[0002] In wireless communication devices that include Wi-Fi, wireless transmission power is an important technical parameter that affects key indicators such as signal coverage, quality, and throughput. At the same time, due to the connection of multiple terminals, how to improve the overall network performance by adjusting the wireless transmission power has become an increasingly important research topic.

[0003] In today's environments where access points (APs) are increasingly prevalent, most users employ the default setting of 100% static transmit power. Excessive transmit power increases the risk of co-channel interference and, in multi-terminal scenarios, the need to maintain connections and services for a few distant terminals can drag down the overall network quality. Alternatively, in some testing scenarios, such as inside a shielded enclosure or in confined spaces, the proximity of the test terminal to the AP can cause receiver saturation, affecting downlink throughput performance. Summary of the Invention

Detailed Implementation

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] First, it should be noted that a PON network includes multiple distributed ONU gateways. Each ONU gateway includes an optical network unit and an integrated wireless access point (AP). The optical network unit performs photoelectric signal conversion and PON protocol processing, while the AP is responsible for transmitting and receiving wireless signals.

[0014] In one embodiment, such as Figure 1 As shown, a power adjustment method based on a PON network and an ONU gateway is provided, including the following steps: Step S1: Obtain the first received signal strength of multiple wireless terminals connected to the first ONU gateway, and the initial transmit power of the first ONU gateway.

[0015] It should be noted that the first ONU gateway is a target optical network unit gateway deployed in the PON network, integrating wireless AP functionality, and is the sole executor of all detection, judgment, and power adjustment operations in this solution. It can independently complete local data acquisition and algorithm calculation without the need for upper-layer controller collaboration. The first received signal strength is the real-time RSSI value reported by each wireless terminal to the first ONU gateway, used to uniquely characterize the wireless signal transmission quality and distance between the wireless terminal and the first ONU gateway. A higher value indicates that the terminal is closer to the gateway and the signal quality is better. The initial transmit power is the current operating wireless radio frequency transmit power of the first ONU gateway, which is the baseline parameter for power adjustment in this solution. All subsequent upward and downward adjustments are performed based on this initial power.

[0016] In this embodiment, the first ONU gateway automatically triggers a full-network status detection according to a preset cycle (1 hour), actively collecting the real-time first received signal strength of all connected wireless terminals, and simultaneously reading its own currently effective wireless radio frequency transmission power, recording it as the initial transmission power, thus completing this round of basic data collection and providing data support for subsequent terminal type determination and power strategy matching. This step only collects terminal RSSI signal data and the gateway's own transmission power parameters, and does not collect terminal packet loss rate or neighboring gateway data at this time.

[0017] In this application, this step, through periodic and precise collection of terminal RSSI and gateway initial transmit power, can accurately characterize the basic coverage status and equipment operating parameters of the current wireless network in real time, abandoning the traditional static operation mode with fixed power. Based on the real-time dynamically collected basic data, reliable data can be provided for subsequent differentiated terminal classification and refined power adjustment, avoiding the poor adaptability problems caused by adjustment based on historical data or fixed parameters. This ensures the accuracy and real-time performance of subsequent power adjustment strategies from the source, laying a data foundation for solving network problems such as near-field signal saturation and far-field transmission stuttering.

[0018] It should be noted that the preset maximum power is the factory-set full-capacity transmit power of the first ONU gateway's wireless radio frequency, representing 100% of the baseline power. This is the maximum transmit power level for the gateway's wireless coverage and also the baseline threshold for power reduction scenarios in this solution. Before proceeding to step S2, it is necessary to determine whether the initial transmit power of the first ONU gateway is the preset maximum power. Only if the initial transmit power is the preset maximum power will the terminal type determination logic in step S2 be executed. If the initial transmit power has not reached the preset maximum power, it indicates that the gateway still has room for power increase or is operating at a non-full load. In this case, there is no need to immediately perform a power reduction operation. The current transmit power can be maintained, or regular optimization can be performed based on the actual network load, thereby avoiding unnecessary power fluctuations that could affect network stability.

