Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a base station energy saving method, a base station and related equipment, and a storage medium. Background Art

[0002] In the communication system, the base station is the key device for mobile devices to access the network. It can ensure that the mobile terminal can maintain a signal anytime and anywhere during the movement, and can ensure the needs of making calls and sending and receiving information. Due to the special nature of the base station, the base station needs to be turned on at all times so that the mobile terminal can access the network, which also causes the energy consumption of the base station to be very high.

[0003] Currently, base stations decide whether to shut down or enter sleep mode based on their load to save energy. This can cause gaps in the base station's network coverage, preventing some users from accessing the network and affecting the user experience.

[0004] Therefore, it is of great significance to reduce the energy consumption of base stations and ensure that users can access the network. Summary of the invention

[0005] The present application at least provides a base station energy saving method, a base station and related equipment, and a storage medium.

[0006] The first aspect of the present application provides a method for energy saving of a base station, the method comprising: detecting the user access status of the base station; if the user access status meets the preset access user conditions, determining to enter the energy saving mode; when the base station is in the energy saving mode, sending part of the information in the wireless frame to be sent or not sending the information in the wireless frame to be sent.

[0007] Therefore, after the base station detects that the user access situation meets the preset user access conditions, it adjusts the base station mode so that the base station only sends part of the information in the wireless frame to be sent or does not send the information in the wireless frame to be sent, thereby reducing the number of messages that the base station needs to send, thereby reducing the base station's transmission power and energy consumption. There is no need to shut down the base station, which does not affect the user's normal access to the network.

[0008] The second aspect of the present application provides a base station, which includes: a detection module, an acquisition module and an adjustment module, the detection module is used to detect the user access status of the base station; when the detection circuit detects that there is no access user, the acquisition module is used to obtain the sending information contained in the wireless frame to be sent; when the base station is in energy-saving mode, the transmission module is used to send part of the information in the wireless frame to be sent or not send the information in the wireless frame to be sent.

[0009] A third aspect of the present application provides an electronic device, which includes a memory and a processor coupled to each other, and the processor is used to execute program instructions stored in the memory to implement the base station energy saving method in the first aspect above.

[0010] A fourth aspect of the present application provides a computer-readable storage medium having program instructions stored thereon, and when the program instructions are executed by a processor, the base station energy saving method in the above-mentioned first aspect is implemented.

[0011] In the above scheme, when the user access situation meets the preset user access conditions, the base station adjusts the base station mode so that the base station can only send part of the information in the wireless frame to be sent or not send the information in the wireless frame to be sent, thereby reducing the number of messages that the base station needs to send, thereby reducing the energy consumption of the base station, and there is no need to shut down the base station, which does not affect the user's normal access to the network.

[0019] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0020] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0021] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. In addition, "many" in this article means two or more than two. In addition, the term "at least one" in this article means any combination of at least two of any one or more of a plurality of, for example, including at least one of A, B, and C, can mean including any one or more elements selected from the set consisting of A, B, and C.

[0022] See also Figure 1 , Figure 1 This is a schematic diagram of the first process of an embodiment of the base station energy saving method of the present application. Specifically, it may include the following steps:

[0023] Step S11: Detect whether the user access situation of the base station meets the preset access user situation.

[0024] The executor of the base station energy-saving method described in this application can be a base station in a communication system, such as a 4G base station, a 5G base station, or a base station used for private network communication.

[0025] The mobile terminal can establish a communication connection with the base station, and the base station can determine its own working status according to the access status of the user (mobile terminal). Therefore, in the present application, the base station can detect the access status of its own users to determine whether there are users accessing the base station, the number of users accessing the base station, and so on. In the present application, by detecting the user access status, it can be determined whether the current user access status meets the preset conditions, and the subsequent working mode of the base station can be determined accordingly. In this embodiment, it can be determined whether the user access status meets the preset access user conditions. If it does, steps S12 and S13 can be executed; if it does not, steps S14 and S15 can be executed. Step S12: Determine to enter the energy saving mode.

[0026] When the base station detects that the user access situation meets the preset access user conditions, the base station will determine to enter the energy saving mode. The preset access user conditions are, for example, that the base station is in a situation where there is no access user. At this time, because the base station has no access users, the base station can selectively not send some information that does not affect user access, thereby reducing the energy consumption of the base station.

