Technical Field

The present application relates to a method for communication between devices, and in particular, to a method and an apparatus for communication between network devices. Also relates to a method and a device for communicating with the network equipment and a method and a device for communicating with the network equipment.

Background

With the popularization of network deployment, more and more functions realized by using a network are applied to various fields, and meanwhile, as the application of network technology is more and more extensive, more and more devices have the function of communicating with other devices or applications through the network.

Since the currently available networks include both local area networks and wide area networks such as the internet, compared to the conventional mode of directly communicating with the target device through the console or data line of the target device, although the existing functions of communicating with the target device through the network provide more ways to communicate with the target device than the conventional manner, they are based on being fixed to a certain network.

The advantage of wide coverage of the internet and telecommunication networks can be fully utilized by communicating with the target device through the internet, but due to the complex and variable structure of the internet, message delay is inevitable and difficult to guarantee within an acceptable range. This will undoubtedly lead to misjudgment or even failure of the communication.

The timeliness and the high efficiency of the message can be more easily ensured by communicating with the target device through the local area network. But the application range is limited within the range of the local area network due to the limitation of the coverage range.

When a device needs to communicate with other devices or applications, it is typically only able to communicate over the network to which the device is currently connected, and not selectively with the appropriate network. It can be seen that the existing method for communicating with the target device through the network does not coordinate and use different networks according to the characteristics of different networks, and the timeliness and efficiency of communication between devices cannot be well guaranteed.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.

A first embodiment of the present application provides a method for communication between network devices, a flowchart of which is shown in fig. 1, and the embodiment includes the following steps:

step S101, a request for communication with a specified target device is obtained, the specified target device being determined by a device identification.

This step is a start-up step of communication with the target device; initiating a communication process requires at least two elements: a communication start instruction, a designated communication object; these two elements are obtained in different ways in different execution devices and communication applications. Wherein, the communication object, namely the target device, is determined by using the device identifier of the target device. The device identifier of the target device may include, for example, a MAC address of a network card of the smart device, a device name, or a serial number of the device, so that different types of device identifiers may be flexibly used according to different situations. A request to communicate with a specified target device is a set of instructions that contain the two basic communication elements described above.

To better explain the embodiment, the smart watch is taken as the execution device of the method, and the specific process of the step is illustrated by taking the remote control communication between an Application (APP) of the smart watch and the smart home device (such as the smart air conditioner) as an example.

The method comprises the steps that an intelligent watch receives a click signal for carrying out certain control on a certain intelligent air conditioner in APP (application) of intelligent air conditioner remote control, and then the click signal is used as a basis for starting communication to send a communication starting instruction; meanwhile, the equipment identification of the intelligent air conditioning equipment to be controlled is obtained from the pre-stored information and is used as a basis for determining a communication object.

The following is an example of a specific communication process of the smart watch and the smart air conditioner.

The intelligent watch receives operation of a user on the APP application of the intelligent air conditioner remote control, and receives an instruction of requiring adjustment of the set temperature of the air conditioner through click operation of the touch screen.

The APP immediately sends out a communication starting instruction, and a series of processes for establishing communication are started, wherein the processes comprise obtaining and storing the equipment identification of the intelligent air conditioner. The purpose of the communication is to transmit the command for adjusting the set temperature of the air conditioner, which is the communication content, and the communication content can be transmitted only after the communication between the smart watch and the smart air conditioner is established.

When the smart watch needs to communicate with the smart air conditioner, the obtained request for communicating with the smart air conditioner simultaneously contains the equipment identifier of the smart air conditioner, the equipment identifier is generally stored in the smart watch, if the equipment identifier is not stored, the operation of mutually establishing a recognition relationship between the smart watch and the smart air conditioner may be required to be performed, of course, the relevant recognition may also be performed while the communication request is sent, and in this case, a step of selecting a communication object by an operator of the smart watch is required to be added.

The device identifier of the intelligent air conditioner may include, for example, the MAC address of the network card of the intelligent air conditioner, the name of the intelligent air conditioner, or the serial number of the intelligent air conditioner, so that different types of device identifiers may be flexibly used according to respective actual conditions of different applications.