[0019] Step S2: When the initial transmit power is the preset maximum power, determine the terminal type of the corresponding wireless terminal based on the strength of each first received signal.

[0020] It should be noted that the terminal type is a classification based on the terminal's RSSI signal strength and packet loss rate, including near-field terminals, mid-field terminals, and far-field terminals. This classification is used to match differentiated power adjustment strategies and achieve precise control. Near-field terminals are wireless terminals located extremely close to the first ONU gateway with extremely high received signal strength. These terminals are typically located on the inner edge of the gateway's coverage area, and their reported first received signal strength value is large, usually significantly higher than the signal threshold required for normal communication, easily causing the terminal receiver to enter the nonlinear saturation region. Mid-field terminals are wireless terminals located at a moderate distance from the gateway with received signal strength within the normal communication range. Their RSSI value is between the first and second strength thresholds, with stable signal quality and no obvious risk of saturation or attenuation. Far-field terminals are wireless terminals located far from the gateway with low received signal strength. Their RSSI value is below the third strength threshold and is often accompanied by a high packet loss rate. They are susceptible to environmental noise and multipath effects, leading to unstable data transmission. The first strength threshold is the determination threshold for near-field terminals, used to distinguish between near-field terminals at close range and mid-field terminals with normal coverage. It is the core threshold for identifying the risk of terminal receiver saturation. The second strength threshold is the determination threshold for mid-field terminals, used to distinguish between mid-field terminals with regular coverage and long-range terminals far from the gateway. It is a key indicator for defining mid- and far-field coverage areas, and the second strength threshold is lower than the first strength threshold. The third strength threshold is the determination threshold for far-field terminals, used to distinguish between far-field terminals with severe signal attenuation and long-range terminals with acceptable signal quality. It helps determine the degree of signal attenuation and connection stability risk of far-field terminals, and the third strength threshold is lower than the second strength threshold, used to define the critical point of extreme signal attenuation. The packet loss threshold is the anomaly determination threshold for long-range terminals, used to determine whether ultra-long-range wireless terminals have serious transmission anomalies that are dragging down the overall network performance.

[0021] Specifically, when the strength of the first received signal is greater than the first strength threshold, the terminal type of the corresponding wireless terminal is determined to be a near-field terminal.

[0022] It should be noted that near-field terminals, due to their extremely close proximity to the gateway, receive extremely high signal strength, often placing them at the edge of the receiver's linear operating range, which can easily lead to nonlinear distortion. Continuing to transmit at full power not only wastes energy but also exacerbates co-channel interference, causing a decline in the performance of adjacent channels. Therefore, identifying such near-field terminals is a prerequisite for implementing power reduction control. This aims to moderately reduce the transmit power, allowing the signal strength to fall back to the receiver's optimal linear operating range, thereby improving overall spectral efficiency and network throughput while ensuring connection stability.

[0023] In this embodiment, the first strength threshold is set to -35dBm. When the first received signal strength of the corresponding wireless terminal is greater than -35dBm, the corresponding wireless terminal is determined to be a near-field terminal. If it is determined that there is a near-field terminal among the wireless terminals with a first received signal strength greater than the first strength threshold of -35dBm, and the first received signal strength of all other wireless terminals is within the high-quality signal range of -40dBm to -65dBm, then a near-field terminal saturation scenario is determined to exist in the PON network. This type of near-field terminal signal power is too strong, which can easily cause terminal receiver saturation, signal-to-noise ratio degradation, and downlink throughput attenuation. This is a near-field abnormal scenario that this solution focuses on optimizing.

[0024] Furthermore, when the strength of the first received signal is less than the first strength threshold but greater than the second strength threshold, the terminal type of the corresponding wireless terminal is determined to be a mid-field terminal.

[0025] In this embodiment, the second strength threshold is set to -40dBm. When the first received signal strength of each wireless terminal is uniformly in the range of (-40dBm, -35dBm), it is determined that there are no near-field terminals and far-field terminals. The overall terminal signal quality is excellent, but there is a slight risk of receiver saturation. This is determined to be a mid-field fine-tuning scenario, which requires a slight reduction in power to avoid saturation problems while ensuring that the full coverage is not reduced.

