Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to a power supply method and device, a target relay node and a host node. BACKGROUND

[0002] In the 5th Generation Mobile Communication (5G) New Radio (NR) technology, in order to solve the problem of insufficient deployment of wired transmission networks when access points are densely deployed, an integrated access backhaul (IAB) system is introduced. When there is no wired transmission network, an IAB node accesses a parent IAB node based on a wireless backhaul link. The IAB node includes a distributed unit (DU) functional part and a mobile termination (MT) functional part; the IAB node can rely on its own MT to find a parent IAB node and establish a wireless connection with the DU of the parent IAB node, i.e. a backhaul link. After an IAB node establishes a complete backhaul link, the IAB node turns on its DU function, and the DU can provide wireless access services for UEs. An integrated access backhaul loop includes a donor IAB node, and the donor IAB node is directly connected to a wired transmission network.

[0003] In the prior art, although the IAB node does not need to deploy a transmission cable, each IAB node still needs stable power supply. However, when the IAB system is deployed in a mountainous area or a sparsely populated area, the power transmission network may be far away from the IAB node, and the cost of constructing a power supply line for the IAB node is also high; or when the IAB system is deployed in an urban area, the IAB nodes are dense, and there is no nearby power supply that can be used, and the cost of burying the power line is high. In these scenarios, solar energy / wind energy can be used to provide power for the IAB node. For example, a photovoltaic panel is used to convert solar energy into electrical energy and store it in an energy storage battery, and then the energy storage battery provides power for the IAB node.

[0044] This application provides a power supply method applicable to a target relay node powered by renewable energy. The method involves the target relay node receiving a first configuration message for adjusting to a target operating state, or a second configuration message carrying target conditions and the target operating state. Upon receiving the first configuration message, the target relay node adjusts to the target operating state to change its power consumption. Alternatively, upon receiving the second configuration message and when its power supply information meets the target conditions, the target relay node actively adjusts to the target operating state to change its power consumption, thereby improving the endurance of the target relay node powered by renewable energy and ensuring its ability to continuously provide relay transmission services even when renewable energy supply is limited.

[0045] Figure 2 This is one of the flowcharts illustrating the power supply method provided in this application embodiment. The method is applied to a target relay node, such as... Figure 2 As shown, the method includes the following steps:

[0046] Step 201: Receive a first configuration message; wherein the first configuration message is used to configure the target relay node to adjust to a target operating state; the target relay node is powered by renewable energy; the target operating state includes a power-saving state or a normal state; the power consumption of the target relay node in the power-saving state is less than the power consumption of the target relay node in the normal state;

[0047] Alternatively, a second configuration message may be received; wherein the second configuration message carries a target condition and the target operating state; the second configuration message is used to configure the target relay node to adjust to the target operating state when the power supply information of the target relay node meets the target condition.

[0048] Optionally, embodiments of this application can be applied to mobile communication system scenarios employing relay technology, where renewable energy sources are used to power some or all of the relay nodes; the renewable energy sources include, but are not limited to, at least one of the following: solar energy, wind energy, hydropower, biomass energy, tidal energy, and geothermal energy. The target relay nodes mentioned in the embodiments of this application include, but are not limited to, at least one of the following: IAB nodes, Reconfigurable Intelligent Surface (RIS), repeaters, and sidelink relay UEs.

[0049] Optionally, there can be one or more target conditions, each corresponding to a specific target operating state. Target operating states can include: power-saving state or normal state; the power consumption of the target relay node in power-saving state is less than that in normal state. It should be noted that configuring a target relay node to power-saving state means configuring it to switch from normal state to power-saving state; configuring a target relay node to normal state means configuring it to switch from power-saving state to normal state.

[0050] Optionally, the target operating state may include target operating parameters; wherein the target operating parameters include at least one of the following: uplink transmission power, downlink transmission power, operating time period, inactive time period, operating frequency bandwidth, and transmission cycle of the synchronization signal and broadcast physical channel block (SSB); wherein the operating time period represents the time period during which the target relay node provides relay transmission services; and the inactive time period represents the time period during which the target relay node stops providing relay transmission services. It should be noted that when the target relay node is in a power-saving state, the target relay node operates according to a power-saving state operating cycle, and one power-saving state operating cycle includes one operating time period and one inactive time period.

