[0045] Embodiments of this disclosure are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0046] In areas without mobile signal, it is not possible to flexibly and freely build a network. Even with devices such as Wi-Fi routers or power supplies, a centralized network still needs to be built. However, decentralized networks make network setup more convenient and faster.

[0047] In related technologies, Bluetooth networking methods include multi-hop communication, connecting multiple piconet networks via bridge nodes, or achieving one-to-many communication via broadcast channels. However, these methods cannot achieve low-power networking. While multi-hop communication can achieve decentralized networking, it requires constant maintenance of the communication link, resulting in high power consumption. Currently, there is no networking method that can achieve both decentralized networking and reduced power consumption.

[0048] Therefore, this disclosure provides a networking method that uses broadcasting to build a decentralized network, thereby ensuring that the network will not lose connection due to any node going offline. It also makes flexible use of multi-hop mechanisms to enable longer communication distances and wider coverage.

[0049] The networking method proposed in this disclosure can be applied to the field of Bluetooth technology, as well as the field of WIFI technology or other future communication technology fields.

[0050] The networking method and communication device provided in this application will be described in detail below with reference to the accompanying drawings.

[0051] Figure 1 This is a schematic diagram of a communication device according to an embodiment of the present disclosure, such as... Figure 1 As shown, the communication system 100 includes a first terminal device 101 and a second terminal device 102. The first terminal device 101 can share network access information with the second terminal device 102 through a first communication link established between the two devices. After sending the information, the first communication link is promptly disconnected, and the system switches to broadcast mode to exchange neighbor table information with the second terminal device. In response to receiving the neighbor table information broadcast by the second terminal device within a preset time period, the system completes the process of bringing the second terminal device into the network.

[0052] In some embodiments, the communication system further includes a third terminal device and a fourth terminal device.

[0053] In some embodiments, the first terminal device and the second terminal device are within the same visibility domain, therefore, a first communication link can be established between the first terminal device and the second terminal device. The third terminal device is not within the same visibility domain as the first terminal device, but is within the same visibility domain as the second terminal device. Therefore, the third terminal device can establish a communication link with the second terminal device, thereby joining the network based on the second terminal device's network access request.

[0054] Specifically, the third terminal device joins the network through the network access request of the second terminal device. After the third terminal device joins, the second terminal device needs to update its neighbor table and neighbor table information, and broadcast the updated neighbor table within a preset time period, so that the first terminal device can update its own neighbor table and neighbor table information based on the neighbor table broadcast by the second terminal device.

[0055] In some embodiments, the fourth terminal device may be a terminal device that is not in the network. The fourth terminal device is in the same visible domain as the first terminal device, but not in the same visible domain as the second and third terminal devices. Therefore, the first terminal device can receive the distress message broadcast by the fourth terminal device, and can forward the distress message to other terminal devices in the network through multi-hop forwarding.

[0056] In some embodiments, the first terminal device, the second terminal device, the third terminal device, and the fourth terminal device are mobile devices. That is, during the movement, the visibility between the devices will change due to the change in location. When the first terminal device moves out of the visible domain of the second terminal device, the first terminal device can obtain the neighbor table information of the second terminal device through forwarding from other terminal devices.

[0057] The following embodiments of this disclosure can be applied to, for example Figure 1 The communication system shown can also be applied to other communication systems, such as optical communication systems, satellite communication systems, and wired communication systems, and this disclosure does not limit such applications.

[0058] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0059] Figure 2 This is an interactive schematic diagram of a networking method proposed in an embodiment of this disclosure. Figure 2 As shown, it includes the following steps:

[0060] Step 201: The first terminal device creates a network and a first neighbor table, and performs a network scan.

[0061] In some embodiments, the first neighbor table includes a neighbor table identifier and a neighbor device identifier, and the information in the first neighbor table corresponds to the information in the first neighbor table.

[0062] In some embodiments, the first neighbor table information is obtained by extracting and compressing features from the first neighbor table.

[0063] In some embodiments, the neighbor table identifier reflects the number of neighboring devices in the neighbor table. For example, if the neighbor table identifier is 0, it means that there is only one device in the neighbor table, which is the device that created the neighbor table. If the neighbor table identifier is 2, it means that there are 3 devices in the neighbor table. The latter two devices are pulled into the network by the first device, or the second device is pulled into the network by the first device, and the third device is pulled into the network by the second device.

[0064] In some embodiments, the first terminal device can be any terminal device. The first terminal device is used to create a network and can pull any device within the visible domain into the network.

[0065] In some embodiments, the first terminal device may create a network by determining the identifier of the network and the encryption key for communication within the network.

[0066] In some embodiments, the creation of a first neighbor table by the first terminal device may involve constructing a neighbor map that includes the neighbor table identifier of the first terminal device and the neighbor information of the first terminal device.

[0067] In some embodiments, the information corresponding to the network created by the first terminal device is the relevant parameters shared when inviting other terminal devices to join the network.

