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 obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection 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 usually transmit communication data by wire, or wirelessly transmit communication data by Wi-Fi 2.4G or Wi-Fi 5G/6G, but communication data cannot be transmitted by two communication links at the same time, and in this context, other application patents filed on the same day of this application have already elaborated networking methods of multi-link communication, specifically using techniques such as VLAN aggregation, super-VLAN, and Sub-VLAN, etc., 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, and a subordinate slave device connects 2.4G and 5G of its superior device at the same time, at this time, if the subordinate slave device still maintains the wired connection and the bandwidth meets the requirement, the WiFi connection may be broken, and the wired connection may also be maintained, at present, during the multilink communication, the subordinate slave device usually transmits the communication data through one or more communication links between the superior device directly connected to the subordinate slave device and the subordinate device directly connected to the subordinate slave device, that is, during the transmission of the communication data, there are various options, for example, referring to fig. 2, fig. 2 is a schematic diagram showing the transmission of the communication data, where communication device a is the superior device of communication device B, communication device C is the subordinate device of communication device B, both communication device a and communication device B, and both communication device B and communication device C have a 2.4GHz band communication link and a 5GHz band communication link, assuming that communication device a needs to transmit the communication data to communication device C via communication device B, and the communication device B acquires the communication data through the 2.4GHz band communication link, then the communication data has a possibility of being transmitted to the communication device C through the 5GHz band communication link, and since the link bandwidths of the 2.4GHz band communication link and the 5GHz band communication link are different, loss of the communication data is likely to occur in the transmission process of the communication data, and further the received communication data is not complete communication data, so a method for improving data transmission accuracy in the link communication process is urgently needed at present.
In a first embodiment of the symmetric link data transmission method according to the present application, referring to fig. 3, the symmetric link data transmission method includes:
step S10, acquiring data to be transmitted, which is transmitted by first communication equipment through a first communication link, wherein the first communication link is a communication link between the target communication equipment and the first communication equipment;
step S20, matching a target communication link corresponding to the first communication link for the data to be transmitted, wherein the link bandwidths between the target communication link and the first communication link are the same;
and step S30, transmitting the data to be transmitted to second communication equipment through the target communication link.
In this embodiment, it should be noted that the communication link is used to characterize a physical channel between communication devices of the wireless ad hoc network, and may specifically be a unidirectional communication link or a bidirectional communication link, and after the wireless ad hoc network is successfully organized, a communication link exists between the communication devices of the wireless ad hoc network to implement transmission of communication data, where the wireless ad hoc network manages the communication devices of the entire network of the wireless ad hoc network through the master communication device, and specifically may be one communication device, and the other communication devices of the wireless ad hoc network except the master communication device are slave communication devices, that is, the slave communication devices are used to characterize the communication devices managed by the master communication device, and specifically may be one or more communication devices.
Additionally, it should be noted that after the wireless ad hoc network is successfully configured, the communication device may serve as a data sending end to send communication data to other communication devices of the wireless ad hoc network, and may also serve as a data receiving end to receive the communication device sent by other communication devices of the wireless ad hoc network, and may also serve as an intermediate transmission node to implement transmission of the communication data, where the first communication device is configured to represent a data sending end of data to be transmitted, specifically, an uplink communication device or a downlink communication device of the target communication device, and the second communication device is configured to represent a data receiving end of data to be transmitted, specifically, a downlink communication device or an uplink communication device of the target communication device, for example, referring to fig. 4, and fig. 4 are schematic diagrams illustrating a wireless ad hoc network, where the wireless ad hoc network is a two-hop ad hoc network, and it is assumed that the communication device 1 transmits communication data to the communication device 6 and the communication device 3 is the target communication device, an uplink communication device (the communication device 1) of the communication device 3 is the first communication device, and a downlink communication device (the communication device 6) of the communication device 3 is the second communication device.
Additionally, it should be noted that the first communication link is a communication link between the target communication device and the first communication device, where the first communication link specifically includes a wireless communication link and a wired communication link of different communication bands, and the communication band may specifically be 2.4GHz, 5GHz, and 6GHz, and in a networking process of a wireless ad hoc network, one or more communication links may be established between the communication devices of the wireless ad hoc network, and synchronization of communication data is guaranteed based on a configuration synchronization flow and a protocol specification of a wireless ad hoc network protocol, and after networking is completed, information is synchronously configured on a slave communication device by 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 of different communication bands, and the backhaul link information specifically includes a password ssid (Service Set Identifier), a Service Set Identifier, an encryption manner of the backhaul link, and the like.
