[0166] A local area network can interconnect multiple user equipment (UE) in an area into a network. As a basic network facility, local area networks have been applied to various scenarios such as enterprises, homes and industries. With the continuous advancement of technology, the communication functions of local area networks have become increasingly rich, and have gradually integrated multiple functions such as email, blogs, music, television, games and search. It is no longer a simple chat tool, but has developed into an integrated information platform that integrates communication, information, entertainment, search, e-commerce, office collaboration and corporate customer service. It is a terminal networking instant messaging network service. Local area network communication usually realizes the communication of terminal devices through routers. Terminal devices under the same router have the same network segment, so they can be interconnected. However, terminal devices under different routers have different network segments and cannot be interconnected.

[0167] In view of the above problems, the embodiments of the present application provide a communication method, device, equipment and storage medium based on a virtual local area network, which realizes the interconnection between terminal devices in different local area networks. Specifically, the terminal devices in the same local area network have the same network segment and can be interconnected through the same router, while the terminal devices in different local area networks have different network segments and have network isolation, and cannot be interconnected. Considering these problems, the inventor studied whether it is possible to form a virtual local area network with terminal devices in different local area networks, and to realize the interconnection between terminal devices by deploying a server and a client. Based on this, the technical solution of the present application is proposed.

The method includes:

[0177] S301: Acquire a service message to be sent by monitoring a virtual interface through a first client.

[0178] In this step, when the terminal devices in different local area networks communicate with each other, the user initiates the terminal service through the first terminal, and the first terminal obtains the service message according to the terminal service and transmits it to the virtual interface, and the client deployed in the first terminal obtains the service message to be sent by monitoring the virtual interface. The service message includes the IP address of the second client at the message receiving end.

[0179] Optionally, the specific method for the user to initiate a terminal business service through the first terminal may be by directly inputting information into an application in the first terminal, or by touching the screen or buttons of the first terminal to initiate a command. The first terminal starts the terminal business service according to the command initiated by the user. The terminal business service may be a call service, a video transmission service, a text transmission service, etc.

[0180] This application does not specifically limit the specific method in which the user initiates the terminal business service and the specific content of the terminal business service.

[0181] S302: encapsulate the service message according to the pre-acquired virtual local area network configuration information to obtain a transmission message.

[0182] In this step, after obtaining the service message, the first client encapsulates the service message according to the pre-acquired virtual LAN configuration information to obtain a transmission message in order to communicate data with the second client at the message receiving end and ensure data security.

[0183] Specifically, the service message is first tunnel-encapsulated to obtain an encapsulated message, and then the encapsulated message is encrypted and compressed to obtain a transmission message.

[0184] S303: According to the IP address of the second client, transmit the transmission message to the second client through the virtual local area network.

[0185] In this step, the first client processes the service message to obtain a transmission message, and then transmits the transmission message to the second client through the virtual local area network according to the IP address of the second client.

[0186] Specifically, the configuration information also includes peer-to-peer communication information, and any client can choose to enable peer-to-peer communication or not based on the peer-to-peer communication information. Clients that enable peer-to-peer communication in the same virtual local area network can open peer-to-peer communication channels.

[0187] This step can be implemented in the following two ways:

[0188] The first implementation method: The first client detects whether a point-to-point communication channel is established between the first client and the second client based on the IP address of the second client. If a point-to-point communication channel is established between the first client and the second client, the first client can directly transmit the transmission message to the second client through the point-to-point communication channel between the first client and the second client.

[0189] Second implementation method: If a point-to-point communication channel is not established between the first client and the second client, the first client needs to transmit the transmission message to the server, and the server transfers the transmission message and transmits it to the second client.

[0190] It should be noted that the communication method between any client and server and between clients can be any one of the User Datagram Protocol (UDP) protocol, Transmission Control Protocol / Internet Protocol (TCP / IP) protocol, Internetwork Packet Exchange / Sequences Packet Exchange (IPX / SPX) protocol, and NetBios Enhanced User Interface (NetBEUI) protocol based on Internet Protocol version 4 (IPv4) or Internet Protocol version 6 (IPv6), and this embodiment does not make any specific limitation.