[0068] In some embodiments, the first neighbor table created by the first terminal device is stored locally on the first terminal device. The information in the first neighbor table will increase as other devices join, but will not decrease as joined devices go offline.

[0069] In some embodiments, the first neighbor table is used by the first terminal device to determine other neighbor devices within the network, so as to identify devices that can communicate within the network.

[0070] In some embodiments, the first neighbor table reflects information about devices currently in the same network as the first terminal device, such as the device's neighbor table identifier, device ID, etc.

[0071] For example, when device AAAA creates a network, it creates a network ID, a device ID, and neighbor table information for the network devices.

[0072] In some embodiments, the first terminal device may perform network scanning by scanning for terminal devices capable of establishing communication links within its own visible domain. Due to the mobility of terminal devices, at different times, the first terminal device may scan for zero terminal devices or one or more terminal devices.

[0073] Step 202: The first terminal device determines the second terminal device.

[0074] In some embodiments, the first terminal device determines the second terminal device among the multiple terminal devices based on attribute information broadcast by the multiple terminal devices.

[0075] In some embodiments, the second terminal device is at least one of a plurality of terminal devices, and the attribute information indicates that the second terminal device supports networking.

[0076] In some embodiments, during the network scanning process of the first terminal device, at least one terminal device will broadcast, so that the first terminal device can determine the second terminal device based on the content of the broadcast received from at least one terminal device.

[0077] In some embodiments, the second terminal device may broadcast once every 80ms. Specifically, the broadcast frequency can be customized according to the scenario or requirements, and this disclosure does not limit it.

[0078] In some embodiments, the number of second terminal devices may be one or more, that is, the first terminal device identifies at least one second terminal device that supports networking among at least one terminal device.

[0079] In some embodiments, whether the second terminal device supports networking is an attribute information of the second terminal device, that is, the second terminal device informs the first terminal device that it supports networking through continuous broadcasting.

[0080] In some embodiments, the first terminal device determines the second terminal device based on attribute information broadcast by at least one terminal device, in response to an option triggered by the user.

[0081] For example, the device BBBB being pulled into the network first broadcasts EA, and after device AAAA in the network receives it, the user triggers the "user pulls into network" operation.

[0082] Step 203: The first terminal device establishes a first communication link with the second terminal device.

[0083] In some embodiments, after the first terminal device determines the second terminal device among at least one terminal device, the first terminal device establishes a first communication link with the second terminal device.

[0084] In some embodiments, the first communication link may be a Bluetooth communication link or a WIFI communication link, etc., and this disclosure does not limit it.

[0085] Step 204: The first terminal device sends a network access request to the second terminal device.

[0086] In some embodiments, after establishing a first communication link with a second terminal device, the first terminal device needs to send a network access request to the second terminal device. The network access request is used to request the second terminal device to join the network.

[0087] In some embodiments, the network access request is triggered by the user of the first terminal device. That is, after the user selects the second terminal device on the display interface of the first terminal device, a first communication link is established, and a network access request is sent to the second terminal device through the first communication link.

[0088] In some embodiments, after receiving a network access request, the second terminal device sends feedback to the first terminal device to indicate whether it agrees to the network access request. If it agrees to the network access request, the first terminal device can continue to perform the subsequent operations of adding users to the network; otherwise, the process ends.

[0089] For example, device AAAA sends a request to BBBB to join the network via a BLE link. BBBB determines whether to agree or disagree. If it does not agree, it disconnects the BLE connection and ends the process. If it agrees, it sends back "agree to join the network" and then device AAAA sends the "network entry parameters".

[0090] Step 205: The second terminal device sends feedback information to the first terminal device.

[0091] In some embodiments, the second terminal device sends feedback information to the first terminal device based on the network access request, in order to agree to join the network.

[0092] In some embodiments, the feedback information may be "agree to join the network".

[0093] In some embodiments, the feedback information may be triggered by the user of the second terminal device. That is, after the first terminal device sends a network access request, the display interface of the second terminal device displays the network access request, and the user of the second terminal device clicks "agree" on the display interface to trigger the second terminal device to send feedback information to the first terminal device.

[0094] Step 206: The first terminal device sends network access information to the second terminal device.

[0095] In some embodiments, in response to receiving feedback information from the second terminal device regarding the network access request, the first terminal device sends network access information to the second terminal device via the first communication link.

[0096] In some embodiments, the network access information may be network information of the network, including network access parameters and network key. The network access parameters may be the identifier of the network, etc., and the network key is used for encrypted transmission when communicating within the network.

[0097] For example, if BBBB agrees to AAAA's network access request, it will send back "Agree to network access", and AAAA will send "Network access parameters and network key" to BBBB.

[0098] Step 207: The first terminal device disconnects the first communication link and broadcasts the first neighbor table information.

[0099] In some embodiments, in response to the completion of network access information transmission, the first communication link is disconnected and the first neighbor table information of the first terminal device is broadcast.

