Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a base station control method, device, base station and storage medium. Background Art

[0002] With the rapid development of the wireless communication market, especially the development of 5G (fifth generation cellular technology) networks in recent years, operators have deployed a large number of wireless networks of various standards through base stations. In this case, the total power consumption of the network is increasing, resulting in higher and higher operation and maintenance costs.

[0003] In the prior art, in order to reduce operation and maintenance costs and reduce network power consumption, the radio frequency unit is often turned off to reduce power consumption. Carrier shutdown energy saving is an energy-saving method that turns off the radio frequency PA (Power Amplifier). However, traditional carrier shutdown energy saving only turns off the radio frequency PA, and only when the loads of all carriers on the AAU (Active Antenna Unit) meet the energy-saving conditions can the radio frequency PA be turned off to achieve the final energy-saving effect. However, due to the uneven load of each carrier in the actual network, only some low-load carriers can meet the carrier shutdown conditions, and the radio frequency PA cannot be turned off when some carriers are turned off. In this scenario, no energy-saving benefits can be generated, resulting in high energy consumption of the base station.

[0004] It can be seen that how to reduce the energy consumption of base stations is a technical issue worthy of attention. Summary of the invention

[0086] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

To facilitate the understanding of the embodiments of the present application, the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0088] In order to solve the technical problem of high energy consumption of base stations in the prior art, the present application provides a base station control method, which can reduce the energy consumption of the base station.

[0089] Figure 1 A flow chart of a base station control method provided for an embodiment of the present application. This method can be applied to one or more electronic devices such as a base station, a control unit of a base station, a server, etc. In addition, the execution subject of this method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the above-mentioned execution subject is software, this method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0090] In this embodiment, the base station includes a radio frequency unit, a device group, and a carrier, a single radio frequency unit corresponds to at least one device group, and a single device group corresponds to at least one carrier.

[0091] Here, each base station may include multiple RF units, and each RF unit may include a RF PA (Power Amplifier). RF PA is an important device in the RF front end. Its performance directly determines important factors such as signal strength, stability, power consumption, and user experience. Its core parameters include gain, bandwidth, efficiency, linearity, maximum output power, etc.

[0092] The device group may include one or more devices. For example, the device group may include but is not limited to MCS (Multichip Synchronization) chip devices.

[0093] Carrier refers to the carrier frequency bandwidth of the air interface working frequency band of the base station equipment, that is, the base station can intelligently turn on or off the transmission of signals within a certain bandwidth, and the output power of the bandwidth where the closed carrier is located should be zero.

[0094] like Figure 1 As shown, the method specifically includes:

[0095] Step 101: Acquire carrier configuration data of the radio frequency unit.

[0096] In this embodiment, the carrier configuration data may include the correspondence between the radio frequency unit, the device group and the carrier. According to the carrier configuration data, the correspondence between the carrier and the device group can be obtained. One device group corresponds to several carriers, and one carrier is distributed on those device groups. When the carrier configuration is changed, the correspondence between the carrier and the device group can be correctly maintained by updating the carrier configuration data.

[0097] Step 102: Determine the carrier corresponding to the radio frequency unit based on the carrier configuration data.

[0098] In this embodiment, since the carrier configuration data includes the correspondence between the radio frequency unit, the device group and the carrier, the carrier corresponding to the radio frequency unit can be determined based on the carrier configuration data.

[0099] Step 103 : When the carrier meets the preset shutdown condition, based on the carrier configuration data, control the device group corresponding to the carrier meeting the preset shutdown condition to be shut down.

[0100] In this embodiment, the preset shutdown condition can be used to determine whether to control the device group corresponding to the carrier to be shut down.

[0101] As an example, the carrier shutoff condition may include: the carrier load of each carrier corresponding to the device group is less than or equal to a preset threshold. Alternatively, the carrier shutoff condition may also include: each carrier corresponding to the first device group is migrated to the second device group, wherein the first device group may be any device group corresponding to the radio frequency unit. The second device group may be any one or more device groups corresponding to the radio frequency unit that are different from the first device group.