Step S102, judging whether the local area network is connected currently.

Whether the local area network is connected can be judged according to whether the current equipment obtains the effective local area network IP address. The address of the local area network is usually defined by the relevant specification, and the device obtains an IP address that conforms to the IP address range of the local area network defined by the relevant specification, which can be considered as a device that is already connected to the local area network, otherwise, as a device that is not connected to the local area network. The use case of the allocation of the specific IP address can refer to the relevant specification definition, such as specification RFC1918 of IPv4 or specification RFC4193 of IPv6, which is usually followed by local area network address planning. In case of deviation from the above or related specifications, the judgment can be made according to the actual situation of the network.

The local area network is not limited to a wired network (LAN), but may also be a Wireless Local Area Network (WLAN), and further includes a Virtual Local Area Network (VLAN), etc., and devices connected to these networks are all located in close proximity to each other physically, so as to guarantee timeliness of communication.

In the previous step, the smart watch is taken as an example, the IP address obtained by the smart watch can be checked, and if the smart watch does not obtain a valid IP address currently, it can be judged that the smart watch is not connected to the local area network; or the current IP Address obtained by the smart watch is not a Local area network Address, and if the current IP Address obtained by the smart watch is a public Address of a wide area network, or the current IP Address obtained by the smart watch is a Link-Local Address (Link-Local Address)169.254.

Step S103, if the local area network is not connected, connecting to a connectable local area network and returning to the step of judging whether the local area network is connected currently.

In the case where no local area network is currently connected, a connectable local area network, such as a Wireless Local Area Network (WLAN), is first connected.

The Wireless Local Area Network (WLAN) comprises a detectable wireless local area network and a Wireless Local Area Network (WLAN) which is pre-assigned with a Service Set Identifier (SSID), namely comprises a Wireless Local Area Network (WLAN) which broadcasts the Service Set Identifier (SSID) and a Wireless Local Area Network (WLAN) which is pre-assigned with the Service Set Identifier (SSID), so that the wireless local area networks which are searched for as many as possible can be searched even for the wireless local area network which does not broadcast the Service Set Identifier (SSID) as long as the Service Set Identifier (SSID) of the wireless local area network is pre-assigned.

After connecting to a local area network, the process returns to step S102 to determine whether the local area network is currently connected.

Still taking a smart watch as an example, it generally has a function of connecting to a wireless local area network as a portable device, and if the smart watch is not currently connected to any local area network, the smart watch is connected to a connectable wireless local area network identified by a Service Set Identifier (SSID) by using the function of connecting to the wireless local area network. The connectable local area network refers to a wireless local area network of which the smart watch is pre-configured with relevant parameters including Service Set Identification (SSID) or a wireless local area network capable of detecting the Service Set Identification (SSID) currently.

After the smart watch is connected to the local area network, the step S102 is returned to, and whether the smart watch is currently connected to the local area network is determined again.

And step S104, if the current connection is to the local area network, judging whether the specified target equipment exists in the current connected local area network.

For the situation of the current connection to the local area network, there are various specific ways to determine whether the specified target device exists in the current connected local area network, and the specific ways may be determined by sending a request message to the network according to the actual situations of the network and the device by using different network protocols. For example: and determining whether the specified target equipment exists in the local area network connected currently by utilizing Address Resolution Protocol (ARP) and Internet Control Message Protocol (ICMP) inquiry.

In addition, it is also possible to determine whether the specified target device exists in the local area network to which the device identifier (such as a serial number) of the device connected in the current network is acquired or the device that requests the device identifier as the device identifier of the specified target device responds to the corresponding request by using other network protocols or by comprehensively using various network protocols. Therefore, different equipment identifiers can be flexibly selected and used according to different actual application conditions.

