Those skilled in the art will appreciate that the terminal structure shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, the memory 1005, which is a kind of computer storage medium, may include therein an operating system, a network communication module, a user interface module, and a router signal overlay adjustment program.
In the terminal shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to invoke the router signal overlay adjustment program stored in the memory 1005 and perform the following operations:
detecting the signal quality of an uplink signal sent by a terminal connected with a router network;
when the signal quality of the uplink signal of the terminal is detected to be smaller than a preset threshold value, adjusting a phase angle of a router antenna;
and when the signal quality of the uplink signals of each terminal is detected to be greater than or equal to a preset threshold value, stopping adjusting the phase angle of the router antenna.
Further, the processor 1001 may call the router signal overlay adjustment program stored in the memory 1005, and also perform the following operations:
when the signal quality of the uplink signal of the terminal is detected to be smaller than a preset threshold value, measuring to obtain an antenna with the highest uplink signal quality and setting the antenna as a target antenna;
and sequentially and positively adjusting the phase angles alpha, beta and gamma of the target antenna in the x, y and z three axes to preset step lengths, and simultaneously detecting the signal quality change of the uplink signal.
Referring to fig. 2, a first embodiment of the present invention provides a router signal coverage adjusting method, where the router signal coverage adjusting method includes the following steps:
step S10, detecting the signal quality of the uplink signal sent by the terminal connected with the router network;
step S20, when detecting that the signal quality of the terminal uplink signal is less than a preset threshold value, adjusting the phase angle of the router antenna;
and step S30, when the signal quality of the uplink signal of each terminal is detected to be greater than or equal to the preset threshold value, stopping adjusting the phase angle of the router antenna.
Specifically, when the terminal device is connected to the router network, the uplink SIGNAL sent by the terminal is detected, and whether the quality of the uplink SIGNAL is smaller than a preset threshold is determined, where the preset threshold may be determined by whether an SNR (SIGNAL-to-NOISE RATIO) value of the uplink SIGNAL is smaller than a preset SNR value. When the signal quality of the uplink signal is less than the preset threshold, it means that the signal quality of the uplink signal of the terminal has affected the internet experience of the user, and therefore the signal problem of the terminal needs to be improved by adjusting the phase angle of the antenna. And after the antenna phase angle is adjusted, if the signal quality of the uplink signal of the terminal is greater than or equal to a preset threshold value, it indicates that the user can not be obviously influenced by surfing the Internet through the terminal at the moment, and therefore, the adjustment of the antenna phase angle is stopped.
When a router or a small-sized base station is used in a network sharing signal (e.g., a wireless network signal) transmitting device suitable for a small-sized application scenario of a home (currently, the router is mainly used, so the present invention introduces a case of using the router, and other devices that transmit a network sharing signal through an antenna are also suitable for the antenna adjusting method of the present invention), the network sharing signal is affected by factors such as a distance, a position, and an obstacle between a transmitting end and a receiving end of the signal, so that the internet access quality of a terminal (e.g., a terminal device used daily such as a smart phone and a tablet computer) is not guaranteed. For example, in a home, multiple persons share internet through a router, the router is placed in a hall, and users use a terminal connection network in each room to access the internet. At this time, the terminal in the room needs to perform multiple reflections to enable the router antenna to receive the uplink signal (the current signal has poor penetration capability to a cement wall used in a building, so that signal transmission is mainly realized through multiple reflections instead of directly penetrating the wall).
The signal quality of the uplink signal after multiple reflections is inevitably affected, when the signal quality is lower than a preset threshold, a user may have a situation of poor network quality (for example, a phenomenon of blocking, an obvious reduction in network speed, and the like), and the situation may be specifically determined by a numerical value of a signal-to-noise ratio of the uplink signal received by the antenna, and when the signal quality of the uplink signal is lower than the preset threshold, it indicates that the user's internet behavior is significantly affected. At this time, the phase angle of the router antenna is adjusted so as to receive the uplink signal of the terminal at a better phase angle (the principle is that the path from the uplink signal transmitted by the terminal to the antenna is changed by adjusting the phase angle of the antenna so as to find a path with a relatively small number of reflections and a short total distance), so that the signal quality of the uplink signal can be effectively improved under the condition that the positions of the terminal and the router are not changed (see fig. 6 for a schematic diagram). And stopping adjusting the phase angle of the antenna until the signal quality of the terminal uplink signal received by the antenna is greater than or equal to a preset threshold when the antenna is at a certain phase angle.
