[0059] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application.

The flowchart used in this application shows the operations implemented according to some embodiments of the present application. It should be understood that the operations of the flowchart can be implemented out of sequence, and the steps without logical context can be reversed in order or implemented simultaneously. In addition, those skilled in the art can add one or more other operations to the flowchart under the guidance of the content of the present application, or remove one or more operations from the flowchart.

[0060] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0061] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0062] Figure 1 The following is a schematic diagram of the architecture of a wireless communication system provided in an embodiment of the present application. Figure 1 As shown, the wireless communication system may include: base station equipment 5GBBU (Building Baseband Unit, indoor baseband processing unit), network equipment 5GC and maintenance server OMC (Operation and Maintenance Center, operation and maintenance center); the base station equipment and the network equipment transmit signals through a switch, and the base station equipment and the maintenance server also transmit signals through a switch. The base station equipment includes a main processor, a power saving control module and a switching chip; the power saving control module may include: CPLD (Complex Programmable Logic Device, complex programmable logic device) or BMC (Baseboard Management Controller, baseboard management controller).

[0063] Taking the 5GBBU base station equipment using a general-purpose main processor (main CPU) as an example, the BBU motherboard needs to design independent power supplies for the memory and PCIE (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard). The power supply design needs to meet the requirements of CPLD or BMC to power on and off the main CPU separately and the entire board uniformly.

[0064] The base station device can trigger the deep power saving function when it is idle. The OAM (operation and management) module running on the main processor of the base station device triggers the power saving function logic and sends a deep power saving request to the OMC. After receiving the deep power saving request, the OMC determines whether to allow the base station device to enter the deep power saving mode, and when the base station device is allowed to enter the deep power saving mode, it sends a response message to the main processor. The response message carries the GTP (GPRS Tunnelling Protocol) tunnel information from OMC to CPLD / BMC and periodic self-start detection information. After receiving the response message, the main processor sends the GTP tunnel information to the CPLD / BMC, and the CPLD / BMC initiates a tunnel establishment request to the OMC, so that the OMC and the CPLD / BMC establish a GTP tunnel. CPLD / BMC sends a power-saving notification to OAM, and OAM sends a resource suspension request to the network device through the L3 module (RRC (radio resource control), which also includes the processing modules of the signaling plane of the protocol stack such as NGAP). The network device suspends the communication resources between the base station device and the network device, and feeds back the suspension response information to the base station device. After receiving the suspension response information, the base station device stores the protocol stack software and the operating system in the memory, and the main processor notifies CPLD / BMC to complete the power-saving related settings. After that, CPLD / BMC powers off the main processor.

[0065] During the power-off period, the CPLD / BMC can also periodically restore power to the main processor based on the periodic self-start detection information. After power is restored, if the power-saving conditions are met again, the OAM in the main processor will notify the CPLD / BMC to power off the main processor in the above manner.

[0066] Through the above process, the main processor of the base station device is deeply powered off during idle time and periodically powered on during the power-off period.

[0067] Figure 2The present invention provides a flowchart of a power saving processing method for a wireless communication system; the method can be applied to the base station equipment in the above system. Figure 2 As shown, the method may include:

[0068] S101. When detecting that a power-saving condition is met, the main processor sends a power-saving request to a maintenance server.

[0069] An OAM (operation and management) module runs on the main processor. The OAM module in the main processor determines whether a power-saving condition is met, and sends a power-saving request to the OMC when the power-saving condition is met.

[0070] S102: The main processor receives response information sent by the maintenance server, where the response information is used to instruct the maintenance server to allow the main processor to enter a power saving mode.

[0071] The response information includes: data transmission indication information between the maintenance server and the power saving control module.

[0072] After receiving the power saving request, the OMC may determine whether to allow the main processor to enter the power saving mode, and send response information to the main processor when it is determined that the main processor is allowed to enter the power saving mode.

[0073] The response information may include GTP tunnel information from OMC to CPLD / BMC, such as tunnel endpoint identifier (TEID). The GTP tunnel information is used to establish a GTP tunnel between OMC and CPLD / BMC.

[0074] In some embodiments, after receiving the power saving request, the OMC may send a ping message to the CPLD / BMC address. If the ping returns a normal response, the OMC determines to allow the main processor to enter the power saving mode.

[0075] The most basic function of Ping is to test whether the network connection between devices is normal. If Ping can successfully receive a response, it means that the network connection is smooth; otherwise, there may be a network problem.

