Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
First, a usage scenario of the present disclosure will be explained. The method is mainly applied to a scene of controlling the electromagnetic radiation of the base station, because the bandwidth of the 5G is large and the working frequency is high, compared with the 4G, the 5G base station needs larger transmitting power to meet the service coverage requirement, and the construction density of the 5G base station is higher, in order to prevent the electromagnetic radiation pollution and guarantee the public health, the radiation condition of a sensitive area (such as a building) in the coverage area of the base station needs to be monitored, and the radiation value of the coverage area of the base station is ensured to be lower than a specified preset radiation threshold value so as to avoid the radiation to the human body. Under the condition that a base station uses a highly integrated active antenna and the transmission power is greatly improved, the radiation value in the coverage area of the base station is difficult to meet the existing radiation standard, and particularly for an outdoor macro base station in a large-scale antenna state, the existing industrial capability cannot meet the existing radiation standard in a sensitive area. In the related art, the radiation value can be reduced by reducing the overall transmission power of the base station, but this way reduces the radiation and the use efficiency of the base station, so that the communication service is greatly affected.
In order to solve the above problem, the present disclosure provides a method, an apparatus, a storage medium, and an electronic device for controlling signal radiation, after current signal radiation of a target location area is obtained, target transmission power corresponding to the target location area may be obtained according to the current signal radiation, and signal radiation of the target location area may be reduced according to the target transmission power, so that after the target location area is determined, signal radiation of the target location area may be reduced only according to the target transmission power, so that the signal radiation of the target location area satisfies a radiation standard, and in a coverage area of a base station, transmission powers corresponding to other areas except the target location area remain unchanged, so that a normal service requirement may be ensured, and thus, usage efficiency of the base station may be improved.
The following detailed description is provided for a specific embodiment of the present disclosure with reference to the accompanying drawings, and the technical solutions provided by the following embodiments of the present disclosure may be applied to a wireless communication network, for example: an LTE (Long Term Evolution ) system, an LTE-a (Long Term Evolution Advanced ) system, and further evolved networks thereof, such as a 5G network.
A base station, which may be a device that communicates with user equipment or other communication stations, such as relay stations, and terminals may be included in a wireless communication network. The base station may provide communication coverage in a specific physical area, for example, the base station may specifically be an ENB (evolved Node B) in LTE, or may also be other access network equipment providing access service in a wireless communication network.
Fig. 1 is a flowchart of a method for controlling signal radiation according to an embodiment of the present disclosure, where the method includes the following steps, as shown in fig. 1:
s101, acquiring a target position area to be controlled and current signal radiation of the target position area.
The target location area may be a location area where a radiation value exceeds a preset radiation threshold, the preset radiation threshold may be determined according to a region, and different countries have different regulations on the preset radiation threshold.
In a possible implementation manner, the target location area reported by the user and the current signal radiation of the target location area may be received, or the target location area sent by the network management device and the current signal radiation of the target location area may be received.
The user may be a worker who maintains the network, a monitoring organization that monitors the radiation condition, or a resident who lives in the coverage area of the base station, and the range of the user is not limited here.
For example, for a worker who maintains a network, a sensitive area in a coverage area of the base station may be detected, and when a target location area with a radiation value exceeding a preset radiation threshold is detected, coordinates of the target location area and current signal radiation of the target location area may be reported to the network management device; aiming at a supervision mechanism, the radiation value of a sensitive area in a coverage area of a base station, such as a residential building, a market, a hospital, a factory and the like, can be detected at irregular time, if the radiation value of the sensitive area exceeds a preset radiation threshold value, the sensitive area can be determined to be a target position area, and the position information of the target position area and the current signal radiation of the target position area are sent to network management equipment; aiming at residents in a coverage area of a base station, the radiation value of a resident position area can be detected through detection equipment, and if the radiation value of the position area exceeds a preset radiation threshold value, complaints can be initiated to a supervision organization or a network operator and the like, and a target position area with overproof radiation and current signal radiation of the target position area can be fed back.
And S102, acquiring target transmitting power corresponding to a target position area according to current signal radiation.
