Abstract
Description
Technical Field
[0001] The present application relates to the field of wireless network communication technology, and in particular to a power control method, system, device and medium. Background Art
[0002] With the rapid development of wireless communication technology, terminal devices such as mobile phones, tablets, and 4G cameras can now connect to the Internet using wireless network communications (WiFi), primarily based on the WiFi protocol. However, WiFi protocols lack power control, unlike the strict closed-loop power control implemented in 3G, 4G, and 5G protocols. Currently, WiFi power regulation relies on binding transmit power to data rate. Low-rate modes utilize higher transmit power, such as 11b, 6Mbps, and MCS0, typically using 16-18dBm, while high-rate modes utilize lower power, such as 13-15dBm for 54Mbps and MCS7. This power control is primarily achieved through rate selection. For a fixed rate, power remains constant across all operating environments.

[0049] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0050] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.
[0051] In existing WiFi technologies, transmit power is primarily tied to data rate, enabling power control through rate selection. The set power value varies with the data rate, with minimal differences between levels. This is typically achieved by configuring a WiFi power control table. Once a WiFi power control table is established, it cannot be changed at will. Given a fixed data rate, power remains constant across all operating environments. In other words, existing WiFi technologies typically only have one power table configured, and power adjustment is based on data rate. If the initial power setting is too high, overpower may occur in most scenarios. If the initial power setting is too low, coverage may be limited.
[0052] In order to solve the above problems, the embodiments of the present application propose a power control method, system, device and medium, which pre-sets at least two power configuration tables and determines the target communication signal based on the wireless network communication connection between the mobile terminal and the wireless access point. Then, based on the working environment of the target communication signal, the power table adjustment information is determined in combination with the signal strength indication information of the target communication signal, so as to switch the power configuration table according to the power table adjustment information, so as to achieve the purpose of switching to the corresponding power configuration table according to different working environments. The power configuration table after switching is the target power configuration table, so that power adjustment can be performed according to the power configuration information in the target power configuration table to obtain the target transmission power corresponding to the wireless network communication connection, so as to reduce the transmission power while ensuring communication, thereby effectively reducing energy consumption and extending standby time.
[0053] Reference Figure 1 , shows a schematic flow chart of the steps of a power control method provided by an embodiment of the present application. Figure 1 As shown, the power control method provided in the embodiment of the present application may specifically include the following steps:
[0054] Step 110, determining a target communication signal based on the wireless network communication connection between the mobile terminal and the wireless access point;
[0055] In the embodiments of the present application, a mobile terminal refers to a mobile terminal that can establish a network communication connection with a wireless access point (AP) in a wireless mode, such as a mobile phone, tablet computer, smart bracelet, or other user terminal with a specific WiFi connection function, and this embodiment does not limit this. After the mobile terminal and the AP establish a wireless network communication connection, the network communication signal corresponding to the wireless network communication connection can be determined as the target communication signal. For example, after a mobile phone establishes a WiFi connection with an AP, the WiFi signal to which the mobile phone is connected can be determined as the target communication signal.
[0056] Step 120: determining power meter adjustment information based on the operating environment of the target communication signal and the signal strength indication information of the target communication signal;
[0057] Among them, the power meter adjustment information is used to indicate the switching of the power configuration table, such as the power adjustment information may be power meter upgrade information or power meter downgrade information, etc., and this embodiment does not impose specific restrictions on this; the power meter downgrade information may refer to the downgrade information of the power meter, such as the power downgrade information may be used to indicate that the power configuration table used corresponding to the wireless network communication connection is downgraded to the power configuration table of the next level; the power meter upgrade information may refer to the upgrade level information of the power meter, such as the power upgrade information may be used to indicate that the power configuration table used corresponding to the wireless network communication connection is upgraded to the power configuration table of the previous level; the working environment of the target communication signal refers to the current usage environment of the target communication signal.