[0076] In other embodiments, the OMC may determine whether to allow the main processor to enter the power saving mode according to the load of the base station device and the base station devices in the adjacent areas and according to a preset determination strategy.

[0077] For example, the base station coverage takes cellular coverage as an example. Taking the current base station device to be judged whether to save power as the center point, if there are no users in the peripheral adjacent base station devices, it can be determined that the current base station device will not have users switching in for a period of time in the future, so it can be determined that the current base station device is allowed to enter the power saving mode.

[0078] If there is a user under the peripheral adjacent base station device and the user is in a fast moving state (the user's state can be analyzed through the user channel signal), it is determined that the current base station device is not allowed to enter the power saving mode.

[0079] If there is a user under the current base station device, but the user is not transmitting services but is in an idle state, it can be considered that the user has no temporary need to move. In this case, it can also be determined that the current base station device is allowed to enter the power saving mode.

[0080] S103: The main processor sends a response message to the power saving control module, so that the power saving control module establishes a communication tunnel with the maintenance server according to the data transmission indication information.

[0081] After receiving the response information, the OAM running on the main processor may send the response information to the CPLD / BMC, so that the CPLD / BMC initiates a tunnel establishment request to the OMC according to the GTP tunnel information from the OMC to the CPLD / BMC carried in the response information.

[0082] After receiving the tunnel establishment request sent by the CPLD / BMC, the OMC establishes a GTP tunnel to the CPLD / BMC.

[0083] S104: The power saving control module communicates with the maintenance server based on the communication tunnel, and controls the main processor to power off.

[0084] Next, the CPLD / BMC can send a power-saving notification to the OAM, which notifies the L3 module to initiate a resource suspension request to the network device to request that the communication resources between the main processor and the network device be suspended. After the communication resources are successfully suspended, the OAM control completes the power-saving setting and notifies the CPLD / BMC of the completion of the power-saving setting. The CPLD / BMC then powers off the main processor and, based on the communication tunnel with the OMC, notifies the OMC of the power-off completion and enters the deep power-saving mode.

[0085] In summary, the power saving processing method of the wireless communication system provided in this embodiment includes: when the main processor detects that the power saving condition is met, the main processor sends a power saving request to the maintenance server; the main processor receives the response information sent by the maintenance server, and the response information is used to indicate that the maintenance server allows the main processor to enter the power saving mode; the main processor sends a response information to the power saving control module, so that the power saving control module establishes a communication tunnel with the maintenance server according to the data transmission indication information; the power saving control module communicates with the maintenance server based on the communication tunnel, and controls the main processor to power off. When the main processor determines that it meets the power saving condition, this method can trigger a power saving request to the maintenance server, so that when the maintenance server determines that the main processor is allowed to enter the power saving mode, the response information is fed back to the main processor, so that the power saving control module establishes a GTP tunnel with the maintenance server according to the response information, and the power saving control module controls the main processor to power off, and communicates with the maintenance server based on the GTP tunnel to inform that the power saving is completed. Thereby, the idle power-off control of the main processor is completed to reduce the operating power consumption of the base station equipment.

[0086] Figure 3 A flow chart of another power saving processing method for a wireless communication system provided in an embodiment of the present application; Optionally, in step S104, the power saving control module communicates with the maintenance server based on the communication tunnel and controls the main processor to power off, which may include:

[0087] S201. A power saving control module receives a power saving control instruction sent by a maintenance server based on a communication tunnel, and sends a power saving instruction to a main processor.

[0088] After the CPLD / BMC establishes a GTP tunnel with the OMC, the CPLD / BMC can receive a power-saving control instruction sent by the OMC based on the GTP tunnel. The power-saving control instruction is used to instruct the CPLD / BMC to power off the main processor.

[0089] After receiving the power saving control instruction, the CPLD / BMC sends the power saving instruction to the OAM of the main processor. The power saving instruction is used to instruct the OAM to interact with the network device to complete the power saving configuration of the main processor.

[0090] S202: The main processor executes the power saving configuration operation according to the power saving instruction, and feeds back power saving configuration completion information to the power saving control module after completing the power saving configuration.

[0091] Optionally, after receiving the power-saving instruction, the OAM in the main processor controls the execution of the power-saving configuration operation on the main processor, and after completing the power-saving configuration, it feeds back the power-saving configuration completion information to the CPLD / BMC to inform the CPLD / BMC that the relevant configuration before entering the power-saving mode is completed and meets the requirements for entering the power-saving mode.