[0051] Taking a 5G NR system employing IAB technology as an example, the target relay node is the target IAB node. The target operating parameters of the target IAB node include at least one of the following: the maximum uplink transmission power of the target IAB node's MT (Mean Transmission Power), the maximum downlink transmission power of the target IAB node's DU (Dedicated Unit), the operating time period of the target IAB node, the inactive time period of the target IAB node, the operating frequency bandwidth of the target IAB node, and the transmission period of the target IAB node's SSB (Sends to Branches). Wherein, the operating time period of the target IAB node represents the time period during which the target IAB node provides relay transmission services; the inactive time period of the target IAB node represents the time period during which the target IAB node stops providing relay transmission services. It should be noted that the operating time period of the target IAB node can include at least one of the following time periods: the time period during which the target IAB node provides relay transmission services; the time period during which the target IAB node's DU (Dedicated Unit) provides relay transmission services; and the time period during which the target IAB node's MT (Mean Transmission Power) provides relay transmission services.

[0052] Optionally, the power supply information of the target relay node includes at least one of the following information of the renewable energy conversion device supplying power to the target relay node: the remaining charge value of the energy storage battery, the capacity of the energy storage battery, the percentage of the remaining charge of the energy storage battery, the charging power of the energy storage battery, the output power of the energy storage battery, the change in the remaining charge value of the energy storage battery, and the rate of change of the remaining charge value of the energy storage battery; wherein, the energy storage battery is used to store the electrical energy converted by the renewable energy conversion device. It should be noted that the charging power of the energy storage battery can be equivalent to the output power of the electrical energy converted by the renewable energy conversion device. Taking a renewable energy conversion device including a solar panel as an example, the output power of the solar panel is the charging power of the energy storage battery. The change in the remaining charge value of the energy storage battery can be determined by the difference between the charging power and the output power of the energy storage battery; the rate of change of the remaining charge value of the energy storage battery indicates how fast the remaining charge value of the energy storage battery changes, and can be determined by the rate of change of the remaining charge value of the energy storage battery with respect to time.

[0053] Optionally, to address the risk of power shortages or even battery depletion due to insufficient sunlight in existing technologies using solar energy and energy storage batteries, which could lead to IAB node shutdown and interruption of relay transmission services, this application embodiment targets mobile communication system scenarios where renewable energy is used to power some or all relay nodes, and the host node or operation and maintenance management (Operation Administration) The OAM (Optical and Maintenance) server sends a first configuration message to the target relay node to directly configure the target relay node to enter or exit a power-saving state. Upon receiving the first configuration message, the target relay node enters or exits the power-saving state to change its power consumption. Alternatively, the host node or OAM server does not directly configure the target relay node to adjust to the target operating state, but instead sends a second configuration message to the target relay node, configuring only the target conditions for the target relay node to enter or exit the power-saving state. Upon receiving the second configuration message, the target relay node actively enters or exits the power-saving state if the power supply information meets the target conditions, thereby changing its power consumption. This embodiment overcomes the risk of power shortages or even battery depletion due to insufficient sunlight in the use of solar energy and energy storage batteries, which can lead to IAB node shutdown and interruption of relay transmission services.

[0054] The power supply method provided in this application embodiment involves a target relay node receiving a first configuration message for configuring the target relay node to adjust to a target operating state, or a second configuration message carrying target conditions and a target operating state. Upon receiving the first configuration message, the target relay node adjusts to the target operating state to change its power consumption. Alternatively, upon receiving the second configuration message and when the power supply information of the target relay node meets the target conditions, the target relay node actively adjusts to the target operating state to change its power consumption. This improves the endurance of the target relay node powered by renewable energy and ensures its ability to continuously provide relay transmission services when renewable energy supply is limited.

[0055] Optionally, the host node or OAM server can configure the target relay node to send a power supply status report by sending a third configuration message to the target relay node; wherein the third configuration message is used to configure the target relay node to send a power supply status report. The target relay node receives the third configuration message; in response to the third configuration message, the target relay node sends its own power supply status report; wherein the power supply status report is used to report the power supply information of the target relay node.

