Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

First, it should be understood that, in the current wireless ad hoc network scheme, communication links between different communication devices generally transmit communication data by wire, or wirelessly transmit communication data by Wi-Fi 2.4G or Wi-Fi 5G/6G, and communication data cannot be transmitted by two communication links at the same time, under this background, other application patents filed on the same day of the present application have elaborated networking methods of multi-link communication, and specifically utilize techniques such as VLAN aggregation, super-VLAN, and Sub-VLAN, to avoid technical defects such as communication loop generation or communication disturbance when implementing multi-link communication, so as to improve flexibility between different communication devices of the wireless ad hoc network, for example, referring to fig. 1, fig. 1 is a schematic diagram showing multi-link communication, a lower slave device simultaneously connects 2.4G and 5G of its upper device, if the lower slave device still maintains wired connection and bandwidth meets requirements, the WiFi connection may be broken, or the wired connection may also be maintained, and if the current direct slave device still maintains wired connection and bandwidth meets requirements, the stability of data transmission of the lower slave device is affected by one or more than that the lower slave device is not stable, and the throughput of the communication links is not stable.

In a first embodiment of the multilink communication data transmission method of the present application, referring to fig. 2, the multilink communication data transmission method includes:

step S10, if it is detected that a first communication quality between the communication equipment and a target communication equipment is better than a second communication quality of a multi-band initial link of the communication equipment, establishing a target communication link between the communication equipment and the target communication equipment, wherein the multi-band initial link is a communication link of the communication equipment and a superior device of the communication equipment under different communication bands after the wireless ad hoc networking is successful;

and step S20, transmitting communication data through the target communication link.

In this embodiment, it should be noted that a communication link is used for characterizing a physical channel between communication devices of a wireless ad hoc network, and specifically, the communication link may be a bidirectional communication link, and after the wireless ad hoc network is successfully configured, the communication link exists between the communication devices of the wireless ad hoc network to implement transmission of communication data, where the communication quality of the communication link is related to factors such as signal strength, adjacent-to-adjacent frequency interference, and hop count with a master device, and the higher the signal strength is, the smaller the adjacent-to-adjacent frequency interference is, the fewer hop count with the master device is, and the better the link quality is, where the wireless ad hoc network includes a master communication device and a slave communication device. In a specific embodiment, the master communication device may manage a plurality of slave communication devices, and the slave communication devices may be communication devices directly connected to the master communication device or communication devices indirectly connected to the master communication device by connecting the slave communication devices to form a multi-level networking.

Additionally, it should be noted that, after the wireless ad hoc network is successfully configured, the communication device of the wireless ad hoc network may acquire a signal strength (a first signal strength) between the communication device of the wireless ad hoc network and a target communication device by using a preset signal strength algorithm, where the target communication device is used to characterize the communication devices in the wireless ad hoc network except the communication device applying the multilink communication data transmission method, for example, referring to fig. 3, and fig. 3 is a schematic networking diagram illustrating the wireless ad hoc network, where the wireless ad hoc network is a two-hop ad hoc network, the communication device 1 is a master communication device, the communication device 2, the communication device 3, the communication device 4, the communication device 5, the communication device 6, and the communication device 7 are slave communication devices, and assuming that the communication device 3 is a communication device applying the multilink communication data transmission method, the communication device except the communication device 3 may serve as the target communication device.

Additionally, it should be noted that the multiband initial link is a communication link between the communication device and a superior device of the communication device in different communication frequency bands after the wireless ad hoc network is successfully networked, where the communication frequency band may specifically be 2.4GHz, 5GHz, 6GHz, and the like, in a networking process of the wireless ad hoc network, a communication link in different communication frequency bands may be established between the communication device and the superior device of the communication device, and a configuration synchronization process and a protocol specification based on a wireless ad hoc network protocol ensure communication data synchronization, so as to achieve networking success, and after the wireless ad hoc network is successfully networked, information is synchronously configured on a slave communication device through a master communication device of the wireless ad hoc network, where the configuration information may be a username and a password of the wireless ad hoc network, a selection of a communication channel, a maintenance parameter of network stability, and backhaul link information in different communication frequency bands, where the backhaul link information specifically includes a ssid (Service Identifier), a Service Set Identifier, a passback password, an encryption mode, and the like.