[0092] S203: The power-saving control module controls the main processor to power off according to the power-saving configuration completion information, and sends a power-off completion message to the maintenance server.

[0093] After receiving the power saving configuration completion information, the CPLD / BMC starts to power off the main processor. After the power off is completed, the CPLD / BMC notifies the OMC that the power off is completed, and the base station equipment enters the deep power saving mode.

[0094] It is worth noting that entering the power saving mode is actively triggered by the main processor and executed by the CPLD / BMC, while exiting the power saving mode is triggered by the CPLD / BMC and the main processor is passively powered on and awakened.

[0095] Optionally, in step S202, the main processor performs a power saving configuration operation according to the power saving instruction, which may include: the main processor performs a resource suspension operation and performs a storage operation of the communication protocol stack program and the operating system in the memory according to the power saving instruction.

[0096] The power saving configuration operation mainly includes two parts, one part is to suspend the communication resources between the main processor and the network device, and the other part is to store the protocol stack software and the operating system in the memory.

[0097] After receiving the power-saving instruction, the OAM of the main processor can first interact with the network device so that the network device can suspend the communication resources between the main processor and the network device; after the resource suspension ends, the OAM controls the storage of the protocol stack software and the operating system in the memory.

[0098] Figure 4 A flowchart of another power saving processing method for a wireless communication system provided in an embodiment of the present application; Optionally, in the above steps, executing a resource suspension operation may include:

[0099] S301. The main processor sends resource suspension request information to a network device, where the resource suspension request information is used to request the network device to suspend resources of a base station device.

[0100] The OAM may notify the L3 module to send resource suspension request information to the network device, so as to request the network device to suspend the communication resources between the network device and the base station device.

[0101] S302: The main processor receives the suspend response information sent by the network device.

[0102] After receiving the resource suspension request information, the network device can suspend the communication resources between the network device and the base station device according to the information indicated by the request. After the suspension is completed, the network device will feedback the suspension response information to the main processor to notify the main processor that the resource suspension is completed.

[0103] Optionally, the resource suspension request information is a target message, the target message includes a target field, and the field value of the target field is used to indicate resource suspension.

[0104] In an implementable manner, the resource suspension request information may be a target message, the target message may include a target field, and the field value of the target field is used to indicate that the resource is to be suspended.

[0105] Exemplarily: the resource suspension request information sent by the main processor to the network device is: RAN CONFIGURATION UPDATE message, the RAN CONFIGURATION UPDATE message contains a cause field, the field value of the cause field is powersaving, powersaving indicates that the base station device needs to save power, then, after the AMF of the network device receives the RAN CONFIGURATION UPDATE message, when it determines that the value of the cause field is powersaving, it can be determined that the communication resources of the base station device need to be suspended, then the AMF suspends the heart beat (heartbeat) and ngap channel (ngap serves as a communication bridge between Ng-RAN (next generation radio access network) and 5GC (5G core network)) from the AMF of the network device to the base station device.

[0106] Afterwards, the AMF may send a suspend response message to the host processor in the manner specified in 3GPP 38.413.

[0107] In another achievable manner, the resource suspension request information sent by the main processor to the network device may include text information indicating resource suspension. The text information may be, for example: the base station device requests to enter power saving mode, or the base station device requests resource suspension, etc.

[0108] Therefore, the network device can perform a resource suspension operation on the base station device according to the text information in the resource suspension request information.

[0109] Figure 5 A flow chart of another power saving processing method for a wireless communication system provided in an embodiment of the present application; Optionally, in the above steps, executing the storage operation of the communication protocol stack program and the operating system in the memory may include:

[0110] S401: The main processor configures the startup mode of the operating system to the fast startup mode.

[0111] After receiving the suspension response information fed back by the network device, the main processor can notify the operating system through the OAM module to change the startup mode to the fast startup mode.

[0112] In the fast boot mode, the main processor skips the process of reading the operating system and protocol stack software from the hard disk. After directly initializing the hardware, it reads the initramfs-xxxx.img file in the memory, completing the system initialization quickly.

[0113] After the system hardware is initialized, the boot loader takes over control and loads the Linux kernel into memory. The kernel then starts executing and searches for the root file system. In this process, the initramfs-xxxx.img file plays a vital role.

[0114] Find the initramfs file: The boot loader will find and load the initramfs-xxxx.img file according to the configuration. This file is usually located in the / boot directory, and the xxxx in the file name usually represents the kernel version number or a specific identifier.

