Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

At present, intelligent networking and cooperative service completion among a plurality of electronic devices become a trend. After a plurality of electronic devices capable of establishing a mutual trust relationship are discovered mutually, a network can be automatically formed, which is called an intelligent network. For example, if a plurality of electronic devices log in the same Account (that is, account IDs are the same), or a user performs a binding and authentication process on the plurality of electronic devices (for example, the plurality of electronic devices are bound by a pin code or a Quick Response (QR) code), a mutual trust relationship is established between the plurality of electronic devices.

In the embodiment of the application, for a plurality of electronic devices with trust relationships in the near field communication range, one electronic device maintains a logical connection with other electronic devices, and the states and information of the electronic devices can be synchronized when the system runs. These mutually trusted electronic devices may form an intelligent network.

It should be noted that the intelligent network is only one name of the network according to the embodiment of the present application, and the network according to the embodiment of the present application may have other names, which is not limited.

The plurality of electronic devices in the intelligent network support local short-range communication, for example, may support a short-range wireless communication method such as bluetooth, wi-Fi, or Near Field Communication (NFC), or support a short-range wired communication method such as Universal Serial Bus (USB). For an exemplary networking schematic of a smart network, see fig. 1A. As shown in fig. 1A, bluetooth Low Energy (BLE) communication modes are supported between the large screen and the mobile phone, between the large screen and the smart watch (watch for short), between the watch and the earphone, and between the mobile phone and the earphone. A Wi-Fi communication mode is supported between the mobile phone and the intelligent sound box (a sound box for short).

After the networking of the intelligent network is completed, the electronic equipment in the intelligent network is on line. Specifically, during or after mutual discovery, the multiple electronic devices may exchange information (including identity information of the electronic devices, etc.) with each other to notify the identities of the online electronic devices of each other. Then, the electronic devices in the intelligent network can perform online detection through the heartbeat packet so as to know the conditions of the online electronic devices. In embodiments of the present application, online means that the electronic device can be detected by heartbeat packets, not necessarily indicating that there is an established network connection or data channel.

For example, after the electronic device 1 in the intelligent network sends the heartbeat packet to the electronic device 2, if the heartbeat response message sent by the electronic device 2 is received within the preset time period, the electronic device 2 is considered to be online. The online electronic equipment in the intelligent network can initiate service data transmission at any time, so that service processing can be completed quickly, directly and cooperatively. If the electronic device 1 does not receive the heartbeat response message sent by the electronic device 2 within the preset time length, it is determined that the electronic device 2 is offline. The electronic devices in the intelligent network can also notify the identity information of the offline device to each other, so that each electronic device can know the current online device and the offline device.

The embodiment of the application provides an online detection method, which can control the sending opportunity and/or the receiving opportunity of a heartbeat packet based on the clock difference between sending end electronic equipment and receiving end electronic equipment in a network, so that the receiving end electronic equipment receives the heartbeat packet when being in a window receiving state, the receiving efficiency of the heartbeat packet can be improved, the receiving and sending times and the time length of the heartbeat packet are reduced, the power consumption of the electronic equipment is reduced, and low-power-consumption, quick, timely and accurate online detection can be realized on a plurality of electronic equipment in the network based on the heartbeat packet. The window of the receiving-end electronic device is used for receiving the heartbeat packet, and may be referred to as a receiving window, for example, specifically, a scanning window of the receiving-end electronic device.

For example, the electronic device in the smart connectivity network may be a mobile terminal such as a mobile phone, a tablet computer, a wearable device (e.g., a headset, a smart watch, a smart band, smart glasses, etc.), a smart home device (e.g., a large screen, a sound box, a smart lamp, etc.), an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, or a Personal Digital Assistant (PDA), and the embodiments of the present application do not limit the specific type of the electronic device.

The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

In the embodiment of the present application, the processor 110 operates the instruction stored in the internal memory 121, so that the electronic device 100 in the intelligent network can control the sending opportunity and/or the receiving opportunity of the heartbeat packet based on the clock difference between the electronic devices, and the electronic device at the receiving end receives the heartbeat packet when being in the window receiving state, thereby improving the receiving efficiency of the heartbeat packet, reducing the receiving and sending times and duration of the heartbeat packet, and reducing the power consumption of the electronic device, so that the fast, timely, and accurate online detection of the plurality of electronic devices in the network can be realized based on the heartbeat packet.

The heartbeat packet based online detection method provided by the embodiment of the present application will be explained below with reference to the accompanying drawings.

Electronic devices in a intelligently connected network may also be referred to as nodes. In the embodiment of the application, the nodes of the intelligent connection network have an upper-level relationship and a lower-level relationship, and the upper-level node can send a heartbeat packet to the lower-level node so as to detect whether the lower-level node is on line or not. The superior and inferior relations between the nodes can be determined according to the information of the nodes and/or the mutual relation between the nodes and other factors. In an intelligent network, there may be one or more subordinate nodes of a node.

For example, the information of the node itself may include one or more of network capability information, processing capability information, network quality, power information, motion information, service information, and Service Set Identifier (SSID), etc. The network capability information may include at least one of a network connection supported by the node, a maximum bandwidth supported by the network connection supported by the node, and connection information of the network connection supported by the node (e.g., a port number, a Media Access Control (MAC) address or an Internet Protocol (IP) address). The processing capability information of the node indicates the processing capability of the node, including, for example, the power consumption, the chip processing capability, and the memory of the node.

For example, the interrelationship between nodes may include network topology relations and the like. The network topology relationship includes the network connection mode supported between the nodes, the communication path between the nodes, and the like.

For example, the upper and lower level relationships between the nodes may be determined according to the weights of the nodes and the network topology relationship between the nodes. The weight of the node can be determined by the node according to the network capability information of the node and the processing capability information of the node, for example, the weight of the node with high power consumption, insensitivity to power consumption, good chip processing capability, large memory and strong network capability is high; conversely, nodes with low power consumption, sensitivity to power consumption, poor chip processing capability, small memory, and weak network capability have low weights.

In the embodiment of the application, the nodes in the intelligent network may include a central node, a primary node, a secondary node, and the like according to a relationship from an upper level to a lower level. The central node is the node at the uppermost level, and only the lower level node and no upper level node exist. The lower nodes of the central node are called primary nodes, and the central node is the upper node of the primary nodes; the lower nodes of the first-level nodes are called second-level nodes, and the first-level nodes are the upper-level nodes of the second-level nodes; in analogy, the intelligent network may further comprise a third level node or a fourth level node, etc. The number of the levels of the nodes included in the intelligent network is not limited in the embodiment of the application. An intelligent network typically includes a central node and may have one or more subordinate nodes belonging to different hierarchical levels. Further, if a node has both an upper node and a lower node, the node may also be referred to as an intermediate node. A node may also be referred to as a tail node if it has only an upper node and no lower nodes.

