Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

In the related art, file sharing is generally implemented by using an FTP (File Transfer Protocol) method, but there are fewer devices supporting the FTP, and the efficiency of File sharing based on the FTP is relatively low, which results in a relatively low sharing speed, and when a File to be shared is relatively large, the experience is very poor. Secondly, the synchronization of the FTP is poor, when a user needs to modify a file across devices, the file to be modified needs to be stored in the current device, and the modified file needs to be shared with another device after the modification is completed, so that the operation process is complicated, and the user experience is poor.

The disclosure provides a file sharing method applied to a first device. In the method, a first wireless connection (for example, a bluetooth connection) is established between a first device and a second device, the first device and the second device are determined to be in the same local area network through the first wireless connection, and then a file of the second device is shared through the local area network, so that the first device and the second device establish file sharing.

For example, when the first wireless connection is a bluetooth connection, most devices have a bluetooth function and a wireless connection function, so the file sharing method has a wider application range, and is higher in sharing speed and efficiency and better in user experience due to file sharing based on a local area network.

In one exemplary embodiment, a file sharing method is provided and applied to a first device. Referring to fig. 1 and 3, the method includes:

s110, establishing a first wireless connection with second equipment;

s120, receiving file sharing request information sent by second equipment based on first wireless connection under the condition that the first equipment and the second equipment are in the same local area network;

and S130, based on the file sharing request information, hanging the second device on the first device so as to share the file of the second device through the local area network.

In step S110, the first wireless connection may include a bluetooth connection, and the bluetooth connection may be a classic bluetooth connection or a Bluetooth Low Energy (BLE) connection.

For example, the first wireless connection is a bluetooth low energy connection, in this step, after the first device starts the bluetooth low energy function, the first device sends a corresponding broadcast, the second device receives the broadcast and determines that the bluetooth low energy connection is established with the first device, the first device receives feedback information that the second device has determined that the connection is established, and the first device can establish the bluetooth low energy connection with the second device, so as to implement bluetooth communication between the first device and the second device.

The low power consumption Bluetooth is a personal area network technology designed and sold by the Bluetooth technical alliance; bluetooth low energy is intended to significantly reduce power consumption and cost while maintaining equivalent communication range compared to classical bluetooth.

It should be noted that the types of the first device and the second device may be the same or different. For example, the first device and the second device may both be cell phones. For another example, the first device is a computer and the second device is a mobile phone.

In step S120, it may be determined whether the first device and the second device are in the same local area network based on the first wireless connection, and if the first device and the second device are not in the same local area network, the first device and the second device may also be in the same local area network through the first wireless connection.

After determining that the first device and the second device are in the same local area network, the second device may send file sharing request information to the first device based on the first wireless connection, where the file sharing request information may include, for example, an internet protocol address of the second device, a sharing password of the second device, an identifier of the second device, and the like. The first device may receive the file sharing request message based on the first wireless connection.

In step S130, the first device may mount the second device, that is, mount the second device on the first device, based on the received file sharing request information and a mount function, so that the first device establishes file sharing with the second device. After the second device is mounted on the first device, the file of the second device can be shared through the same local area network connected with the first device and the second device.

It should be noted that, in this method, the file sharing request information is generated by the second device and then sent to the first device, and after the first device mounts the second device, the file of the second device may be generally operated at the first device, for example, the file of the second device is viewed and edited.

In the case of example 1, the following examples,

the first wireless connection is a low-power Bluetooth connection, the first device is a computer, and the second device is a mobile phone.

The user can start the low-power-consumption Bluetooth function of the computer firstly, so that the computer adds GATT (Generic Attribute Profile) service, and after the computer successfully adds the GATT service, the broadcast for realizing the low-power-consumption Bluetooth connection is sent. The broadcast may include a UUID (universal Unique Identifier).

The mobile phone can scan periodically or irregularly, when the mobile phone scans the broadcast comprising the UUID, the mobile phone can pop up a prompt window for prompting a user whether to allow the user to establish the low-power Bluetooth connection with the computer, and when the user determines that the user allows the establishment of the low-power Bluetooth connection, the mobile phone establishes the low-power Bluetooth connection with the computer and can stop scanning so as to reduce power consumption.

In addition, when the user determines that the Bluetooth low energy connection is allowed to be established, the mobile phone can generate the determined connection information and send the determined connection information to the computer. After the computer receives the determined connection information, the computer can stop sending the broadcast so as to reduce power consumption.

