Description

[Technical Field]

[0001] TECHNICAL FIELD This application relates to the field of power technology, and more particularly to a network device and method for determining power supply relationships. [Background technology]

[0002] This application claims priority from the applicant of Chinese Patent Application No. 202110990376.1, entitled "NETWORK DEVICE AND METHOD FOR DETERMINING POWER SUPPLY RELATIONSHIP," filed on August 26, 2021, the contents of which are hereby incorporated by reference in their entirety.

[0003] Since a network device such as a base station covers more frequency bands, the base station has separate radio frequency units for each frequency band, which are powered by using different power supply units.

[0004] Since there are multiple radio frequency units and multiple power supply units, when the base station needs to perform an operation such as turning off or reducing the power supply to a specific radio frequency unit, the base station needs to first determine which power supply unit will supply power to the radio frequency unit, i.e., determine the power supply relationship.

[0005] In the prior art, the power supply relationship is determined manually. For example, determining the power supply unit that supplies power to the radio frequency unit is implemented by manually checking the line at the base station location. This method requires a lot of time and effort, and also imposes relatively high technical requirements on the operator, and manual checking is prone to errors. Summary of the Invention

[0006] The present application provides a network device and method for determining a power supply relationship between a power supply unit and a radio frequency unit, the power supply relationship being determined without manual intervention by controlling the load on the carrier of the radio frequency unit to change according to a rule.

[0007] According to a first aspect, the present application provides a network device. The network device includes a plurality of power supply units, a plurality of radio frequency units, and a control unit. Each of the plurality of radio frequency units is connected to at least one of the plurality of power supply units. The control unit is connected to both the plurality of power supply units and the plurality of radio frequency units.

[0008] The control unit is configured to control the load on the first carrier to change in a first manner, the first carrier being one of the carriers of the multiple radio frequency units, and when the load on the first carrier changes in the first manner, obtain power consumption of the multiple power supply units, and determine a first target power supply unit from the multiple power supply units that supplies power to the radio frequency unit corresponding to the first carrier based on the power consumption of the multiple power supply units, and the manner in which the power consumption of the first target power supply unit changes is consistent with the first manner.

[0009] In an embodiment of the present application, to obtain the power supply relationship between the power supply unit and the radio frequency unit, the control unit controls the load on the carrier of the radio frequency unit to change in a first manner. The change in the load on the carrier causes a change in the power consumption of the power supply unit that supplies power to the radio frequency unit. In this way, the control unit selects a power supply unit whose change in power consumption matches the first manner based on the change in the power consumption of each power supply unit, and determines the power supply relationship between the power supply unit and the radio frequency unit. This method does not require manual intervention, saves time and effort, and ensures the accuracy of the power supply relationship.

[0010] For example, a first mode includes the load on the first carrier periodically alternating between a first load and a second load, the first load being greater than the second load.

[0011] For example, in each cycle, the first load has a duration range of 2 to 5 seconds, and the second load has a duration range of 2 to 5 seconds.

[0012] Herein, the duration of the first load and the duration of the second load may be the same, thereby simplifying control, although, of course, alternatively, the duration of the first load and the duration of the second load may be different.

[0013] In an implementation of the present application, the control unit is configured to determine, based on the power consumption of the multiple power supply units, whether a time period during which a first power supply unit among the multiple power supply units is at a first power consumption corresponds to a time period during which a first carrier is under a first load, and whether a time period during which the first power supply unit is at a second power consumption corresponds to a time period during which the first carrier is under a second load, wherein the first power consumption is greater than the second power consumption and the first power supply unit is any of the multiple power supply units, and the control unit determines that the first power supply unit is a first target power supply unit if the time period during which a first power supply unit among the multiple power supply units is at the first power consumption corresponds to a time period during which the first carrier is under the first load and the time period during which the first power supply unit is at the second power consumption corresponds to a time period during which the first carrier is under the second load.

[0014] For example, the load on the first carrier changes periodically. In each period, the duration of the first load is 2 seconds, and the duration of the second load is 3 seconds. In this case, the load on the first carrier changes in the following manner: the first carrier alternately stays under the first load for 2 seconds and the second load for 3 seconds. When the load on the first carrier is controlled to change in the above manner, the power consumption of the first target power supply unit also shows the same change trend, i.e., the first target power supply unit alternately stays under the first power consumption for 2 seconds and the second power consumption for 3 seconds.