Additionally, it should be noted that after the wireless ad hoc networking succeeds, the master communication device serves as a communication medium for data transmission between the slave communication device and the server, so as to implement data interaction between the slave communication device and the server, for example, after the slave communication device transmits the communication data to be transmitted back to the master communication device in a primary backhaul or a multi-backhaul, the master communication device transmits the communication data to the slave communication device, and when the master communication device receives the communication data to be transmitted from the server, the master communication device transmits the communication data to the slave communication device in a primary backhaul or a multi-backhaul.

As an example, steps S10 to S20 include: according to a preset signal strength algorithm, calculating first signal strength between the communication equipment and target communication equipment in real time, acquiring second communication qualities of communication links of the communication equipment and superior equipment of the communication equipment under different communication frequency bands after wireless ad hoc networking is successfully performed in real time, comparing the first signal strength with the second communication qualities, and if the first communication qualities are superior to the second communication qualities, establishing a target communication link between the communication equipment and the target communication equipment, wherein the communication links under different communication frequency bands can be specifically downlink communication links under different communication frequency bands or uplink communication links under different communication frequency bands, the downlink communication links are communication links between the communication equipment and inferior equipment of the communication equipment, and the uplink communication links are communication links between the communication equipment and superior equipment of the communication equipment; communicating communication data over the target communication link.

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

step A10, determining a link disconnection order corresponding to the first frequency band initial link and the second frequency band initial link;

step A20, according to the link disconnection sequence, sequentially disconnecting the first frequency band initial link and the second frequency band initial link;

step a30, respectively establishing a target communication link that is the same as a first communication frequency band of the first frequency band initial link and a second communication frequency band of the second frequency band initial link.

In this embodiment, it should be noted that, after the first frequency band initial link and the second frequency band initial link are successfully configured in the wireless ad hoc network, the communication device and the superior device of the communication device communicate with each other in different communication frequency bands, for example, the first frequency band initial link may be a 2.4GHz frequency band communication link, and the second frequency band initial link may be a 5GHz frequency band communication link.

As an example, steps a10 to a30 include: comparing the link quality of the first frequency band initial link with the link quality of the second frequency band initial link to obtain a frequency band link quality sequence, and inverting the frequency band link quality sequence to obtain a link disconnection sequence corresponding to the first frequency band initial link and the second frequency band initial link in common, for example, in an implementable manner, if 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 sequence 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 sequence, firstly disconnecting the second frequency band initial link, and then disconnecting the first frequency band initial link; and respectively establishing a target communication link which is the same as a first communication frequency band of the first frequency band initial link and a second communication frequency band of the second frequency band initial link, wherein the first communication frequency band may be specifically 2.4GHz, and the second communication frequency band may be specifically 5GHz.

Wherein the step of determining a link disconnection order corresponding to the first frequency band initial link and the second frequency band initial link comprises:

step B10, acquiring a first link flow of the first frequency band initial link and a second link flow of the second frequency band initial link;

step B20, detecting whether the first link flow is superior to the second link flow;

step B30, if yes, taking a first preset disconnection order as the link disconnection order, where the first preset disconnection order is a link disconnection order of disconnecting the second frequency band initial link first and then disconnecting the first frequency band initial link;

and step B40, if not, taking a second preset disconnection sequence as the link disconnection sequence, wherein the second preset disconnection sequence is the link disconnection sequence of disconnecting the first frequency band initial link and then disconnecting the second frequency band initial link.

In this embodiment, it should be noted that, in the multi-link communication process, there is a difference in link traffic conditions of different communication links. In order to reflect the communication capacities of different communication links more objectively, the data transmission condition of the communication link can be queried, and then the link disconnection sequence of the first frequency band initial link and the second frequency band initial link is determined according to the data transmission condition, wherein the first link flow and the second link flow are both attached to the link flow, and the link flow is used for representing the data transmission condition of the communication link.