[0058] Specifically, in order to use the lowest transmission power while ensuring the quality of communication, after determining the target communication signal, the embodiment of the present application can determine the use environment of the target communication signal to determine the current use environment of the target communication signal as the working environment, and can obtain the signal strength indication information of the target communication signal to determine the received signal strength, so as to determine whether it is necessary to switch the power configuration table corresponding to the wireless network communication connection according to the signal strength and the working environment, and generate power table adjustment information. The power table adjustment information can be specifically used to switch the power configuration table corresponding to the wireless network communication connection, so as to switch the corresponding power configuration table according to different use environments, so as to achieve the purpose of using the lowest transmission power while ensuring communication. It should be noted that the signal strength indication information of the target communication signal can be used to determine the signal strength of the target communication signal, such as the signal strength indication information can be the received signal strength indication (RSSI), which is not limited in this embodiment.
[0059] Step 130: Switch the power configuration table according to the power table adjustment information. The power configuration table after switching is the target power configuration table.
[0060] In this step, the power configuration table can be switched based on the power table adjustment information, and the power configuration tables before and after the switching are both included in at least two pre-configured power configuration tables. After the power configuration table is switched, the power configuration table used after the switching can be determined as the target power configuration table, so that power adjustment can be performed based on the power configuration information in the target power configuration table, that is, step 140 is executed.
[0061] In one embodiment of the present application, at least two power configuration tables may be pre-set, each of which is a table indicating transmit power. Specifically, in order to switch to a corresponding power configuration table according to different usage environments, multiple power configuration tables may be pre-configured to serve as power tables corresponding to wireless network communication connections. For example, before determining a target communication signal based on the wireless network communication connection between a mobile terminal and a wireless access point, at least two or more power configuration tables may be pre-configured for the wireless network communication connection, so that the corresponding power configuration table can be subsequently switched according to different usage environments.
[0062] Step 140: Adjust the transmit power corresponding to the wireless network communication connection according to the power configuration information in the target power configuration table.
[0063] Specifically, after the power configuration table is switched, this embodiment can adjust the transmission power corresponding to the wireless network communication connection based on the power configuration information in the target power configuration table to adjust the transmission power to the power corresponding to the current communication rate, so that the lowest transmission power can be used for signal transmission while ensuring communication, and the current during transmission can be reduced while ensuring communication quality, saving energy.
[0064] In summary, this embodiment determines a target communication signal based on a wireless network communication connection between a mobile terminal and a wireless access point, and determines power table adjustment information based on the operating environment of the target communication signal and in combination with signal strength indication information of the target communication signal, so as to switch the power configuration table according to the power table adjustment information, thereby achieving the purpose of switching to a corresponding power configuration table according to different operating environments. The power configuration tables before and after the switching are both included in at least two pre-configured power configuration tables, and the power configuration table after the switching is the target power configuration table. Subsequently, based on the power configuration information in the target power configuration table, the transmit power corresponding to the wireless network communication connection is adjusted to reduce the transmit power while ensuring communication. This can reduce the current during transmission while ensuring communication quality, saving energy consumption. This solves the problem of excess power or small coverage caused by using only one power configuration table to adjust the transmit power in existing WiFi technology, and can effectively extend the standby time.
[0065] The following is an illustrative description of the embodiments of the present application, but it should be noted that the implementation of the present application may have the features described below, but the following description does not constitute a limitation on the scope of protection of the embodiments of the present application.
[0066] In some optional embodiments of the present application, before determining the target communication signal, the power control method provided by the embodiment of the present application may further include: pre-setting at least two power configuration tables, so that the power configuration table can be switched based on the at least two pre-set power configuration tables. Specifically, in the embodiment of the present application, when at least two power configuration tables are pre-set, the current working environment of the target communication signal can be determined by obtaining signal interference information and bit error rate information corresponding to the target communication signal, so as to switch to the corresponding power configuration table according to the current working environment, thereby achieving the purpose of switching the corresponding power configuration table according to different working environments, thereby ensuring the use of the lowest transmission power while ensuring communication, solving the problem caused by using a fixed power configuration table for WiFi power control in the prior art.