[0100] In some embodiments, after the first terminal device sends network access completion information to the second terminal device through the first communication link, it can promptly disconnect the first communication link and switch to broadcast mode to broadcast the first neighbor table information of the first terminal device. The first neighbor table information is used by the second terminal device to determine the terminal devices that have a neighbor relationship with the first terminal device.

[0101] In some embodiments, the information broadcast by the first terminal device may also include the identifier and technical parameters of the first terminal device, service information, etc.

[0102] For example, after the parameters and other data are transmitted, the BLE link is disconnected, and AAAA sends its own DevInfo. Table 1 shows the format of the DevInfo:

[0103] Table 1

[0104] Network ID Device ID Neighbor Table Information

[0105] The neighbor table information format is shown in Table 2:

[0106] Table 2

[0107]

[0108] In some embodiments, in response to the completion of network access information reception, the second terminal device disconnects the first communication link and broadcasts its second neighbor table information. The information broadcast by the second terminal device also includes the second terminal device's identifier, technical parameters, service information, etc.

[0109] For example, after the parameters are transmitted, the two disconnect the BLE link, BBBB starts broadcasting Beacon in ES, and BBBB sends its own DecInfo.

[0110] Step 208: Determine that the second terminal device has joined the network.

[0111] In some embodiments, the first terminal device determines that the second terminal device has joined the network in response to receiving the second neighbor table information of the second terminal device within a first preset time period.

[0112] In some embodiments, the second terminal device determines that it has joined the network in response to receiving the first neighbor table information of the first terminal device within a first preset time period.

[0113] In some embodiments, the first terminal device may continuously receive the second neighbor table information of the second terminal device within a first preset time period, and the second terminal device may continuously receive the first neighbor table information of the first terminal device within the first preset time period, thereby determining that the second terminal device has successfully joined the network based on the interaction of the neighbor table information between the two.

[0114] In some embodiments, the first preset duration can be the time period for determining whether network access is successful. The first preset duration can be customized according to the scenario or requirements. For example, the first preset duration is 3 seconds.

[0115] In some embodiments, if the first terminal device does not receive the second neighbor table information from the second terminal device within a first preset time period, the display interface of the first terminal device will not display anything and will not perform any subsequent operations, which means that the second terminal device has failed to join the network.

[0116] In some embodiments, if the first terminal device receives the second neighbor table information from the second terminal device within a first preset time period, the display interface of the first terminal device displays a message indicating successful network access, such as "Successfully added a user" or "√".

[0117] In some embodiments, if the second terminal device does not receive the first neighbor table information from the first terminal device within a first preset time period, the display interface of the second terminal device will not display anything; conversely, if the second terminal device receives the first neighbor table information from the first terminal device within the first preset time period, the display interface of the second terminal device will display a prompt message indicating successful network access, such as "Network access successful" or "√".

[0118] For example, BBBB sends its own DevInfo, and AAAA checks whether it receives it. If it does not receive it, the process may not continue. If it receives it, AAAA displays "Successfully recruited," and at the same time, AAAA sends its own DecInfo. After BBBB receives it, it displays "Successfully joined the network," thus completing the network entry.

[0119] Step 209: The first terminal device updates the first neighbor table and the first neighbor table information.

[0120] In some embodiments, the first terminal device updates the first neighbor table and the first neighbor table information based on the second neighbor table information of the second terminal device.

[0121] In some embodiments, updating the first neighbor table may involve writing the device identifier of the second terminal device into the first neighbor table and simultaneously changing the identifier of the first neighbor table; updating the first neighbor table information involves updating the identifier of the first neighbor table and writing it into the second neighbor table information of the second terminal device. In other words, the updated first neighbor table information includes the neighbor table information of the first terminal device and the neighbor table information of the second terminal device.

[0122] In some embodiments, the second terminal device may also update its own neighbor table and neighbor table information based on the first neighbor table information of the first terminal device.

[0123] For example, when AAAA creates a network, it creates mapA, which is stored on device AAAA. The ID of this map is 0. The format is shown in Table 3, which represents the initial mapA for device AAAA:

[0124] Table 3

[0125]

[0126] Before BBBB joins the network, a mapB is also created and stored on the device BBBB. The ID of this mapB is 0. The format is shown in Table 4, which represents the initial mapB of the device BBBB:

[0127] Table 4

[0128]

[0129] After BBBB successfully joins the network, if it continuously receives EA Beacon messages from AAAA for 3 seconds, BBBB will update its neighbor table ID and neighbor table. Table 5 shows the mapB of BBBB after successful network joining.

[0130] Table 5

[0131]

[0132] After the update is complete, the neighbor table in the EA Beacon of device BBBB will be updated, and the new map will be broadcast for 3 seconds after the update.

[0133] Once BBBB successfully joins the network, if AAAA receives BBBB's EA Beacon information for 3 consecutive seconds, it will also consider BBBB to have successfully joined the network and will update its neighbor table ID and neighbor table. As shown in Table 6, this is the mapA of device AAAA.

