DETAILED DESCRIPTION

In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

FIG1 is a flowchart of a method for wirelessly connecting a PC and a terminal shown in Embodiment 1 of the present application.

The method for connecting a PC and a terminal applied to a PC client according to the first embodiment of the present application includes the following steps:

S102, confirming the existence of an associated terminal client in the local area network based on the detection data packet;

S104, obtaining terminal information of the associated terminal client;

S106 , triggering the PC to wirelessly connect to the terminal according to the terminal information.

Those skilled in the art will understand that a PC client is a client installed on a PC, while a terminal client is a client installed on a terminal. A terminal client can be installed on a mobile terminal capable of accessing a wireless local area network, such as a mobile phone or tablet computer. Terminal information is information used to identify the mobile terminal.

The PC client's local LAN refers to the LAN to which the PC is currently connected; the presence of an associated terminal client within the LAN means that the terminal to which the associated terminal client belongs is connected to the LAN. In specific implementations, the PC can access the LAN wirelessly or via a wired connection; the terminal typically accesses the LAN wirelessly. Those skilled in the art will appreciate that to achieve a wireless connection between the PC and the terminal, both the PC and the terminal must include a wireless communication module, such as a wireless network card.

In a specific implementation, the association relationship between the terminal client and the PC client can be established by the terminal where the terminal client is located and the PC where the PC client is located being successfully connected wired or wirelessly within a predetermined time, the terminal client and the PC client being logged into the same account, or the terminal client and the PC client being logged into different accounts belonging to the same user; those skilled in the art should understand that as long as the terminal client and the PC client can be associated and an association relationship between them can be established on the terminal client and the PC client. More specifically, those skilled in the art can establish an association relationship between the terminal client and the PC client by recording the unique identifier of the most recently successfully connected terminal/PC on the PC client/terminal client. To avoid confusion, usually within a local area network, a PC client is associated with only one terminal client. Preferably, the wireless connection method between the PC and the terminal is a WIFI (Wireless-Fidelity) connection.

Wi-Fi speeds vary depending on the wireless network card standard used. IEEE802.11b has a maximum speed of 11 Mbps, IEEE802.11a has a maximum speed of 54 Mbps, and IEEE802.11g also has a maximum speed of 54 Mbps. Netgear SUPER g technology can increase the speed to 108 Mbps.

In specific implementation, the PC and the terminal may also be connected by a wireless method such as WAPI (Wireless LAN Authentication and Privacy Infrastructure).

Therefore, users can connect the PC and the terminal wirelessly through WIFI or WAPI, which enables users to experience the high data transmission rate between the PC and the terminal conveniently and quickly without relying on USB cables.

By adopting the method for connecting a PC and a terminal in an embodiment of the present application, after confirming that the associated PC and the terminal are in the same local area network according to the detection data packet and the PC obtains the information of the terminal, the PC is triggered to be wirelessly connected to the terminal; this avoids the reliance on a USB cable when connecting the PC and the terminal in the prior art, making the connection between the PC and the terminal more convenient and quick, and improving the user experience.

In the existing method of connecting a PC to a terminal, the user needs to first start the PC client, and then click on the main interface of the PC client to enter the mobile phone connection interface. After entering the mobile phone connection interface, the PC client triggers the PC to scan whether there is a mobile phone with a mobile assistant terminal client installed in the local area network of the PC; if there is, it is listed, and the user confirms the mobile phone associated with his or her PC client from the listed mobile phone list, and then the PC client performs subsequent operations to connect the PC wirelessly to the mobile phone.

With the solution in the prior art, the user selects the mobile phone associated with the PC client. If there are multiple mobile phones with the mobile assistant terminal client installed in the local area network, it will take the user several seconds to find the mobile phone they want to connect to, resulting in a poor user experience.

Optionally, based on the detection data packet, confirming the existence of an associated terminal client in the local local area network specifically includes: the PC client sends a first detection data packet in the local local area network; when receiving first response data from the associated terminal client in the local local area network to the first detection data packet, confirming the existence of an associated terminal client in the local local area network, wherein the first response data carries terminal information; obtaining the terminal information of the terminal client specifically includes: extracting the terminal information from the first response data.

If there is no terminal client associated with the PC client in the local area network, the PC client may send the detection data packet again after a predetermined time interval, or may not send the detection data packet again. This application does not impose any restrictions on this.