After the low-power Bluetooth connection is established between the mobile phone and the computer, data can be mutually transmitted through the characteristic value.

When the mobile phone and the computer are in the same local area network, the mobile phone can generate a shared password, and then the internet protocol address (IP address), the equipment identifier and the shared password of the mobile phone are sent to the computer through the low-power Bluetooth communication.

After the computer receives the internet protocol address (IP address) and the device identifier and the shared password, the mobile phone can be mounted based on the mounting function, that is, the computer and the mobile phone establish file sharing, so as to share the file of the mobile phone through the local area network. The user can operate the files on the mobile phone on the computer, so that the use experience of the user is improved.

The mobile phone and the computer can be provided with Bluetooth interaction modules to realize the low-power Bluetooth connection and transmit information through the low-power Bluetooth connection.

Because most of devices have the Bluetooth function with low power consumption and the wireless connection function, the file sharing method is wider in application range, and based on the file sharing of the local area network, the file sharing speed is higher, the efficiency is higher, and the use experience of a user is better.

It should be noted that, when the computer sends the broadcast for implementing the first wireless connection, since the mobile phone does not know the specific moment when the computer sends the broadcast, the mobile phone may scan periodically or aperiodically in the on-screen state, and compared with the classic bluetooth, the bluetooth low energy may reduce the power consumption of the mobile phone.

In the case of example 2, the following example was carried out,

the first device is a first computer, and the second device is a second computer. After the first computer and the second computer establish file sharing, a user can process files of the second computer at the first computer, using experience is improved, and the method can also realize cooperative work.

In one exemplary embodiment, a file sharing method is provided and applied to a first device. In the method, before determining that the first device and the second device are in the same local area network, the method may further include:

s210, sending verification information to the second equipment based on the first wireless connection;

and S220, receiving verification success information sent by the second equipment.

In step S210, the authentication information may include user information of the first device, that is, information of a user who logs in the first device. For example, the authentication information may be an Identification (ID) of a user logged into the first device.

In step S220, authentication success information is generated by the second device in response to the authentication information matching the target information of the second device. Wherein the target information may include user information of the second device. For example, the target information may be an identity of a user logged into the second device.

In the method, a first device sends authentication information to a second device based on a first wireless connection. The second device receives the authentication information sent by the first device based on the first wireless connection. The second device compares the received verification information with the target information of the second device, if the verification information is the same as the target information, the verification information is matched with the target information, verification success information can be generated, and then the verification success information is sent to the first device based on the first wireless connection, so that the first device and the second device are ensured to be used by the same user, and the file sharing safety is improved.

In the case of example 1, the following examples,

the first device is a computer, and the second device is a mobile phone. The first wireless connection is a bluetooth connection. The verification information is the identity of the user logging in the computer and is marked as ID1. The identity of the user with the target information of the login mobile phone is marked as ID2.

The mobile phone and the computer can be provided with user information verification modules for completing the verification of the user identity.

After the bluetooth connection is established between the mobile phone and the computer, the computer can start an Auth Server (authentication service) of the computer, and the service can acquire the identity ID1 of the user logging in the computer. Meanwhile, the mobile phone may start an Auth Server (authentication service) of the mobile phone, and the service may obtain an identity ID2 of a user who logs in the mobile phone.

The computer can then send ID1 to the handset via the bluetooth connection. After receiving the ID1 sent by the computer through the Bluetooth, the mobile phone compares the ID1 with the ID2 of the mobile phone and if the ID1 is the same as the ID2, the mobile phone and the computer are the same user, and the mobile phone can generate verification success information and then sends the verification success information to the computer through the Bluetooth connection. The computer can receive the verification success information through Bluetooth connection, so that the security of file sharing between the mobile phone and the computer is improved.

In the method, whether the user identifier of the first device is matched with the user identifier of the second device is determined through the user information checking module, and the subsequent step of establishing the file sharing can be carried out only under the condition that the user identifier of the first device is matched with the user identifier of the second device, so that the file sharing safety between the first device and the second device can be improved.

It should be noted that, regarding the verification of the user information, the second device may also send the target information to the first device based on the first wireless connection, and after receiving the target information, the first device may compare the target information with the verification information of the first device, and if the target information and the verification information are matched, may perform the subsequent step of "determining that the first device and the second device are in the same local area network".

In addition, if the first device determines that the received target information is matched with the verification information of the first device, verification success information can also be generated, and the verification success information can be sent to the second device based on the first wireless connection, so that the second device determines that the user information verification of the first device and the user information verification of the second device are successful.