In small application scenes such as families and the like, when the shortest straight path between the terminal and the router antenna is shielded by an obstacle (namely, a signal needs to be reflected or even reflected for multiple times to connect the terminal and the router antenna), the signal quality of the terminal is effectively improved by adjusting the router antenna. And when the signal quality of the uplink signal of the terminal is detected to be smaller than a preset threshold value, starting to adjust the phase angle of the antenna. Therefore, the system can respond in time when the user feels that the internet surfing quality is not good, quickly solve the problem of the user and ensure the normal use of the user for internet surfing. The adjustment measure is to adjust the phase angle of the antenna of the router, and other settings such as the placement position of the router and the like are not required to be adjusted. Therefore, the adjustment process is simple and quick, the requirement on hardware is low, and only a certain number of antennas are required for the router. The more antennas, the larger the adjustable number range, for example, when the router has only 4 antennas, it is impossible to face the terminal with the number exceeding 4 and needs to be adjusted.
Therefore, the invention is suitable for the situation that the number of the routers with a large number of antennas is large or the number of the accessed terminals is small (generally, when the router is used by taking a family as a unit, the number of the antennas is 8 or more, and most application scenes can be basically met). The principle of how to adjust the phase angle of the antenna to improve the network quality of the terminal is also simpler, namely, a signal transmission path between the terminal and the antenna is changed, the reflection times are reduced to the maximum extent, and the transmission path is reduced, so that the signal quality loss caused by unscientific paths of signals in the transmission process is effectively reduced, and the signal quality is improved. The whole adjustment process does not need manual operation, redundant hardware equipment does not need to be added, the network quality problem of a user can be effectively improved only through the phase angle adjustment of the antenna, for the user, extra cost is avoided, the network quality is improved in use, and the user experience is greatly improved.
Further, referring to fig. 3, in a second embodiment of the method for adjusting signal coverage of a router according to the present invention, step S20 includes:
step S21, when detecting that the signal quality of the uplink signal of the terminal is less than a preset threshold value, measuring to obtain an antenna with the highest uplink signal quality and setting the antenna as a target antenna;
and step S22, sequentially and positively adjusting the phase angles alpha, beta and gamma of the target antenna on the x, y and z axes to preset step lengths, and simultaneously detecting the signal quality change of the uplink signal.
Specifically, when the signal quality of the uplink signal of the terminal is detected to be smaller than the preset threshold, it indicates that the network quality is possibly poor, and therefore, the antenna phase angle is adjusted to solve the network quality problem. Generally speaking, because the router has a plurality of antennas, when adjusting the antennas, it is not necessary to adjust all the antennas, and only one antenna needs to be adjusted to meet the requirement that the signal quality of the uplink signal of the terminal is greater than or equal to a preset threshold. Therefore, before adjusting the antenna phase angle, it is first necessary to determine which antenna to specifically adjust. The initial positions of the antennas are different, so that the signal quality of the uplink signal of the terminal detected by each antenna is different, and the final purpose of adjusting the antenna phase angle is to improve the quality of the uplink signal of the terminal, so that the purpose of adjusting the phase angle of the antenna with the highest signal quality of the detected uplink signal of the terminal can be achieved most quickly. As in the example shown in table 1, the antenna 1 is a target antenna that needs to be phase angle adjusted. Assuming that the SNR values of the uplink signals of the terminal measured by each antenna are as shown in table 1:
TABLE 1
When the phase angle is adjusted, the phase angles alpha, beta and gamma of the three axes x, y and z are adjusted in sequence, and the preset length is adjusted each time. For example, if the preset step size is 2, the initial values of α, β, and γ are 45 °,45 °,45 °, respectively, then the first adjustment adjusts α forward by 2, where α, β, and γ are 47 °,45 °,45 °, respectively, and the second adjustment adjusts β forward by 2, where α, β, and γ are 47 °,47 °, and 45 °, respectively. And adjusting gamma according to the preset step length for the third time, and continuously adjusting alpha for the fourth time. And simultaneously, detecting the signal quality change of the uplink signal after each adjustment so as to judge whether the adjustment direction is correct or not.
