Background Art

[0003] Currently, the energy saving of 5th Generation Mobile Communication Technology (5G) base stations includes site-level energy saving and network-level energy saving. Site-level energy saving includes deep sleep, cell shutdown, symbol shutdown, channel shutdown, and power optimization, etc. Network-level energy saving is to predict the network load based on the performance indicators of all communication cells in a certain area, determine the energy-saving cells and energy-saving strategies by combining the network quality of the area, and implement energy saving on the energy-saving cells by combining with site-level energy-saving means. With the steady progress of 5G network construction, realizing energy saving and emission reduction of 5G base stations not only contributes to cost reduction in operation, but also becomes an important driving force for promoting the green upgrade of products in the communication industry.

[0004] The energy-saving effect of related deep sleep energy-saving solutions is insufficient.

[Brief explanation of the drawing]

[0008] [Figure 1] This is a flowchart of the base station control method provided by the embodiment of the present invention. [Figure 2] This is a compositional block diagram of an electronic device provided by another embodiment of the present application. [Modes for carrying out the invention]

[0009] To better understand the technical proposal of this application, the base station control method, electronic equipment, and computer-readable storage medium provided by this application will be described in detail below with reference to the drawings.

[0010] The following describes exemplary embodiments with reference to the drawings, but these exemplary embodiments may be embodied in different examples and should not be construed as being limited to the embodiments described herein. The purpose of providing these embodiments is to make the present application thoroughly complete and to enable those skilled in the art to fully understand the scope of the present application.

[0011] The various embodiments and features of the present invention can be combined with one another, as long as they do not contradict each other.

[0012] As used in this application, the terms "and / or" include any or all combinations of at least one related enumeration item.

[0013] The terms used herein are for the purpose of describing specific embodiments and are not intended to limit this application. The singular forms “one” and “the said” as used herein are also intended to include the plural form unless otherwise evident from the context. It will be further understood that when the terms “includes” and “consist of” are used herein, they specify the presence of such features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of at least one other feature, whole, step, operation, element, component, and / or group thereof.

[0014] All terms used herein (including technical and scientific terms) shall, unless otherwise specified, have the same meaning as those generally understood by those skilled in the art. Furthermore, it will be understood that such terms, as defined in common dictionaries, shall have the same meaning as in the context of the relevant technical invention and this application, and shall not be interpreted as having an idealized or overly formal meaning unless explicitly defined herein.

[0015] Current base station energy saving technologies include energy saving at the equipment level, site level, and network level. Equipment-level energy saving is mainly achieved through hardware design, while site-level energy saving is mainly achieved by identifying network conditions to ensure network quality and terminal experience. From a software energy saving perspective, precise energy saving is achieved by means of turning off certain equipment, cells, channels, or power amplifiers at appropriate times, such as deep sleep, cell shutdown, symbol shutdown, channel shutdown, and power optimization. Network-level energy saving is achieved from the perspective of multi-network coordination. The main idea is to utilize the business information of the current network, determine network energy saving setting parameters using corresponding intelligent algorithms, and achieve software energy saving for cells. Here, the intelligent algorithm can not only be used to initialize cell parameter settings, but can also make business predictions based on the cell's historical business data and adjust the cell's energy saving strategy accordingly.

[0016] In locations such as shopping malls, campuses, hospitals, parks, office buildings, subway stations, bus terminals, and train stations, there are typically morning and evening rush hours, tidal phenomena are observed, and while the number of users increases sharply during the day, it decreases, and in some cases disappears, at night. Under these circumstances, if base stations operate idle, a huge amount of power is wasted, which is not only contrary to the interests of telecommunications carriers but also does not conform to the global trend of energy conservation and emission reduction in a low-carbon economy. Therefore, the fact that current base stations operate 24 hours a day and cannot conserve energy is an unacceptable reality for telecommunications carriers. Based on the above reasons, telecommunications carriers are incorporating energy conservation and consumption reduction requirements into base station system specifications and are requesting base station system vendors to implement multiple energy conservation strategies and apply different energy conservation strategies to different scenarios. Thus, in locations where tidal phenomena occur at base stations, by shutting down all or part of the service cells and high-power consumption equipment at the base station during times when there are no or few users, energy conservation and consumption reduction can be achieved, thereby enhancing the competitiveness of base station products, reducing the operating costs of telecommunications carriers, and making a beneficial contribution to energy conservation and emission reduction.

[0017] Figure 1 is a flowchart of the base station control method provided by an embodiment of the present invention.

[0018] In the first embodiment, referring to Figure 1, the present embodiment provides a base station control method comprising the following steps 100.

[0019] In step 100, if the energy-saving conditions are met, the multimode baseband processing unit within the Active Antenna Unit (AAU) is controlled to turn off the remote radio unit of the AAU and switch to energy-saving mode. Here, after the multimode baseband processing unit has switched to energy-saving mode, it loads only the first module necessary to ensure normal communication between the Building Baseband Unit (BBU) and the AAU.

[0020] In some exemplary cases, after a multimode baseband processing unit enters energy-saving mode, it does not load the second module of the multimode baseband processing unit, except for the first module.

[0021] In some exemplary embodiments, after controlling the multimode baseband processing unit of the AAU to transition to an energy-saving mode, the method further comprises the step of controlling the multimode baseband processing unit to transition to an operating mode if operating conditions are met. Here, the multimode baseband processing unit loads all modules of the multimode baseband processing unit after transitioning to an operating mode.