Taking the example that the smart watch currently connected to the lan judges whether the smart air conditioner exists in the lan currently connected to the lan:

for the condition that the device identifier of the intelligent air conditioner is the Media Access Control (MAC) address of the intelligent air conditioner, an Address Resolution Protocol (ARP) request message can be sent to the currently connected local area network, the intelligent home devices connected with the IP address in the currently connected local area network are requested to feed back the Media Access Control (MAC) addresses one by one, and if the Media Access Control (MAC) address returned in the response message received by the intelligent watch is the same as the specified Media Access Control (MAC) address of the intelligent air conditioner, the intelligent air conditioner with the device identifier as the Media Access Control (MAC) address in the currently connected local area network is judged to exist. And if the response message containing the Media Access Control (MAC) address of the designated intelligent air conditioner is not received, judging that the designated intelligent air conditioner does not exist in the local area network connected currently.

Similarly, for the local area network of IPv6, a Neighbor discovery protocol (Neighbor discovery protocol) may be used to determine whether the specified target device exists in the local area network to which the current connection is made.

For the condition that the equipment identifier of the intelligent air conditioner is the name of the equipment identifier, the Internet Control Message Protocol (ICMP) can be utilized, the host name is set as the name of the specified intelligent air conditioner, an Internet Control Message Protocol (ICMP) message is sent to the local area network connected to the current local area network, and if a corresponding response message is received, the specified intelligent air conditioner can be judged to exist in the current network. Otherwise, judging that the designated intelligent air conditioner does not exist in the current network.

And step S105, if the current local area network exists, communicating with the specified target device through the current connected local area network.

And if the specified target device exists in the currently connected local area network, communicating with the specified target device through the currently connected local area network.

Taking the example that the smart watch has the smart air conditioner to be communicated in the local area network to which the smart watch is currently connected, the smart watch can communicate with the smart air conditioner through the local area network to which the smart watch is currently connected.

For example, the smart watch may send an instruction to the smart air conditioner through the currently connected lan, and perform corresponding control on the operation of the smart air conditioner, such as changing an operation mode, modifying an operation parameter, and the like, or the smart watch may receive and obtain an operation state or some parameters of the smart air conditioner through the currently connected lan, such as the current operation mode, a set temperature index, and the like, so as to facilitate the use of a related application program.

Step S106, if not, judging whether the search of all the connectable local area networks is finished.

In the case that the designated target device does not exist in the currently connected local area network, it is necessary to determine whether the search for all currently connectable local area networks has been completed. For wireless local area networks, all currently connectable local area networks include all currently detectable Service Set Identifications (SSIDs) and wireless local area networks that are not detectable but are pre-assigned Service Set Identifications (SSIDs).

Taking the smart watch with the function of connecting the wireless local area network as an example, if the smart watch does not find the smart air conditioner to be communicated with the smart watch in the currently connected local area network, whether the search of all the wireless local area networks to which the smart watch can be currently connected is finished is judged. For the case that the currently connectable local area networks are only wireless local area networks, all currently connectable local area networks of the smart watch include a first wireless local area network and a second wireless local area network which can be detected, and a third wireless local area network which cannot be detected but is pre-assigned with a Service Set Identifier (SSID), it is necessary to determine whether the assigned smart air conditioner has been found in all of the three local area networks.

Step S107, if the search of all the connectable local area networks is not completed, disconnecting the currently connected local area network and connecting to a connectable local area network which has not been searched, and returning to the step of judging whether the specified target device exists in the currently connected local area network.

And for the condition that the local area network of the target device is not searched, disconnecting the currently connected local area network, connecting the currently connected local area network to the local area network which is not searched, and returning to the step S104 of judging whether the specified target device exists in the currently connected local area network.

In the case that there is no local area network for which the target device has not been searched, since communication with the target device through the local area network is currently not feasible, in order to ensure availability of communication, the currently connected local area network may be disconnected, and then connected to the internet to communicate with the target device.

Therefore, the situation that the designated target equipment cannot be controlled or data can not be obtained due to the fact that the designated target equipment cannot be communicated through the local area network is avoided, the designated target equipment can be communicated through the Internet with large network delay and low timeliness, the designated target equipment can be controlled or the data can be obtained, and the function of guaranteeing the communication availability is achieved.