Since there are a plurality of antennas of the router, when determining that the phase angle of the antenna needs to be adjusted, it is the first choice to determine which antenna or antennas need to be adjusted. When the signal quality of the uplink signal of only a single terminal is less than the preset threshold, the reception of the multiple antennas and the reception of the single antenna have no great influence on the transmission of the uplink signal of the terminal, so that the normal requirement of the terminal on the network use can be met only by adjusting one antenna until the signal quality of the uplink signal of the terminal is greater than or equal to the preset threshold, and the terminal is set as a target terminal. After determining the number of antennas that need to be adjusted, it is then necessary to determine which antenna to specifically adjust. The purpose of adjusting the antenna is to improve the signal quality of the uplink signal of the terminal to be equal to or greater than a preset threshold, so that the value needs to be increased to be the difference between the preset threshold and the current value, and thus, the higher the signal quality of the current uplink signal is, the smaller the value needs to be increased by adjustment, so that the signal quality of the uplink signal of the terminal to each antenna at present is detected, the antenna with the highest signal quality of the uplink signal is used as a target antenna to perform phase angle adjustment, and the antenna is changed to be the target antenna corresponding to the target terminal. For example, currently, three antennas a, B, and C exist, SNR values of uplink signals of the terminal are respectively detected to be 7dB, 8dB, and 9dB, and the preset threshold is 10 dB. The corresponding values of the signal quality to be improved are 3dB, 2dB and 1dB, so that the adjustment of the C antenna can more conveniently and quickly enable the signal quality of the uplink signal of the terminal to reach the purpose of being more than or equal to the preset threshold value. When the phase angle of the antenna needs to be adjusted, the target antenna needing to be adjusted is automatically judged according to the signal quality of the detected uplink signal, and the aim of improving the network quality of the terminal is fulfilled at the minimum cost.
Further, step S22 includes:
step S221, sequentially and positively adjusting the phase angles alpha, beta and gamma of the target antenna in the x, y and z three axes to preset step length, and detecting the signal quality of the uplink signal after each positive adjustment of the phase angle of the target antenna;
step S222, after the phase angle of the target antenna is adjusted, if the signal quality of the uplink signal is detected to be improved, the preset step length adjustment in the same direction is carried out again;
in step S223, if the signal quality of the uplink signal is detected to be degraded, the corresponding forward adjustment is changed to a reverse adjustment preset step length.
Specifically, when the phase angle of the target antenna is adjusted, the signal quality of the uplink signal of the terminal is detected after each adjustment, so as to observe the influence of the adjustment of the phase angle on the uplink signal. If the detection finds that the signal quality of the uplink signal is increased, the adjustment of the phase angle is indicated and the adjustment direction is the correct direction, so that the adjustment of the phase angle in the same direction is continued. If the quality of the new and good uplink signal is detected to be reduced, the phase angle is adjusted in a direction away from the target, and therefore the phase angle is continuously adjusted after the adjusting direction is changed.
When the target antenna phase angle is adjusted, the correct direction of adjustment cannot be accurately obtained at the first time, so the adjustment strategy is to firstly perform forward adjustment on alpha, beta and gamma (the front, the left and the upper parts of the router are respectively the forward directions of x, y and z axes), and detect the signal quality gain condition of an uplink signal brought by the forward adjustment of the target antenna phase angle. When positive gain is brought by the positive adjustment (the signal quality of the uplink signal is improved), the positive adjustment of the target antenna phase angle is continued. If negative gain occurs (which is manifested as a decrease in the signal quality of the uplink signal), the phase angle of the target antenna is adjusted in the opposite direction. Assume that the data statistics for a certain adjustment are as in table 2:
TABLE 2
For example, the SNR value of the uplink signal of the target terminal initially measured by the target antenna is 9.5dB, α, β, and γ are 45 °,45 °, and 45 °, respectively, and the preset step size is 2, and first, α is adjusted by 2 in the forward direction, and α, β, and γ are 47 °,45 °, and 45 °, respectively after adjustment. At this time, the measured signal quality of the uplink signal of the target terminal is 9.2dB, which indicates that the positive gain is brought by the positive adjustment of the x axis, so that the positive adjustment is continued in the x axis direction. And then adjusting the beta positively by 2, wherein the alpha, the beta and the gamma are respectively 47 degrees, 47 degrees and 45 degrees, and the signal quality of the uplink signal is measured to be 9.1dB, which indicates that the positive adjustment of the y axis brings negative benefit, and the y axis changes the adjustment direction of the phase angle into negative adjustment. When the phase angle of the target antenna is adjusted, whether the adjustment direction is changed or not is determined by monitoring whether the effect of the phase angle adjustment is positive gain or negative gain. The method determines the adjusting direction, has simple principle and easy operation, and greatly increases the adjusting efficiency of the phase angle.
