[0051] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0052] The network connection method provided in the present disclosure is applied to a scenario where a network connection is performed between electronic devices, for example, it is applied to a scenario where electronic devices perform a WLAN direct connection.

[0053] With the development of science and technology, electronic devices have become widely popular, and more and more users use electronic devices to handle various affairs in daily life and work. And with the development of electronic device technology and people's growing demand for use, the functions of electronic devices are also constantly improving. For example, in order to realize data transmission between electronic devices, a related WLAN direct connection protocol has been introduced. The WLAN direct connection protocol can realize data transmission between devices, that is, through point-to-point direct connection technology (Peer-to-Peer, P2P) or through software (Soft) on electronic devices to achieve wireless access point (Access Point, AP) function to realize point-to-point direct connection technology (SoftAp-P2P), and then data transmission between devices can be realized.

[0054] The scenario of data interaction between devices supporting P2P technology (P2P Device) through WLAN direct connection can be understood as data interaction between multiple devices based on the same Wireless Fidelity (Wi-Fi). P2P direct connection technology can be applied between electronic devices. The device that provides a wireless access point (AP) for other devices can be used as an access point (P2P Group Owner, GO), and the other end device connected to the GO device can be used as a site (P2P Client, GC), and a P2P group (P2P Group) is established to transmit data between electronic devices in the P2P group. In addition, P2P technology also includes SoftAp-P2P direct connection technology. SoftAp-P2P direct connection technology can be applied between electronic devices and personal computers (Personal Computer, PC). The PC starts a soft AP (Soft AP) as the CO end in P2P, and the electronic device as the GC end can be connected to the PC, thereby establishing a P2P group and realizing data interaction.

[0055] In the related art, after a P2P group is established, the GC end and the GO end in the P2P group will always remain connected unless the user actively requests to disconnect. When there is less business data for interaction in the P2P group, the devices at both ends will still interact by regularly sending and receiving beacon frames, resulting in excessive power consumption. Therefore, the P2P connection can be disconnected when it is detected that the data flow in the P2P is lower than the threshold for a long time, thereby reducing power consumption losses. However, when the P2P connection is disconnected, when the device detects that it needs to connect again, it still needs to perform a series of actions such as P2P device discovery, role negotiation, and connection, which takes a long time.

[0056] Therefore, the present disclosure saves the network configuration of the network to which the first device and the second device are connected. When the network connection between the first device and the second device is disconnected and a data transmission request is detected, the network connection between the first device and the second device can be quickly restored according to the saved network configuration, thereby improving the network reconnection speed between the devices.

[0057] Figure 1 is a flow chart of a network connection method according to an exemplary embodiment. Figure 1 As shown, the network connection method is used in a terminal and includes the following steps.

[0058] In step S11 , in response to the first device establishing a network connection with the second device, a network configuration of the network connected to the second device is saved.

[0059] In the implementation of the present disclosure, the network connection established between the first device and the second device may be a peer-to-peer (P2P) network connection established based on WLAN direct connection technology.

[0060] In the implementation of the present disclosure, the first device may be a device for providing a wireless connection in a P2P direct connection, and the second device may be a device for receiving a message in a P2P direct connection.

[0061] In the embodiment of the present disclosure, the first device saves the network configuration connected to the second device, which may be network configuration information such as role, channel, service set identifier (SSID), address resolution protocol (ARP), and static Internet Protocol address (IP).

[0062] In step S12, in response to the first device disconnecting the network connected to the second device and detecting a data transmission request, the network connection with the second device is restored based on the saved network configuration.

[0063] The data transmission request is used to request data transmission to the second device.

[0064] In the embodiment of the present disclosure, the first device disconnects from the connected network with the second device, and the first device detects a data transmission request and restores the network connection with the second device based on the saved network configuration.