For example, in the intelligent network shown in fig. 1A, bluetooth BLE network connection is supported between the large screen and the mobile phone, and between the large screen and the watch. The Bluetooth BLE network connection mode is supported between the mobile phone and the earphone, and the Wi-Fi network connection mode is supported between the mobile phone and the sound box. According to the factors such as weight, network topological relation and the like, the electronic equipment determines that the central node is a large screen, the large screen is a superior node of a mobile phone and a watch, and the mobile phone is a superior node of an earphone and a sound box. Correspondingly, the mobile phone and the watch are subordinate nodes of the large screen, and the earphone and the sound box are subordinate nodes of the mobile phone.

In the intelligent network shown in fig. 1A, it is known from the network topology that network connections are supported between the mobile phone and the headset and between the watch and the headset, but the headset acts as a lower node of the mobile phone and does not act as a lower node of the watch depending on factors such as the weight of the node.

In the intelligent network, a large screen is a central node, a mobile phone and a watch are primary nodes, and an earphone and a sound box are secondary nodes. For example, the hierarchical relationship between the upper and lower nodes in the intelligent networking network can be seen in fig. 2. The mobile phone may also be referred to as an intermediate node, and the watch, the earphone, and the sound box may also be referred to as a tail node.

In the embodiment of the application, after networking is completed, one or more network connection modes can be supported between any two electronic devices in the intelligent connection network, but the network connection is not necessarily established between the electronic devices. The network connection mode supported between the electronic devices may be a short-range wireless network connection mode, a wired network connection mode, or the like. The wireless network connection mode that can perform online detection by using the method provided by the embodiment of the present application may be referred to as a first network connection mode. For example, the first network connection mode may be a short-range wireless network connection mode supporting an air interface scanning mechanism. The other network connection method than the first network connection method may be referred to as a second network connection method. For example, the bluetooth BLE may be a first network connection mode, the USB may be a second network connection mode, and the Wi-Fi, the bluetooth Basic Rate (BR), the bluetooth enhanced rate (EDR), or the like may be the first network connection mode or the second network connection mode.

In the intelligent connection network, information such as heartbeat packets and the like can be interacted between two electronic devices supporting the first network connection mode through the communication mode of the air interface sending and receiving window. That is, the sending-end electronic device sends a message through the air interface, and the receiving-end electronic device receives the message in the receiving window. For example, the air interface transmission mode may be a broadcast or unicast mode, and the receiving window may be a scanning window.

If the first network connection mode is not supported between the two electronic devices in the intelligent connection network and the second network connection mode is supported, information such as heartbeat packets and the like is interacted based on the second network connection mode, so that online detection is carried out.

In this embodiment, the priority of the first network connection mode may be higher than that of the second network connection mode. If the two electronic devices in the intelligent network support both the first network connection mode and the second network connection mode, information such as heartbeat packets and the like is interacted through the communication mode of the air interface sending and receiving window based on the first network connection mode, so that online detection is carried out.

The scheme provided by the embodiment of the application can be started from the central node of the intelligent network, and the heartbeat packet is sent from the superior node to the subordinate node step by step, so that the electronic equipment in the intelligent network is uniformly detected on line, and the online and offline states of the electronic equipment in the intelligent network are uniformly determined, so that the service can be rapidly, directly and cooperatively completed by using the online electronic equipment.

In the intelligent connection network, the upper and lower nodes supporting the first network connection mode may perform control based on the clock difference and the first network connection mode, so as to align the sending timing of the heartbeat packet with the opening timing of the receiving window, which is referred to as window alignment or phase alignment for short, so as to synchronize the receiving and sending timings of the heartbeat packet.

In the intelligent network, a superior node sends a heartbeat packet to a subordinate node. The upper and lower nodes of the interactive heartbeat packet are adjacent two-level nodes. For example, the upper node refers to a central node, and the lower node refers to a first-level node; for another example, the upper node refers to a first-level node, and the lower node refers to a second-level node. That is, the upper node is a sending end electronic device of the heartbeat packet, and the lower node is a receiving end electronic device of the heartbeat packet.

In the embodiment of the application, window alignment may be understood as that the receiving-end electronic device may receive the heartbeat packet sent by the sending-end electronic device when being in a window receiving state based on a clock difference between the receiving-end electronic device and the sending-end electronic device, so as to efficiently receive the heartbeat packet, reduce power consumption, and perform online detection quickly based on the heartbeat packet.

In some embodiments, the window alignment means that a difference between a timing when the receiving-end electronic device enters the receiving state and a timing when the sending-end electronic device sends the heartbeat packet is less than or equal to a first preset value. The receiving terminal electronic equipment enters a receiving state after a receiving window of the receiving terminal electronic equipment is opened, and can be used for receiving the heartbeat packet. Therefore, the receiving end electronic equipment can open the receiving window at the proper time when the sending end electronic equipment sends the heartbeat packet, so that communication resources are not wasted due to the fact that the receiving window is opened too early, and the condition that the heartbeat packet cannot be normally acquired due to the fact that the receiving window is opened too late is avoided, and therefore the receiving window can receive the heartbeat packet quickly and efficiently.

For example, the reception window enters the reception state earlier than the transmission timing of the heartbeat packet. For example, the receiving window is opened earlier than the sending timing of the heartbeat packet. Therefore, the receiving window is already in a receiving state when the heartbeat packet is sent, and the electronic equipment at the receiving end can receive the heartbeat packet more quickly and efficiently.

For another example, the receiving window enters a receiving state when the heartbeat packet is sent. For example, the receive window is opened when a heartbeat packet is sent. Therefore, when the heartbeat packet is sent, the receiving window is just opened and enters a receiving state, the receiving window is already in the receiving state when the heartbeat packet reaches the receiving end electronic equipment in consideration of transmission delay, and the receiving end electronic equipment can receive the heartbeat packet more quickly and efficiently.

For another example, the receive window enters the receive state before the heartbeat packet reaches the receiving electronic device. For example, the receiving-end electronic device may determine in advance the timing at which the heartbeat packet reaches the receiving-end electronic device according to the transmission timing of the heartbeat packet and the transmission delay obtained by pre-calculation, so as to open the receiving window in advance before the heartbeat packet arrives, so that the receiving window waits for receiving the heartbeat packet in a receiving state, and thus the heartbeat packet can be received quickly and efficiently.

