Description

A communication method, a readable medium and an electronic device

Technical Field

The present application relates to the field of smart home, and in particular to a communication method, a readable medium and an electronic device.

Background technique

As living conditions improve, the number and area of rooms in a house are constantly increasing. In order to ensure that a better Wi-Fi signal can be received in each room of the house, residents usually install multiple wireless routers in the house, and multiple wireless routers are simultaneously connected to an optical modem, that is, an optical modem. For example: as shown in FIG1 , Wi-Fi routers 100-1, 100-2, and 100-3 are installed in bedroom A, bedroom B, and living room of the house, and Wi-Fi routers 100-1, 100-2, and 100-3 are simultaneously connected to an optical modem 200. When users use the Internet through smart devices in bedroom A, bedroom B, and living room, respectively, the smart devices can respectively connect to Wi-Fi routers 100-1, 100-2, or 100-3 to browse the Internet through optical modem 200.

However, since Wi-Fi routers 100-1, 100-2 or 100-3 each have different network segments and service set identifiers (SSID) information, the smart devices under Wi-Fi router 100-1 and the smart devices of Wi-Fi router 100-2 are invisible to each other and cannot access each other, that is, smart devices connected to different routers cannot access each other. For example: Continuing with Figure 1, the tablet computer 300 connected to Wi-Fi router 100-1 in bedroom A cannot access the printer 400 connected to Wi-Fi router 100-3 in the living room. If the user needs to print materials for online classes in bedroom A, the mobile phone 300 must be switched to Wi-Fi router 100-3 to print, which may cause the online class to be interrupted, and the operation is cumbersome, and the user experience is poor.

Detailed ways

Illustrative embodiments of the present application include, but are not limited to, a communication method, a readable medium, and an electronic device.

In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the embodiment of the present application will be described clearly and in detail in conjunction with the accompanying drawings. In the description of the embodiment of the present application, unless otherwise specified, "/" means or, for example, A/B can mean A or B; "and/or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

Some terms in this application are explained below to facilitate understanding by those skilled in the art.

A network segment refers to a part of a computer network that can communicate directly using the same physical layer devices (routers, repeaters, hubs, etc.).

The application layer protocol is used for application programs running on systems of different electronic devices to transmit messages to each other.

Continuing to refer to FIG. 1 , FIG. 1 exemplarily shows a scenario diagram of a smart network corresponding to a residence provided in an embodiment of the present application. As shown in FIG1 , resident A uses a tablet computer 300 in bedroom A to take an online class through a Wi-Fi router 100-2, and resident B uses a laptop computer 500 in bedroom B to conduct a video conference through a Wi-Fi router 100-3. If resident A needs to print materials through a printer 400 connected to the Wi-Fi router 100-1 during the online class or the video conference of resident B, then resident A or resident B needs to switch to the Wi-Fi router 100-1 to access and use the printer 400. Since the Wi-Fi router 100-1 is set in the living room, the Wi-Fi signal sent by the Wi-Fi router 100-1 in bedrooms A and B may be weak, resulting in the online class and video conference being stuck or interrupted after the tablet computer 300 and the laptop computer 500 are connected to the Wi-Fi router 100-1. If residents A and B move the tablet computer 300 and the laptop computer 500 to the living room and then switch to the Wi-Fi router 100-1, it will cause great inconvenience.

Referring to Figure 2, Figure 2 exemplarily shows a schematic diagram of a scenario of network connection between various smart devices in a residence provided by an embodiment of the present application. As shown in Figure 2, Wi-Fi routers 100-1, 100-2 and 100-3 are simultaneously connected to an optical modem 200 via a network cable, and can be set in a weak current box of a residence. Tablet computer 300 is connected to Wi-Fi router 100-2, laptop computer 500 is connected to Wi-Fi router 100-3, and printer 400 is connected to Wi-Fi router 100-1. As can be seen from Figure 2, Wi-Fi routers 100-1, 100-2 and 100-3 have their own SSID information respectively. At the same time, since the optical modem 200 also assigns different IP addresses to Wi-Fi routers 100-1, 100-2 and 100-3, for example: the IP addresses are 192.168.0.2, 192.168.0.3 and 192.168.0.4 respectively. Although the Wi-Fi routers 100-1, 100-2 and 100-3 are in the network segment corresponding to the optical modem 200, the Wi-Fi routers 100-1, 100-2 and 100-3 and the tablet computer 300, the laptop computer 500 and the printer 400 respectively operate in different network segments of the Wi-Fi routers. That is, the Wi-Fi routers 100-1, 100-2 and 100-3 respectively allocate different network segments to the tablet computer 300, the laptop computer 500 and the printer 400, so that the tablet computer 300, the laptop computer 500 and the printer 400 are invisible to each other and cannot access each other.

