20250173112
The present disclosure claims a priority of Chinese patent application No. 202210430422.7, filed with CNIPA on Apr. 22, 2022, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the field of communication, and in particular to a method, equipment, apparatus for connecting devices, and storage medium.
Currently, with the continuous development of network technology, wireless screen projection technology has been increasingly utilized in the fields of office and education. Before wireless screen projection is initiated, it is necessary to input a connection code in the projection sending end to establish a connection between the projection sending end and a projection receiving end. The current connection code can only be used in scenarios where both the projection sending and receiving ends are located within the same local area network (LAN). The connection code is used as at least one of the random verification codes or address codes. However, when the projection sending end is only connected to a wide area network (WAN), or when the projection sending end cannot directly connect to an address of the projection receiving end, the projection sending end cannot connect to the projection receiving end through the connection code. Furthermore, some high-security environments may be incompatible with connection codes, even resulting in unusable situations.
According to embodiments of the present disclosure, a method, equipment, apparatus for connecting devices, and storage medium are provided, which can improve a success rate of device connection while being compatible with LAN and WAN, thus solving the technical problem of poor connection code compatibility and a low success rate of device connection in existing technology.
According to a first aspect of the present disclosure, a method for connecting devices is provided, which includes:
According to a second aspect of the present disclosure, a method for connecting devices is provided, which includes:
According to a third aspect of the present disclosure, equipment for connecting devices is provided, which includes a connection-code generating module, a connection-code displaying module, and a connection responding module;
According to a fourth aspect of the present disclosure, equipment for connecting devices is provided, which includes a connection-code receiving module, a first connection-code requesting module, a first connection requesting module, a second connection-code requesting module, and a second connection requesting module;
According to a fifth aspect of the present disclosure, an apparatus for connecting devices is provided, which includes a processor and a memory;
According to a sixth aspect of the present disclosure, a storage medium for storing computer executable instructions is provided, the computer executable instructions are used to perform a method for connecting devices as mentioned in the first or second aspect when executed by a computer processor.
As mentioned above, according to an embodiment of the present disclosure, the second device only needs to display a connection code, so that the first device is connected to the second device through a LAN or a WAN, which can be compatible with the network environment of both the LAN and the WAN. In addition, the user only needs to obtain one connection code during use, and does not need to obtain different connection codes for repeated connection operations. Regardless of whether the first or second connection code is displayed, the user performs the same connection operation on the first device. The user does not need to learn different operations for different connection codes, which reduces learning and operation costs of the user. The embodiments of the present disclosure can address the technical problems of poor connection code compatibility and low device connection success rate in the existing technologies.

As shown in
After the first device 10 and the second device 20 are connected, they can engage in information exchange. For example, the first device 10 may send currently displayed screen data to the second device 20, and the currently displayed screen data may include one or more of audio data and video data. After the screen data sent by the first device 10 is received, the second device 20 may process the received screen data and display it on its own page to achieve screen projection. For example, the first device 10 may encode the current screen data and send the encoded screen data to the second device 20. The second device 20 receives the encoded screen data and decodes it to obtain the decoded screen data. The second device 20 may display the decoded screen data. The following description provides a specific explanation using the example of the first device 10 and the second device 20 being connected via a wireless local area network.
For example, as shown in
Based on this, according to an embodiment of the present disclosure, a method for connecting devices is provided, as shown in
Step 101, generating a first connection code based on device information, and sending the first connection code and a request for a second connection code to a server, so that the server stores the first connection code and the second connection code in association, where the first connection code is used as at least one of a verification code or an address code for LAN, and the second connection code is used as a verification code for WAN.
In this embodiment, the second device 20 first generates a first connection code based on its own device information. The device information includes, for example, LAN IP, service port number, hotspot IP, hotspot Service Set Identifier (SSID), hotspot password, and/or physical address. The LAN IP refers to a network address of LAN. The service port number refers to the port number of the server 30. Various services in the server 30 may use different ports to provide different services, and the port number of the server 30 refers to the number in different ports. The hotspot refers to a device converting GPRS, 3G, or 4G signals into wireless LAN signals and broadcasting them for use by other devices. The hotspot IP refers to an address of wireless LAN. Hotspot SSID refers to dividing wireless LAN of a hotspot into several subnetworks that require different authentication. Each subnetwork requires independent authentication, and only authenticated users can enter the corresponding subnetwork to prevent unauthorized users from entering the wireless LAN. The hotspot password refers to a password required to connect to the wireless LAN of the hotspot. Only when the correct password is entered can one connect to the hotspot. The physical address refers to an address of the device that broadcasts hotspots, which is set by the manufacturer at the factory to identify each device in the network.
