[0064] The embodiments of the present disclosure are not limited to the embodiments shown in the drawings, but include modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings are schematic in nature, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.
[0065] First, refer to Figure 1 , an embodiment of the present disclosure provides a method for shutting down a base station channel, comprising:
[0066] S101: Obtain operating status information of a base station.
[0067] The device for controlling the base station channel shutdown (such as a server) obtains the current operating status information of the running base station, such as the current traffic volume of the base station.
[0068] S102: If the operating status information satisfies a preset first condition, shut down at least some channels of the base station according to the operating status information.
[0069] After receiving the operating status information of the base station, the server judges the operating status information to determine whether it meets the first condition, wherein the first condition is a preset condition, and different first conditions can be set for different base stations according to actual conditions.
[0070] If the first condition is met, the base station channels that need to be shut down are determined based on the operating status information and shut down. The base station channels that need to be shut down will obviously be different depending on the base station's operating status. For example, the number of base station channels that need to be shut down will obviously be different depending on the base station's traffic volume.
[0071] In some related technologies, fixed base station channels are shut down during certain time periods (such as normal service idle periods). However, the actual base station traffic does not always change according to a time pattern. Therefore, shutting down the base station channels during fixed time periods may cause the base station channels to be shut down incorrectly when the base station traffic is large, affecting the service quality of the base station and the user experience, or failing to shut down the channels when the traffic is small, which fails to fully save energy.
[0072] Compared to shutting down fixed base station channels, when the base station's traffic volume is high, the base station channel shutoff method of the disclosed embodiment shuts down fewer base station channels based on operating status information to ensure base station service quality. When the base station's traffic volume decreases, the base station channel shutoff method of the disclosed embodiment, after judging based on operating status information, shuts down more base station channels, saving more energy. Therefore, the base station channel shutoff method of the disclosed embodiment shuts down base station channels based on the base station's operating status information. Different operating status information corresponds to different channels being shut down, fully utilizing the service tidal effect and providing strong flexibility.
[0073] Reference Figure 2 In some embodiments, if the operating status information satisfies a preset first condition, shutting down at least part of the channels of the base station according to the operating status information (S102) includes: within a preset time period, if the operating status information satisfies the preset first condition, shutting down at least part of the channels of the base station according to the operating status information.
[0074] If the current time is not within the preset time period, even if the base station's operating status information meets the first condition, the base station channel will not be shut down, or the server only obtains the base station's operating status information and makes a judgment within the preset time period.
[0075] This is because it may be accidental that the operating status information (such as business volume) of some base stations set up in special areas (such as busy areas) is lower than the threshold value at some time points (such as during the day). The operating status information (such as business volume) of the base station is likely to exceed the threshold value soon. If the base station channel is shut down, it is likely to affect the user experience. In order not to continue to affect the user experience, the base station channel that has just been shut down may need to be opened immediately. Frequent opening and closing of the base station channel will affect the energy saving effect. Therefore, the operating status information of the base station is only obtained and judged within a preset time period (such as at night), which reduces the impact on the user experience.
[0076] Reference Figure 2 In some embodiments, the operation status information includes at least one of the traffic volume of the base station, the power of the base station, the utilization rate of the physical resource blocks of the base station, and the number of terminals connected to the base station;
[0077] The first condition includes at least one of the following:
[0078] The traffic volume of the base station is lower than the preset traffic shut-off threshold;
[0079] The power of the base station is lower than the preset shutdown power threshold;
[0080] The physical resource block utilization rate of the base station is lower than the preset physical resource block utilization rate threshold;
[0081] The number of terminals connected to the base station is lower than the preset shutdown terminal number threshold.
[0082] The operating status information of the base station acquired by the server may include the traffic volume of the base station, the power of the base station, the PRB (Physical Resource Block) utilization rate of the base station, and the number of terminals connected to the base station.