The target transmission power may be a maximum transmission power corresponding to the target location area when the radiation signal of the target location area is lower than a preset radiation threshold.
In this step, after receiving the target location area and the current signal radiation of the target location area, the maximum transmission power of the base station for the target location area may be obtained, and then, the transmission power corresponding to the target location area is reduced in an equal ratio according to a difference between the current radiation value of the target location area and a preset radiation threshold, for example, if the initial maximum transmission power is 50dbm, the current signal radiation of the target location area is 15v/m, and the preset radiation threshold is 12v/m, the target transmission power is 47 dbm.
It should be noted that after the network management device obtains the target location area and the current signal radiation of the target location area, the radiation reduction instruction may be sent to the base station corresponding to the target location area, and after the base station receives the radiation reduction instruction, the target transmission power corresponding to the target location area may be obtained.
And S103, reducing the signal radiation of the target position area according to the target transmitting power.
In one possible implementation, the beam power within the target location area may be set to the target transmit power.
Wherein the beam power may be a maximum transmit power of the beam.
After the target transmission power is acquired, a beam of the target location area may be acquired, and the beam power may be set as the target transmission power, so that only the signal radiation of the target location area may be reduced. Here, the beam power of the beam for the other areas except the target location area in the coverage area of the base station is kept unchanged, so as to avoid the problem of abnormal communication service caused by reducing the beam power. Illustratively, the beams of the target location area are beam 2 and beam 3, and the power of beam 2 and beam 3 can be reduced to the target transmit power.
In another possible implementation manner, the beamforming weights in the target location area may be adjusted to reduce the beam power to the target transmission power.
After the target transmitting power is obtained, the beam of the target position area can be obtained, and the beam forming weight of the target position area is adjusted according to the target transmitting power, so that the beam power of the target position area is smaller than or equal to the target transmitting power, and the beam power of the target position area can be reduced to the target transmitting power. Exemplarily, the beams of the target location area are beam 2 and beam 3, and the beamforming weights may be adjusted by a beamforming method in the prior art, so that the beam power of beam 2 and beam 3 is less than or equal to the target transmission power.
By adopting the method, the target position area to be controlled and the current signal radiation of the target position area are obtained, the target transmitting power corresponding to the target position area is obtained according to the current signal radiation, and the signal radiation of the target position area is reduced according to the target transmitting power. Therefore, after the target position area is determined, the signal radiation of the target position area can be reduced only according to the target transmission power, so that the signal radiation of the target position area meets the radiation standard, and in the coverage area of the base station, the transmission power corresponding to other areas except the target position area is kept unchanged, so that the normal communication requirements of other areas can be ensured, and the use efficiency of the base station can be improved while the problem of base station radiation is solved.
Fig. 2 is a flowchart of another method for controlling signal radiation according to an embodiment of the disclosure, and as shown in fig. 2, the method includes the following steps:
s201, receiving the position information reported by the terminal.
The position information includes a distance between the terminal and the base station and an angle between the terminal and the base station.
In this step, the base station may obtain a distance between the terminal and the base station according to the measured reception time of the terminal random access preamble sequence; the distance between the terminal and the base station may also be obtained according to a timing advance TA configured for the terminal, for example, the transmission time of a signal may be obtained through the TA, and the distance between the terminal and the base station may be obtained according to the transmission time and the transmission rate of the signal; the distance between the terminal and the base station can also be obtained through the position information reported by the terminal. In addition, the base station may acquire the angle between the terminal and the base station by using a positioning method such as OTDOA (Observed Time Difference Of Arrival interval), UTDOA (Uplink-Time Difference Of Arrival interval), or the like, may acquire the angle between the terminal and the base station according to a beam identifier configured for the terminal by the base station or a beam identifier corresponding to PRACH selected by the terminal for transmission, and may acquire the angle between the terminal and the base station according to the position information reported by the terminal.
S202, signal radiation of a position area corresponding to the position information is obtained, if the signal radiation of the position area is larger than or equal to a preset radiation threshold value, the position area is determined as a target position area, and the signal radiation of the position area is determined as current signal radiation of the target position area.
