[0001] This application relates to the field of communication technology, and in particular to a communication resource scheduling method, apparatus, computer equipment, computer-readable storage medium, and computer program product. Background Technology

[0002] For overhead transmission tower nodes that can be connected to optical fibers, the communication equipment installed is a 5th Generation Mobile Networks (5G) base station. The 5G base station can quickly and stably upload the monitoring data collected from terminals or customer premises equipment (CPE) to the core network equipment in the substation equipment room via optical fiber. For tower nodes without optical fiber, an Integrated Access and Backhaul Distributed Unit (IAB DU) or terminal equipment is installed to collect data from nearby sensors or to act as a multi-hop node to provide relay for other communication equipment to reach the 5G base station.

[0003] Because these devices all use solar panels or high-voltage induction power, the power supply is unstable, and in bad weather, they may not be able to provide enough power to transmit data back to the core network equipment in a timely and reliable manner. Summary of the Invention

[0025] Statistical analysis of the historical power generation fluctuation parameters;

[0026] The abnormal performance of the statistical communication equipment at different transmission rates when the supplied power parameters conform to the historical power generation fluctuation parameters;

[0027] Based on the aforementioned abnormal behavior, a reliability risk coefficient is determined;

[0028] The second mapping relationship is determined by associating the power generation fluctuation parameters, the transmission rate, and the reliability risk coefficient.

[0029] In one embodiment, the target transmission mode includes a first transmission mode or a second transmission mode; the first transmission mode is direct communication between the base station and the terminal, and the second transmission mode is communication between the base station and the terminal through at least one relay device; determining the target transmission path according to the service priority of the data to be transmitted includes:

Based on the current power generation, the amount of data to be transmitted, and a preset mapping relationship, a target transmission rate is determined. Since the mapping relationship is based on equipment energy consumption and photovoltaic input fluctuations, the target transmission rate corresponding to the current power generation and data amount is thus determined. Secondly, a target transmission mode is determined based on the service priority of the data to be transmitted; different transmission modes have different energy consumption. Finally, communication equipment on the power inspection line is scheduled according to the target transmission rate and target transmission mode to maintain stable power supply while reducing energy consumption and ensuring timely data transmission.

[0059] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0060] The communication resource scheduling method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, base station 104 communicates with core network device 102. Base station 104 can communicate with core network device 102 directly through the network, or it can communicate with core network device 102 through relay device 106. Base station 104, relay device 106 and core network device 102 are all connected through the network.

[0061] In one exemplary embodiment, such as Figure 2 As shown, a communication resource scheduling method is provided, which is applied to... Figure 1 Taking the power management module of a base station as an example, the explanation includes the following steps S202 to S208. Wherein:

[0062] Step S202: Obtain the current power generation and data to be transmitted sent by the photovoltaic controller.

[0063] The photovoltaic controller is a device used to manage the photovoltaic power generation system. It reports real-time photovoltaic power generation and fluctuation parameters to the base station, enabling the base station to perform joint communication and energy scheduling. The data to be transmitted is used to determine the results of power inspections.

[0064] To enable power line inspection, fixed sensors, cameras, and micro-vibration devices are installed on power poles. These devices collect real-time status data of the lines (such as temperature, icing, vibration, and bird nests), which is then transmitted back to the substation equipment room, i.e., the core network equipment, via communication equipment (base stations or IAB DUs) on the poles. Base stations are powered by solar panels and energy storage devices, while IAB DUs are powered by solar panels and energy storage devices or high-voltage induction generators. IAB devices can function similarly to 5G terminals, communicating with nearby 5G base stations to report data collected by their connected sensors; conversely, IAB devices can also receive data from terminals or nearby IAB devices, just like base stations.

[0065] The power consumption of various sensors along the inspection route is not stable and balanced. Therefore, some base stations or IAB equipment may experience low power or energy levels. These low-power devices need to minimize power consumption until the solar charging panel charges the energy storage device to the normal operating value before resuming normal operation.