[0083] Among them, the business volume of the base station refers to the total amount of various businesses carried out by the base station and terminals and other equipment. When the business volume of the base station is large, or the business is busy, the base station channels may all carry business and the carried business volume may be close to its business volume limit. At this time, if some channels of the base station are shut down, it will have a greater impact on the base station business, which may cause a huge decline in user experience; when the business volume of the base station is small, or the business is relatively idle, some channels of the base station may not carry business or the business volume carried by the channels of most base stations is far from the channel limit. Therefore, shutting down some base station channels has little impact on the base station business and the user experience.
[0084] Base station power refers to the power used to transmit and receive wireless signals. The transmission and reception of wireless signals by a base station is essentially the service process between the base station and devices such as terminals. Therefore, similar to the base station's traffic volume, when base station power is high, most base station channels may be carrying services, and the traffic volume carried may be close to their capacity limit. When base station power is low, some base station channels may not be carrying services, or the traffic volume carried by most base station channels may be significantly below the channel capacity limit. Therefore, when base station power is low, shutting down some base station channels will have a smaller impact on base station services and the user experience.
[0085] Base station PRB utilization refers to the utilization rate of 12 consecutive carrier resources in the base station's frequency domain. A higher base station PRB utilization indicates more carrier resources are used by the base station, which in turn means more base station channels are used, or more services are carried by each base station channel. A lower base station PRB utilization indicates fewer carrier resources are used by the base station, which in turn means fewer base station channels are used, or fewer services are carried by each base station channel. Therefore, when a base station's PRB utilization is low, shutting down some base station channels will have less impact on base station services and the user experience.
[0086] As the name suggests, the number of terminals connected to the base station refers to the number of terminals conducting business with the base station. The more terminals conducting business with the base station, the more base station channels are obviously needed to carry the business or each base station channel needs to carry more business; the fewer terminals conducting business with the base station, the fewer base station channels are needed to carry the business or each channel needs to carry less business; therefore, when the number of terminals connected to the base station is small, shutting down some base station channels will have less impact on the base station business and the user experience.
[0087] These parameters can well reflect the current business busyness of the base station and the occupancy of the base station channels.
[0088] After obtaining the above-mentioned operating status information (i.e., the base station's business volume, the base station's power, the base station's PRB utilization, and the number of terminals connected to the base station), the server determines whether the operating status information meets the first condition. The first condition can specifically be that a specific value of the obtained operating status information is lower than the corresponding preset shutdown threshold value, such as the base station's business volume is lower than the preset shutdown business volume threshold value or the base station's power is lower than the preset shutdown power threshold value or the base station's physical resource block utilization rate is lower than the preset shutdown physical resource block utilization rate threshold value or the number of terminals connected to the base station is lower than the preset shutdown terminal number threshold value.
[0089] If the base station is a 64-antenna base station, the first condition is met if one of the following conditions is met, and some channels of the base station can be shut down:
[0090] 1. The traffic volume of the base station is lower than the preset traffic shutoff threshold.
[0091] 2. The power of the base station is lower than the preset shutdown power threshold.
[0092] 3. The PRB utilization rate of the base station is lower than the preset physical resource block utilization rate threshold.
[0093] 4. The number of terminals connected to the base station is lower than the preset shutdown terminal number threshold.
[0094] At this time, the business volume of the base station can be obtained first. If the business volume of the base station is lower than the threshold value for shutting down the business volume, it can be directly considered that the first condition has been met. There is no need to obtain other operating status information and some base station channels can be directly shut down according to the business volume of the base station; if the business volume of the base station is higher than the threshold value for shutting down the business volume, continue to obtain other operating status information (such as the power of the base station, etc.) and make a judgment.
[0095] The first condition may also be that multiple specific values of the acquired operating status information are lower than corresponding preset threshold values.
[0096] If the base station operating status information meets at least two of the following conditions, the first condition is considered to be met and some channels of the base station can be shut down:
[0097] 1. The traffic volume of the base station is lower than the preset traffic shutoff threshold.
