Abstract
Description
Technical Field
[0001] This invention relates to the field of communication technology, and in particular to an energy-saving method, apparatus, device, and storage medium for a baseband processing unit (BBU). Background Technology
[0002] In existing communication technologies, energy-saving technologies for next-generation base station equipment (gNodeB, gNB) in wireless communication systems mainly include technologies on the Radio Remote Unit (RRU) / Active Antenna Unit (AAU) side and the Building Baseband Unit (BBU) side. The power consumption on the RRU / AAU side is greatly affected by service load, and current solutions include channel shutdown, carrier shutdown, symbol shutdown, and deep sleep to address energy saving issues on the RRU / AAU side. The power consumption on the BBU side, however, is related to the inserted devices and is less affected by service load compared to the RRU / AAU side. When the RRU / AAU side enters shutdown or sleep mode due to low service load, the power consumption of the BBU baseband board does not decrease significantly.
[0003] BBU-side energy saving reduces power consumption by adjusting the scale of digital logic circuits, chip technology, and configuration. However, these methods are more complex than those that reduce power consumption through software-controlled sleep and wake-up of the baseband board and soft-core modules. Some BBU-side energy saving methods can only reduce power consumption by coordinating with the RF unit to start and stop the entire baseband board. The BBU side cannot achieve dynamic and accurate baseband module sleep mode. In complex network configurations, multiple cells on a single baseband board cannot independently achieve sleep and wake-up; nor can it meet the requirements of dynamic management of cell resources and maintenance of services for connected terminals.
[0004] In summary, the BBU side has the problem of being unable to independently control energy conservation and manage resources within the community. Summary of the Invention

[0050] Before describing the specific embodiments of the present invention, the following will be explained first:
[0051] The main components of a BBU system include the main control circuit, baseband circuit, power supply circuit, synchronization circuit, and fan. Among these, the baseband circuit is the primary source of power consumption in the BBU system. The core of the BBU baseband circuit is an Application Specific Integrated Circuit (ASIC) chip, and its power consumption during operation mainly consists of static power consumption and dynamic power consumption.
[0052] Static power consumption:
[0053] The static power consumption is mainly caused by the leakage current of the ASIC chip. Once the baseband ASIC chip is powered on, static power consumption will inevitably exist regardless of whether there is a baseband protocol stack signal processing task.
[0054] Dynamic power consumption:
[0055] The power consumption is primarily caused by the state transitions of the internal logic circuits of the baseband ASIC chip and the accompanying charging and discharging current. Therefore, the magnitude of dynamic power consumption depends on factors such as the manufacturing process of the baseband ASIC chip and the scale of the digital logic circuits. Given a fixed BBU baseband ASIC chip manufacturing process and operating temperature, reducing power consumption while ensuring a good user experience mainly involves adjusting the scale of the digital logic circuits used, adjusting the chip's clock speed, and adjusting the core voltage swing. Among these measures, adjusting the scale of the digital logic circuits used is the most effective but also the most difficult to implement.
[0056] To address the problem in existing technologies where the BBU (Baseband Processing Unit) cannot independently control energy efficiency and manage resources within a cell, this invention provides an energy-saving method, apparatus, device, and storage medium for a baseband processing unit (BBU).
[0057] like Figure 1 As shown, this embodiment of the invention provides an energy-saving method for a baseband processing unit (BBU). The processor of the BBU includes at least one core, and at least one cell is deployed on one of the cores. The BBU is connected to at least one radio frequency unit, wherein one of the radio frequency units is communicatively connected to at least one of the cells.
[0058] The radio frequency unit includes an AAU and an RRU. In this embodiment of the invention, the RRU is used as an example for illustration.