In one exemplary embodiment, a file sharing method is provided and applied to a first device. In the method, after the second device is loaded on the first device, the method may further include:

s310, determining that the local area network is abnormal;

s320, the second device is unloaded from the first device.

In step S310, the first device may include a lan status detection module, which may check the link status of the lan between the first device and the second device through the ICMP packet.

The ICMP packet is a network communication packet. ICMP is an abbreviation for Internet Control Message Protocol (Internet Control Message Protocol). The ICMP control packet is a message used to detect network problems such as network failure, host availability, and available route.

For example, a first device may start a Network Status Server (Network Status service), which may establish a socket connection with a second device that establishes a file share (a long connection, in theory, once the long connection is established between the first device and the second device, the first device and the second device will not be actively disconnected), and may send an ICMP packet at a certain time, determine the connection and disconnection of the Network by whether the ICMP packet has a response, and calculate the delay by the time length of the ICMP packet response.

And when the first equipment cannot receive the response of the ICMP data packet or the response time length of the first equipment is greater than or equal to the set delay time length, determining that the local area networks where the first equipment and the second equipment are located are abnormal.

In step S320, the first device may directly uninstall the mounted second device, that is, the second device is uninstalled from the first device, so that the file sharing between the first device and the second device is disconnected, and the user cannot operate the file of the second device on the first device.

In addition, in the method, after the second device is loaded on the first device, the method may further include:

s410, receiving first control information for unloading the second equipment;

and S420, based on the first control information, the second device is off-loaded from the first device.

In step S410, the first control information may be control information that the second device transmits to the first device, or may be control information that the user directly inputs to the first device.

When the first control information is control information sent by the second device to the first device, the second device may include a lan status detection module, which may check a link status of a lan where the first device and the second device are located through an ICMP packet.

For example, the second device may start a Network Status Server and may periodically send ICMP packets. When the second device cannot receive the response of the ICMP packet, or the response duration is longer than or equal to the set delay duration, it is determined that the local area network where the first device and the second device are located is abnormal, and the second device may send, to the first device, first control information based on the first wireless connection, where the first control information is used to enable the first device to uninstall the second device, that is, the first control information is used to cancel the second device from being hung on the first device, so that the first device disconnects file sharing with the second device.

When the first control information is control information directly input to the first device by the user, the user can input the first control information to the first device through a key or a touch screen.

In step S420, after the first device receives the first control information, the mounted second device may be uninstalled based on the first control information, so as to disconnect file sharing between the first device and the second device.

It is noted that after un-loading the second device from the first device, the method further comprises;

The second control information may be information that characterizes that the first device successfully uninstalls the second device, that is, the second control information may be information that characterizes that the first device successfully disconnects file sharing with the second device.

After the first device disconnects the file sharing with the second device, that is, after the first device unloads the second device, the first device may generate an uninstallation success information and then transmit the uninstallation success information to the second device through the first wireless connection. And after receiving the uninstalling success information, the second device can close the file sharing function of the second device.

For example, the second device may turn off the Samba service to turn off the file sharing function. Wherein, samba is free software for realizing SMB protocol, and is composed of a server and a client program. SMB (Server Messages Block, information services Block) is a communication protocol for sharing files and printers on a lan, and provides a sharing service of resources such as files and printers between different computers in the lan.

It should be noted that, in the method, when the second device cannot receive the response of the ICMP packet, or the response duration is longer than or equal to the set delay duration, the second device may directly close its file sharing function.

According to the method, whether the file sharing between the first device and the second device is disconnected or not can be determined based on the requirements of the user or whether the file sharing between the first device and the second device is abnormal or not, and the use experience of the user can be further improved.

In one exemplary embodiment, a file sharing method is provided that employs a first device. In the method, determining that the first device and the second device are in the same local area network may include at least one of:

mode 1, determining that a first device and a second device are connected to the same wireless network;

mode 2, determining a network hotspot where a first device is connected to a second device;

mode 3, a network hotspot where the second device is connected to the first device is determined.

The mode 1 may include at least one of the following cases.

In the case of the situation 1 that is,

if it is determined that the first device and the second device are currently connected to the same valid wireless network based on the first wireless connection, the same valid network may be determined to be a local area network, and it may be determined that the first device and the second device are in the same local area network.

The first device may send, to the second device, a network identifier of a valid wireless network to which the first device is connected based on the first wireless connection, where the network identifier may include, for example, a BSSID (the BSSID refers to a MAC address of the wireless network). For convenience of description, BSSID of a valid wireless network to which the first device is connected is denoted as BSSID1.