[0134] Table 6

[0135]

[0136] Step 210: The first terminal device broadcasts the updated first neighbor table within a second preset time period.

[0137] In some embodiments, after updating the neighbor table and neighbor table information, the first terminal device will broadcast the updated first neighbor table within a second preset time period, and the first neighbor table information will continue to be broadcast at the original broadcast frequency.

[0138] In some embodiments, the second preset duration can be the broadcast duration of the updated neighbor table. The second preset duration can be customized according to the scenario or requirements, for example, set to 3 seconds.

[0139] In some embodiments, after updating the neighbor table and neighbor table information, the second terminal device will also broadcast the updated neighbor table within a second preset time period, and the updated neighbor table information will continue to be broadcast at the original broadcast frequency.

[0140] In some embodiments, the first terminal device broadcasts the updated first neighbor table within a second preset time period, which is used to enable other terminal devices in the network to update their own neighbor tables and neighbor table information according to the broadcast neighbor table, so that all terminal devices in the network can grasp the entire network topology.

[0141] In some embodiments, the updated neighbor table may be broadcast in the form of a compressed package, thereby reducing the resource consumption of data transmission.

[0142] In summary, the networking method proposed in this disclosure sends network access information to other terminal devices within the visible domain through a first communication link, and immediately disconnects after completing the network access negotiation, switching to exchanging neighbor table information via broadcast. Upon receiving neighbor table information from other terminal devices, it determines whether the other terminal devices have joined the network. This bidirectional neighbor table information exchange achieves network topology awareness, optimizes routing efficiency, and reduces flooding overhead. It also improves networking flexibility, enables decentralized networking, reduces link maintenance burden, enhances the determinism of the networking process, and ensures normal communication between devices within the network.

[0143] Figure 3 This is a flowchart illustrating the networking method executed by the first terminal device according to an embodiment of this disclosure. Based on Figure 2 The illustrated embodiments, such as Figure 3 As shown, the method also includes the following steps.

[0144] Step 301: In response to receiving the second neighbor table broadcast by the second terminal device, determine the third neighbor table information and the third neighbor table.

[0145] In some embodiments, the second neighbor table includes the device identifier of the third terminal device, and the third terminal device joins the network based on the network access request of the second terminal device.

[0146] In some embodiments, the method by which a third terminal device joins the network can be referred to Figure 2 The specific implementation of the illustrated embodiment is as follows: the second terminal device sends network entry information to the third terminal device through a communication link established with the third terminal device. After the network entry information is sent, the communication link is disconnected, and the neighbor table information of the second terminal device is broadcast. In response to receiving the neighbor table information of the third terminal device within a first preset time period, it is determined that the third terminal device has joined the network. Then, the neighbor table and neighbor table information of the second terminal device are updated to obtain the second neighbor table.

[0147] In some embodiments, after the second terminal device updates the neighbor table and neighbor table information, it broadcasts the second neighbor table within a second preset time period. After receiving the second neighbor table, the first terminal device updates its current neighbor table and neighbor table information according to the second neighbor table, and determines the third neighbor table and third neighbor table information.

[0148] For example, the network entry process between BBBB and CCCC is as described above. After receiving CCCC's EA Beacon for 3 consecutive seconds, BBBB assumes that CCCC has also successfully entered the network. BBBB then updates its neighbor table (mapID) and neighbor table, obtaining the device BBBB's mapB as shown in Table 7.

[0149] Table 7

[0150]

[0151] If AAAA discovers a new neighbor table map ID in BBBB's EA Beacon, it will update its own neighbor table based on the new map ID. The updated mapA of AAAA is shown in Table 8.

[0152] Table 8

[0153]

[0154] Step 302: Broadcast the information in the third neighbor table and broadcast the third neighbor table within the second preset time period.

[0155] In some embodiments, after updating the neighbor table and neighbor table information according to the neighbor table updated by the second terminal device, the first terminal device will broadcast the third neighbor table information and broadcast the third neighbor table within a second preset time period, so that other terminal devices in the network can update their own neighbor tables and neighbor table information according to the broadcast of the first terminal device.

[0156] For example, newly joined devices will jump between devices through the device neighbor table information, and each device will update its own neighbor table to know the latest status and topology of the network.

[0157] In the above embodiments, after a terminal device outside the network joins the network, it will inform other terminal devices in the network through the neighbor table, so that other terminal devices can update their own neighbor tables and neighbor table information. In this way, all terminal devices in the network can grasp the entire network topology and the latest status of the network, which provides a foundation for subsequent communication within the network.

[0158] Figure 4 This is a flowchart illustrating the networking method executed by the first terminal device according to an embodiment of this disclosure. Based on Figure 2 The illustrated embodiments, such as Figure 4 As shown, the method also includes the following steps.