[0059] For example, the structure of the BBU is as follows Figure 2 As shown, Figure 2 The BBU shown includes three cores: core1, core2, and core3. Core1 has two cells deployed, cell0 and cell1; core2 has two cells deployed, cell2 and cell3; and core3 has one cell deployed, cell4. Each radio frequency unit communicates with one cell: cell0 communicates with RRU0, cell1 communicates with RRU1, cell2 communicates with RRU2, cell3 communicates with RRU3, and cell4 communicates with RRU4.
[0060] Taking a single baseband board with multiple cells as an example, resource integration during cell hibernation can be performed as follows, i.e., the energy-saving methods of the baseband processing unit (BBU) include:
[0061] Step 101: Send first indication information to the first radio frequency unit. The first indication information is used to instruct the first radio frequency unit to enter power saving mode or shutdown mode. The first radio frequency unit is at least one of the radio frequency units.
[0062] It should be noted that due to the diversity of cell types and network configurations supported by base stations, the sleep and wake-up operations of each cell on each core need to be managed separately.
[0063] In this step, the BBU notifies some AAU / RRUs (i.e., the first radio frequency unit) to enter power-saving mode or shutdown mode via the first indication information. The first radio frequency unit then enters power-saving mode or shutdown mode according to the first indication information. For example, the BBU sends... Figure 2 RRU0 and RRU1, as shown, send a first instruction message, and RRU0 and RRU1 enter either energy-saving mode or shutdown mode according to the first instruction message.
[0064] Step 102: Allocate the first allocation resource to the second cell, or deploy the cell on the first kernel according to the first allocation resource; wherein, the first allocation resource is the allocation resource of the first cell that the first radio frequency unit communicates with; the second cell is a cell other than the first cell, and the first kernel is a kernel different from the kernel to which the first cell belongs.
[0065] The second cell is any cell other than the first cell among all cells where the BBU processor kernel is deployed.
[0066] In this step, after releasing the first allocated resource of the first cell, the BBU's RRM traverses the non-dormant cells (i.e., the second cell) and allocates the first allocated resource to the second cell.
[0067] or,
[0068] After releasing the first allocated resources of the first cell, the BBU traverses the non-dormant kernels, determines the first kernel other than the kernel to which the first cell belongs, and reallocates the first allocated resources to the first kernel. The cell is then re-established on the first kernel, and the previously occupied cell resources (i.e., the first allocated resources) are released.
[0069] It should be noted that during this process, terminals already connected to the cell to be migrated (i.e., the first cell) will be moved to other non-dormant cells (i.e., the second cell) to ensure that their service processes are not affected. Specifically, before the core resources of the cell are reallocated and the cell is re-established, the connected terminals will be migrated to other non-dormant cells through reselection and handover.
[0070] Step 103: Release the first allocated resources of the first cell in which the first radio frequency unit communicates.
[0071] The BBU notifies the Radio Resource Management (RRM) of Layer 3 (L3) via Layer 2 (L2) / Layer 1 (L1) to delete the resources allocated to the cell (i.e., the first cell) that the AAU / RRU (i.e., the first radio unit) is communicating with (i.e., the first allocated resources).
[0072] For example, Figure 2 After RRU0 and RRU1 enter the energy-saving mode or shutdown mode according to the first instruction information, the resources allocated to cell0, which is connected to RRU0, and cell1, which is connected to RRU1, are released.
[0073] The first allocation of resources includes Media Access Control (MAC) resources, Radio Link Control (RLC) resources, and RRM resources.
[0074] That is, after the BBU sends an instruction to the AAU / RRU to enter power-saving mode or shutdown mode, it releases the MAC, RLC, and RRM resources of all corresponding cells in sequence.
[0075] The above steps of the present invention dynamically allocate the baseband module resources required by the cell by using the BBU protocol stack processor soft core hibernation method, and start or stop the use of the corresponding baseband module, thereby realizing software-hardware collaborative BBU energy-saving management.
[0076] In an optional embodiment, the method further includes:
[0077] After all the allocated resources of the cell on the second core are released, the first core is put into hibernation.
[0078] The second core is at least one core within the processor of the BBU.