The second device may receive BSSID1 based on the first wireless connection. The BSSID of the valid wireless network to which the second device is connected is denoted as BSSID2. And the second device compares the BSSID1 with the BSSID2, and if the BSSID1 is identical with the BSSID2, the first device and the second device are currently connected with the same effective wireless network, so that the first device and the second device are determined to be in the same local area network.

In the case of 2, the first and second cases,

if the first device and the second device are determined to be connected to different effective wireless networks currently based on the first wireless connection, receiving network information of the effective wireless network currently connected with the second device, and enabling the first device to be connected to the effective wireless network currently connected with the second device based on the network information so as to determine that the first device and the second device are in the same local area network.

The second device compares the received BSSID1 sent by the first device with the BSSID2 of the second device, and if the two BSSIDs are different, it is determined that the first device and the second device are currently connected to different valid wireless networks.

The second device may send, to the first device, network information of a valid wireless network to which the second device is currently connected based on the first wireless connection, where the network information may include a BSSID (which may be BSSID 2) of the valid wireless network and a connection password (which may be passcode 2) of the valid wireless network.

After receiving the BSSID2 and the password2 based on the first wireless connection, the first device may connect to the valid wireless network to which the second device is currently connected based on the BSSID2 and the password2, so as to determine that the first device and the second device are in the same local area network.

In the case of the situation 3,

if the first equipment is determined to be currently connected to the effective wireless network based on the first wireless connection, and the second equipment cannot be currently connected to the effective wireless network, sending network information of the effective wireless network currently connected with the first equipment to the second equipment, so that the second equipment is connected to the effective wireless network currently connected with the first equipment, and the first equipment and the second equipment are determined to be in the same local area network.

When the second device cannot be connected to the valid wireless network, the first device may send, to the second device, network information of the valid wireless network to which the first device is currently connected based on the first wireless connection, where the network information may include BSSID1 and a connection password of the valid wireless network, and the connection password may be written as password1.

After receiving the BSSID1 and password1 based on the first wireless connection, the second device may connect to the valid wireless network to which the first device is currently connected, thereby determining that the first device and the second device are in the same local area network.

It should be noted that, in this manner 1, if it is determined that the first device and the second device are currently connected to different effective wireless networks based on the first wireless connection, network information of the effective wireless network to which the first device is currently connected may also be sent to the second device, so that the second device is connected to the effective wireless network to which the first device is currently connected, so as to determine that the first device and the second device are in the same local area network.

The first device may send BSSID1 and password1 of the valid wireless network to which the first device is currently connected to the second device based on the first wireless connection.

After receiving the BSSID1 and password1 based on the first wireless connection, the first device may connect to the active wireless network to which the second device is currently connected, so as to determine that the first device and the second device are in the same local area network.

In the method, the mode 2 may include: and receiving hotspot information of the network hotspot of the second equipment so as to enable the first equipment to be connected to the network hotspot.

For example, if it is determined that neither the first device nor the second device is connected to the valid wireless network, the second device may open its own data traffic and open a network hotspot, and then send network information of the network hotspot to the first device based on the first wireless connection, where the network information may include BSSID (which may be referred to as BSSID 3) and connection password (which may be referred to as password 3) of the network hotspot.

After receiving the BSSID3 and the password3 based on the first wireless connection, the first device may connect to a network hotspot opened by the second device based on the BSSID3 and the password3, so that the first device and the second device are in the same local area network.

In the method, the mode 3 may include: and opening a network hotspot of the first device, and sending hotspot information of the network hotspot to the second device so as to enable the second device to be connected to the network hotspot.

It is checked whether a connection to a valid wireless network (i.e., an available wireless network) has been made.

The network topology detection module of the computer can check whether the WLAN function of the computer is started or not, and if the WLAN function of the computer is in a starting state. It is checked whether a connection to a valid wireless network (i.e., an available wireless network) has been made.

After the user information is successfully verified, if the mobile phone and the computer are determined to be connected to the effective wireless network, whether the BSSID1 of the effective wireless network connected with the computer is the same as the BSSID2 of the effective wireless network connected with the mobile phone can be judged.

And if the BSSID1 and the BSSID2 are the same, determining that the mobile phone and the computer are connected to the same wireless network, and accordingly determining that the mobile phone and the computer are in the same local area network.

