Detailed Description
The features of the present invention will become more apparent from the detailed description set forth below when taken in conjunction with the drawings.
With the continuous development of the smart home industry, more and more smart home devices can access to a home lan to implement interconnection (e.g., implement remote control of the smart home devices, upload data collected by the smart home devices, etc.). In order for a smart home device to be able to access a home local area network, for example, to communicate with other devices within an external network, the smart home device needs to know the SSID and password of the gateway of the home local area network ("surfing"). In the present invention, a process of transmitting the SSID and the password of the gateway to the smart home device so that the smart home device can connect to the gateway using the SSID and the password may be referred to as "distribution network". In order to facilitate networking of intelligent home equipment, a plurality of network distribution technologies are generated, and the problem that a single equipment is accessed to a wireless network is solved greatly. But at the same time other problems are derived: firstly, when SSID or password of the network connected with the networking equipment is changed, the network needs to be allocated one by one, and secondly, the intelligent home equipment connected with the wireless router with poor signal quality is expected to be switched to other wireless routers with better wireless signal quality. Therefore, the invention provides a method for realizing batch wireless network switching of intelligent home equipment, and further provides a method for automatically switching the intelligent home equipment to an optimal wireless network in a multi-wireless router multi-wireless network environment.
Fig. 1 illustrates an example of a network system 100 according to an embodiment of the invention. The network system 100 may include a home gateway 120 and at least one wireless router 130. The home gateway 120 may also be referred to as an gateway, a protocol converter, etc., and may be used to connect one network to another. In one embodiment, for example in the smart home domain, home gateway 120 may be a combination of "light cat" and "router" and be responsible for connecting to various types of smart home devices within the home. In one embodiment, the access point may support the IEEE 802.11Wi-Fi standard protocol. Those skilled in the art will appreciate that while home gateway 120 and one or more wireless routers 130 are shown in fig. 1 as distinct hardware, the present application also includes cases where both are integrated. It should be noted that the invention is not limited to the smart home field, but can be applied to any other field where it is necessary to implement a distribution network between smart home devices and gateways.
The network system 100 may also include one or more smart home devices 110-1 through 110-n (collectively referred to as smart home devices 110). It should be noted that while a limited number of smart home devices 110 are shown in fig. 1, the present invention is not limited to the smart home devices shown in the figures, but may include more smart home devices (depending on the capabilities of home gateway 120 and/or wireless router 130). In the present invention, smart home device 110 may refer to any device capable of connecting to a gateway via a wireless local area network protocol (e.g., wi-Fi), such as a smart camera, smart home device (smart speaker, smart television, smart refrigerator, smart washing machine, or other smart appliance), smart jack, smart phone, tablet, laptop, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, cellular phone, smart phone, session Initiation Protocol (SIP) phone, laptop, personal Digital Assistant (PDA), multimedia device, tablet, wearable device, or any other similar functional device.
The method can realize batch switching and automatic switching of the intelligent household equipment. In the example illustrated in fig. 1, for example, at least one smart home device 110 may join the wireless local area network via gateway 120 and/or router 130, and the user may wish to modify the SSID or password of some of the routers.
From the user's perspective, the user may operate a user operation surface on at least one user terminal 140, for example, an APP located on a smart terminal mobile phone, PAD, etc. used by the user, or a Web where the user connects to a gateway using a computer. Through this user plane the user can perform the following operations: altering wireless network information (e.g., SSID and/or password), selecting a corresponding wireless network, initiating a handover network instruction, etc.
The home gateway 120 may connect to the user plane to receive the switching instruction of the user, parse and forward to the smart home device 110 to be switched according to the need, and may connect to the smart home device through a wireless network (e.g., elink), thereby receiving the wireless network information of the smart home device, and decide whether to save the wireless network information and/or synchronize it to other smart home devices according to the need. Meanwhile, the home gateway 120 may synchronize the current wireless network information to the user plane for the user to select a wireless network. .