For another example, when the heartbeat packet reaches the receiving-end electronic device, the receiving window is opened to enter a receiving state. For example, the receiving end electronic device may determine in advance a timing at which the heartbeat packet reaches the receiving end electronic device according to the transmission timing of the heartbeat packet and the transmission delay obtained by the pre-calculation, so that a receiving window is opened and a receiving state is entered when the heartbeat packet arrives, thereby being capable of receiving the heartbeat packet quickly and efficiently.

For the upper and lower nodes supporting the first network connection mode, after the windows are aligned, after a certain node subsequently sends a small number (e.g., 1 or 2) of heartbeat packets, the lower node of the node can quickly detect the heartbeat packets. That is to say, after the receiving and sending opportunities of the heartbeat packet are synchronized, the lower node can subsequently receive the heartbeat packet in the receiving window quickly, accurately and efficiently, so that the interaction times of the heartbeat packet in unit time can be reduced, the reliability of receiving the heartbeat packet is improved, the communication cost and power consumption are reduced, and quick, accurate and timely online detection among multiple devices is realized.

In addition, for an electronic device that only supports the second network connection mode, the upper and lower nodes may exchange heartbeat packets and heartbeat response messages based on the clock difference and the second network connection mode.

Therefore, the scheme can realize the rapid, accurate and timely online detection of each electronic device supporting the first network connection mode or the second network connection mode in the intelligent connection network.

The following describes an online detection method provided in the embodiment of the present application with reference to the drawings, taking a central node, a primary node, and a secondary node in the intelligent network shown in fig. 1A and fig. 2, where an air interface transmission mode of a heartbeat packet is broadcast, and a receiving window of the heartbeat packet is a scanning window. The method can comprise the following steps:

after the upper and lower relations of each node in the intelligent network are determined, referring to the timing diagram shown in fig. 3A, the large screen is used as the central node, and the heartbeat packet group starts to be broadcast to the mobile phone and the watch which are used as the first-level nodes at the time t1. The heartbeat packet group may include N (N is an integer greater than 1) heartbeat packets sequentially sent at preset intervals (e.g., 20ms, 30ms, etc.) within a preset period. In some embodiments, each heartbeat packet in the heartbeat packet group carries a respective sending timestamp, for example, the 1 st heartbeat packet carries a sending timestamp t1 of its own, and the X1 st heartbeat packet carries a sending timestamp tX1 of its own.

Referring to fig. 3A, after receiving the X1 (X1 is an integer greater than or equal to 1 and less than or equal to N) heartbeat packets at time tr1, the mobile phone serving as the primary node sends a heartbeat response message to the large screen.

In some embodiments, the heartbeat response message sent by the handset to the large screen includes tr1 and the sending timestamp tX1 of the X1 st heartbeat packet. In other embodiments, the heartbeat response message sent by the mobile phone to the large screen includes tr1 and the identifier of the X1 st heartbeat packet, and the large screen may determine the sending timestamp tX1 of the X1 st heartbeat packet according to the identifier of the X1 st heartbeat packet.

After the large screen receives the heartbeat response message sent by the mobile phone at the moment of tnow1, the transmission delay between the large screen and the mobile phone is calculated to be tdelay1= (tnow 1-tX 1)/2. According to the transmission delay, the clock difference between the mobile phone and the large screen is tC1= tr1-tX1-tdelay1. The large screen can send the clock difference to the mobile phone, so that window alignment is carried out between the mobile phone and the large screen according to the clock difference, and the receiving and sending time of the heartbeat packet is synchronized. For an exemplary interaction flow between the large screen and the mobile phone about clock difference, see fig. 3B.

In the scheme described in the above embodiment, the large-screen terminal calculates the clock difference between the mobile phone and the large screen and sends the clock difference to the mobile phone terminal. In other embodiments, the mobile phone end may also calculate the clock difference between the mobile phone end and the large screen by itself, and the device end for calculating the clock difference is not limited in the embodiments of the present application.

Where the clock difference is used to represent the difference between the local clocks of the two electronic devices. The electronic device may obtain the local clock based on its own operating system. For example, java of the android system uses interface system. The local clock may be a relative clock which may be different from the universal time displayed to the user by the terminal device. The local clock may be, for example, a time after the power-on or a time up to a certain reference time (for example, 1/1970). For example, the local clock of the large screen is the time after power-on, the local clock of the mobile phone is also the time after power-on, and the clock difference is 3658 × 10 ⁹ ns. For another example, the local clock of the large screen is the time after the mobile phone is turned on, and the local clock of the mobile phone is the time from 1 month to 1 day to the present day in 1970.

Similarly, referring to fig. 3A, after receiving the xth 2 (X2 is an integer greater than or equal to 1 and less than or equal to N) heartbeat packets at time tr2, the wristwatch as a primary node sends a heartbeat response message to the large screen and carries tr2 and a transmission timestamp tX2 of the xth 2 heartbeat packet. After the large screen receives a heartbeat response message sent by the watch at the moment of tnow2, the transmission delay tdelay2= (tnow 2-tX 2)/2 is calculated. The clock difference between the watch and the large screen is tC2= tr2-tX2-tdelay2.

If the first network connection mode is supported between the central node and the first-level node, the broadcasting time of the subsequent heartbeat packet and/or the opening time of the scanning window can be controlled between the central node and the first-level node according to the clock difference, so that the broadcasting time of the heartbeat packet is aligned with the opening time of the scanning window. Namely, the central node and the primary node are aligned with each other, so that the scanning window is in a receiving state when the heartbeat packet is broadcast, and the receiving and sending time of the heartbeat packet is synchronous. After the windows are aligned, the heartbeat packet broadcasted by the central node can be quickly and accurately received by the primary node in the scanning window, so that the interaction times of the heartbeat packet in unit time can be reduced, the communication cost and power consumption are reduced, the reliability of receiving the heartbeat packet is improved, and quick, accurate and timely online detection between equipment is realized.

For example, in the intelligent network shown in fig. 1A, a first network connection mode bluetooth BLE is supported between the large screen and the mobile phone, and the broadcasting time of the subsequent heartbeat packet and/or the opening time of the scanning window may be controlled between the large screen and the mobile phone according to the clock difference, so that the scanning window of the mobile phone is also in a receiving state when the heartbeat packet is broadcasted by the large screen. Therefore, the heartbeat packet of the large-screen broadcast can be quickly and accurately received in the scanning window subsequently by the mobile phone, so that the interaction times of the heartbeat packet in unit time can be reduced, the invalid broadcast and scanning duty ratio are reduced, the reliability of receiving the heartbeat packet is improved, the communication cost and the power consumption are reduced, and quick, accurate and timely online detection between equipment is realized.