[0102] In some optional implementations of this embodiment, when each of the device groups corresponding to the radio frequency unit is turned off, the radio frequency unit is controlled to be turned off.

[0103] It can be understood that, when all the device groups corresponding to a single radio frequency unit are turned off, the radio frequency unit can be turned off to further reduce the energy consumption of the base station.

[0104] In the base station control method provided in the embodiment of the present application, the base station includes a radio frequency unit, a device group and a carrier, a single radio frequency unit corresponds to at least one device group, and a single device group corresponds to at least one carrier. The method obtains the carrier configuration data of the radio frequency unit, and then, based on the carrier configuration data, determines the carrier corresponding to the radio frequency unit, and then, when the carrier meets the preset shutdown condition, controls the device group corresponding to the carrier that meets the preset shutdown condition to be turned off based on the carrier configuration data. Thus, by controlling the device group corresponding to the carrier that meets the preset shutdown condition to be turned off, the energy consumption of the base station can be reduced when the carrier meets the preset shutdown condition.

[0105] Figure 2A A flow chart of another base station control method provided in an embodiment of the present application. The base station in this embodiment includes a radio frequency unit, a device group and a carrier, a single radio frequency unit corresponds to at least one device group, and a single device group corresponds to at least one carrier.

[0106] like Figure 2A As shown, the method specifically includes:

[0107] Step 201: Acquire carrier configuration data of the radio frequency unit.

[0108] In this embodiment, step 201 and Figure 1 Step 101 in the corresponding embodiment is basically the same and will not be described again here.

[0109] Step 202: Determine the carrier corresponding to the radio frequency unit based on the carrier configuration data.

[0110] In this embodiment, step 202 and Figure 1 Step 102 in the corresponding embodiment is basically the same and will not be described again here.

[0111] Step 203: When the carrier meets the preset shutdown condition, determine the device group corresponding to the carrier and the radio frequency unit based on the carrier configuration data.

[0112] In this embodiment, since the carrier configuration data includes the correspondence between the radio frequency unit, the device group and the carrier, the device group corresponding to the carrier and the radio frequency unit may be determined based on the carrier configuration data.

[0113] Step 204: Acquire the carrier load corresponding to the device group, and determine the device group to be shut down according to the carrier load.

[0114] In this embodiment, the carrier load corresponding to the device group may be the sum of the carrier loads of each carrier corresponding to the device group.

[0115] As an example, a device group whose carrier load is less than or equal to a preset threshold may be determined as a device group to be shut down.

[0116] As another example, the device group with the smallest carrier wave may be determined as the device group to be shut down.

[0117] Step 205: Control the device group to be shut down to shut down.

[0118] In this embodiment, after the device group to be turned off is determined, the device group can be turned off.

[0119] As an example of this embodiment, when an AAU has M carriers, the load conditions of the M carriers (i.e., the above-mentioned carrier loads) can be obtained periodically or in real time. When the carrier loads of carrier 1 and carrier 2 are lower than the set threshold, carrier 1 and carrier 2 are directly turned off, and device group 1 is also turned off to achieve the energy saving benefits brought by turning off device group 1. When the loads of carrier 3 and carrier 4 are lower than the set threshold, carrier 3 and carrier 4, as well as the corresponding device group 2, are directly turned off to achieve the energy saving benefits brought by turning off device group 2.

[0120] In some optional implementations of this embodiment, after determining the carrier corresponding to the radio frequency unit based on the carrier configuration data, the following steps may also be performed:

[0121] First, in the case that the carrier does not meet the preset shutdown condition, the carrier that does not meet the preset shutdown condition is controlled to be turned on.

[0122] Afterwards, based on the carrier configuration data, the device group corresponding to the turned-on carrier is controlled to be turned on.