[0067] Optionally, an embodiment of the present application determines power meter adjustment information based on the working environment of the target communication signal in combination with the signal strength indication information of the target communication signal, including: obtaining signal interference information and bit error rate information corresponding to the target communication signal; using the signal interference information in combination with the bit error rate information corresponding to the target communication signal to determine the working environment; judging the working environment, if the working environment belongs to a preset interference environment, then when the continuous interference duration corresponding to the working environment reaches a preset interference duration threshold, the power meter upgrade information corresponding to the interference environment is determined as the power meter adjustment information; if the working environment belongs to a preset clean environment, then based on the signal strength indication information, the power meter downgrade information corresponding to the clean environment is determined as the power meter adjustment information.
[0068] Reference Figure 2 , is a schematic flow chart of the steps of a power control method provided in an optional embodiment of the present application. Figure 2 As shown, the power control method provided in the embodiment of the present application may include the following steps:
[0069] Step 210: pre-set at least two power configuration tables;
[0070] Step 220, determining a target communication signal based on the wireless network communication connection between the mobile terminal and the wireless access point;
[0071] Step 230: Acquire signal interference information and bit error rate information corresponding to the target communication signal;
[0072] The signal interference information can be used to determine the signal interference situation of the current working environment, such as including channel interference information. Optionally, in this embodiment, obtaining the signal interference information corresponding to the target communication signal may include the following sub-steps:
[0073] Sub-step 2301, determining the communication channel of the target communication signal;
[0074] Sub-step 2302: detecting channel interference information corresponding to the communication channel;
[0075] Sub-step 2303: determining the channel interference information as the signal interference information.
[0076] In an embodiment of the present application, channel interference information can be used to determine the channel interference situation. For example, channel interference information can be used to determine the interference strength of the communication channel currently used by the target communication signal. Specifically, it may include: signal strength parameters of other APs in the surrounding environment, signal strength parameters emitted by other electronic devices on the same working channel, etc. This embodiment does not limit this.
[0077] It should be noted that the signal strength parameters of other APs around the environment can be used to determine the signal strength of other APs around the environment; the signal strength parameters transmitted by other electronic devices on the same working channel can be used to determine the signal strength transmitted by other electronic devices on the same working channel. For example, when the target communication signal is transmitted using the public 2.4G frequency band, the signal strength transmitted by other electronic devices on the 2.4G frequency can be determined as the channel interference information corresponding to the communication channel.
[0078] The bit error rate information corresponding to the target communication signal may be used to determine the bit error rate corresponding to the target communication signal. For example, the bit error rate may be the bit error rate of the AP end and the mobile terminal.
[0079] Step 240, using the signal interference information in combination with bit error rate information corresponding to the target communication signal to determine a working environment;
[0080] Specifically, after determining the signal interference information, this embodiment can determine the current usage environment based on the signal interference information and the bit error rate information corresponding to the target communication signal, that is, the signal interference information corresponding to the target communication signal is used in combination with the bit error rate information to determine the working environment, and the working environment can be judged, so that when interference occurs in the current usage environment, it can be judged that the working environment belongs to the preset interference environment. For example, when the current usage environment is particularly harsh, has not improved for a long time, and there is no clean channel that can be switched, it can be determined that the current working environment of the target communication signal belongs to the preset interference environment, and then jump to step 250 for execution; and when the current usage environment is good, such as in a usage environment with good signal and low interference, it can be judged that the current working environment of the target communication signal belongs to the preset clean environment, and then jump to step 260 for execution.
