[0032] Step S202, determining network quality parameters of a plurality of wireless sub-networks corresponding to a wireless device, wherein the network coverage of the plurality of wireless sub-networks all includes the wireless device;

[0033] It should be noted that the wireless sub-network can be understood as a Umesh network, and the wireless device can be understood as a Umesh device supporting the Umesh network protocol, but is not limited thereto.

[0034] Step S204, determining a first network quality value of each of the plurality of wireless sub-networks according to the network quality parameter of the wireless sub-network, and determining a maximum network quality value from the first network quality values of the plurality of wireless sub-networks;

[0036] Step S208, in a case where the network identifier of the target sub-network exists in the wireless network identifier record, determining the target sub-network as the target wireless network to be joined by the wireless device.

[0037] Through the above steps, the network quality parameter of the plurality of wireless sub-networks corresponding to the wireless device is determined, wherein the network coverage of the plurality of wireless sub-networks includes the wireless device; a first network quality value of each of the plurality of wireless sub-networks is determined according to the network quality parameter of the wireless sub-network, and a maximum network quality value is determined from the first network quality values of the plurality of wireless sub-networks; the network identifier of the target sub-network corresponding to the maximum network quality value is determined, and the wireless network identifier record of the wireless device when performing the network setting is obtained; in a case where the network identifier of the target sub-network exists in the wireless network identifier record, the target sub-network is determined as the target wireless network to be joined by the wireless device, thereby solving the problem of how to determine the target wireless network to be joined by the wireless device in the related art, and the target wireless network to be joined by the wireless device can be determined.

[0038] Based on the above embodiment, the target sub-network can be determined according to the maximum value of the first network quality values of the plurality of wireless sub-networks, and whether the target sub-network is the target wireless network to be joined by the wireless device is determined by taking whether the network identifier of the target sub-network exists in the wireless network identifier record as a condition, thereby not only enriching the determination process of the target wireless network, but also improving the accuracy of determining the target wireless network.

[0039] In one exemplary embodiment, for how to determine the network quality parameter of the plurality of wireless sub-networks corresponding to the wireless device in the above step S202, a technical solution is proposed, and the specific steps include: for any wireless sub-network of the plurality of wireless sub-networks, determining the preference value corresponding to the root node of the any wireless sub-network, the node signal strength of the target node of the any wireless sub-network, and the node quantity of the any wireless sub-network; and obtaining the network quality parameter of the plurality of wireless sub-networks according to the preference value corresponding to the root node of the any wireless sub-network, the signal strength of the target node of the any wireless sub-network, and the node quantity of the any wireless sub-network.

[0040] Further, the process for determining the preference value corresponding to the root node of any wireless sub-network comprises: obtaining the device factory data of the wireless device corresponding to the root node, determining the device memory of the wireless device, the network bandwidth of the wireless device and the power supply type of the wireless device from the device factory data; determining the preference value of the root node from the preset preference value according to the corresponding relationship between the preference value of the root node and the device memory, the network bandwidth and the power supply type. Wherein, the preference value of the root node is in direct proportion to the device memory and the network bandwidth, the power supply type comprises continuous power supply and non-continuous power supply, and the wireless device supporting continuous power supply has a higher preference value than the wireless device supporting non-continuous power supply.

[0041] In an exemplary embodiment, further, a technical solution for how to determine the signal strength of the target node of any wireless sub-network is proposed, and the specific steps are as follows: obtaining the monitoring history record of the signal strength of all nodes in the wireless sub-network, obtaining the first node with the maximum signal strength from the monitoring history record, and obtaining the signal strength of the first node of the wireless sub-network, wherein the first node is the target node; or determining the second node with the minimum distance from the monitoring device from all nodes in the wireless sub-network, and obtaining the signal strength of the second node of the wireless sub-network, wherein the second node is the target node, and the monitoring device is a device for monitoring the signal strength of the nodes in the wireless sub-network.

[0042] Wherein, the above monitoring history record can include the historical monitoring value of the node and the signal strength, for example, for node A, the historical monitoring value of the signal strength of node A includes (Monday, 60dbm), (Tuesday, 61dbm), (Wednesday, 62dbm), (Thursday, 60dbm), (Friday, 60dbm).

[0043] It should be noted that the above monitoring device can be understood as a device for monitoring the signal strength of all nodes in any wireless sub-network, which is configured with, for example, infrared monitoring device, sound wave monitoring device, etc., and can be the above wireless device or professional monitoring device, which is not limited in the present application.

[0044] In an example embodiment, for implementing the process of determining the first network quality value of each of the plurality of wireless sub-networks according to the network quality parameters of the plurality of wireless sub-networks in step S204, the following technical solution is proposed, specifically comprising: determining a first product of a preference value corresponding to a root node of any one of the plurality of wireless sub-networks and a weight coefficient of the preference value; determining a second product of a node quantity of the any one of the plurality of wireless sub-networks and a weight coefficient of the node quantity; obtaining a difference value between the first product and the second product, and determining a sum value between the difference value and a node signal strength of a target node of the any one of the plurality of wireless sub-networks as the first network quality value of the any one of the plurality of wireless sub-networks.