[0123] As an example of the above optional implementation, if carrier 1 or carrier 2 does not meet the carrier shutdown condition due to factors such as increased load on the basic coverage layer, carrier 1 or carrier 2 is turned on, and the associated device group 1 needs to be turned on to meet the normal needs of the service. If carrier 3 and carrier 4 do not meet the carrier shutdown condition, carrier 3 or carrier 4 needs to be turned on, and the associated device group 2 also needs to be turned on.

[0124] It can be understood that in the above application scenario, when the carrier does not meet the preset shutdown condition, the carrier and the device group that do not meet the preset shutdown condition can be turned on to ensure the stable operation of the base station.

[0125] It should be noted that, in addition to the above contents, this embodiment may also include Figure 1 The corresponding technical features described in the corresponding embodiments are realized Figure 1 For details, please refer to the technical effect of the base station control method shown in Figure 1 For the sake of brevity, the relevant description is not repeated here.

[0126] The base station control method provided in the embodiment of the present application determines the device group to be shut down by the carrier load of the carrier corresponding to the device group. In this way, it can be determined whether the device group needs to be shut down to reduce the energy consumption of the base station based on the size of the carrier load.

[0127] Figure 2B A flow chart of another base station control method provided for an embodiment of the present application. The base station in this embodiment includes a radio frequency unit, a device group and a carrier, a single radio frequency unit corresponds to at least one device group, and a single device group corresponds to at least one carrier. A single radio frequency unit corresponds to a first device group and a second device group. That is, the radio frequency unit corresponds to at least two device groups. The at least two device groups include a first device group and a second device group. Here, the first device group may be one or more device groups from which a carrier is migrated out of the device group corresponding to the radio frequency unit. The second device group may be one or more device groups from which a carrier is migrated in the device group corresponding to the radio frequency unit.

[0128] like Figure 2B As shown, the method specifically includes:

[0129] Step 301: Acquire carrier configuration data of the radio frequency unit.

[0130] In this embodiment, step 301 and Figure 1 Step 101 in the corresponding embodiment is basically the same and will not be described again here.

[0131] Step 302: Determine the carrier corresponding to the radio frequency unit based on the carrier configuration data.

[0132] In this embodiment, step 302 and Figure 1 Step 102 in the corresponding embodiment is basically the same and will not be described again here.

[0133] Step 303: When the carrier meets the preset shutdown condition, determine the first device group corresponding to each carrier before migration based on the carrier configuration data.

[0134] In this embodiment, the preset shutdown condition includes that each of the carriers corresponding to the first device group is migrated to the second device group.

[0135] Since the carrier configuration data includes the correspondence between the radio frequency unit, the device group and the carrier, the first device group corresponding to each of the carriers before migration can be determined based on the carrier configuration data.

[0136] Step 304: Control each of the first device groups corresponding to the carrier waves to be turned off before migration.

[0137] In this embodiment, after determining the first device groups corresponding to each carrier before migration, the first device groups corresponding to each carrier before migration may be controlled to be turned off.

[0138] In some optional implementations of this embodiment, the first device group is determined in the following manner:

[0139] First, for each device group in at least one of the device groups, a device load of the device group is determined based on carrier loads of each of the carriers corresponding to the device group.

[0140] Here, the device load of the device group may be the sum of the carrier loads of the respective carriers corresponding to the device group.

[0141] Afterwards, the device group corresponding to the device load having the smallest determined value is determined as the first device group.

[0142] It can be understood that in the above optional implementation, the device group with the smallest device load can be used as the first device group, so that each carrier corresponding to the first device group can be migrated to the second device group, thereby reducing the device load of the device group to which the carrier is migrated to a certain extent.

[0143] In some optional implementations of this embodiment, the second device group is determined in the following manner:

[0144] For each carrier corresponding to the first device group, a device group whose difference between the limit device load and the current device load is greater than the carrier load of the carrier is determined from the device groups corresponding to the radio frequency units to obtain a second device group.

[0145] The limit device load may be a preset maximum load that the device can accommodate.

[0146] The current device load may be the sum of the carrier loads of each carrier currently actually accommodated by the device.

