Such modifications and variations are intended to be included within the scope of the present application.
Fig. 1 shows an implementation environment schematic diagram of an intelligent home device networking method provided by the embodiment of the present application.
As shown in fig. 1, the implementation environment includes an intelligent device 101, a routing device 102, a gateway device 103, and a control end 104.
The smart device 101 is generally configured with a communication module, in this implementation, operations of the smart device 101 for accessing a network and performing channel scanning are specifically implemented by a network component inside the smart device, for example, by the communication module, and hereinafter, operations of the smart device 101 for performing channel scanning and the like are described, which may also be understood as operations of the network component communication module inside the smart device 101 for performing channel scanning.
In this embodiment, the smart device 101 may be various smart appliances, such as a smart television, a smart refrigerator, a smart air conditioner, and the like.
The intelligent device 101 realizes indirect connection with the gateway device 103 through the routing device 102, acquires network configuration information of the gateway device 103 based on the indirect connection, and connects the gateway device 103 to access a network according to the network configuration information.
The routing device 102 may be a router having a DHCP (Dynamic Host Configuration Protocol) function.
In this embodiment, the routing device implements indirect connection between the intelligent device 101 and the gateway device 103, so that the intelligent device can obtain the network configuration information of the gateway device 103 based on the indirect connection.
In some embodiments, the wireless connection of the smart device to the routing device and the wired connection of the routing device to the gateway device via which the smart device may be indirectly connected. The intelligent equipment can receive the configuration message sent by the gateway equipment through the indirect connection, so that the intelligent home equipment can establish direct connection with the gateway equipment according to the network configuration information of the gateway equipment carried in the configuration message, and networking of the intelligent home equipment is realized.
The gateway device 103 is a gateway for network access, which integrates the functions of a router for establishing a local area network. The gateway device 103 realizes indirect connection with the intelligent device 101 through the routing device 102, and sends network configuration information of the gateway device 103 to the intelligent device 101 based on the indirect connection, so that the intelligent device can access a local area network established by the gateway device 103 according to the network configuration information, thereby realizing networking.
The control end 104 accesses the wireless local area network by performing zero configuration on the intelligent device 101. The control terminal may be a PC terminal and applications, a modern mobile transceiver, which may correspond to a smartphone, a cellular phone, a user equipment, a radio, a mobile phone, a mobile station, a laptop, a notebook, a Personal Digital Assistant (PDA), a Universal Serial Bus (USB) -stick, etc. mobile device, which may support multi-technology multi-band networks because it is typically equipped with multiple LTE, HSPA, WiFi transceivers operating in multiple licensed and unlicensed frequency bands.
The zero configuration is also called wireless automatic configuration, and refers to a process of configuring information of a to-be-accessed routing device to a communication module of the intelligent device 101, which is not configured with the information of the routing device, in a wireless manner.
The zero configuration selects a wireless network to be connected according to the preference dynamic of a user and various default settings, and can be used for replacing a wireless network utility program provided by a computer wireless network equipment manufacturer or not using the wireless network utility program, so that the intelligent home equipment can search a channel for a service which is preset and matched with a network name SSID and is automatically connected. In the zero configuration process, if the communication module of the smart home device cannot be connected to the preferred wireless network through the WIFI network, the bluetooth connection mode is started to acquire the network configuration information of the router through the bluetooth communication connection of the control terminal 104, and then the router is automatically connected to the network; and when the Bluetooth connection cannot be accessed to the network in time, the communication module can start the network distribution network in the SoftAP mode to access the network.
Fig. 2 is a schematic diagram illustrating general steps of a zero configuration access network of an intelligent device according to an embodiment of the present application.
When the smart device 101 needs to access the WIFI local area network, the user performs zero configuration on the smart device 101 through the control terminal 104, which generally includes the following steps:
in step 201, the intelligent device 101 receives an original information set of the to-be-accessed routing device 102 sent by the control end 104, where the original information set includes distribution network information such as an SSID of the routing device 102, a password, and a mac address of the routing device, that is, a BSSID.