Additionally, it should be noted that after the wireless ad hoc networking is successful, the target communication device may serve as a communication medium for data transmission between the first communication device and the second communication device, so as to implement data interaction between the first communication device and the second communication device. For example, after the first communication device transmits the communication data to be transmitted back to the target communication device in a primary or multi-level manner, the target communication device transmits the communication data to the second communication device through the target communication link. Referring to fig. 5, fig. 5 is a schematic link diagram illustrating a symmetric multilink of a wireless ad hoc Network, where a communication device D is a first communication device, a communication device E is a target communication device, a communication device F is a second communication device, and a wireless communication link a, a wireless communication link b, and a wired communication link c are present between the communication device E and the communication device F, where the wireless communication link a and the wireless communication link b have different communication frequency bands, the wireless communication link a is configured as a sub-vlan2.1 (Virtual Local Area Network 2.1) by a master communication device of the wireless ad hoc Network, the wireless communication link b is configured as a sub-vlan2.2 by a master communication device of the wireless ad hoc Network, the wired communication link c is configured as a sub-vlan2.3 by a master communication device of the wireless ad hoc Network, link bandwidths of the same Virtual lan are the same, and sub-vlan2.1 between the communication device D and the communication device E and sub-vlan2.1 between the communication device E and the sub-vlan 2.2.1.
As an example, steps S10 to S30 include: the method comprises the steps of periodically receiving data to be transmitted, transmitted by first communication equipment through a first communication link, wherein the data to be transmitted is communication data waiting to be transmitted to second communication equipment; matching a target communication link with the same link bandwidth as the first communication link for the data to be transmitted; and transmitting the data to be transmitted to second communication equipment through the target communication link.
The step of matching the target communication link corresponding to the first communication link for the data to be transmitted includes:
step A10, determining a second communication device corresponding to the target communication device according to the networking information of the wireless ad hoc network;
step a20, determining a second communication link between the target communication device and the second communication device;
step a30, matching the first link identifier of the first communication link with the second link identifier of the second communication link to obtain the target communication link.
In this embodiment, it should be noted that, because the topology structure of the wireless ad hoc network is complex, there are multiple communication links between communication devices, and further, in the data transmission process, in order to ensure accuracy and efficiency of data transmission, targeted matching of a target communication link may be implemented based on existing information of the wireless ad hoc network.
Additionally, it should be noted that the networking information is used to characterize a networking situation between each communication device of the wireless ad hoc network, and may specifically be a periodically broadcasted networking message. The second communication device corresponding to the target communication device can be obtained through inquiry of the networking information, a communication link (second communication link) between the second communication device and the target communication device can be obtained, and finally the target communication link for transmitting the data to be transmitted can be obtained through the consistency pairing of the first communication link and the second communication link. The first link identifier and the second link identifier are used to represent link identifiers of different communication links, and the link identifiers are used to identify communication links between communication devices of the wireless ad hoc network, specifically, a local area network name or a local area network address.
As an example, steps a10 to a30 include: periodically receiving networking information of the wireless ad hoc network, and analyzing the networking information to obtain second communication equipment corresponding to the target communication equipment, wherein the second communication equipment is one or more specifically; taking at least one initial communication link between the target communication device and the second communication device as each second communication link, wherein the initial communication link is used for representing a communication link between the target communication device and the second communication device after the wireless ad hoc network is established and stabilized; and comparing the first link identification of the first communication link with the second link identification of each second communication link one by one, and taking the second communication link corresponding to the second link identification which is the same as the first link identification as the target communication link.
Wherein the step of determining a second communication link between the target communication device and the second communication device comprises:
step B10, regarding an initial communication link between the target communication device and the second communication device as the second communication link; or the like, or, alternatively,
and step B20, taking the initial communication link between the target communication device and the second communication device and the standby communication link corresponding to the target communication device as the second communication link.
In this embodiment, it should be noted that, in the symmetric multilink communication process, the topology of the wireless ad hoc network is in dynamic change. In order to ensure that each second communication link between the communication device and the second communication device can still be matched to the target communication link with the same link bandwidth as the first communication link after the dynamic change, the initial communication link and the candidate communication link can be used as the second communication link to increase the matching amount. For example, referring to fig. 6, fig. 6 is a schematic diagram illustrating a symmetrical multilink before and after a topology structure of the wireless ad hoc network changes, where the slave communication device 12 is a target communication device, the master communication device 11 is a higher-level device of the slave communication device 12, and the slave communication device 13 and the slave communication device 14 are drop-in devices of the slave communication device 12, where the communication link d, the communication link e, the communication link f, the communication link g, the communication link h, and the communication link i are initial communication links, and the communication link j, the communication link k, and the communication link l are standby communication links.
As an example, steps B10 to B20 include: taking an initial communication link between the target communication device and the second communication device as the second communication link; or the like, or, alternatively,
and acquiring alternative communication links between the target communication device and the first communication device in different networking modes of the target communication device and the second communication device, and taking an initial communication link and the alternative communication link between the target communication device and the second communication device as the second communication link together.
Before the step of obtaining the data to be transmitted, which is transmitted by the first communication device through the first communication link, the symmetric link data transmission method further includes:
step C10, if receiving the standby networking request of the wireless ad hoc network, acquiring at least one networking communication device of the target communication device;
and step C20, establishing standby communication links between the target communication equipment and each networking communication equipment respectively.
