In order to better understand the above technical solutions, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to better understand the technical scheme, the technical scheme is described in detail in the following with reference to the attached drawings of the specification and specific embodiments.
Example one
Fig. 1 is a schematic flowchart of a communication method based on a Mesh network according to an embodiment of the present application.
In the embodiment of the application, the communication method based on the Mesh network is applied to the Mesh network, and the Mesh network comprises a plurality of outlet communication modules. The outlet communication module is a communication module that can access the internet through a connection mode other than the Mesh network, for example, a communication module that is connected to the network through a wired broadband or a wireless router. The communication module may be a communication module disposed in the household appliance, and may be, for example, a Wireless-Fidelity (WiFi) module.
The home appliances include, but are not limited to, air conditioners, televisions, refrigerators, and other home appliances.
As shown in fig. 1, the Mesh network-based communication method includes the following steps:
In the embodiment of the application, when communication is performed through the Mesh network, a communication module in the Mesh network can acquire a data packet to be transmitted. The communication module may be an egress communication module or a non-egress communication module, and is not limited herein.
As an example, the communication module may obtain a data packet to be sent of the home device. For example, taking a digital television in a Mesh network as an example, the digital television includes a communication module 1, the digital television needs to send a data packet when connecting to a network for requesting a program, and the communication module 1 acquires the data packet to be sent by the digital television.
As another example, when the communication module is used to provide a network to other user equipment, the communication module may further obtain a data packet to be sent of the user equipment. For example, the communication module is configured to provide a network in a relay mode or an Access Point (AP) mode, and when a user connects to the communication module through a mobile phone to surf the internet, the communication module obtains a data packet to be sent by the mobile phone.
And 102, determining a target outlet communication module corresponding to the data packet according to the preset transmission probability.
In the embodiment of the present application, since the Mesh network includes a plurality of egress communication modules, that is, the Mesh network may access a plurality of bandwidth sources, for example, the Mesh network includes egress communication modules 1 and 2, the egress communication module 1 is connected to a wired broadband, and the egress communication module 2 is connected to a router. Therefore, after the communication module acquires the data packet to be sent, the corresponding target outlet communication module can be determined according to the preset transmission probability, so that the bandwidth source corresponding to the data packet is determined.
As an example, the transmission probability may be determined from bandwidth traffic information of each egress communication module. For example, network bandwidth and traffic information of each egress communication module may be obtained, and the larger the traffic of the egress communication module is, the smaller the network bandwidth is, and the lower the corresponding transmission probability is.
As another example, the transmission probability may be determined based on link quality information of the communication module and each egress communication module. For example, the higher the link quality between the communication module and the egress communication module, the higher the corresponding transmission probability. Wherein the link quality of the communication module and the egress communication module may be a quality of a link between the communication module and a bandwidth source corresponding to the egress communication module.
It should be noted that, the implementation manner of determining the transmission probability is merely exemplary, and the transmission probability may also be set according to actual requirements, which is not limited herein.
As a possible implementation manner, the communication module may select, according to a preset transmission probability, a corresponding egress communication module as a target egress communication module according to the probability. For example, if the transmission probabilities corresponding to egress communication modules a and B are both 50%, the egress communication module a is selected as the target egress communication module with a probability of 50%, and the egress communication module B is selected as the target egress communication module with a probability of 50%.
As another possible implementation manner, the communication module may determine, according to a preset transmission probability, an egress communication module with the highest transmission probability as the target egress communication module. For example, if the transmission probabilities corresponding to egress communication modules a and B are 30% and 20%, respectively, egress communication module a is determined to be the target egress communication module corresponding to the data packet.
And 103, sending the data packet to the target outlet communication module.