[0159] Step 401: Receive the fourth neighbor table information broadcast by the second terminal device.

[0160] In some embodiments, the neighbor table identifier indicated by the fourth neighbor table information is greater than the neighbor table identifier indicated by the second neighbor table information.

[0161] In some embodiments, after inviting the third terminal device to join the network, the second terminal device will update its own neighbor table and neighbor table information, and determine the fourth neighbor table information and the second neighbor table corresponding to the fourth neighbor table information.

[0162] In some embodiments, the second terminal device broadcasts fourth neighbor table information within a second preset time period. However, due to the mobility of the terminal device, the first terminal device fails to receive the second neighbor table broadcast by the second terminal device. But after a period of time, due to the mobility of the terminal device, the first terminal device is able to receive the broadcast from the second terminal device, that is, it receives the fourth neighbor table information.

[0163] For example, if BBBB updates its neighbor table map after joining the CCCC network and sends it continuously for 3 seconds, but AAAA does not receive BBBB's latest neighbor table, then AAAA can determine whether BBBB has updated its neighbor table map from BBBB's neighbor table map ID.

[0164] Step 402: Send request information to the second terminal device.

[0165] In some embodiments, the request information is used to request the second terminal device to send the second neighbor table corresponding to the fourth neighbor table information.

[0166] In some embodiments, the first terminal device determines the neighbor table identifier based on the neighbor table identifier in the fourth neighbor table information. If the neighbor table identifier in the fourth neighbor table information is greater than the neighbor table identifier of the second terminal device stored by the first terminal device, it means that the second terminal device has updated the neighbor table, and the first terminal device needs to request the updated neighbor table from the second terminal device.

[0167] For example, if AAAA finds that the map ID sent by BBBB is greater than the ID of mapB stored locally by AAAA, it requests BBBB to send a new neighbor table map.

[0168] In some embodiments, the second terminal device rebroadcasts the second neighbor table based on the request information from the first terminal device.

[0169] In some embodiments, the duration for which the second terminal device rebroadcasts the second neighbor table can be a second preset duration or a third preset duration. The second preset duration and the third preset duration may not be the same. The second preset duration and the third preset duration can be customized according to the scenario or requirements, and this disclosure does not limit them.

[0170] For example, after receiving the request, BBBB adds its own neighbor table map to the EA Beacon again and continues to send it for 3 seconds.

[0171] Step 403: Based on the second neighbor table, determine the information of the third neighbor table and the third neighbor table.

[0172] In some embodiments, the first terminal device may update its own neighbor table and neighbor table information based on the second neighbor table rebroadcast by the second terminal device, that is, determine the third neighbor table and third neighbor table information.

[0173] For example, AAAA updates its neighbor table based on BBBB's new map, and the updated map of AAAA is shown in Table 8.

[0174] In the above embodiments, after other terminal devices join the network, the terminal device that initiated the invitation can broadcast to inform other terminal devices in the network that a device has joined, so that other terminal devices can update their neighbor tables and neighbor table information, enabling terminal devices in the network to grasp the entire network topology and the latest status, thus achieving flexible and convenient networking.

[0175] Figure 5This is a flowchart illustrating a networking method proposed in an embodiment of this disclosure. Based on Figures 2-4 The illustrated embodiments, such as Figure 5 As shown, it also includes the following steps:

[0176] Step 501: In response to the fact that no neighbor table information of the third terminal device is received within the second preset time period, the neighbor table information of the third terminal device is deleted from the third neighbor table information.

[0177] In some embodiments, the third terminal device can be any terminal device within the network.

[0178] In some embodiments, the neighbor table information of the third terminal device can be received by the first terminal device through multi-hop forwarding. If the neighbor table information of the third terminal device is not received within a second preset time period, it indicates that the third terminal device is offline, and the first terminal device needs to delete the neighbor table information of the third terminal device from the third neighbor table information.

[0179] In some embodiments, deleting the neighbor table information of the third terminal device from the third neighbor table information may be done by setting the bit position of the neighbor table information of the third terminal device in the third neighbor table information to zero.

[0180] For example, in the current network topology, devices AAAA, BBBB, and CCCC are all in the network. Each device sends an EA Beacon every 80ms. The EA Beacon carries the network ID, device ID, neighbor table information, etc. If device CCCC cannot continue to send broadcasts due to power depletion or shutdown, then if BBBB does not receive CCCC's EA Beacon for 3 consecutive seconds, it will assume that CCCC has left the network, update BBBB's EA Beacon neighbor table, and set the corresponding bit for CCCC to 0.