Similarly, bluetooth BLE in the first network connection mode is supported between the large screen and the watch, and the broadcasting time of the subsequent heartbeat packet and/or the opening time of the scanning window can be controlled between the large screen and the watch according to the clock difference, so that the scanning window of the watch is also in a receiving state when the heartbeat packet is broadcasted on the large screen. Therefore, the watch can quickly and accurately receive the heartbeat packet of the large-screen broadcast in the scanning window, so that the interaction times of the heartbeat packet in unit time can be reduced, the invalid broadcast and scanning duty ratio are reduced, the reliability of receiving the heartbeat packet is improved, the communication cost and the power consumption are reduced, and the quick, accurate and timely online detection between equipment is realized.

In some embodiments, when the first network connection mode is bluetooth BLE, one broadcast message for sending heartbeat packets may be an unconnected broadcast ADV _ non _ IND message. According to the Bluetooth protocol, the broadcast message of the type does not need to be replied by a special response message, so that the bandwidth occupation of a response message packet can be reduced, the number of message interaction in the online detection process is reduced, the power consumption is saved, the interaction flow is simplified, and the online detection efficiency is improved.

In the embodiments of the present application, window alignment may adopt a plurality of different strategies to control the broadcast timing of subsequent heartbeat packets and/or the opening timing of the scanning window according to the clock difference.

For example, in the first strategy, window alignment is performed between the large screen and the mobile phone, and between the large screen and the watch, according to the 1 st heartbeat packet in the heartbeat packet group broadcasted at time t1. Referring to fig. 3A, according to a first preset period T1, the large screen periodically broadcasts a heartbeat packet group at a time T1+ m × T1 corresponding to the local clock, where m is a positive integer. The mobile phone controls to periodically open a scanning window to receive the heartbeat packet at the time T1+ m × T1+ tC1 corresponding to the local clock based on the clock difference. Therefore, the opportunity of broadcasting the heartbeat packet group on the large screen is consistent with the activation opportunity of the scanning window of the mobile phone, the scanning window of the mobile phone is just opened when the 1 st heartbeat packet in the heartbeat packet group is broadcasted on the large screen, and the scanning window of the mobile phone is already opened when the 1 st heartbeat packet in the heartbeat packet group reaches the mobile phone, so that the detection efficiency and the response speed of the heartbeat packet can be improved, the invalid broadcasting and scanning duty ratio can be reduced, and the quick, accurate and timely connection and online detection between the large screen and the mobile phone can be realized.

Similarly, the large screen periodically broadcasts the heartbeat packet group at the time T1+ m × T1 corresponding to the local clock according to the first preset period T1. The watch controls to periodically open a scanning window to receive the heartbeat packet at the time T1+ m × T1+ tC2 corresponding to the local clock based on the clock difference. For an exemplary comparison between the windows before and after alignment according to the first strategy, see fig. 4.

In this scheme, the 1 st heartbeat packet in the heartbeat packet group may be a target heartbeat packet (also referred to as a target message) corresponding to the mobile phone and the watch. Based on the scheme, the mobile phone and the watch can enter the receiving state when the large screen sends the heartbeat packet group (namely, the 1 st heartbeat packet in the heartbeat packet group is sent), namely, the mobile phone and the watch can enter the receiving state when the large screen sends the target heartbeat packet in the heartbeat packet group, so that the target heartbeat packet can be quickly received, and the online detection efficiency is improved.

Or, in this scheme, the X1 st heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the mobile phone, and based on this scheme, the mobile phone can enter a receiving state when the heartbeat packet group is sent on a large screen (i.e., the 1 st heartbeat packet in the heartbeat packet group is sent), and is in the receiving state when the target heartbeat packet is sent on the large screen, so that the target heartbeat packet can be quickly received, and the online detection efficiency is improved. In this scheme, the X2 heartbeat package in the heartbeat package group is the target heartbeat package that the wrist-watch corresponds, and based on this scheme, the wrist-watch can get into the receiving state when big screen transmission heartbeat package group, is in the receiving state when big screen transmission target heartbeat package to can receive target heartbeat package fast, improve on-line measuring efficiency.

Illustratively, the heartbeat packet group is broadcast for the first time by the large screen at 16. After window alignment is carried out based on clock difference, the large screen is respectively positioned at 16 parts, which correspond to a local clock, of the position 16, 10 and 16 \8230, and a heartbeat package group is broadcasted; the mobile phone respectively opens a scanning window to receive heartbeat packets at 16; the watch respectively scans at 18, 18.

For another example, the heartbeat packet group is broadcast by the large screen at the 30ns corresponding to the local clock for the first time (i.e., a plurality of heartbeat packets in one heartbeat packet group are broadcast sequentially at the 30ns according to a preset interval, such as 20 ms), T1 is 5 minutes, the clock difference between the mobile phone and the large screen is 30 minutes, and the clock difference between the watch and the large screen is 2 hours. After window alignment is carried out based on clock difference, the large screen starts broadcasting heartbeat packet groups respectively at the 5 th 30ns, the 10 th 30ns and the 15 th 30ns which correspond to the local clock; the method comprises the steps that a mobile phone opens a scanning window to receive heartbeat packages respectively at 35 th minute 30ns, 40 th minute 30ns and 45 th minute 30ns \8230correspondingto a local clock; the watch respectively opens a scanning window to receive heartbeat packets at 5 th 30ns, 10 th 30ns and 15 th 30ns (82303030) at the 2 nd hour corresponding to the local clock.

In addition, because the probability that the mobile phone receives the heartbeat packet broadcasted on the large screen again at the tX1 time corresponding to the X1 st heartbeat packet in the heartbeat packets for the first time is higher after receiving the heartbeat packet broadcasted on the large screen, when the windows are aligned, the mobile phone can adjust the scanning start time of the heartbeat packet to the time corresponding to the X1 st heartbeat packet. Therefore, the window alignment precision is higher, and the heartbeat packet sent in the broadcast window can be quickly and accurately received in the scanning window subsequently by the mobile phone, so that the interaction times of the heartbeat packet in unit time can be reduced, the reliability of receiving the heartbeat packet is improved, the communication cost and power consumption are reduced, and quick, accurate and timely online detection between equipment is realized.