[0081] Step 250: If the working environment belongs to a preset interference environment, then when the continuous interference duration corresponding to the working environment reaches a preset interference duration threshold, the power meter upgrade information corresponding to the interference environment is determined as power meter adjustment information;
[0082] Specifically, after determining that the current working environment of the target communication signal belongs to the preset interference environment, this embodiment can determine whether there is long-term interference in the working environment by judging whether the continuous interference duration corresponding to the working environment reaches the preset interference duration threshold. In this way, when the working environment is in the case of long-term interference, the power meter upgrade information can be determined as the power meter adjustment information, that is, when the continuous interference duration corresponding to the working environment reaches the preset interference duration threshold, the power meter upgrade information is determined as the power meter adjustment information, so that the power table adjustment information can be used to switch the power configuration table subsequently, so that the power configuration table corresponding to the interference environment can be switched to perform power adjustment to ensure communication quality.
[0083] In an optional embodiment, in order to ensure normal wireless network communication connection, when the working environment changes from a clean environment to an interference environment and the transmission power needs to be increased, minute-level monitoring can be implemented, such as monitoring at intervals of 15 minutes, so that when the continuous interference duration reaches a preset interference duration threshold, such as when the preset interference duration threshold is 15 minutes, when it is detected that the continuous interference duration reaches 15 minutes, it can be considered that strong interference is continuously output, and the power increase mechanism is started. Based on the power increase mechanism, the power meter is upgraded in a step-by-step switching mode without skipping switching to ensure continuous communication.
[0084] For example, Figure 3 As shown, in the case where the pre-set multiple power configuration tables include six power configuration tables, namely power table-1, power table 0, power table 1, power table 2, power table 3, and power table 4, the fourth-level power table 4 can be upgraded to the third-level power table 3, or from the third-level power table 3 to the second-level power table 2, and so on, until the power table upgrade stops when it is upgraded to the highest-level power table-1. Among them, the level of power table-1 is the highest, which is the preset second default level; the level of power table 0 is the default usage level, that is, power table 0 is set as the initial power table, and the default usage level is lower than the preset second default level and higher than the first level; the level of power table 1 is the first level, the level of the second power table 2 is the second level, ... and so on, the level of power table N is the Nth level, which is lower than the N-1th level, and N is an integer greater than 1. The level of power table N is the lowest, which is the preset first default level.
[0085] Furthermore, in the present application, when the duration of continuous interference corresponding to the working environment reaches a preset interference duration threshold, determining the power table upgrade information corresponding to the interference environment as the power table adjustment information may specifically include: when the duration of continuous interference corresponding to the working environment reaches the preset interference duration threshold, determining the current transmit power configuration table based on the transmit power of the target communication signal, wherein the current transmit power configuration table is the power configuration table before switching; determining the level of the current transmit power configuration table; if the level of the current transmit power configuration table is not a preset second default level, determining the power table upgrade information corresponding to the interference environment as the power table adjustment information. If the level of the current transmit power configuration table is the preset second default level, the power table upgrade information may not be determined as the power table adjustment information, thereby stopping the power table upgrade. The preset second default level may be the highest level of at least two pre-set power configuration tables; the preset interference duration threshold may be determined based on transmit power adjustment requirements, such as half an hour, one hour, four hours, etc., which is not limited in this embodiment.
[0086] Step 260: If the working environment is a preset clean environment, then based on the signal strength indication information of the target communication signal, determine the power meter degradation information corresponding to the clean environment as the power meter adjustment information;
[0087] Specifically, after determining that the current working environment of the target communication signal belongs to a preset clean environment, this embodiment can determine the signal strength of the target communication signal through the signal strength indication information of the target communication signal, so that when the signal strength of the target communication signal is greater than a certain signal strength threshold, the power meter degradation information corresponding to the clean environment is determined as the power meter adjustment information, so that the power table adjustment information can be used to switch the power configuration table subsequently, thereby switching to the power configuration table corresponding to the clean environment for power adjustment, and then using the lowest transmission power for transmission while ensuring communication, thereby reducing energy consumption.