In a possible implementation manner, the signal radiation of the target location area may be obtained through a preset radiation association relationship according to the location information.
The radiation association relationship may include a correspondence between the location information and the signal radiation in the coverage area of the base station. The radiation association relationship may be preset at the time of factory shipment of the antenna device, for example, the radiation association relationship may be stored in the server, where the location area may be a location area corresponding to different distances at different radiation angles of the base station, and the radiation angle may be determined according to a coverage range of the antenna, for example, 0 degree, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, or other preset angles, where the range of the radiation angle is not limited; the distance can be determined according to the attenuation condition of the power, and can be 5 meters, 10 meters, 50 meters, 100 meters and the like; the radiation association relationship may also be obtained by field detection by a network planner, for example, after the base station is turned on, the network planner detects location areas corresponding to different distances at different angles of the base station to obtain signal radiation corresponding to different location information in the coverage area of the base station, and stores the correspondence relationship between the location information and the signal radiation, that is, the radiation association relationship in a server.
In this step, after the position information of the terminal, that is, the distance between the terminal and the base station and the angle between the terminal and the base station are obtained, the signal radiation of the position area corresponding to the position information may be obtained through a preset radiation association relationship, and further, if the signal radiation is greater than or equal to a preset radiation threshold, the position area corresponding to the position information is the target position area.
The position information may be specific coordinate information, and for example, the position information may be represented by longitude and latitude corresponding to the position information, and a database may be used to store a correspondence relationship between the coordinate information corresponding to the angle and distance and the signal radiation after detecting the signal radiation in the position area corresponding to the different distance at different angles of the base station in advance. After the position information reported by the terminal is acquired, the signal radiation of the position area corresponding to the position information can be acquired through the radiation association relation according to the coordinate information corresponding to the position information.
In another possible implementation manner, a target coverage area with signal radiation greater than or equal to a preset radiation threshold is determined from a coverage area of a base station, probabilities of the terminal appearing in the target coverage area in different preset time periods are obtained, a target probability greater than or equal to the preset probability threshold is determined from the obtained probabilities, the target coverage area within the target preset time period corresponding to the target probability is determined as a target location area, and the signal radiation of the target coverage area is determined as the current signal radiation of the target location area.
The preset probability threshold may be set according to specific requirements, and may be determined according to the magnitude of the signal radiation exceeding the standard, for example, for a target location area with higher signal radiation exceeding the standard, a lower preset probability threshold may be set, and for a target location area with lower signal radiation exceeding the standard, a higher preset probability threshold may be set.
And for each preset time period, receiving the position information reported by the terminal in the preset time period, and taking the position information as the input of a probability prediction model to obtain the probability of the terminal appearing in the target coverage area.
Wherein, the preset time period may be 20 minutes or 2 hours, and the range of the preset time period is not limited herein; the probabilistic predictive model can be obtained by training through an existing machine learning algorithm.
For each preset time period, a plurality of pieces of location information reported by all terminals in the preset time period may be obtained, for example, 5 pieces of location information reported by terminal a may be obtained, and 3 pieces of location information reported by terminal B may be obtained, and then, the plurality of pieces of location information reported by all terminals are used as input of a probability prediction model, so as to obtain a probability that the terminal appears in a target coverage area in the preset time period, where the target coverage area may include a plurality of location information, for example, the probability of the target coverage area a is 10%, the probability of the target coverage area B is 30%, and the probability of the target coverage area C is 20%.
After obtaining the multiple probabilities of the target coverage area, obtaining the target probability which is greater than or equal to a preset probability threshold, wherein the target coverage area within a target preset time period corresponding to the target probability is the target position area.
S203, obtaining a difference value between the current radiation signal and a preset radiation threshold value, and obtaining target emission power corresponding to a target position area according to the difference value.
In this step, the maximum transmission power of the base station for the target location area may be obtained, and then the target transmission power may be obtained by the following formula:
Rtarget＝Rmax-(R-Rlimit) (1)
wherein R istargetFor a target transmission power, RmaxFor maximum transmitted power, R is the currently radiated signal, RlimitIs a preset radiation threshold.