[0098] 2. The power of the base station is lower than the preset shutdown power threshold.
[0099] 3. The PRB utilization rate of the base station is lower than the preset physical resource block utilization rate threshold.
[0100] 4. The number of terminals connected to the base station is lower than the preset shutdown terminal number threshold.
[0101] Alternatively, you can set a certain weight for each condition (such as condition 1 has a weight of 30, condition 2 has a weight of 25, condition 3 has a weight of 30, and condition 4 has a weight of 15), add up the weights of the conditions that are met to obtain a score (such as if conditions 1 and 3 are met, the score is 60). If the score meets certain conditions (such as greater than or equal to 60), it is considered that the first condition is met.
[0102] Of course, the first condition may also be that all specific values of the acquired operating status information are lower than corresponding preset thresholds.
[0103] The first condition is considered met only when the base station operating status information meets all of the following conditions, and only then can some channels of the base station be shut down:
[0104] 1. The traffic volume of the base station is lower than the preset traffic shutoff threshold.
[0105] 2. The power of the base station is lower than the preset shutdown power threshold.
[0106] 3. The PRB utilization rate of the base station is lower than the preset physical resource block utilization rate threshold.
[0107] 4. The number of terminals connected to the base station is lower than the preset shutdown terminal number threshold.
[0108] Different threshold values and first conditions can be flexibly set for different base stations. For example, if a base station mainly carries out important services, its threshold value can be set to a lower value, and the first condition can be set to a more stringent condition (such as all specific values of the obtained operating status information are lower than the corresponding preset threshold value).
[0109] Reference Figure 2 In some embodiments, after obtaining the operating status information of the base station (S102), the following steps are further included:
[0110] S103: If the operation status information satisfies a preset second condition, all channels of the base station are opened.
[0111] The second condition includes at least one of the following:
[0112] The service volume of the base station exceeds the preset restart service volume threshold;
[0113] The power of the base station is higher than the preset restart power threshold;
[0114] The physical resource block utilization rate of the base station is higher than the preset restart physical resource block utilization rate threshold;
[0115] The number of terminals connected to the base station exceeds the preset restart terminal number threshold;
[0116] The restart traffic volume threshold is higher than the shutdown traffic volume threshold; the restart power threshold is higher than the shutdown power threshold; the restart physical resource block utilization threshold is higher than the shutdown physical resource block utilization threshold; the restart terminal number threshold is higher than the shutdown terminal number threshold.
[0117] After obtaining the operating status information of the base station, if the server determines that the operating status information no longer meets the preset first condition, it will immediately open all channels of the base station. When the operating status information of the base station jumps near the first condition, it is easy for the base station channels to be frequently opened and closed (i.e., the ping-pong effect).
[0118] If the first condition is that the base station's business volume is lower than the preset shut-down business volume threshold, and the base station's business volume fluctuates around the shut-down business volume threshold, the base station's business volume obtained at the current moment may be lower than the preset shut-down business volume threshold, and some base station channels need to be shut down. The base station's business volume obtained at the next moment may be higher than the preset shut-down business volume threshold, and all base station channels need to be opened, resulting in frequent shutting down and opening of base station channels.
[0119] In order to avoid this situation, the base station channel shutdown method of the embodiment of the present disclosure sets a restart threshold value corresponding to the shutdown threshold value (i.e., the shutdown traffic volume threshold value, the shutdown power threshold value, the shutdown physical resource block utilization threshold value, and the shutdown terminal number threshold value), that is, the restart traffic volume threshold value corresponding to the shutdown traffic volume threshold value, the restart power threshold value corresponding to the shutdown power threshold value, the restart physical resource block utilization threshold value corresponding to the shutdown physical resource block utilization threshold value, and the restart terminal number threshold value corresponding to the shutdown terminal number threshold value, and each restart threshold value is higher than the corresponding shutdown threshold value. When the operating status information of the base station exceeds the shutdown threshold value but does not exceed the restart threshold value, not all base station channels are opened, but wait until the operating status information of the base station exceeds the restart threshold value before opening all base station channels. For example, when the traffic volume of the base station exceeds the shutdown traffic volume threshold value, not all base station channels are opened, but wait until the traffic volume of the base station exceeds the restart traffic volume threshold value before opening all base station channels.