[0026] Furthermore, when the first received signal strength is less than the second strength threshold, the packet loss rate of the wireless terminal corresponding to the first received signal strength being less than the third strength threshold is obtained. If the packet loss rate is greater than the packet loss threshold, the terminal type of the corresponding wireless terminal is determined to be a far-field terminal.

[0027] In this embodiment, the third strength threshold is set to -75dBm, and the packet loss threshold is set to 10%. If there are no near-field terminals with a first received signal strength greater than -40dBm, and the first received signal strength of most wireless terminals is in the excellent range of -40dBm to -65dBm, with only a few ultra-long-range terminals having a first received signal strength less than the third strength threshold of -75dBm, then the real-time packet loss rate of the corresponding ultra-long-range terminal is retrieved. If the packet loss rate of the corresponding ultra-long-range terminal is greater than the preset packet loss threshold of 10%, then the ultra-long-range terminal is determined to be a high-packet-loss far-field terminal. This far-field terminal has extremely poor signal and severe packet loss, which will continuously generate a large number of retransmitted packets, occupy air interface resources, and drag down the network speed of all wireless terminals in the entire network.

[0028] In this application, by precisely classifying terminals into three categories—near-field terminals, mid-field terminals, and far-field terminals—using hierarchical thresholds, a refined identification of wireless network terminal status is achieved, breaking through the coarse-grained mode of indiscriminate parameter tuning in traditional solutions. By classifying terminals for different distances and transmission states, two core network problems can be accurately identified: signal saturation and distortion in near-field terminals and high packet loss and network scrambling issues in far-field terminals. This provides precise target support for subsequent matching of differentiated and targeted power adjustment strategies, avoiding the technical pain point that single parameter tuning cannot simultaneously address near-field saturation and far-field coverage, and significantly improving the adaptability of power control.

[0029] Step S3: Determine the wireless transmission power adjustment strategy of the first ONU gateway according to the terminal type.

[0030] It should be noted that, since the signal characteristics and network impacts of different terminal types vary significantly, differentiated wireless transmission power adjustment strategies need to be developed for different terminal types.

[0031] Since the terminal types include near-field terminals, the wireless transmission power adjustment strategy also includes a near-field terminal adjustment strategy. The near-field terminal adjustment strategy is designed to address the receiver saturation problem caused by excessively strong near-field terminal signals. By accurately quantifying the degree of excessive signal strength and dynamically calculating the power reduction range, it eliminates receiver saturation distortion while avoiding coverage blind spots in the mid-field and far-field terminals due to sudden power drops, thus achieving a balance between near-field interference suppression and stable full-area coverage.

[0032] like Figure 2 As shown, the steps corresponding to determining the near-field terminal adjustment strategy in step S3 include: Step S301: Select the maximum value from each first received signal strength as the target received signal strength, and calculate the difference between the target received signal strength and the first strength threshold to obtain the signal strength difference.

[0033] It should be noted that the target received signal strength is the maximum value of the first received signal strength of all wireless terminals connected to the ONU gateway in this round of testing. It is used to quantify the degree of excessive signal strength of the near-field terminal and serves as the core calculation parameter for linear power reduction. The signal strength difference is the difference between the target received signal strength and the first strength threshold. The larger the difference, the more severe the near-field terminal signal and receiver saturation problem, and the greater the corresponding power reduction.

[0034] The signal strength difference reflects the extent to which the received signal from the near-field terminal exceeds its linear operating range, and is a key factor in determining the power reduction margin. A larger signal strength difference indicates more severe signal saturation at the near-field terminal, requiring a corresponding increase in power suppression to ensure that the adjusted transmit power accurately matches the near-field interference conditions in the current network environment.

[0035] Step S302: Calculate the difference between the preset maximum power and the signal strength difference, obtain the first power reduction range of the first ONU gateway, and determine the near-field terminal adjustment strategy as reducing the initial transmit power to the first transmit power based on the first power reduction range.