In the embodiment of the application, after the target outlet communication module corresponding to the data packet is determined according to the preset transmission probability, the data packet can be sent to the target outlet communication module, so that the data packet is transmitted to the bandwidth source connected with the target outlet communication module. Therefore, when the Mesh network comprises a plurality of outlet communication modules, the outlet communication modules corresponding to the data packets are determined through the transmission probability, the multi-broadband concurrent communication of the Mesh network is realized, a plurality of bandwidth resources can be effectively utilized to surf the internet, and the network speed is improved.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
due to the adoption of the method and the device, the data packet to be sent is obtained, the target outlet communication module corresponding to the data packet is determined according to the preset transmission probability, and the data packet is sent to the target outlet communication module, so that the problem that partial bandwidth resources are idle because a Mesh node only surfs the internet through one bandwidth source when a plurality of bandwidth sources exist in the Mesh network in the related art can be effectively solved, the multi-bandwidth parallel communication of the Mesh network is realized, a plurality of bandwidth resources can be effectively utilized to surf the internet, and the network speed is improved.
Based on the foregoing embodiment, the communication module may establish a routing table, and send the data packet to the corresponding egress communication module according to the default routing rule in the routing table, and the foregoing process is described in detail below with reference to the second embodiment.
Example two
Fig. 2 is a schematic flowchart of a communication method based on a Mesh network according to a second embodiment of the present application.
As shown in fig. 2, the Mesh network-based communication method may include the steps of:
In the embodiment of the application, each communication module in the Mesh network detects the network connection state of the module, and broadcasts the network connection state of the module to other communication modules through the Mesh network, and then each communication module receives the network connection state of other communication modules. The network connection state may include a connection state of the communication module with a wired broadband, a router, a wireless AP, and the like.
As an example, the communication module detects the network connection state of the module, and when the communication module detects that the module is wirelessly connected with a router, the communication module generates a network connection state a and sends the network connection state a to other communication modules in a Mesh network through Mesh network broadcasting; and when detecting that the module is connected with other equipment only through the Mesh network, generating a network connection state B and sending the network connection state B to other communication modules in the Mesh network through the Mesh network broadcast.
In this embodiment of the application, the communication module determines, according to the received network connection state of each other communication module in the Mesh network, an egress communication module according to the network connection state, for example, determines that the communication module whose network connection state is a is the egress communication module. The exit communication module may be a communication module that can access the internet through a connection mode other than the Mesh network, for example, a communication module that is connected to the network through a wired broadband or a wireless router.
As a possible implementation manner, after determining the egress communication module, the communication module may establish a routing table corresponding to the egress communication module. For example, a routing table may be established for each egress communication module, with a one-to-one correspondence to the egress communication module.
The explanation of step 101 in the foregoing embodiment is also applicable to step 203, and is not described herein again.
And 204, determining a target outlet communication module corresponding to the data packet according to the preset transmission probability.
In the embodiment of the application, the routing table queried when the data packet is sent can be determined according to the preset transmission probability, so that the target outlet communication module corresponding to the data packet is determined according to the routing table.
As a possible implementation manner, bandwidth flow information and link quality information of each egress communication module may be obtained, and then, according to the bandwidth flow information and the link quality information, a transmission probability corresponding to each egress communication module is determined by a correlation algorithm. For example, network bandwidth, traffic information, and link quality information of each egress communication module may be obtained, where the larger the traffic of the egress communication module is, the smaller the network bandwidth is, and the lower the link quality between the communication module and the egress communication module is, the lower the corresponding transmission probability is. Wherein the link quality of the communication module and the egress communication module may be a quality of a link between the communication module and a bandwidth source connected to the egress communication module.
In the embodiment of the present application, a default routing rule may be added in advance in the routing table. The default routing rule is a routing rule that can match any destination ip address in a routing table, and the data packet can be directed to an exit communication module corresponding to the routing table through the default routing rule.
As an example, after a data packet to be sent is obtained, a routing table queried by the data packet may be determined according to a preset transmission probability, and then a default routing rule in the routing table is obtained by querying the routing table, and the data packet is sent to the egress communication module according to the default routing rule.
