[0027] Based on the description of the above background technology, the related technology also has the following situations:

[0028] As the level of vehicle intelligence increases, the number of electrical devices installed in vehicles is increasing. When the user performs corresponding control on the vehicle, the hard-wired signal of the corresponding function is triggered, and at least one corresponding electrical device is awakened according to the hard-wired signal. However, the user may only use one or more of the multiple electrical devices, but not all of them, resulting in unused electrical devices among the awakened electrical devices. However, even if the awakened electrical devices are not used, keeping them turned on will consume the power of the battery, which will cause the power of the battery pool to decrease, and will further trigger the charging of the power battery, consuming the power of the power battery. If the unused electrical devices are awakened for a long time for many times, the power of the battery and the power battery will be consumed extra, which may easily cause the whole vehicle to lose power.

[0029] The wake-up control method, device, electronic device and vehicle of the local network provided in the embodiment of the present application can determine the target network segment set corresponding to the wake-up signal after receiving the wake-up signal; determine the historical wake-up signal corresponding to the wake-up signal, and classify and self-learn at least one target network segment in the target network segment set according to the historical wake-up signal to obtain necessary network segments and non-essential network segments; wake up the necessary network segments, and monitor the local area network nodes corresponding to the necessary network segments in real time, and delay the sleep of the necessary network segments according to the flag status of the local area network nodes. After receiving the wake-up signal and determining the target network segment set corresponding to the wake-up signal, the self-learning of wake-up is performed by obtaining the corresponding historical wake-up signal, and the necessary network segments and non-essential network segments in the target network segment set are determined by self-learning, and the necessary network segments are awakened to meet the user's needs, and the power consumption is reduced by not awakening the non-essential network segments to avoid the whole vehicle from running out of power. And through delayed sleep to ensure to avoid frequent wake-ups, and reserve enough time for data processing and storage to ensure the accuracy of self-learning.

[0030] The following describes in detail the local network wake-up control method provided by the embodiments of the present application in conjunction with the accompanying drawings.

[0031] In some embodiments, Figure 1 As shown, a wake-up control method for a local network includes:

[0032] Step 101: In response to receiving a wake-up signal, determine a target network segment set corresponding to the wake-up signal.

[0033] In specific implementation, the application layer obtains the wake-up signal through the wake-up component and sends the wake-up signal to the bottom layer. The wake-up signal refers to a signal that can wake up the bottom layer from a dormant state. The preferred wake-up signal in this embodiment can be a signal that can wake up the bottom layer from a dormant state obtained by the wake-up component that is always in a working state. For example, the controller can be a body domain controller, the application layer can be the ASW in the Automotive OpenSystem Architecture (AUTOSAR) in the body domain controller, the bottom layer can be the BSW in the AUTOSAR in the body domain controller, the wake-up component can be the Sleep Model (SLP) in the ASW, and the wake-up signal can be a signal generated according to the Pin signal of the hard-wired transmission obtained by the wake-up component, or a signal generated according to the Network Management (NM) message transmitted by the communication network.

[0034] It is understandable that when the controller is in a dormant state, in order to obtain the wake-up signal of the controller, a part of the control unit (such as the wake-up component) will always be in working state. Optionally, the wake-up component can be a preset port component located on the vehicle side, or it can be a cloud-based remote component. For the cloud-based remote component, the wake-up network segment of each port can be configured on the vehicle remote service provider (Telematics Service Provider, TSP) platform. After the configuration is completed, the TSP sends the wake-up information through the telematics processor (Telematics BOX, T-BOX). After receiving the corresponding wake-up information, the T-BOX sends the wake-up information to the vehicle gateway. The vehicle gateway sends the corresponding wake-up information to the application layer of the corresponding controller to obtain the wake-up signal.

[0035] After the application layer receives the wake-up signal and sends it to the bottom layer, the bottom layer sends the wake-up signal to the application layer. The bottom layer refers to the software that can provide basic services, and the application layer refers to the software that can provide control algorithms. For example, the application layer can be the ASW in AUTOSAR in the body domain controller, and the BSW can send the Pin signal and NM message to the ASW through the interface module in the BSW. In this way, sending the wake-up signal to the application layer through the bottom layer avoids using the bottom layer to complete the matching of the wake-up signal, and realizes the step-by-step processing of the wake-up signal.