[0191] S304: Decapsulate the transmission message according to the pre-acquired virtual local area network configuration information to obtain a service message.

[0192] In this step, after receiving the transmission message transmitted by the first client, the second client decapsulates the transmission message according to the pre-acquired virtual local area network configuration information to obtain the service message in order to complete the terminal service content.

[0193] Specifically, the second client first decompresses the transmission message according to the configuration information, then decrypts it, and finally unblocks the tunnel to obtain the service message. The second client transmits the service message to the corresponding application through the virtual interface deployed by the second terminal, and the user completes the operation in the corresponding application according to the service message.

[0194] In one possible implementation, Figure 1Based on the scenario shown, the same virtual LAN may include multiple terminals, each of which has a client deployed. When data communication is performed through the virtual LAN, the service message may not specify the IP address of the client at the message receiving end, or may include the IP addresses of multiple clients at the message receiving end.

[0195] For example, if the IP address of the client at the message receiving end is not specified in the service message, the terminal device initiating the service is terminal device A, and a first client is deployed in terminal device A, then the first client transmits the transmission message through router A to the server deployed in network device 100, and the server transmits the transmission message to the clients deployed in terminal device B, terminal device C, terminal device D, terminal device E, terminal device F, terminal device G, terminal device H, and terminal device I.

[0196] Exemplarily, if the business message specifies multiple IP addresses of clients at the message receiving end, the terminal device initiating the service is terminal device A, a first client is deployed in terminal device A, and the terminal devices corresponding to the IP addresses of multiple clients at the message receiving end specified in the business message are terminal device D, terminal device E, and terminal device H, then the first client respectively detects whether point-to-point communication channels are opened between the clients deployed in terminal device D, terminal device E, and terminal device H. If the point-to-point communication channel is opened, the transmission message is transmitted to the corresponding client through the point-to-point communication channel. If it is not opened, the transmission message is transferred to the corresponding client through the server.

[0197] The communication method based on virtual local area network provided in this embodiment obtains the service message to be sent by monitoring the virtual interface through the first client, and then encapsulates the service message according to the pre-acquired configuration information of the virtual local area network to obtain the transmission message, and then transmits the transmission message to the second client through the virtual local area network according to the IP address of the second client, and finally the second client decapsulates the transmission message according to the pre-acquired configuration information of the virtual local area network to obtain the service message. Through the above method, data communication between terminal devices in different local area networks is realized, thereby improving the communication efficiency between users.

[0198] Figure 5 A flow chart of a second embodiment of a communication method based on a virtual local area network provided in the present application is shown in FIG. Figure 5 As shown, based on the above embodiment, the configuration information of the virtual local area network includes message compression information and message encryption information, and step S302 can be implemented by the following steps:

[0199] S501: Perform tunnel encapsulation on the service message to obtain an encapsulated message.

[0200] S502: Encrypt the encapsulated message according to the message encryption information, and compress the compressed and encrypted message according to the message compression information to obtain a transmission message.

[0201] In order to improve information security, the encapsulated message is encrypted according to the message encryption information. In order to save network bandwidth and improve transmission efficiency, the encrypted message is compressed according to the message compression information to obtain the transmission message.

[0202] Specifically, the encapsulated message can be encrypted using a symmetric encryption algorithm or an asymmetric encryption algorithm. For example, the symmetric encryption algorithm can use the Advanced Encryption Standard (AES) or the Data Encryption Standard (DES) or 3DES. The asymmetric encryption algorithm can use a public key algorithm or a Digital Signature Algorithm (DSA) or Elliptic Curves Cryptography (ECC). This application does not specifically limit the encryption method.

[0203] The communication method based on the virtual local area network provided in this embodiment realizes the transmission of the message by encapsulating, encrypting and compressing the service message, thereby saving network bandwidth and improving transmission efficiency and data security.

[0204] In a possible design, based on the aforementioned embodiments, the client needs to join the virtual LAN before performing data communication through the virtual LAN. The specific joining method can be implemented in the following two ways.