In some embodiments, the original information groups may be further combined into overall data by the control end 104, so as to increase the transmission rate of the overall data sent by the control end.
It should be noted that the routing device described in this embodiment of the present application may also be other network devices with network access, and in this embodiment, for convenience of describing an access method of an intelligent device, a routing device is taken as an example for description.
In step 202, the intelligent device 101 accesses the routing device 102 according to the distribution network information of the original information group of the routing device 102.
It should be understood that while operations are depicted in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In some cases, multitasking or parallel processing may be beneficial.
The zero configuration of the access network to the intelligent device 101 through the control terminal 104 includes three modes: the network is distributed in a discrete mode, a network is distributed in a SoftAP mode, and a network is distributed in a Bluetooth mode.
The distribution network in the discrete mode refers to that the intelligent device 101 performs wireless network configuration access through a UDP protocol, and UDP is a method for sending encapsulated IP datagrams without establishing a connection. UDP is a connectionless protocol in that the source and the terminal do not establish a connection before transmitting data, and simply grab the data from the application when it wants to transmit and throw it as quickly as possible onto the network.
At the sending end, the speed of data transmission by UDP is limited only by the speed of data generation by the application program, the capability of the computer and the transmission bandwidth; at the receiving end, UDP places each message segment in a queue, from which the application reads one message segment at a time. Since the UDP transmission data does not establish a connection, it is not necessary to maintain connection states, including a transceiving state, and the like, and therefore the routing device 102 can transmit the same message to multiple intelligent devices 101 at the same time. The header of the UDP packet is very short, only 8 bytes, and the additional overhead of UDP is very small compared to the 20-byte packet of TCP. UDP is an ideal Protocol suitable for distributing Information and can be used to modify Routing tables in RIP (Routing Information Protocol). In these applications, if a message is lost, it is replaced by another new message a few seconds later.
The distribution network in the SoftAP mode refers to configuration by setting the smart device 101 as a hotspot. The method comprises the steps that a wireless chip of the intelligent device 101 is used for enabling the device to enter a softAP mode, a wireless local area network is started, the control terminal 104, namely a mobile phone or other mobile devices, sends information such as SSID (service set identifier) and Psswing of a router to the device after being connected to the wireless local area network started by the intelligent device, and the device obtains the SSID information of the router under the condition of no screen, so that the purpose of networking is achieved.
The process of the network distribution of the SoftAP is complex, the control end 104 needs to disconnect from the original router first, then the intelligent device 101 opens the SoftAP mode, the control end 104 accesses the SoftAP and sends the ssid and the password of the router to the intelligent device 101, then the SoftAP mode is closed again, the intelligent device 101 returns to the normal station mode, then the intelligent device 101 connects with the router according to the router information, and the mobile phone reconnects with the router according to the situation. The softAp mode distribution network has the characteristics of complex flow and high stability.
The bluetooth mode network distribution means that the intelligent device 101 is directly connected to the control terminal in a bluetooth mode to obtain network configuration data, so that the intelligent device 101 is accessed to the network.
The following will describe the detailed steps of the above-mentioned zero-configuration access network mode of various intelligent devices and the mode of the intelligent devices accessing the network.
Fig. 3 shows a schematic flow diagram of a distribution network of a smart device in a discrete mode according to an embodiment of the present application.
In some embodiments, the steps of the smart device 101 configuring the network through the discrete mode are as follows:
in step 301, the control end 104 accesses the routing device 102 and listens for access information of the smart device 101.
In step 302, the smart device 101 starts the discrete mode, and listens for and waits for receiving the original information group of the routing device 102 sent by the control end 104 at any time.
When the smart device 101 accesses a wireless local area network configured by a routing device, there are generally two situations.
When the intelligent device 101 never stores the distribution network information of the routing device 102, the distribution network information is the original information group or the access information, the intelligent device 101 will actively enter the discrete mode after being started, and monitor and receive the configuration data of the routing device sent by the control end 104 in the channel at any time for network connection.
