Description

File sharing method, mobile device and computer storage medium

Technical Field

The embodiment of the application relates to the technical field of mobile equipment, in particular to a file sharing method, mobile equipment and a computer storage medium.

Background

The mobile device can communicate with other mobile devices through Wi-Fi, Bluetooth and the like, when the mobile device communicates with other mobile devices through Wi-Fi, the mobile device can serve as an Access Point (AP) and work in an AP mode to provide a signal source of a Wi-Fi network for other mobile devices, at the moment, the mobile device provides a Wi-Fi hotspot and can communicate with other mobile devices accessing the Wi-Fi hotspot, and a Wi-Fi module of the mobile device accessing the Wi-Fi hotspot works in a Station (STA) mode or a client (client) mode. Alternatively, the two mobile devices may be connected through a Peer-to-Peer (P2P) network, in which case the Wi-Fi modules of the two mobile devices operate in STA mode.

Generally, the STA mode and the AP mode of the Wi-Fi module are mutually exclusive, and if a mobile device needs to work in the STA mode and the AP mode simultaneously, it needs specific hardware and drive support, for example, the mobile device needs a Wireless Local Area Network (WLAN) chip with multiple independent hardware Access Control (MAC) layers, or, on the basis of drive support, physical channels are time-division multiplexed through hardware support. However, many current data transmission services require two mobile devices to establish a point-to-point connection shared file, such as a "space delivery" function of an IOS system and a shared file of an android system. For mobile equipment which cannot support simultaneous working in an STA mode and an AP mode, the services cannot be used when a Wi-Fi hotspot is started, a Wi-Fi hotspot network needs to be manually disconnected by a user, so that the connection between the mobile equipment and the equipment using the Wi-Fi hotspot network is interrupted, the Wi-Fi hotspot of the mobile equipment is manually started by the user after the service is used, and the experience of the user is poor when the service is used.

Disclosure of Invention

The embodiment of the application provides a file sharing method, mobile equipment and a computer storage medium, which can establish Wi-Fi connection with other mobile equipment under the condition of not disconnecting a Wi-Fi hotspot, so that a user does not need to close the Wi-Fi hotspot, and the use experience of the user is improved.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

a first aspect provides a file sharing method, including: the wireless fidelity Wi-Fi module of the first mobile device is turned on and provides a Wi-Fi hotspot for a third mobile device, the method comprising: the method comprises the steps that a first mobile device detects that a user starts a first operation of a sharing function; responding to the first operation, the first mobile equipment starts a short-distance wireless communication module; the first mobile equipment searches for the second mobile equipment by using the short-distance wireless communication module; the first mobile equipment detects a second operation that the user determines that the second mobile equipment is a target object using the sharing function; the method comprises the steps that the first mobile equipment sends Wi-Fi connection information to the second mobile equipment by using a short-distance wireless communication module, wherein the Wi-Fi connection information at least comprises the Wi-Fi hotspot opened by the first mobile equipment and the identity authentication information of the Wi-Fi hotspot connected with the first mobile equipment; the method comprises the steps that a first mobile device receives a Wi-Fi connection request of a second mobile device and identity authentication information sent by the second mobile device through a Wi-Fi module, wherein the Wi-Fi connection request of the second mobile device is used for requesting to access a Wi-Fi hotspot of the first mobile device in a station STA mode under the condition that the Wi-Fi hotspot of the second mobile device is not started, and the Wi-Fi connection request of the second mobile device is used for requesting to bridge the Wi-Fi hotspot of the first mobile device in an AP mode under the condition that the Wi-Fi hotspot of the second mobile device is started; the first mobile equipment verifies the identity authentication information sent by the second mobile equipment; after the first mobile device successfully verifies, establishing Wi-Fi connection with the second mobile device; the first mobile device shares the file with the second mobile device using a sharing function through a Wi-Fi connection.

The sharing function is a function that two mobile devices transmit Wi-Fi connection information through a short-range wireless communication module to establish Wi-Fi connection and then mutually transmit files by using the Wi-Fi connection, the sharing function can be a service provided by the mobile devices, and the shared files can be photos, documents, business cards, characters and the like. The sharing function requires the use of a Wi-Fi module and a short range wireless communication module (e.g., a near field communication NFC module, a bluetooth module, etc.) other than the Wi-Fi module, and thus, after detecting the first operation to enable the sharing function, the Wi-Fi module and the short range wireless communication module need to be turned on. In this embodiment, before the first operation is detected, the Wi-Fi module of the first mobile device is turned on, and the Wi-Fi hotspot is turned on, that is, the Wi-Fi module of the first mobile device operates in the AP mode. After a target object with a sharing function (namely, a target mobile device sharing a file) is confirmed to be a second mobile device, the short-range wireless communication module is used for informing the second mobile device that the first mobile device opens the Wi-Fi hotspot and identity authentication information of the Wi-Fi hotspot connected with the first mobile device, and further the second mobile device can access the hotspot opened by the first mobile device by using the identity authentication information, wherein under the condition that the Wi-Fi hotspot is not opened by the second mobile device, the Wi-Fi hotspot of the first mobile device is accessed by the second mobile device in a site STA mode, and under the condition that the Wi-Fi hotspot is also opened by the second mobile device, the Wi-Fi hotspot of the first mobile device is bridged by the second mobile device in an AP mode.