If BSSID1 and BSSID2 are different, the computer can send BSSID2 and password2 of the effective wireless network connected with the computer to the mobile phone based on low-power-consumption Bluetooth connection, and the mobile phone can be connected to the effective wireless network connected with the computer after receiving the BSSID2 and the password2, so that the mobile phone and the computer are connected to the same wireless network, and the mobile phone and the computer are confirmed to be in the same local area network.

And if the mobile phone is not connected to the effective wireless network and the computer is connected to the effective wireless network, enabling the mobile phone to be connected to the effective wireless network connected to the computer based on BSSID2 and password2 of the effective wireless network connected to the computer.

If the mobile phone and the computer are not connected to the effective wireless network, the mobile phone can be used for data traffic and network hotspots, BSSID3 and password3 of the network hotspots are sent to the computer based on low-power-consumption Bluetooth connection, the computer is connected to the network hotspots, and therefore the mobile phone and the computer are located in the same local area network.

In the method, the local area network where the mobile phone and the computer are located can be selected according to the following rules: the effective wireless network connected with the mobile phone is superior to the effective wireless network connected with the computer, the effective wireless network connected with the computer is superior to the 5G network of the mobile phone, the 5G network of the mobile phone is superior to the 2.4G network of the mobile phone, the 2.4G network of the mobile phone is superior to the 5G network of the computer, and the 5G network of the computer is superior to the 2.4G network of the computer.

For example, if the mobile phone is connected with an effective wireless network, the computer is also connected with the effective wireless network, so that the mobile phone and the computer are in the same local area network; if the mobile phone is not connected to the effective wireless network and the computer can be connected to the effective wireless network, the mobile phone is connected to the effective wireless network connected with the computer, so that the mobile phone and the computer are in the same local area network; if the mobile phone and the computer are not connected to the effective wireless network and the mobile phone can open 5G data traffic, the computer is connected to the network hotspot where the mobile phone is opened, so that the mobile phone and the computer are in the same local area network. By analogy, the mobile phone and the computer are always in the optimal local area network, so that the file sharing efficiency is improved.

In the method, the authentication information may include user information of the first device, that is, information of a user who logs in the first device. For example, the authentication information may be an Identification (ID) of a user logged into the first device.

The target information may include user information of the second device. For example, the target information may be an identity of a user logged into the second device.

It should be noted that, regarding the verification of the user information, the second device may also send the target information to the first device based on the first wireless connection, and after receiving the target information, the first device may compare the target information with the verification information of the first device, and if the target information is matched with the verification information of the first device, may perform the subsequent step of "determining that the first device and the second device are in the same local area network".

In one exemplary embodiment, a file sharing service is provided for use with a second device. In the method, after the second device is loaded on the first device, the method may further include:

s710, determining that the local area network is abnormal, or receiving third control information for canceling the second device from being hung on the first device;

In step S710, the second device may include a lan status detection module, which may check whether the lans where the first device and the second device are located are abnormal through the ICMP packet.

The third control information may be control information transmitted from the first device to the second device, or may be control information directly input to the first device by the user.

In step S720, after determining that the local area network is abnormal or receiving third control information for canceling the second device from being hung on the first device, the second device may generate the first control information.

The second device may then send first control information to the first device based on the first wireless connection, the first control information to un-suspend the second device from the first device.

After the first device receives the first control information, the mounted second device can be unloaded based on the first control information, so that the second device is not mounted on the first device, and the file sharing between the first device and the second device is disconnected.

And after receiving the unloading success information, the second device can close the file sharing function of the second device.

In the method, whether the second device is not hung on the first device or not can be determined based on the requirement of the user or whether the file sharing between the first device and the second device is abnormal, and the use experience of the user can be further improved.

In addition, it should be noted that, in the method, the first device and the second device are determined to be in the same local area network, in a similar manner to the above-mentioned file sharing method applied to the first device, it may also include at least one of the following:

For a specific situation, reference may be made to the file sharing method applied to the first device, which is not described herein again.

The method can enable the mobile phone and the computer to be always in the optimal local area network, so that the file sharing efficiency is improved.

In one exemplary embodiment, a file sharing method is provided and applied between a first device and a second device.

Referring to fig. 1 to 3, in the method, the first device may be a computer, the second device may be a mobile phone, and the first wireless connection may be a bluetooth low energy connection.

In addition, when the user determines that the Bluetooth low energy connection is allowed to be established, the mobile phone can generate the determined connection information and send the determined connection information to the computer. After the computer receives the determined connection information, the computer can stop sending the broadcast so as to reduce the power consumption.