[0056] Optionally, the host node or OAM server sends a third configuration message to the target relay node. Upon receiving the third configuration message, the target relay node, in response, sends a power supply status report to the host node or OAM server. After receiving the power supply status report, the host node or OAM server obtains the power supply information of the target relay node. Based on this information, if it is necessary to change the power consumption of the target relay node, the host node or OAM server sends a first configuration message to the target relay node to configure it to adjust to a target operating state, thereby changing the power consumption of the target relay node.

[0057] Optionally, the target relay node may send a power supply status report at at least one of the following times:

[0058] Method 1: Periodically send reports on the power supply status.

[0059] For example, a timer can be used to keep track of power supply status. Each time the timer expires, a power supply status report is generated and then sent. After the power supply status report is sent, the timer restarts.

[0060] Method 2: If the power supply information of the target relay node meets the target conditions, send a power supply status report.

[0061] Taking power supply information, including the remaining percentage of energy storage batteries, as an example, one or more trigger thresholds can be set, such as defining four trigger thresholds: 30%, 50%, 80%, and 100%. When the remaining percentage of energy storage batteries drops below a certain threshold or rises above a certain threshold, an operation to generate a power supply status report is initiated. To avoid repeated generation and sending of power supply status reports due to fluctuations in the remaining battery power, a prohibit timer can be started after each power supply status report is sent. During the operation of the prohibit timer, the generation and sending of power supply status reports are prohibited.

[0062] Optionally, after receiving the first configuration message, the target relay node adjusts itself to the target running state in response to the first configuration message.

[0063] Optionally, the host node or OAM server sends a first configuration message to the target relay node. The first configuration message is used to configure the target relay node to adjust to the target operating state. After receiving the first configuration message, the target relay node can adjust to the target operating state to change the power consumption of the target relay node.

[0064] Optionally, the target relay node can actively enter or exit a power-saving state. For example, after receiving the second configuration message, in response to the second configuration message, if the power supply information of the target relay node meets the target conditions, the target relay node will adjust itself to the target operating state.

[0065] Optionally, the host node or OAM server sends a second configuration message to the target relay node, the second configuration message carrying the target conditions and the target operating status. After receiving the second configuration message, the target relay node can actively enter or exit the power-saving state if the power supply information meets the target conditions, thereby changing the power consumption of the target relay node.

[0066] Optionally, in response to the second configuration message sent by the host node, if the power supply information of the target relay node meets the target conditions, the target relay node adjusts itself to the target operating state and then sends operating information to the host node; wherein, the operating information is used to indicate the target operating state of the target relay node. After receiving the operating information, the host node can promptly know the target operating state of the target relay node, improving the efficiency of service management and resource allocation.

[0067] Optionally, in response to the second configuration message sent by the OAM server, if the power supply information of the target relay node meets the target conditions, the target relay node adjusts itself to the target operating state and then sends the operating information to at least one of the following devices: the OAM server, the host node, the parent relay node, and the child relay node. For example, after receiving the operating information, the host node can promptly learn about the target operating state of the target relay node, improving the efficiency of service management and resource allocation. The parent and child relay nodes, upon receiving the operating information, can promptly learn about the target operating state of the target relay node and adjust their time-frequency resource configurations based on the target operating state to ensure service quality.

[0068] Optionally, the operational information can be carried in the Backhaul Adaptation Protocol (BAP) control protocol data unit (PDU) or the Medium Access Control (MAC) control element (CE).

[0069] Optionally, after establishing a backhaul link, the target relay node can proactively report to the host node or OAM server that it is powered by renewable energy. For example, the target relay node proactively sends a first report to the host node or OAM server, indicating that the target relay node is powered by renewable energy; upon receiving the first report, the host node or OAM server learns that the target relay node is powered by renewable energy.

[0070] Optionally, when the target relay node is an access IAB node, the DU of the access IAB node can send the first report to the CU of the host IAB node via an F1 Application Protocol (F1-AP) message; or, the MT of the access IAB node can send the first report to the CU of the host IAB node via a Radio Resource Control (RRC) message. Optionally, the access IAB node sends the first report to the CU of the host IAB node during random access.