The smart home device 110 may synchronize its wireless network information to the home gateway 120 and receive wireless network information of other smart home devices 110 sent by the home gateway 120. The smart home device 110 may also determine whether to store locally based on wireless network information sent by the home gateway 120. The smart home device 110 may also receive and parse received wireless network switch instructions and perform network switching. The smart home device 100 may scan wireless network information of its surrounding coverage, and rank the corresponding networks according to network quality to select a network to connect. The following fig. 2 details process flows for implementing automatic synchronization, batch handoff, and automatic handoff between at least one smart home device 110 and wireless router 130, gateway 120.
Fig. 2A illustrates an example of a process flow of a method of automatically synchronizing wireless network information in a multi-wireless network environment according to an embodiment of the present invention, fig. 2B illustrates an example of a process flow of a method for implementing batch switching of smart home devices according to an embodiment of the present invention, and fig. 2C illustrates an example of a process flow of a method for implementing automatic switching of smart home devices according to an embodiment of the present invention. The above-described methods may be performed, for example, between one or more of the smart home devices 110-1 through 110-n, the gateway 120, the wireless router 130, and the user terminal 140 in fig. 1.
In one aspect of the present application, referring to fig. 2A, in an initial state, a gateway has established device associations with different wireless routers, respectively, forming a wireless network with different wireless network information (e.g., channel, SSID, password information, etc.). For example, a wireless network may be formed between gateway 220 and wireless routers 230-A and 230-B based on an elink protocol, IEEE 802.11a, or the like. Further, smart home device 210 has access to a first wireless network associated with wireless router 230-a. The smart home device 210 may periodically send its own wireless network information to the wireless router 220 or may send its own wireless network information in response to the triggering of the gateway 220/wireless router 230-a, and the smart home device 210 may have a local database to store wireless network information of other smart home devices forwarded by the respective routers, and the wireless routers 230-a and 230-B and the gateway 220 may also synchronize wireless network information of the smart home devices and store in the local database, as described in detail below. Further, it should be appreciated that while only one smart home device and two wireless routers are shown in fig. 2A, the present invention is not limited to the smart home devices/wireless routers shown in the figures, but may include more smart home devices/wireless routers.
In step 252, the wireless router 230-B may forward to the gateway 220 wireless network information (e.g., may include a channel, SSID, password, etc.) that is currently being used by other smart home devices in the second wireless network of the wireless router 230-B.
Gateway 220 may update its local database at step 254 and forward the wireless network information to wireless router 230-a at step 256. Additionally or alternatively, gateway 220 may communicate only wireless network information that is inconsistent with the local database (e.g., update the home wireless network information base if the wireless network information of the second wireless network is modified), thereby conserving network resources.
The wireless router 230-a may update its local database in response to receiving the wireless network information at step 258 and forward/broadcast the wireless network information to the corresponding connected smart home device 210 at step 260.
Subsequently, at step 262, the smart home device 210 may synchronize its local database in response to the received wireless network information.
Thus, the system of the invention can automatically synchronize the wireless network information in a multi-wireless network environment.
In another aspect of the present application, referring to fig. 2B, similar to fig. 2A, in an initial state, gateway 220 has established a device association with wireless router 230-a and smart home device 210 has access to a first wireless network associated with wireless router 230-a. It should be appreciated that while only a limited number of smart home devices and wireless routers are shown in fig. 2B, the present invention is not limited to the smart home devices/wireless routers shown in the figures, but may include more smart home devices/wireless routers.
At step 270, user 240 may initiate a network switch request. For example, the user may need to modify wireless network information (e.g., SSID and/or password) of the first wireless network of wireless router 230-a. It should be appreciated that if the new wireless network associated with wireless router 230-a after modifying the wireless network information is considered a wireless network to be handed over to, the above-described process of wireless network information modification may also be referred to herein as a "network handoff" process for the wireless access point (network and/or wireless router) and/or smart home device.
Subsequently, in step 272, the gateway may receive wireless network information to be handed off from the user. For example, a user may use an APP on a smart terminal handset, PAD, or the like to modify the SSID or password, etc. of wireless router 230-a and communicate the to-be-SSID or password to gateway 220. Additionally or alternatively, the user may modify the SSID or password, etc., of the wireless router 230-a through a Web computer connected to the gateway 220.
