[0050] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] It should be understood that, when used in this specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0052] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0053] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0054] As used in this specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrases "if determined" or "if [described condition or event] is detected" may be interpreted, depending on the context, as "once determined," "in response to determination," "once [described condition or event] is detected," or "in response to detection of [described condition or event]."

[0055] Furthermore, in the description of this application, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0056] In this embodiment, the network device can be a router or access point (AP), which typically has multiple network ports. As the number of network port connections increases, the power consumption of the network device also increases. When the power consumption of the network device reaches its rated power, it is considered to be under full load. At this time, the output current of the power adapter will continuously increase with the rise in temperature, and may even exceed the overcurrent point of the power adapter, thereby causing the network device to restart. Here, full load means that the chip temperature of the network device reaches a preset threshold and packets are transmitted at the maximum transmission power of the network device. At this time, multiple local area network (LAN) ports and wide area network (WAN) ports are running current.

[0057] To reduce the output current of the power adapter when the network device is under high temperature and full load, and to ensure that it does not exceed the overcurrent point of the power adapter, the existing technology adopts a "one-size-fits-all" approach when adjusting the transmission power of the network device. That is, it does not consider the number of network port connections, but directly sets the transmission power of the network device to a fixed value. Although this method can ensure that the output current of the power adapter does not exceed the overcurrent point of the power adapter when the network device is under high temperature and full load, it does not take into account that when the number of network port connections decreases, the transmission power of the network device does not increase accordingly, resulting in excessive loss of wireless performance of the network device.

[0058] Based on this, this application provides a power adjustment method that dynamically adjusts the transmission power of the network device according to the number of network port connections, thereby ensuring that the output current of the power adapter of the network device does not exceed the overcurrent point of the power adapter, while minimizing the loss of wireless performance.

[0059] This application can be applied to network devices with at least two network ports, such as network devices with two network ports, network devices with three network ports, network devices with four network ports, or network devices with more than one network port. This application does not specifically limit the number of network ports of a network device. The embodiments of this application take a network device with four network ports as an example.

[0060] Please see Figure 1 One embodiment of a power regulation method in this application may include:

[0061] Step S101: Obtain the current number of network port connections of the network device.

[0062] In one specific implementation of this application embodiment, the network port of the network device can be determined to be in a connected state based on whether the network port is occupied. If the network port of the network device is occupied, it is considered to be in a connected state. If the network port of the network device is not occupied, it is considered to be in a disconnected state. The number of occupied network ports is the current number of network port connections of the network device in this application embodiment.

[0063] Step S102: Determine the target maximum transmit power of the network device.

[0064] The target maximum transmit power is the maximum transmit power corresponding to the current number of network port connections.

[0065] Before determining the target maximum transmit power of the network device, a power mapping relationship needs to be pre-set. This relationship records the maximum transmit power corresponding to different numbers of network port connections. The maximum transmit power is the maximum transmit power achievable by the network device when the output current of the power adapter does not exceed the power adapter's overcurrent limit. Since the maximum transmit power under these conditions varies depending on the number of network port connections, it is necessary to record the maximum transmit power corresponding to different numbers of network port connections.

[0066] In one specific implementation of this application, the maximum transmit power recorded in the power correspondence relationship corresponding to different numbers of network port connections is the transmit power of the network device operating at full load under different numbers of network port connections. The process of setting the power correspondence relationship is as follows: First, the network device is operated at full load under different numbers of network port connections. Based on the test results, the maximum transmit power corresponding to different numbers of network port connections is determined. Then, the number of network port connections and their corresponding maximum transmit power are recorded in the power correspondence relationship.

[0067] For ease of description, this section uses any number of network port connections (denoted as the specified number of network port connections) as an example to explain in detail the process of setting the power correspondence. The network device is operated at full load with its rated transmit power. The output current of the network device's power adapter is obtained at this time. The output current of the power adapter is compared with a preset current threshold. The current threshold can be set according to the overcurrent point of the power adapter, for example, set to the overcurrent point, 0.9 times the overcurrent point, or 0.8 times the overcurrent point, etc. This embodiment does not specifically limit this, but the overcurrent point is preferred. If the output current of the power adapter is greater than the current threshold, the transmit power of the network device is gradually reduced according to a preset adjustment step size until the output current of the power adapter is less than or equal to the current threshold. If the output current of the power adapter is less than or equal to the current threshold, the current transmit power of the network device is determined as the maximum transmit power corresponding to the specified number of network port connections. By iterating through each number of network port connections in the above manner, the number of network port connections and their corresponding maximum transmit power can be obtained, and each correspondence is recorded in the power correspondence. The adjustment step size can be set according to actual conditions, and this embodiment does not specifically limit this.

[0068] Taking a network device with two network ports as an example, the network device first operates at full load with its rated transmission power. The output current of the network device's power adapter is then obtained. If the output current of the network device's power adapter is greater than the current threshold of the network device's power adapter, the transmission power of the network device is reduced by one adjustment step, and the output current of the network device's power adapter is obtained again after this reduction in transmission power. If the output current of the network device's power adapter is still greater than the current threshold, the transmission power of the network device is further reduced by the first adjustment step until the output current of the network device's power adapter is less than or equal to the current threshold. Suppose that when the transmission power of the network device is reduced to a certain value, the output current of the network device's power adapter is less than or equal to the current threshold. At this point, this value is taken as the maximum transmission power corresponding to the number of network ports connected to the network device being two, and the correspondence between the number of network ports connected to two and this value is recorded in the power correspondence relationship.