When the access information of the routing device 102 is stored before the intelligent device 101 accesses the network, the intelligent device 101 can directly perform network connection according to the stored distribution network information of the routing device 102 after being started, so that the purpose of fast network access is achieved.
It should be noted that in some embodiments, the smart device 101 may also be configured to actively turn on the discrete-mode distribution network by the user. For example, a physical button for the smart device 101 to start the discrete mode distribution network is set, or the smart device 101 receives a key value or a signal sent by a control device for controlling the smart device 101 to start the discrete mode distribution network function of the smart device 101. For example, the user may press a physical button of the smart device 101 for a long time or trigger the discrete-mode distribution network through a remote control button of the smart device 101.
In step 303, the control end 104 starts configuration to send the original information set of the routing device 102, that is, configuration information to the local area network circularly until the distribution of the intelligent device 101 is finished.
The control end 104 starts configuration and sends the original information group containing the routing device 102, that is, the whole data of the configuration information to the local area network circularly until the intelligent device 101 is connected to the network distribution network. In some embodiments, the distribution network information is combined overall data.
First, the control end 104 obtains the original information group of the routing device 102 from the local area network where the control end is located. In some embodiments, the control end 104 further combines the original information into a group to obtain overall data, so as to improve the sending rate of the data.
Secondly, the control end 104 sends the original information group in a cycle in the local area network, and when the intelligent device 101 monitors and receives the original information group in the channel, the hot spot information in the channel is compared with data information such as SSID, password, mac, and the like of the routing device 102 related to the message information in the original information group, so as to determine a target hot spot to be accessed in the numerous hot spots in the channel, which may also be called a target routing device 102 or a target WIFI local area network, and when the intelligent device 101 successfully accesses the target routing device 102, the network is successfully distributed.
Finally, after the distribution network is successful, the control end 104 also receives the message notification that the intelligent device 101 successfully accesses the network, thereby ending the distribution network process of the intelligent device 101 and the control end.
It should be understood that while operations are depicted in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In some cases, multitasking or parallel processing may be beneficial.
Fig. 4 shows a flowchart of a network distribution in the SoftAP mode of an intelligent device in an embodiment of the present application.
In some embodiments, the process of the smart device 101 configuring the network via the SoftAP mode is as follows:
in step 401, the control end 104 first accesses the wireless local area network set by the routing device 102. The wireless local area network configured by the routing device 102 is also referred to as a hotspot configured by the routing device 102 or a local area network or hotspot constructed by the routing device 102.
The specific scene of the wireless local area network can be a wireless local area network set by a router in a family, and can also be a wireless local area network in other application scenes.
In step 402, the smart device 101 starts the SoftAP mode, and establishes an SSID hotspot at the beginning of the specific field, that is, the wireless local area network waits for the access of the control end 104.
In this embodiment, the SSID hotspot at the beginning of the specific field may also be interpreted as a preset SSID hotspot with a certain rule or a wireless lan, where the specific rule may be preset by a different manufacturer or set by a user. In this embodiment, the SSID hotspot beginning with the specific field may be set to, for example, the SSID hotspot beginning with "HIS-".
In step 403, the control end 104 acquires the original information group network information of the routing device 102 in the local area network. In some embodiments, the control end 104 further combines the original information groups to obtain overall data to increase the transmission rate of the data packet.
In step 404, the control end 104 scans the SSID hotspot at the beginning of the specific field established by the intelligent device 101 in step 402 again in the channel, and accesses and sends the zero configuration instruction including the original information group to the intelligent device 101.
It should be noted that, since the control end 104 is usually a mobile communication device, such as a mobile phone, and the control end has a professional communication chip, an antenna, and a processor for radio communication, the connection rate and the reliability of the control end 104 are higher in the process of establishing the wireless local area network or transceiving the data packet by the scanning and routing device 102, and therefore, the success rate and the reliability of the network distribution through the SoftAP mode are also higher.