Still taking the smart watch with the function of connecting the wireless local area network as an example, if the smart watch is currently connected to the first wireless local area network, and the first wireless local area network does not have the smart air conditioner to communicate with, but the second wireless local area network and the third wireless local area network have not been searched, the first wireless local area network connected to the smart watch is disconnected, one wireless local area network is selected from the second wireless local area network and the third wireless local area network, for example, the second wireless local area network is connected to the second wireless local area network, and the step S104 is returned to determine whether the smart air conditioner exists in the currently connected local area network.

If the current search of all the connectable wireless local area networks of the intelligent watch is finished, namely the search of the first wireless local area network, the second wireless local area network and the third wireless local area network is finished, and no intelligent air conditioner to be communicated with the three networks is found in the three networks, the wireless local area network to which the intelligent watch is currently connected is disconnected, if the intelligent watch has the function of connecting to the wireless local area network and the function of accessing to the Internet through a telecommunication network, the intelligent watch is connected to the Internet and is communicated with the intelligent air conditioner through the Internet. The intelligent air conditioner is controlled or corresponding data is received and obtained from the intelligent air conditioner.

The method provided by the embodiment is preferably applied to the smart watch to control the smart home devices including the smart air conditioner, and can also be applied to any control device to control any smart home device including the smart air conditioner.

By adopting the method provided by the embodiment, all local area networks which can be connected can be searched, the local area networks are preferentially utilized to communicate with the target equipment, and the timeliness of communication is ensured.

A second embodiment of the present application provides a method for network device communication, taking a situation that a communication connection has been established between devices as an example, a flowchart of which is shown in fig. 2, and includes the following steps:

step S201, a request for communication with a specified target device, which is determined by the device identifier, is acquired.

The request for communicating with the target device is usually generated by user operation or application program call, and in order to complete corresponding device functions, such as controlling the functions of the target device, for example, operating mode or receiving parameters from the target device, it is necessary to establish a communication connection with the target device, send commands and messages, receive data, and perform communication.

In this embodiment, the communication between the smart watch and the smart home device, such as the smart air conditioner, is still taken as an example, that is, the specified target device is the smart air conditioner, the smart watch obtains the control requirements for the smart air conditioner from the operation of the user, such as changing the working mode or modifying the working parameters, and these requirements need to be sent to the smart air conditioner through an instruction, that is, the smart watch obtains the request for communicating with the smart air conditioner. If the smart watch needs to receive and obtain the working state or some parameters of the smart air conditioner, such as the current working mode, the set temperature and other indexes, the smart watch also needs to be in communication with the smart air conditioner, and at this time, the smart watch can obtain a communication request with the corresponding smart air conditioner from the corresponding program.

When the intelligent watch needs to communicate with the intelligent air conditioner, the obtained request for communicating with the intelligent air conditioner comprises an equipment identifier of the intelligent air conditioner, and the equipment identifier of the intelligent air conditioner can comprise conditions such as an MAC (media access control) address of a network card of the intelligent air conditioner, the name of the intelligent air conditioner or serial numbers of the intelligent air conditioner, so that different equipment identifiers can be flexibly adopted according to respective actual conditions of different applications.

Step S202, establishing connection with the specified target device through the Internet.

Many devices that need to communicate with each other via a network have a function of accessing the internet. The most common way to access the internet is to access the internet through data service functions provided by a telecommunications network. Due to the wide coverage of the telecommunication network, the internet accessed through the telecommunication network can realize the communication between the devices in most cases. The target device typically maintains access to the internet for control of the device. Thus, when the user wants to communicate with the mobile terminal, the user can firstly connect to the Internet and establish communication connection with the mobile terminal through the Internet.

The smart watch and the smart air conditioner in the embodiment can be accessed to the internet through a telecommunication network. The intelligent air conditioner is accessed to the Internet, and after the intelligent watch acquires a request for communication with the intelligent air conditioner, the intelligent watch is accessed to the Internet through a telecommunication network and establishes communication connection with the intelligent air conditioner.

Step S203, ask for the list of local area networks that the designated target device can currently connect to.

After establishing a communication connection with the target device via the internet, instructions may be sent to and information exchanged with the target device via the connected internet. In this step, an instruction is sent to the target device, where the instruction includes a request for requesting a list of local area networks to which the target device can currently connect.