[0205] The first way, Figure 6 The flowchart of the third embodiment of the communication method based on the virtual local area network provided in the embodiment of the present application is shown in FIG. Figure 6 , which can be achieved through the following steps:

[0206] S601: Receive the authentication field sent by the cloud platform for joining the virtual local area network configuration, the IP address of the server, and the IP addresses of all clients.

[0207] In this step, when the network device and the terminal device are connected to the same cloud platform, the cloud platform can be used to establish a virtual local area network. The cloud platform configures the authentication field and IP address for establishing the virtual local area network.

[0208] The client receives the authentication field configured for joining the virtual LAN, the server's IP address, and the IP addresses of all clients sent by the cloud platform through the communication interface.

[0209] It is worth noting that users can instruct terminal devices to form a virtual LAN on the cloud platform.

[0210] S602: Send a virtual local area network access request to the server according to the IP address of the server, the authentication field and the IP address of the client.

[0211] In this step, after the client receives the authentication field sent by the cloud platform, the IP address of the server and the IP addresses of all clients, it sends a virtual LAN access request to the server according to the IP address and authentication field of the server.

[0212] S603: Verify the authentication field in the LAN access request according to the authentication field configured by the cloud platform.

[0213] In this step, after receiving the virtual LAN access request sent by the client, the server verifies the authentication field sent by the client according to the virtual LAN access request.

[0214] Specifically, the server compares the authentication field sent by the client with the authentication field configured by the cloud platform. If the authentication field sent by the client is the same as the authentication field configured by the cloud platform, the client is verified. If the authentication field sent by the client is different from the authentication field configured by the cloud platform, the client fails the verification.

[0215] S604: After the authentication field is verified, the client is allowed to access the virtual local area network corresponding to the IP address of the server.

[0216] In this step, the server verifies the authentication field sent by the client. After the authentication field verification is passed, the client is allowed to access the virtual local area network corresponding to the IP address of the server and establishes a communication connection with the client.

[0217] S605: Return an access confirmation message to the client.

[0218] In this step, after the server allows the client to access the virtual local area network, it returns an access confirmation message to the client through the communication connection established with the client, and the client receives the access confirmation message returned by the server. The access confirmation message is used to indicate that the client has successfully accessed the virtual local area network.

[0219] Optionally, after the cloud platform configures the authentication field, the IP address of the server, and the IP addresses of all clients for joining the virtual LAN, the authentication field, the IP address of the server, and the IP addresses of all clients need to be sent to the server.

[0220] The communication method based on virtual local area network provided in this embodiment is that the user specifies the terminal device for forming the virtual local area network, the cloud platform configures the authentication field and IP address, and sends it to the client and the server. The client requests the server to access the virtual local area network according to the IP address and authentication field of the server. After the authentication field of the client is verified, the server returns an access confirmation message to the client. Through the above method, the formation of the virtual local area network is realized, and then the communication between terminal devices in different local area networks is realized.

[0221] The second method, Figure 7 The flowchart of the fourth embodiment of the communication method based on the virtual local area network provided in the embodiment of the present application is shown in FIG. Figure 7 , which can be achieved through the following steps:

[0222] S701: Scan the uplink network device of the terminal through the client to obtain the network device of the server where the virtual local area network is deployed.

[0223] In this step, if you want to build a virtual LAN, you need to establish communication between the client and the server, and the client scans the uplink network device of the terminal to obtain the network device of the server where the virtual LAN is deployed.

[0224] Specifically, since the server may be deployed in the top network device, the client scans the upstream network device of the terminal layer by layer, scans the server that deploys the virtual LAN and turns on the server's network device, and then obtains the server's IP address.

[0225] S702: Send a virtual local area network joining request to a server in the network device.

[0226] In this step, after obtaining the IP address of the server, a virtual local area network joining request is sent to the server in the network device through a communication connection.

[0227] S703: If the virtual local area network joining request does not carry the IP address of the client, the client is allowed to join the virtual local area network and an IP address is allocated to the client.