Further, referring to fig. 3, a third embodiment of the method for adjusting signal coverage of a router according to the present invention includes, after step S223:
step S224, when it is detected that the signal quality of the uplink signal does not increase with the adjustment of the phase angle, the antenna phase adjustment is completed;
step S225, detecting α, β, γ corresponding to the peak of the uplink signal quality during the adjustment process as the optimal phase angle of the antenna, and adjusting the phase angle of the antenna to the optimal phase angle of the antenna.
Specifically, when it is detected that the signal quality of the uplink signal has decreased again after the direction conversion, the phase angle of the axis is not changed. And after the phase angles of the three axes are all stopped to be adjusted, adjusting the phase angle of the antenna to the angle position corresponding to the peak value of the uplink signal.
In the process of adjusting the phase angle of the target antenna, after the adjusting direction is determined, the preset step length is continuously adjusted in the direction which brings positive benefits, and after negative benefits are detected, the adjusting direction is switched to the opposite direction to continue adjusting. When the direction is converted and then the adjustment is detected again to bring negative benefits, the optimal position of the target antenna on the axis is shown, so that the adjustment of the axis can be stopped, the angle position corresponding to the signal quality peak value of the uplink signal is recorded, and then the target antenna is adjusted to the corresponding position. Thus, when the three axes x, y and z are adjusted to the optimal position, the antenna is at the optimal phase angle.
For example, when the target antenna is at an initial x-axis position α of 45 °, the first adjustment is a forward adjustment by a preset step size of 2, to 47 °, and a negative gain occurs. And the adjustment direction is switched for the second time, the adjustment is performed towards the negative direction 2, the positive income is generated, and then the negative adjustment is continued. When negative adjustment is performed for multiple times, the phase angle of the target antenna on the x axis is 35 degrees, negative benefits are generated after adjustment is performed again, and the optimal position of the target antenna on the x axis can be determined when alpha is equal to 35 degrees. And adjusting corresponding phase angles of beta and gamma of the Y axis and the z axis in the same way until the optimal positions of the x axis, the Y axis and the z axis are all found out, and at the moment, the optimal positions of the three axes corresponding to the alpha, beta and gamma are the optimal phase angles of the target antenna.
The invention has simple and practical logic for searching the optimal phase angle, is easy to realize and has better effect, and can efficiently finish the discovery of the most phase angle (reverse adjustment is carried out at the first time after negative income occurs, thereby avoiding excessive adjustment in the wrong direction continuously), thereby efficiently finishing the phase angle adjustment of the target antenna with high quality.
Further, referring to fig. 4, the antenna adjusting method further includes: :
step S41, when detecting that the quality of the uplink signals of the multiple terminals is less than the preset threshold value, if the target antennas corresponding to the uplink signals of the multiple terminals are the same antenna, the terminal with the highest quality of the uplink signals received by the target antenna is the target terminal corresponding to the target antenna; and after the target antenna is set, performing preset step length adjustment on the phase angle of the target antenna by taking the target terminal as a reference.
Specifically, when the signal quality of uplink signals of multiple terminals is smaller than a preset threshold, that is, multiple antennas need to be adjusted, the terminals need to be in one-to-one correspondence with the antennas, and one target antenna corresponds to one target terminal. The corresponding principle is the same as that of a single terminal, namely the antenna with the highest signal quality of the uplink signal of the target terminal is detected as the target antenna. When the antennas with the highest quality of uplink signals of the plurality of terminals are the same antenna, the antenna takes the terminal with the highest quality of the detected uplink signals as a target terminal, and the rest of the terminals determine the target antenna according to the signal quality of the uplink signals in the rest of the antennas.