[0036] It should be noted that the first power reduction is a linear adjustment calculated directly based on the signal strength difference, designed to quickly eliminate receiver saturation distortion in near-field terminals. The first transmit power is the result of subtracting the first power reduction from the preset maximum power. This near-field terminal adjustment strategy ensures that the signal strength of the near-field terminal falls back to the linear operating range, fundamentally eliminating saturation distortion, while retaining sufficient power margin to maintain normal communication between mid-field and far-field terminals.

[0037] In this embodiment, the first power reduction magnitude can be expressed as: ; in, This indicates the magnitude of the first power reduction. This indicates the preset maximum power. The value represents the target received signal strength, and 35 represents the first strength threshold (unit: dBm). This formula shows that the first power reduction magnitude is linearly positively correlated with the degree to which the first received signal strength exceeds the first strength threshold, ensuring the predictability and stability of the adjustment process.

[0038] During this process, it is also necessary to monitor the signal quality feedback of the mid-field terminal and the far-field terminal in real time. If it is detected that the signal attenuation in the edge area is too fast or the risk of connection interruption increases due to a significant reduction in near-field power, a compensation mechanism will be triggered immediately to moderately adjust the near-field power, or optimize the beamforming parameters while maintaining the current power, so as to ensure that the communication quality of the mid-field terminal and the far-field terminal is not significantly affected.

[0039] Furthermore, the wireless transmission power adjustment strategy includes a mid-field terminal adjustment strategy. This strategy is designed for scenarios where the mid-field terminal signal strength is moderate but there is a potential risk of saturation. By introducing a preset proportional coefficient, the power reduction range is linearly scaled, which suppresses near-field interference while avoiding unnecessary excessive suppression of the mid-field terminal communication quality.

[0040] like Figure 3 As shown, the steps in step S3 corresponding to determining the midfield terminal adjustment strategy include: Step S311: Select the maximum value from each of the first received signal strengths as the target received signal strength, and calculate the difference between the target received signal strength and the first strength threshold to obtain the signal strength difference.

[0041] It should be noted that the calculation logic for the target received signal strength and the signal strength difference in step S311 is consistent with the near-field terminal adjustment strategy described above, aiming to accurately quantify the potential saturation risk faced by the near-field terminal. This difference serves as the basis for subsequent linear scaling using a preset scaling factor, providing a precise calculation basis for determining the second power reduction magnitude in step S312.

[0042] Step S312: Based on the preset maximum power, signal strength difference, and preset proportional coefficient, determine the second power reduction range of the first ONU gateway, and determine the mid-field terminal adjustment strategy as reducing the initial transmit power to the second transmit power based on the second power reduction range.

[0043] It should be noted that the preset scaling factor is a fine-tuning factor for the mid-field terminal power, used to mitigate the power reduction of the mid-field terminal, balancing saturation risk and network coverage. The second power reduction is the result of subtracting the product of the signal strength difference and the preset scaling factor from the preset maximum power, ensuring that the power reduction of the mid-field terminal is less than that of the near-field terminal. This suppresses potential saturation risks while maximizing signal coverage in the mid-field region, avoiding deterioration of the mid-field terminal's signal-to-noise ratio due to excessive adjustment.

[0044] In this embodiment, the preset scaling factor is fixed at 0.5, meaning the power reduction of the mid-field terminal is only half that of the near-field terminal. This value is based on extensive live network test data and can effectively alleviate signal saturation while maintaining coverage stability in the mid-field area to the greatest extent, ensuring that the mid-field terminal achieves the best balance between signal quality and interference suppression. The corresponding second power reduction can be expressed as: ; in, This indicates the magnitude of the second power reduction. This indicates the preset maximum power. This indicates the target received signal strength, and 35 represents the first strength threshold (unit: dBm).