[0120] Since the restart threshold value is higher than the shutdown threshold value, the channel will only be restarted when the base station's operating status information is higher than the shutdown threshold value to a certain extent. Since the base station's operating status information has obviously exceeded the shutdown threshold value when restarting, in most cases, the base station's operating status information will not become lower than the shutdown threshold value again in a short time, thereby avoiding frequent shutdown and opening of the base station channel in a short time.
[0121] Of course, if the remaining base station channels are in an abnormal state after some base station channels are shut down, or the time is no longer within the preset time period, the base station channels may no longer be shut down and the shut-off base station channels may be restarted.
[0122] Reference Figure 3 In some embodiments, if the operating status information satisfies a preset second condition, opening all channels of the base station (S103) includes: when the time from the last step of shutting down at least part of the channels of the base station according to the operating status information exceeds a predetermined time, if the operating status information satisfies the preset second condition, opening all channels of the base station.
[0123] In order to avoid the ping-pong effect, a timer can also be set while shutting down the base station channel. Before the timer is shut down, even if the operating status information of the base station does not meet the first condition, the shut-off base station channel will not be reopened, thereby ensuring that the base station channel will not be reopened within the time period when the timer is not shut down after being shut down (that is, the channel will not be reopened within a short time after being shut down).
[0124] Of course, if the remaining base station channels are in an abnormal state after some base station channels are shut down, or the time is no longer within the preset time period, the base station channels may no longer be shut down and the shut-off base station channels may be restarted.
[0125] Similarly, a timer is set when the base station channel is reopened. Before the timer is turned off, the base station channel will not be turned off even if the operating status information of the base station meets the first condition. This ensures that the base station channel will not be turned off again within the time period after it is opened, thereby avoiding the base station channel being frequently opened and closed in a short period of time.
[0126] Reference Figure 3 In some embodiments, the operation status information includes at least one of a traffic volume of the base station, a power of the base station, a physical resource block utilization rate of the base station, and an energy consumption of the base station when different numbers of channels are shut down;
[0127] Shutting down at least part of the channels of the base station according to the operation status information (S102) includes:
[0128] S1021. Determine the number of channels of the base station to be shut down according to at least one of the traffic volume of the base station, the power of the base station, the physical resource block utilization rate of the base station, and the energy consumption of the base station when shutting down different numbers of channels.
[0129] After determining that the operation status information satisfies the first condition, the server adaptively determines the number of base stations that need to be shut down according to different operation status information.
[0130] For example, if the PRB utilization of the base station is recorded periodically, considering the fluctuation of the operation status information, the recorded PRB utilization of the base station is filtered using the following formula to obtain the filtered PRB utilization.
[0131] PRB utilization 滤波(n) = α × PRB utilization rate (n) + (1-α) × PRB utilization rate 滤波 (n-1)
[0132] Among them, PRB utilization 滤波 (n-1) is the PRB utilization rate of the base station obtained by the n-1th filtering, PRB utilization rate (n) is the PRB utilization rate of the base station recorded for the nth time, and PRB utilization rate 滤波 (n) is the PRB utilization rate of the base station obtained by the nth filtering, and α is the filtering smoothing factor, which can be set manually according to the actual situation or obtained through data learning.