Gateway 220 may update its local database at step 274 and forward the wireless network information to be handed off to wireless router 230-a at step 276.
In step 276, the wireless router 230-a may synchronize a local database and forward/broadcast the wireless network information to be switched to the connected plurality of smart home devices 210 in response to receiving the wireless network information to be switched.
At step 278, the smart home device 210 may receive and store the wireless network information to be switched and transmit an indication to the wireless router 230-a that the wireless network information to be switched was successfully received.
In step 280, smart home device 210 enters a switching mode in response to receiving the switching instruction. In this switching mode, smart home device 210 may still be connected to wireless router 230-a.
In step 284, the wireless router 230-a may switch wireless networks after receiving an indication that the reception of the switch wireless network information was successful, which is transmitted by all smart home devices 210 connected thereto. And at step 286, smart home device 210 detects the disconnection of the original connection with wireless router 230-a and uses the stored new wireless network information to access the new wireless network associated with wireless router 230-a.
Therefore, the system of the invention completes batch wireless network switching of the intelligent home equipment in a multi-wireless network environment. By performing the above steps, in the case of modification of the wireless network information, the above switching process (steps 270-286) may be performed instead of performing a special reconfiguration operation, so that the gateway sends the wireless network information of the new network to the corresponding one or more smart home devices, so that the smart home devices can rapidly switch networks in batches.
In yet another aspect of the present application, referring to fig. 2C, similarly to fig. 2A, in an initial state, the gateway has established device associations with different wireless routers (e.g., wireless routers 230-a and 230-B), respectively, forming wireless networks with different wireless network information, e.g., a first wireless network associated with wireless router 230-a, a second wireless network associated with wireless router 230-B, etc. Further, the smart home device 210 has access to the first wireless network.
Further, it should be appreciated that while only one smart home device and two wireless routers are shown in fig. 2C, the present invention is not limited to the smart home devices/wireless routers shown in the figures, but may include more smart home devices/wireless routers.
Initially, the method for automatically synchronizing wireless network information in a multi-wireless network environment described with reference to fig. 2A, wireless network information of available networks is stored in the smart home device 210.
At 280, smart home device 210 may scan wireless signal quality of surrounding covered networks and select an available wireless network with the best wireless network quality based on the wireless network quality and stored wireless network information. For example, the smart home device 210 may periodically scan for signal quality of one or more wireless networks (e.g., including a first wireless network, a second wireless network, etc.) that are covered around it, and may rank the signal quality to determine whether the current network is an optimal network.
At 290, the smart home device automatically switches to the available wireless network with the best wireless network quality when the available wireless network with the best wireless network quality is not the currently connected wireless network. For example, the smart home device 210 may switch networks when the available wireless network having the best wireless network quality is the second wireless network and perform a corresponding access procedure using the previously stored wireless network information of the second wireless network to access the second wireless network.
Therefore, the system of the invention completes the automatic switching of the intelligent home equipment to the optimal wireless network under the multi-wireless router multi-wireless network environment.
Fig. 3 illustrates a block diagram supporting batch and automatic switching to an optimal wireless network apparatus for implementing smart home devices in accordance with an embodiment of the present invention. As shown, the system of the present aspect may include one or more smart home devices 310 (e.g., smart home devices 310-1, 310-n), a gateway 320, a wireless router 330, and a user terminal 340, between which a wireless network connection has been established.
As shown, smart home device 310 may include: a wireless network information synchronization module 316 (e.g., 316-1, 316-n), a wireless network handover implementation module 317 (e.g., 317-1, 317-n), a wireless information storage module 318 (e.g., 318-1, 318-n), and a wireless network quality analysis module 319 (e.g., 319-1, 319-n). Gateway 320/wireless router 330 may include: a wireless network information synchronization module 326 (e.g., 326-1, 326-2), a wireless network handoff execution module 327 (e.g., 327-1, 327-n), a wireless information storage module 328 (e.g., 328-1, 328-2).