[0115] Loading into memory: Once the initramfs-xxxx.img file is found, the boot loader loads it into memory. This file contains the minimum tools and drivers required to boot a Linux system.

[0116] Unzip and mount: The kernel will unzip the initramfs-xxxx.img file and mount it as a temporary root file system. This temporary file system contains all the necessary files and directories required to boot the system.

[0117] Next, using the initramfs temporary file system, the system can quickly complete the initialization process: Load the root file system: The system reads and executes scripts and programs from initramfs, which are responsible for loading and configuring the real root file system. This usually involves mounting one or more partitions as the root file system.

[0118] Start system services: Once the root file system is loaded, the system will start various necessary system services and daemons.

[0119] S402: The main processor stops running the communication protocol stack program.

[0120] The main processor stops running the communication protocol stack program, and the last working state of the protocol stack program is that the interface of each module remains in an enabled state.

[0121] Optionally, in step S202, feeding back power saving configuration completion information to the power saving control module may include: sending the physical address of the target directory file in the memory to the power saving control module through the operating system; wherein the target directory file is used to indicate the key location for storing core files and configurations required for system startup.

[0122] The operating system sends the physical address of the / boot file in the memory to the CPLD / BMC. The / boot file is an important directory in the Linux operating system. It is usually used to store the system's startup files and kernel. The / boot directory contains various files required by the Linux system when it starts, such as boot programs, kernel image files, etc. These files will be loaded into the memory when the system starts, thereby starting the entire system.

[0123] Figure 6 A flowchart of another power saving processing method for a wireless communication system provided in an embodiment of the present application; Optionally, in step S203, controlling the main processor to power off may include:

[0124] S501: The power saving control module powers off the main processor and the network card.

[0125] CPLD / BMC can power off the main processor and the network card.

[0126] Among them, powering off the network card can ensure that all network communications are terminated correctly, preventing data from being lost or incorrectly sent during the power outage. This helps protect network security and avoid network connection interruptions or data leaks caused by sudden power outages.

[0127] S502: The power saving control module powers off the memory according to the storage location information of the operating system and the communication protocol stack program.

[0128] CPLD / BMC can also power off the memory according to actual preset conditions. The memory here refers to the internal memory.

[0129] It should be noted that in the fast startup mode, the memory does not need to be powered off, while in the non-fast startup mode, both the memory and the hard disk need to be powered off.

[0130] Optionally, the memory includes a first memory module and a second memory module.

[0131] In this embodiment, the memory includes a first memory module and a second memory module as an example, the first memory module may refer to a first memory bar, and the second memory module may refer to a second memory bar. In actual applications, for some more advanced motherboards, more than two memory bars may be installed thereon.

[0132] In step S502, the power saving control module powers off the memory according to the storage location information of the operating system and the communication protocol stack program, which may include: if the operating system and the communication protocol stack program are both stored in the first memory module, then powers off the second memory module.

[0133] Optionally, when the memory needs to be powered off, if the operating system and the communication protocol stack program are both stored in the first memory module, the second memory module can be powered off. Otherwise, neither the first memory module nor the second memory module is powered off.

[0134] Optionally, the response information also includes: periodic power-on information.

[0135] In some embodiments, in step S101, the response information sent by the OMC to the main processor based on the received power saving request may include periodic power-on information in addition to the GTP tunnel information from the OMC to the CPLD / BMC. The periodic power-on information is used to instruct the CPLD / BMC to power on the main processor according to a set time period to detect whether a user has accessed the base station device.

[0136] Exemplarily, the periodic power-on information may be, for example, automatically powering on every 30 minutes to detect whether there is a user access.

[0137] Figure 7 A flowchart of another power saving processing method for a wireless communication system provided in an embodiment of the present application; Figure 7 As shown, the method may also include:

[0138] S601: The power saving control module receives a power-on instruction sent by a maintenance server, and triggers the main processor to resume powering on according to periodic power-on information.

[0139] In some embodiments, after receiving the power-on instruction sent by the OMC, the CPLD / BMC may trigger the main processor to resume powering on according to the power-on time indicated by the periodic power-on information.

[0140] In other embodiments, the CPLD / BMC may also actively trigger the main processor to resume powering on based on periodic power-on information, without waiting for the OMC to issue a power-on instruction.

[0141] S602: The power saving control module receives the indication information sent by the main processor, and based on the indication information, sends a main processor power-on completion message to the maintenance server.