In a specific implementation, the first probe data packet and the first response data packet may be UDP (User Datagram Protocol) data packets; the PC client may send the first probe data packet in a multicast manner within the local area network, or may send it in a broadcast manner. It should be understood that the above examples are provided for the purpose of facilitating the implementation of the present application by those skilled in the art and are not intended to limit the present application.

Those skilled in the art should understand that in order to enable the PC or terminal that receives the first detection data packet to identify and return response data, the first detection data packet sent by the PC client carries the unique identifier of the PC client in the local area network. The unique identifier can be the IP address of the PC or the unique identifier assigned to the PC client by the server, such as a randomly generated 32-bit GUID (Globally Unique Identifier): 2cf2ecc8-166d-43ce-8759-38735f842211, etc.

In a specific implementation, the terminal client can determine whether the PC client is an associated PC client based on the first probe packet in the following manner: upon receiving the first probe packet, the terminal client extracts the PC identifier from the probe packet and compares the identifier with the identifier of the associated PC stored by the terminal client. If the identifiers match, the PC client that sent the first probe packet is determined to be an associated PC client; if the identifiers do not match, the PC client is deemed not to be an associated PC client. It should be understood that the above examples are provided to facilitate implementation of the present application by persons skilled in the art and are not intended to limit the present application.

By adopting the method in the embodiment of the present application, the PC client sends a network detection packet in the local area network, and the associated terminal client replies with response data, so that the PC client can automatically confirm the terminal client associated with it. This process does not require user participation, reduces user operations, and improves user experience.

Preferably, the PC client starts triggering the PC client to send a first detection data packet in the local area network. When the present application is specifically implemented, the PC client can also send the first detection data packet after starting up and detecting that the PC has been connected to the local area network, or can send the first detection data packet at any other preset time.

By adopting the solution in the embodiment of the present application, the PC client immediately triggers the sending of the first detection data packet within the local area network after startup. After the user starts the PC client, the process of connecting to the terminal can be immediately initiated without the user having to perform further operations, thereby improving the user experience.

Optionally, confirming the existence of an associated terminal client in the local local area network based on the detection data packet specifically includes: receiving a second detection data packet, wherein the second detection data packet is sent by the terminal client in the local local area network; judging whether the terminal client is associated with the terminal client based on the second detection data packet, and if so, confirming the existence of an associated terminal client in the local local area network; obtaining the terminal information of the terminal client specifically includes: sending second response data for the second detection data packet to the associated terminal client; and receiving the terminal information sent by the terminal client.

In a specific implementation, the second probe data packet and the second response data can be UDP (User Datagram Protocol) data packets; the second probe data packet can be sent in a multicast manner within the local area network, or can be sent in a broadcast manner. It should be understood that the above examples are provided for the purpose of facilitating the implementation of the present application by those skilled in the art and are not intended to limit the present application.

Those skilled in the art should understand that in order to enable the PC or terminal that receives the second detection data packet to identify and return response data, the second detection data packet sent by the terminal client carries the unique identifier of the terminal client in the local area network. The unique identifier can be the IP address of the terminal or the unique identifier assigned to the terminal client by the server, such as the terminal client connection code: GK5R9K, etc.

In a specific implementation, the PC client can determine whether the terminal client is an associated terminal client based on the second probe packet in the following manner: when the PC client receives the second probe packet, it extracts the identifier of the sending terminal from the probe packet and compares the identifier with the identifier of the associated terminal stored on the PC client. If the identifiers match, the terminal client that sent the second probe packet is determined to be an associated terminal client; if the identifiers do not match, the terminal client is deemed not to be an associated terminal client. It should be understood that the above examples are provided for the purpose of facilitating the implementation of the present application by persons skilled in the art and are not intended to limit the present application.

By using the method in the embodiment of the present application, when the PC client receives the second detection data packet, it determines the existence of an associated terminal client based on the content carried in the data packet, so that the PC client can automatically confirm the terminal client associated with it. This process does not require user participation, reduces user operations, and improves user experience.

In the prior art, when the user's PC or terminal does not have a WIFI environment, the connection between the terminal and the PC cannot be achieved, causing inconvenience to the user.

