Description

Technical Field

[0002] With the continuous development of wireless communication technology, wireless ad hoc networks have been widely used in many fields due to their maintenance-free, strong self-healing and decentralized characteristics. For any communication device in a wireless ad hoc network, it can serve as both a data transmitter and a data receiver. At present, in the data transmission process of multiple backhaul communication links, the lower-level slave device usually transmits communication data through one or more communication links between the directly connected upper device and the lower-level slave device. However, since the bandwidth of the communication link is in dynamic change and the data throughput of the lower-level slave device is affected by the communication link, the data throughput of the lower-level slave device is unstable when sending and receiving data to the directly connected upper device or the lower device, which in turn makes the user's Internet experience poor.

Because communication quality can objectively reflect the bandwidth of the communication link between the communication device and other communication devices in the wireless ad hoc network in different communication frequency bands, when it is detected that the communication quality between the communication device and the target communication device is better than the communication quality between the communication device and the communication device's parent device after the wireless ad hoc network is successfully established, the target communication link is directly established between the communication device and the target communication device, and communication data is transmitted through the target communication link. This can achieve the purpose of circumventing the communication link between the communication device and the communication device's parent device from limiting the data throughput of the communication device. In other words, the purpose of transmitting communication data through a communication link with higher communication quality is achieved. Instead of having to rely solely on the communication link between the communication device and the directly connected superior or subordinate device when the wireless ad hoc network is established, communication data transmission on a communication device is overcome. This overcomes the technical drawback that occurs when the quality of the current communication link deteriorates and the data throughput of the subordinate slave device is affected by the communication link, resulting in unstable data throughput when the subordinate slave device sends and receives data to the directly connected superior or subordinate device, which in turn leads to a poor user experience. This improves the stability of data transmission during multi-link communication. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0068] Example 1

[0069] First of all, it should be understood that in the current wireless ad hoc network scheme, the communication links between different communication devices usually transmit communication data through wired transmission, or transmit communication data wirelessly through Wi-Fi 2.4G or Wi-Fi 5G / 6G, and cannot transmit communication data through two communication links at the same time. In this context, other patent applications submitted on the same day of this application have detailed the networking method of multi-link communication, specifically utilizing VLAN aggregation, super-VLAN and Sub-VLAN technologies to avoid technical defects such as communication loop generation or communication disorder when implementing multi-link communication, so as to enhance the flexibility between different communication devices in the wireless ad hoc network. For example, referring to Figure 1 , Figure 1To illustrate a schematic diagram of multi-link communication, a lower-level slave device is simultaneously connected to the 2.4G and 5G networks of its upper-level device. If the lower-level slave device still maintains a wired connection and the bandwidth meets the requirements, it can either disconnect the WiFi connection or continue to maintain the wired connection. Currently, in multi-link communication, the lower-level slave device usually transmits communication data through one or more communication links between the directly connected upper-level device and the lower-level slave device. However, due to changes in the quality of the communication link and the data throughput of the lower-level slave device being affected by the communication link, the data throughput of the lower-level slave device is unstable when sending and receiving data to the directly connected upper-level device or the lower-level device, which in turn makes the user's Internet experience poor. Therefore, there is an urgent need for a method to improve the stability of data transmission during multi-link communication.

[0070] The embodiment of the present application provides a multi-link communication data transmission method, which is applied to a communication device of a wireless ad hoc network. In the first embodiment of the multi-link communication data transmission method of the present application, referring to Figure 2 , the multi-link communication data transmission method includes:

[0071] Step S10: If it is detected that the first communication quality between the communication device and the target communication device is better than the second communication quality of the multi-band initial link of the communication device, a target communication link is established between the communication device and the target communication device, wherein the multi-band initial link is a communication link between the communication device and the upper device of the communication device in different communication frequency bands after the wireless ad hoc network is successfully established;

[0072] Step S20: transmitting communication data via the target communication link.