[0015] Therefore, the durations of the power supply units at the first power consumption and the second power consumption are determined, and when the durations correspond to the durations of the first load and the second load with respect to the carrier load, a power supply relationship between the power supply unit and the radio frequency unit can be determined.

[0016] To avoid the influence of determining the above-mentioned power supply relationship on normal service transmission, the control unit may choose to perform the above-mentioned operation when the amount of service is relatively low.

[0017] For example, the control unit is further configured to determine an amount of services transmitted on the first carrier before controlling the load on the first carrier to change in a first manner, and when the amount of services transmitted is less than a threshold, control the load on the first carrier to change in the first manner.

[0018] Even if the amount of the service transmitted on the first carrier is small, it may affect normal service transmission if transmitted in the manner described herein. Therefore, before controlling the load on the first carrier to change in the first manner, the control unit is further configured to migrate the service on the first carrier to a second carrier when the amount of the service transmitted is smaller than a threshold, the second carrier being any carrier of the plurality of radio frequency units other than the radio frequency unit corresponding to the first carrier.

[0019] For example, after determining the power supply relationship between the radio frequency units and the power supply units of the first carrier, the control unit is further configured to control the load on the third carrier to change in a second manner, the third carrier being any carrier of the multiple radio frequency units excluding the radio frequency unit corresponding to the first carrier, and when the load on the third carrier changes in the second manner, obtain the power consumption of the multiple power supply units, and determine a second target power supply unit from the multiple power supply units based on the power consumption of the multiple power supply units, and the manner in which the power consumption of the second target power supply unit changes is consistent with the second manner.

[0020] For example, the control unit is further configured to notify the control device of information regarding a first target power supply unit that supplies power to the radio frequency unit corresponding to the first carrier, thereby enabling the control device to generate a power supply topology of the radio frequency unit.

[0021] According to a second aspect, the present application provides a method for determining a power supply relationship, the method comprising: controlling a load on a first carrier to vary in a first manner, the first carrier being a carrier of any of a plurality of radio frequency units in a network device; obtaining power consumption of a plurality of power supply units in the network device when a load on a first carrier changes in a first manner; determining a first target power supply unit from the plurality of power supply units based on the power consumption of the plurality of power supply units to supply power to the radio frequency unit corresponding to the first carrier, wherein the manner in which the power consumption of the first target power supply unit changes is consistent with the first manner; Includes.

[0022] For example, a first mode includes the load on the first carrier periodically alternating between a first load and a second load, the first load being greater than the second load.

[Figure 4] FIG. 2 is a block diagram of a network device according to an embodiment of the present application. DETAILED DESCRIPTION OF THE INVENTION

[0043] To make the objectives, technical solutions and advantages of the present application clearer, the following describes the implementation of the present application in more detail with reference to the accompanying drawings.

[0044] 1 is a schematic structural diagram of a network device according to an embodiment of the present application. Referring to FIG. 1, the network device includes: a plurality of power supply units 10, a plurality of radio frequency units 20, and a control unit 30.

[0045] 1 , each of the multiple radio frequency units 20 is connected to one of the multiple power supply units 10, i.e., each radio frequency unit 20 needs to be powered by one power supply unit 10, and each power supply unit 10 may supply power to one or more radio frequency units 20. The control unit 30 is connected to both the multiple power supply units 10 and the multiple radio frequency units 20.

[0046] Of course, in this application, each radio frequency unit is not limited to being connected to only one power supply unit, in another implementation each radio frequency unit will be connected to, i.e., powered by, two or more power supply units.

[0047] For example, the network device is a base station. The base station covers multiple frequency bands, for example, 2G / 3G, 4G, and 5G. Multiple radio frequency units 20 are deployed in the base station to support the multiple frequency bands. The frequency bands supported by any two of the multiple radio frequency units 20 may be the same or different.

[0048] For example, the power supply unit 10 includes power management units (PMUs), the radio frequency unit 20 includes remote radio units (RRUs), and the control unit 30 includes baseband units (BBUs).

[0049] For example, one PMU includes one main power supply and one backup power supply.

[0050] For example, the control unit 30 includes multiple BBUs, and each BBU is connected to several PMUs and RRUs.