[0069] After obtaining the current number of network port connections of the network device, the maximum transmission power corresponding to the number of network port connections that is the same as the current number of network port connections can be found in the preset power correspondence, and this maximum transmission power is determined as the target maximum transmission power of the network device.

[0070] Taking the first, second, third, and fourth transmit powers as the maximum transmit powers corresponding to different numbers of network port connections, the power correspondence is as follows: Figure 2As shown, the maximum transmission power corresponding to four network ports is the first transmission power, the maximum transmission power corresponding to three network ports is the second transmission power, the maximum transmission power corresponding to two network ports is the third transmission power, and the maximum transmission power corresponding to one network port is the fourth transmission power. When the network device has four network ports, the maximum transmission power corresponding to it in the power mapping is the first transmission power, and the target maximum transmission power of the network device is the first transmission power. When the network device has three network ports, the maximum transmission power corresponding to it in the power mapping is the second transmission power, and the target maximum transmission power of the network device is the second transmission power. When the network device has two network ports, the maximum transmission power corresponding to it in the power mapping is the third transmission power, and the target maximum transmission power of the network device is the third transmission power. When the network device has one network port, the maximum transmission power corresponding to it in the power mapping is the fourth transmission power, and the target maximum transmission power of the network device is the fourth transmission power. The first, second, third, and fourth transmission powers increase sequentially. It should be noted that the above content is only an example in the embodiment of this application. The maximum transmission power corresponding to the number of network ports of the network device should be set according to the actual situation, and this embodiment of the application does not make specific limitations in this regard.

[0071] Step S103: Adjust the transmission power of the network device according to the target's maximum transmission power.

[0072] The transmission power of a network device includes the transmission power of data frames, the transmission power of management frames, and / or the transmission power of control frames. Therefore, adjusting the transmission power of a network device means adjusting the transmission power of data frames, management frames, and / or control frames.

[0073] When adjusting the transmission power of a network device, the target maximum transmission power is compared with the transmission power of the network device. If the target maximum transmission power is less than the transmission power of the network device, the transmission power of the network device is adjusted to the target maximum transmission power; if the target maximum transmission power is greater than the transmission power of the network device, the transmission power of the network device is adjusted back.

[0074] Taking a data frame with its transmission power adjusted to the fifth transmission power as an example, where the fifth transmission power is greater than the third transmission power but less than the fourth transmission power, let's assume the network device's transmission power is the fifth transmission power when it has only one network port connection. When the number of network port connections increases from one to three, the network device's target maximum transmission power becomes the second transmission power. Since this target maximum transmission power is less than the data frame transmission power, the data frame transmission power needs to be reduced to the second transmission power. When the number of network port connections decreases from three to two, the network device's target maximum transmission power increases to the third transmission power. Since this target maximum transmission power is still less than the data frame transmission power, the data frame transmission power is set to the third transmission power. When the number of network port connections decreases from two to one, the network device's target maximum transmission power increases to the fourth transmission power. Since this target maximum transmission power is greater than the data frame transmission power, the data frame transmission power is reverted back to the fifth transmission power. The adjustment methods for management frame transmission power and control frame transmission power are the same as those for data frame transmission power and will not be repeated here.

[0075] In one specific implementation of this application, a method for adjusting the transmission power of a network device is also provided. The first adjustment method is to adjust the transmission power of the network device according to the signal adjustment level of the network device, and the second adjustment method is to adjust the transmission power of the network device according to the target power register of the network device.

[0076] When adjusting the transmission power of a network device based on its signal adjustment level, multiple signal adjustment levels can be preset. These levels progressively decrease the transmission power in descending order, with a preset difference between each adjacent adjustment level. This preset difference can be set according to actual conditions, and this embodiment does not impose a specific limitation. When the network device detects a change in the number of network port connections, it can adjust the signal adjustment level to change the transmission power accordingly. For example, when the number of network port connections decreases, the signal adjustment level can be increased to increase the transmission power; conversely, when the number of network port connections increases, the signal adjustment level can be decreased to reduce the transmission power. This method allows for finer-grained transmission power adjustment, effectively improving the accuracy of transmission power adjustment.

[0077] When the network device's transmit power is adjusted based on its target power register, if the number of network port connections exceeds a set threshold, the network device can read the target maximum transmit power from the power correspondence upon power-up, set it in the power register, and then adjust the transmit power through the power register. For example, taking a threshold of one network port connection as an example, when the number of network port connections is one, the network device will not adjust the power register. When the number of network port connections increases from one to two, the network device can read the target maximum transmit power corresponding to the number of network port connections being two, use this target maximum transmit power to modify the power set in the power register, and then adjust the transmit power through the power register.

[0078] It should be noted that the above adjustment method is only a preferred embodiment in the embodiments of this application. In practical applications, other methods can also be used to adjust the transmission power of network devices, and the embodiments of this application do not specifically limit this.

[0079] In summary, the method described in this application obtains the current number of network port connections of a network device; determines the target maximum transmit power of the network device; wherein the target maximum transmit power is the maximum transmit power corresponding to the current number of network port connections; and adjusts the transmit power of the network device according to the target maximum transmit power. Through this application, the transmit power of the network device can be dynamically adjusted according to the current number of network port connections, thereby minimizing the performance loss of the network device while ensuring that the output current of the power adapter does not exceed the limit.

[0080] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