[0066] Optionally, the power management module of the base station, i.e., the base station equipment, interacts with the photovoltaic controller. The base station's power management module is essentially a processor. To obtain the current power generation status of the photovoltaic system, the base station equipment sends data to the photovoltaic controller, such as... Figure 3 The power generation status request query shown includes the current power generation, such as whether the photovoltaic system is generating or not, and the power generation per unit time, for example, 100ms as one unit time. After receiving the power generation status request query, the photovoltaic controller will respond to the base station, indicating whether it is currently generating or not. If it is generating, it will carry the value of power generation per unit time (xxAh).

[0067] Since the amount of data to be transmitted usually needs to be uploaded for a period of time, the photovoltaic controller needs to interact with the base station periodically. The photovoltaic controller periodically notifies itself of its power generation per unit time so that the base station can adjust its transmission rate or schedule the upload rate of IAB relays or terminal devices in the coverage area according to the power generation.

[0068] During periods of continuous rainy weather, when the data to be transmitted cannot utilize the real-time electrical energy generated by photovoltaic panels and must instead rely on energy storage devices such as batteries: Figure 4 As shown, at the latest time when it needs to transmit data, the base station sends a power request to the photovoltaic controller. This request can include the amount of electricity needed and the start time of power consumption, informing the photovoltaic controller of the required power supply time, accurate to milliseconds. The purpose is to allow the photovoltaic controller to draw appropriate electrical energy from the energy storage battery. The request also informs the photovoltaic controller of the required output current value, enabling it to adjust the energy storage battery output to better match the power supply for the communication equipment's data transmission and reception. The photovoltaic controller responds to the power request, including the amount of electricity generated per unit time, and returns this information to the base station equipment.

[0069] Optionally, the base station equipment receives the current power generation from the photovoltaic controller, and uses the inspection data collected by various data acquisition devices along the inspection line, such as fixed sensors, cameras, and micro-vibration devices, as the data to be transmitted.

[0070] It should be noted that the current power generation is from photovoltaic devices, such as solar panels, not from energy storage devices.

[0071] Step S204: Determine the target transmission rate based on the current power generation, the amount of data to be transmitted, and the preset mapping relationship.

[0072] The mapping relationship is determined based on the energy consumption of communication equipment and fluctuations in photovoltaic input. Communication equipment includes at least one of base stations, IAB equipment, and terminals.

[0073] Optionally, the base station equipment determines the most suitable target transmission rate corresponding to the current power generation and data volume based on the current power generation, the amount of data to be transmitted, and a preset mapping relationship.

[0074] Step S206: Determine the target transmission mode based on the service priority of the data to be transmitted.

[0075] The target transmission mode can be a transmission mode in which the base station and the terminal communicate directly, or a transmission mode in which the base station and the terminal communicate through at least one relay device.

[0076] Optionally, the base station equipment determines the appropriate target transmission mode based on the service priority of the data to be transmitted.

[0077] Step S208: Schedule the communication equipment on the power inspection line based on the target transmission rate and target transmission mode.

[0078] Optionally, the base station equipment generates scheduling instructions based on the target transmission rate and target transmission mode, and schedules the communication equipment on the power inspection line according to the scheduling instructions.

[0079] In the aforementioned communication resource scheduling method, firstly, the current power generation and data to be transmitted sent by the photovoltaic controller are obtained. Based on the current power generation, the amount of data to be transmitted, and a preset mapping relationship, the target transmission rate is determined. Since the mapping relationship is determined based on equipment energy consumption and photovoltaic input fluctuations, the target transmission rate corresponding to the current power generation and data volume is thus determined. Secondly, the target transmission mode is determined based on the service priority of the data to be transmitted; different transmission modes have different energy consumption. Finally, the communication equipment on the power inspection line is scheduled according to the target transmission rate and target transmission mode, achieving stable power supply while reducing energy consumption and ensuring timely data transmission.

[0080] In one exemplary embodiment, such as Figure 5 As shown, the mapping relationship includes a first mapping relationship between the amount of data transmitted, the transmission rate, and the power consumption, and a second mapping relationship between the power generation fluctuation parameter, the transmission rate, and the reliability risk coefficient; the target transmission rate is determined based on the current power generation, the amount of data to be transmitted, and the preset mapping relationship, including steps S502 to S506. Wherein:

[0081] Step S502: Based on the current power generation, determine the estimated power consumption; based on the estimated power consumption, the amount of data to be transmitted, and the first mapping relationship, determine the candidate transmission rate required to transmit the amount of data to be transmitted.