In step 405, the intelligent device 101 receives the zero configuration instruction including the original information group and returns a result instruction of receiving confirmation to the control end, and the intelligent device 101 starts to access the wireless local area network set by the routing device 102 according to the zero configuration instruction including the original information group after waiting for a preset time interval.
In the present embodiment, the preset time interval is set to 200 ms, so as to keep synchronization with the feedback result of the control end 104. It should be noted that, the specific value of the preset time interval is not limited in the present application, and only needs to be configured according to the actual time requirement of the required distribution network.
In step 406, after receiving the result instruction of the reception acknowledgement sent by the intelligent device 101, the control end 104 accesses the wireless local area network set by the routing device 102 again; the intelligent device 101 accesses the wireless local area network set by the routing device 102 according to the zero configuration instruction containing the original information group.
In step 407, the control end 104 searches for access information of the intelligent device 101 in the wireless local area network constructed by the routing device 102, the intelligent device 101 successfully accesses the network, and the distribution network process is ended.
It should be understood that while operations are depicted in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In some cases, multitasking or parallel processing may be beneficial.
Fig. 5 shows a schematic flow diagram of a network distribution in a bluetooth mode of an intelligent device in an embodiment of the present application.
In some embodiments, the process of the smart device 101 going through the bluetooth mode network is as follows:
in step 501, the control end 104 connects to the smart device 101 through bluetooth connection and performs authentication.
In step 502, the control end 104 sends the original information group of the routing device 102, that is, the distribution network information, to the smart device 101 through bluetooth connection.
The distribution network information is obtained by encrypting an original information group configured by the routing device 102 through a public key by the control end 104 and then sending the encrypted original information group to the intelligent device 101 through a Bluetooth connection, wherein the public key is public and does not need to be kept secret.
In step 503, the intelligent device 101 obtains an original information group by decrypting the encrypted network configuration information sent by the control end 104 with a private key, and connects to the wireless local area network set by the routing device 102 according to the data information of the original information group.
The private key is held by the intelligent device and is generally generated locally, and in particular, in use, a signature operation is performed, a sender signs with the private key, and a receiver verifies the signature with a sender certificate. The encryption operation is carried out by using the certificate of the receiver, and the receiver carries out decryption by using the private key of the receiver.
It should be understood that while operations are depicted in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In some cases, multitasking or parallel processing may be beneficial.
Fig. 6 shows a flowchart of a method for accessing a network by an intelligent device based on bluetooth and a wireless network according to an embodiment of the present application.
In some embodiments, the method for the smart device 101 to access the network based on the bluetooth and wireless network hybrid mode is as follows:
in step 601, the smart device 101 simultaneously starts a bluetooth mode distribution network, a discrete mode distribution network, and a SoftAP mode distribution network.
The intelligent device 101 monitors the access of the control end 104 through bluetooth connection.
Meanwhile, the distribution network intelligent device 101 based on the SoftAP mode also establishes an SSID hotspot at the beginning of a specific field for monitoring the access of the control end 104. The intelligent device 101 creates an SSID hotspot according to a certain rule, and the control end 104 can search for the SSID hotspot with the predetermined rule in a channel according to the predetermined rule, so as to achieve the purpose of accessing the network quickly.
It should be noted that the distribution network with the 3 modes is controlled by the intelligent device 101 to be simultaneously opened, but actually, due to the influence of processing speeds of a control chip, a memory and the like, the opening speeds of the distribution network with the 3 modes are slightly different, and in this embodiment, the time difference of the opening of the distribution network with the 3 modes is ignored.
In step 602, the intelligent device 101 scans the routing device information of the spatial channel where it is located, and stores the BSSID and channel information of the routing device found by scanning, typically starting from the first channel.
It should be noted that, based on the intelligent device 101 accessing the network quickly, in this embodiment, the intelligent device 101 stores the scanned routing device information in the scanning process, where the information includes an SSID, a BSSID, a channel number of the routing device, and the like.