In this embodiment, it should be noted that a primary communication device of the wireless ad hoc network initiates a backup networking request, where the networking communication device is configured to characterize a communication device performing backup networking with the target communication device. In order to cope with the same-bandwidth data transmission requirements of the wireless ad hoc network under different topologies, standby communication links can be established for the target communication device and the networking communication device in a targeted manner.
As an example, steps C10 to C20 include: after the wireless ad hoc network is established and stabilized, if a standby networking request sent by the main communication equipment is received, at least one networking communication equipment of the target communication equipment is obtained; and establishing standby communication links between the target communication equipment and each networking communication equipment respectively.
Wherein the backup communication link includes a backup wireless link and a backup wired link, and the step of establishing the backup communication link between the target communication device and each of the networking communication devices respectively includes:
step D10, the standby wireless links are respectively established for the target communication equipment and each networking communication equipment; and/or
Step D20, establishing the standby wired link for the target communication device and each networking communication device, respectively.
In this embodiment, it should be noted that the backup communication link includes a backup wireless link and a backup wired link, and in order to ensure normal transmission of the multilink after the topology structure of the wireless ad hoc network is changed, the backup communication link may be established by establishing the wired communication link and the wireless communication link in different communication frequency bands, respectively.
As an example, steps D10 to D20 include: respectively establishing a 2.4GHz frequency band standby communication link for the target communication device and each networking communication device, and respectively establishing a 5GHz frequency band standby communication link for the target communication device and each networking communication device; and/or
And establishing the standby wired link for the target communication equipment and each networking communication equipment respectively.
Wherein the target communication link comprises a target wireless link and a target wired link, and the step of transmitting the data to be transmitted to the second communication device through the target communication link comprises:
step E10, transmitting the data to be transmitted to the second communication device through the target wireless link; or the like, or a combination thereof,
and E20, transmitting the data to be transmitted to the second communication equipment through the target wired link.
In this embodiment, it should be noted that when the target communication device transmits data to be transmitted to the second communication device, a target wireless link (target wireless communication link) or a target wired link (target wired communication link) may be adopted for targeted transmission according to an actual data transmission requirement, where the target wireless link may be a 2.4GHz band communication link or a 5GHz band communication link, and the like.
As an example, steps E10 to E20 include: transmitting the data to be transmitted to the second communication device through a 2.4GHz frequency band communication link; or the like, or, alternatively,
and transmitting the data to be transmitted to the second communication device through the target wired link.
The embodiment of the application provides a symmetric link data transmission method, which is applied to target communication equipment of a wireless ad hoc network, namely, data to be transmitted, which is transmitted by first communication equipment through a first communication link, is acquired, wherein the first communication link is a communication link between the target communication equipment and the first communication equipment; matching a target communication link corresponding to the first communication link for the data to be transmitted, wherein the link bandwidths between the target communication link and the first communication link are the same; and transmitting the data to be transmitted to second communication equipment through the target communication link. Due to the fact that the link bandwidths between the target communication link and the first communication link are the same, when the target communication device obtains the data to be transmitted from the first communication device through the first communication link, the purpose of transmitting the data to be transmitted to the second communication link through the target communication link can be achieved. That is, the purpose of transmitting communication data from the upper level device of the communication device to the lower level device of the communication device through the communication link with the same link bandwidth is achieved. Instead of when the communication device transmits communication data, one communication link is arbitrarily selected to transmit the communication data from the upper level device of the communication device to the lower level device of the communication device via the communication device. Therefore, the technical defect that communication data are lost when the communication equipment normally receives communication data transmitted by the superior equipment of the communication equipment and transmits the communication data to the lower hanging equipment of the communication equipment through a certain communication link between the communication equipment and the lower hanging equipment of the communication equipment due to the fact that a plurality of communication links exist among the communication equipment, the superior equipment of the communication equipment and the lower hanging equipment of the communication equipment is overcome. Therefore, the data transmission accuracy in the link communication process is improved.

The candidate communication devices are one or more than one, and the second communication device is a device for receiving the determined data to be transmitted, so that when a plurality of candidate communication devices of the target communication device in the wireless ad hoc network are provided, the second communication device is determined in the candidate communication devices according to a data identifier carried by the data to be transmitted, wherein the data identifier specifically can be a data receiving local area network address or a data receiving local area network name and the like.
As an example, steps F10 to F30 include: using networking information of the wireless ad hoc network as an index, and inquiring candidate communication equipment for transmitting the data to be transmitted together with the target communication equipment, wherein the candidate communication equipment comprises first candidate communication equipment and second candidate communication equipment, the first candidate communication equipment is used for representing one candidate communication equipment, and the second candidate communication equipment is used for representing a plurality of candidate communication equipment; if the candidate communication device is a candidate communication device, taking the candidate communication device as the second communication device; and if the candidate communication equipment is a plurality of candidate communication equipment, taking the candidate communication equipment consistent with the data identification carried by the data to be transmitted as the second communication equipment.
The embodiment of the application provides a second communication device determining method.