[0181] For example, such as Figure 7EThe diagram illustrates the correspondence between neighbor tables and their information. Map A is located locally on device AAAA, map B on device BBBB, and map C on device CCCC. The numbers 0x2, 0x0007, 0x0007, and 0x0007 below represent the neighbor table information sent by each device's EA Beacon. The preceding 0x2 represents the current device's neighbor table Map ID. For example, for device BBBB: the first 0x0007 can be converted to binary as 0b 0000 0000 0000 0111. The binary representation of 0x0007 has 32 bits. The last three 1s correspond to 0xBBBB, 0xAAAA, and 0xCCCC in map B. The neighbor table transmits the entire network topology information. For device BBBB, if device CCCC leaves the network, its map B information will not change; only the neighbor table information in its own EA Beacon will be modified. The neighbor table information for BBBB will be modified from 0x2,0x0007,0x0007,0x0007 to 0x2,0x0003,0x0003. For BBBB, the binary representation of 0x0003 is 0b 0000000000000011, where the 11 corresponds to the devices 0xBBBB and 0xAAA with IDs of 2mapB.

[0182] In the above embodiments, the offline status of any terminal device in the network will only change the neighbor table information of other devices, without causing changes to the neighbor table or interruption of communication within the network. Thus, the decentralized networking achieves flexibility and convenience, and improves the communication efficiency of the network.

[0183] Figure 6 This is a flowchart illustrating a networking method proposed in an embodiment of this disclosure. Based on Figures 2-5 The illustrated embodiments, such as Figure 6 As shown, it also includes the following steps:

[0184] Step 601: In response to receiving the distress message broadcast by the fourth terminal device, the distress message is sent to neighboring devices within the network through the network.

[0185] In some embodiments, the fourth terminal device is not within the network.

[0186] In some embodiments, the fourth terminal device may be a device that is in the same visible domain as the first terminal device but has not joined the network.

[0187] In some embodiments, after an emergency occurs, the fourth terminal device activates an emergency distress mode and sends distress information via broadcast. The frequency of the broadcast by the fourth terminal device can be defined by the user of the fourth terminal device.

[0188] In some embodiments, the distress message broadcast by the fourth terminal device may include the location information of the fourth terminal device, as well as information such as the device identifier and technical parameters of the fourth terminal device. The location information may be latitude and longitude information, GNSS positioning information, etc., and this disclosure does not limit this.

[0189] In some embodiments, the first terminal device can receive the distress message broadcast by the fourth terminal device, and then forward the distress message to neighboring devices in the network through multi-hop forwarding via the network.

[0190] In some embodiments, neighboring devices within the network can be all devices in the current neighbor table of the first terminal device.

[0191] For example, in the event of an emergency, such as an earthquake or someone getting lost outdoors, the emergency distress mode can be activated. The device periodically sends location information via EA Beacon, allowing rescuers to easily locate the person using their mobile phones.

[0192] The message format in emergency mode is shown in Table 9:

[0193] Table 9

[0194] SOS Device Location Information (Lat / Long / GNSS Positioning Information)

[0195] In the above embodiments, through a decentralized network, in the event of an emergency, any device that communicates with a device outside the network can notify other devices within the network through multi-hop forwarding, thereby improving the efficiency of rescue in emergency situations.

[0196] In summary, the networking method proposed in this disclosure sends network access information to other terminal devices within the visible domain through a first communication link, and immediately disconnects after completing the network access negotiation, switching to exchanging neighbor table information via broadcast. Upon receiving neighbor table information from other terminal devices, it determines whether the other terminal devices have joined the network. This bidirectional neighbor table information exchange achieves network topology awareness, optimizes routing efficiency, and reduces flooding overhead. It also improves networking flexibility, enables decentralized networking, reduces link maintenance burden, enhances the determinism of the networking process, and ensures normal communication between devices within the network.

[0197] The following is a specific implementation method for a networking approach, using a Bluetooth-based networking method as an example:

[0198] Figure 7A A network topology diagram of the networking method, such as Figure 7A As shown, ID1_1, ID1_2, ID1_3, ID2_1, and ID2_2 are in one visible domain; ID2_1, ID2_2, ID2_3, ID2_4, and ID3_1 are in another visible domain; and ID3_1, ID4_1, ID4_2, and ID4_3 are in yet another visible domain. All these network nodes collectively form a network without a central node. All network nodes have equal power, and each node must store all network information: network name, the entire network's neighbor table, and the names of all network nodes.

[0199] Figure 7B Here is a flowchart of the network access process. The network access process is as follows:

[0200] 1. Create a network

[0201] The process of creating a network begins with sending a BLE EA broadcast. EA broadcasts are sent every 80ms and contain the network ID, device ID, and neighbor table information for the network devices. Except for the network ID, all other information in the EA broadcast needs to be encrypted.

[0202] The content of EA broadcasts is shown in Table 1:

[0203] Table 1

[0204] Network ID Device ID Neighbor Table Information

[0205] The format of the neighbor table information is shown in Table 2 below:

[0206] Table 2

[0207]

[0208] 2. Recruiting people to join the network

[0209] Broadcast and connection initiation:

[0210] The device BBBB being pulled into the network first broadcasts to EA. After receiving the broadcast, device AAAA in the network triggers the "user pulls into network" operation, and then the two establish a BLE link (Connect BLE Link).