[0027] In a specific implementation scenario, the user access situation mentioned above is specifically that the base station has no access users and the duration is greater than a preset threshold. When the base station is in a no-access user situation, in order to improve the stability of the system, the base station may determine to enter the energy-saving mode only when there is no access user in the base station and the duration is greater than a preset threshold. The preset threshold is, for example, 10 seconds, 15 seconds, etc., and the setting of the preset threshold can be adjusted as needed.

[0028] After entering the energy-saving mode, step S13 may be continued.

[0029] Step S13: When the base station is in the energy-saving mode, part of the information in the wireless frame to be sent is sent or no information in the wireless frame to be sent is sent.

[0030] The base station is in energy-saving mode. When sending a wireless frame to be sent, the base station may send part of the information in the wireless frame to be sent or may not send the information in the wireless frame to be sent. The base station may send part of the information in the wireless frame to be sent, which may specifically be information of some subframes in the wireless frame to be sent. For example, the base station may not send information irrelevant to the user accessing the base station, but may only send information related to the user accessing the base station.

[0031] Therefore, after the base station detects that the user access situation meets the preset user access conditions, it adjusts the base station mode so that the base station only sends part of the information in the wireless frame to be sent or does not send the information in the wireless frame to be sent, thereby reducing the number of messages that the base station needs to send, thereby reducing the base station's transmission power and energy consumption. There is no need to shut down the base station, which does not affect the user's normal access to the network.

[0032] In one embodiment, the transmission power of the base station can be reduced by adjusting the radio frequency transmission circuit in the base station. For example, the transmission power of the base station can be reduced by adjusting the working state of the power amplifier in the base station. Specifically, after the base station enters the energy-saving mode, the power amplifier can be adjusted to the first working state, and the state of the power amplifier can be adjusted by controlling the radio frequency signal input to the power amplifier.

[0033] When the base station enters the energy-saving mode and the power amplifier is in the first working state, if the base station only sends part of the information in the wireless frame to be sent, the RF signal input to the power amplifier can be controlled to be only the RF signal carrying this part of the information, so the power amplifier only needs to amplify this part of the RF signal, thereby reducing the RF signal that the power amplifier needs to amplify and process, thereby reducing the transmission power of the base station. If the base station does not send the information in the wireless frame to be sent, no RF signal is input to the power amplifier, so the power amplifier does not need to work, that is, the transmission power of the base station is 0 at this time. When it is determined to send only part of the information in the wireless frame to be sent or not to send the information in the wireless frame to be sent, by reducing the RF signal that needs to be input to the power amplifier, the RF signal that the power amplifier needs to amplify and process is reduced, thereby reducing the transmission power of the base station.

[0034] After step S11, if it is detected that the user access situation does not meet the preset access user conditions, step S14 may be executed.

[0035] Step S14: Determine to enter the normal mode.

[0036] When the base station detects that the user access situation does not meet the preset user access conditions, it can be determined that the base station enters the normal mode.

[0037] Step S15: When the base station is in normal mode, all information in each wireless frame to be sent is sent.

[0038] When the base station is in normal mode, the base station can send all information in each wireless frame to be sent. The information sent by the base station includes, for example, information related to user access and information not related to user access. Information not related to user access is, for example, various information sent when communicating with the user.

[0039] In one embodiment, when it is determined that the base station is in normal mode, all information in each to-be-sent wireless frame can be sent by adjusting the RF transmission circuit of the base station. For example, the power amplifier of the base station can be adjusted to the second working state. When the power amplifier is in the second working state, the base station sends all the transmission information in each to-be-sent wireless frame, that is, the RF signal used to carry the entire to-be-sent wireless frame is input into the power amplifier, and the RF signal is amplified and transmitted by the power amplifier, so that users who have accessed the base station can communicate normally.

[0040] See also Figure 2 , Figure 2This is a second flow diagram of an embodiment of the base station energy saving method of the present application. This embodiment further expands the "sending part of the information in the wireless frame to be sent or not sending the information in the wireless frame to be sent" mentioned in the above step S13, and specifically includes the following steps S131 to S133.

[0041] Step S131: Determine whether the information in the wireless frame to be sent includes a first preset sending message.

[0042] After the base station enters the energy-saving mode, it can determine which messages in the wireless frame to be sent are specifically needed according to the type of the wireless frame to be sent. Therefore, the base station can determine which messages need to be sent by judging whether the information in the wireless frame to be sent includes the first preset sending message. In a specific implementation, judging whether the information in the wireless frame to be sent includes the first preset sending message can specifically be judging whether the subframe carrying the wireless frame to be sent includes the first preset sending message.