[0147] It can be understood that in the above optional implementation, it can be ensured that after each carrier corresponding to the first device group is migrated to the second device group, the device load of the second device group is less than or equal to its limit device load, thereby, the carrier migration can be performed within the device group's compliance capacity.

[0148] In some optional implementations of this embodiment, each of the carriers corresponding to the first device group may be migrated to the second device group in the following manner:

[0149] First, for each carrier corresponding to the first device group, a device group used to migrate the carrier is determined to obtain a second device group associated with the carrier.

[0150] Afterwards, each of the carriers corresponding to the first device group is migrated to the associated second device group.

[0151] As an example, when an AAU has N device groups, and each device group has M carriers, the load conditions of the M device groups and carriers are obtained periodically or in real time. When the loads of the M carriers do not meet the shutdown conditions, the device group with the lowest load (that is, the first device group mentioned above) can be analyzed. For example, if the load threshold cannot be higher than 20% (the percentage of the current load of the device group to the maximum load), when there is a difference between the load of other device groups and the load carrying capacity of the corresponding device group and is greater than the load of the device group with the lowest load, the carrier of the device group is migrated to other device groups, that is, the second device group mentioned above.

[0152] For example, if device group 1 is the lowest load device group, corresponding to carrier 1 and carrier 2, when the load carrying capacity of device group 2 and the load of device group 2 are greater than the load of carrier 1 and (the load carrying capacity of device group 3 - the load of device group 3) is greater than the load of carrier 2, carrier 1 of device group 1 is migrated to device group 2, carrier 2 of device group 1 is migrated to device group 3, and then device group 1 is shut down to achieve the energy saving benefits brought by shutting down device group 1. The carrier migration process is through the reconfiguration of the carrier and the switching of the associated device groups. The AAU migrates the configuration of carrier 1 from device group 1 to device group 2, so that no carrier is established on device group 1.

[0153] In addition, if the load of carrier 1, carrier 2, carrier 3, carrier 4, carrier 5, and carrier 6 increases, causing the corresponding device group 2 and device group 3 to accommodate a load higher than the migration threshold (for example, set to 60%), then device group 1 is opened and the configuration of carrier 1 and carrier 2 is restored to device group 1 to ensure service performance.

[0154] It can be understood that in the above optional implementation method, an associated second device group can be determined for each carrier corresponding to the first device group, so that each carrier in the first device group can be migrated to a different second device group respectively, thereby making the device load of other device groups except the first device group more balanced.

[0155] In some optional implementations of this embodiment, after controlling each of the first device groups corresponding to the carriers to be turned off before migration, the following steps may also be performed:

[0156] First, when the carrier does not meet the preset shutdown condition, the first device group is controlled to be turned on.

[0157] Afterwards, each of the migrated carriers is migrated back from the second device group to the first device group.

[0158] It can be understood that in the above optional implementation, when the carrier does not meet the preset shutdown condition, the first device group can be turned on and each carrier can be migrated back, so as to restore the corresponding relationship between each carrier and the first device group.

[0159] It should be noted that, in addition to the above contents, this embodiment may also include Figure 1 The corresponding technical features described in the corresponding embodiments are realized Figure 1 For details, please refer to the technical effect of the base station control method shown in Figure 1 For the sake of brevity, the relevant description is not repeated here.

[0160] The base station control method provided in the embodiment of the present application can reduce the energy consumption of the base station by shutting down the device group from which the carriers have been migrated after all carriers in the device group have been migrated to other device groups.

[0161] The following is an illustrative description of the embodiments of the present application, but it should be noted that the embodiments of the present application may have the features described below, but the following description does not constitute a limitation on the scope of protection of the embodiments of the present application.

[0162] With the rapid development of the wireless communication market, especially the development of 5G networks in recent years, operators have deployed a large number of wireless networks of various standards. In this case, the total power consumption of the network is getting higher and higher, resulting in higher and higher operation and maintenance costs for operators. In order to reduce the operation and maintenance costs of operators and reduce the power consumption of the network, the radio frequency unit is often turned off to reduce power consumption. Among them, carrier shutdown energy saving is a way to save energy by turning off the radio frequency PA (that is, the radio frequency unit mentioned above).