[0082] Optionally, the base station equipment determines the total electrical energy that can be provided within the estimated transmission duration based on the current power generation (power generation per unit time) of the photovoltaic system. This total electrical energy is also the upper limit of the estimated power consumption of the communication equipment. The base station equipment, based on the total amount of data to be transmitted and a pre-generated first mapping relationship (which records the power consumption required to transmit data at different transmission rates), can obtain candidate transmission rates corresponding to the power consumption and data volume, given the known power consumption and data volume. Multiple candidate transmission rates can exist. In different situations, a candidate transmission rate is selected; for example, when power saving is required, the candidate transmission rate with the lowest power consumption per unit time is prioritized; when timeliness is critical, the candidate transmission rate with the highest power consumption per unit time is prioritized.

[0083] Step S504: Determine the current power generation fluctuation parameters based on the current power generation; determine the reliability risk coefficient based on the current power generation fluctuation parameters, candidate transmission rate, and second mapping relationship.

[0084] Optionally, the base station equipment obtains the current power generation from the photovoltaic controller and, based on the current power generation and the power generation prior to the current power generation, can determine the current power generation fluctuation parameters. These parameters include voltage drop amplitude, fluctuation duration, and the positive / negative switching time of the deviation. The deviation is the difference between the energy input from the photovoltaic system and the energy demand (usually called the load) on the power-consuming equipment side.

[0085] Furthermore, the base station equipment takes the current power generation fluctuation parameters and the obtained candidate transmission rates as inputs and queries the pre-generated second mapping relationship. This mapping relationship records the reliability risk coefficients of the communication equipment when performing transmission under different power generation fluctuation parameters and different transmission rates, such as bit error rate increment, PLL lockout probability, etc., thereby obtaining the corresponding reliability risk coefficients.

[0086] Step S506: If the reliability risk coefficient meets the preset conditions, the corresponding candidate transmission rate is determined as the target transmission rate.

[0087] Optionally, the reliability risk coefficient is compared with the reliability requirements in the service attributes of the data to be transmitted. If the reliability risk coefficient is less than or equal to the allowable threshold (i.e., the preset condition is met), the candidate transmission rate is determined as the target transmission rate; otherwise, the candidate transmission rate is reduced (e.g., reduced to the next speed level) and the aforementioned steps are returned for re-evaluation until a rate that meets the reliability requirements is found. If none of the rates are met, transmission is suspended and the photovoltaic controller is requested to improve the power supply quality.

[0088] Based on the target transmission rate and the service priority of the data to be transmitted, the base station selects one of the following transmission modes: direct communication between the base station and the terminal, and communication between the base station and the terminal through at least one relay device. The base station allocates wireless resources to the relevant communication devices, issues scheduling commands, and executes the transmission of the data to be transmitted.

[0089] In this embodiment, by simultaneously considering the constraints of photovoltaic power generation on transmission energy consumption (first mapping relationship) and the impact of power generation fluctuations on transmission reliability (second mapping relationship), a transmission rate that meets reliability requirements while maximizing energy efficiency is dynamically selected, ensuring that data transmission does not exceed the currently available electrical energy. This avoids data transmission failures due to insufficient power and data corruption or command loss due to voltage fluctuations, thereby achieving timely and high-quality return of the data to be transmitted.

[0090] In one exemplary embodiment, such as Figure 6 As shown, the method for generating the mapping relationship includes steps S602 to S606. Wherein:

[0091] Step S602: Obtain the converged communication network deployed on the power inspection line.

[0092] The communication equipment in the converged communication network includes base stations connected by optical fibers and relay equipment that does not have optical fiber connections.