In one possible implementation, the third mobile device is in a second subnet established by the first mobile device, and after the first mobile device detects the second operation, the method further includes: the first mobile device allocates a network segment of a first subnet to a second mobile device, wherein the first subnet and the second subnet are isolated from each other. The first mobile device may configure whether the first subnet and the second subnet are isolated from each other. The established Wi-Fi connection and sharing function data transmission networks are isolated from each other by establishing the second subnet which is independent from the first subnet existing in the opened Wi-Fi hotspot, and the data transmission of the second mobile equipment and the third mobile equipment is isolated from each other, so that the data security is improved.

In one possible implementation, after the successful verification, the first mobile device establishes a Wi-Fi connection with the second mobile device, including: after the first mobile equipment is successfully verified, using a Dynamic Host Configuration Protocol (DHCP) service to allocate an Internet Protocol (IP) address belonging to a network segment of a first subnet to the second mobile equipment; and the first mobile equipment and the second mobile equipment establish Wi-Fi connection according to the allocated IP addresses, so that the second mobile equipment is in the first subnet.

In one possible implementation manner, after the first mobile device detects that the user enables the first operation of the sharing function, the method further includes: the method comprises the steps that a first mobile device detects whether a Wi-Fi hotspot is started or not; the first mobile equipment sets a first parameter according to the detection result, wherein the first parameter is used for indicating whether the first mobile equipment opens the Wi-Fi hotspot.

In one possible implementation manner, after the first mobile device and the second mobile device share the file, the first mobile device disconnects the Wi-Fi connection with the second mobile device.

In one possible implementation, a first mobile device searches for a second mobile device using a short-range wireless communication module, including: a first mobile device searches for other mobile devices enabling a short-range wireless communication module using a short-range wireless communication module; the first mobile device displays a search result list; the first mobile device detects a second operation used by the user to determine that the second mobile device is a target object using the sharing function, and the second operation comprises the following steps: the first mobile device detects a second operation of the user to select a second mobile device as a target object in the search result list.

In one possible implementation manner, the first operation is further configured to indicate a target file to be shared using a sharing function, and the sharing function is used by the first mobile device to share the file with the second mobile device through a Wi-Fi connection, including: the first mobile device sends the target file to the second mobile device through Wi-Fi connection by using a sharing function. For example, the first operation includes that the user clicks and selects a target file to be shared, and then selects to use a "sharing" function, that is, the first operation designates the target file to be shared and opens the "sharing function", and since the first mobile device has already opened the Wi-Fi module, after the first mobile device detects the first operation, the short-range wireless communication module is opened. After the short-range wireless communication module is started, the first mobile device searches a list of nearby devices by using the short-range wireless communication module and displays the list on a touch display screen of the first mobile device, the user executes a second operation, namely, selects a second mobile device from a search result list displayed on the touch display screen, and the first mobile device determines that the second mobile device selected by the user is a sharing object (file sending object) of the target file.

For example, the first operation is that the user lights up an icon of the "share function" in the pull-down function icon option, and since the first mobile device has already turned on the Wi-Fi module, the short-range wireless communication module is turned on after the first mobile device detects the first operation. After the user performs the first operation, a third operation may be performed to select one of the files in the first mobile device and select "share" to designate a target file to be shared. After detecting the third operation, the first mobile device searches a list of nearby devices using the short-range wireless communication module and displays the list on the display screen of the first mobile device, and then the user may perform the third operation to select the second mobile device in the displayed search result list to designate a sharing object (file transmission object) of the target file.

Detailed Description

Embodiments of the present embodiment will be described in detail below with reference to the accompanying drawings.

The file sharing method provided by the embodiment of the application can be applied to mobile equipment, such as mobile phones, tablet computers, personal computers and other mobile equipment.