Therefore, in the second strategy, the handset and the watch perform window alignment according to the X1 st heartbeat packet and the X2 nd heartbeat packet respectively corresponding to the handset and the watch. Specifically, the large screen periodically broadcasts the heartbeat packet group at the time T1+ m × T1 corresponding to the local clock according to a first preset period T1. The mobile phone adjusts the opening time of a subsequent heartbeat packet scanning window according to the sending time tX1 of the first received X1-th heartbeat packet so as to align the windows. The mobile phone controls the time at which the local clock corresponds to tX1+ m × T1+ tC1, that is, the time at which the X1 st heartbeat packet is broadcast on the large screen, based on the clock difference, and periodically opens the scanning window to receive the heartbeat packet.

Similarly, the large screen periodically broadcasts the heartbeat packet at the time T1+ m × T1 corresponding to the local clock according to the first preset period T1. The watch adjusts the opening time of a subsequent heartbeat packet scanning window according to the first received sending time tX2 of the X2 th heartbeat packet so as to align the windows. The watch controls the moment tX2+ m T1+ tC2 corresponding to the local clock, namely the moment of broadcasting the X2 th heartbeat packet by the large screen, and periodically opens the scanning window to receive the heartbeat packet based on the clock difference. For an exemplary comparison between the window alignment before and after the window alignment corresponding to the second strategy, see fig. 5.

In the scheme, the X1 st heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to the mobile phone, and the X2 nd heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to the watch. Based on the scheme, the mobile phone and the watch can be in a receiving state when the target heartbeat packet is sent on a large screen, so that the target heartbeat packet can be quickly received, and the online detection efficiency is improved.

Illustratively, the large screen broadcasts a heartbeat packet group (including a plurality of heartbeat packets broadcast sequentially at preset intervals) starting at 16 00 corresponding to the local clock for the first time, tX1 is 16: 02 T1 is 5 minutes, the clock difference between the mobile phone and the large screen is 30 minutes, and the clock difference between the watch and the large screen is 2 hours. After window alignment is carried out based on clock difference, the large screen is respectively positioned at 16 parts, which correspond to a local clock, of the station; the mobile phone respectively comprises 16; the watch respectively comprises the following components of 18.

In the first strategy or the second strategy, the large screen periodically broadcasts a heartbeat packet group at the time of T1+ m × T1, and the mobile phone and the watch respectively open a scanning window according to the corresponding time of self window alignment, so as to receive the heartbeat packet.

In addition, after the lower node of the large screen receives the Xi (i is a positive integer from 1 to N) heartbeat packet of the large screen broadcast for the first time, the probability that the Xi heartbeat packet in the heartbeat packet is received again in the follow-up process is high. Therefore, in the third strategy, the large screen can adjust the broadcast timing of the subsequent heartbeat packet group to the transmission time corresponding to the Xi-th heartbeat packet, that is, the large screen can adjust the broadcast timing of the subsequent heartbeat packet group according to tXi. When the large screen is provided with a plurality of subordinate nodes, the large screen can broadcast the heartbeat packet group to the subordinate nodes once without broadcasting the heartbeat packet group to each subordinate node once, so that the sending flow of the heartbeat packet is simplified, the number of message interaction is reduced, and the power consumption is saved. At this time, the large screen may adjust the broadcasting timing of the subsequent heartbeat packet group according to the timing (also referred to as tX 0) in tXi corresponding to each of the plurality of lower nodes, so that the heartbeat packets broadcasted on the large screen can be efficiently, quickly, and timely scanned after the windows of the plurality of lower nodes are aligned.

For example, the mobile phone receives an X1 st heartbeat packet from the heartbeat packets broadcasted on the large screen for the first time, and the watch receives an X2 nd heartbeat packet from the heartbeat packets broadcasted on the large screen for the first time. If the timing of the transmission time tX1 corresponding to the X1 th heartbeat packet is earlier, that is, X0 is X1 and tX0 is tX1, the heartbeat packet group is broadcast at the transmission time corresponding to the X1 th heartbeat packet periodically after the large screen. That is, the large screen periodically broadcasts heartbeat packet groups at time tX1+ m × T1. The mobile phone opens a scanning window to receive the heartbeat packet at the time of tX1+ m T1+ tC 1; the watch opens a scan window to receive heartbeat packets at time tX2+ m x T1+ tC 2. For an example, see fig. 6 for a comparison between the alignment of the windows corresponding to the third strategy and the alignment of the windows.

In the scheme, the 1 st (i.e., X1-X1+ 1) heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to the mobile phone, and the X2-X1+1 heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to the watch. Based on the scheme, the mobile phone and the watch can enter a receiving state when the heartbeat packet group (namely the 1 st heartbeat packet in the heartbeat packet group) is sent by a large screen, so that the target heartbeat packet can be quickly received, and the online detection efficiency is improved. For example, X1 is 2, X2 is 3, a heartbeat packet group is broadcast at a sending time corresponding to the 2 nd heartbeat packet periodically after a large screen is displayed, the 1 st (i.e., 2-2+ 1) heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to a mobile phone, and the 2 nd (i.e., 3-2+ 1) heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to a watch.

Or, if the timing of the transmission time tX2 corresponding to the X2 th heartbeat packet is earlier, that is, X0 is X2 and tX0 is tX2, the heartbeat packet group is broadcast at the transmission time corresponding to the X2 th heartbeat packet periodically after the large screen. That is, the large screen periodically broadcasts heartbeat packet groups at time tX2+ m × T1. The mobile phone opens a scanning window to receive the heartbeat packet at the time of tX2+ m T1+ tC 1; the watch opens a scan window to receive heartbeat packets at time tX2+ m x T1+ tC 2.

In the scheme, the 1 st (i.e., X1-X2+ 1) heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to the watch, and the X1-X2+1 st heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to the mobile phone. Based on the scheme, the mobile phone and the watch can enter a receiving state when the heartbeat packet group is sent by the large screen, so that the target heartbeat packet can be quickly received, and the online detection efficiency is improved.

Illustratively, the large screen broadcasts the heartbeat packet group for the first time at 16 00 corresponding to the local clock, tX1 is 16: 02, tX1 is more front than tX2, T1 is 5 minutes, the clock difference between the mobile phone and the large screen is 30 minutes, and the clock difference between the watch and the large screen is 2 hours. After window alignment based on clock difference and tX1, the large screen is respectively in the following 16; the method comprises the following steps that (1) the mobile phone opens a scanning window to receive a heartbeat packet at a position of 16; the watch respectively comprises the following components of 18.