[0051] In the implementation of this embodiment of the present application, the control unit 30 is configured to control the load on a first carrier to change in a first manner, the first carrier being any carrier of the multiple radio frequency units, and when the load on the first carrier changes in the first manner, obtain the power consumption of the multiple power supply units, and determine a first target power supply unit from the multiple power supply units that supplies power to the radio frequency unit corresponding to the first carrier based on the power consumption of the multiple power supply units, and the manner in which the power consumption of the first target power supply unit changes is consistent with the first manner.

[0052] The power consumption of the power supply unit includes a plurality of sampled values ​​of the power consumption of the power supply unit during a time period in which the load on the first carrier changes in a first manner, each sampled value representing the power consumption of the power supply unit in a unit time.

[0053] In an embodiment of the present application, to obtain the power supply relationship between the power supply unit and the radio frequency unit, the control unit controls the load on the carrier of the radio frequency unit to change in a first manner. The change in the load on the carrier causes a change in the power consumption of the power supply unit that supplies power to the radio frequency unit. In this way, the control unit selects a power supply unit whose change in power consumption matches the first manner based on the change in the power consumption of each power supply unit, and determines the power supply relationship between the power supply unit and the radio frequency unit. This method does not require manual intervention, saves time and effort, and ensures the accuracy of the power supply relationship.

[0054] In a possible implementation, the first manner includes periodically alternating the load on the first carrier between a first load and a second load, where the first load is greater than the second load. Correspondingly, the power consumption of the first target power supply unit also periodically alternating. When the power supply unit is under the first load, the power consumption of the power supply unit is high, and when the power supply unit is under the second load, the power consumption of the power supply unit is low. Therefore, the first target power supply unit can be accurately determined based on the power consumption of each power supply unit.

[0055] For example, in each cycle, the duration range of the first load is 2 seconds to 5 seconds, and the duration range of the second load is 2 seconds to 5 seconds. If the duration range is too short, it may be difficult to accurately identify the power supply relationship. If the duration range is too long, it may be slow to determine the power supply relationship.

[0056] Herein, the duration of the first load and the duration of the second load may be the same, thereby simplifying control, although, of course, alternatively, the duration of the first load and the duration of the second load may be different.

[0057] In another possible implementation, the first regime may not be periodic, for example, the first regime may include alternating loads on the first carrier between a first load and a second load, but with a different duration for the first load each time, or a different duration for the second load each time.

[0058] For example, the first load is full load, ie transmission occurs at the maximum transmission rate per unit time on the carrier, and the second load is no load, ie no transmission occurs per unit time.

[0059] In an embodiment of the present application, when determining the power supply relationship, the control unit may control the amount of data provided to the radio frequency unit in each time period, for example, in a first time period, the radio frequency unit is provided with the maximum transmission amount of data that can be transmitted by the radio frequency unit, so that the radio frequency unit is fully loaded to transmit data in the first time period, and in a second time period, no data is provided to the radio frequency unit, so that the radio frequency unit has no data to transmit in the second time period, which corresponds to the no-load state mentioned above.

[0060] In other implementations, at least one of the first load and the second load may be between a full load and no load.

[0061] As described above, the power supply unit 10 includes a PMU. The PMU has a sensor component for detecting power consumption. The control unit can obtain the power consumption of the power supply unit by collecting the detection results from the sensor component.

[0062] In an embodiment of the present application, the control unit 30 may determine the power supply relationship in the following manner. Determine, based on the power consumptions of the plurality of power supply units, whether a time period during which a first power supply unit of the plurality of power supply units is at a first power consumption corresponds to a time period during which the first carrier is under a first load, and whether a time period during which the first power supply unit is at a second power consumption corresponds to a time period during which the first carrier is under a second load, wherein the first power consumption is greater than the second power consumption, and the first power supply unit is any of the plurality of power supply units; If a time period during which a first power supply unit of the plurality of power supply units is at a first power consumption corresponds to a time period during which a first carrier is under a first load, and a time period during which the first power supply unit is at a second power consumption corresponds to a time period during which the first carrier is under a second load, the first power supply unit is determined to be a first target power supply unit.

[0063] For example, the load on the first carrier changes periodically. In each cycle, the duration of the first load is 2 seconds, and the duration of the second load is 3 seconds. In this case, the load on the first carrier changes in the following manner: the first carrier alternately stays under the first load for 2 seconds and the second load for 3 seconds. When the load on the first carrier is controlled to change in the above manner, the power consumption of the first target power supply unit also shows the same change trend, i.e., the first target power supply unit alternately stays under the first power consumption for 2 seconds and the second power consumption for 3 seconds.