[0093] Optionally, the base station equipment acquires information about the converged communication network deployed along the inspection route, such as... Figure 7 As shown, the communication equipment (including base stations and IAB equipment) on the poles along the inspection route requires overlapping coverage. Base station A is located on pole 1, and base station A can cover poles 2, 3, and 4. Base station B is also located on pole 5, which can cover poles 2, 3, and 4. Therefore, these five poles are actually jointly covered by base stations A and B. This overlapping coverage ensures that if any one base station fails, the others can still provide basic coverage, guaranteeing smooth power communication. Furthermore, 5G base stations are installed on poles with fiber optic cables, while IAB equipment is installed on poles without fiber optic cables, forming a converged communication network along the power inspection route.

[0094] The aforementioned target transmission modes include a first transmission mode or a second transmission mode. The first transmission mode involves direct communication between the base station and the terminal, while the second transmission mode involves communication between the base station and the terminal via at least one relay device. The advantage of the first transmission mode is low communication latency. Energy consumption depends on the distance between the terminal and the base station and the amount of data transmitted. If the terminal is far from the base station, the energy required to transmit the same amount of data will increase by the square of the distance. The advantage of the second transmission mode is that when the terminal reaches the IAB device, the energy consumption of each hop is almost the same, and the energy consumption for transmitting one piece of data only increases by a factor of several hops. The disadvantage is that the transmission latency increases by a factor of several hops for multiple data hops. For example… Figure 7 In the topology, the energy consumption of the terminal on pole 2 sending data to the base station on pole 1 is 1, while the energy consumption for sending data to pole 5 is 16. This increase in energy consumption is quite considerable. Therefore, for data with a longer allowable latency, choosing the second transmission mode is more energy-efficient.

[0095] Step S604: Obtain energy consumption statistics and energy supply statistics for at least one communication device on the converged communication network.

[0096] Optionally, the base station equipment may collect statistics on the energy consumption of at least one communication device on the communication network and statistics on the energy supply to power the communication device.

[0097] Furthermore, the energy consumption of base stations / IAB base stations / terminals needs to be statistically analyzed: In order to incorporate energy consumption into the scheduling algorithm, each component of the network equipment needs to statistically analyze its energy consumption under various conditions, including energy consumption, the amount of data transmitted and received, and the definition of communication distance: measurement intervals: 20ms, 40ms, 80ms, 160ms, 320ms, 640ms, 1280ms; the amount of data transmitted or received, or the data transmission / reception rate; energy consumption: Joules; the expected relationship between charging time and battery energy; discharge voltage and current; discharge time; discharge stability; and the ratio of discharge capacity lower limit, etc., to obtain the energy consumption statistics of the communication equipment.

[0098] One phenomenon in photovoltaic power supply is that when the power generated by sunlight cannot meet the needs of real-time communication equipment, the energy from the energy storage battery is dispatched in real time to power the equipment. This leads to two problems: First, dispatching the energy from the energy storage battery takes time. Although the photovoltaic equipment controls this dispatching time to the millisecond level, this dispatching occurs when the energy consumption of the electrical equipment is higher than the energy generated by sunlight, exhibiting lag. Moreover, this lag depends on the detection capability of the photovoltaic controller. Second, the stable input current and voltage of the energy storage battery also requires a small delay. The two delays mentioned above, plus the dispatching delay, have a significant impact on 5G communication, especially high-bandwidth, high-frequency millimeter-wave communication. This is because voltage and / or current fluctuations can lead to calculation errors in computing chips, read / write errors in memory, frequency drift in RF chips, clock drift, and other problems. The shorter the delay, the smaller the aforementioned errors; the longer the delay, the larger the aforementioned errors. Therefore, various parameters of the input power fluctuation need to be statistically analyzed and combined with the real-time parameters of the receiving / transmitting / computing capabilities of communication equipment, so that base stations and other equipment can change their working mode or scheduling mode in the event of power fluctuation.

[0099] Therefore, the fluctuations in input power of the statistical network base station / IAB base station / terminal include: the statistical deviation on the photovoltaic controller side, the time it takes for the deviation to turn from positive to negative, the real-time photovoltaic power generation, and the parameters of external input power and power demand of various modules within the communication equipment. A deviation greater than 0 indicates that power generation exceeds the equipment's demand, while a deviation less than 0 indicates that power generation is lower than the equipment's demand.