The first connection code refers to a connection code used to connect different devices within the same LAN. In this embodiment, the first connection code is used as either a verification code or an address code in the LAN, that is, the first connection code may be used as the verification code of LAN, as the address code of LAN, or as both the verification code and address code of LAN. Verification code refers to the connection code used to match a specific device, and the verification code includes verification information of the device. For example, the first device 10 discovers a list of the second devices 20 through protocols on LAN (such as the Simple Service Discovery Protocol or Multicast DNS protocol), and then matches a specific receiving end from the list of the second devices 20 through a connection code to indirectly discover and connect to the second device 20. Address code refers to a connection code that contains IP address information, and the address code includes IP address information of the device. For example, information such as an IP address is mapped into a connection code through a certain mapping relationship. After a projection sending device inputs the connection code, the projection sending device can directly discover and connect to the projection receiving device.
In one embodiment, the first connection code defaults to a six-character connection code. The character refers to a type of glyph unit or symbol, including letters, numbers, arithmetic symbols, punctuation marks, and other symbols, as well as some functional symbols. In this embodiment, the characters of the first connection code may be composed of any one or more of numbers or letters. For example, the first connection code may be CDF96Q or WS7U89, etc. In this embodiment, the specific content of the first connection code is not limited. Understandably, the first connection code may be expanded to 7 or more characters, which may add more IP address information, change bits, ports, or other network information. Specifically, in this embodiment, the second device 20 generates a first connection code based on its own device information. Specifically, based on the RFC 1918 standard, IPv4 private addresses in LAN are divided into four segments, as shown in Table 1:
Due to the fact that the first connection code is a six-digit or six-letter connection code, including total 36 characters, with digits from 0-9 and letters from A-Z (case insensitive), after excluding the digits “0” and “1”, as well as the letters “I” and “O” that are easily recognizable by users, there are 32 remaining characters.
Therefore, the encoding space of the connection code is 326=230, or a 30-bit binary encoding space for storing content.
After the IPV4 private address is divided, the first device 10 fills 30 binary bits of the connection code with information such as IP address, port, random bit, parity bit, and type bit. Specifically, when the IP address of the second device 20 is an address of Class A private segment, the binary bits of the connection code represent type, parity bit, port, and IP address information in descending order, as shown in Table 2:
When the IP address of the second device 20 is a Class B private segment address, the binary bits of the connection code represent type, parity bit, port, and IP address information in descending order, as shown in Table 3:
When the IP address of the second device 20 is a Class C private segment address, the binary bits of the connection code represent the type, parity bit, port, and IP address information in descending order, as shown in Table 4:
The Type bit represents the type of IP address. The Type bit is set to 00 for Class A private addresses, 01 for Class B private addresses, 10 for Class C private addresses, and 11 for reserved extended segments. The Parity bit is calculated by taking a modulus 4 of a number composed of all bits in the connection code except for the Parity bit itself. The Parity bit is calculated for the connection code input by the user and compared with the parity bit saved in the connection code to determine whether the user made an error in inputting the code. The Change bit is randomly generated within the range of 0 to 15. In order that the Change bits can affect other parts, the Change bits are replaced with any four other bits to avoid the situation where only one character of the six connection codes changes. Port, used to store the index in a port array, is determined based on the service port number in the device information. The IP address information represents the IP address of the second device 20 in LAN, which may be obtained from the LAN IP in the device information.
After the first connection code is generated, the second device 20 uploads the first connection code to the server 30. The server 30 refers to a device that provides computing or application services to other devices in the network. At the same time, the second device 20 sends a request for a second connection code to the server 30. After the request is received, the server 30 generates a second connection code and stores the second and first connection codes in association. It should be noted that in this embodiment, the second connection code is the connection code used in WAN, which can enable different devices in WAN to be connected. WAN refers to a remote network that connects computer communication in different LAN or metropolitan area network (MAN). Since different devices in WAN can access each other, each WAN connection code must ensure uniqueness. Otherwise, there may be cases of erroneously connecting to other devices, leading to serious problems such as information leakage. Therefore, the second connection code is used as a verification code in WAN to match specific devices in WAN. In one embodiment, the server 30 may use the IP address in the first connection code as the connection code corresponding to the reserved extension segment as the WAN connection code.