[0045] Furthermore, the wireless transmission power adjustment strategy includes a far-field terminal adjustment strategy. The step of determining the far-field terminal adjustment strategy in step S3 includes: determining the third power reduction range of the first ONU gateway based on the preset maximum power and the preset power compensation value, and determining the far-field terminal adjustment strategy as reducing the initial transmission power to the third transmission power based on the third power reduction range.

[0046] It should be noted that the preset power compensation value is a fixed power reduction value for the far-field terminal, which is used to specifically reduce the invalid signal coverage of the far-field terminal and reduce air interface interference.

[0047] In this embodiment, the preset power compensation value is 5dBm, meaning the transmit power of the far-field terminal is reduced by a fixed 5dBm from the preset maximum power. This value aims to rapidly attenuate the propagation distance of far-field signals, effectively compress ineffective coverage areas, thereby significantly reducing air interface interference to adjacent cells or co-channels and improving overall spectrum reuse efficiency. The corresponding third power reduction can be expressed as: ; in, This indicates the magnitude of the power reduction. 5 indicates the preset maximum power, and 5 indicates the preset power compensation value (unit: dBm).

[0048] Furthermore, the terminal types mentioned in step S2 also include weak signal terminals, which are wireless terminals whose received signal strength is below a certain threshold and located in coverage edge areas. These terminals are typically far from the base station or obstructed by buildings, resulting in insufficient link budget and easily affected communication quality due to fluctuations.

[0049] like Figure 4 As shown, the corresponding power adjustment method also includes a process for determining weak signal terminals, specifically including the following steps: Step S51: When the initial transmit power is less than the preset maximum power, obtain the number of gateways of the second ONU gateway connected to the wireless terminal and the second received signal strength corresponding to the wireless terminal.

[0050] It should be noted that the second ONU gateway is an adjacent ONU gateway in the PON network, other than the local first ONU gateway, that can establish communication with the current wireless terminal in the surrounding environment. It is used to characterize the adjacent channel interference environment of the current wireless network. The second received signal strength is the RSSI signal strength of the surrounding second ONU gateway detected by the wireless terminal, used to quantify the intensity of external wireless interference.

[0051] In this embodiment, when the initial transmit power of the first ONU gateway does not reach the preset maximum power, all second ONU gateways that can be detected by the wireless terminal are scanned and acquired, the number of valid second ONU gateways is counted, and the second received signal strength of each second ONU gateway detected by the wireless terminal is collected.

[0052] Step S52: If the number of gateways is less than the preset number and the second received signal strength is less than the fourth strength threshold, and the corresponding first received signal strength is less than the fifth strength threshold but greater than the third strength threshold, then the terminal type of the corresponding wireless terminal is determined to be a weak signal terminal.

[0053] It should be noted that the preset quantity is a threshold for the number of neighboring gateways in a clean wireless environment, used to define the density of surrounding interfering devices. The third strength threshold is also the lowest signal threshold for weak signal terminals, representing the lower limit of the weak signal range. The fourth strength threshold is a neighboring interference judgment threshold, used to determine the strength of interference from surrounding gateways; the fourth strength threshold is greater than the third strength threshold. The fifth strength threshold is the highest signal threshold for weak signal terminals, representing the upper limit of the weak signal range; the fifth strength threshold is greater than the third strength threshold. A weak signal terminal is a moderately weak signal terminal in a low-interference wireless environment, with its own RSSI falling between the third and fifth strength thresholds, and has room for power gain optimization.

[0054] In this embodiment, the preset quantity is 3, the fourth strength threshold is -60dBm, the fifth strength threshold is -65dBm, and the third strength threshold is -75dBm. That is, the determination range of the weak signal terminal is [-75dBm, -65dBm], and the number of gateways of the second ONU gateway with neighboring cell interference is less than 3.