[0064] Therefore, the durations of the power supply units at the first power consumption and the second power consumption are determined, and when the durations correspond to the durations of the first load and the second load with respect to the carrier load, a power supply relationship between the power supply unit and the radio frequency unit can be determined.

[0065] For example, the following scheme may be used to determine whether a time period during which a first power supply unit of a plurality of power supply units is at a first power consumption corresponds to a time period during which a first carrier is under a first load, and whether a time period during which the first power supply unit is at a second power consumption corresponds to a time period during which the first carrier is under a second load.

[0066] For example, the values ​​of power consumption and load are converted into 0 and 1 and expressed. For example, a first power consumption and a first load are expressed as 1, and a second power consumption and a second load are expressed as 0. If the bit representing the power consumption and the bit representing the load are the same at each time point, it is determined that a time period during which a first power supply unit among the multiple power supply units is at a first power consumption corresponds to a time period during which a first carrier is under the first load, and a time period during which a first power supply unit is at a second power consumption corresponds to a time period during which a first carrier is under the second load. If the bit representing the load and the bit representing the power consumption are different at each time point, the above-mentioned time periods do not correspond.

[0067] In another example, the changes in power consumption and load are converted into a waveform diagram. For example, a first power consumption and a first load correspond to the same upper bit in the waveform, and a second power consumption and a second load correspond to the same lower bit in the waveform. If the waveform indicating the changes in power consumption and the waveform indicating the changes in load match, it is determined that the time period during which a first power supply unit among the multiple power supply units is at a first power consumption corresponds to the time period during which a first carrier is under the first load, and the time period during which a first power supply unit is at a second power consumption corresponds to the time period during which a first carrier is under the second load. If the bits representing the load and the bits representing the power consumption at each time point are different, the above-mentioned time periods do not correspond.

[0068] To avoid the influence of determining the above-mentioned power supply relationship on normal service transmission, the control unit may choose to perform the above-mentioned operation when the amount of service is relatively low.

[0069] For example, the control unit 30 is further configured to determine an amount of services transmitted on the first carrier before controlling the load on the first carrier to change in a first manner, and when the amount of services transmitted is less than a threshold, control the load on the first carrier to change in the first manner.

[0070] The threshold may be set based on the daily service transmission volume of the network device, ensuring that the amount of service transmitted by the network device is at a relatively low level when the method is performed.

[0071] Even if the amount of a service transmitted on the first carrier is small, it may affect normal service transmission if transmitted in the manner described herein. Therefore, before controlling the load on the first carrier to change in the first manner, the control unit 30 is further configured to migrate the service on the first carrier to a second carrier when the amount of the service transmitted is smaller than a threshold, the second carrier being any carrier of the multiple radio frequency units other than the radio frequency unit corresponding to the first carrier. The service on the first carrier is transferred to ensure normal service transmission.

[0072] For example, the control unit 30 may restrict the service from accessing the first carrier and cause the service to be migrated to the second carrier. Alternatively, the control unit 30 may actively hand over the service to the second carrier.

[0073] Optionally, the control unit 30 is further configured to transition the service on the second carrier back to the first carrier after determining the power supply unit that supplies power to the radio frequency unit of the first carrier.

[0074] In an embodiment of the present application, the control unit 30 may traverse each radio frequency unit in the network device in the manner of determining the power supply relationship between the radio frequency unit of the first carrier and the power supply unit, determine the power supply relationship between each radio frequency unit and the power supply unit, and obtain a power supply topology, which includes the connection relationship between each radio frequency unit and the power supply unit.

[0075] For example, after determining the power supply relationship between the radio frequency units and the power supply units of the first carrier, the control unit is further configured to control the load on the third carrier to change in a second manner, the third carrier being any carrier of the multiple radio frequency units excluding the radio frequency unit corresponding to the first carrier, and when the load on the third carrier changes in the second manner, obtain the power consumption of the multiple power supply units, and determine a second target power supply unit from the multiple power supply units based on the power consumption of the multiple power supply units, and the manner in which the power consumption of the second target power supply unit changes is consistent with the second manner.

[0076] For example, the third carrier and the second carrier mentioned above may be the same carrier or different carriers.

