sector formed by the reconfigurable antenna reaches the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity.

Further, the step of adjusting the number of transmitting antennas and the number of receiving antennas of the reconfigurable antenna and the step of adjusting the number of carrier frequencies of the reconfigurable antenna may be performed in parallel and synchronously, so as to achieve that the adjusted mobile communication capacity of the optimal succeeding base station sector reaches the sum of the real-time mobile communication usage capacity and the final mobile communication usage capacity.