It can be understood that different network devices connected to the same optical modem can send information to each other through the network segment corresponding to the optical modem, that is, different network devices connected to the same optical modem can communicate with each other. Therefore, in order to solve the problem that the intelligent devices connected to different network devices involved in Figures 1 and 2 above cannot access each other, an embodiment of the present application provides a communication method. In this method, different network devices connected to the same optical modem send their respective connection information in the network segment corresponding to the optical modem by multicast, wherein the connection information can carry the SSID information of each network device and the information of the supported communication channel. In this way, after receiving the connection information of other network devices, the network device can determine which network devices can support the communication channel, and establish communication channels between different network devices through security authentication and encryption negotiation between each network device that supports the communication channel. The communication channels between different network devices can be used to realize the communication between terminal devices hanging under different network devices.

After the communication channel is established, a network device with performance parameters that meet the conditions is determined as a master network device based on the performance parameters of multiple network devices, and multiple network devices are set using the IP address and SSID information of the master network device, and parameters are synchronized between multiple network devices so that multiple network devices have the same network segment and SSID information, that is, the same Wi-Fi network parameters are provided in each room in the house. If each of the multiple network devices that have established the communication channel is connected to at least one smart device, the smart devices under each network device can transmit information through the communication channel, that is, the smart devices under different network devices work under the same network segment, and the smart devices under different network devices can access and communicate with each other through the communication channel that has been set up.

Through the communication method provided in the embodiment of the present application, a communication channel is established between multiple network devices in a residence, and a unified network segment and SSID information are set, so that smart devices in the residence can access the same network segment, thereby achieving mutual access and communication between smart devices and improving user experience; if a user carries a smart device around the residence, the smart device can also achieve seamless switching from one network device to another, without causing temporary network interruption to the smart device.

The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the operating system of the network device 100 can be divided into four layers, from top to bottom, namely, the application layer, the application state service layer, the middleware layer, and the kernel layer.

The following describes the network connection process of an embodiment of the present application based on the interaction diagram of the network device shown in Figure 5. In Figure 5, only Wi-Fi router 100-1, Wi-Fi router 100-2 and optical modem 200 are shown. In some embodiments, more Wi-Fi routers may be included, which is not limited here.

S501: The Wi-Fi router 100-1 and the Wi-Fi router 100-2 are respectively connected to the optical modem 200.

Exemplarily, as shown in FIG. 2 , the optical modem 200 here can be set in a low-voltage box of a residence. One port of the optical modem 200 is connected to the optical fiber communication network for converting optical signals. The optical modem 200 can also provide multiple local area network ports, that is, LAN ports, for connecting the interfaces of terminal devices or next-level network devices. The Wi-Fi router 100-1 and the Wi-Fi router 100-2 can also access the optical modem 200 through the local area network port, that is, the LAN port; the Wi-Fi router 100-1, the Wi-Fi router 100-2 and the optical modem 200 form a network segment, and the optical modem 200 can assign IP addresses to the Wi-Fi router 100-1 and the Wi-Fi router 100-2.

S502: The Wi-Fi router 100-1 multicasts the connection information via the optical modem 200.

Exemplarily, the Wi-Fi router 100-1 can multicast connection information in the network segment between the Wi-Fi router 100-1 and the optical modem 200, that is, send the connection information in the IP address of the network segment of the optical modem 200 to determine whether other network devices that are also connected to the optical modem 200 can receive the connection information. For example: the Wi-Fi router 100-1 and the Wi-Fi router 100-2 can exchange connection information in the network segment corresponding to the optical modem 200. The connection information here can carry the SSID information (SSID1) of the Wi-Fi router 100-1 and the information that the Wi-Fi router 100-1 supports the communication channel, that is, the information that the Wi-Fi router 100-1 supports smart connection.