Compared with the previous embodiment, the technical solution in the embodiment of the present application at least has the following further technical effects or advantages:
on one hand, the bandwidth flow information and the link quality information of each outlet communication module are obtained, and then the transmission probability corresponding to each outlet communication module is determined according to the bandwidth flow information and the link quality information, so that the utilization rate of bandwidth resources can be improved, and the network speed is improved.
On the other hand, due to the adoption of the default routing rule in the routing table corresponding to the target outlet communication module, the data packet is sent to the outlet communication module according to the default routing rule, so that the effective utilization of a plurality of broadband resources for surfing the internet is realized, and the network speed is improved.
Based on the above embodiment, before communication is performed through the Mesh network, the communication module may also be configured according to the route configuration parameter and the Mesh configuration parameter, so as to implement networking in the communication mode + the Mesh mode, which is described in detail below with reference to the third embodiment.
EXAMPLE III
Fig. 3 is a schematic flowchart of a communication method based on a Mesh network according to a third embodiment of the present application.
As shown in fig. 3, the Mesh network-based communication method may include the steps of:
In the embodiment of the application, when the communication module performs network configuration, a routing configuration parameter and a Mesh configuration parameter of a wireless Mesh network need to be acquired.
As an example, a user may obtain a routing configuration parameter and a Mesh configuration parameter of a wireless Mesh network through a mobile terminal such as a mobile phone, so as to establish communication between the mobile terminal and a communication module, and send the routing configuration parameter and the Mesh configuration parameter to the communication module. The routing configuration parameter and the Mesh configuration parameter may be pre-stored in the mobile terminal, or a related application program may be set in the mobile terminal, and the routing configuration parameter and the Mesh configuration parameter are obtained through the application program, which is not limited herein.
As a possible implementation manner, the routing configuration parameter may include a Service Set Identifier (SSID) and a password corresponding to the SSID. The SSID may be a character string composed of numbers and letters.
As a possible implementation manner, the Mesh configuration parameters may include a Basic Service Set Identifier (BSSID), a channel, an encryption manner, and a password corresponding to the BSSID. The BSSID may be a character string composed of numbers and letters.
In the embodiment of the application, the target router may be a router connected to the internet in a home of the user.
As an example, the routing configuration parameters include SSID and password, where SSID and router have one-to-one correspondence, that is, the target router may be determined according to the routing configuration parameters. After receiving the SSID and the password, the communication module may determine a target router corresponding to the SSID according to the SSID, for example, the communication module obtains the SSID of each router through scanning, matches the SSID with the received SSID, and then determines that the router corresponding to the SSID with the matching result is the target router.
In the embodiment of the present application, the communication mode includes, but is not limited to, a relay mode, an Access Point (AP) mode, and the like.
As an example, the communication mode of the communication module may be determined according to the signal strength of the target router. For example, a signal strength threshold value may be set in advance, and when the signal strength of the target router detected by the communication module is equal to or greater than the threshold value, the communication module is set to a relay mode in which the target router can be connected according to the SSID and the password. As a possible implementation manner, the communication module is wirelessly connected with the target router; and when the signal strength of the target router detected by the communication module is less than the threshold value, setting the communication module to be in the AP mode.
As another example, the communication mode of the communication module may also be determined according to the distance of the communication module from the target router. For example, a preset distance may be preset, the distance between the communication module and the target router may be detected, and when the detected distance is less than or equal to the preset distance, the communication module may be set to the relay mode; and when the detected distance is greater than the preset distance, setting the communication module to be in the AP mode.
And step 304, adding the target communication module into the Mesh network according to the Mesh configuration parameters.
As an example, taking Mesh configuration parameters including BSSID, channel, encryption manner, and password as an example, when receiving the Mesh configuration parameters, the communication module determines a corresponding Mesh network according to the BSSID, and adds the communication module to the Mesh network according to the channel, the encryption manner, and the password.