In some scenarios, the smart device 101 may search for multiple routing devices in the channel, and the multiple routing devices may sometimes set the same hotspot name, that is, the SSID information is the same, and the SSID may be considered to be a string character in nature.
Based on such a scenario, the intelligent device 101 in this embodiment additionally stores BSSID information of the routing device, i.e., mac address of the routing device. Because the mac address is unique, according to the BSSID information and the channel number of the routing device, the routing device in the channel can be calibrated quickly, support is provided for operations such as subsequent channel scanning switching and access of the routing device, and the speed of the intelligent device 101 for distributing the network is improved.
In step 603, the smart device 101 detects and receives the data packet by switching different channels.
First, the smart device 101 scans for wireless hotspots existing in the space. The smart device 101 typically starts scanning from channel 1 if it has a wireless hotspot to connect to.
Secondly, if the current channel detects that a hot spot exists, the smart device 101 stays in the current channel for more time to receive configuration information of routing devices that may exist in the current channel, where the number of the routing devices that may exist may be 1 or multiple.
It should be noted that the total scanning time of the smart device 101 in the current channel and 2 adjacent channels suspected of having the target hotspot may be set according to actual situations, and in this embodiment, the scanning time of the 3 channels is set to be not more than 1 second. The network can be distributed in a Bluetooth mode and a SoftAP mode in a matching mode, and the problem of serious delay of network connection in a single mode is avoided. In this embodiment, the above-mentioned switching of 13 channels may be scanned in the order of their channel numbers.
It should be noted that, in some embodiments, the intelligent device 101 scans 13 channels, and switching the channel scanning may also preferentially scan channels with hot spots, and sort the channel scanning without data packets to the end.
It should be noted that, in order to increase the speed of accessing the network by the smart device 101 and combine multiple modes for network distribution, for example, a network distribution mode combining the bluetooth mode, the discrete mode, and the SoftAP mode described in this embodiment of the present application, to avoid a long-time network connection in a single mode, in this embodiment, the maximum scanning time parameter is set in step 603. When the intelligent device 101 detects that the suspected hot spot exists in the current channel, the scanning time of the current channel is set as the maximum scanning time parameter, and if the suspected hot spot does not exist in the current channel, the scanning time of the current channel is set to be shorter, so that the advantage of the multi-mode distribution network of the intelligent device 101 can be exerted.
In step 604, the intelligent device 101 detects whether distribution network information sent from the control end 104 is received, where the distribution network information is an original information group of the routing device 102.
If the intelligent device 101 receives the original information group sent from the control end 104, step 605 is executed;
if the intelligent device 101 does not receive the original information group sent by the control end 104, detecting whether the intelligent device 101 receives the original information group sent by the control end 104 through bluetooth;
if the smart device 101 has received the distribution network information through bluetooth, execute step 607;
if the smart device 101 cannot receive the distribution network information, step 603 is executed to switch to the next channel.
In the process of the hybrid mode network distribution, the routing device 102 and the control end 104 which need to be accessed are in the same wireless local area network, and can also be considered to be in the same channel. If the intelligent device 101 detects that the hot spot information of the target routing device 102 is received in the current channel, the original information group sent by the control end 104 may also be detected.
In step 605, if BSSID information of the original information group packet matches a hotspot obtained by scanning a current channel, the communication device sets the current channel as a fixed scanning channel;
if the BSSID information of the original information group packet does not match the hotspot scanned by the current channel, the intelligent device 101 switches the scanning channel to the current channel and 2 channels adjacent to the current channel;
the intelligent device 101 detects some data packets sent by the suspected routing device from the current channel, where the data packets may include configuration information of the suspected routing device, such as BSSID, SSID, and other information. Then, the intelligent device 101 compares the configuration information of the suspected routing device with the original information group, so as to determine whether a suspected hotspot or suspected routing device existing in the current channel is the routing device 102.