As shown in fig. 1, an application scenario of the file sharing method provided in the embodiment of the present application is described by taking a mobile phone as an example. In the application scenario shown in fig. 1, the mobile phone a101 operates in an AP (access point) mode, and provides a Wi-Fi (wireless fidelity) hotspot network for the computer 103, and the mobile phone a101 may convert a signal based on a mobile communication standard such as 3G, 4G, or 5G received by the mobile phone a101 into a Wi-Fi signal to send out by using the Wi-Fi hotspot network, and provide mobile data for the computer 103, so that the computer 103 may connect to the internet. Optionally, the mobile phone a101 may also access a wireless router, communicate with the internet via the wireless router, forward a signal received from the wireless router through a hot spot, and send data sent by a mobile device accessing the hot spot of the mobile phone a101 through the wireless router.

When the mobile phone a101 and the mobile phone B102 need to share data using the sharing function, for example, the mobile phone a101 shares a picture in the mobile phone a101 with the mobile phone B102, and the mobile phone a101 and the mobile phone B102 first need to open the "sharing" function. It should be understood that: the sharing function is used for one device to send document files, pictures, audio files, video files, installation files and the like to one or more other devices in a wireless communication mode. For example, the sharing function may be an air drop of the apple IOS system, a fast share of the google android system (fast share). Two examples of opening a "share" feature shared file in a handset are provided below:

(1) as shown in fig. 2, to open an example of the "share" function, the user performs the following operations to open the "share" function of the mobile phone: and clicking an icon corresponding to the sharing function displayed in a pull-down control panel of the mobile phone. After the mobile phone opens the sharing function, it starts its own short-range wireless communication module (such as a bluetooth module, an NFC module, an infrared module, and other wireless communication modules, which will be described below with reference to the bluetooth module as an example) and Wi-Fi module. It should be understood that turning on the Wi-Fi module is different from turning on the Wi-Fi connection function in the mobile phone, where the Wi-Fi connection function in the mobile phone is to access an Access Point (AP) in a STA (station) mode, and turning on the Wi-Fi module in this embodiment of the present application is to enable the Wi-Fi module.

After the mobile phone starts the sharing function, the mobile phone starts the Wi-Fi module and the Bluetooth module and starts the search function of the Bluetooth module to search for a device which starts the Bluetooth module in a nearby preset range (the radius distance of the preset range is limited by the performance of the Bluetooth module). If the user needs to share a file, such as a picture, the user can select the file to be shared, open an "option" function card of the file (as shown in fig. 3), select "share" the picture (as shown in fig. 4), further display the name of the device searched through the bluetooth module (as shown in fig. 5), and optionally, if only one device is searched, the user does not need to be displayed on an interface of a mobile phone to select the device, and the searched device is automatically selected by default.

Alternatively, in this example, the bluetooth module may not search immediately after being turned on, but search after the user performs the operations shown in fig. 3 and 4 with respect to the file to be transmitted.

(2) Optionally, for a mobile phone that needs to send data to an opposite end, a manner of opening a "sharing" function may also be as shown in fig. 3 and 4: the user selects a file to be shared, opens an "option" function card of the file (as shown in fig. 3), selects "share" the photo (as shown in fig. 4), and can also trigger the function of opening the share through the above operation performed by the user. After the sharing function is turned on in the manner shown in fig. 3 and 4, the mobile phone turns on the Wi-Fi module and the bluetooth module, and starts the search function of the bluetooth module to search for a device in a nearby preset range (the radius distance of the preset range is limited by the performance of the bluetooth module) to turn on the bluetooth module, and further displays the name of the device searched by the bluetooth module (as shown in fig. 5).

The above description is merely two exemplary descriptions, and the embodiment of the present application does not limit the specific operation manner of enabling the sharing function. In addition, the sharing function may specifically be an application installed in the mobile device, and may also be an extended service provided by an operating system of the mobile device, which is also not specifically limited in this embodiment of the present application.

In the scenario shown in fig. 1, if taking an example that the mobile phone a101 shares one picture in the mobile phone a101 with the mobile phone B102, after the mobile phone a101 starts the sharing function in the manner of the above example (2) and the mobile phone B102 starts the sharing function in the manner of the above example (1), both the mobile phone a101 and the mobile phone B102 start their own Wi-Fi module and bluetooth module. After the mobile phone a101 or the mobile phone B102 starts the Wi-Fi module, it may detect whether the Wi-Fi module itself has started the Wi-Fi hotspot, and in order to indicate the detection result, a parameter (a first parameter) may be set to indicate whether the Wi-Fi hotspot itself has started, for example, if the Wi-Fi hotspot itself has been detected to have started, the first parameter is set to 1 to indicate that the Wi-Fi hotspot itself has started, and if the Wi-Fi hotspot has not been detected to have not started, the first parameter is set to 0 to indicate that the Wi-Fi hotspot itself has not started.