[0100] Communication equipment includes base stations, and the modules inside the base station, such as... Figure 8 As shown, the core communication module includes a baseband protocol stack processing module, a power amplifier and RF module, and an antenna module. It also includes peripheral modules for operation and maintenance, power management, and data storage. The power management module is connected to the photovoltaic controller. The core communication module is highly sensitive to energy input fluctuations and has high energy consumption. Therefore, it needs to include functions for measuring and reporting input voltage, current, power consumption, and duration. The core communication module collects and reports energy-related parameters for each physical device or software module (modules with high computational load and high usage frequency) to the power management module. From this extensive statistical data, the impact of insufficient energy supply or drastic voltage and current fluctuations on the transmission / reception / storage errors or data rates of the communication is analyzed.

[0101] Step S606: Determine the first mapping relationship based on energy consumption statistics; determine the second mapping relationship based on energy supply statistics.

[0102] The first mapping relationship describes the energy consumption values ​​corresponding to the amount of data sent or received by the statistical communication equipment and the transmission rate within different measurement intervals. The second mapping relationship describes whether any anomalies occur if transmission is carried out at a certain rate / path under the current power supply fluctuations.

[0103] Optionally, the base station equipment analyzes statistical data on energy consumption, such as the amount of data transmitted or received, or the data transmission and reception rate; energy consumption in Joules; the relationship between the expected charging time and battery energy; the voltage and current of discharge, the discharge duration, the stability of discharge, and the lower limit ratio of capacity, to determine a first mapping relationship. The base station equipment also analyzes statistical data on energy supply, such as the statistical deviation on the photovoltaic controller side, the time it takes for the deviation to turn from positive to negative, real-time photovoltaic power generation, and parameters of external input power and power demand of various modules within the communication equipment, to determine a second mapping relationship.

[0104] In this embodiment, by establishing a first mapping relationship and a second mapping relationship, the most suitable transmission rate and transmission model can be determined when transmitting data, so as to maintain stable power while reducing energy consumption and timely transmitting data.

[0105] In one exemplary embodiment, such as Figure 9 As shown, the energy consumption statistics include historical data volume, historical transmission rate, historical transmission duration, and historical transmission distance; based on the energy consumption statistics, a first mapping relationship is determined, including steps S902 to S904. Wherein:

[0106] Step S902: Statistically analyze the historical data volume, historical transmission rate, and historical transmission duration of the communication equipment within different measurement intervals to determine the energy consumption value.

[0107] The measurement interval is preset to a fixed value from 20ms, 40ms, 80ms, 160ms, 320ms, 640ms, and 1280ms, for example, 80ms.

[0108] Optionally, within each measurement interval, the historical operating voltage (mV) and historical operating current (mA) are collected by the power management module of the communication equipment to calculate the energy consumption value (joules) for that interval. Energy consumption value = voltage × current × measurement interval duration. Simultaneously, the historical data volume (Kbytes) transmitted or received within that interval and the corresponding historical transmission rate (Mbps) are recorded. The measurement interval, historical data volume, historical transmission rate, operating duration, and energy consumption value are stored as a single statistical record. The communication distance corresponding to this transmission can also be recorded for subsequent grouping and statistical analysis by distance.

[0109] Step S904: Associate the energy consumption value with the corresponding historical data volume and historical transmission rate to determine the first mapping relationship.

[0110] Optionally, the records are grouped according to transmission rate and / or transmission distance. For each group, the energy consumption per unit of data is calculated as energy consumption value / data volume (joules / kbyte or joules / mbyte). Then, the average or median energy consumption per unit of data within each group is calculated, forming a first mapping relationship between different transmission rates and / or different transmission distances and energy consumption per unit of data. This mapping relationship can be stored in tabular form, including at least the following: transmission distance, transmission rate, transmission duration, and energy consumption per unit of data (or total energy consumption for a given data volume). This first mapping relationship is used for subsequent scheduling to quickly estimate the total energy consumption at different transmission rates based on the data volume to be transmitted and historical transmission rates.

[0111] Energy supply statistics include historical power generation fluctuation parameters and power supply parameters; based on the energy supply statistics, a second mapping relationship is determined, including steps S906 to S910. Wherein:

[0112] Step S906: Statistically analyze historical power generation fluctuation parameters; and statistically analyze the abnormal performance of communication equipment at different transmission rates when the power supply parameters conform to the historical power generation fluctuation parameters.