Step 102, displaying the first or second connection code to receive a connection request sent by the first device through the local area network or the wide area network, where the connection request is generated by the first device based on the first or second connection code.
After a request for a second connection code is sent to the server 30, the second device 20 may display either the first or second connection code. For example, the second device 20 may display the connection code at a random position on the screen or display the connection code in a specific area on the screen. If the second device 20 needs to display the first connection code, the first connection code returned by the server 30 needs to be received. Subsequently, the user inputs the first or second connection code into the first device 10 based on the first or second connection code displayed on the second device 20. After the first or second connection code is received, the first device 10 generates a connection request based on the first or second connection code. The connection request is used to request for connection to the second device 20, the connection request is generated based on the first or second connection code received from the first device 10. For example, as shown in
When the second device 20 displays the second connection code, the user inputs the second connection code into the first device 10. In one embodiment, after the first device 10 receives the second connection code, a connection request may be directly sent to the second device through WAN based on the second connection code, allowing the first device and the second device to connect through WAN. In another embodiment, after the second connection code is received, the first device 10 obtains the first connection code associated with the second connection code from the server 30 based on the second connection code and sends a connection request to the second device 20 through LAN based on the first connection code. If the first device 10 fails to connect to the second device 20 through LAN, the first device 10 sends a connection request to the first device 10 through WAN based on the second connection code, so that even when the user inputs the second connection code, the first device 10 may be connected to the second device 20 through LAN.
Step 103, in response to the connection request, connecting to the first device through the local area network or wide area network.
After the connection request is received from the first device 10, if the connection request is sent through LAN, the second device 20 establishes a connection with the first device 10 through LAN. If the connection request is sent through WAN, the second device 20 establishes a connection with the first device 10 through WAN.
As mentioned above, while the generated first connection code is uploaded to the server, the second device applies for a second connection code to the server. If the second device does not receive the second connection code, the second device displays the first connection code. If the second device receives the second connection code, the second device displays the second connection code. When subsequent users input the first or second connection code to the first device, the first device may send a connection request to the second device through LAN or WAN, enabling the second device to connect to the first device. In the implementation example of the present disclosure, the second device only needs to display a connection code to connect the first device to the second device through LAN or WAN, which can be compatible with network environments of both LAN and WAN. The user only needs to obtain one connection code during usage process, eliminating the need to obtain different connection codes for repetitive connection operations. When the first or second connection code is displayed, the connection operations performed by users on the first device remains the same, and the user does not need to learn different operations for different connection codes, reducing learning and operation costs of the user.
As shown in
Step 201, generating a first connection code based on device information, and sending the first connection code and a request for a second connection code to a server. This allows the server to associate and store the first connection code and the second connection code. The first connection code is used as at least one of a verification code or an address code for a local area network, and the second connection code is used as a verification code for a wide area network.
Step 202, receiving the second connection code returned by the server.
In this embodiment, when the server 30 receives a request for a second connection code sent by the second device 20, the server 30 generates a second connection code, saves the second connection code and the first connection code in association, and sends the second connection code to the second device 20, allowing the second device 20 receives the second connection code returned by the server 30.
Step 203, displaying the second connection code, so that the connection request sent by the first device through LAN or WAN is received, where the connection request is generated by the first device based on the first or second connection code.
After the second connection code is received, the second device 20 displays the second connection code to enable the user to input the second connection code into the first device 10. After the input second connection code is received, the first device 10 sends a connection request through LAN or WAN. The connection request is generated by the first device 10 based on the first or second connection code. Specifically, in one embodiment, after the second device 20 displays the second connection code, the user inputs the second connection code displayed by the second device 20 into the first device 10. The first device 10 parses the input connection code. Upon confirming that the second connection code is the second connection code for WAN, the first device 10 retrieves the first connection code associated with the second connection code from the server 30. Based on the first connection code, the first device 10 generates a first connection request and sends the first connection request to the second device 20 through LAN. If the first device 10 fails to connect to the second device 20 through LAN, the first device 10 further generates a second connection request based on the second connection code and sends the second connection request to the second device 20 through WAN, thereby establishing a connection with the second device 20 through the WAN.
Step 204, in response to the connection request, connecting to the first device through the local area network or wide area network.