The local area network includes a wired local area network, a wireless local area network or a virtual local area network, as described above. For the wireless local area network, the detectable wireless local area network and the wireless local area network with the service set identification are included, so that the Service Set Identification (SSID) of the wireless local area network to which the target device can be connected can be obtained, and subsequent processing is facilitated. Because the local area network devices are relatively close in position, the effectiveness of transmission and delivery among messages is favorably ensured.

For example, after the smart watch establishes a communication connection with the smart air conditioner, the smart watch sends an instruction to the smart air conditioner through the established internet communication connection in a form (such as a protocol, content, and the like) predetermined with the smart air conditioner, and asks the smart air conditioner for a list of local area networks to which the smart watch can be currently connected.

Step S204, receiving the list of local area networks which can be connected currently and sent by the appointed target equipment.

After receiving the request for the list of local area networks to which the target device can be currently connected, the target device sends back the list of local area networks which the target device can be currently connected to and is stored or detected by the target device according to the actual situation of the network environment where the target device is located.

For example, after receiving a list asking for a local area network to which the smart watch can be currently connected, the smart air conditioner in the previous step searches for a local area network list stored in the smart watch and can be currently connected or detects a local area network to which the smart air conditioner can be currently connected to generate a list, then sends the list to the smart watch through the established internet communication connection according to a form (such as a protocol, content and the like) agreed with the smart watch in advance, and the smart watch receives the local area network list which the smart air conditioner can be currently connected to and sent back through the established internet communication.

In case the currently connectable local area network is a wireless local area network, the list comprises Service Set Identifiers (SSIDs) of the wireless local area networks.

Step S205, determine whether there is an available lan that the device can currently connect to in the lan list.

After receiving the list sent back by the target device, checking whether the device can be connected to the local area network in the list.

If a local area network exists in the list sent back by the target device and exists in the list stored by the local device itself, it may be considered whether an available local area network to which the local device can currently connect exists in the local area network list. Otherwise, it is considered that there is no available local area network to which the device can currently connect in the local area network list.

Or, one may try to connect to the local area networks in the local area network list sent back by the target device, and if the local area networks can be connected to the local area networks, it is determined whether there is an available local area network in the local area network list to which the device can currently connect. Otherwise, it is considered that there is no available local area network to which the device can currently connect in the local area network list.

For the smart watch described in the previous step, after receiving the local area network list that the smart air conditioner can currently connect to sent back, the local area networks in the local area network list may be compared with the local area networks in the local area network list that the smart watch can currently connect to one by one, and if a certain local area network exists in both the local area network list that the smart air conditioner can currently connect to and the local area network list that the smart watch can currently connect to, it may be determined that an available local area network that the smart watch can currently connect to exists in the local area network list that the smart air conditioner can currently connect to sent back.

The local area network in the local area network list that its can be connected to that it is sent back to and sent back to can also judge in proper order, whether intelligent wrist-watch can detect at present, if can detect and exist in the local area network list that intelligent wrist-watch can be connected to, then can judge that there is the available local area network that intelligent wrist-watch can be connected to at present in the local area network list that its can be connected to that intelligent air-conditioner sends back to.

If the smart watch in the list of the local area networks which can be currently connected to the smart air conditioner sent back cannot be detected, but the Service Set Identifier (SSID) of the smart watch is a wireless local area network which can be connected to the device, the connection can be attempted, and if the connection is possible, the connection can be judged that the available local area networks which the smart watch can be currently connected to exist in the list of the local area networks which can be currently connected to the smart air conditioner sent back.

Step S206, if there is an available local area network that the device can currently connect to in the local area network list, sending a request for requesting the specified target device to connect to the available local area network.

And sending an instruction to the target equipment through the currently connected Internet communication connection according to a form preset with the target equipment to request the target equipment to be connected to the local area network to which the local area network and the target equipment can be connected.