[0073] In this embodiment, it should be noted that the communication link is used to characterize the physical channel between the communication devices of the wireless ad hoc network, and can be specifically a bidirectional communication link. When the wireless ad hoc network is successfully established, a communication link exists between the communication devices of the wireless ad hoc network to realize the transmission of communication data. The communication quality of the communication link is related to factors such as signal strength, co-channel interference and the number of hops with the master device. The higher the signal strength, the smaller the co-channel interference and the fewer the hops with the master device, the better the link quality. The wireless ad hoc network includes a master communication device and a slave communication device. The master communication device of the wireless ad hoc network is used to represent the communication device that manages the entire networking of the wireless ad hoc network, which can be specifically one. The slave communication device of the wireless ad hoc network is used to represent the communication device managed by the master communication device, which can be specifically one or more. In a specific implementation, the master communication device can manage multiple slave communication devices. The slave communication device can be a communication device directly connected to the master communication device, or a communication device indirectly connected to the master communication device by connecting the slave communication device to the master communication device, thereby forming a multi-level network. Therefore, the multi-link communication data transmission method can be applied to any communication device of the wireless ad hoc network, which can be specifically a master communication device or a slave communication device.

[0074] In addition, it should be noted that after the wireless ad hoc network is successfully established, the communication device of the wireless ad hoc network can collect the signal strength (first signal strength) between it and the target communication device through a preset signal strength algorithm, wherein the target communication device is used to characterize the communication device other than the communication device applying the multi-link communication data transmission method in the wireless ad hoc network, for example, referring to Figure 3 , Figure 3 The figure is a network diagram representing a wireless ad hoc network, wherein the wireless ad hoc network is a two-hop ad hoc network, communication device 1 is a master communication device, communication device 2, communication device 3, communication device 4, communication device 5, communication device 6 and communication device 7 are all slave communication devices, assuming that communication device 3 is a communication device applying a multi-link communication data transmission method, then communication devices other than communication device 3 can be used as the target communication device.

[0075] In addition, it should be noted that the multi-band initial link is a communication link between the communication device and the upper device of the communication device in different communication frequency bands after the wireless self-organizing network is successfully established, wherein the communication frequency band can specifically be 2.4GHz, 5GHz and 6GHz, etc. During the networking process of the wireless self-organizing network, communication links in different communication frequency bands will be established between the communication device and the upper device of the communication device, and the configuration synchronization process and protocol specifications based on the wireless self-organizing network protocol will ensure communication data synchronization to successfully network. After the wireless self-organizing network is successfully established, the master communication device of the wireless self-organizing network synchronizes configuration information with the slave communication device, wherein the configuration information can be the username and password of the wireless self-organizing network, the selection of the communication channel, the parameters for maintaining network stability and the backhaul link information of different communication frequency bands, wherein the backhaul link information specifically includes SSID (Service Set Identifier), the password and encryption method of the backhaul link, etc.

[0076] In addition, it should be noted that after the wireless self-organizing network is successfully established, the master communication device acts as a communication medium for data transmission between the slave communication device and the server to realize data interaction between the slave communication device and the server. For example, when the slave communication device returns the communication data to be transmitted to the master communication device in one level or multiple levels, the master communication device sends the communication data to the slave communication device. When the master communication device receives the communication data to be transmitted from the server, the master communication device returns it to the slave communication device in one level or multiple levels.

[0077] As an example, steps S10 to S20 include: calculating the first signal strength between the communication device and the target communication device in real time according to a preset signal strength algorithm, and collecting the second communication quality of the communication link between the communication device and the upper device of the communication device in different communication frequency bands after the wireless self-organizing network is successfully established in real time, comparing the first signal strength and the second communication quality, and if the first communication quality is better than the second communication quality, establishing a target communication link between the communication device and the target communication device, wherein the communication link in different communication frequency bands can specifically be a downlink communication link in different communication frequency bands or an uplink communication link in different communication frequency bands, the downlink communication link is the communication link between the communication device and the lower device of the communication device, and the uplink communication link is the communication link between the communication device and the upper device of the communication device; and transmitting communication data through the target communication link.

[0078] Wherein, the first frequency band initial link and the second frequency band initial link, the step of establishing the target communication link between the communication device and the target communication device includes:

[0079] Step A10: determining a link disconnection order corresponding to both the initial link of the first frequency band and the initial link of the second frequency band;

[0080] Step A20: disconnecting the initial link of the first frequency band and the initial link of the second frequency band in sequence according to the link disconnection order;

[0081] Step A30: establishing target communication links that are the same as the first communication frequency band of the initial link in the first frequency band and the same as the second communication frequency band of the initial link in the second frequency band.