[0065] In the embodiment of the present disclosure, when the first device establishes a network connection with the second device through the WLAN direct connection technology, the first device saves the network configuration connected with the second device. When the network connected between the first device and the second device is disconnected, and the first device detects a data transmission request to send data to the second device, the network connection with the second device is restored based on the saved network configuration.

[0066] In the embodiment of the present disclosure, by saving the network configuration of the network to which the first device and the second device are connected, when the network connection between the first device and the second device is disconnected and a data transmission request is detected, the network connection between the first device and the second device can be quickly restored based on the saved network configuration, thereby improving the network reconnection speed between the devices.

[0067] In the embodiment of the present disclosure, the network configuration of the connected network between the first device and the second device may be represented by an identifier.

[0068] Figure 2 is a flow chart of a network connection method according to an exemplary embodiment. Figure 2 As shown, the network connection method is used in a terminal and includes the following steps.

[0069] In step S21 , in response to the first device establishing a network connection with the second device, a first identifier is generated.

[0070] The first identifier is used to identify the network configuration of the network connected between the first device and the second device.

[0071] In the embodiment of the present disclosure, the first identifier is unique to the network configuration of the network connected between the first device and the second device. For example, when the first device establishes a network connection with multiple second devices at the same time, the first device generates different first identifiers based on the network configurations of the network connections with different second devices.

[0072] In step S22, the first identifier and the network configuration are saved.

[0073] In the embodiment of the present disclosure, the first device saves the first identifier and the network configuration of the connected network corresponding to the first identifier.

[0074] In step S23, in response to the first device disconnecting the network connected to the second device and detecting a data transmission request, the network connection with the second device is restored based on the saved network configuration.

[0075] In an embodiment of the present disclosure, when the network connection between a first device and a second device is disconnected and the first device detects the presence of a data transmission request to send data to the second device, the first device determines the network configuration corresponding to the second device based on the first identifier, and restores the network connection with the second device based on the network configuration corresponding to the second device.

[0076] In the embodiment of the present disclosure, by generating a first identifier that is uniquely used to identify the network configuration of the connected network between the first device and the second device, when the network connection between the second device needs to be restored, the corresponding network configuration can be quickly obtained through the first identifier, thereby achieving rapid restoration of the network connection between the devices.

[0077] In the embodiment of the present disclosure, the first device and the second device need to restore corresponding network configurations at the same time, so that the network connection between the first device and the second device can be restored.

[0078] In the disclosed embodiment, the first identifier corresponding to the network configuration of the network connected between the second device and stored by the first device may be the same as the first identifier corresponding to the network configuration of the network connected between the first device and stored by the second device.

[0079] In the embodiment of the present disclosure, a first identifier may be generated by a first device and sent to a second device.

[0080] Figure 3 is a flow chart of a network connection method according to an exemplary embodiment. Figure 3 As shown, the network connection method is used in a terminal and includes the following steps.

[0081] In step S31, a first identifier is sent to a second device, so that the second device can query a network configuration based on the first identifier.

[0082] In the embodiment of the present disclosure, the first device sends a first identifier to the second device, wherein the first identifier may be an identifier uniquely corresponding to the network configuration between the first device and the second device. The second device may query the network configuration when the second device is connected to the first device based on the first identifier.

[0083] In the embodiment of the present disclosure, the first identifier may be a universally unique identifier (Universally Unique Identifier, UUID), for example, the first identifier may be a 32-bit UUID.

[0084] In step S32, the network configuration is queried based on the first identifier, and based on the network configuration, a network connection corresponding to the network configuration is restored with the second device.

[0085] In the embodiment of the present disclosure, the first device determines the network configuration for establishing a network connection with the second device based on the first identifier, and the second device determines the network configuration for establishing a network connection with the first device based on the first identifier. When both the first device and the second device complete the network configuration, the network connection between the first device and the second device is restored.