[0036] When performing network segment wake-up, the application layer first uses the pre-stored wake-up rules to match the wake-up signal to obtain a matching result. The wake-up rule refers to the rule that can filter the wake-up signal, and the matching result refers to the result obtained by matching the wake-up signal according to the wake-up rule. For example, when the wake-up signal is a Pin signal for opening the back door, the wake-up rule corresponding to the wake-up signal may be that the back door needs to be opened when there is a car key signal. The Pin signal for opening the back door can be matched with the presence of a car key signal.

[0037] Then, the application layer generates a wake-up instruction for the LAN node according to the matching result, and sends the wake-up instruction to the bottom layer, which uses the wake-up instruction to wake up the network segment in the dormant state.

[0038] Among them, the local area network refers to a unit that can provide communication functions to the bottom layer. For example, the local area network can include a local bus (Local Interconnect Network, LIN) network and a controller area network (Controller Area Network, CAN). The wake-up instruction refers to an instruction that can be used to wake up the network segment at the bottom layer, wherein the wake-up instruction can be generated by the wake-up function in the application layer. Among them, one network segment corresponds to one electrical device, each electrical device corresponds to at least one network segment, and a network segment can have multiple local area network nodes. As long as there is an awakened node among multiple local area network nodes, the corresponding network segment can be awakened; however, only when all local area network nodes are not awakened, the corresponding network segment can be put into sleep mode.

[0039] The wake-up signal is received through the application layer and sent to the bottom layer, avoiding the use of the bottom layer to complete the matching of the wake-up signal and realizing the step-by-step processing of the wake-up process; the application layer is used to match the wake-up signal according to the wake-up rule, and the wake-up instruction for the LAN node is obtained according to the matching result. The wake-up signal is filtered according to the wake-up rule to prevent the generation of wake-up instructions for the wake-up signal that does not meet the wake-up rule, thereby reducing the number of wake-up times of the network segment and thus reducing the power consumption of the whole vehicle.

[0040] However, the wake-up signal may need to wake up multiple network segments at the same time. For example, when the wake-up signal is a Pin signal for opening the back door, it is necessary to wake up the key detection device, the back door control device and the vehicle host. The key detection device is used to identify legal devices to ensure that the action of opening the back door is legal. The back door control device is used to unlock the back door's armed state and unlock the back door to ensure that the user can open the back door. The vehicle host is used to display the back door status and prompt the real-time status of the back door. The back door control network segment corresponding to the back door control device, the key detection network segment corresponding to the key detection device, and the host network segment corresponding to the vehicle host are all target network segments corresponding to the wake-up signal, and the target network segment set is (back door control network segment, key detection network segment, host network segment).

[0041] Step 102: determine a historical wake-up signal corresponding to the wake-up signal, and classify and self-learn at least one target network segment in the target network segment set according to the historical wake-up signal to obtain necessary network segments and non-essential network segments.

[0042] In specific implementation, if all network segments corresponding to the wake-up signal are directly awakened after receiving the wake-up signal, it may cause unnecessary power consumption. For example, when the wake-up signal is a Pin signal about opening the back door, it is necessary to wake up the back door control network segment, the key detection network segment and the host network segment at the same time, wherein the back door control device and the key detection device are devices that must be used when opening the back door of the vehicle to ensure the safety of the vehicle, so if you want to open the back door, you must wake up the back door control network segment and the key detection network segment. However, when the user does not actively operate the vehicle host, the function of the vehicle host is to display the status of the back door, and it is not a device that must be used after the door is opened, so the vehicle host may not be awakened after receiving the wake-up signal. However, if the user has the habit of using the vehicle host to control the back door to open or close automatically, at this time, if the vehicle host is not awakened, the user will not be able to directly control the back door of the vehicle through the vehicle host, and the user needs to manually wake up the vehicle host, which will bring a bad user experience to the user. Therefore, it is necessary to limit and control the wake-up process according to the user's usage habits.

[0043] Among them, it is necessary to use the historical wake-up signal corresponding to the wake-up signal to determine the user's usage habits for the wake-up signal, that is, to use the historical wake-up signal for classification self-learning to determine the user's usage habits. Among them, necessary network segments and non-essential network segments are used to reflect the user's usage habits. The necessary network segment indicates the network segment that the wake-up signal must wake up and the network segment that the user is accustomed to using. The non-essential network segment indicates the network segment that is not required to be woken up and the network segment that the user is not accustomed to using.