Optionally, before confirming the existence of the associated terminal client in the local area network according to the detection data packet, the method further includes: the PC client triggering the PC to establish a WIFI hotspot, and the terminal is connected to the local area network through the hotspot.

The PC can establish a WIFI hotspot (soft AP) through a wireless network card, allowing the terminal and PC to access the same local area network, thereby realizing the connection between the terminal and the PC and improving the user experience.

Optionally, before confirming the existence of an associated terminal client in the local area network according to the detection data packet, the method further includes: the terminal client triggering the terminal to establish a WIFI hotspot, and the PC is connected to the local area network through the hotspot.

The terminal can establish a WIFI hotspot through the wireless network card, allowing the terminal and PC to access the same local area network, thereby realizing the connection between the terminal and the PC and improving the user experience.

Preferably, before confirming the existence of an associated terminal client in the local area network based on the detection data packet, it also includes: prompting on the PC screen or the terminal screen whether to connect the PC and the terminal; triggering the PC to wirelessly connect to the terminal according to the terminal information specifically includes: when the user confirms the connection, triggering the PC to wirelessly connect to the terminal according to the terminal information.

In specific implementation, there are many ways to prompt on the PC screen or terminal screen whether the connection to the terminal is made, for example, a prompt box pops up in the lower right corner of the PC screen; a prompt box pops up in the middle of the PC screen; a prompt box flashes in the lower right corner of the PC and pops up after the user clicks it; a prompt box pops up in the middle of the terminal screen, etc.; those skilled in the art should understand that as long as the user can be prompted, the above methods are only examples and are not used to limit this application.

If the user chooses not to connect, the prompt box is closed; or if the user does not click the selection button, the prompt box is automatically closed after a predetermined time, for example, 10 seconds.

Taking the Wi-Fi connection process between a PC and a mobile phone connected to the same wireless LAN as an example, after the PC is turned on and connected to the wireless LAN and automatically logs in to the PC client, the PC client discovers that the user's mobile phone is also connected to the same wireless LAN; the PC obtains relevant information about the mobile phone; then the PC client pops up a prompt box and asks the user "Do you want to connect your mobile phone?" If the user clicks "Yes", the PC client triggers the PC to start the wireless communication module and connect to the mobile phone via Wi-Fi; if the user clicks "No", the PC client closes the prompt box; or if the user does not click the prompt button, the prompt box automatically closes after 10 seconds.

By adopting the solution in the embodiment of the present application, when the PC client finds an associated terminal client connected to the same local area network, the terminal client or the PC client is triggered to ask the user whether to connect, and wirelessly connect/not connect according to the user's choice; the choice of whether to connect the PC and the terminal is given to the user, avoiding unnecessary resource consumption caused by connecting the PC and the terminal when the user does not need it, saving resources, and improving the user experience.

In the conventional method of connecting a PC to a terminal, after a user confirms a mobile phone associated with his/her PC client from a list of listed mobile phones, the PC obtains the mobile phone information of the mobile phone and then wirelessly connects to the mobile phone.

With the solution in the existing technology, after the user confirms the connection, the PC will try to obtain the terminal information again. Even if the acquisition is successful, there will be a certain delay. If the acquisition fails, the connection will also be unsuccessful, which is inconsistent with the user's expectations and will lead to a decline in user experience.

Preferably, the terminal information includes the terminal IP address and port number. In the specific implementation of this application, the terminal information may further include other terminal information such as the terminal name, user mobile phone number, etc.

By adopting the solution in the embodiment of the present application, the IP address and port number of the terminal information have been obtained before asking the user whether to connect to the terminal, preparing for the subsequent wireless connection. Once the user confirms the connection, it can be quickly connected to the terminal, avoiding the delay caused by obtaining the terminal information after the user confirms the connection, and also improving the connection success rate after the user confirms the connection, thereby improving the user experience.

FIG2 is a flow chart of a method for connecting a PC and a terminal according to a second embodiment of the present application.

As shown in FIG2 , the method for connecting a PC and a terminal applied to a terminal client according to the second embodiment of the present application includes the following steps:

S202, confirming the existence of an associated PC client in the local area network based on the detection data packet;

S204, sending terminal information to the associated PC client;

S206 , triggering the terminal to accept the wireless connection establishment request sent by the PC according to the terminal information, so as to establish a wireless connection with the PC.