[0055] Furthermore, if the number of gateways for the second ONU gateway obtained from the statistics is less than the preset number of 3, and the strength of all second received signals is less than the fourth strength threshold of -60dBm, then the current environment is determined to be a low-interference, clean wireless environment. Based on this, the signal quality of the wireless terminal itself is further verified: if the strength of the first received signal corresponding to the wireless terminal is less than the fifth strength threshold of -65dBm but greater than the third strength threshold of -75dBm, then the wireless terminal is accurately determined to be a weak signal terminal. The values ​​of the fourth and fifth strength thresholds are both greater than the third strength threshold, ensuring that the weak signal range is a continuous and reasonable medium-weak signal range.

[0056] Furthermore, the wireless transmission power adjustment strategy also includes a weak signal terminal adjustment strategy. The corresponding step S3 may also include: based on the weak signal terminal, determining that the weak signal terminal adjustment strategy is to increase the initial transmission power to a preset maximum power.

[0057] In this application, the above steps, through a triple-condition judgment of "gateway power status prediction + neighboring cell interference environment verification + precise screening of the terminal's own RSSI interval," accurately identify medium-weak signal terminals in low-interference scenarios, avoiding the shortcomings of traditional solutions that do not distinguish between interference environments and blindly reduce or increase power. By limiting the fourth and fifth strength thresholds to be greater than the third strength threshold, the signal interval boundaries of weak signal terminals are strictly constrained, ensuring that the terminals do not have the risk of near-field saturation, nor do they have the problems of extremely weak networks at ultra-long distances and high packet loss that cannot be optimized. They belong to the terminal group whose communication quality can be effectively improved by increasing the transmission power. In a clean wireless environment with minimal surrounding interference, by restoring the gateway to full power operation, the wireless coverage range can be maximized and the signal-to-noise ratio and throughput of medium-weak signal terminals can be improved without generating co-channel or adjacent-channel interference or causing terminal reception saturation. This effectively compensates for some of the coverage loss caused by the aforementioned power reduction strategy, and achieves a two-way dynamic adaptive balance of reducing power to resist interference when there is high interference and increasing power to improve coverage when there is low interference, further improving the integrity and adaptability of the overall power control system.

[0058] In some embodiments, for certain wireless signal terminals that have undergone power downgrading, their current transmit power may be lower than the preset maximum power. If a fluctuation in the signal quality of the terminal or a drop in received signal strength to the weak signal range is detected at this time, the terminal type can be reassessed as a weak signal terminal, and a power recovery mechanism can be triggered to restore the current transmit power of the corresponding first ONU gateway to the preset maximum power, thereby ensuring communication continuity and service quality in the edge area. In addition, to prevent frequent power oscillations, a hysteresis comparison mechanism or time window filtering can be introduced. Power upgrading is only performed when the signal strength remains below a threshold for a set duration, thereby avoiding frequent power switching caused by instantaneous signal fluctuations and ensuring the stability of the terminal's transmit power.

[0059] In some embodiments, the aforementioned strength thresholds, such as the first strength threshold, the second strength threshold, and the third strength threshold, as well as parameters such as the preset proportional coefficient and the preset power compensation value, are not fixed but can be flexibly configured according to the actual network environment, service requirements, or operator strategies. For example, in high-density user scenarios, the preset proportional coefficient can be appropriately increased to enhance coverage in the mid-field area; while in wide-area sparse coverage scenarios, the coefficient can be appropriately decreased or the preset power compensation value can be adjusted to more aggressively suppress long-distance interference, thereby achieving global optimization of network performance. This dynamic configuration mechanism enables the power adjustment strategy to adapt to different network topologies and service load characteristics, thus maintaining high robustness and flexibility in complex and ever-changing live network environments.