As mentioned above, after the first connection code is generated, the second device uploads the first connection code to the server and sends a request for a second connection code. After the second connection code returned by the server is received, the second device displays the second connection code, so that subsequent users may input the second connection code on the first device. The first device may acquire the first connection code associated with the second connection code from the server, so that the second device is connected through LAN or WAN. The second connection code can be compatible with network environments of both LAN and WAN. The user only needs to input the second connection code into the first device during use. In different network environments, the connection operations performed by users on the first device are the same, and the user does not need to learn different operations based on the network environment, reducing learning and operational costs of the user.
It should be further noted that in this embodiment, the second connection code is a connection code that includes at least six characters.
In this embodiment, the second connection code and the first connection code are the same, both of which are assumed to include a six-character connection code, providing a 30-bit binary encoding space. However, the second connection code may be extended to 7 or more characters depending on the actual situation. For example, when IPv4 address of the first device 10 is unique and does not belong to Class A, Class B, or Class C private segment addresses, meaning the IP address is not within the range of 10.0.0.0˜10.55.255.255.255, 172.16.0.0˜172.31.255.255, 192.168.0.0˜192.168.255.255, but is a public IP address (commonly used by overseas users, such as 202.102.34.128), the combination of six digits and letters in the second connection code mentioned above cannot be used. In such cases, the second connection code may be extended to an eight-character combination of numbers and letters. The encoding space of the second connection code is 328=240, providing 40 bits of binary encoding spaces. As compared with the second connection code composed of six characters, it expands the encoding space and can encode IPv4 addresses worldwide.
On the basis of the above embodiments, the second connection code includes a Type bit, a Parity bit, and a random bit. The Type bit is used to store the type of the LAN IP segment that is associated with the bit length of the parity bit. The Parity bit is used to store the data parity result that is not equal to the parity result of at least one data in the random bit. The random bit is used to store the random number.
In the first connection code, regardless of whether the type of LAN IP segment is Class A private segment address, Class B private segment address, or Class C private segment address, the data in the Parity bit may be equal to the parity result of the specific data in the first connection code. The specific data is a portion or all of the remaining bits in the first connection code. If the Parity bit is not equal to the parity result of a specific data, the encoding space of the 30-bit binary has not been used. Therefore, the encoding space of the 30-bit binary that is not equal to the parity result of a specific data may be used as the second connection code. Specifically, the second connection code includes Type bits, Parity bits, and random bits. The Type bits are used to store the type of LAN IP segment that is associated with the bit length of parity bits. When the type of the LAN IP segment is a Class A private segment address, the Parity bits are bits 27-26. When the type of the LAN IP segment is a Class B private segment address, the Parity bits are bits 27-25. When the type of the LAN IP segment is a Class C private segment address or a reserved extension segment, the Parity bits are bits 27-22. The random bits of the second connection code are used to store random numbers generated by the server 30. Specifically, when the second connection code is a Class A private segment address, the random bit are bits 25-0, which means that the port and IP address information are filled with random numbers. When the second connection code is a Class B private segment address, the random bits are bits 24-0, which means that random numbers are filled with the change bit, port, and IP address information. When the second connection code is a Class C private segment address, the random bits are bits 21-0, which means that random numbers are filled with the change bit, port, and IP address information. When the second connection code is a reserved extension segment, the encoding space of the 30-bit binary of the second connection code is shown in Table 5, and the random bits are bits 21-0, that is, the reserved bits are filled with random numbers.
As mentioned above, there are four situations in the encoding space of the 30-bit binary of the second connection code. However, in either case, the data parity result in the parity bit of the second connection code is not equal to the parity result of at least one random bit, so that the first connection code is distinguished from the second connection code. When the first device receives a connection code, it can determine whether the received code is the first connection code, or the second connection code based on the data verification result in the first connection code. Furthermore, the encoding method of the second connection code mentioned above allows for the widest possible range of variations in the second connection code. Specifically, for different types of LAN IP segments, the following situations exist:
For Class A private segment address: the random bit varies within the range of binary bits [0-25], multiplied by three cases where the verification fails, that is 226×(22-1)=201326492, resulting in approximately 200 million cases.
For Class B private segment address: the random bit varies within the range of binary bits [0-24], multiplied by 7 cases where the verification fails, that is 225×(23-1)=234881024, resulting in approximately 230 million cases.
For Class C private segment address: the random bit varies within the range of binary bits [0-21], multiplied by 63 cases where the verification fails, that is 222×(26-1)=264241152, resulting in approximately 260 million cases.
For reserved extension segment: the range of random bits varies within the range of binary bits [0-21], multiplied by 63 cases where the verification fails, that is 222×(26-1)=264241152, resulting in approximately 260 million cases.