In the second and third strategies, the opportunity of broadcasting the heartbeat packet on the large screen is inconsistent with the opportunity of opening the scanning window by the mobile phone, the opportunity of broadcasting the heartbeat packet on the large screen is inconsistent with the opportunity of opening the scanning window by the watch, but the difference between the broadcasting opportunity and the opening opportunity of the scanning window is smaller and is smaller than or equal to the first preset value, the situation also belongs to window alignment, and the mobile phone and the watch can also receive the heartbeat packet efficiently, quickly, accurately and timely so as to perform online detection.

In addition, if the central node has only one primary node and the primary node receives the xth heartbeat packet in the heartbeat packet group broadcasted by the central node at the time t1 for the first time, window alignment can be performed between the central node and the primary node according to the clock offset tC and the xth heartbeat packet. For example, the central node periodically broadcasts the heartbeat packet group at the time tX + m × T1 corresponding to the local clock according to a first preset period T1. And the primary node controls to periodically open a scanning window to receive the heartbeat packet at the time tX + m T1+ tC corresponding to the local clock based on the clock difference tC.

In the scheme, the 1 st heartbeat packet in the heartbeat packet group is a target heartbeat packet corresponding to the first-level node, and the first-level node can enter a receiving state when the central node sends the target heartbeat packet, so that the target heartbeat packet can be quickly received, and the online detection efficiency is improved.

In addition, if the scheme provided by the embodiment of the present application is not used between the first-level node and the central node for window alignment, as shown in fig. 7, the first-level node usually needs a plurality of scanning windows to receive the heartbeat packet sent by the large screen, the receiving efficiency of the heartbeat packet is poor, the number of times of sending the heartbeat packet is large, the number of times of scanning of the scanning windows is large, and the power consumption of the first-level node and the central node is large.

In the embodiment of the application, after the first-level node receives the heartbeat packet sent by the large screen for the first time, the heartbeat packet is sent to the second-level node so as to perform online detection on the second-level node. For example, in the intelligent network shown in fig. 1A, after receiving the heartbeat packet for the first time, the mobile phone of the first-level node sends the heartbeat packet to the earphone and the speaker of the second-level node.

If the first network connection mode is supported between the first-level node and the second-level node, the first-level node and the second-level node can align windows according to the clock difference, and the time when the subsequent first-level node broadcasts the heartbeat packet and/or the time when the second-level node opens the scanning window are controlled, so that the scanning window enters a receiving state when the first-level node broadcasts the heartbeat packet. After the windows are aligned, the secondary node can quickly and accurately receive the heartbeat packet broadcast by the primary node in the scanning window, so that the interaction times of the heartbeat packet in unit time can be reduced, the reliability of receiving the heartbeat packet is improved, the communication cost and power consumption are reduced, and quick, accurate and timely online detection between devices is realized.

For example, in the smart network shown in fig. 1A, a first network connection mode bluetooth BLE is supported between the handset and the headset. After the handset receives the heartbeat packet for the first time, referring to fig. 3A, the heartbeat packet group starts to be broadcast at time tA, so that the headset can receive the heartbeat packet in the heartbeat packet group. If the earphone receives the X3 th heartbeat packet and the clock difference between the earphone and the mobile phone is tC3, the window alignment may be performed between the earphone and the mobile phone by using the above strategy based on the clock difference tC 3. For example, when the first policy is adopted, the mobile phone periodically broadcasts the heartbeat packet group at time tA + m × T1 corresponding to the local clock according to the first preset period T1. The mobile phone periodically opens a scanning window at tA + m T1+ tC3 corresponding to the local clock based on the clock difference to receive the heartbeat packet. Therefore, the heartbeat packet broadcasting time of the mobile phone is consistent with the activation time of the earphone scanning window, when the heartbeat packet is broadcasted by the mobile phone, the scanning window of the earphone is also opened, the invalid broadcasting and scanning duty ratio can be reduced, the efficiency and the response speed of heartbeat packet detection are improved, and quick, accurate and timely connection and online detection between the mobile phone and the earphone are realized.

If the first-level node and the second-level node support a second network connection mode but not a first network connection mode, the first-level node can periodically send heartbeat packets to the second-level node based on the second network connection mode according to a first preset period T1, and the second-level node can periodically wake up to operate and respond in real time according to the clock difference and the first preset period T1. Therefore, the secondary node can be awakened to operate and respond to the heartbeat periodically, the heartbeat packet can be received and responded efficiently, accurately and timely, disordered heartbeat packets and repeated heartbeat responses are reduced, and the power consumption of the secondary node is saved.

Exemplarily, wi-Fi is supported between the mobile phone and the loudspeaker box, wherein the Wi-Fi belongs to the second network connection mode and does not support the first network connection mode. As shown in fig. 8, the mobile phone sends a heartbeat packet group to the sound box at time tA based on Wi-Fi connection, and carries a sending timestamp tA. And after the sound box receives the heartbeat packet at the time tr4, replying a response message to the mobile phone, and carrying a receiving timestamp tr4. After the mobile phone receives the response message sent by the sound box at the moment of tnow4, the transmission delay tdelay4= (tnow 4-tA)/2 is calculated. The clock difference between the mobile phone and the sound box is tC4= tr4-tA-tdelay4. The mobile phone can inform the sound box of the clock difference, so that the sound box is awakened periodically to receive the heartbeat packet according to the clock difference and the first preset period T1.

Subsequently, the mobile phone periodically sends heartbeat packet groups to the sound box from the kernel bottom layer protocol stack at time tA + m × T1 corresponding to the local clock based on Wi-Fi connection. The loudspeaker box is awakened to operate periodically at the time tA + m T1+ tC4 corresponding to the local clock, real-time response is carried out after the heartbeat packet is received through Wi-Fi connection, disordered heartbeat packets and repeated heartbeat response can be reduced, and window alignment is not needed to be carried out like a first network connection mode.

That is to say, in the intelligent connection network shown in fig. 1A, the bluetooth BLE in the first network connection mode is supported between the mobile phone as the primary node and the headset as the secondary node, and the window alignment may be performed based on the clock difference, and the heartbeat packets are periodically interacted after the window alignment, so as to perform the online detection of the electronic device. Wi-Fi in a second network connection mode is supported between the mobile phone serving as the primary node and the loudspeaker serving as the secondary node, the first network connection mode is not supported, and heartbeat packets can be periodically interacted on the basis of clock difference, so that online detection of the electronic equipment is performed.