[0133] PRB utilization rate obtained by filtering 滤波 Different values of (n) shut down different numbers of channels. If the PRB utilization rate obtained by filtering is 滤波 (n) is less than the first threshold set, then all channels of the base station are shut down. (Refer to Figure 4 ), if the PRB utilization rate obtained by filtering 滤波 (n) is less than the set second threshold, then all channels of the base station are shut down. (Refer to Figure 5 ), if the PRB utilization rate obtained by filtering 滤波 (n) is less than the third threshold, then all channels of the base station are shut down. (Refer to Figure 6 ).
[0134] Figures 4 to 6 In the figure, each intersection position represents two channels (channel numbers are represented by P0 to P63, that is, the figure shows a total of 64 channels for the base station), and the intersection position surrounded by a dotted frame and outlined in bold in the figure represents a turned-off channel.
[0135] Of course, the number of shut-off channels can also be determined in a similar way based on the traffic volume and power of the base station. The number of shut-off channels can also be determined by comprehensively considering the traffic volume, power and PRB utilization of the base station, such as giving different weights to the traffic volume, power and PRB utilization of the base station.
[0136] Since the number of base station channels shut down is not linearly related to the energy consumption of the base station, the energy consumption changes of the base station when different numbers of base station channels are shut down can be considered based on the base station operation status information to make a judgment, such as shutting down all base station channels. Although it is better than shutting down all base station channels Energy consumption will be 30% higher, but the traffic volume that each base station channel that is not shut down needs to carry will be 70% higher. Therefore, comprehensive consideration is needed.
[0137] By shutting down different numbers of channels according to different operating status information of the base station, the best energy-saving effect can be achieved with minimal impact on the base station business.
[0138] Reference Figure 3 In some embodiments, the operating status information includes at least one of a degree of matching between a beam weight of the base station and current terminal channel information when channels at different locations are shut down, and energy consumption of the base station when channels at different locations are shut down;
[0139] Shutting down at least part of the channels of the base station according to the operation status information (S102) includes:
[0140] S1022. Determine the location of the channel to be shut down based on at least one of the degree of matching between the beam weight of the base station and the current terminal channel information when shutting down the channels at different locations, and the energy consumption of the base station when shutting down the channels at different locations.
[0141] After determining that the operation status information meets the first condition, the server adaptively determines the location of the base station that needs to be shut down according to different operation status information (such as the matching degree between the beam weight of the base station and the current terminal channel information when shutting down the channels at different locations), such as the line shutdown (refer to Figure 5 ), column shutdown (refer to Figure 6 ), block shutdown (refer to Figure 4 ).
[0142] Among them, rows and columns refer to the rows and columns arranged by channels in the antenna array of the base station, that is, Figure 4 、 5 、6 in the rows and columns. Figures 4 to 6 In the figure, each intersection position represents two channels (channel numbers are represented by P0 to P63, that is, the figure shows a total of 64 channels for the base station), and the intersection position surrounded by a dotted frame and outlined in bold in the figure represents a turned-off channel.
[0143] Shutting off channels at different locations will cause the beam weight of the base station to change. The terminal communicates with the base station through the beam. The services of terminals at different locations are handled by different beams. Therefore, it is necessary to determine the required beam weight based on the location of the terminal currently performing the service, and further determine the location of the channel to be shut down.
[0144] For example, the channel matrix of the terminal device measured by the base station is correlated with the beam weights when shutting down channels at different positions, and the shut-down channels corresponding to the beam weights with greater correlation are shut down first.
[0145] If the current service of the base station is mainly for terminals in a building, because the channels of different rows of the base station can cover areas within different height ranges, when the column base station channels are turned off, the beam weight is more correlated with the channel matrix of the terminal equipment. Therefore, multiple columns of the base station channels can be turned off, leaving some columns of base station channels. If the current service of the base station is mainly for terminals in a region, because different columns of the base station can cover different plane areas, when the row base station channels are turned off, the beam weight is more correlated with the channel matrix of the terminal equipment. Therefore, multiple rows of base station channels can be turned off, leaving some rows of base station channels.