[0022] In some exemplary embodiments, the multimode baseband processing unit may be a multimode baseband chip.

[0023] In some exemplary embodiments, the operating scenes of the multimode baseband processing unit are divided into two types of scenes: an energy-saving mode and an operating mode, based on the operating characteristics of the multimode baseband processing unit.

[0024] In some exemplary embodiments, when there is traffic, the multi-mode baseband processing unit switches to an operating mode. For example, the operating conditions include that the current traffic of the base station is above a first preset threshold.

[0025] In some exemplary embodiments, when there is no traffic, the multi-mode baseband processing unit switches to an energy-saving mode. For example, the energy-saving conditions include that the current traffic of the base station is below a second preset threshold.

[0026] In some exemplary embodiments, when the multi-mode baseband processing unit is in the operating mode, the multi-mode baseband processing unit can execute physical layer processing operations and some hardware acceleration processing of the L2 / L3 layer.

[0027] In some exemplary embodiments, when the multi-mode baseband processing unit is in the energy-saving mode, in the multi-mode baseband processing unit, only the Network Transport Layer (NTL) accelerator of the optical port module and the network layer accelerator operates. For the NTL accelerator of the network layer accelerator to operate normally, the cooperation of the clock reset management Call Recording Monitor (CRM) subsystem is required. Therefore, when the multi-mode baseband processing unit is in the energy-saving mode, the clock reset management CRM subsystem also needs to be in an operating state.

[0028] In the embodiments of the present application, whether the multi-mode baseband processing unit is in the operating mode or the energy-saving mode, in any case, normal communication can be carried out between the AAU and the BBU.

[0029] In some exemplary embodiments, a multimode baseband processing unit can be controlled by a main control unit in the multimode baseband processing unit to switch to an energy-saving mode or an operating mode.

[0030] In some exemplary implementations, the situation in which the energy-saving condition is met is when the AAU enters deep sleep mode.

[0031] In some exemplary cases, the operating conditions are met when the AAU's deep sleep ends.

[0032] In some exemplary embodiments, the step of controlling the multimode baseband processing unit in the AAU to enter an energy-saving mode includes the steps of performing a power-off operation on the multimode baseband processing unit in the AAU and loading a first module in the multimode baseband processing unit.

[0033] In some exemplary embodiments, the step of controlling a multimode baseband processing unit to transition to an operating mode includes the step of loading a second module in the multimode baseband processing unit.

[0034] In some exemplary embodiments, the first module includes a clock reset management CRM subsystem, an NTL accelerator among network layer accelerators, and an optical port module.

[0035] In some exemplary embodiments, the second module includes a Digital Signal Processing (DSP) cluster subsystem, a Double Data Rate (DDR) subsystem, a Protocol Conversion Screening (PCS) subsystem, physical layer accelerators, network layer accelerators other than the NTL accelerator, and monolithic system (System on a Chip, SOC) system components.

[0036] In other words, when the multimode baseband processing unit is in energy-saving mode, the modules that need to be loaded include the clock reset management CRM subsystem, the NTL accelerator among the network layer accelerators, and the optical port module.

[0037] When the multimode baseband processing unit is in operating mode, the modules that need to be loaded include the clock reset management CRM subsystem, the NTL accelerator among the network layer accelerators, the optical port module, the DSPcluster subsystem, the DDR subsystem, the PCS subsystem, the physical layer accelerator, and other accelerators among the network layer accelerators other than the NTL accelerator, as well as SOC system components.

[0038] In some exemplary embodiments, the physical layer accelerator includes at least one of the following: an antenna interface system (ANTI) accelerator, a fast fourier transform (FFT) accelerator, a massive MIMO transformation (MMT) accelerator, and a massive MIMO w-value (MMW) calculation accelerator.

[0039] In some exemplary embodiments, the network layer accelerators other than the NTL accelerator include encryption / decryption accelerators.

[0040] In some exemplary embodiments, SOC system components include Direct Memory Access (DMA), Mass Memory Unit (MMU), and the like.

[0041] In the base station control method provided by the embodiment of the present invention, when saving energy in the AAU, the remote radio unit and the multimode baseband processing unit in the AAU are saved simultaneously, and the power consumption of the AAU is significantly reduced while ensuring normal communication between the AAU and the BBU.

[0042] In a second aspect, referring to Figure 2, another embodiment of the present invention provides an electronic device comprising at least one processor 201 and a memory 202 that stores at least one computer program and causes the at least one processor 201 to implement any of the base station control methods when the at least one computer program is executed by the at least one processor 201.

[0043] In some exemplary embodiments, the electronic device further comprises one or more I / O interfaces 203 connected between the processor 201 and the memory 202, which are arranged to enable information interaction between the processor 201 and the memory 202.

[0044] In some embodiments, the processor 201 is a component having data processing capabilities, including but not limited to a central processing unit (CPU). The memory 202 is a device having data storage capabilities, including but not limited to random access memory (RAM, more specifically SDRAM, DDR, etc.), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), and flash memory (FLASH). The I / O interface (read / write interface) 203 is connected between the processor 201 and the memory 202 and enables information interaction between the processor 201 and the memory 202, including but not limited to a data bus.

[0045] In some embodiments, the processor 201, memory 202, and I / O interface 203 are connected to each other via a bus 204 and further connected to other components of the computing device.

[0046] In a third aspect, another embodiment of the present application provides a computer-readable storage medium in which a computer program is stored, wherein when the computer program is executed by a processor, the computer-readable storage medium causes the processor to implement any of the base station control methods.