Those skilled in the art will understand that a terminal client is a client installed on a terminal, and a PC client is a client installed on a PC. A terminal client can be installed on a mobile terminal capable of accessing a wireless local area network, such as a mobile phone or tablet computer. Terminal information is information used to identify the mobile terminal.

The PC client's local LAN refers to the LAN to which the PC is currently connected; the presence of an associated terminal client within the LAN means that the terminal to which the associated terminal client belongs is connected to the LAN. In specific implementations, the PC can access the LAN wirelessly or via a wired connection; the terminal typically accesses the LAN wirelessly. Those skilled in the art will appreciate that to achieve a wireless connection between the PC and the terminal, both the PC and the terminal must include a wireless communication module, such as a wireless network card.

In specific implementations, the association between a terminal client and a PC client can be established by successfully connecting the terminal where the terminal client resides to the PC where the PC client resides, either wired or wirelessly, within a predetermined timeframe, or by logging into the same account as the terminal client and the PC client, or logging into different accounts belonging to the same user. Those skilled in the art will appreciate that as long as the terminal client and the PC client can be associated and an association established between them, it will suffice. More specifically, those skilled in the art can establish the association between the terminal client and the PC client by recording the unique identifier of the most recently successfully connected terminal/PC on the PC client/terminal client. To avoid confusion, typically within a local area network, a PC client is associated with only one terminal client.

Preferably, the wireless connection establishment request received by the terminal is a WIFI connection establishment request.

During specific implementation, the PC and the terminal may also be connected using a wireless method such as WAPI.

Therefore, users can connect the PC and the terminal via WIFI, which enables users to experience the high data transmission rate between the PC and the terminal conveniently and quickly without relying on USB cables.

Taking the Wi-Fi connection process between a PC and a mobile phone connected to the same wireless LAN as an example, after the mobile phone is turned on and connected to the wireless LAN and automatically logs in to the terminal client, the terminal client discovers that the user's PC is also connected to the same wireless LAN; the terminal client sends mobile phone related information to the PC client; waits for the PC to send a wireless connection establishment request; if the request is received, it is accepted; if not, no processing is performed.

By adopting the method for connecting a PC and a terminal in an embodiment of the present application, when it is confirmed based on a detection data packet that the associated PC and the terminal are in the same local area network, the terminal sends terminal information to the PC, and then accepts a wireless connection establishment request sent by the PC to establish a wireless connection between the terminal and the PC; this avoids the reliance on a USB cable when connecting the PC and the terminal in the prior art, making the connection between the PC and the terminal more convenient and quick, and improving the user experience.

In the existing method of connecting a PC and a terminal, if a user wants to trigger a wireless connection between the PC and the terminal from the terminal side, the user needs to open the main interface of the PC client, then enter the QR code connection interface, generate a QR code, and open the QR code scanning tool of the terminal at the same time to scan the QR code. After the scanning is completed, the terminal requests the PC to establish a wireless connection, thereby completing the wireless connection between the PC and the terminal.

With the solution in the existing technology, users need to open the PC client and the terminal client at the same time, click multiple times, and then scan the QR code to connect. The operation is cumbersome and difficult to complete smoothly for users who are not familiar with smart terminals.

By adopting the technical solution of the embodiment of the present application, when the terminal client confirms that there is an associated PC client in the local area network, it sends terminal information to the PC client, triggering the PC side to initiate a wireless connection request. In this process, the user can complete the wireless connection between the PC and the terminal without any operation, which is convenient and fast, and improves the user experience.

Optionally, confirming the existence of an associated PC client in the local LAN based on the detection data packet specifically includes: receiving a first detection data packet, wherein the first detection data packet is sent by the PC client in the local LAN; determining whether the PC client is associated with the PC client based on the first detection data packet; if so, confirming the existence of an associated PC client in the local LAN; sending terminal information to the associated PC client specifically includes: sending first response data to the associated PC client, the first response data carrying terminal information.

In a specific implementation, the first probe data packet and the first response data packet may be UDP data packets; the first probe data packet may be sent in a multicast manner within the local area network, or may be sent in a broadcast manner. It should be understood that the above examples are provided to facilitate those skilled in the art in implementing the present application and are not intended to limit the present application.