[0163] Traditional carrier shutdown energy saving only turns off the RF PA. Only when the load of all carriers on the AAU meets the energy saving conditions can the RF PA be turned off to achieve the ultimate energy saving effect. However, due to the uneven load of each carrier in the actual network, only some low-load carriers can meet the carrier shutdown conditions, and the RF PA cannot be turned off when some carriers are turned off. In this scenario, no energy saving benefits can be generated.

[0164] In the above scenario, by shutting down other devices of AAU (such as MCS chip, etc.), the energy saving benefits brought by shutting down the devices can be achieved to make up for the energy saving loss caused by shutting down the carrier but not the PA. At the same time, when all carriers meet the carrier shutdown conditions, other devices of AAU (such as MCS chip, etc.) can be shut down on the basis of shutting down the RF PA, and shutting down the devices and RF PA at the same time will bring higher energy saving benefits.

[0165] In this method, the structure of the base station can refer to Figure 3A As shown, Figure 3A A schematic diagram of the structure of a base station in a base station control method provided in an embodiment of the present application. The base station may include an AAU. The AAU may be configured with a carrier, a device group corresponding to the carrier, and finally a corresponding radio frequency channel PA. Figure 3B As shown, Figure 3B A schematic diagram of the correspondence between a radio frequency unit, a device group and a carrier in a base station control method provided in an embodiment of the present application.

[0166] This method mainly selects the device layer with low carrier load to shut down and save energy according to the device layer and its corresponding carrier load, so as to achieve energy saving effect. The device layer is a hardware layer between the carrier and the RF PA, supporting the establishment of the carrier and supporting dynamic shutdown and opening to achieve energy saving benefits. When all carriers meet the shutdown conditions, the carrier shutdown energy saving will enter the corresponding RF PA shutdown, and the device layer will be closed.

[0167] In this method, the underlying data maintenance may include:

[0168] 1. Maintain the device load carrying capacity.

[0169] Based on the device's own capabilities and product solution evaluation, evaluate which devices can be turned off to achieve energy saving, as well as the maximum load carrying capacity of these device groups, to form a collection of device groups (labeled as device group 1, device group 2, etc.).

[0170] 2. Identify the correspondence between carriers and device groups.

[0171] According to the carrier configuration of AAU (that is, the above-mentioned carrier configuration data), the correspondence between the carrier and the device group can be obtained. One device group corresponds to several carriers, and one carrier is distributed on those device groups. When the carrier configuration sends a change, the correspondence between the carrier and the device group can be correctly maintained.

[0172] 3. Load identification of carriers and device groups.

[0173] After the base station operates normally, the business load of the carrier is obtained (which can be obtained periodically or in real time), and a threshold is set according to the carrier load to determine whether it can be shut down for energy saving. At the same time, according to the relationship between the device groups corresponding to the carrier, the carrier load is converted to the load of the device group. The load of the device group is the sum of the loads of the associated carriers.

[0174] Specifically, the scheme for shutting down some carriers and device groups in this method is as follows:

[0175] 1. Flexible shutdown of some carriers and corresponding device groups.

[0176] When the carrier meets the shutdown condition, the corresponding device group (that is, the device group corresponding to the carrier that meets the preset shutdown condition) is turned off to obtain energy saving benefits of the device group. When all carriers meet the shutdown condition, all device groups and RF PA are turned off to obtain greater energy saving benefits.

[0177] 2. Some carriers and corresponding device groups are intelligently shut down.

[0178] When the carrier does not meet the carrier shutdown conditions and the device group cannot be shut down, the carrier is migrated to another device group through carrier configuration migration or service migration. When the device group is changed to a low-load device group, energy saving benefits are obtained by shutting down the device group.