As an example, steps B10 to B40 include: acquiring first link flow of the first frequency band initial link and second link flow of the second frequency band initial link; detecting whether the first link traffic is greater than the second link traffic; if the first link flow is detected to be larger than the second link flow, taking a first preset disconnection sequence as the link disconnection sequence, wherein the first preset disconnection sequence is the link disconnection sequence of disconnecting the second frequency band initial link and then disconnecting the first frequency band initial link; and if the first link flow is detected to be smaller than or equal to the second link flow, taking a second preset disconnection order as the link disconnection order, wherein the second preset disconnection order is the link disconnection order of disconnecting the first frequency band initial link and then disconnecting the second frequency band initial link.

Wherein the step of sequentially disconnecting the first frequency band initial link and the second frequency band initial link according to the link disconnection order comprises:

step C10, after detecting that the first frequency band initial link is disconnected, determining whether the second frequency band initial link has first data to be transmitted; if so, disconnecting the second frequency band initial link after the first data to be transmitted is transmitted through the second frequency band initial link; if not, disconnecting the second frequency band initial link; or the like, or, alternatively,

step C20, after detecting that the second frequency band initial link is disconnected, determining whether the first frequency band initial link has second data to be transmitted; if so, disconnecting the first frequency band initial link after the second to-be-transmitted data is transmitted through the first frequency band initial link; and if not, disconnecting the initial link of the first frequency band.

In this embodiment, it should be noted that, for different communication devices, there is a difference in the transmission schedule of the communication data in the process of disconnecting the multiband initial link and establishing the target communication link. In order to ensure that the transmission of the communication data is not affected by the disconnection of the multiband initial link and the establishment of the target communication link, the data transmission condition of the communication link of a certain communication frequency band which is disconnected later can be detected, and the communication link is disconnected when the communication link of the communication frequency band is detected to have no data transmission.

As an example, steps C10 to C20 include: after the first frequency band initial link is detected to be disconnected, determining whether first data to be transmitted exists in the second frequency band initial link or not according to third link flow of the second frequency band initial link; if the third link flow of the second frequency band initial link is larger than zero, determining that first data to be transmitted exists in the second frequency band initial link, and disconnecting the second frequency band initial link after detecting that the first data to be transmitted is transmitted through the second frequency band initial link; if the third link flow of the second frequency band initial link is equal to zero, directly disconnecting the second frequency band initial link; or the like, or, alternatively,

after the second frequency band initial link is detected to be disconnected, determining whether second data to be transmitted exists in the first frequency band initial link or not according to the fourth link flow of the first frequency band initial link; if the fourth link flow of the first frequency band initial link is larger than zero, determining that second data to be transmitted exist in the first frequency band initial link, and disconnecting the first frequency band initial link after detecting that the second data to be transmitted is transmitted through the first frequency band initial link; and if the flow of the fourth link of the initial link of the first frequency band is equal to zero, directly disconnecting the initial link of the first frequency band.

Wherein, before the step of sequentially disconnecting the first frequency band initial link and the second frequency band initial link according to the link disconnection order, the multilink communication data transmission method further includes:

step D10, detecting whether a third data to be transmitted exists in the first frequency band initial link; if so, adjusting the communication transmission link of the third data to be transmitted to the second frequency band initial link; or the like, or, alternatively,

step D20, detecting whether the second frequency band initial link has fourth data to be transmitted; if so, adjusting the communication transmission link of the fourth data to be transmitted to the first frequency band initial link.

In this embodiment, it should be noted that, since both the first frequency band initial link and the second frequency band initial link can be used for transmitting communication data, in order to ensure normal transmission of communication data originally transmitted by a communication link depending on a certain communication frequency band after the communication link in the certain communication frequency band is disconnected, the communication link may be adjusted for the communication data.

As an example, steps D10 to D20 include: detecting whether a third data to be transmitted exists in the first frequency band initial link or not according to the fifth link flow of the first frequency band initial link; if the fifth link flow of the first frequency band initial link is larger than zero, determining that third data to be transmitted exists in the first frequency band initial link, and adjusting a communication transmission link of the third data to be transmitted to the second frequency band initial link; or the like, or, alternatively,

detecting whether fourth data to be transmitted exists in the second frequency band initial link or not according to the sixth link flow of the second frequency band initial link; if the flow of the sixth link of the second frequency band initial link is greater than zero, determining that fourth data to be transmitted exists in the second frequency band initial link, and adjusting a communication transmission link of the fourth data to be transmitted to the first frequency band initial link.