It should be noted that, in the embodiment of the present application, the communication module may also join the Mesh network according to the Mesh configuration parameter, and then determine the corresponding target router according to the route configuration parameter, and further configure the communication module into the corresponding communication mode, where the configuration sequence is not limited herein.
In the embodiment of the application, the communication module can configure according to the received Mesh configuration parameters so as to join in the Mesh network. For example, a relay mode communication module may join the Mesh network, thereby configuring a relay + Mesh mode. For another example, the communication module in the AP mode may join the Mesh network, and thus be configured in the AP + Mesh mode. The communication module in the relay + Mesh mode is connected with the router, amplifies and forwards received router wireless signals through a relay function so as to provide a network for user equipment, and is connected with other communication modules through a Mesh network; the communication module of the AP + Mesh mode may be connected with other communication modules through a Mesh network to receive a network through the Mesh network and provide the network to the user equipment through the AP function.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
the method comprises the steps of obtaining a route configuration parameter and a Mesh configuration parameter of the wireless Mesh network, determining a target router corresponding to a communication module according to the route configuration parameter, configuring the communication module into a target communication module with a corresponding communication mode according to the target router, and adding the target communication module into the Mesh network according to the Mesh configuration parameter, so that the technical problem that the coverage of wireless signals in the related technology needs to be improved is effectively solved, the networking mode of the communication mode of the household appliance and the Mesh mode is realized, the household appliance can provide a network for user equipment through the communication module, and the coverage of the wireless signals is improved.
Based on the above embodiments, the communication module may determine the configured communication mode according to the detected signal strength radiated by the target router, and the above procedure is described in detail with reference to the fourth embodiment.
Example four
Fig. 4 is a schematic flowchart of a communication method based on a Mesh network according to a fourth embodiment of the present application.
As shown in fig. 4, the Mesh network-based communication method may include the steps of:
The explanation of step 301 in the foregoing embodiment is also applicable to step 401 in this embodiment, and is not described herein again.
As an example, the user may also trigger the distribution network mode request of the communication module on the home device through a remote control key or a physical key on the home device. Furthermore, after receiving the distribution network mode request, the electric control board on the household appliance sends the distribution network mode request to the communication module through the communication interface, so that the communication module enters the distribution network mode after receiving the request and waits for receiving the routing configuration parameters and the Mesh configuration parameters. The form of the communication interface between the electronic control board and the communication module may be a serial port or others, which is not limited herein.
The explanation of step 302 in the foregoing embodiment is also applicable to step 402 in this embodiment, and is not described herein again.
In step 403, the signal strength radiated by the target router is detected.
In this embodiment of the application, the communication module may detect the signal strength radiated by the target router, so as to determine the communication mode according to the signal strength.
As a possible implementation manner, after the target router is determined, the signal strength radiated by the target router may be detected through a related wireless signal detection technology, or the signal strength of a router that can be currently searched by the communication module may be detected, and the signal strength of the target router is determined according to the routing configuration parameter, which is not limited herein.
In the embodiment of the present application, a signal strength threshold may be preset, the detected signal strength of the target router is compared with a preset signal strength threshold, and the communication mode of the communication module is determined according to the comparison result. The signal intensity threshold may be determined according to a large amount of experimental data, or may be set according to needs, which is not limited herein.
As an example, when the signal strength of the target router detected by the communication module is greater than or equal to the threshold, the communication module sets a relay mode, wherein the communication module in the relay mode is connected with the target router and amplifies and forwards the received wireless signal of the target router to provide a network for the user equipment, thereby improving the wireless signal coverage.
As another example, when the signal strength of the target router detected by the communication module is less than the threshold, the communication module is set to the AP mode, wherein the communication module in the AP mode is connected with other communication modules and provides a network to the user equipment through the AP function, thereby improving the coverage of the wireless signal.
As still another example, there may be a case where the communication module does not detect the target router signal, for example, when the communication module matches the obtained SSID of each router according to the received SSID and the matching result is non-existent, the communication module does not detect the target router signal. When the communication module does not detect the signal of the target router, the communication module may be set to the AP mode.