When a plurality of terminals are faced, the problem that the plurality of terminals correspond to the antenna is firstly solved, namely, the target antenna corresponding to the target terminal is determined. When a single terminal is processed, the target antenna is determined according to the signal quality of the uplink signal of the target terminal received by the antenna, and the antenna with the highest signal quality of the received uplink signal is the target antenna. When there are multiple terminals, the target antenna can still be determined by the antenna with the highest signal quality of the received uplink signal. However, when the target antennas of the plurality of terminals are all the same antenna, the terminal with the higher uplink signal received by the target antenna is taken as the corresponding target terminal. And the other terminals determine the target antenna from the rest antennas. The measured SNR values for each antenna for a multi-terminal scenario are given in table 3:
TABLE 3
For example, currently, there are four antennas 1, 2, 3, and 4, and when it is monitored that the signal quality of uplink signals of two terminals a and B is less than a preset threshold (the threshold is 10dB), it is first measured that the signal quality of uplink signals of a and B received by the antennas 1, 2, and 3, and 4 are respectively: antenna 1 (terminal A: 9.5dB, terminal B: 9.2dB), antenna 2 (terminal A: 8.5dB, terminal B: 9.0dB), antenna 3 (terminal A: 7dB, terminal B: 8.2dB), antenna 4 (terminal A: 5dB, terminal B: 6.3 dB). At this time, when the antennas with the highest uplink signal quality of the terminal a and the terminal B are both the antenna 1, the signal quality of the uplink signals of the terminal a and the terminal B received by the antenna 1 are continuously compared, and the received uplink signal quality (9.5dB) of the terminal a is found to be greater than the uplink signal quality (9.2dB) of the terminal B, so that the antenna a is set as the target antenna corresponding to the terminal a. At this time, the terminal B determines a target antenna at an antenna other than the antenna 1 according to the antenna with the highest signal quality of the received uplink signal, and finds that the uplink signal of the terminal B received by the antenna 2 is the highest signal quality except the antenna 1, so that the antenna 2 is the target antenna corresponding to the terminal B (see fig. 7 for schematic diagram).
When a plurality of terminals need to adjust the phase angles of corresponding antennas, the invention can process the plurality of terminals at the same time. And respectively determining the target antennas corresponding to the plurality of terminals according to the rules, thereby efficiently finishing the adjustment of the target antennas corresponding to the plurality of terminals.
Further, step S41 is followed by:
step S42, when the target antenna phase angle is adjusted, if the signal quality difference between the signal quality variation of the non-target terminal uplink signal and the signal quality variation of the target terminal uplink signal is smaller than the preset difference, and the number of consecutive occurrences of the signal quality difference smaller than the preset difference along with the adjustment of the target antenna phase angle is greater than the preset number,
step S43, regarding the target terminal and the non-target terminal meeting the conditions as the terminals in the same area, and adjusting the antenna phase angle of the terminal in the same area as a whole; and the non-target terminal which does not meet the condition takes the antenna with the highest uplink signal quality in the antennas except the target antenna as a new target antenna.
In step S44, if the number of consecutive occurrences is not greater than the preset number, the terminals are determined as non-local terminals.
Specifically, when adjusting the phase angles of the target antennas for a plurality of target terminals, respectively, and when it is detected that the adjustment of the same target antenna by the plurality of terminals has the same change trend (including one target terminal corresponding to the target antenna and other non-corresponding target terminals), the plurality of terminals are regarded as the same area terminal, and when adjusting the antenna phase angles, the adjustment of the antenna phase angles is performed on the same area terminal regarded as one individual. If the terminal and the target terminal corresponding to the antenna have the same change trend, namely, the change of the quality of the uplink signal of the received terminal is very close (the change is smaller than a preset difference value) every time the antenna phase angle is adjusted, and the change trend always appears along with the increase of the adjustment times of the antenna phase angle (the continuous times are larger than the preset times), all terminals meeting the conditions and the target terminal corresponding to the antenna are judged to be the terminals in the same area, and the terminals and the target terminal are considered to be integrally subjected to uniform antenna phase angle adjustment.
When the uplink quality of a plurality of terminals is smaller than the preset threshold value, the invention can regard the plurality of terminals with the same change trend as the terminals in the same area besides the measure that the plurality of antennas correspond to the plurality of terminals one by one. When the phase angle of the antenna is adjusted, the terminals in the same area are treated as a whole. The invention mainly uses small scenes such as families and the like, and the scenes corresponding to the terminals in the same region are all terminals in the same cell (when the judgment is that the signal quality of the uplink signal is more than or equal to the preset threshold value, the average value of the quality of the uplink signal of all the terminals in the same region can be used as a reference value, or the signal quality of the uplink signal of the target terminal originally provided by the antenna can be used as the reference value and the like). For example, a plurality of rooms are located in a home, a router is placed in a living room, and if two terminals are connected to a network in different rooms respectively and the signal quality of uplink signals of the two terminals is detected to be smaller than a preset threshold value, a rule that a plurality of antennas correspond to the plurality of terminals one to one is applied to adjustment. And when the two terminals are in the same room and the signal quality of the uplink signal is still detected to be less than the preset threshold value. At this time, if the rule that the plurality of antennas and the plurality of terminals are in one-to-one correspondence is continuously used, the two antennas can be correspondingly adjusted to achieve the expected effect, but because the two terminals in the same room have high similarity of positions, the purpose of adjusting the antenna phase angle is to reduce the loss of the uplink signal transmitted by the terminal in the transmission path, after one antenna is adjusted to the optimal phase angle, the antenna can receive the uplink signal of which the signal quality of all terminals in the room where the corresponding target terminal is located meets the requirement (namely, the signal quality of the uplink signal is greater than or equal to the preset threshold), and the antenna does not need to be separately arranged for other terminals in the room to be adjusted for multiple times. The invention can flexibly process the condition of a plurality of terminals, effectively save time and antenna resources when the terminals with similar positions can be reprocessed by setting the same regional concept, and improve the efficiency of adjusting the phase angle of the antenna.