There are a total of 965 million possible changes in the second connection code. Even with one million devices online, it would only occupy one thousandth of the total amount, meeting the practical usage requirements.
As mentioned above, the embodiment of the present disclosure extends the encoding space of the first connection code where the parity bit is not equal to the parity result of specific data to the second connection code, so that the server has a large range of changes in the second connection code during the generation process of the second connection code, which ensures the uniqueness of the second connection code, thereby avoiding security issues caused by unintentional or malicious exhaustion. Furthermore, the presentation form of the second and first connection codes is unified, both presented in the form of characters, and the second and first connection codes only need a minimum of six characters, making user input simple and convenient, thus improving the user experience.
As shown in
Step 301, receiving a first connection code or a second connection code, where the first connection code is used as at least one of a verification code or an address code for a local area network, and the second connection code is used as a verification code for a wide area network.
After the first or second connection code is displayed in the second device 20, the user inputs the first or second connection code on the second device 20 into the first device. For example, the first device 10 is equipped with a software application for device connection, and after the user opens the software application, the software interface of the software application may prompt the user to input the connection code. For example, the first device 10 displays an input box on the screen for the user to input the connection code. When the second device 20 displays the second connection code, the user inputs the second connection code in the software interface of the first device 10. When the second device 20 displays the first connection code, the user inputs the first connection code in the software interface of the first device 10.
Step 302, when the second connection code is received, requesting the server to send the first connection code associated with the second connection code.
After the connection code is received, the first device 10 first determines whether the connection code is the first or second connection code. Specifically, after the connection code is received, the first device 10 first obtains the Type bit of the connection code and determines the type of LAN IP segment corresponding to the connection code. Then, based on the correlation between the type of LAN IP segment and the length of the parity bit, the length of the Parity bit can be confirmed to obtain the parity result from the parity bit. Then, it is further determined whether the parity result is equal to the parity result of at least one data in other bits. If it matches, the connection code is identified as the first connection code; otherwise, the connection code is identified as the second connection code. For example, in one embodiment, the first device 10 first obtains the bit 29-28 of the connection code, which is the Type bit of the connection code, and determines the type of LAN IP segment corresponding to the connection code. When the bit 29-28 of the connection code is 00, the type of LAN IP segment corresponding to the connection code is Class A private segment address, and obtains the bit 27-26 of the connection code, which is the Parity bit. It is determined whether the data parity result of the Parity bit is equal to the parity result of at least one of the other bits. If so, the connection code is the first connection code; if not, the connection code is the second connection code. The same process applies to other situations, and a specific process is shown in
In this embodiment, when the first device 10 confirms that the received connection code is the second connection code, it accesses the server 30 and sends a request for receiving the first connection code associated with the second connection code to the server 30. After the request is received, the server 30 queries the associated first connection code based on the second connection code and sends the first connection code to the first device 10. For example, in one embodiment, the first device 10 sends a request to query the information of the second device to the server 30 based on the second connection code after the second connection code is received. The server 30 queries the information of the second device based on the second connection code after the request is received, obtains the first connection code associated with the second connection code, and sends the first connection code to the first device 10.
Step 303, based on the first connection code, sending a first connection request to the second device through the local area network.
After the first connection code is received, the first device 10 parses the verification information and IP address information of the second device 20 from the first connection code, generates a first connection request based on the verification information and IP address information, and sends the first connection request to the second device 20 through LAN to establish a connection with the second device 20 through LAN.
Step 304, when the first connection code is received and connection establishment corresponding to the first connection request fails, requesting the server to send the second connection code associated with the first connection code.
If the user inputs a connection code in the first device 10 and the first device 10 determines that the connection code is the first connection code, a first connection request is generated based on the first connection code, and a first connection request is sent to the second device 20 through LAN to establish a connection with the second device 20 through LAN. If the LAN connection between the first device 10 and the second device 20 fails, the first device 10 further sends a second connection code to the server 30 for receiving the second connection code associated with the first connection code. The process of requesting a second connection code by the first device 10 is similar to the process of requesting a first connection code. The specific process may be referred to in step 303 and will not be repeated in this embodiment.
Step 305, after confirming that the connection establishment corresponding to the first connection request fails, sending a second connection request to the second device through the wide area network based on the second connection code.