[0077] For example, the second manner and the first manner described above are the same rule, which makes it easier for the control unit to perform control. In another implementation, the second manner and the first manner described above are different rules.

[0078] For example, in the present application, the carriers may be numbered, for example, C0, C1, ..., Cn, and the power supply units that supply power to the radio frequency units corresponding to the carriers are determined sequentially.

[0079] For example, the control unit 30 first migrates services on a carrier Cx to another carrier, then determines a power supply unit that supplies power to the radio frequency units corresponding to the carrier Cx, and after the power supply unit that supplies power to the radio frequency units corresponding to the carrier Cx has been determined, migrates the services migrated to the other carrier back to the carrier Cx. In the same manner, the control unit 30 processes a carrier Cx+1 and determines a power supply unit that supplies power to the radio frequency units corresponding to the carrier Cx+1. Finally, a power supply unit corresponding to each radio frequency unit is determined. x is an integer ranging from 0 to n, where n is a positive integer.

[0080] As described above, in the present application, the control unit may include multiple BBUs, each connected to several RRUs. In this case, each BBU may determine the power supply relationship of the connected RRUs. The power supply relationship of the RRUs determined by the BBU is summarized and reported to one of the RRUs or an upper-layer network management system, and the one of the RRUs or the upper-layer network management system generates a power supply topology.

[0081] For example, the control unit 30 is further configured to inform the control device of information regarding a first target power supply unit that supplies power to the radio frequency unit corresponding to the first carrier, thereby enabling the control device to generate a power supply topology of the radio frequency unit.

[0082] The control device herein may be the above-mentioned upper layer network management system.

[0083] In the embodiment of the present application, the power supply topology refers to the connection relationship between each radio frequency unit and the corresponding power supply unit.

[0084] Table 1 below provides an example of a power supply topology. The carriers that can be provided by the radio frequency unit correspond to several frequency bands: G, U, L, and NR. G corresponds to 2G, U corresponds to 3G, L corresponds to 4G, and NR corresponds to 5G.

[0085] [Table 1]

[0086] Referring to Table 1, each power supply unit corresponds to one or more radio frequency units. For example, PMU0# corresponds to RRU0# and RRU2#, PMU1# corresponds to RRU1#, RRU4#, and RRU5#, and PMUn# corresponds to RRU3#. In addition, the power supply topology table further indicates the carrier corresponding to each radio frequency unit. For example, RRU0# corresponds to carrier C0, and RRU1# corresponds to carrier C1. It should be noted that the correspondence between RRUs and carriers already exists in the BBU.

[0087] In an embodiment of the present application, after obtaining the power supply topology, the control unit 30 may perform power supply management based on the power supply topology. For example, turning off the power supply of a designated radio frequency unit specifically includes first determining a power supply unit corresponding to the radio frequency unit based on the power supply topology, and then controlling the power supply unit to power off the radio frequency unit. In another example, reducing the power of a designated carrier specifically includes first determining a power supply unit corresponding to the carrier's radio frequency unit based on the power supply topology, and then controlling the power supply unit to reduce the power. The control unit 30 may control the power supply unit by sending an instruction to the power supply unit.

[0088] According to the above solution, the power supply relationship between each radio frequency unit and the power supply unit in the network device can be obtained, and therefore operations such as precise power preparation and accurate power consumption mode switching of the network device can be implemented based on the power supply relationship.

[0089] 2 is a flowchart of a method for determining a power supply relationship according to an embodiment of the present application. The method is performed by the control unit of FIG. 1. Referring to FIG. 2, the method includes the following steps:

[0090] 201: Control a load on a first carrier to vary in a first manner, the first carrier being any carrier of a plurality of radio frequency units in a network device.

[0091] 202: Obtain power consumption of a plurality of power supply units in a network device when a load on a first carrier changes in a first manner.

[0092] 203. Determine a first target power supply unit from the plurality of power supply units based on the power consumption of the plurality of power supply units, which supplies power to the radio frequency unit corresponding to the first carrier, and the manner in which the power consumption of the first target power supply unit changes is consistent with the first manner.