The online detection method provided by the embodiment of the present application is described above by taking a central node, a primary node, and a secondary node as examples in the intelligent network shown in fig. 1A. When the intelligent network further includes nodes of other levels (e.g., a third-level node and a fourth-level node), the central node sends the heartbeat packet to the first-level node, the first-level node sends the heartbeat packet to the second-level node, the second-level node can also send the heartbeat packet to the third-level node, and the third-level node can also send the heartbeat packet to the fourth-level node, and so on, which is not described herein again. Therefore, the heartbeat packets are efficiently, quickly and accurately received between the adjacent upper and lower nodes (or called as directly connected upper and lower nodes) of the whole network, so that the receiving efficiency of the heartbeat packets can be improved, the receiving and sending times and duration of the heartbeat packets are reduced, the power consumption of the electronic equipment is reduced, quick, timely and accurate online detection of a plurality of electronic equipment in the network can be realized based on the heartbeat packets, and the quantity of the electronic equipment which can be accessed into the intelligent network can be increased.

Therefore, the scheme can sequentially transmit heartbeat packets between upper and lower nodes in the whole intelligent network (so called heartbeat synchronization in the whole intelligent network), reduce out-of-order heartbeat, perform uniform and ordered online detection on each electronic device in the intelligent network, and further can use the online electronic devices to quickly, directly and cooperatively execute services.

And when the intelligent network networking is carried out before the service request, the efficiency of networking heartbeat synchronization can be improved, so that the equipment state and the online and offline response in the intelligent network are more real-time and accurate. Moreover, the energy consumption of background networking can be reduced, so that the network is ordered, and the network stability under the condition of a large number of devices is improved.

It is understood that the intelligent network shown in fig. 1A is only an example, and the intelligent network may have different network topologies, and may further have more electronic devices (such as an intelligent lamp, an intelligent curtain, an intelligent remote controller, an electronic lock, etc.) and more complex network connection relationships. The intelligent network with various structures can adopt the method to interact the heartbeat package so as to carry out online detection.

In addition, in some embodiments of the present application, after a node enters a bright screen state, a service is usually executed, and thus the node is not sensitive to power consumption, and the scanning action does not greatly affect the power consumption of the node. Therefore, when the node opens the scanning window to align the windows, the duty ratio of the scanning window can be larger, so that the node can receive the heartbeat packet timely and quickly, and the missing of the heartbeat packet caused by larger interference is reduced. Conversely, when the node enters the screen-off state, the duty cycle of the scanning window can be smaller to save power consumption.

In some other embodiments of the present application, the device types of the nodes are different, and the duty cycles of the scanning windows may also be different. For example, if the node is not sensitive to power consumption, the duty ratio of the scanning window may be larger, so as to ensure that the heartbeat packet can be received timely and quickly, and reduce missed heartbeat packet reception caused by large interference. If the node is sensitive to power consumption, the duty cycle of the scanning window can be smaller to save power consumption.

In addition, in the embodiment of the present application, the duration of the node scanning window may be preset, where the duration is longer than the duration of one heartbeat packet, for example, the duration may be set to be 3 heartbeat packets, so that the heartbeat packets can be received in the scanning window as much as possible and the duration of the scanning window is short, thereby reducing the power consumption of the node.

In some embodiments of the present application, when a certain node executes a service, sending a heartbeat packet group according to a first preset period T1 may be suspended. The central node may also trigger an adjustment of the time to start sending the groups of heartbeat packets periodically. For example, when the central node executes the service, the transmission of the heartbeat packet group according to the first preset period T1 may be suspended. After the service is finished, the central node may trigger to periodically send the heartbeat packet group according to a first preset period T1 from a time instant tAdj. The central node may inform the primary node of the adjusted time tAdj, and the primary node adjusts the scanning window accordingly for window alignment. And the subsequent nodes transmit the adjusted time tAdj to the respective lower nodes in sequence.

In addition, in some embodiments, the central node may trigger recalculation of the clock difference according to a preset second preset period T2, and perform clock difference calibration between nodes at different levels. When the clock difference changes or the change of the clock difference is larger than or equal to a second preset value, the nodes in the intelligent connection network update the clock difference and perform window alignment based on the clock difference again. The second preset period T2 is greater than the first preset period T1. For example, the first preset period T1 may be 5 minutes, the second preset period may be 1 hour, the central node broadcasts the heartbeat packet group every 5 minutes, and the clock difference is triggered and updated every 1 hour.

In some embodiments, the clock difference between nodes in the intelligent network may change over time, and the second predetermined period T2 may be a predetermined empirical value related to a threshold value for the cumulative change of the clock difference. That is, after interval T2, the cumulative change in clock difference may have exceeded the threshold, and the central node may trigger a recalculation of the clock difference.

In other embodiments, if a node finds that the number of heartbeat packets separated between the heartbeat packet received this time and the heartbeat packet received for the first time is greater than or equal to a third preset value, the clock difference may have a large change, and thus the central node may be requested to trigger updating of the clock difference. For example, the third preset value is 3, the mobile phone receives the 2 nd heartbeat packet of the large screen broadcast for the first time, and if the mobile phone receives the 7 th heartbeat packet of the large screen broadcast this time and 7-2=5 is greater than the third preset value 3, the clock difference may have a large change, so that the mobile phone may request the large screen to trigger to recalculate the clock difference. Then, each node performs window alignment again based on the clock difference.

In other embodiments, if a node finds that the number of heartbeat packets separated between a heartbeat packet received this time and a heartbeat packet received for the first time is greater than or equal to a fourth preset value, the node may report the number to an upper node of the node, and the upper node of the node may request the central node to trigger the update clock difference. For example, the fourth preset value is 4, the headset receives the 3 rd heartbeat packet broadcasted by the mobile phone for the first time, and if the headset receives the 9 th heartbeat packet broadcasted by the mobile phone this time and 9-3=6 is greater than the fourth preset value 4, the clock difference may have a large change, so that the headset may report to the mobile phone, and the mobile phone may request a large screen to trigger to recalculate the clock difference. Then, each node performs window alignment again based on the clock difference.

In other embodiments, if a node finds that the number of heartbeat packets spaced between a heartbeat packet received this time and a heartbeat packet received for the first time by a lower node of the node is greater than or equal to a fifth preset value according to a received heartbeat response message, it may request the central node to trigger an update clock difference. For example, if the fifth preset value is 3, the mobile phone determines that the earphone receives the 8 th heartbeat packet broadcasted by the mobile phone this time, and if the earphone receives the 4 th heartbeat packet broadcasted by the mobile phone for the first time, 8-4=4 is greater than the fifth preset value 3, the clock difference may have a large change, and thus the mobile phone may request a large screen to trigger to recalculate the clock difference. If the node is a central node, the update clock difference is triggered directly in this case. Then, each node performs window alignment again based on the clock difference.