[0082] In this embodiment, it should be noted that the first frequency band initial link and the second frequency band initial link are communication links between the communication device and the upper device of the communication device in different communication frequency bands after the wireless self-organizing network is successfully established. For example, the first frequency band initial link can be a 2.4GHz frequency band communication link, and the second frequency band initial link can be a 5GHz frequency band communication link. Since the multi-band initial link includes multiple communication links in different communication frequency bands, in order to ensure the mutual independence between different communication links and the uninterrupted transmission of communication data when the communication links in different communication frequency bands are disconnected, the communication links in different communication frequency bands are disconnected in sequence according to the link disconnection order. At the same time, when the communication link in each communication frequency band is disconnected, the target communication link in the corresponding frequency band is established.

[0083] As an example, steps A10 to A30 include: performing a link quality comparison on the first frequency band initial link and the second frequency band initial link to obtain a frequency band link quality order, inverting the frequency band link quality order to obtain a link disconnection order corresponding to the first frequency band initial link and the second frequency band initial link. For example, in an implementable manner, assuming that the link quality of the first frequency band initial link is better than the link quality of the second frequency band initial link, the link disconnection order may be to disconnect the second frequency band initial link first, and then disconnect the first frequency band initial link; according to the link disconnection order, disconnect the second frequency band initial link first, and then disconnect the first frequency band initial link; establish target communication links that are the same as the first communication frequency band of the first frequency band initial link and the second communication frequency band of the second frequency band initial link, respectively, wherein the first communication frequency band may be specifically 2.4 GHz, and the second communication frequency band may be specifically 5 GHz.

[0084] The step of determining a link disconnection order corresponding to both the first frequency band initial link and the second frequency band initial link includes:

[0085] Step B10: Acquire a first link flow of the initial link of the first frequency band and a second link flow of the initial link of the second frequency band;

[0086] Step B20, detecting whether the traffic of the first link is better than the traffic of the second link;

[0087] Step B30: If yes, use the first preset disconnection order as the link disconnection order, wherein the first preset disconnection order is a link disconnection order in which the initial link of the second frequency band is disconnected first and then the initial link of the first frequency band is disconnected;

[0088] Step B40: If not, the second preset disconnection order is used as the link disconnection order, wherein the second preset disconnection order is a link disconnection order of disconnecting the first frequency band initial link first and then disconnecting the second frequency band initial link.

[0089] In this embodiment, it should be noted that during multi-link communication, different communication links may have different link traffic conditions. To more objectively reflect the communication capabilities of different communication links, the data transmission conditions of the communication links can be queried, and the disconnection order of the first frequency band initial link and the second frequency band initial link can be determined based on the data transmission conditions. The first link traffic and the second link traffic are both considered link traffic, and the link traffic is used to characterize the data transmission conditions of the communication links.

[0090] As an example, steps B10 to B40 include: obtaining the first link traffic of the initial link of the first frequency band and the second link traffic of the initial link of the second frequency band; detecting whether the first link traffic is greater than the second link traffic; if it is detected that the first link traffic is greater than the second link traffic, using the first preset disconnection order as the link disconnection order, wherein the first preset disconnection order is a link disconnection order of first disconnecting the initial link of the second frequency band and then disconnecting the initial link of the first frequency band; if it is detected that the first link traffic is less than or equal to the second link traffic, using the second preset disconnection order as the link disconnection order, wherein the second preset disconnection order is a link disconnection order of first disconnecting the initial link of the first frequency band and then disconnecting the initial link of the second frequency band.

[0091] The step of disconnecting the first frequency band initial link and the second frequency band initial link in sequence according to the link disconnection order includes:

[0092] Step C10: After detecting that the first frequency band initial link is disconnected, determining whether there is first data to be transmitted on the second frequency band initial link; if so, disconnecting the second frequency band initial link after the first data to be transmitted is transmitted via the second frequency band initial link; if not, disconnecting the second frequency band initial link; or,

[0093] Step C20: After detecting that the second frequency band initial link is disconnected, determine whether there is second data to be transmitted in the first frequency band initial link; if so, disconnect the first frequency band initial link after the second data to be transmitted is transmitted through the first frequency band initial link; if not, disconnect the first frequency band initial link.