[0071] Optionally, after establishing a backhaul link, the target relay node, in addition to proactively reporting to the host node or OAM server that it is powered by renewable energy, may also report the equipment information of the renewable energy conversion device powering the target relay node to the host node or OAM server. This equipment information includes at least one of the following: the electrical power output of the renewable energy conversion device, the capacity of the energy storage battery, and the output power of the energy storage battery. The energy storage battery is used to store the electrical energy converted by the renewable energy conversion device.

[0072] Figure 3 This is a second flowchart illustrating the power supply method provided in this application embodiment. This method is applied to a target relay node, such as... Figure 3 As shown, the method includes the following steps:

[0073] Step 301: Receive a third configuration message; wherein the third configuration message is used to configure the target relay node to send a power supply status report (Battery sustainability report); the target relay node is powered by renewable energy.

[0074] Step 302: In response to the third configuration message, send a power supply status report of the target relay node; wherein the power supply status report is used to report the power supply information of the target relay node;

[0075] Step 303: Receive a first configuration message; wherein the first configuration message is used to configure the target relay node to adjust to a target operating state; the target operating state includes a power-saving state or a normal state; the power consumption of the target relay node in the power-saving state is less than the power consumption of the target relay node in the normal state.

[0076] It should be noted that the explanation and interpretation of step 303 can refer to step 201 above, and the same technical effect can be achieved. To avoid repetition, it will not be repeated here.

[0077] Optionally, the host node or OAM server sends a third configuration message to the target relay node to configure the target relay node to send a power supply status report. Upon receiving the third configuration message, the target relay node, in response, sends its own power supply status report to the host node or OAM server. After receiving the power supply status report, the host node or OAM server obtains the target relay node's power supply information. Based on this information, if it is necessary to change the target relay node's power consumption, the host node or OAM server sends a first configuration message to the target relay node to configure it to adjust to a target operating state, thereby changing the target relay node's power consumption.

[0078] The power supply method provided in this application embodiment involves the target relay node responding to a third configuration message by sending a power supply status report of the target relay node to the host node or OAM server. Then, it receives a first configuration message for configuring the target relay node to adjust to the target operating state, thereby adjusting the target relay node to the target operating state to change the power consumption of the target relay node. This improves the endurance of the target relay node powered by renewable energy and ensures that the target relay node can continuously provide relay transmission services when renewable energy power supply is limited.

[0080] Step 401: Receive a first configuration message; wherein the first configuration message is used to configure the target relay node to adjust to a target operating state; the target relay node is powered by renewable energy; the target operating state includes a power-saving state or a normal state; the power consumption of the target relay node in the power-saving state is less than the power consumption of the target relay node in the normal state;

[0081] Step 402: In response to the first configuration message, adjust the target relay node to the target running state.

[0082] It should be noted that the explanation and interpretation of step 401 can refer to step 201 above, and the same technical effect can be achieved. To avoid repetition, it will not be repeated here.

[0083] Optionally, the host node or OAM server sends a first configuration message to the target relay node, which is used to configure the target relay node to adjust to the target running state.

[0084] After receiving the first configuration message, the target relay node can adjust to the target operating state to change the power consumption of the target relay node.

[0085] The power supply method provided in this application embodiment receives a first configuration message for configuring the target relay node to adjust to a target operating state. Upon receiving the first configuration message, the target relay node adjusts to the target operating state to change the power consumption of the target relay node, thereby improving the endurance of the target relay node powered by renewable energy and ensuring the ability of the target relay node to continuously provide relay transmission services when renewable energy power supply is limited.

[0086] Figure 5This is the fourth flowchart illustrating the power supply method provided in this application embodiment. This method is applied to a target relay node, such as... Figure 5 As shown, the method includes the following steps:

[0087] Step 501: Receive a second configuration message; wherein the second configuration message carries target conditions and the target operating state; the second configuration message is used to configure the target relay node to adjust to the target operating state when the power supply information of the target relay node meets the target conditions;

[0088] Step 502: In response to the second configuration message, if the power supply information of the target relay node meets the target conditions, adjust the target relay node to the target operating state.

[0089] It should be noted that the explanation and interpretation of step 501 can refer to step 201 above, and the same technical effect can be achieved. To avoid repetition, it will not be repeated here.