[0113] Among them, historical power generation fluctuation parameters include deviation, time when the deviation changes from positive to negative or from negative to positive, real-time photovoltaic power generation V, and voltage drop amplitude, fluctuation duration, voltage / current change rate, etc. extracted from these parameters.

[0114] Optionally, the base station equipment monitors the fluctuation characteristics of external input power and the operating status of its internal modules (baseband protocol stack, power amplifier RF, antenna, power management, and data storage). When an abnormal event occurs (such as baseband calculation verification error, memory CRC error, RF PLL lockout, clock drift exceeding the threshold, or increased data retransmission requests), it records the most recent fluctuation parameter before the abnormal event (e.g., a voltage drop of 10% lasting 150 microseconds) and the transmission rate (Mbps) used by the communication equipment at that time. Each abnormal event is associated with the corresponding fluctuation parameter and transmission rate to form a statistical sample. For different transmission rates, a sufficient number of samples are accumulated to eliminate randomness. The frequency of abnormal events is statistically analyzed for each group (fluctuation parameter range, transmission rate range). For example, the probability of a bit error rate increment exceeding 0.1% under the conditions of "voltage drop amplitude of 5%~10%", "duration of 100~200 microseconds", and "transmission rate of 20~50Mbps" is statistically analyzed.

[0115] Step S908: Determine the reliability risk coefficient based on abnormal behavior.

[0116] The abnormal behavior can be at least one of the following: bit error rate increment (percentage), PLL lockout probability (percentage), memory error rate, and clock drift (ppm).

[0117] Optionally, the base station equipment obtains a weighted risk score, also known as a reliability risk coefficient, by weighting and combining at least one of the following: bit error rate increment (percentage), PLL lockout probability (percentage), memory error rate, and clock drift (ppm).

[0118] Step S910: Associate the power generation fluctuation parameters, transmission rate, and reliability risk coefficient to determine the second mapping relationship.

[0119] Optionally, the base station equipment can correlate the reliability risk coefficient with the corresponding power generation fluctuation parameters and transmission rate to obtain a second mapping relationship, which can be stored in tabular form.

[0120] In practical applications, the energy consumption of communication, data acquisition, and large-scale data preprocessing in different scenarios of the communication and sensing converged network, as well as energy supply statistics, are used to establish a first mapping relationship and a second mapping relationship. During the data transmission process, the first and second mapping relationships are used to allocate and schedule communication resources. Ultimately, the converged communication network can be used to operate autonomously without human intervention, and the equipment can operate for 5 years without force majeure damage.

[0121] In this embodiment, by establishing the first and second mapping relationships, the base station can predict the transmission reliability risks at different rates during scheduling, providing a basis for dynamically selecting safe and efficient transmission strategies.

[0122] In an exemplary embodiment, determining the target transmission path based on the service priority of the data to be transmitted includes: when the service priority is a first priority, determining a first transmission mode as the target transmission mode; when the service priority is a second priority other than the first priority, determining a second transmission mode as the target transmission mode.

[0123] The target transmission mode includes either a first transmission mode or a second transmission mode; the first transmission mode is direct communication between the base station and the terminal, while the second transmission mode is communication between the base station and the terminal through at least one relay device. The first priority category has a higher priority level than the second priority category.

[0124] Optionally, when the service priority is Class 1, the base station equipment determines the first transmission mode as the target transmission mode, that is, the mode of direct communication between the base station and the terminal is taken as the target transmission mode. When the service priority is Class 2 (other than Class 1), the mode of communication between the base station and the terminal through at least one relay device is determined as the target transmission mode.

[0125] Furthermore, such as Figure 10 As shown. The first priority category of data to be transmitted is high-priority data. High-priority data, such as operational instructions, has high latency requirements; therefore, direct communication between the base station and the terminal is chosen. The second priority category includes medium-high priority and low priority. Since medium-high priority and low-priority data are not critical for latency, a balance needs to be struck between transmission efficiency and energy consumption. To ensure the normal operation of the inspection and monitoring services, a low-energy mode is used for transmission; therefore, communication between the base station and the terminal is chosen through at least one relay device.