[0093] In an embodiment of the present application, to obtain the power supply relationship between the power supply unit and the radio frequency unit, the control unit controls the load on the carrier of the radio frequency unit to change in a first manner. The change in the load on the carrier causes a change in the power consumption of the power supply unit that supplies power to the radio frequency unit. In this way, the control unit selects a power supply unit whose change in power consumption matches the first manner based on the change in the power consumption of each power supply unit, and determines the power supply relationship between the power supply unit and the radio frequency unit. This method does not require manual intervention, saves time and effort, and ensures the accuracy of the power supply relationship.

[0094] In a possible implementation, the first manner includes periodically alternating the load on the first carrier between a first load and a second load, where the first load is greater than the second load. Correspondingly, the power consumption of the first target power supply unit also periodically alternating. When the power supply unit is under the first load, the power consumption of the power supply unit is high, and when the power supply unit is under the second load, the power consumption of the power supply unit is low. Therefore, the first target power supply unit can be accurately determined based on the power consumption of each power supply unit.

[0095] For example, in each cycle, the first load has a duration range of 2 to 5 seconds, and the second load has a duration range of 2 to 5 seconds.

[0096] Herein, the duration of the first load and the duration of the second load may be the same, thereby simplifying control, although, of course, alternatively, the duration of the first load and the duration of the second load may be different.

[0097] In another possible implementation, the first regime may not be periodic, for example, the first regime may include alternating loads on the first carrier between a first load and a second load, but with a different duration for the first load each time, or a different duration for the second load each time.

[0098] For example, the first load is full load, ie transmission occurs at the maximum transmission rate per unit time on the carrier, and the second load is no load, ie no transmission occurs per unit time.

[0099] In other implementations, at least one of the first load and the second load may be between a full load and no load.

[0100] In this embodiment of the present application, step 203 includes: determining, based on power consumptions of the plurality of power supply units, whether a time period during which a first power supply unit of the plurality of power supply units is at a first power consumption corresponds to a time period during which a first carrier is under a first load, and whether a time period during which the first power supply unit is at a second power consumption corresponds to a time period during which the first carrier is under a second load, where the first power consumption is greater than the second power consumption and the first power supply unit is any of the plurality of power supply units; determining that a first power supply unit of the plurality of power supply units is a first target power supply unit if a time period during which the first power supply unit is at a first power consumption corresponds to a time period during which the first carrier is under a first load and a time period during which the first power supply unit is at a second power consumption corresponds to a time period during which the first carrier is under a second load; may include:

[0101] For example, the load on the first carrier changes periodically. In each period, the duration of the first load is 2 seconds, and the duration of the second load is 3 seconds. In this case, the load on the first carrier changes in the following manner: the first carrier alternately stays under the first load for 2 seconds and the second load for 3 seconds. When the load on the first carrier is controlled to change in the above manner, the power consumption of the first target power supply unit also shows the same change trend, i.e., the first target power supply unit alternately stays under the first power consumption for 2 seconds and the second power consumption for 3 seconds.

[0102] Therefore, the durations of the power supply units at the first power consumption and the second power consumption are determined, and when the durations correspond to the durations of the first load and the second load with respect to the carrier load, a power supply relationship between the power supply unit and the radio frequency unit can be determined.

[0103] For example, the following scheme may be used to determine whether a time period during which a first power supply unit of a plurality of power supply units is at a first power consumption corresponds to a time period during which a first carrier is under a first load, and whether a time period during which the first power supply unit is at a second power consumption corresponds to a time period during which the first carrier is under a second load.

[0104] For example, the values ​​of power consumption and load are converted into 0 and 1 and expressed. For example, a first power consumption and a first load are expressed as 1, and a second power consumption and a second load are expressed as 0. If the bit representing the power consumption and the bit representing the load are the same at each time point, it is determined that a time period during which a first power supply unit among the multiple power supply units is at a first power consumption corresponds to a time period during which a first carrier is under the first load, and a time period during which a first power supply unit is at a second power consumption corresponds to a time period during which a first carrier is under the second load. If the bit representing the load and the bit representing the power consumption are different at each time point, the above-mentioned time periods do not correspond.

[0105] In another example, the changes in power consumption and load are converted into a waveform diagram. For example, a first power consumption and a first load correspond to the same upper bit in the waveform, and a second power consumption and a second load correspond to the same lower bit in the waveform. If the waveform indicating the changes in power consumption and the waveform indicating the changes in load match, it is determined that the time period during which a first power supply unit among the multiple power supply units is at a first power consumption corresponds to the time period during which a first carrier is under the first load, and the time period during which a first power supply unit is at a second power consumption corresponds to the time period during which a first carrier is under the second load. If the bits representing the load and the bits representing the power consumption at each time point are different, the above-mentioned time periods do not correspond.