[0088] In an optional embodiment of the present application, based on the signal strength indication information, the power meter degradation information corresponding to the clean environment is determined as the power meter adjustment information, which may specifically include: using the signal strength indication information to determine the signal strength of the target communication signal; when the signal strength exceeds a preset signal strength threshold, the power meter degradation information corresponding to the clean environment is determined as the power meter adjustment information.
[0089] For example, to ensure normal connection, when the operating environment is good and the power needs to be adjusted downward, hourly environmental monitoring can be implemented. For example, if the environment is detected to be very clean for 4 consecutive hours, that is, when the working environment belongs to the preset clean environment, the power reduction mechanism is enabled, and the power meter is downgraded to the next level of power configuration table using a step-by-step switching mode, without skipping switching, to ensure continuous communication. For example, in an environment with good signal and low interference, it can be determined that the current working environment belongs to the preset clean environment. First, the default power table 0 can be downgraded to power table 1. After a period of continuous operation, environmental monitoring can be performed again (specific settings can be made based on the debugging situation). When the working environment is detected to be the preset clean environment, the power meter can be downgraded again. In this way, by continuously detecting the current environment multiple times, if the working environment is still very good, the transmission power configuration table can be downgraded to power table 2. Similarly, in an excellent environment, it can be downgraded to power table 4. Among them, the period of continuous operation can be set according to the debugging situation, and this embodiment does not limit this.
[0090] In an optional embodiment, when the signal strength exceeds a preset signal strength threshold, this embodiment determines the power meter downgrade information corresponding to the clean environment as the power meter adjustment information. This may specifically include: when the signal strength exceeds the preset signal strength threshold, determining a current transmit power configuration table based on the transmit power of the target communication signal; determining a level of the current transmit power configuration table, wherein the current transmit power configuration table is the power configuration table before switching; if the level of the current transmit power configuration table is not a preset first default level, determining the power meter downgrade information corresponding to the clean environment as the power meter adjustment information. If the level of the current transmit power configuration table is the preset first default level, the power meter downgrade information may not be determined as the power meter adjustment information, thereby stopping the power meter downgrade. The preset first default level may be the lowest level of at least two pre-set power configuration tables; the signal strength threshold may be determined based on the transmit power adjustment requirements, which is not limited in this embodiment.
[0091] Step 270: Switch the power configuration table according to the power table adjustment information, the power configuration table after the switch is the target power configuration table, and the power configuration tables before and after the switch are both included in the at least two pre-configured power configuration tables;
[0092] In this embodiment, in order to ensure communication continuity, after determining the power table adjustment information, a step-by-step switching mode can be used to switch the power configuration table based on the power table adjustment information, so as to determine the target power configuration table with the power configuration table used after the switching. Optionally, this embodiment switches the power configuration table based on the power table adjustment information, which can specifically include: using the wireless transmission power of the target communication signal to determine the current transmission power configuration table, wherein the current transmission power configuration table is the power configuration table before the switching; if the power table adjustment information is power table upgrade information, the previous level power configuration table corresponding to the current transmission power configuration table is determined as the target power configuration table; if the power table adjustment information is power table downgrade information, the next level power configuration table corresponding to the current transmission power configuration table is determined as the target power configuration table.
[0093] Step 280: Adjust the transmit power corresponding to the wireless network communication connection according to the power configuration information in the target power configuration table.
[0094] As can be seen, after determining the target communication signal based on the wireless network communication connection between the mobile terminal and the wireless access point, this embodiment determines the operating environment of the target communication signal by using the signal interference information corresponding to the target communication signal, and using the obtained signal interference information in combination with the bit error rate information corresponding to the target communication signal. Based on the operating environment of the target communication signal, the power table adjustment information can be determined in combination with the signal strength indication information of the target communication signal, and the power configuration table can be switched according to the power table adjustment information, thereby achieving the purpose of switching to the corresponding power configuration table according to different operating environments. Compared with the existing related art, the embodiment of the present application configures at least two power configuration tables. By using multiple power configuration tables, the corresponding power configuration table is switched according to different usage environments. The power configuration table after switching is the target power configuration table. Therefore, the transmit power corresponding to the wireless network communication connection can be adjusted according to the power configuration information in the target power configuration table, so as to use the lowest transmit power while ensuring communication. This solves the problem of excessive power or small coverage caused by using only one power configuration table to adjust transmit power in existing WiFi technology. It can reduce WiFi transmit power while ensuring communication quality, thereby reducing energy consumption and delaying the standby time of the AP and mobile terminals.