[0086] In the implementation of the present disclosure, by sending a first identifier to a second device, the second device can match the network configuration for the network connection with the first device with the first identifier, so that when it is necessary to restore the network connection between the first device and the second device, the network configuration for the connection between the first device and the second device can be quickly determined in the first device and the second device, thereby achieving rapid connection between the devices.

[0087] In the embodiment of the present disclosure, the first identifier may be carried in the first message.

[0088] Figure 4 is a flowchart of a network connection method based on first information according to an exemplary embodiment. Figure 4 As shown, the network connection method is used in a terminal and includes the following steps.

[0089] In step S41, a first message is sent to a second device or a first message sent by a second device is received through an out-of-band data OOB manner.

[0090] The first message includes a first type identifier.

[0091] The first type identifier is used to identify that the first message is used to restore the network connection, and the first message carries the first identifier.

[0092] In the embodiment of the present disclosure, the first message may be transmitted between the first device and the second device in an out-of-band (OOB) manner, wherein the OOB manner may be transmitted in a Bluetooth or Bluetooth Low Energy (BLE) manner.

[0093] In the implementation of the present disclosure, a first device may send a first message to a second device, wherein the first message includes a first type identifier, and the first type identifier may be used to indicate that the first message may be used to restore a network connection between the first device and the second device.

[0094] In the embodiment of the present disclosure, a first device may receive a first message sent by a second device, and the first device may determine that the first message is used to restore a network configuration between the first device and the second device based on a first type identifier in the first message, and determine a network configuration of a network connection with the second device based on a first identifier carried in the first message.

[0095] In step S42, based on the first information, a network connection corresponding to the network configuration is restored with the second device.

[0096] In an implementation of the present disclosure, the first device may determine, through a first type identifier in the first information, that the first information can be used to restore a network connection, and determine a network configuration of a network connection with the second device based on the first identifier in the first information.

[0097] In the disclosed embodiment, the message interaction between the first device and the second device is implemented in an OOB manner, thereby avoiding occupying the service transmission channel between the devices during message interaction, thereby preventing interference with normal data transmission between the devices.

[0098] In the embodiment of the present disclosure, when the data transmission volume between devices is less than the data transmission volume threshold within the first time, the network connection between the devices can be temporarily disconnected.

[0099] Figure 5 is a flow chart showing a method for temporarily disconnecting a network connection according to an exemplary embodiment. Figure 5 As shown, the network connection method is used in a terminal and includes the following steps.

[0100] In step S51, in response to detecting that a data transmission volume in a network connection established between a first device and a second device is less than a data transmission volume threshold within a first time.

[0101] In the embodiment of the present disclosure, the first device may detect that the data transmission volume in the network connection established between the first device and the second device is less than the data transmission volume threshold within the first time.

[0102] In the embodiment of the present disclosure, it can be detected by the second device that the data transmission volume in the network connection established between the first device and the second device is less than the data transmission volume threshold within the first time.

[0103] In one example, the first device detects that the amount of data transmission in the network connection established between the first device and the second device is less than a data transmission threshold within a first time. This may be that the first device detects that the amount of data transmission in the network connection established between the first device and the second device is less than the data transmission threshold within a first time, for example, 10 minutes, or there is no data transmission.

[0104] In step S52, a second message is sent to the second device or a second message sent by the second device is received through an out-of-band data OOB manner.

[0105] The second message includes a second type identifier.

[0106] The second type identifier is used to identify that the second message is used to temporarily disconnect the connected network, and the second message carries the first identifier.

[0107] In the embodiment of the present disclosure, the first device or the second device can determine that the second message is used to temporarily disconnect the connected network based on the second type identifier in the second message. The first device or the second device can determine the network connection that needs to be disconnected based on the first identifier in the second message. For example, when device 1 establishes a network connection with device 2 and device 1 establishes a network connection with device 3, wherein there is identifier 1 between device 1 and device 2, and there is identifier 2 between device 1 and device 3, device 1 can determine that it needs to temporarily disconnect the connected network with device 2 based on identifier 1 in the first message.