[0090] Optionally, the host node or OAM server sends a second configuration message to the target relay node, the second configuration message carrying the target conditions and the target operating status.

[0091] After receiving the second configuration message, the target relay node can actively enter or exit the power saving state to change the power consumption of the target relay node if the power supply information meets the target conditions.

[0092] Optionally, in response to the second configuration message sent by the host node, if the power supply information of the target relay node meets the target conditions, the target relay node adjusts itself to the target operating state and then sends operating information to the host node; wherein, the operating information is used to indicate the target operating state of the target relay node. After receiving the operating information, the host node can promptly know the target operating state of the target relay node, improving the efficiency of service management and resource allocation.

[0093] Optionally, in response to the second configuration message sent by the OAM server, if the power supply information of the target relay node meets the target conditions, the target relay node adjusts itself to the target operating state and then sends the operating information to at least one of the following devices: the OAM server, the host node, the parent relay node, and the child relay node. For example, after receiving the operating information, the host node can promptly learn about the target operating state of the target relay node, improving the efficiency of service management and resource allocation. The parent and child relay nodes, upon receiving the operating information, can promptly learn about the target operating state of the target relay node and adjust their time-frequency resource configurations based on the target operating state to ensure service quality.

[0094] The power supply method provided in this application embodiment actively adjusts the target relay node to the target operating state when the target relay node receives the second configuration message and the power supply information of the target relay node meets the target conditions, thereby changing the power consumption of the target relay node and improving the endurance of the target relay node powered by renewable energy. This ensures that the target relay node can continuously provide relay transmission services when renewable energy power supply is limited.

[0095] Figure 6 This is the fifth flowchart illustrating the power supply method provided in this application embodiment. This method is applied to a host node or OAM server, such as... Figure 6 As shown, the method includes the following steps:

[0096] Step 601: If the power supply information of the target relay node meets the target conditions, send a first configuration message to the target relay node; wherein, the first configuration message is used to configure the target relay node to adjust to the target operating state; the target relay node is powered by renewable energy; the target operating state includes a power-saving state or a normal state; the power consumption of the target relay node in the power-saving state is less than the power consumption of the target relay node in the normal state;

[0097] Alternatively, a second configuration message may be sent to the target relay node; wherein the second configuration message carries the target conditions and the target operating state; the second configuration message is used to configure the target relay node to adjust to the target operating state when the power supply information of the target relay node meets the target conditions.

[0098] Optionally, embodiments of this application can be applied to mobile communication system scenarios employing relay technology, where renewable energy sources are used to power some or all of the relay nodes; the renewable energy sources include, but are not limited to, at least one of the following: solar energy, wind energy, hydropower, biomass energy, tidal energy, and geothermal energy. The host nodes mentioned in embodiments of this application include, but are not limited to, at least one of the following: IAB node, active RIS, repeater, and sidelink relay UE.

[0099] It should be noted that the limitations, explanations and interpretations of the target conditions, target operating status and power supply information can be found in step 201 above. To avoid repetition, they will not be repeated here.

[0100] Optionally, when the power supply information of the target relay node meets the target conditions, the host node or OAM server sends a first configuration message to the target relay node. The first configuration message configures the target relay node to adjust to the target operating state. After receiving the first configuration message, the target relay node adjusts to the target operating state to change its power consumption. Alternatively, the host node or OAM server does not directly configure the target relay node to adjust to the target operating state, but instead sends a second configuration message to the target relay node. The second configuration message carries the target conditions and the target operating state, configuring only the target conditions for the target relay node to adjust to the target operating state. After receiving the second configuration message, if the power supply information meets the target conditions, the target relay node actively adjusts to the target operating state to change its power consumption. This overcomes the risk of power shortages or even battery depletion due to insufficient sunlight in the use of solar energy and energy storage batteries, which could lead to the shutdown of the IAB node and interruption of relay transmission services.

[0101] The power supply method provided in this application embodiment involves the host node or OAM server sending a first configuration message to the target relay node when the power supply information of the target relay node meets the target conditions. This configuration message configures the target relay node to adjust to the target operating state, thereby changing the power consumption of the target relay node. Alternatively, the host node or OAM server does not directly configure the target relay node to adjust to the target operating state. Instead, it sends a second configuration message carrying the target conditions and the target operating state to the target relay node, enabling the target relay node to actively adjust to the target operating state when the power supply information meets the target conditions. This changes the power consumption of the target relay node, thereby improving the endurance of the target relay node powered by renewable energy and ensuring the ability of the target relay node to continuously provide relay transmission services when renewable energy power supply is limited.