[0095] For example, the following describes the power setting of 11n as an example. By applying the power control method provided in the embodiment of the present application, multiple power configuration tables can be integrated into the WiFi system. For example, Figure 3The six power configuration tables shown are Power Table-1, Power Table 0, Power Table 1, Power Table 2, Power Table 3, and Power Table 4. The principle of setting the power tables is that from Power Table-1 to Power Table 0, the power of each standard is reduced by 3dB as a whole (taking 3dB as an example, the specific implementation is determined according to the actual project debugging), and from 0 to 1 is also reduced by 3dB as a whole (taking 3dB as an example, the specific implementation is determined according to the actual project debugging), and so on. In this way, if you drop from Power Table-1 to Power Table 4, the transmission power will drop by 15dB as a whole, which will greatly reduce the current during transmission and save energy.
[0096] Specifically, multiple power configuration tables are configured in the WiFi system in this example. Power table 0 is used by default. The transmit power bound to each rate can be configured according to the mainstream WiFi configuration information. This example does not impose any restrictions on this.
[0097] When the working environment is a clean environment with good signal and low interference, first reduce the power to power meter 1 and continue working for a period of time (set according to the debugging situation). You can continuously detect the current environment multiple times to determine whether the working environment is a clean environment with good environment. If the working environment is still very good, you can reduce it to power meter 2, and so on. In an excellent environment, you can reduce it to power meter 4. On the contrary, when the working environment is an interference environment with poor signal and large interference, such as when interference occurs in the use environment, you can first scan other channels to see if they are clean. If there is indeed no clean channel to switch to, and the current working environment is checked multiple times in a row and is an interference environment, it can be confirmed that there is long-term interference in the environment. Then you can upgrade the power meter, such as from power meter 4 to power meter 3, or from power meter 3 to power meter 2, and so on. If the operating environment is extremely harsh and has not improved for a long time, and there are no clean channels to switch to, consider upgrading the power meter to the highest level, Power Table-1. If the hardware supports it, you can also consider adding a Power Table-2. Based on Power Table-1, the power of each standard is increased by another 3dB, with a maximum power of 24dBm. This example does not impose any restrictions on use in extremely harsh environments.
[0098] In one example of the present application, the power table switching process may specifically include the following steps: initially using default power table 0, scanning the current operating environment, confirming the interference conditions of all channels, and selecting the cleanest channel. For example, if both the AP and the mobile terminal have the same power control system, the AP may initiate the power table switching process. If the AP does not have a new power control system, and only the mobile terminal has a new power control system, considering that the mobile terminal cannot determine the channel usage, the mobile terminal can scan the current environment for interference conditions and determine which power control table to use based on the scan results.
[0099] In addition, the power control method provided in this embodiment is significantly different from the real-time closed-loop power control method. It mainly detects the use environment for a long time to implement power meter switching according to the use environment. In order to ensure normal connection, when the use environment is good and the power needs to be adjusted downward, hourly environmental monitoring can be implemented to enable the power reduction mechanism when it is detected that the use environment is a clean environment for a long time, such as when the environment is detected to be very clean for 4 consecutive hours. On the contrary, when the clean environment becomes a harsh environment and the power needs to be increased, minute-level monitoring can be implemented. For example, if strong interference occurs continuously for 15 minutes, the power increase mechanism can be activated to ensure communication quality, and then the current during transmission can be reduced as much as possible while ensuring communication quality, saving energy consumption.