[0044] Exemplarily, when the wake-up signal is a Pin signal for opening the back door, the back door control network segment and the key detection network segment must be awakened in order to open the back door, and the back door control device and the key detection device will definitely be used automatically, so the back door control network segment and the key detection network segment are necessary network segments. However, when the user has not actively operated the vehicle host for many times, the host network segment is determined to be a non-essential network segment and does not need to be awakened to meet the user's usage habits. If the user actively operates the vehicle host for many times, it means that the user is accustomed to using the vehicle host to control the back door of the vehicle, and the host network segment is determined to be a necessary network segment and needs to be awakened to meet the user's usage habits. Therefore, it is necessary to classify and self-learn at least one target network segment in the target network segment set according to the historical wake-up signal to obtain necessary network segments and non-essential network segments to determine the user's vehicle usage habits for the wake-up signal to ensure that it will not affect the user's usage experience.

[0045] Step 103: Wake up the necessary network segment, monitor the LAN nodes corresponding to the necessary network segment in real time, and delay the sleep of the necessary network segment according to the flag bit status of the LAN node.

[0046] In specific implementation, after classifying the target network segments corresponding to the wake-up signal, the necessary network segments and non-essential network segments representing the user's usage habits can be obtained. The non-essential network segments indicate that the user is not used to using the power-consuming equipment corresponding to the non-essential network segments after triggering the corresponding wake-up signal, so there is no need to wake up the non-essential network segments. The necessary network segments indicate the network segments that must be used when the wake-up signal function is implemented and that the user is used to using. Therefore, only the necessary network segments need to be awakened to meet the user's usage habits while realizing the usage function. That is, the user's needs can be met by awakening the necessary network segments, and the power consumption can be reduced by not awakening the non-essential network segments to avoid the whole vehicle from running out of power.

[0047] For example, when the user opens the back door, he does not open the car door and does not start the vehicle (the power is not on). Opening the back door usually wakes up the back door control segment CAN1, the key detection segment CAN2, and the host segment CAN3, among which CAN3 is the segment where the vehicle host is located. Waking up CAN3 is to display the status of the back door. After self-learning of historical big data, it is determined that CAN1 and CAN2 are necessary segments and CAN3 is a non-essential segment. When the user opens the back door again, only CAN1 and CAN2 are woken up, and CAN3 is not woken up, effectively reducing energy consumption.

[0048] After waking up the necessary network segment, it is necessary to continue to monitor the information of the dormant necessary network segment to determine when to put the necessary network segment into dormancy. Since a network segment corresponds to at least one LAN node, and any LAN node is awakened, the network segment is awakened. However, the network segment can only be put into dormancy when all LAN nodes corresponding to the network segment are in dormancy.

[0049] Exemplarily, taking the key detection network segment corresponding to the key detection device as an example, when opening the trunk, it is necessary to detect a legal key to determine whether it is a legal opening of the back door. When opening the driver's door, it is necessary to detect a legal key to determine whether it is a legal opening of the driver's door. The key detection network segment includes at least a local area network node 1 corresponding to the back door and a local area network node 2 corresponding to the driver's door.

[0050] When LAN node 1 is awakened, it means that the user needs to open the back door, and a legal key detection is required to prevent the back door from being opened illegally, and the key detection network segment needs to be awakened; when LAN node 2 is awakened, it means that the user needs to open the driver's door, and a legal key detection is required to prevent the driver's door from being opened illegally, and the key detection network segment needs to be awakened. Therefore, as long as any LAN node corresponding to the network segment is awakened, the network segment can be awakened.

[0051] When the key detection segment is dormant, if both LAN node 1 and LAN node 2 are awakened at the beginning, and after a period of time it is determined that LAN node 1 has no network maintenance source, LAN node 1 is dormant. At this time, LAN node 2 still remains in the awake state. If the key detection segment is closed, the legal key detection for opening the driver's door will not be possible, resulting in danger in opening and closing the driver's door. Therefore, the key detection segment needs to be kept in the awake state until it is determined that LAN node 2 has no network maintenance source, and LAN node 2 is dormant. At this time, all LAN nodes corresponding to the key detection segment are dormant, and it can be determined that there is no need to use the key detection segment, and the key detection segment can be dormant.