After the low-power-consumption Bluetooth connection is established between the mobile phone and the computer, data can be mutually transmitted through the characteristic value.

The computer can then send ID1 to the handset via the bluetooth connection. After receiving the ID1 sent by the computer through the Bluetooth, the mobile phone compares the ID1 with the ID2 of the mobile phone and if the ID1 is the same as the ID2, the mobile phone and the computer are the same user, and the mobile phone can generate verification success information and then sends the verification success information to the computer through the Bluetooth connection. The computer can receive the successful verification information through Bluetooth connection, so that the security of file sharing between the mobile phone and the computer is improved.

The local area network where the mobile phone and the computer are located can be selected according to the following rules: the effective wireless network connected with the mobile phone is superior to the effective wireless network connected with the computer, the effective wireless network connected with the computer is superior to the 5G network of the mobile phone, the 5G network of the mobile phone is superior to the 2.4G network of the mobile phone, the 2.4G network of the mobile phone is superior to the 5G network of the computer, and the 5G network of the computer is superior to the 2.4G network of the computer.

For example, the network topology detection module of the handset may check whether the WLAN function (wireless connection function) of the handset is on, if the WLAN function of the handset is on. It is checked whether a connection to a valid wireless network (i.e., an available wireless network) has been made.

If BSSID1 and BSSID2 are different, the computer can send BSSID2 and password2 of an effective wireless network connected with the computer to the mobile phone based on low-power-consumption Bluetooth connection, and the mobile phone can be connected to the effective wireless network connected with the computer after receiving the BSSID2 and the password2, so that the mobile phone and the computer are connected to the same wireless network, and the situation that the mobile phone and the computer are in the same local area network is determined.

And if the mobile phone is not connected to the effective wireless network and the computer is connected to the effective wireless network, enabling the mobile phone to be connected to the effective wireless network to which the computer is connected based on BSSID2 and password2 of the effective wireless network to which the computer is connected.

By analogy, the mobile phone and the computer are always in the optimal local area network, and the subsequent file sharing efficiency is improved.

Under the condition that the mobile phone and the computer are determined to be in the same local area network, the file sharing module of the mobile phone may generate file sharing request information, and the file sharing request information may include, for example, an internet protocol address of the mobile phone, a sharing password of the mobile phone, an identifier of the mobile phone, and the like.

After the file sharing request information is generated, smbpasswd can be started to create the sharing password in the Samba service, so that the mobile phone can realize file sharing through the sharing password. After the Samba service shared password is successfully set, nmbd and smbd can be started, wherein nmbd is responsible for verifying parameters such as passwords during mounting, and smbd is responsible for all subsequent shared work.

Then, the mobile phone can send the sharing request information to the computer based on the low-power Bluetooth connection. After the computer receives the internet protocol address (IP address) and the device identifier and the shared password, the mobile phone can be mounted based on the mounting function, that is, the computer and the mobile phone establish file sharing, so as to share the file of the mobile phone through the local area network. The user can operate the files on the mobile phone on the computer, so that the use experience of the user is improved.

After the mobile phone and the computer establish file sharing, the local area network state detection modules of the mobile phone and the computer can detect the link condition of the local area network.

The computer can start a Network Status Server (Network state service), the service can establish socket connection with the computer which establishes file sharing, and can send an ICMP data packet at regular time, the on-off of the Network is determined by whether the ICMP data packet has a response, and the time delay is calculated by the response time length of the ICMP data packet.

And when the computer cannot receive the response of the ICMP data packet or the response time length of the computer is longer than or equal to the set time delay, determining that the local area network where the mobile phone and the computer are located is abnormal.

If the computer detects the local area network abnormality, the mounted mobile phone can be forcibly unloaded.

Similarly, the mobile phone can also detect whether the local area Network is abnormal through the Network Status Server. If the mobile phone detects that the local area network is abnormal, the Samba service can be closed so as to close the file sharing function and forcibly stop mounting.

In addition, the user can also directly input third control information to the mobile phone so as to control the mobile phone to stop being mounted. Or, the user can also directly input the first control information to the computer to control the computer to unload the mounted mobile phone.

It should be noted that, after the computer successfully uninstalls the mobile phone, the computer may generate an uninstallation success message, and then send the uninstallation success message to the mobile phone through the low power consumption bluetooth connection. After the mobile phone receives the information of successful uninstallation, if the file sharing function is closed, the file sharing function of the mobile phone can be closed, so that the energy consumption is reduced.