[0211] Network access request and response: AAAA sends a "request to join the network" to BBBB via the BLE link. BBBB determines whether to agree. If it does not agree, it disconnects the BLE connection and ends the process. If it agrees, it sends back "agree to join the network". AAAA then sends "network access parameters and network key" to BBBB.

[0212] Link Disconnection and Subsequent Broadcast: After completing the transmission of parameters, the two disconnect the BLE link (Disconnect BLELink), and BBBB starts broadcasting the EA Beacon.

[0213] Network access confirmation: BBBB sends its own DevInfo, and AAAA checks whether it has received it. If it has not received it, the process may not continue. If it has received it, AAAA displays "Successful recruitment", and at the same time, AAAA sends its own DevInfo, and BBBB displays "Successful network access", thus completing the network access (i.e., confirming successful network access through DevInfo interaction).

[0214] 3. Neighbor table information update

[0215] When AAAA creates a network, it creates a network device mapA, which is stored on device AAAA. The ID of this map is 0.

[0216] The map format is shown in Table 3, which is the initial map A for device AAAA:

[0217] Table 3

[0218]

[0219] Before BBBB joins the network, a local network device mapB is created and stored on device BBBB. The ID of this map is 0.

[0220] The map format is shown in Table 4, which represents the initial mapB for device BBBB:

[0221] Table 4

[0222]

[0223] After BBBB successfully joins the network, if it continuously receives EA Beacon messages from AAAA for 3 seconds, BBBB will update its neighbor table ID and neighbor table. Table 5 shows the mapB of BBBB after successful network joining.

[0224] Table 5

[0225]

[0226] After the update is complete, the neighbor table in the EA Beacon of device BBBB will be updated, and the new map will be broadcast for 3 seconds after the update.

[0227] Once BBBB successfully joins the network, if AAAA receives BBBB's EA Beacon information for 3 consecutive seconds, it will also consider BBBB to have successfully joined the network and will update its neighbor table ID and neighbor table. As shown in Table 6, this is the mapA of device AAAA.

[0228] Table 6

[0229]

[0230] After the update is complete, the neighbor table in the EA Beacon information of device AAAA will be updated, and the new map will be broadcast for 3 seconds after the update.

[0231] If AAAA and BBBB receive each other's neighbor table map in their EA Beacon, they will update the map of the other device saved in their own device. After saving, they will update the neighbor table information in their own EA Beacon.

[0232] like Figure 7C The diagram shows a network topology, with devices AAAA and BBBB currently in the network.

[0233] 4. If a device CCCC arrives, CCCC can only receive broadcasts from BBBB, not AAAA. If BBBB invites CCCC to join the network, it will become like this: Figure 7D A schematic diagram of another type of network is shown.

[0234] The network entry process between BBBB and CCCC is as described above. After receiving CCC C's EABeacon for 3 consecutive seconds, BBBB assumes that CCCC has also successfully entered the network. BBBB then updates its neighbor table (map ID) and neighbor table, obtaining the device BBBB's mapB as shown in Table 7.

[0235] Table 7

[0236]

[0237] If AAAA discovers a new neighbor table map ID in BBBB's EA Beacon, it will update its own neighbor table based on the new map ID. The updated mapA of AAAA is shown in Table 8.

[0238] Table 8

[0239]

[0240] Similarly, newly joined devices will jump between devices through the device neighbor table information, and each device will update its own neighbor table to know the latest status and topology of the network.

[0241] If BBBB updates its neighbor table map after joining the CCCC network and sends it continuously for 3 seconds, but AAAA does not receive BBBB's latest neighbor table, then AAAA can determine whether BBBB has updated its neighbor table map by looking at BBBB's neighbor table map ID. If it finds that the map ID sent by BBBB is greater than the ID of mapB stored locally by AAAA, it requests BBBB to send a new neighbor table map. After receiving the request, BBBB adds its own neighbor table map to the EA Beacon again and sends it continuously for 3 seconds.

[0242] 5. Equipment off-grid

[0243] In the current network topology, devices AAAA, BBBB, and CCCC are all connected to the network. Each device sends an EA Beacon every 80ms. The EA Beacon carries the network ID, device ID, neighbor table information, etc.

[0244] If the CCCC device is unable to continue broadcasting due to power depletion or shutdown, BBBB will assume that the CCCC device has left the network if it does not receive the CCCC's EA Beacon for 3 consecutive seconds. BBBB will then update its EA Beacon neighbor table and set the corresponding bit for CCCC to 0.

[0245] 6. The correspondence between the neighbor table map and the information in EA Beacon

[0246] like Figure 7E The diagram shows the correspondence between the neighbor table and the neighbor table information. MapA is located on device AAAA, mapB is located on device BBBB, and mapC is located on device CCCC.