And step 405, adding the target communication module into the Mesh network according to the Mesh configuration parameters.
In the embodiment of the application, the communication module can configure according to the received Mesh configuration parameters to add into the Mesh network, so that a networking mode of a communication mode + a Mesh mode is realized. The relay + Mesh mode communication module is connected with the router, amplifies and forwards received router wireless signals through a relay function so as to provide a network for user equipment, and is connected with other communication modules through a Mesh network; the communication module of the AP + Mesh mode may be connected with other communication modules through a Mesh network to receive a network through the Mesh network and provide the network to the user equipment through the AP function.
Compared with the previous embodiment, the technical solution in the embodiment of the present application at least has the following further technical effects or advantages:
the method comprises the steps that the signal intensity radiated by a target router is detected, and when the signal intensity is larger than or equal to a preset threshold value, a communication module is set to be in a relay mode; when the signal intensity is smaller than the preset threshold value, the communication module is set to be in an access point mode, the target communication module is added into the Mesh network according to the Mesh configuration parameters, the communication module with the good signal coverage of the router is enabled to improve the wireless signal coverage through a relay mode, the communication modules are connected through the Mesh network to share network resources, the communication module with the poor signal coverage of the router is connected with other communication modules through the Mesh network and provides a network through an AP mode, and the signal intensity is guaranteed while the wireless signal coverage is improved.
EXAMPLE five
Fig. 5 is a schematic view of an application scenario provided in the embodiment of the present application.
In the embodiment of the application, the communication module may be a WiFi module, the WiFi module is disposed on the household appliance, and the communication mode includes a relay mode and an AP mode. The WiFi module 1 and the WiFi module 2 are in a relay + Mesh mode, and the WiFi module 3 is in an AP + Mesh mode. The WiFi module 1 and the WiFi module 2 are respectively in wireless connection with the router and can supply network to the mobile phone of the user through a relay mode. The WiFi modules share network resources through a Mesh network, and the WiFi module 3 can be connected with the network through the Mesh network and can supply network to a mobile phone of a user through an AP mode. In the figure, the user mobile phone is connected with the WiFi module 3 to surf the internet.
In the embodiment of the present application, taking the WiFi module 3 as an example, the WiFi module 3 determines that the WiFi modules 1 and 2 are outlet WiFi modules according to the network connection states broadcasted by the WiFi modules 1 and 2, and establishes a routing table. The routing table 1 corresponds to the WiFi module 1, the routing table 2 corresponds to the WiFi module 2, the default routing rule in the routing table 1 can guide the data packet to the WiFi module 1, and the default routing rule in the routing table 2 can guide the data packet to the WiFi module 2. For example, when a mobile phone sends a data packet, the WiFi module 3 obtains the data packet to be sent, and determines that the probabilities of querying the routing table 1 and the routing table 2 by the data packet are 50% respectively according to a pre-established firewall, and then selects one of the routing tables, for example, selects the querying routing table 1, sends the data packet to the WiFi module 1, and then transmits the data packet to a router connected to the WiFi module 1. For another example, when the household appliance device corresponding to the WiFi module 3 sends a data packet, the household appliance device determines to select the query routing table 2 according to the pre-established firewall, sends the data packet to the WiFi module 2, and then transmits the data packet to the router connected with the WiFi module 2. Therefore, the Mesh network multi-broadband concurrent communication can be realized, and a plurality of bandwidth resources can be effectively utilized to surf the internet, so that the network speed is improved.
Optionally, the firewall may also obtain information about the source of the packet, such as an identifier of the device sending the packet. And when a data packet to be sent is obtained, determining the routing table inquired by the data packet with the same historical source information according to the source information of the data packet, so that the data packet with the same source can inquire the same routing table.
It should be noted that the Mesh network connection shown in the figure is only an example, and in this embodiment, the egress communication module may also establish a routing table corresponding to each egress communication module, which is not limited herein.