[0106] To avoid the influence of determining the above-mentioned power supply relationship on normal service transmission, the control unit may choose to perform the above-mentioned operation when the amount of service is relatively low.

[0107] Optionally, before controlling the load on the first carrier to vary in a first manner, the method further comprises: determining an amount of service to be transmitted on a first carrier; controlling the load on the first carrier to vary in a first manner when the amount of the service being transmitted is less than a threshold; Further includes:

[0108] Even if the volume of the service transmitted on the first carrier is small, if the service is transmitted in the manner described in this application, it may affect normal service transmission. Therefore, before controlling the load on the first carrier to change in a first manner, the method includes: The method further includes the step of transferring the service on the first carrier to a second carrier when the amount of the service being transmitted is less than a threshold, the second carrier being any carrier of the plurality of radio frequency units other than the radio frequency unit corresponding to the first carrier, and the service on the first carrier is transferred to ensure normal service transmission.

[0109] In an embodiment of the present application, the control unit 30 may traverse each radio frequency unit in the network device in the manner of determining the power supply relationship between the radio frequency unit of the first carrier and the power supply unit, determine the power supply relationship between each radio frequency unit and the power supply unit, and obtain a power supply topology, which includes the connection relationship between each radio frequency unit and the power supply unit.

[0110] For example, after determining the power supply relationship between the radio frequency unit and the power supply unit of the first carrier, the method includes: controlling a load on a third carrier to vary in a second manner, the third carrier being any carrier of the plurality of radio frequency units other than the radio frequency unit corresponding to the first carrier; obtaining power consumption of the plurality of power supply units when the load on the third carrier varies in a second manner; determining a second target power supply unit from the plurality of power supply units based on the power consumption of the plurality of power supply units, wherein the manner in which the power consumption of the second target power supply unit changes is consistent with the second manner; Further includes:

[0111] For example, the third carrier and the second carrier mentioned above may be the same carrier or different carriers.

[0112] For example, the second manner and the first manner described above are the same rule, which makes it easier for the control unit to perform control. In another implementation, the second manner and the first manner described above are different rules.

[0113] For example, in the present application, the carriers may be numbered, for example, C0, C1, ..., Cn, and the power supply units that supply power to the radio frequency units corresponding to the carriers are determined sequentially.

[0114] 3 is a flowchart of a method for determining a power supply relationship according to an embodiment of the present application. The method is performed by the control unit of FIG. 1. Referring to FIG. 3, the method includes the following steps:

[0115] 211: Transfer service on carrier Cx to another carrier.

[0116] x is an integer ranging from 0 to n, where n is a positive integer.

[0117] 212: Determine a power supply unit that supplies power to a radio frequency unit corresponding to the carrier Cx.

[0118] 213: After the power supply unit that supplies power to the radio frequency unit corresponding to the carrier Cx is determined, the service that has been migrated to another carrier is migrated back to the carrier Cx.

[0119] Then, carrier Cx+1 is processed in the same manner, ie, the following steps are included:

[0120] 214: Transfer service on carrier Cx+1 to another carrier

[0121] 215: Determine the power supply unit that supplies power to the radio frequency unit corresponding to the carrier Cx+1.

[0122] 216: After the power supply unit that supplies power to the radio frequency unit corresponding to the carrier Cx+1 is determined, the service that has been migrated to another carrier is migrated back to the carrier Cx+1.

[0123] The above steps S211 to S216 are cyclically performed, and finally, a power supply unit corresponding to each radio frequency unit is obtained.

[0124] In this application, the control unit may include multiple BBUs, each connected to several RRUs. In this case, each BBU may determine the power supply relationship of the connected RRUs. The power supply relationship of the RRUs determined by the BBU is summarized and reported to one of the RRUs or an upper-layer network management system, and the one of the RRUs or the upper-layer network management system generates a power supply topology.

[0125] For example, this method The method further includes notifying the control device of information regarding a first target power supply unit that supplies power to the radio frequency unit corresponding to the first carrier, thereby enabling the control device to generate a power supply topology of the radio frequency unit.

[0126] The control device herein may be the above-mentioned upper layer network management system.