[0247] The numbers 0x2, 0x0007, 0x0007, and 0x0007 below represent the neighbor table information sent by the EA Beacon for each device. The preceding 0x2 represents the current neighbor table Map ID for this device, while the following 0x0007, 0x0007, and 0x0007 have different meanings for different devices. Taking device AAAA as an example:

[0248] The first 0x0007 can be converted to binary as: 0b 0000 0000 0000 0111;

[0249] The binary representation of 0x0007 has 32 bits. The last three 1s correspond to 0xAAAA, 0xBBBB, and 0xCCCC in map A. The neighbor table sends the entire network topology information.

[0250] For BBBB devices, if the CCCC device leaves the network, its mapB information will not change; only the neighbor table information in its EA Beacon information will be modified. The BBBB's neighbor table information will be changed from 0x2,0x0007,0x0007,0x0007 to 0x2,0x0003,0x0003. For BBBB, the binary representation of 0x0003 is 0b 0000 0000 0000 0011, where the 11 corresponds to the devices 0xBBBB and 0xAAA with ID 2mapB.

[0251] 7. Emergency SOS Mode

[0252] In emergencies such as earthquakes or people getting lost outdoors, the emergency distress mode can be activated. The device periodically sends location information via EA Beacon, allowing rescuers to easily locate the person using their mobile phones.

[0253] The message format in emergency mode is shown in Table 9:

[0254] Table 9

[0255] SOS Device Location Information (Lat / Long / GNSS Positioning Information)

[0256] If other devices within the network receive an emergency distress message, they will automatically forward it.

[0257] In summary, the beneficial effects of the above scheme are as follows:

[0258] 1. It allows for flexible and convenient network setup;

[0259] 2. No central node device is required; all devices can perform forwarding.

[0260] Figure 8 This is a schematic diagram of the structure of a communication device according to an embodiment of this disclosure. Figure 8 As shown, it includes a transceiver module 810 and a processing module 820.

[0261] The transceiver module is used to: in response to receiving feedback information from the second terminal device regarding the network access request, send network access information to the second terminal device through the first communication link; in response to the completion of sending the network access information, disconnect the first communication link and broadcast the first neighbor table information of the first terminal device.

[0262] The processing module is used to: determine whether the second terminal device has joined the network in response to receiving the second neighbor table information of the second terminal device within a first preset time period.

The first neighbor table includes a neighbor table identifier and a neighbor device identifier, and the information in the first neighbor table corresponds to the information in the first neighbor table. Based on the attribute information broadcast by multiple terminal devices, a second terminal device is determined among the multiple terminal devices. The second terminal device is at least one of the multiple terminal devices, and the attribute information indicates that the second terminal device supports networking. The transceiver module is further configured to establish a first communication link with the second terminal device and send a network access request to the second terminal device through the first communication link.

[0267] In some embodiments, the processing module is further configured to delete the neighbor table information of the third terminal device from the third neighbor table information in response to the fact that no neighbor table information of the third terminal device is received within a second preset time period.

[0268] In some embodiments, the transceiver module is further configured to, in response to receiving a distress message broadcast by the fourth terminal device, send the distress message to neighboring devices within the network, where the fourth terminal device is not within the network.

[0269] In summary, the communication device proposed in this disclosure transmits network access information through a communication link by receiving feedback information from other terminal devices regarding their network access requests. After transmission is completed, the communication link is disconnected, and neighbor table information is retransmitted via broadcast. Upon receiving neighbor table information broadcast by other terminal devices, the device confirms that other terminal devices have joined the network, thereby improving the flexibility of network formation, realizing decentralized networking, and ensuring communication within the network.

[0270] Figure 9 This is a schematic diagram of the structure of a communication device according to an embodiment of this disclosure. Figure 9 As shown, it includes a transceiver module 910 and a processing module 920.

[0271] The transceiver module is used to: in response to a network access request sent by a first terminal device through a first communication link, send a network access feedback to the first terminal device; receive network access information from the first terminal device through the first communication link; in response to the completion of receiving the network access information, disconnect the first communication link and broadcast the second neighbor table information of the second terminal device; the processing module is used to determine to join the network in response to receiving the first neighbor table information broadcast by the first terminal device within a first preset time period.

[0273] In some embodiments, the processing module is further configured to respond to the third terminal device joining the network based on the network access request of the second terminal device, update the second neighbor table information and the second neighbor table corresponding to the second neighbor table information, and determine the third neighbor table information and the third neighbor table; the transceiver module is further configured to broadcast the third neighbor table information and broadcast the third neighbor table within a second preset time period.

[0274] In some embodiments, the transceiver module is further configured to send a third neighbor table to the first terminal device in response to a request from the first terminal device.

[0276] In some embodiments, the transceiver module is further configured to receive distress information from a fourth terminal device broadcast by a first terminal device through a network, wherein the fourth terminal device is not within the network.

[0277] In the above embodiments, other terminal devices can join the network through any terminal device's network access request, thereby improving the flexibility of the network, realizing decentralized networking, and ensuring communication within the network.