In Step 304 or Step 305, after the first device 10 sends a first connection request to the second device 20 through LAN, if the first device 10 and the second device 20 fail to connect through LAN, the first device 10 confirms that the connection establishment corresponding to the first connection request has fails, further parses the verification information from the second connection code, and generates a second connection request based on the verification information, and sends a second connection request to the second device 20 through WAN to establish a connection with the second device 20 through WAN.
For example, in the scenario shown in
In one embodiment, as shown in
In another embodiment, as shown in
After the first device 10 and the second device 20 are connected through WAN or LAN, screen projection may be carried out between the first device 10 and the second device 20. For example, the first device 10 sends video data containing image displayed on the current screen and audio data for playing sound to the second device 20 through LAN or WAN. After video data and audio data are received, the second device 20 decodes video and audio data, displays corresponding images and plays corresponding sounds on the screen.
As mentioned above, in the embodiment of the present disclosure, the first device first determines the type of connection code after the connection code input by the user is received. If the connection code input by the user is the first connection code, the second device is connected to through LAN. If the connection fails, the second connection code associated with the first connection code is further obtained from the server and connected to the second device through WAN. If the connection code input by the user is the second connection code, the first connection code associated with the second connection code is obtained from the server. First, the connection is made to the second device through LAN. If the connection fails, the connection is further made to the second device through WAN. The first device in the embodiment of the present disclosure can connect to the server through LAN or WAN after the first or second connection code is received, thereby being compatible with the network environment of LAN or WAN. Secondly, if the first device cannot connect to the second device through LAN, it can automatically switch to connect to the second device through WAN, avoiding the situation where the first device cannot connect to LAN, which greatly improves the connection success rate. In addition, taking into consideration the high bandwidth, low latency, and absence of internet traffic fees in the LAN, the first device prioritizes connecting to the second device through LAN when receiving either the first or second connection code. When the connection fails through LAN, it switches to WAN for connection, which can improve the security of information exchange and avoid unnecessary traffic costs.
In another embodiment, when the first device 10 and the second device 20 are connected to LAN and not to WAN, the connection process between the first device 10 and the second device 20 is shown in
In one embodiment, the second connection code is associated with service information.
Service information refers to information that includes service functions and service data. In this embodiment, as the WAN connection code is used as a verification code and does not have service attributes, in one embodiment, the second device 20 may also upload service information to the server 30, enabling the server 30 to associate the service information with the second connection code, so that it may perform the corresponding service function when it receives the second connection code and successfully connects with the second device 20. In one embodiment, the second connection code may be associated with multiple service information, so that the first device 10 may achieve different service functions after inputting the second connection code, thereby unifying all scalable service functions through a second connection code.
Correspondingly, the method for connecting devices further includes:
After confirming that the second connection code is received and the connection establishment corresponding to the first or second connection request succeeds, performing a service action corresponding to the service information.
In one embodiment, when the first device 10 receives the second connection code and successfully connects to the second device 20 through LAN or WAN, the first device 10 is further used to perform service actions corresponding to the service information associated with the second connection code. Service actions refer to the operations and means used to execute service functions. For example, in one embodiment, the second device 20 applies for a second connection code DXD5AG from the server 30, and the second device 20 further runs video conferencing software. Video conferencing software refers to software used to connect devices and transmit images captured by a camera on the device and sound recorded by the microphone. When a room number of the video conference is 1234567890, the room number 1234567890 may be uploaded as service data to the server 30 as service information for the second connection code DXD5AG. The server 30 associates the second connection code DXD5AG with the room number 1234567890. Afterwards, when the user inputs the second connection code DXD5AG in the video conference sub-function interface on the video conference software of the first device 10, the second device 20 is connected to the first device 10 through WAN. At the same time, the first device 10 accesses the server 30 and obtains the room number associated with the second connection code DXD5AG from the server 30. The video conferencing software on the first device 10 may be directly added to the room for video conferencing. In one embodiment, in addition to video conferencing, service information for service functions such as screen interaction or remote assistance may also be associated with a second connection code, allowing users to input the second connection code DXD5AG on other sub-functional interfaces of the video conferencing software on the first device 10, and also achieve corresponding screen interaction or remote assistance functions. Screen interaction function refers to the function of controlling images displayed on the screens of two interconnected devices, and remote assistance function refers to the function that one of two interconnected devices can control the other device.
As mentioned above, the embodiment of the present disclosure associates the second connection code with service information, so that the second device can perform service actions associated with the service information after the second connection code is received and the first device is successfully connected to. During this process, the user does not need to perform additional operations, which expands the function of the connection code and improves the user experience.