[0094] In this embodiment, it should be noted that different communication devices may experience different progress in communication data transmission during the process of disconnecting the initial multi-band link and establishing the target communication link. To ensure that communication data transmission is not affected by the disconnection of the initial multi-band link and the establishment of the target communication link, the data transmission status of a communication link in a later disconnected communication frequency band may be detected, and the communication link may be disconnected if no data transmission is detected in the communication link in that communication frequency band.

[0095] As an example, steps C10 to C20 include: after detecting that the initial link of the first frequency band is disconnected, determining whether the initial link of the second frequency band has first data to be transmitted based on the third link traffic of the initial link of the second frequency band; if the third link traffic of the initial link of the second frequency band is greater than zero, determining that the initial link of the second frequency band has first data to be transmitted, and after detecting that the first data to be transmitted is transmitted through the initial link of the second frequency band, disconnecting the initial link of the second frequency band; if the third link traffic of the initial link of the second frequency band is equal to zero, directly disconnecting the initial link of the second frequency band; or,

[0096] After detecting that the initial link of the second frequency band is disconnected, determining whether the initial link of the first frequency band has second data to be transmitted based on the fourth link traffic of the initial link of the first frequency band; if the fourth link traffic of the initial link of the first frequency band is greater than zero, determining that the initial link of the first frequency band has second data to be transmitted, and disconnecting the initial link of the first frequency band after detecting that the second data to be transmitted is completely transmitted through the initial link of the first frequency band; if the fourth link traffic of the initial link of the first frequency band is equal to zero, directly disconnecting the initial link of the first frequency band.

[0097] Before the step of disconnecting the first frequency band initial link and the second frequency band initial link in sequence according to the link disconnection order, the multi-link communication data transmission method further includes:

[0098] Step D10: Detect whether there is third data to be transmitted in the initial link of the first frequency band; if so, adjust the communication transmission link of the third data to be transmitted to the initial link of the second frequency band; or

[0099] Step D20: Detect whether there is fourth data to be transmitted in the initial link of the second frequency band; if so, adjust the communication transmission link of the fourth data to be transmitted to the initial link of the first frequency band.

[0100] In this embodiment, it should be noted that since both the initial link of the first frequency band and the initial link of the second frequency band can be used to transmit communication data, in order to ensure the normal transmission of communication data that originally relied on the communication link of a certain communication frequency band for transmission after the communication link of the communication frequency band is disconnected, the communication link can be adjusted for the above-mentioned communication data.

[0101] As an example, steps D10 to D20 include: detecting whether there is third data to be transmitted on the initial link of the first frequency band based on the fifth link traffic of the initial link of the first frequency band; if the fifth link traffic of the initial link of the first frequency band is greater than zero, determining that there is third data to be transmitted on the initial link of the first frequency band, and adjusting the communication transmission link of the third data to be transmitted to the initial link of the second frequency band; or,

[0102] According to the sixth link traffic of the initial link of the second frequency band, detect whether there is fourth data to be transmitted on the initial link of the second frequency band; if the sixth link traffic of the initial link of the second frequency band is greater than zero, determine that there is fourth data to be transmitted on the initial link of the second frequency band, and adjust the communication transmission link of the fourth data to be transmitted to the initial link of the first frequency band.

[0103] The first link traffic, the second link traffic, the third link traffic, the fourth link traffic, the fifth link traffic and the sixth link traffic are link traffic of the multi-band initial link of the communication device at different time nodes.

[0104] The target communication link includes a first target communication link and a second target communication link, and the step of transmitting communication data through the target communication link includes:

[0105] Step E10: Acquire a third communication quality of the first target communication link and a fourth communication quality of the second target communication link;

[0106] Step E20: if the third communication quality is better than the fourth communication quality, transmitting communication data through the first target communication link;

[0107] Step E30: If the fourth communication quality is better than or equal to the third communication quality, transmit communication data through the second target communication link.

[0108] In this embodiment, it should be noted that after the target communication links corresponding to different communication frequency bands are successfully established, in order to ensure the efficiency of communication data transmission, the signal strength of the target communication links in different communication frequency bands can be collected in real time, and then the communication link for transmitting communication data is selected according to the strength of the signal strength. The first target communication link and the second target communication link are both target communication links, wherein the first target communication link can be 2.4 GHz and the second target communication link can be 5 GHz.