And if the situation that the available local area network to which the intelligent watch can be currently connected exists in the local area network list sent back by the intelligent air conditioner received by the intelligent watch, the intelligent watch sends a request to the intelligent air conditioner through the currently connected Internet according to a form (such as a protocol, content and the like) agreed with the intelligent air conditioner in advance to request the intelligent air conditioner to be connected to the available local area network. The available local area network is the local area network to which the smart watch and the smart air conditioner can be connected at present.

Step S207, receiving a confirmation message sent by the target device to connect to the available local area network.

After receiving the request for its connection to the available local area network, the target device sends back an acknowledgement message over the currently connected internet communication connection before connecting to the available local area network as requested. Receiving the confirmation message via the currently connected internet may ensure that the target device is ready to connect to the available local area network. Thus, both parties can connect to the new network for communication without interruption of communication connection due to difference of the connected networks.

After receiving a request sent by the smart watch to request the smart watch to connect to the available local area network, the smart air conditioner firstly returns a confirmation message of the request to the smart watch through the currently connected Internet. The currently connected internet is then disconnected and the smart watch is connected to the available local area network to which it requested connection.

The smart watch receives a confirmation message of the request of the smart air conditioner to connect to the available local area network designated by the smart watch, which is sent through the currently connected internet.

And step S208, disconnecting the connection with the Internet and connecting to the available local area network.

Upon receipt of the confirmation message from the target device, the device may assume that the target device has agreed to connect to the available lan and has begun to connect to the available lan, at which time the device disconnects the currently connected internet, connects to the available lan, and prepares to communicate with the target device via the available lan.

After receiving the confirmation message sent by the smart air conditioner, the smart watch in the previous step confirms that the smart air conditioner is to be connected to the available lan, disconnects from the currently connected internet, and connects to the available lan to which both the current smart watch requesting connection of the smart air conditioner and the smart air conditioner can be connected in step S206.

Step S209, communicating with the specified target device through the available local area network.

After the device is connected to the available local area network, the device establishes communication connection with the target device by using a corresponding network protocol, and sends instructions or receives data to the target device according to a form agreed in advance with the target device to carry out communication.

And after the smart watch and the smart air conditioner in the previous step are connected to the available local area network through the available local area network, starting to communicate by using a corresponding network protocol according to a form agreed in advance with the smart air conditioner. Therefore, the intelligent watch can correspondingly control the intelligent air conditioner according to the operation of the user, and sends an instruction to the intelligent air conditioner through the available local area network to change the working mode of the intelligent air conditioner or modify the working parameters of the intelligent air conditioner and the like. The smart watch can also receive and acquire the working state or some parameters of the smart air conditioner through the available local area network, such as the current working mode, the set temperature and other indexes, so as to be used by a user or an application program.

By adopting the method provided by the embodiment, the local area network can be preferentially utilized to communicate with the target equipment under the condition that the communication connection with the target equipment is established, so that the timeliness of the communication is ensured.

In correspondence with the method provided by the second embodiment of the present application, a third embodiment of the present application provides a method for communicating with a network device, which is briefly described by taking a case where a communication connection has been established between devices as an example, and a flow diagram of the method is shown in fig. 3, and includes the following steps:

step S301, receiving a request for asking for a list of local area networks to which the device can currently connect from a requester.

To communicate between devices over a local area network, a requester sends a request for a list of local area networks to which the requester can currently connect. The request is sent in a form agreed by both parties in advance, and both parties can understand and can react correspondingly. After receiving the request, the device can make a corresponding response according to the actual situation of the device.

This embodiment still takes the communication between smart watch and intelligent house equipment, such as intelligent air conditioner as an example, and this equipment is intelligent air conditioner promptly, and the requester explains for the condition of smart watch.

In this embodiment, the network where the smart air conditioner is located is not a local area network but is accessed to the internet through a telecommunication network, and at this time, a request sent by a requester, i.e., the smart watch, through the internet is received, and the request is sent to the smart watch through a local area network list to which the requester can be currently connected.

The local area network comprises a wired local area network, a wireless local area network or a virtual local area network, and the wireless local area network comprises a detectable wireless local area network and a wireless local area network with a service set identifier assigned in advance.

Step S302, sending a list of local area networks to which the device can currently connect to the requester.