It should be noted that when the communication module of the current channel detects a packet with a predetermined rule attached thereto, but cannot perform subsequent connection, or when subsequent packet detection is extremely difficult, the smart device 101 may further perform packet detection on 2 adjacent channels of the current channel. Since the adjacent channels may generate interference in actual hot spot data transmission, that is, the current channel may possibly receive a data packet transmitted by the hot spot of the adjacent channel, when the current channel cannot further receive a data packet having a predetermined rule or cannot further connect to the target routing device 102, the smart device 101 may preferentially scan 2 adjacent channels of the current channel, and set the scanning time thereof as the maximum scanning time.
The smart device 101 receives a data packet in the current channel with a predetermined rule attached, which may be considered to be the SSID at the beginning of the specific field mentioned above. Further, it may be considered that there is a routing device 102 that needs to be accessed in the current channel, the intelligent device 101 may further analyze information such as a mac address of the routing device from the received data packet to which the predetermined rule is appended, the rule or the foregoing rule is that the control end 104 circularly sends an original information group containing configuration information of the routing device 102 to the local area network for comparison, if a suspected hotspot of the current channel is determined to be a hotspot set by the routing device 102 that the intelligent device 101 needs to access, the intelligent device 101 fixes the scanning channel thereof to the current channel, and further receives the data packet for network access.
In step 606, if the valid packet from the routing device 102 of the fixed scanning channel is received within the preset maximum packet receiving time, the intelligent device 101 starts to access the wireless local area network set by the routing device 102 according to the original information group and the valid packet;
if the intelligent device 101 cannot receive the valid message within the maximum message receiving time, the intelligent device 101 executes step 603 again to switch to the next channel.
In this embodiment, the preset maximum message receiving time is set to 1 second. It should be noted that, the specific value of the preset maximum message receiving time is not limited, and the configuration may be performed according to the actual time requirement of the required distribution network.
In some embodiments of the present invention, the smart device 101 compares the SSID (i.e., the network name of the local area network), the encryption method, and the password of the original information group packet. After the verification is passed, the intelligent device establishes a direct wireless network connection with the routing device 102, so that the intelligent device can access a local area network, thereby realizing networking.
In step 607, it is checked whether the access to the network is successful within the preset maximum connection time,
if the intelligent device 101 has accessed the network, the distribution network finishes the ending process;
if the intelligent device 101 does not access the network within the maximum connection time, the intelligent device 101 closes the discrete mode distribution network, continues the SoftAP mode distribution network, and executes steps 403 to 407 in this embodiment.
When the intelligent device 101 successfully accesses the wireless local area network set by the routing device 102, the routing device sends information of the online of the intelligent device 101 to the control terminal 104, so that a user can timely know the distribution network state of the intelligent device 101.
The intelligent device 101 detects whether the network access is successful within the preset maximum connection time, so as to judge whether the network distribution in the SoftAP mode needs to be started. In this embodiment, the preset maximum connection time is set to 1 minute. It should be noted that, the present application does not limit the value of the preset maximum connection time, and the configuration may be performed according to the actual time requirement of the required distribution network.
It should be noted that, the smart device 101 may also consider that the control end 104 actively initiates after the maximum connection time when starting the SoftAP mode distribution network. At the smart device 101, in step 601, the SoftAP mode distribution network has been started in advance, and the communication module of the smart device is always in the monitoring state of the SoftAP mode distribution network.

In step 702, the control end 104 connects to the smart device 101 through bluetooth, and sends the original information group of the routing device 102 to the smart device 101.
In step 703, the control end 104 sends the original information group of the routing device 102 in a multicast manner through the wireless local area network set by the routing device 102, for receiving by the intelligent device 101.
In step 704, the control end 104 detects whether the access network information of the intelligent device 101 is received,
if so, the intelligent device 101 is successfully accessed to the network, and the distribution network process is finished;
if the SSID hotspot network access is not received and the intelligent device 101 does not access the network within the preset maximum connection time, the control end 104 searches for the SSID hotspot network access at the beginning of the specific field established by the intelligent device 101 and sends the original information group of the routing device 102 to the SSID hotspot network access.
It should be understood that while operations are depicted in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results.