[0079] When the BBU notifies the RRU to enable power-saving measures, it also puts the BBU-side processor into hibernation, releasing and integrating cell resources, allowing cores without cell resource occupancy (i.e., secondary cores) to proactively enter hibernation. This effectively reduces power consumption for the BBU under low service load conditions. Specifically, the BBU notifies the driver layer that soft cores no longer occupying cell resources will enter hibernation.
[0080] In an optional embodiment, the method further includes:
[0081] When all the cores contained in the processor of the BBU are in hibernation, control the BBU to hibernate.
[0082] In other words, after all the soft cores on the baseband board of the BBU enter a sleep state, the driver layer is notified to put the baseband board device into sleep mode.
[0083] In an optional embodiment, allocating the first allocation resource to the second cell includes:
[0084] Among the cells deployed on the kernel, a second cell with the same resource configuration information as the first cell is identified;
[0085] The first allocated resources are allocated to the second cell.
[0086] The resource configuration information includes at least one of the following:
[0087] Uplink and downlink bandwidth of the cell;
[0088] Number of channels;
[0089] User capacity.
[0090] The BBU's RRM traverses the non-dormant cells. If a cell with the same resource configuration exists, such as a cell with the same uplink / downlink bandwidth, number of channels, user capacity, etc., the cell is treated as the second cell, and the first allocation resources are reallocated to the non-dormant second cell of the same specification.
[0091] In one optional embodiment, deploying a cell on a first kernel according to a first allocated resource includes:
[0092] Among the at least one core, the fourth core that is not in sleep mode among the third cores other than the core to which the first cell belongs, i.e. the non-sleep core that does not exist on each core of the BBU integrated baseband board, is the fourth core.
[0093] The kernel in the fourth kernel that can carry the first allocated resources is determined to be the first kernel. Specifically, the kernel in the fourth kernel that can carry the first allocated resources is determined to be the kernel that can re-establish the cell. If there are multiple kernels, any kernel in the multi-core kernel is randomly selected as the first kernel.
[0094] Based on the first allocated resources, a cell is deployed on the first kernel, that is, a cell is re-established on the first kernel, releasing the first allocated resources previously occupied by the first cell.
[0095] In an alternative embodiment, the method further includes at least one of the following:
[0096] Send a second indication message to the first radio frequency unit, deploy a third cell on the kernel to which the first cell belongs, and allocate resources to the third cell. The second indication message is used to instruct the first radio frequency unit to exit the power saving mode or exit the shutdown mode.
[0097] When the first radio frequency unit exits power-saving mode or exits shutdown mode, a third cell is deployed on the kernel to which the first cell belongs, and resources are allocated to the third cell.
[0098] In one embodiment, after the first radio frequency unit (AAU / RRU) is passively woken up and accesses the BBU, the kernel corresponding to the first radio frequency unit (i.e., the kernel to which the first cell of the communication connection belongs) is woken up, and cell establishment (deploying the third cell) is re-performed in the kernel to restore normal service status. Here, passive wake-up means that the BBU sends a second indication information to the first radio frequency unit, which is used to instruct the first radio frequency unit to exit the power-saving mode or exit the shutdown mode. In another embodiment, after the first radio frequency unit (AAU / RRU) is actively woken up and accesses the BBU, the kernel corresponding to the first radio frequency unit (i.e., the kernel to which the first cell of the communication connection belongs) is woken up, and cell establishment (deploying the third cell) is re-performed in the kernel to restore normal service status.
[0099] Specifically, the BBU determines whether the conditions for exiting various energy-saving schemes are met and notifies the AAU / RRU to exit energy-saving mode or shutdown mode. Alternatively, the AAU / RRU exits energy-saving mode or shutdown mode by periodically waking itself up. After exiting energy-saving mode, the AAU / RRU notifies the BBU to wake up the processor core that is in hibernation on the baseband board. After the baseband board core exits hibernation, it reallocates protocol stack cell resources and re-establishes the cell. The cell can then perform normal services, enabling the BBU-side cell to quickly return to normal service status.