In addition, in the embodiment of the application, if a node is newly added in the intelligent network, each node re-determines the network topology relationship, and re-calculates the clock difference and performs window alignment, so that after the windows are aligned, the heartbeat packets are interacted to perform online detection. If a certain node in the intelligent connection network leaves, each node re-determines the network topology relationship, and re-calculates the clock difference and performs window alignment, so that the heartbeat packets are interacted after the windows are aligned to perform online detection. If the central node changes due to the fact that a node is newly added or a node leaves, the new central node triggers and recalculates the clock error and conducts window alignment, and therefore the heartbeat packets are interacted after the windows are aligned to conduct online detection.

In some embodiments, as described above, after networking is successful, each device in the intelligent network may determine that each electronic device is online. If the certain electronic equipment leaves when the heartbeat packet is detected on line, offline information of the electronic equipment can be notified to the central node or each electronic equipment in the intelligent network, so that the central node or each electronic equipment can know the online condition of each electronic equipment in a unified manner.

In the intelligent network, after a certain node receives a heartbeat packet sent by a superior node of the node for the first time, a heartbeat packet group is sent to a subordinate node of the node. Subsequently, the node periodically sends the heartbeat packet group to the lower node according to T1 according to the time of sending the heartbeat packet to the lower node for the first time. Therefore, normally, when the node subsequently sends the heartbeat packet group to the lower node according to T1, the node has already received the heartbeat packet from the upper node. If the subsequent node does not receive the heartbeat packet from the upper node when sending the heartbeat packet group to the lower node according to the period, the network reason, the clock difference change or the upper node leaves and the like may cause an abnormality, so that the heartbeat packet group can be sent to the lower node according to the normal period, and the abnormality recovery processing is triggered. For example, after the windows are aligned, the mobile phone determines that the frequency of the heartbeat packet is respectively in 18; if the mobile phone does not receive the heartbeat packet broadcast by the large screen at 18.

In the process of exception recovery processing, if the node receives a heartbeat packet from a superior node within a preset time length, clock difference calibration can be carried out according to the received heartbeat packet; if the intermediate node still does not receive the heartbeat packet from the upper node within the preset time length, whether the upper node leaves or not can be determined, whether the network topology relation needs to be determined again or not, whether the clock difference needs to be recalculated and other related abnormal processing or not can be determined.

In the above embodiments of the present application, window alignment is used for sending and receiving heartbeat packets, so as to perform online detection. In other embodiments, the clock difference may also be determined based on other messages except the heartbeat packet, and the window alignment may also be used for interacting other target information, but not for sending and receiving the heartbeat packet, so that other applications except online detection may be performed. Therefore, the electronic equipment can quickly and accurately receive the target information in the receiving window, so that the interaction times of the information in unit time can be reduced, the communication cost and the power consumption are reduced, the receiving reliability of the target information is improved, and the target information among a plurality of electronic equipment in the intelligent connection network can be received and transmitted more quickly, accurately and timely.

For example, the target information may include basic information of a certain electronic device in the smart network or a change in network capability information. By adopting the scheme provided by the embodiment of the application, other electronic equipment in the intelligent network can quickly and accurately receive the target information in the receiving window after the windows are aligned, so that the change of the basic information or the network capacity information of the electronic equipment and the like can be obtained, and the other electronic equipment can correspondingly adapt or carry out other related processing according to the changed basic information or the network capacity information and the like of the electronic equipment. The scheme can improve the reliability of receiving the target information, and improve the efficiency of synchronously acquiring the basic information or the network capacity information change of a certain electronic device by a plurality of electronic devices in the intelligent network, so that the target information can be more quickly, accurately and timely received and transmitted among the plurality of electronic devices in the intelligent network.

For example, the basic information of the electronic device may include at least one of: at least one of an identification (device ID) of the electronic device, a name (device name) of the electronic device, a type (device type) of the electronic device, a Network identification (Network ID), weight information of the electronic device, role information of the electronic device, and version information of the electronic device. The identification of the electronic equipment is used for uniquely identifying one electronic equipment; the name of the electronic equipment is the name of the electronic equipment defined by a user or the name of the electronic equipment defined by a factory; the type of the electronic device indicates which type the electronic device belongs to, for example, the type is: cell-phone, PC, dress, earphone, glasses, audio amplifier, car machine, wisdom screen or car machine etc.. The network identifier is a unique networking identifier allocated by the network to the electronic device after the electronic device accesses the network, and may be, for example, a Unique Device Identifier (UDID). The version information of the electronic device indicates a version number of a current system of the electronic device. The network capability information may be referred to above in relation to the description.

Illustratively, the other electronic devices in the intelligent network previously store the IP address of the electronic device 1 so as to be able to perform service data transmission with the electronic device 1, and the target information is that the IP address of the electronic device 1 is replaced. Other electronic devices in the intelligent network can efficiently and accurately receive the target information based on window alignment. After receiving the target information, the other electronic devices in the intelligent network may update the previously stored IP address of the electronic device 1.

Further illustratively, the previous network capability of the electronic device 1 does not support point-to-point (P2P) communication, and the target information is that the electronic device 1 supports P2P communication. Other electronic devices in the intelligent network can efficiently and accurately receive the target information based on window alignment. After receiving the target information, other electronic devices in the intelligent network may perform P2P communication with the electronic device 1.

Referring to fig. 9, the method may include:

901. one or more second electronic devices obtain respective corresponding first clock differences, where the first clock differences are differences between local clocks of the second electronic devices and local clocks of the first electronic devices.

For example, the first electronic device may be a large screen as shown in fig. 1A, the second electronic device may be a mobile phone as shown in fig. 1A, and the first clock difference may be a clock difference tC1 between the mobile phone and the large screen.

902. The first electronic device sends the corresponding one or more first target messages to one or more second electronic devices.

903. And one or more second electronic devices control the second electronic devices to receive the corresponding first target messages when the second electronic devices are in the window receiving state according to the corresponding first clock difference.

For example, the second electronic device may control, according to the first clock difference and any one of the first to third policies, a timing at which the first electronic device sends the first target message and/or a timing at which the second electronic device enters a receiving state, so as to control the second electronic device to receive the corresponding first target message when the second electronic device is in the window receiving state.

For example, one or more second electronic devices control the second electronic devices to enter a window receiving state when the first electronic device sends a corresponding first target message according to a corresponding first clock difference and a first preset period, so that the second electronic devices receive the corresponding first target message when the second electronic devices are in the window receiving state.