[0179] Specifically, the following method can be used to control the closing of carriers and corresponding device groups: when an AAU has M carriers, the load conditions of the M carriers are obtained periodically or in real time. When the load of carrier 1 and carrier 2 is lower than the set threshold, carrier 1 and carrier 2 are directly closed, and device group 1 is also closed to achieve the energy saving benefits brought by closing device group 1; when the load of carrier 3 and carrier 4 is lower than the set threshold, carrier 3 and carrier 4 and the corresponding device group 2 are directly closed to achieve the energy saving benefits brought by closing device group 2, and so on. As shown in Figure 3.

[0180] In addition, the following method can be used to control the opening of the carrier and the corresponding device group: In the above shutdown scenario, if the load of the basic coverage layer increases and carrier 1 or carrier 2 does not meet the carrier shutdown conditions, then carrier 1 or carrier 2 is turned on, and the associated device group 1 needs to be turned on to meet the normal needs of the service. If carrier 3 and carrier 4 do not meet the carrier shutdown conditions, carrier 3 or carrier 4 needs to be turned on, and the associated device group 2 also needs to be turned on. And so on.

[0181] The following method can be used to intelligently shut down the device group through carrier migration: When an AAU has N device groups and each device group has M carriers, the load conditions of the N device groups and carriers are obtained periodically or in real time. When the loads of the M carriers do not meet the shutdown conditions:

[0182] 1) Analyze the device group with the lowest load. If the load threshold cannot be higher than 20% (the percentage of the current load of the device group and the maximum load it can accommodate), when the difference between the load of other device groups and the load accommodating capacity of the corresponding device group is greater than the load of the device group with the lowest load, migrate the carrier of the device group to other device groups. Figure 3C As shown, Figure 3CA schematic diagram of shutting down the first device group provided in an embodiment of the present application. Device group 1 (i.e., the first device group) is the lowest load device group, corresponding to carrier 1 and carrier 2. When the load carrying capacity of device group 2 (i.e., the limit device load) - device group 2 load (i.e., the current device load) > carrier 1 load and (load carrying capacity of device group 3 - device group 3 load) > carrier 2 load, carrier 1 of device group 1 is migrated to device group 2, carrier 2 of device group 1 is migrated to device group 3, and then device group 1 is shut down to achieve the energy saving benefits brought by shutting down device group 1. The carrier migration process is through the reconfiguration of the carrier and the switching of the associated device groups. The AAU migrates the configuration of carrier 1 from device group 1 to device group 2, so that no carrier is established on device group 1.

[0183] 2) Re-acquire the load of the current device group that is not shut down and the corresponding carrier, and repeat step 1) until the device group cannot be shut down by carrier migration.

[0184] The following method can be adopted to intelligently open the device group through carrier migration: in the above-mentioned shutdown scenario, if the load of carrier 1, carrier 2, carrier 3, carrier 4, carrier 5, and carrier 6 increases, causing the corresponding device group 2 and device group 3 to accommodate a load higher than the migration threshold (for example, set to 60%), then open device group 1 and restore the configuration of carrier 1 and carrier 2 to device group 1 to ensure service performance.

[0185] In addition, the load reduction method may not be limited to carrier migration or service migration. For example, methods such as service release, carrier and device correspondence exchange, etc., all belong to alternative implementation schemes in the present invention. Moreover, the present method does not limit how to select the device group to be shut down. The implementation method provided in the present method is to start polling from the lowest load. Other methods such as sequential polling, random selection, etc. all belong to alternative implementation schemes in the present invention. The load judgment of the device group includes but is not limited to: service PRB (Physical resource blocks) utilization, the number of users of the carrier, etc. The device group mentioned in the present method includes but is not limited to MCS chips, etc. As long as it can be shut down between the channel layer and the carrier layer and bring energy-saving benefits, it belongs to the concept of the present invention. The present invention uniformly uses devices to represent.

[0186] It should be noted that, in addition to the contents recorded above, this embodiment may also include the technical features described in the above embodiments, so as to achieve the technical effects of the base station control method shown above. Please refer to the above description for details. For the sake of brevity, it will not be repeated here.