[0045] In an example embodiment, further, after determining the first network quality value of each of the plurality of wireless sub-networks according to the network quality parameters of the plurality of wireless sub-networks, at least one second network quality value greater than a preset network quality value can be obtained from the first network quality values of the plurality of wireless sub-networks; and the obtained at least one second network quality value is determined as the network quality value of the plurality of wireless sub-networks.

[0046] Optionally, before obtaining at least one second network quality value greater than a preset network quality value from the first network quality values of the plurality of wireless sub-networks, the preset network quality value is obtained, wherein the preset network quality value can be determined according to historical network records or specified by a user, and the present application does not limit this.

[0047] For the process of obtaining at least one second network quality value greater than a preset network quality value from the first network quality values of the plurality of wireless sub-networks, the first network quality values of the plurality of wireless sub-networks can be sorted in size first, and then each first network quality value of each wireless sub-network is compared with the preset network quality value in sequence according to the sorting result until all first network quality values of all wireless sub-networks are compared with the preset network quality value. Alternatively, the first network quality value greater than the preset network quality value for the first time can be directly determined as the second network quality value. The present application does not limit this.

[0048] Further, for the plurality of second network quality values, the largest second network quality value is determined as the network quality value of the plurality of wireless sub-networks.

[0049] In other embodiments, if a fourth network quality value less than the preset network quality value is obtained from the first network quality values of the plurality of wireless sub-networks, it is determined that the network status of the wireless sub-network having the fourth network quality value is unqualified, the wireless sub-network having the fourth network quality value is deleted from the plurality of wireless sub-networks, and a target wireless network is determined from the plurality of wireless sub-networks after the wireless sub-network having the fourth network quality value is deleted.

[0050] In one example embodiment, for the process of determining the target sub-network as the target wireless network to be joined by the wireless device in step S206, the following steps can be used: determining a third network quality value of a wireless network that has connected to a server and to which the wireless device also corresponds; obtaining the maximum network quality value from the third network quality value and the first network quality value; and determining the target sub-network corresponding to the maximum network quality value as the target wireless network to be joined by the wireless device.

[0051] In one example embodiment, a method of determining the target sub-network corresponding to the maximum network quality value as the target wireless network to be joined by the wireless device is provided, which specifically includes: in a case where the target sub-network corresponding to the maximum network quality value includes a wireless network that has connected to a server, obtaining other preference values corresponding to root nodes of other target sub-networks in the plurality of target sub-networks except the wireless network that has connected to the server; in a case where the preset preference value of the wireless device is greater than the other preference values, joining the wireless network that has connected to the server and creating the target wireless network to be joined by the wireless device based on the wireless network that has connected to the server.

[0052] In one example embodiment, a method of determining the target sub-network corresponding to the maximum network quality value as the target wireless network to be joined by the wireless device is also provided, which specifically includes: in a case where the preset preference value of the wireless device is less than or equal to the other preference values, determining the other target sub-networks in the plurality of target sub-networks except the wireless network that has connected to the server as the target wireless network to be joined by the wireless device.

[0053] In one example embodiment, in the process of determining the first network quality values of the plurality of wireless sub-networks according to the network quality parameters of the plurality of wireless sub-networks, if the first network quality values of the plurality of wireless sub-networks are all less than the preset network quality value, the wireless device creates a target wireless network to be joined by the wireless device if the device type of the wireless device is a root node; and controls the wireless device to perform a sleep operation, and after the sleep operation ends, re-determines the target wireless network to be joined by the wireless device if the device type of the wireless device is a non-root node.

[0054] In order to better understand the process of the above-mentioned target wireless network determination method, the implementation method flow of the above-mentioned target wireless network determination will be described in combination with optional embodiments below, but not used to limit the technical solutions of the embodiments of the present application.

[0055] In the present embodiment, a schematic diagram of the architecture of the target wireless network is provided. In the present embodiment, when there is a whole-house basic network (equivalent to the above-mentioned wireless network having connected to the server) in a user's home, each UMesh sub-network (equivalent to the above-mentioned wireless sub-network) in the user's home is connected to the whole-house basic network through a sub-network root node, as shown in Figure 3 Figure 3 is a schematic diagram of the architecture of the target wireless network according to the embodiments of the present application. In the topology of the UMesh network, each UMesh sub-network root node has two interfaces: one interface (ROOT1 / ROOT2 / ROOT3) is located in the whole-house basic network and is connected to a traditional router in the whole-house basic network via Wi-Fi or Ethernet, which is called the external network interface of the UMesh root node; and the other interface is located in the UMesh sub-network and is connected to the nodes in the UMesh sub-network via Wi-Fi Mesh, which is called the sub-network interface of the UMesh root node (not shown). Figure 3 Figure 3

[0056] All UMesh root nodes can interconnect and interoperate in the whole-house basic network based on IPv6 through the respective external network interfaces, and complete the cooperation and inter-network data communication between the UMesh sub-networks through the UMesh management protocol.