[0146] Although the number of shutoff channels remains the same, the energy consumption of base stations may vary when shutting down channels at different locations. Therefore, it is important to consider not only the compatibility of the shutoff channel locations with the current base station service, but also the energy consumption of the base station when shutting down channels at different locations. For example, when shutting down base station channels in the same column direction, the energy consumption will vary depending on the column. If both columns can meet the current service requirements, shutting down columns with higher energy consumption will obviously save more base station energy.
[0147] By shutting down channels at different locations according to the different operating status information of the base station, the best energy-saving effect can be achieved with minimal impact on the base station business.
[0148] Reference Figure 3 In some embodiments, the operation status information includes at least one of an uplink channel signal-to-noise ratio, energy consumption of the base station when the downlink channel is shut down, and energy consumption of the base station when both the uplink channel and the downlink channel are shut down;
[0149] Shutting down at least part of the channels of the base station according to the operation status information (S102) includes:
[0150] S1023. Determine whether to shut down the downlink channel of at least part of the channels of the base station or shut down both the uplink channel and the downlink channel of at least part of the channels of the base station based on at least one of the signal-to-noise ratio of the uplink channel, the energy consumption of the base station when the downlink channel is shut down, and the energy consumption of the base station when both the uplink channel and the downlink channel are shut down.
[0151] After determining that the operation status information satisfies the first condition, the server adaptively determines to shut down only the downlink channels of some channels of the base station or shut down both the uplink channels and the downlink channels of some channels of the base station according to different operation status information.
[0152] Downlink refers to the base station actively sending signals to the terminal, which is a transmission process for the base station, so the downlink channel consumes more energy. Uplink, on the other hand, refers to the base station receiving signals from the terminal, which is only a reception process for the base station, so the uplink channel consumes less energy. Therefore, if conditions permit, both the uplink and downlink channels can be shut down to further save energy. However, if only one of the uplink or downlink channels can be shut down, only the downlink channel is usually shut down, and the uplink channel is not shut down separately.
[0153] Specifically, if the signal-to-noise ratio of the signal (uplink signal) from the terminal received by the current base station is low and below the threshold, it means that the base station cannot receive the uplink signal from the terminal well, so the uplink channel cannot be shut down (otherwise the signal-to-noise ratio will be further reduced), and only the downlink channel can be shut down.
[0154] If the signal-to-noise ratio of the signal from the terminal received by the current base station is high and exceeds the threshold, it means that the base station can receive the uplink signal well, and thus it is possible to shut down the uplink channel. Therefore, it is possible to further determine how to shut down the channel based on the power consumption of the base station when shutting down both the uplink and downlink channels at the same time, and when only shutting down the downlink channel (that is, whether to shut down the uplink channel as well is determined based on whether the additional energy-saving effect is obvious when shutting down the uplink channel).
[0155] Reference Figure 3 In some embodiments, after shutting down at least part of the channels of the base station according to the operating status information (S102), the method further includes:
[0156] S1024. Increase the power spectrum density of the non-disabled channels in the base station;
[0157] and / or,
[0158] The beam weights are set based on the channels that are not shut down in the base station.
[0159] After the server shuts down some channels of the base station based on the operating status information, these channels may have previously carried services. These services cannot be discarded but need to be transferred to other channels. In order to meet the needs of the newly added services, the power spectrum density of the channels that are not shut down needs to be increased.
[0160] While increasing the power density spectrum of the remaining channels, it is also necessary to prevent the power of a single channel from exceeding the rated power (for example, by limiting the number of scheduled PRBs). For example, the power spectrum density of the remaining channels can be increased by 3dB, while limiting the maximum number of scheduled PRBs to half the maximum bandwidth to ensure that the maximum generated power of each channel does not exceed the rated power.
[0161] The beam weights for the remaining channels can also be recalculated based on the number and location of the shut-down channels. The principle of weight calculation should be to keep the beam coverage close to that before the shutdown. This ensures that the service between the terminal and the base station is minimally affected.