[0100] In an optional embodiment, before sending the first indication information to the first radio frequency unit, the method further includes:
[0101] Obtain the resources allocated by the BBU to each cell;
[0102] Based on the resources allocated to each cell, the allocated resources corresponding to the cells are integrated to determine the first cell for which resources need to be released;
[0103] The radio frequency unit that the first cell communicates with is identified as the first radio frequency unit.
[0104] In this optional embodiment, the BBU obtains the resources allocated to each cell, integrates the resources on the kernel of each cell based on the allocated resources, determines the first cell whose resources need to be released, and then determines the radio frequency unit of the communication connection of the first cell as the first radio frequency unit. For example, it can... Figure 2The five cells in the middle are redeployed into four cells. Specifically, cell4, which is connected to RRU4, can be redeployed into core1, which belongs to cell2. Then cell4 is determined to be the first cell, and RRU4, which is connected to cell4, is the first radio frequency unit.
[0105] It should be noted that the power consumption of the processor cores containing modules such as the platform layer, drivers, OAM, protocol stack-managed RRM, managed MAC, and RLC on the BBU processor is relatively unaffected by traffic volume. After the RF unit AAU / RRU meets the conditions for entering power-saving mode, the power consumption of the protocol stack's soft core will not decrease significantly with reduced traffic, resulting in excess power consumption on the baseband board. Therefore, when the power-saving conditions are met on the RF unit side, it is advisable to put the processor soft core of the power-saving cell into sleep mode to reduce power consumption. This allows for precise module-level and cell-level sleep mode implementation of power reduction on the BBU unit side.
[0106] Due to the diversity of cell standards and network configurations supported by base stations, sleep and wake-up operations need to be managed separately for each cell on each core. If a processor core becomes idle due to a cell entering sleep mode, freeing up cell resources, these resources are reallocated to an active cell of the same specification. The cell resources are migrated by adding inter-layer signaling messages, releasing the previously occupied cell resources and core, thereby maximizing the energy efficiency of the BBU system baseband board.
[0107] In summary, considering the baseband hardware resources required under different business conditions, unused baseband module circuits can be statically or dynamically shut down, thereby saving BBU system power consumption. Simultaneously, the software can dynamically allocate the required baseband module resources based on changes in business dynamics, starting or stopping the use of corresponding baseband modules to maximize BBU system energy saving without affecting business load and user experience. This invention can solve the device hibernation problem at the cell and module levels on the baseband unit, ensuring that a single cell can independently achieve hibernation and wake-up, accurately reducing power consumption; 2. It solves the dynamic management problem of cell resources during soft core hibernation, effectively integrating cell resources during the hibernation process of the baseband soft core, ensuring stable business operations in non-hibernating cells while maximizing the utilization efficiency of soft core resources; 3. It avoids the problem of accessing terminals on this site being affected by cell resource adjustments. This can affect normal business processing. By implementing a method of BBU protocol stack processor soft core hibernation on the BBU side of the base station system, the baseband module resources of the cell can be effectively controlled and allocated, improving the accuracy and flexibility of BBU processor energy saving. This enables BBU energy saving management through software logic in collaboration with hardware. Based on various energy-saving schemes in collaboration with AAU / RRU, BBU hibernation and exit-from-hibernation processes are managed to ensure consistency in energy-saving process management and improve the overall energy efficiency of the base station. Without affecting service load and user experience, the required baseband module resources can be dynamically allocated, and the use of corresponding baseband modules can be started or stopped, ensuring that while maximizing BBU system energy saving, normal business operations are not affected.
[0108] like Figure 3 As shown, this embodiment of the invention also provides an energy-saving device for a baseband processing unit (BBU). The processor of the BBU includes at least one core, and at least one cell is deployed on one of the cores.