[0052] Therefore, after waking up the necessary network segment, it is necessary to monitor the LAN nodes corresponding to the necessary network segment in real time, and determine the status of each LAN node according to the flag status of the LAN node, and when all LAN nodes are in sleep mode, turn on the delayed sleep control of the necessary network segment, that is, sleep the necessary network segment after the preset delay time, and ensure that the application layer can process the signal storage work within the delay time, so as to use the wake-up control process data as a new historical wake-up record, and provide output for the subsequent determination of user habits. Through delayed sleep, frequent wake-ups are avoided, and sufficient time is reserved for data processing and storage to ensure the accuracy of classification self-learning.

[0053] In summary, the wake-up control method for the local network provided in the embodiment of the present application can, after receiving the wake-up signal and determining the target network segment set corresponding to the wake-up signal, perform self-learning of the wake-up by acquiring the corresponding historical wake-up signal, and determine the necessary network segments and unnecessary network segments in the target network segment set through self-learning, and meet user needs by waking up the necessary network segments, and reduce power consumption by not waking up the unnecessary network segments to avoid power shortage of the whole vehicle. And by delaying sleep to ensure that frequent wake-ups are avoided, and sufficient time is reserved for data processing and storage to ensure the accuracy of self-learning.

[0054] In some embodiments, Figure 2 As shown, at least one target network segment in the target network segment set is classified and self-learned according to the historical wake-up signal to obtain necessary network segments and non-essential network segments, including:

[0055] Step 201: Determine a historical wake-up record corresponding to a historical wake-up signal.

[0056] In the specific implementation, when performing classification self-learning, historical data is needed to determine the user's usage habits of the wake-up signal. First, the historical wake-up signal corresponding to the wake-up signal is determined. If the wake-up signal this time is a wake-up signal for opening the back door, then the historical wake-up signal is the previous multiple, or even all, historical back door wake-up signals. Each historical back door wake-up signal corresponds to an operation record when the user opens the back door once, then the historical wake-up record corresponding to the historical wake-up signal is the user's operation record when the back door was opened multiple times or even all times before. Based on the wake-up record, the user's usage habits when opening the back door can be determined to avoid invalid wake-ups.

[0057] Step 202: Classify and self-learn the target network segments according to the historical wake-up records to obtain necessary network segments and unnecessary network segments.

[0058] In specific implementation, if there is data directly reflecting the user's usage habits in the historical wake-up records, classification self-learning can be performed directly based on the data, and the target network segment has been classified into necessary network segments and non-essential network segments. Exemplarily, if there is direct data on the user's use of the back door in the historical wake-up records, for example, the probability of the user using the vehicle host is 1%, and the probability of not using the vehicle host is 99%, then the host network segment can be directly determined as a non-essential network segment. The data that directly represents the back door usage habits can be the data calculated during the last delayed exit. When using it this time, the data can be directly called for row classification self-learning. If there is no data that directly represents the user's usage habits, it is necessary to classify the target network segment according to the historical wake-up records. Self-learning has completed the classification of necessary network segments and non-essential network segments.

[0059] In some embodiments, Figure 3As shown in the figure, the target network segment is classified according to the historical wake-up records to obtain necessary network segments and unnecessary network segments, including:

[0060] Step 301: Determine wake-up usage information of each target network segment in a target network segment set according to historical wake-up records.

[0061] In specific implementation, it is necessary to determine how the user uses the vehicle each time the user receives a historical wake-up signal that is the same as the current wake-up signal based on the historical wake-up record, so it is necessary to determine the wake-up usage information of each target network segment in the target network segment set based on the historical wake-up record. Exemplarily, when the wake-up signal is a Pin signal for opening the back door, the target network segment set is (back door control network segment, key detection network segment, host network segment). Statistics are separately made on how the user uses the back door control network segment, key detection network segment, and host network segment each time a Pin signal for opening the back door is received, wherein the back door control network segment and the key detection network segment are network segments automatically used by the vehicle to ensure safety, so the back door control network segment and the key detection network segment wake-up usage information is 100% use of the back door control network segment and the key detection network segment.

[0062] The function of the vehicle host corresponding to the host network segment is to display the status of the back door. If the user opens the back door outside the car and takes out the required items, and then manually closes the back door directly outside the car, it means that the user is not used to using the vehicle host to control the back door after opening the back door, but is used to manually opening or closing the back door. At this time, it can be determined that the usage information of the host network segment is the record information of not using the host network segment once. If the user opens the back door through the vehicle host in the car, and / or returns to the car after taking the items and controls the closing of the back door through the vehicle host, it can be determined that the user is used to using the vehicle host to control the opening and closing of the back door. At this time, it can be determined that the usage information of the host network segment is the record information of using the host network segment once. The wake-up usage information includes the record information of how the user used the target network segment each time before, and the user's usage habits can be determined based on the wake-up usage information.