Those skilled in the art should understand that in order to enable the PC or terminal that receives the first detection data packet to identify and return response data, the first detection data packet sent by the PC client carries a unique identifier of the PC client in the local area network. The unique identifier can be the IP address of the PC or a unique identifier assigned to the PC client by the server, such as a randomly generated 32-bit GUID: 2cf2ecc8-166d-43ce-8759-38735f842211, etc.

In a specific implementation, the terminal client can determine whether the PC client is an associated PC client based on the first probe packet in the following manner: upon receiving the first probe packet, the terminal client extracts the identifier of the sending PC from the probe packet and compares the identifier with the identifier of the associated PC stored by the terminal client. If the identifiers match, the PC client that sent the first probe packet is determined to be an associated PC client; if the identifiers do not match, the PC client is deemed not to be an associated PC client.

This process does not require user participation, reduces user operations, and improves user experience.

Optionally, confirming the existence of the associated PC client in the local area network according to the detection data packet specifically includes: sending a second detection data packet in the local area network; and confirming the existence of the associated PC client in the local area network when receiving second response data from the associated PC client in response to the second detection data packet.

If there is no PC client associated with the terminal client in the local area network, the terminal client may send the detection data packet again after a predetermined time interval, or may not send the detection data packet at all. This application does not impose any restrictions on this.

In a specific implementation, the second probe data packet and the second response data can be UDP data packets; the terminal client can send the second probe data packet in the local area network in a multicast manner or in a broadcast manner. It should be understood that the above examples are provided for the purpose of facilitating the implementation of the present application by those skilled in the art and are not intended to limit the present application.

It should be understood that the above examples are provided for the purpose of facilitating the implementation of the present application by persons skilled in the art and are not intended to limit the present application.

Using the method in the embodiment of the present application, the terminal client sends a second detection data packet within the local area network; when receiving second response data from the associated PC client in response to the second detection data packet, it confirms that the associated PC client exists in the local area network; then, terminal information is sent to the associated PC client to trigger the PC client to ask the user whether to connect; so that the terminal client can automatically confirm the PC client associated with it and trigger the PC client to ask the user whether to connect. This process does not require user participation, reduces user operations, and improves user experience.

Preferably, the terminal is connected to the local area network triggering the terminal client to send the second detection data packet in the local area network. When the present application is implemented, the terminal client can send the second detection data packet in the local area network immediately after startup, or immediately when the terminal starts the WIFI connection, or at any other preset time.

By adopting the solution in the embodiment of the present application, the terminal client immediately triggers the sending of a second detection data packet within the local area network after connecting to the local area network. After the user connects to the local area network, the process of connecting to the terminal can be initiated immediately without the user having to perform more operations, thereby improving the user experience.

Optionally, based on the detection data packet, confirming the existence of an associated PC client in the local area network specifically includes: obtaining the IP address of a PC that has successfully connected within a predetermined time from the server; sending a third detection data packet to the IP address; when receiving third response data for the third detection data packet, confirming the existence of an associated PC client in the local area network; sending terminal information to the associated PC client specifically includes: sending the terminal information to the PC client corresponding to the IP address that sends the third response data.

If the third response data is not received, it is determined that there is no PC client connected within the predetermined time locally.

During specific implementation, the terminal client may send the third detection data packet via wireless means such as WIFI or WAPI.

The IP address obtained by the terminal client from the server can be one, multiple, or none. If there are multiple IP addresses, the terminal client can send probe packets to these IP addresses in sequence. If the IP address is not in the local area network, the probe packet will not be received by the terminal client, so the terminal client will not receive the response packet from the IP address. If a response packet is received, it is confirmed that the PC is in the local area network.

The terminal client can obtain the scheduled time from the server immediately after startup, such as the IP address list of PCs that have successfully connected within 24 hours, or obtain it from the server immediately when starting WIFI, or obtain it from the server at any other preset time. This application does not impose any restrictions on this.

Using the method in the embodiment of the present application, after the terminal client obtains the IP address of a PC that has been successfully connected within a predetermined time from the server, it sends a third detection data packet to the IP address; when receiving the third response data for the third detection data packet, it confirms that there is an associated PC client in the local area network; then, terminal information is sent to the PC client corresponding to the IP address that sent the third response data, triggering the PC client to initiate a connection request; this process does not require user participation, reduces user operations, and improves user experience.