[0142] The indication information is used to instruct the power-saving control module to send a power-on completion message to the maintenance server; the power-on completion message includes: a network protocol address of the main processor.

[0143] After the main processor is powered on, it can send indication information to the CPLD / BMC through OAM, and the indication information is used to instruct the CPLD / BMC to notify the OMC of the power-on completion.

[0144] Based on the indication information, the CPLD / BMC may send a power-on completion message to the OMC to notify the OMC that the main processor has completed powering on.

[0145] S603: The main processor receives a power-on completion confirmation message fed back by the maintenance server, and restores the connection with the network device.

[0146] Based on the received power-on completion message, the OMC will send a power-on completion confirmation message to the main processor and restore the connection between the main processor and the network device. After that, the base station device can communicate normally with the network device.

[0147] Figure 8 A flowchart of another power saving processing method for a wireless communication system provided in an embodiment of the present application; optionally, in step S601, triggering the main processor to resume power-on according to periodic power-on information may include:

[0148] S701. The power saving control module determines whether the current power-on condition is met according to the periodic power-on information. If so, the physical address of the target directory file in the memory is sent to the main processor through the interface address of the power saving control module.

[0149] Optionally, the CPLD / BMC can determine whether the current time reaches the power-on time based on the periodic power-on time indicated in the periodic power-on information. If so, the CPLD / BMC first triggers the main processor to power on, and then sends the physical address in the memory where the / boot file is located to the main processor through the interface address.

[0150] S702: The main processor reads the physical address, enters the fast startup mode, and starts the communication protocol stack program.

[0151] After the main processor reads the physical address information, it enters the fast startup mode and starts the communication protocol stack program. After the communication protocol stack program is started, it does not send a heartbeat message to the network device until it detects that the user has accessed the base station device and then sends a heartbeat message to the network device.

[0152] Optionally, after the CPLD / BMC restores the power of the main processor, the OAM in the main processor can continue to detect whether there are any users accessing the base station device. For example, if there is no user access for 30 consecutive minutes and no target user is attached to the cell covered by the base station device, the OAM can initiate a power-saving request to the OMC again and power off the main processor again according to the above-mentioned power-saving processing flow.

[0153] Fig. 9A flowchart of another power saving processing method for a wireless communication system provided in an embodiment of the present application; Optionally, in step S603, restoring the connection with the network device may include:

[0154] S801: The main processor notifies the power saving control module to disconnect from the maintenance server.

[0155] In some embodiments, after the main processor receives the power-on completion confirmation message sent by the OMC, the OAM of the main processor notifies the CPLD / BMC to disconnect the GTP tunnel connection with the OMC. At the same time, based on the received main processor power-on completion message, the OMC will also disconnect from the CPLD / BMC.

[0156] S802: The main processor restores the connection between the application protocol and the network device, and sends a heartbeat message to the network device.

[0157] The main processor starts up according to the default startup mode, the NGAP restores the connection with the network device, sends a heartbeat message, and sends a request for updating the configuration of the wireless access network node to update the node status of the wireless access network.

[0158] Afterwards, the base station equipment handles user access and service transmission normally.

[0159] In summary, the power saving processing method of the wireless communication system provided in this embodiment includes: when the main processor detects that the power saving condition is met, the main processor sends a power saving request to the maintenance server; the main processor receives the response information sent by the maintenance server, and the response information is used to indicate that the maintenance server allows the main processor to enter the power saving mode; the main processor sends a response information to the power saving control module, so that the power saving control module establishes a communication tunnel with the maintenance server according to the data transmission indication information; the power saving control module communicates with the maintenance server based on the communication tunnel, and controls the main processor to power off. When the main processor determines that it meets the power saving condition, this method can trigger a power saving request to the maintenance server, so that when the maintenance server determines that the main processor is allowed to enter the power saving mode, the response information is fed back to the main processor, so that the power saving control module establishes a GTP tunnel with the maintenance server according to the response information, and the power saving control module controls the main processor to power off, and communicates with the maintenance server based on the GTP tunnel to inform that the power saving is completed. Thereby, the idle power-off control of the main processor is completed to reduce the operating power consumption of the base station equipment.

[0160] In addition, after the main processor is powered off, the power saving control module can also automatically trigger the periodic power-on restoration of the main processor according to the periodic power-on information in the response information fed back by the maintenance server, and enter the deep power saving mode again when the power saving conditions are met.