And S204, reducing the signal radiation of the target position area according to the target transmitting power.
In one possible implementation, the transmission power allocated by the base station to the terminal in the target location area may be reduced according to the target transmission power.
For each terminal in the target location area, calculating to obtain power to be adjusted corresponding to the terminal according to the second transmitting power allocated to the terminal by the base station and the total transmitting power allocated to the plurality of terminals in the target location area by the base station; and taking the power to be adjusted as the transmitting power distributed to the terminal by the base station so as to reduce the transmitting power distributed to the terminal in the target position area by the base station.
After the target transmission Power is obtained, when the base station is at the maximum downlink transmission Power, according to the RSRP (Reference Signal Receiving Power) or SINR (Signal to Interference plus Noise Ratio) reported by each terminal in the target location area and the scheduling request sent by each terminal, the second transmission Power allocated to the terminal at the scheduling time is obtained, and then, according to the obtained second transmission Power of each terminal, the total transmission Power allocated to the plurality of terminals in the target location area by the base station is calculated. Further, the power to be adjusted corresponding to each terminal can be calculated by the following formula:
PUE＝Rtarget*PUE/Rtatal(2)
wherein, PUEFor the power to be regulated, RtargetIs a target transmission power, PUEIs the second transmission power, RtatalIs the total transmit power.
After the power to be adjusted corresponding to each terminal is obtained, the power to be adjusted can be used as the transmission power allocated to the terminal by the base station, so as to reduce the transmission power allocated to the terminal in the target location area by the base station.
In another possible implementation manner, the scheduling time of the base station for the terminal in the target location area may be adjusted according to the target transmission power.
The method comprises the steps that a target terminal supported under target transmitting power can be determined from terminals which are scheduled at a target scheduling time in a target position area; and adjusting the scheduling time of other terminals except the target terminal in the target position area so as to enable the scheduling time of the other terminals to be different from the target scheduling time.
After obtaining the target transmission power and the total transmission power allocated to the plurality of terminals in the target location area by the base station at the maximum downlink transmission power, if the target transmission power is less than the total transmission power, the target terminal supported under the target transmission power may be determined from the terminals scheduled at the target scheduling time in the target location area according to the target transmission power, where the target terminal in the target location area may be determined in various ways, for example, the transmission powers allocated to all terminals by the base station in the target location area may be sorted, and the terminal with the maximum allocated transmission power may be sequentially adjusted to other scheduling times until the sum of the transmission powers of all remaining terminals is less than or equal to the target transmission power, where all remaining terminals are the target terminals, for example, the target transmission power is 47W, the number of terminals in the target position area is 5, the power distributed to the terminal A by the base station is 14W, the power distributed to the terminal B is 12W, the power distributed to the terminal C is 10W, the power distributed to the terminal D is 11W, and the power distributed to the terminal E is 9W, the 5 terminals are sorted according to the transmitting power from large to small, namely the terminal A, the terminal B, the terminal D, the terminal C and the terminal E schedule the terminal A to other scheduling moments, the sum of the transmitting powers of the rest terminals is 42W and is smaller than the target transmitting power, and therefore the target terminals can be determined to be the terminal B, the terminal D, the terminal C and the terminal E; the terminals with the lowest delay requirement are adjusted to other scheduling time in sequence until the sum of the transmitting powers of all the remaining terminals in the target position area is less than or equal to the target transmitting power, wherein all the remaining terminals are the target terminals, and the mode for determining the target terminals is not limited.
After adjusting other terminals in the target location area except the target terminal to other scheduling time, the number of terminals in the target location area is reduced at the target scheduling time, so the total transmission power allocated to all terminals in the target location area by the base station is also reduced, thereby reducing the signal radiation of the target location area.
By adopting the method, the target position area to be controlled and the current signal radiation of the target position area are obtained, the target transmitting power corresponding to the target position area is obtained according to the current signal radiation, and the signal radiation of the target position area is reduced according to the target transmitting power.