As shown, the wireless network handover trigger module 315 may be deployed at the user terminal 340. It should be appreciated that the wireless network handover trigger module 315 may be deployed at the user terminal 340 or at the gateway 320. For simplicity, the following embodiments are illustrated in a user terminal with reference to a wireless network handover triggering module, it being understood that they should not be taken as limiting the present application. The wireless network switch trigger module 315 may receive wireless network information (e.g., SSID and password information) entered by the user and send this wireless network information to the wireless information storage module 328-1 at the gateway 320. The wireless network switch triggering module 315 may also receive network switch information entered by the user and send the network switch information to the network switch execution module 327-1 at the gateway 320.
The wireless network information synchronization module 316 may be deployed on the smart home device 310 side, and may acquire wireless network information (e.g., SSID and password information) that the smart home device 310 is currently connected to, upload to the gateway 320/wireless router 330, and may receive wireless network information used by other smart home devices from the gateway 320/wireless router 330, and send the wireless network information to the wireless information storage module 318 for local storage.
The wireless information storage module 318 may be deployed on the smart home device 310 side to store wireless network information from the wireless network information synchronization module 316 for network selection and connection by the smart home device 310.
The wireless network quality analysis module 319 may be deployed on the smart home device 310 side to scan wireless network information of wireless networks covered around the smart home device 310, output a quality ranking of wireless covered networks centered around the current smart home device 310, and may further select an optimal wireless network based on the ranking and the available wireless network information stored in the wireless information storage module 318, and generate a corresponding handover instruction to send to the wireless network handover implementation module 317.
The wireless network switch implementation module 317 may be disposed on the smart home device 310 side, and may receive a network switch instruction. The network handover command may be a handover command input by the user received by the wireless network handover execution module 327 from the wireless network handover trigger module 315, or may be a handover command from the wireless network quality analysis module 319. Subsequently, the wireless network switch implementation module 317 may parse the received network switch instruction and convert the same into information that can be identified by the smart home device 310 to complete the network switch of the smart home device 310.
Wireless network information synchronization module 326 may be deployed on the gateway 320/wireless router 330 side that receives and forwards wireless network information for one or more connected smart home devices 310. For example, wireless network information synchronization module 326-1 at gateway 320 may receive wireless network information of smart home device 310-1 and forward it to wireless router 330, or may receive wireless network information of smart home device 310-n forwarded by wireless router 330 and forward it to smart home device 310-1. Similarly, wireless network information synchronization module 326-2 at wireless router 330 may receive wireless network information of smart home device 310-n, forward it to gateway 320, and may also receive wireless network information of smart home device 310-1 forwarded by gateway 320, and forward it to smart home device 310-n.
The wireless information storage module 328 may be disposed on the gateway 320/wireless router 330 to store wireless network information from the wireless network information synchronization module 326, as well as wireless network information (e.g., SSID and password information) received by the wireless network switch trigger module 315 from a user.

Fig. 4 illustrates a flow chart of a smart home device side for implementing batch switching according to an embodiment of the present invention.
In combination with the system structure diagram of fig. 3, the wireless network switching triggering module may be deployed at a user terminal or at a gateway. In the application, the gateway and the wireless router can be both provided with a wireless network information synchronization module, a wireless switching execution module and a wireless network storage module. For simplicity, the following embodiments are illustrated with reference to the wireless network handover triggering module in the user terminal, while the wireless network information synchronization module, the wireless handover execution module, the wireless network storage module are deployed in the gateway, it should be understood that they should not be taken as limiting the present application.
The smart home device side flow diagram may begin with the initiation of two sub-flows, the first sub-flow being responsible for wireless network information synchronization and the second sub-flow being responsible for receiving network switch instructions and performing wireless network switches.
In a first sub-process with respect to wireless network information synchronization:
in step 402, the smart home device may send wireless network information (e.g., SSID/password) that it is currently using to a gateway (e.g., a wireless network information synchronization module at the gateway) to inform the gateway of the wireless network information used by the smart home device;
in step 404, the smart home device may receive wireless network information (e.g., SSID/password) sent by the gateway to inform the smart home device of wireless network information being used by other smart home devices;
in step 406, the smart home device may determine whether the received wireless network information needs to be synchronized into a local database of the smart home device. For example, the smart home device may compare its stored wireless network information about what other smart home devices are using with the wireless network information currently being used by other smart home devices, and if the two are consistent, then it is not necessary to synchronize the wireless network information in the local database of the smart home device, and return to step 404, where the smart home device continues to wait to receive the wireless network information sent by the gateway.