Further, referring to fig. 5, step S30 is followed by:
and step S50, increasing the power of the antenna at the optimal phase angle, increasing the power of a preset value each time, and simultaneously reducing the power of the other antennas by the preset value until the block error rate of the downlink signal of the target terminal reaches a preset standard, wherein the antenna at the optimal phase angle is the antenna which adjusts the phase angle and then enables the quality of the uplink signal of the corresponding target terminal to reach the optimal quality.
Specifically, after the antenna adjusts the phase to the optimal position, it indicates that the received uplink signal of the terminal meets the standard (the signal quality is greater than or equal to the preset threshold), and at this time, the power of the antenna at the optimal phase angle is increased to reduce the BLER (block error rate) of the downlink signal corresponding to the target terminal. And simultaneously reducing the power of other antennas with the phase angle not adjusted to keep the total power unchanged until the BLER of the downlink signal of the target terminal reaches a preset standard, namely, is smaller than a preset proportion, for example, the preset proportion is 8%, and when the BLER of the target terminal is smaller than 8%, the BLER reaches the preset standard.
After the phase angle of the target antenna corresponding to the target terminal is adjusted, the signal quality of the uplink signal of the target terminal received by the target antenna meets daily normal use. At this time, the power of the target antenna is increased, so that the quality of the downlink signal of the target terminal can be effectively improved, and the internet access quality of the user through the target terminal is obviously improved. The downlink signal of the target terminal is measured by BLER (block error rate). While the target antenna power is increased, the power of the rest antennas is sequentially reduced to keep the total power unchanged (the total power cannot be changed arbitrarily because the total power is limited by conditions such as equipment hardware and the like). For example, there are four antennas, i.e., antenna 1, antenna 2, antenna 3, and antenna 4, where antenna 1 is the target antenna, the preset value is 2, the preset ratio is 8%, and the initial power is 20 dBm. For the first adjustment, the power of the antenna 1 is increased to 22dBm, and the power of the rest antennas is respectively 18dBm, 20dBm and 20 dBm. At this time, if the BLER of the target terminal is greater than 8%, the power continues to be increased. The power of the antenna 1 is increased to 24dBm, and the power of other antennas is respectively 18dBm, 18dBm and 20 dBm. And stopping power adjustment until the BLER of the target terminal is less than 8%.
The signal quality of the target terminal uplink signal is obviously improved by adjusting the antenna phase angle, and the quality of the target terminal downlink signal is improved by increasing the target antenna power. Therefore, the signal quality of the uplink signal and the downlink signal of the target terminal is remarkably improved, the internet access quality of a user is guaranteed, and the use experience of the user is improved.
Further, step S50 further includes:
step S51, when the number of the antennas at the optimal phase angle is multiple, each antenna is independently adjusted in power, and each antenna at the optimal phase angle is adjusted in sequence to enable the downlink signal of the corresponding target terminal to reach the preset standard;
and for the antenna of which the downlink signal of the target terminal reaches the preset standard, keeping the current power unchanged.
Specifically, when there are multiple antennas with adjusted phase angles, the power of all the antennas with adjusted phase angles is adjusted, and the specific adjustment steps are substantially the same as the above-mentioned method for adjusting the power of a single antenna, but when the power of other antennas is reduced, the power of the antennas to be adjusted and that already adjusted is not changed. For the terminals in the same area, the adjustment is still considered as a whole, and the whole completion standard can be determined according to the BLER average value of all terminals in the same area or the target terminal BLER corresponding to the target antenna. And after adjusting all the antenna power required to be adjusted in sequence, detecting that all the corresponding terminal BLERs reach the standard, and then finishing the adjustment. When the problem that a plurality of antennas need to be adjusted is solved, each antenna can be independently adjusted, so that all connected terminals can guarantee the quality of network connection, users can use the terminal normally, and user experience is improved.