[0228] In this step, after receiving the virtual LAN joining request sent by the client, the server queries whether the virtual LAN joining request carries the client's IP address. If the virtual LAN joining request does not carry the client's IP address, it means that the client has not joined any virtual LAN. In this case, the client is allowed to join the virtual LAN and an IP address is allocated to the client.

[0229] S704: Send a virtual local area network joining feedback message to the client.

[0230] In this step, after the server allocates an IP address to the client, it generates a virtual local area network joining feedback message, and sends the virtual local area network joining feedback message to the client through the communication connection.

[0231] S705: If the virtual LAN joining request carries the IP address of the client, it is detected whether the IP address of the client is used by other clients.

[0232] In this step, after receiving the virtual LAN joining request sent by the client, the server checks whether the virtual LAN joining request carries the client's IP address. If the virtual LAN joining request carries the client's IP address, it means that the client may have applied repeatedly. Therefore, the server detects whether the client's IP address is used by other clients.

[0233] Specifically, the IP address of the client is compared with the IP addresses of other clients that have joined the virtual LAN. If the IP address of the client is the same as the IP addresses of other clients that have joined the virtual LAN, then the client is applying repeatedly. If the IP address of the client is different from the IP addresses of other clients that have joined the virtual LAN, then the client is not applying repeatedly.

[0234] S706: If the IP address of the client is not used by other clients, the client is allowed to join the virtual LAN.

[0235] In this step, the IP address of the client is detected by the server. If the IP address of the client is not used by other clients, it means that there is no duplicate application by the client, and the client is allowed to join the virtual LAN.

[0236] S707: Send a virtual local area network joining feedback message to the client.

[0237] The specific implementation of this step is the same as that of step S704, and will not be repeated here.

[0238] S708: If the IP address of the client is used by other clients, the client is not allowed to join the virtual LAN, and a virtual LAN joining feedback message indicating a failure to join the LAN is returned to the client.

[0239] In this step, the IP address of the client is detected by the server. If the IP address of the client is used by other clients, it means that the client has made a duplicate application. The client is not allowed to join the virtual LAN, and a virtual LAN joining feedback message indicating that the LAN joining failed is returned to the client through the communication connection.

[0240] Optionally, after receiving the virtual LAN joining feedback message returned by the client, if the virtual LAN joining feedback message indicates that the client has successfully joined the virtual LAN, the virtual LAN joining feedback message also includes the authentication field and configuration information configured by the server, wherein the configuration information includes message compression information, message encryption information and the IP addresses of all clients in the virtual LAN.

[0241] In the communication method based on virtual local area network provided in this embodiment, the client scans the network device of the deployed server, obtains the IP address of the server, and sends a virtual local area network joining request to the server. The server verifies the client according to the virtual local area network joining request. If the verification is passed, the client is allowed to join the virtual local area network. If the verification is not passed, the client is not allowed to join the virtual local area network. Through the above method, security is improved, and interconnection between terminal devices in different local area networks is realized.

[0242] It should be noted that the client in the two embodiments of forming a virtual local area network may be the first client mentioned above, or may be the second client, or may be any other client.

[0243] Figure 8 The flowchart of the fifth embodiment of the communication method based on the virtual local area network provided in the embodiment of the present application is shown in FIG. Figure 8 On the basis of the above embodiments, the configuration information of the virtual local area network includes message compression information and message encryption information, and step S304 can be implemented by the following steps:

[0244] S801: Decompress the transmission message according to the message compression information to obtain a decompressed message.

[0245] S802: Decrypt the decompressed message according to the message encryption information, and perform tunnel decapsulation to obtain a service message.

[0246] After the second client at the message receiving end receives the transmission message, it decompresses, decrypts and unblocks the tunnel of the transmission message according to the configuration information of the virtual LAN to obtain the service message, and transmits the service message to the application corresponding to the second terminal through the virtual interface for service operation.

[0247] The communication method based on virtual local area network provided in this embodiment decompresses, decrypts and unblocks the transmission message by using the same configuration information as the first client sending the message, thereby saving network bandwidth and improving transmission efficiency and data security.