If synchronization is required, proceeding to step 408, the smart home device may store the wireless network information that needs to be stored in a local database. For example, the smart home device may store new wireless network information that other smart home devices are using.
In a second sub-flow regarding wireless network information handover:
at step 412, the smart home device may receive and parse the wireless network handover instruction (e.g., the handover instruction received by the wireless quality analysis module or generated by the gateway based on user input in fig. 3).
In step 414, the smart home device may determine whether a currently used wireless network needs to be switched according to the parsed wireless network switching instruction. If the wireless network switch instruction indicates that a switch is not needed, then return to step 412, where the smart home device continues to wait to receive the wireless network switch instruction.
If the wireless network switch instruction indicates that a switch is required, then proceeding to step 416, the smart home device may select an appropriate wireless network and perform a switch operation according to the switch instruction. In the embodiment of the application, the switching instruction indicates that the intelligent home equipment is switched to the network with the best network quality, and the intelligent home equipment can execute the instruction to switch. In another embodiment of the present application, the switching instruction may instruct the smart home device to modify the network password currently used by the smart home device, and the smart home device modifies the wireless network information in its local database and switches to the password-modified network.
Fig. 5 illustrates a flow chart of a gateway side for implementing bulk handover according to an embodiment of the present invention.
The gateway side flow chart starts with starting two sub-flows, the first sub-flow is responsible for wireless network information synchronization, and the second sub-flow is responsible for receiving and forwarding network switching instructions.
In a first sub-process with respect to wireless network information synchronization:
in step 512, the gateway may receive wireless network information (e.g., a password or SSID) of a wireless network transmitted by the at least one smart home device, the wireless network being a wireless network currently being used by the at least one smart home device. In the embodiment of the application, the gateway may receive wireless network information of a wireless network currently used by the smart home device sent by the smart home device and wireless network information of other wireless networks currently used by other smart home devices sent by other smart home devices. It should be understood that the wireless network information may also be forwarded to the gateway via a wireless router to which the smart home device is connected.
In step 514, the gateway may determine whether the local database needs to be updated based on the received wireless network information. In an embodiment of the present application, if the wireless network information is the same as the network information stored in the local database of the gateway, no update is required, and the process returns to step 512 to continue waiting for receiving the wireless network information sent by the at least one smart home device.
If the wireless network information is different from that stored in the gateway's local database, an update is required and the gateway may switch the wireless network information in the new wireless network information storage module, proceeding to step 516.
In step 518, the gateway may send the latest wireless network information to the at least one smart home device, and return to step 512 to continue waiting to receive wireless network information sent by the at least one smart home device. In embodiments of the present application, the gateway may broadcast only the wireless network information determined to be up-to-date to save resources.
In a second sub-flow regarding wireless network handover:
in step 502, the gateway may receive wireless handover information (e.g., a wireless handover request) for the smart home device. The radio handover information may be from the user plane. The user plane may be, for example, APP located on a smart terminal mobile phone, PAD, etc. used by the user, or may be Web where the user connects to the gateway using a computer.
In step 504, the gateway may determine whether the smart home device needs to switch its wireless network based on the wireless switch information. In an embodiment of the present application, the wireless handover information of the user plane may indicate whether the smart home device is to be handed over. If a handoff is not required, the gateway may return to step 502 to continue waiting to receive wireless handoff information for at least one smart home device.
If a handoff is required, then the gateway may send a handoff instruction to the corresponding one or more smart home devices based on the wireless handoff information at step 506, and then return to step 502 to continue waiting to receive wireless handoff information for at least one smart home device. In an embodiment of the present application, if the switching instruction of the user plane indicates that the smart home device is switched from the current network to the new network after the password is modified, the smart home device may execute the instruction to switch.