After receiving a request for a list of local area networks which can be currently connected by the device and sent by a requester, finding the list or generating the list according to the network environment and the actual situation of the device, and sending the list to the requester in a double-release pre-agreed form.

For example, after receiving the request sent by the smart watch, according to the actual situation of the network where the smart air conditioner is currently located, if the current network environment is detected and a list of networks to which the smart air conditioner can be connected is reserved, the smart air conditioner sends the list of local area networks to which the smart air conditioner can be currently connected to the smart watch through the network to which the smart air conditioner is currently connected, such as the internet, according to the requirement of the smart watch.

If the list of the local area networks which can be connected to the current network environment by the user is not reserved before, the list of the local area networks which can be connected to the current network environment by the user can be detected and generated after the request of the intelligent watch is received, and then the list of the local area networks which can be connected to the user by the user is sent to the intelligent watch through the network which is connected to the user at present, such as the internet, according to the requirement of the intelligent watch.

Step S303, receiving a request sent by the requester to request the local device to connect to a specified local area network, where the specified local area network is a local area network to which the local device can currently connect.

After receiving the list, the requester can inquire whether an available local area network to which the requester can be connected currently exists, and if so, the requester can send an instruction to the equipment through the networks to which both the requester and the requester are connected currently, wherein the instruction specifies the available local area network and requests the equipment to be connected to the specified local area network. The present device receives the request.

After receiving the list of local area networks which can be currently connected to and sent by the intelligent air conditioner, the intelligent watch in the previous step takes the available local area network as a specified local area network if the available local area network which can be currently connected to is found in the list according to the actual situation of the network environment where the equipment is located, and sends a request for requesting the intelligent air conditioner to be connected to the specified local area network to the intelligent air conditioner through the network to which the intelligent air conditioner is currently connected. Reference may be made to the description relating to the second embodiment of the application for specific details.

The intelligent air conditioner receives a request sent by the intelligent watch to connect to a specified local area network through the network to which the intelligent air conditioner is currently connected.

Step S304, sending a confirmation message of the request to connect to the specified local area network to the requester.

After receiving a request sent by a requester for requesting the local device to connect to a specified local area network, firstly confirming that the local area network specified in the request instruction is a local area network in a local area network list which the local device can be currently connected to, and after confirmation, sending a confirmation message to the requester through the currently connected network to inform the requester of agreeing and committing to connect to the specified local area network.

After receiving the request sent by the smart watch to request the smart watch to connect to the designated local area network, the smart air conditioner in the previous step confirms that the designated local area network sent by the smart air conditioner to request the smart air conditioner to connect to is the local area network which can be currently connected with the smart air conditioner, that is, the designated local area network exists in the local area network list found or generated in step S302, and then sends a confirmation message to the smart phone through the currently connected network.

And step S305, disconnecting the current network and connecting to the specified local area network.

After sending the confirmation message to the requester, the network to which the requester is currently connected may be disconnected and connected to the local area network specified by the requester for communication with the requester.

And in the previous step, after the intelligent air conditioner sends a confirmation message to the intelligent watch through the network to which the intelligent air conditioner is currently connected, the intelligent air conditioner is disconnected from the current network and is connected to the local area network appointed by the intelligent watch.

Step S306, communicating with the requester through the specified local area network.

After connecting to the local area network designated by the requester, the communication with the requester requires both parties to establish communication connection in the designated local area network, and at this time, either party can actively initiate communication with the other party. Once it is confirmed that both parties are currently connected to the same lan, any application or user action triggered communication between the parties can be effected.

For example, after the smart air conditioner in the previous step is connected to the local area network designated by the smart watch, it is determined that both the smart watch and the smart air conditioner are connected to the same local area network, that is, the local area network designated by the smart watch, and both parties can communicate with the smart watch through the designated local area network. Therefore, the intelligent air conditioner can execute corresponding functions such as changing the working mode, modifying working parameters and the like according to the instruction sent by the intelligent watch through the specified local area network. The smart air conditioner can also send related parameters such as the current working mode, the set temperature and the like to the smart watch through the designated local area network so as to be used by a user or an application program of the smart watch.