[0063] Step 302: Classify and self-learn the target network segments according to the wake-up usage information to obtain necessary network segments and non-essential network segments.

[0064] In some embodiments, step 302 includes:

[0065] Step 3021: Determine the total number of wake-up times for each target network segment according to the wake-up usage information.

[0066] In specific implementation, the wake-up usage information records how the user uses each target network segment each time a signal identical to the wake-up signal is received. The total number of record information corresponding to each target network segment is the total number of wake-up times for the target network segment. The total number of wake-up times can also be directly understood as the total number of historical wake-up signals that are identical to the current wake-up signal.

[0067] Step 3022: Determine the wake-up usage count for each target network segment according to the wake-up usage information.

[0068] In specific implementation, the wake-up usage information includes record information of whether the user uses each target network segment after receiving a historical wake-up signal each time, and the wake-up usage count is the number of times the user uses the target network segment in the wake-up usage information.

[0069] Step 3023: Determine the ratio of the wake-up usage times to the total wake-up times as the wake-up usage probability of the target network segment.

[0070] In specific implementation, the wake-up usage probability represents the proportion of the wake-up usage times of the target network segment in the total wake-up times. For example, when the wake-up signal is a Pin signal about opening the back door, if 1000 historical Pin signals of opening the back door are obtained, the total wake-up times are 1000 times. At this time, the target network segment set is (back door control network segment, key detection network segment, host network segment), then the total wake-up times of each target network segment in the target network segment set are 1000 times. Since the back door control network segment and the key detection network segment are automatically used when opening the car door, the wake-up usage times of the back door control network segment and the key detection network segment are both 1000 times. If the user only controls the back door through the vehicle host 10 times in the history of 1000 times, then the wake-up usage times of the host network segment are 10 times. Then the wake-up usage probability of the back door control network segment and the key detection network segment is 100%. The wake-up usage probability of the host network segment is 10 / 1000=1%.

[0071] Step 3024: Determine the target network segment whose wake-up usage probability is greater than or equal to a preset probability threshold as a necessary network segment.

[0072] In specific implementation, the probability threshold is a judgment condition for distinguishing whether it is a commonly used network segment. For example, the probability threshold is 2%. When the probability of waking up is greater than or equal to the preset probability threshold, it means that the user occasionally uses the corresponding target network segment. The target network segment cannot be directly not woken up. The target network segment needs to be determined as a necessary network segment, such as the back door control network segment and the key detection network segment with a usage probability of 100%.

[0073] Step 3025: Determine the target network segment whose wake-up usage probability is less than a preset probability threshold as a non-essential network segment.

[0074] In specific implementation, when the wake-up usage probability is less than the preset probability threshold, it means that the user hardly uses the corresponding target network segment, and not waking up the target network segment will not affect the user's normal use, which is in line with the user's usage habit of not using the target network segment. In this case, the target network segment is determined as a necessary network segment, such as a host network segment with a usage probability of 1%.

[0075] In some embodiments, Figure 4 As shown, the necessary network segments are delayed to sleep according to the flag status of the LAN node, including:

[0076] Step 401: Determine the flag status of each LAN node.

[0077] In specific implementation, after waking up the necessary network segment, it is necessary to continue to monitor the information of the necessary network segment in hibernation to determine when to put the necessary network segment into hibernation, wherein, since a network segment corresponds to at least one LAN node, and any LAN node is awakened, the network segment is awakened. However, the network segment can only be put into hibernation when all LAN nodes corresponding to the network segment are in hibernation. After waking up the necessary network segment, it is necessary to monitor the LAN nodes corresponding to the necessary network segment in real time, and determine the status of each LAN node according to the flag status of the LAN node. Among them, the flag status of the LAN node includes a reset state and a set state. The reset state indicates that the flag bit is cleared to sleep, and the flag bit is set to 0, corresponding to the sleep state of the LAN node. The set state indicates that the flag bit is awakened, and the flag bit is set to 1, corresponding to the wake-up state of the LAN node.