[0109] As an example, steps E10 to E30 include: obtaining a third signal strength of the first target communication link and a fourth signal strength of the second target communication link; if the third signal strength is greater than the fourth signal strength, transmitting communication data through the first target communication link; if the third signal strength is less than or equal to the fourth signal strength, transmitting communication data through the second target communication link.

[0110] The present application provides a multi-link communication data transmission method, which is applied to a communication device in a wireless ad hoc network. Specifically, if it is detected that the first communication quality between the communication device and the target communication device is better than the second communication quality of the multi-band initial link of the communication device, a target communication link is established between the communication device and the target communication device, wherein the multi-band initial link is a communication link between the communication device and the communication device's parent device in different communication frequency bands after the wireless ad hoc network is successfully established; and communication data is transmitted through the target communication link. Because the communication quality can objectively reflect the bandwidth of the communication link between the communication device and other communication devices in the wireless ad hoc network in different communication frequency bands, when it is detected that the communication quality between the communication device and the target communication device is better than the communication quality between the communication device and the communication device's parent device after the wireless ad hoc network is successfully established, the target communication link is directly established between the communication device and the target communication device, and communication data is transmitted through the target communication link. This can achieve the purpose of circumventing the limitation of the communication device's data throughput by the communication link between the communication device and the communication device's parent device. In other words, the purpose of transmitting communication data through a communication link with higher signal strength is achieved. Instead of having to rely solely on the communication link between the communication device and the directly connected superior or subordinate device when establishing the wireless ad hoc network, communication data transmission on a communication device is overcome. This overcomes the technical drawback of unstable data throughput when sending and receiving data to and from a directly connected superior or subordinate device, which can result in a poor user experience due to deteriorating communication link quality and the data throughput of subordinate slave devices being affected by the communication link. This improves the stability of data transmission during multi-link communication.

[0111] Example 2

[0112] Further, refer to Figure 4 In another embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction and will not be described in detail. On this basis, before the step of establishing a target communication link between the communication device and the target communication device if it is detected that the first communication quality between the communication device and the target communication device is better than the second communication quality of the multi-band initial link of the communication device, the multi-link communication data transmission method further includes:

[0113] Step F10, querying at least one candidate communication device corresponding to the communication device in the wireless ad hoc network according to the second communication quality of the multi-band initial link;

[0114] Step F20: Acquire a first communication quality between the communication device and each candidate communication device, wherein each candidate communication device includes a target communication device.

[0115] In this embodiment, it should be noted that, since the topological structure of a wireless ad hoc network is usually more complex, if any communication device in the wireless ad hoc network except the communication device is used as the target communication device, it will take a long time to compare the first communication quality and the second communication quality, thereby making the establishment efficiency of the target communication link low. Based on the correspondence between the second communication quality in the current state and the communication devices in the previous wireless ad hoc network, the collection scope of the first communication quality can be narrowed, that is, the calculation amount of the first communication quality and the comparison amount of different link qualities are reduced, wherein the candidate communication device is used to characterize the communication device in the wireless ad hoc network whose difference in score with the second communication quality is within a preset difference threshold range.

[0116] As an example, steps F10 to F20 include: using the second communication quality of the multi-band initial link as an index, querying at least one corresponding candidate communication device in a preset signal strength table; obtaining the first communication quality between the communication device and each candidate communication device, wherein each candidate communication device includes a target communication device.

[0117] An embodiment of the present application provides a method for obtaining communication quality. That is, based on the second communication quality of the multi-band initial link, query at least one candidate communication device corresponding to the communication device in the wireless ad hoc network; obtain the first communication quality between the communication device and each candidate communication device, wherein each candidate communication device includes a target communication device. Compared with directly calculating the first communication quality between the communication device and all target communication devices in the wireless ad hoc network, and comparing each first communication quality with the second communication quality respectively to establish a communication quality acquisition method for the target communication link. The embodiment of the present application filters out the candidate communication devices through the second communication quality of the multi-band initial link, and only obtains the first communication quality between the communication device and each candidate communication device by calculation. Since the number of candidate communication devices is less than the number of target communication devices, the purpose of reducing the amount of calculation when obtaining the communication quality can be achieved, so it lays the foundation for improving the efficiency of establishing the target communication link.