[0102] Optionally, after establishing a backhaul link, the target relay node proactively reports to the host node or OAM server that it is powered by renewable energy. For example, the target relay node proactively sends a first report to the host node or OAM server, the first report indicating that the target relay node is powered by renewable energy; after receiving the first report, the host node or OAM server knows that the target relay node is powered by renewable energy.

[0103] Optionally, in this embodiment of the application, the method by which the host node or OAM server obtains the power supply information of the target relay node may include: the host node or OAM server sending a third configuration message to the target relay node; wherein, the third configuration message is used to configure the target relay node to send a power supply status report; the power supply status report is used to report the power supply information of the target relay node. After receiving the third configuration message sent by the host node or OAM server, the target relay node sends the power supply status report to the host node or OAM server. Then, upon receiving the power supply status report sent by the target relay node, if the power supply information meets the target conditions, the host node or OAM server sends a first configuration message to the target relay node to configure the target relay node to adjust to the target operating state, thereby changing the power consumption of the target relay node.

[0104] Optionally, when the host node sends a second configuration message to the target relay node, the target relay node, in response to the second configuration message, adjusts itself to the target operating state if its power supply information meets the target conditions. Then, the target relay node can send operating information to the host node, the operating information indicating the target operating state. Upon receiving the operating information, the host node can promptly ascertain the target operating state of the target relay node, improving the efficiency of service management and resource allocation.

[0105] Alternatively, when the OAM server sends a second configuration message to the target relay node, the target relay node, in response to the second configuration message and provided that its power supply information meets the target conditions, adjusts itself to the target operating state and then sends the operating information to at least one of the following devices: the OAM server, the host node, the parent relay node, and the child relay node. For example, after receiving the operating information, the host node can promptly learn the target operating state of the target relay node, improving the efficiency of service management and resource allocation. Similarly, after receiving the operating information, the parent and child relay nodes can promptly learn the target operating state of the target relay node and adjust their time-frequency resource configurations based on this state to ensure service quality.

[0106] Optionally, after sending a first configuration message to the target relay node when the power supply information of the target relay node meets the target conditions, the host node or OAM server sends a fourth configuration message to the parent relay node and / or child relay node of the target relay node; wherein, the fourth configuration message is used to notify the parent relay node and / or child relay node about the target operating status of the target relay node.

[0107] Optionally, when the power supply information of the target relay node meets the target conditions, the host node or OAM server sends a first configuration message to the target relay node to notify it to adjust to the target operating state. Afterward, it may send a fourth configuration message to the parent relay node and / or child relay node of the target relay node. This fourth configuration message informs the parent relay node and / or child relay node about the target operating state of the target relay node. Upon receiving the fourth configuration message from the host node or OAM server, the parent relay node and / or child relay node adjust their operating parameters based on the fourth configuration message. It should be noted that the operating parameters indicated in the fourth configuration message correspond to the operating parameters of the target operating state. For example, during the inactive period of the target relay node, the parent relay node and / or child relay node also stop relaying with the target relay node to avoid invalid transmissions and ensure service quality.

[0108] Figure 7 This is a flowchart illustrating the power supply method provided in this application embodiment, which is applied to a host node or OAM server, such as... Figure 7 As shown, the method includes the following steps:

[0109] Step 701: If the power supply information of the target relay node meets the target conditions, send a first configuration message to the target relay node; wherein, the first configuration message is used to configure the target relay node to adjust to the target operating state; the target relay node is powered by renewable energy; the target operating state includes a power-saving state or a normal state; the power consumption of the target relay node in the power-saving state is less than the power consumption of the target relay node in the normal state;

[0110] Step 702: Send a fourth configuration message to the parent relay node and / or child relay node of the target relay node; wherein the fourth configuration message is used to notify the parent relay node and / or child relay node about the target operating status of the target relay node.