In some embodiments, for example, as shown in FIG. 6 , the Wi-Fi router 100 - 1 and the Wi-Fi router 100 - 2 may respectively run a CoAP server and a CoAP client, wherein the CoAP client is used to multicast connection information and the CoAP server is used to receive and parse the connection information.

S503: After the Wi-Fi router 100-2 receives the connection information, a connection is established between the Wi-Fi router 100-1 and the Wi-Fi router 100-2.

Exemplarily, when Wi-Fi router 100-2 receives the connection information sent by Wi-Fi router 100-1, Wi-Fi router 100-2 may parse the connection information, and when it is determined that Wi-Fi router 100-1 supports the communication channel and Wi-Fi router 100-2 itself also supports the communication channel, a connection is established between Wi-Fi router 100-1 and Wi-Fi router 100-2 for mutually sending information corresponding to security authentication and encryption negotiation.

S504: The Wi-Fi router 100-1 and the Wi-Fi router 100-2 perform security authentication and encryption negotiation to establish a communication channel.

Exemplarily, after a connection is established between the Wi-Fi router 100-1 and the Wi-Fi router 100-2, taking the Wi-Fi router 100-1 as an example, the security authentication process may include: the Wi-Fi router 100-1 sends a message, the message carries the SSID information of the Wi-Fi router 100-1; after the Wi-Fi router 100-2 identifies that the SSID information carried in the message belongs to the Wi-Fi router 100-1, it generates verification information; returns it to the Wi-Fi router 100-1; the Wi-Fi router 100-1 sends a message carrying the verification information; after the Wi-Fi router 100-2 identifies the verification information carried in the message again, it determines that the verification is passed. The encryption negotiation process may include: the Wi-Fi router 100-1 and the Wi-Fi router 100-2 determine the encryption methods that they both support, such as: WEP (Wired Equivalent Privacy), etc.

In some embodiments, the communication channel here can be established through CoAP (Costrained Application Protocol). Wi-Fi router 100-1 and Wi-Fi router 100-2 can transmit information through request messages and response messages corresponding to CoAP. For example, referring to Figure 6, Wi-Fi router 100-1 and Wi-Fi router 100-2 can run CoAP server (CoAP server) and CoAP client (CoAP client) respectively, and CoAP client is used to send request messages, and CoAP server user replies to response messages. Request messages and response messages can be transmitted in a unicast manner.

S505: The Wi-Fi router 100-1 and the Wi-Fi router 100-2 perform capability negotiation to confirm that the Wi-Fi router 100-1 is the primary network device.

Exemplarily, after a communication channel is established between Wi-Fi router 100-1 and Wi-Fi router 100-2, Wi-Fi router 100-1 and Wi-Fi router 100-2 may determine a main network device (target network device) based on performance parameters, such as processor model, transmission rate, system version, etc., that is, parameters of each network device for synchronizing the established communication channel.

S506: The Wi-Fi router 100-1 and the Wi-Fi router 100-2 perform parameter synchronization and send network connection parameters.

Exemplarily, as shown in FIG7 , the Wi-Fi router 100-1 as the main network device can synchronize the SSID information, the network segment corresponding to the IP address, the password, and the Wi-Fi parameters (network parameters) of the Wi-Fi router 100-2 through the communication channel to be consistent with the Wi-Fi router 100-1. It can be understood that when the Wi-Fi router 100-3 is connected to the optical modem 200 and the Wi-Fi router 100-3 also supports the communication channel, the Wi-Fi router 100-1 can also synchronize the SSID information and the network segment corresponding to the IP address of the Wi-Fi router 100-3 through the communication channel to be consistent with the Wi-Fi router 100-3. Referring to FIG7 , the SSID information of the Wi-Fi router 100-2 and the Wi-Fi router 100-3 is synchronized to SSID1.