[0126] In this embodiment, by determining the corresponding transmission mode according to the service type, it is possible to achieve low power consumption while ensuring timely upload.

[0127] In one exemplary embodiment, such as Figure 11 As shown, the second priority category includes a first priority and a second priority; the first priority has a higher priority level than the second priority; the method also includes steps S1102 to S1106. Wherein:

[0128] Step S1102: When the current power generation is lower than the power generation threshold and the service priority is the second priority, power is supplied to the base station, terminal and relay equipment in the second transmission mode through the power in the energy storage device or by waiting until the power generation threshold is higher than or equal to the power generation threshold.

[0129] Among them, the second priority is as follows Figure 10 The low priority in the data transmission is the data to be transmitted, which is the daily monitoring data.

[0130] Since it's a photovoltaic (PV) power generation system, it's best to transmit the electricity generated directly from the PV system as soon as possible, rather than at night or on cloudy or rainy days when the PV panels cannot generate electricity. This method of utilizing PV energy during the day avoids the step of first storing the generated electricity in an energy storage battery and then releasing it from the battery, reducing energy loss caused by the charging and discharging process.

[0131] The upload rate of daily monitoring data is typically a minimum guaranteed rate Gbr within a certain range, with the maximum rate being the maximum allowed rate MaxMidRate for low to medium priority levels as defined by the network system. The frequency of daily monitoring data upload is F-jk, assumed to be at least once a day, selected during periods of sufficient sunlight. Therefore, communication between the communication base station and the photovoltaic (PV) power controller is required. The base station obtains the status and power generation of the PV controller. Once the electrical energy generated by the PV is sufficient to meet the aforementioned Gbr transmission rate for daily monitoring data upload, the base station can upload the daily monitoring data. The base station selects a transmission rate appropriate to the power generation for the monitoring data from the previous transmission up to the current time.

[0132] If the current power generation is below the power generation threshold, meaning the current power generation cannot meet the upload speed, then the base station, terminal, and relay equipment in the second transmission mode will be powered by the energy stored in the energy storage device or by waiting until the power generation reaches or exceeds the power generation threshold. Waiting until the power generation reaches or exceeds the power generation threshold means waiting for photovoltaic power generation to reach the threshold.

[0133] Step S1104: When the current power generation is lower than the power generation threshold and the service priority is the first priority, the power in the energy storage device is used to power the base station, terminal and relay equipment in the second transmission mode.

[0134] Among them, the first priority is as follows Figure 10 High-priority alerts, such as alarm messages, still have a certain degree of urgency and therefore need to be reported immediately. Regardless of whether the photovoltaic system is generating power or in any other state, the photovoltaic controller needs to provide power immediately.

[0135] Optionally, if the base station / IAB device is already transmitting data with second-priority priority, the base station will prioritize uploading data with first-priority priority. Since the base station has already obtained the real-time power generation through message interaction with the photovoltaic controller, it can prioritize allocating the transmission volume corresponding to this real-time power generation to the transmission of alarm information.

[0136] Optionally, since the data to be transmitted with the first priority needs to be uploaded immediately, when the current power generation is lower than the power generation threshold and the service priority is the first priority, the power in the energy storage device is used to power the base station, terminal and relay equipment in the second transmission mode.

[0137] Step S1106: When the current power generation is lower than the power generation threshold and the service priority is the first priority, the base station and terminal in the first transmission mode are powered by the power in the energy storage device.

[0138] The first priority data to be transmitted is also known as high-priority data. High-priority data has high latency requirements, such as operational commands. Regardless of whether photovoltaic power generation is in progress, the photovoltaic controller needs to immediately supply power to the base station and terminal in the first transmission mode using energy from the energy storage device. If other services are communicating at this time, and the photovoltaic system's power is low, the base station or IAB equipment needs to stop other service communication transmissions. In this case, the photovoltaic controller needs to exchange real-time power generation or remaining battery power with the base station / IAB equipment.

[0139] In this embodiment, by assigning different power supply methods to different service priorities, energy consumption can be reduced while timely uploading can be achieved.