The first link flow, the second link flow, the third link flow, the fourth link flow, the fifth link flow and the sixth link flow are link flows of a multi-band initial link of the communication equipment at different time nodes.

Wherein the target communication link comprises a first target communication link and a second target communication link, and the step of transmitting communication data through the target communication link comprises:

step E10, acquiring a third communication quality of the first target communication link and a fourth communication quality of the second target communication link;

step E20, if the third communication quality is better than the fourth communication quality, transmitting communication data through the first target communication link;

and E30, if the fourth communication quality is better than or equal to the third communication quality, transmitting the communication data through the second target communication link.

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

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; and if the third signal strength is less than or equal to the fourth signal strength, transmitting communication data through the second target communication link.

The application provides a multilink communication data transmission method, which is applied to communication equipment of a wireless ad hoc network, namely, if detecting that first communication quality between the communication equipment and target communication equipment is superior to second communication quality of a multiband initial link of the communication equipment, establishing a target communication link between the communication equipment and the target communication equipment, wherein the multiband initial link is a communication link between the communication equipment and superior equipment of the communication equipment under different communication frequency bands after the wireless ad hoc network is successfully organized; communicating communication data over the target communication link. The communication quality can objectively reflect the bandwidth conditions of communication links under different communication frequency bands between the communication equipment and other communication equipment in the wireless ad hoc network, and further when the communication quality between the communication equipment and the target communication equipment is detected to be superior to the communication quality between the communication equipment and the superior equipment of the communication equipment after the networking of the wireless ad hoc network is successful, the target communication link between the communication equipment and the target communication equipment is directly established, and communication data is transmitted through the target communication link, so that the purpose of avoiding the limitation of the data throughput of the communication equipment by the communication link between the communication equipment and the superior equipment of the communication equipment can be realized. That is, the purpose of transmitting communication data through a communication link with higher signal strength is achieved. And when the communication device transmits the communication data, the communication data can be transmitted only through a communication link between the communication device and the directly connected superior device or subordinate device when the wireless ad hoc network is established. Therefore, the technical defects that the data throughput of the subordinate slave device is unstable when the subordinate slave device transmits and receives data to and from the directly connected superior device or subordinate device and further the internet experience of a user is poor due to the fact that the quality of a communication link is poor and the data throughput of the subordinate slave device is influenced by the communication link are overcome. Therefore, the stability of data transmission in the multilink communication process is improved.

Example two

Further, referring to fig. 4, in another embodiment of the present application, the same or similar contents as those in the first embodiment may refer to the above description, and are not repeated herein. On this basis, before the step of establishing the 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:

step F10, according to the second communication quality of the multi-band initial link, at least one candidate communication device corresponding to the communication device is inquired in the wireless ad hoc network;

step F20, obtaining a first communication quality between the communication device and each of the candidate communication devices, where each of the candidate communication devices includes a target communication device.

In this embodiment, it should be noted that, because the topology structure of the wireless ad hoc network is generally complex, if any communication device in the wireless ad hoc network except the communication device is taken as the target communication device, it will take a long time to compare the first communication quality and the second communication quality, so that the establishment efficiency of the target communication link is low, and further, based on the correspondence between the second communication quality in the current state and each communication device of the wireless ad hoc network, the acquisition range of the first communication quality is narrowed, that is, the calculation amount of the first communication quality and the comparison amount of different link qualities are reduced, where the candidate communication device is used to represent the communication device in the wireless ad hoc network whose scoring difference value with the second communication quality is within the preset difference threshold range.

As an example, steps F10 to F20 include: using the second communication quality of the multi-band initial link as an index, and inquiring at least one corresponding candidate communication device in a preset signal intensity table; a first communication quality between the communication device and each of the candidate communication devices is obtained, wherein each candidate communication device includes a target communication device.

The embodiment of the application provides a communication quality obtaining method. That is, according to the second communication quality of the multiband initial link, at least one candidate communication device corresponding to the communication device is inquired in the wireless ad hoc network; a first communication quality between the communication device and each of the candidate communication devices is obtained, wherein each candidate communication device includes a target communication device. Compared with the method that the first communication quality between the communication equipment and all target communication equipment in the wireless ad hoc network is directly calculated, the first communication quality and the second communication quality are respectively compared to establish a communication quality acquisition mode of a target communication link.