[0078] Step 402: In response to a flag bit in a set state being present in a plurality of flag bit states, determining that a delayed sleep condition is not satisfied.

[0079] In specific implementation, if there is a set flag in multiple flag states, it means that there is a LAN node in the awake state, which means that there is a network maintenance source in the target network segment, and the awake state of the target network segment needs to be maintained, and it is determined that the delayed sleep condition is not met.

[0080] Step 403: In response to the multiple flag bits being in the reset state, it is determined that the delayed sleep condition is met, and after a preset delay time, the necessary network segments are put into sleep.

[0081] In specific implementation, if multiple flag bits are in reset state, it means that all LAN nodes are in sleep state, indicating that there is no network maintenance source in the target network segment, and the target network segment needs to be put into sleep state to reduce energy consumption, and determine whether the delayed sleep condition is met. After determining that the delayed sleep condition is met, it is necessary to put the necessary network segment into sleep state after a preset delay time. The delay time can ensure that the application layer can process the signal storage work within the delay time, so as to use the wake-up control process data of this time as a new historical wake-up record, and provide output for the subsequent determination of user habits. Delayed sleep is used to avoid frequent wake-ups, and sufficient time is reserved for data processing and storage to ensure the accuracy of classification self-learning.

[0082] In some embodiments, Figure 5 As shown, before the necessary network segments are put into sleep mode, the following are also included:

[0083] Step 501: Monitor the first type of control instructions for necessary network segments in real time.

[0084] In specific implementation, the first type of control instruction is a control instruction for using functions related to the necessary network segment. During the waiting stage of delayed dormancy, the first type of control instruction for the necessary network segment can be monitored to determine whether the user needs to continue to use the function corresponding to the necessary network segment.

[0085] Step 502: in response to detecting the first type of control instruction, interrupting the dormancy of the necessary network segment, and delaying the dormancy of the necessary network segment after the first type of control instruction is executed.

[0086] In specific implementation, if the user actively uses the function corresponding to the necessary network segment again, the first type of control instruction will be detected, which means that the user does not have the need to sleep the target network segment temporarily and needs to continue to use the target network segment. In this case, the sleep of the necessary network segment needs to be interrupted, and the necessary network segment needs to be delayed to sleep after the first type of control instruction is executed. For example, the user manually opens the back door, takes out the items and then closes the back door. At this time, the delayed waiting stage of the delayed sleep back door control network segment and the key detection network segment will be entered. At this time, the user finds that there are still items that have not been taken out. The user manually opens the back door again. At this time, the first type of control instruction will be detected, and the sleep of the necessary network segment needs to be interrupted to ensure that the user continues to use the back door, avoiding frequent wake-up and sleep of non-essential network segments and reducing power consumption.

[0087] In some embodiments, Figure 6 As shown, before the necessary network segments are put into sleep mode, the following are also included:

[0088] Step 601: monitor the second type of control instructions for non-essential network segments in real time.

[0089] In specific implementation, the second type of control instruction is a control instruction for using functions related to non-essential network segments. Non-essential network segments indicate that users are not used to using the corresponding functions. However, users may change their usage habits at some point and choose to use the functions of non-essential network segments. At this time, when users use the functions of non-essential network segments, the second type of control instruction will be triggered.

[0090] Step 602: In response to detecting the second type of control instruction, wake up the non-essential network segment and interrupt the sleep of the essential network segment.

[0091] During specific implementation, if the second type of control instructions are detected, it means that the user has temporarily changed his usage habits and needs to use related functions of non-essential network segments. At this time, it is necessary to wake up the non-essential network segments and interrupt the sleep of the necessary network segments, and subsequently delay the sleep of both the necessary and non-essential network segments.

[0092] Step 603: monitor the LAN nodes corresponding to the necessary network segments and the non-essential network segments in real time, and control the necessary network segments and the non-essential network segments to perform delayed sleep according to the flag bit status of the LAN nodes.

[0093] In specific implementation, the non-essential network segment after awakening has temporarily become a necessary network segment, so the sleep control process is consistent with the necessary network segment, and delayed sleep control is performed. At this time, the LAN nodes corresponding to the necessary network segment and the non-essential network segment are monitored simultaneously. Only when all these LAN nodes are cleared and reset, the necessary network segment and the non-essential network segment are controlled to delay sleep. Energy saving is achieved by not awakening the non-essential network segment while ensuring the use of the non-essential network segment function, providing users with a better user experience.