[0057] For example, the UMesh root node can configure a ULA format unicast address on the external network interface, and join the UMesh root node multicast group (FF13::101). The construction rule of the corresponding ULA format unicast address prefix may, for example, include:

[0058] 1. The fixed prefix is FD00: / 8;

[0059] ​​​2. Global ID is a 40-bit random ID derived from the UMesh network ID.

[0060] 3. Subnet number is fixed as 1.

[0061] Then, the ULA (Unique Local IPv6 Unicast Addresses [RFC4193]) unicast address of the external interface of the UMesh root node can be formed by combining the above prefix and the interface identifier of the UMesh root node.

[0062] Optionally, the external interface of the UMesh root node does not need to perform SLAAC (Stateless Address Autoconfiguration) and should ignore the PIO (Prefix Information Option) information in the RA (Router Advertisement Message) message.

[0063] It should be noted that the unicast address of the subnet interface of the UMesh root node can be understood as the inter-network unicast address of the UMesh root node.

[0064] In one embodiment, a determination method of the above target wireless network is proposed in combination with the following steps, and the quality values of the multiple UMesh subnets and the whole-house basic network can be calculated respectively, and the optimal access network (i.e., the target wireless network) can be selected by comparison.

[0065] For devices representing non-root nodes, the whole-house basic network can be skipped, and only the UMesh subnet quality can be calculated.

[0066] The specific implementation steps are as follows:

[0067] Step 1. Four parameters are required for the quality judgment of each UMesh subnet:

[0068] Parameter 1. UMesh network ID of each UMesh network. Before accessing the network, it is necessary to determine whether the UMesh network ID to be accessed is consistent with the UMesh network ID obtained by the node itself through the UMesh network binding process. If not, it is not possible to attempt to join the UMesh, and the UMesh subnet needs to be directly shielded in the subsequent calculation process.

[0069] Parameter 2, each UMesh subnet should have a preference value (up), which should be preset in the root node of the UMesh subnet, indicating whether the root node should be more preferentially selected as a root node. The preference value should be embodied in the Prf of the DIO packet, and the value range is 0-7. For example, a screen-equipped device should have a higher preference value (such as 7), and a wireless module of a washing machine should have a lower preference value (such as 0).

[0070] Parameter 3, the signal strength of the best node in each UMesh subnet (us).

[0071] Parameter 4, the number of nodes in each UMesh subnet (the value should roughly reflect the load of the subnet) (un).

[0072] In an embodiment, the quality value of the UMesh subnet (equivalent to the first network quality value described above) can be calculated according to the following formula: let the signal strength of the best node in the UMesh subnet be us, the preference value of the root node of the UMesh subnet be up, and the number of nodes in the UMesh subnet be un, then the quality value uq of the UMesh subnet can be calculated according to the following formula:

[0073] uq = us + (kp * up) - (kn * un).

[0074] Wherein, kp is a constant representing the weight of the preference value, which is recommended to be 10 here. kn is a constant representing the weight of the number of nodes, which can be 5, for example.

[0075] Step 2, the quality value rq of the whole-house basic network is the signal strength of the best router in the whole-house basic network.

[0076] Step 3, the quality value of the network has a minimum value (qmin, equivalent to the preset network quality value described above), if the network is searched but the calculated quality value is less than the minimum value, it indicates that the network state is very poor and cannot be accessed, and the network should be ignored in the process of networking. Qmin can be set to -100, for example.

[0077] Step 4, calculate the uq of all UMesh subnets around the wireless device and the rq of the whole-house basic network, and select the network corresponding to the maximum value of uq and rq. If the network corresponding to the maximum value is a UMesh network, directly join the network corresponding to the maximum value, if the network corresponding to the maximum value is the whole-house basic network, connect the whole-house basic network and negotiate the subnet number, and after successfully obtaining the subnet number, send DIO and start creating a UMesh subnet.

[0078] Step 5, whether the connection of the whole house basic network fails or the negotiation of the subnet number fails, the connection to the whole house basic network is abandoned, and the joining of the UMesh subnet is attempted.

[0079] Step 6, if the whole house basic network and the UMesh subnet with the same quality value exist around the device, the device should first compare the preference value of itself with the preference value of the UMesh subnet, if the preference value of itself is greater than the preference value of the UMesh subnet, the device should access the whole house basic network to attempt to create a new UMesh subnet, otherwise (the preference value of itself <= the preference value of the UMesh subnet) the device should join the UMesh subnet.

[0080] Step 7, if the optimal access network is not found (i.e. no UMesh subnet or whole house basic network with quality up to the standard exists around), for the wireless device corresponding to the root node, the UMesh network without the whole house basic network should be attempted to be established, for the wireless device corresponding to the non-root node, the device needs to be in silence and sleep for a period of time, and then the network establishment is restarted.

[0081] Step 8, if the joining of the optimal access network fails, the device needs to be in silence and sleep for a period of time, and then the network establishment is restarted.