[0043] In one embodiment, the first preset message to be sent is a broadcast message. Because the broadcast message involves the process of the user accessing the base station, it is possible to further determine which part of the information in the to-be-sent wireless frame needs to be sent by judging whether the to-be-sent wireless frame includes the broadcast message. Specifically, the broadcast message includes at least one of: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), information transmitted using a physical broadcast channel (PBCH), a system information block 1 (SIB1) and a system information block 2 (SIB2).

[0044] If the information in the wireless frame to be sent includes the first preset sending message, step S132 is executed; if the information in the wireless frame to be sent does not include the first preset sending message, step S133 is executed.

[0045] Step S132: Send a second preset sending message in the wireless frame to be sent, where the second preset sending message at least includes a portion of the first preset sending message.

[0046] The information in the wireless frame to be sent includes a first preset sending message, which means that the message sent by the wireless frame to be sent involves the process of the user accessing the base station. Therefore, the base station can send a second preset sending message in the wireless frame to be sent, wherein the second preset sending message includes at least part of the first preset sending message.

[0047] In one embodiment, the second preset sending message includes at least one of a broadcast message, a cell reference signal (CRS), and a message transmitted using a physical control information indicator channel (PCFICH). Specifically, the base station sends the second preset sending message in the wireless frame to be sent, and specifically, it can be sending a subframe containing the second preset sending message in the wireless frame to be sent.

[0048] For example, the base station may send part of the first preset sending message, and also send a cell reference signal and a message transmitted using a physical control information indication channel. In a specific scenario, the wireless frame to be sent includes a message transmitted using a physical downlink control channel (PDCCH), a cell reference signal, a message transmitted using a physical control information indication channel, a primary synchronization signal, and a secondary synchronization signal. Among these information, the primary synchronization signal and the secondary synchronization signal belonging to the first preset sending message are included. Therefore, the base station will send the primary synchronization signal, the secondary synchronization signal, the cell reference signal, and the message transmitted using the physical control information indication channel, but will not send the message transmitted using the physical downlink control channel.

[0049] The base station sends the second preset sending message, so that the terminal can receive the second preset sending message and establish a communication connection with the base station. The base station only sends the second preset sending message, and other messages are not sent, thereby reducing the base station's transmission power and reducing the base station's energy consumption.

[0050] Step S133: Do not send the information in the wireless frame to be sent.

[0051] When the information in the wireless frame to be sent does not include the first preset sending message, it means that the information contained in the wireless frame to be sent does not involve the process of the user accessing the base station, so the base station can choose not to send the wireless frame to be sent, thereby reducing the transmission power consumption of the base station to achieve the purpose of energy saving.

[0052] In a specific implementation scenario, the wireless frame to be sent includes a message transmitted using a physical downlink control channel, a cell reference signal, and a message transmitted using a physical control information indication channel. It can be seen that the wireless frame to be sent does not include the first preset sending message, so the base station will not send the wireless frame to be sent.

[0053] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.

[0054] In a specific implementation, the first working state of the power amplifier includes a low-power working state and a static working state, and the difference between the two is whether a radio frequency signal is input into the power amplifier. In the case where the information in the wireless frame to be sent includes the first preset sending message, the base station will send the second preset sending message, and the working state of the power amplifier can be adjusted to a low-power working state. Adjusting the working state of the power amplifier is to input the radio frequency signal used to carry the second preset sending message into the power amplifier, and use the power amplifier to process this part of the radio frequency signal. In the case where the information in the wireless frame to be sent does not include the first preset sending message, the base station will not send the information in the wireless frame to be sent, and the working state of the power amplifier can be adjusted to a static working state, and the radio frequency signal will not be input into the power amplifier. Therefore, when only part of the information (the second preset sending message) in the wireless frame to be sent is sent or the information in the wireless frame to be sent is not sent, the power of the power amplifier is reduced by reducing the radio frequency signal input to the power amplifier, or not inputting the radio frequency signal into the power amplifier, so that the transmission power of the base station can be reduced.

[0061] The above-mentioned preset access user condition includes that the user access situation is that there is no access user, or the user access situation is that there is no access user and the duration is greater than a preset threshold.