[0060] In this application, the above steps achieve refined, quantitative, and adaptive closed-loop control of power adjustment by establishing a one-to-one corresponding hierarchical differentiated power regulation strategy. For the exclusive scenario of "strong near-field signal + good signal from other terminals", a full linear power reduction algorithm is adopted to accurately match the saturation level of the near-field receiver, completely solving the problems of terminal reception saturation, signal-to-noise ratio reduction, and throughput attenuation caused by excessively strong near-field signals. For the mid-field scenario where all terminals are in the critical saturation range, a 0.5 proportional coefficient is used to halve the power reduction range, taking into account the slight saturation risk and the overall wireless coverage range, and avoiding coverage holes caused by excessive power reduction. For the special scenario of "good quality terminals across the entire network, but high packet loss at a single far end", a combination strategy of fixed 5dBm power reduction + forced removal of abnormal terminals is adopted to accurately remove invalid air interface retransmissions, solving the pain point of single terminals dragging down the overall network speed that traditional solutions cannot address. For clean wireless environments with few neighboring APs and low interference, full power is actively restored to terminals with moderately weak signals to maximize long-distance coverage. This set of layered control logic is completely consistent with the original algorithm, complementing and adapting to multiple scenarios, and completely abandoning the crude defects of traditional WiFi power fixed level adjustment and single-dimensional parameter tuning.

[0061] Step S4: Adjust the initial transmission power according to the wireless transmission power adjustment strategy.

[0062] In this embodiment, after completing the terminal type identification and matching of the corresponding wireless transmission power adjustment strategy through the aforementioned steps, the first ONU gateway performs a corresponding adaptive adjustment operation on its initial transmission power according to the determined adjustment strategy: if it matches the near-field terminal adjustment strategy, the initial transmission power is reduced to the first transmission power according to the calculated first power reduction magnitude; if it matches the mid-field terminal adjustment strategy, the initial transmission power is slightly reduced to the second transmission power according to the calculated second power reduction magnitude; if it matches the far-field terminal adjustment strategy, the initial transmission power is reduced to the third transmission power according to the calculated third power reduction magnitude, and the connection of the terminal with high packet loss is forcibly disconnected when it is still online; if it matches the weak signal terminal adjustment strategy, the initial transmission power, which is lower than the preset maximum power, is directly increased to restore it to the preset maximum power. After the gateway completes this round of power adjustment, it maintains the current power stable operation and waits for a preset one-hour period before automatically restarting a new round of network status detection and power adaptive process to achieve iterative optimization.

[0063] In this application, this step translates the theoretical logic of preliminary data collection, terminal classification, and strategy determination into executable RF power control actions, forming a complete periodic closed-loop adaptive optimization system. Differentiated power scaling for different network scenarios addresses various wireless network defects: near-field and mid-field gradient linear power reduction eliminates near-field terminal receiver saturation, signal-to-noise ratio degradation, and throughput decline at the root; far-field power reduction combined with an abnormal terminal removal mechanism thoroughly cleans up invalid retransmission resources on the air interface, preventing single high-packet-loss terminals from dragging down the overall network transmission performance; and a full-power recovery strategy in low-interference environments effectively compensates for coverage loss caused by power reduction, maximizing the use of clean spectrum resources to improve communication quality for weak-signal terminals. Compared to the traditional ONU gateway's fixed static power and uniform level adjustment, this step dynamically adjusts parameters based on real network conditions, balancing multiple needs such as anti-interference, anti-saturation, speed improvement, and coverage maintenance. It requires no manual configuration intervention, significantly improving the adaptive capability and overall network stability of ONU wireless networking under PON networks.

[0064] In summary, this application discloses a power adjustment method based on a PON network and an ONU gateway, applicable to a first ONU gateway. The method includes the following steps: acquiring the first received signal strength of multiple wireless terminals connected to the first ONU gateway, and the initial transmit power of the first ONU gateway; when the initial transmit power is a preset maximum power, determining the terminal type of each wireless terminal based on its first received signal strength; determining the wireless transmit power adjustment strategy of the first ONU gateway based on the terminal type; and adjusting the initial transmit power according to the wireless transmit power adjustment strategy. This method achieves a technological leap from "static, coarse configuration" to "dynamic, precise adaptation" by finely classifying and differentially controlling the power of wireless terminals. This method not only effectively solves technical pain points such as near-field terminal signal saturation, insufficient far-field weak signal coverage, and high packet loss terminals occupying air interface resources, but also significantly improves the adaptive capability, spectrum utilization, and overall communication stability of wireless networking in a PON network environment through a periodic closed-loop iteration mechanism.