[0108] In an embodiment of the present disclosure, when a first device detects that a data transmission volume in a network connection established between the first device and the second device is less than a data transmission volume threshold within a first time, the first device may send second information to the second device to temporarily disconnect the network connection between the first device and the second device.

[0109] In an embodiment of the present disclosure, when the second device detects that the data transmission volume in the network connection established between the first device and the second device is less than the data transmission volume threshold within a first time, the first device can receive second information sent by the second device and temporarily disconnect the network connection between the first device and the second device based on the second information.

[0110] In an embodiment of the present disclosure, when it is detected that the data transmission volume between the first device and the second device is less than the data transmission volume threshold within the first time, the network device connected between the first device and the second device is temporarily disconnected through the second information, thereby reducing the power consumption consumed in establishing the network connection between the devices.

[0111] In the embodiment of the present disclosure, when the first device detects an instruction from the user to completely disconnect the established network connection, the network connection between the devices may be deleted, thereby completely disconnecting the network connection between the devices.

[0112] Figure 6 is a flow chart showing a complete network connection method according to an exemplary embodiment. Figure 6 As shown, the network connection method is used in a terminal and includes the following steps.

[0113] In step S61, in response to the first device and the second device stopping the network connection.

[0114] In the embodiment of the present disclosure, the first device may detect an instruction from a user to completely disconnect the established network connection. The first device is a GO terminal in the P2P direct connection group.

[0115] In the embodiment of the present disclosure, stopping the network connection between the first device and the second device may be that the first device and the second device temporarily stop the network connection based on the second message, or it may be when the first device detects that the user needs to stop the network connection between the first device and the second device.

[0116] In step S62, a third message is sent to the second device through an out-of-band data OOB manner, and the first identifier and the network configuration are deleted.

[0117] The third message includes a third type identifier.

[0118] The third type identifier is used to identify a third message, the third message is used to disconnect the connected network, and the third message carries the first identifier.

[0119] In the implementation of the present disclosure, when the first device detects that the user needs to completely disconnect the established network connection, a third message can be sent to the second device. The third message includes a third type identifier, and the third type identifier is used to determine that the third message is used to disconnect the connected network and delete the first identifier and the network configuration. The first identifier is carried in the third message.

[0120] In an embodiment of the present disclosure, when the network connection between the first device and the second device stops, third information is sent to the second device, so that the second device can delete the stored first identifier and the network configuration connected to the first device based on the third information, thereby completely disconnecting the network connection between the first device and the second device and preventing the first identifier from occupying device storage space as a network configuration.

[0121] In the embodiment of the present disclosure, the first device may send a fourth message in an out-of-band data OOB manner, thereby determining a second device that can establish a network connection with the first device.

[0122] Figure 7 is a flow chart showing a method for establishing a network connection according to an exemplary embodiment. Figure 7 As shown, the network connection method is used in a terminal and includes the following steps.

[0123] In step S71, in response to the first device establishing a network connection with the second device.

[0124] In the implementation of the present disclosure, after it is determined that a network connection is established between the first device and the second device, the first device saves the first identifier and the network configuration corresponding to the first device.

[0125] In step S72, a fourth message is sent to the second device via an out-of-band data OOB manner.

[0126] The fourth message may enable the second device to save the network configuration based on the first identifier.

When device 2 receives the C message sent by device 1, it stores the corresponding WLAN direct network configuration and disconnects from device 1.

[0152] In the embodiment of the present disclosure, when device 1 detects a data transmission request, it sends a D message to device 2, and restores the network settings in device 1 according to the network configuration. The D message contains an identifier that uniquely corresponds to the network. Device 2 receives the D message sent by device 1, searches for the network configuration corresponding to the identifier based on the identifier in the D message, and restores the network configuration of device 2, thereby realizing rapid reconstruction of the network connection between device 1 and device 2.