[0111] It should be noted that the explanation and interpretation of step 701 can refer to step 601 above, and the same technical effect can be achieved. To avoid repetition, it will not be repeated here.

[0112] Optionally, if the power supply information of the target relay node meets the target conditions, the host node or OAM server sends a first configuration message to the target relay node to notify it to adjust to the target operating state. Afterward, it may send a fourth configuration message to the parent relay node and / or child relay node of the target relay node. This fourth configuration message is used to notify the parent relay node and / or child relay node of the target operating state of the target relay node. Upon receiving the fourth configuration message from the host node or OAM server, the parent relay node and / or child relay node adjust their operating parameters based on the fourth configuration message.

[0113] The power supply method provided in this application embodiment involves the host node or OAM server sending a first configuration message to the target relay node, and then sending a fourth configuration message to the parent relay node and / or child relay node of the target relay node to configure the parent relay node and / or child relay node to adjust their operating parameters, thereby avoiding invalid transmission and ensuring service quality.

[0114] Figure 8 This is the seventh flowchart illustrating the power supply method provided in this application embodiment. The method is executed by the target relay node and the host node in cooperation, such as... Figure 8 As shown, the method includes the following steps:

[0115] Step 801: The target relay node sends a first report to the host node; wherein the first report is used to indicate that the target relay node is powered by renewable energy.

[0116] Step 802: After receiving the first report, the host node sends a third configuration message to the target relay node; wherein, the third configuration message is used to configure the target relay node to send a power supply status report; the power supply status report is used to report the power supply information of the target relay node.

[0117] Step 803: After receiving the third configuration message, the target relay node responds to the third configuration message by sending a power supply status report of the target relay node to the host node.

[0118] Step 804: After receiving the power supply status report sent by the target relay node, the host node sends a first configuration message to the target relay node if the power supply information of the target relay node meets the target conditions; wherein, the first configuration message is used to configure the target relay node to adjust to the target operating state; the target operating state includes a power saving state or a normal state; the power consumption of the target relay node in the power saving state is less than the power consumption of the target relay node in the normal state.

[0119] Step 805: After receiving the first configuration message, the target relay node responds to the first configuration message by adjusting the target relay node to the target running state.

[0120] The power supply method provided in this application embodiment sends a first configuration message to a target relay node through a host node to configure the target relay node to adjust to a target operating state. After receiving the first configuration message, the target relay node adjusts to the target operating state to change the power consumption of the target relay node, thereby improving the endurance of the target relay node powered by renewable energy and ensuring the ability of the target relay node to continuously provide relay transmission services when renewable energy power supply is limited.

[0121] Figure 9 This is the eighth flowchart illustrating the power supply method provided in this application embodiment. The method is executed collaboratively by the target relay node, the OAM server, and the host node. Figure 9 As shown, the method includes the following steps:

[0122] Step 901: The target relay node sends a first report to the OAM server; wherein the first report is used to indicate that the target relay node is powered by renewable energy.

[0124] Step 903: After receiving the second configuration message, the target relay node, in response to the second configuration message, adjusts the target relay node to the target operating state if the power supply information of the target relay node meets the target conditions.

[0125] Step 904: When the second configuration message is sent by the OAM server, the target relay node sends the running information to both the OAM server and the host node.

[0126] Optionally, when the second configuration message is sent by the OAM server, the target relay node may send operation information to at least one of the following devices: OAM server, host node, parent relay node, and child relay node.

[0127] Optionally, when the second configuration message is sent by the host node, the target relay node sends operation information to the host node, the operation information being used to indicate the target operation status of the target relay node; after receiving the operation information, the host node can promptly learn about the target operation status of the target relay node, thereby improving the efficiency of service management and resource allocation.

[0128] The power supply method provided in this application embodiment sends a second configuration message to the target relay node through an OAM server. When the target relay node receives the second configuration message and its power supply information meets the target conditions, it actively adjusts to the target operating state to change the power consumption of the target relay node, thereby improving the endurance of the target relay node powered by renewable energy and ensuring the ability of the target relay node to continuously provide relay transmission services when renewable energy power supply is limited.

[0129] It should be noted that the power supply method provided in this application embodiment can be executed by a power supply device, or by a control module within the power supply device for executing the power supply method.