After the bluetooth module is turned on by the mobile phone a101, the search function can be immediately activated to search for surrounding devices which turn on the bluetooth module, including the mobile phone B102. At this time, the user wants to send a picture to the mobile phone B102, the operations shown in fig. 3 to fig. 5 may be executed for the picture (see the above description for the specific operation steps), after the searched device for opening the bluetooth module is displayed as shown in fig. 5, the user may click and select "mobile phone B102" in the interface shown in fig. 5, further, the mobile phone B102 may receive a request for sharing a file sent by the bluetooth module sent by the mobile phone a101, where the request is used to request to send a file to the mobile phone B102 with a "sharing" function, for example, as shown in fig. 6, the prompt content of the request displayed on the interface of the mobile phone B102 may be a request for asking the user whether to accept the request that the mobile phone a101 sends "picture 1", and after the user selects "accept" on the mobile phone B102, the mobile phone a101 and the mobile phone B102 start to interact-Fi connection information through the bluetooth module.

The Wi-Fi connection information is data needed by the two ends to establish Wi-Fi connection. For example, the Wi-Fi connection information sent by the cell phone a101 to the cell phone B102 may include information that the cell phone a101 has opened a Wi-Fi hotspot, and identity authentication information required to access the cell phone a 101. Optionally, the mobile phone B102 may also notify the mobile phone a101 of the current working mode of its Wi-Fi module through the bluetooth module, for example, the mobile phone B102 sends the first parameter to the mobile phone a101 through the bluetooth module, so as to notify the mobile phone a101 of whether it is working in a Wi-Fi hotspot mode. For the application scenario shown in fig. 1, the mobile phone a101 has already started the Wi-Fi hotspot and operates in the AP mode, and the mobile phone a101 notifies the mobile phone B102 that the Wi-Fi hotspot has already been started by itself by sending the first parameter, and similarly, the mobile phone B102 also sends the first parameter value of itself to the mobile phone a 101. Because the mobile phone a101 has already opened the Wi-Fi hotspot and the mobile phone B102 has not opened the Wi-Fi hotspot, the mobile phone a101 still sets itself to work in the AP mode and remains unchanged, and the mobile phone B102 sets itself to work in the STA mode.

The mobile phone a101 needs to verify the authentication information for the mobile device accessing the Wi-Fi hotspot, and therefore, the Wi-Fi connection information sent by the mobile phone a101 to the mobile phone B102 further includes the authentication information, for example, the authentication information may be an authentication token, that is, the authentication token may be included in the bluetooth information of the mobile phone a101 interacting with the mobile phone B102 through the bluetooth module. Optionally, the Wi-Fi connection information may be transmitted once or multiple times, for example, the mobile phone a101 may transmit the first parameter to the mobile phone B102 first, and after the mobile phone B102 feeds back and confirms that the first parameter is received, the mobile phone a101 sends a token to the mobile phone B102. After the mobile phone B102 receives the token sent by the mobile phone a101 through the bluetooth module, the mobile phone B102 may access the Wi-Fi hotspot of the mobile phone a101 according to the token.

In order to isolate the subnet where the Wi-Fi connection between the mobile phone a101 and the mobile phone B102 is located from the subnet where the Wi-Fi connection between the mobile phone a101 and the computer 103 is located, an independent subnet is newly established for the mobile phone B102, and correspondingly, the Wi-Fi connection information interacted through the bluetooth module further includes a network segment of the isolated subnet divided by the mobile phone a101 for the mobile phone B102, and optionally, the Wi-Fi connection information may be transmitted once or many times. For example, handset a101 creates an independent subnet, and sends the network segment information (e.g., subnet mask) of the created subnet to handset B102. By establishing the isolation sub-network, the user group containing sensitive data can be isolated from the rest part of the network, so that the possibility of revealing confidential information is reduced, if the mobile phone B102 and the computer 103 are in the same sub-network, the data of the computer 103 can be checked by the mobile phone B102, and under the condition that the mobile phone B102 and the computer 103 are in different sub-networks which are isolated from each other, the data of the mobile phone B102 and the computer 103 are invisible from each other, so that the security of the data is improved.

After the mobile phone A101 and the mobile phone B102 interact Wi-Fi connection information through the Bluetooth module, the Wi-Fi connection is established based on the Wi-Fi connection information. In an application scenario shown in fig. 1, the mobile phone a101 and the mobile phone B102 determine a connection manner for establishing a Wi-Fi connection according to whether an opposite terminal and the mobile phone B102 start a Wi-Fi hotspot, the mobile phone a101 operates in an AP mode, the mobile phone B102 operates in an STA mode (or referred to as a Client mode), the mobile phone B102 accesses the Wi-Fi hotspot of the mobile phone a101 according to token, and after the mobile phone B102 accesses the Wi-Fi hotspot of the mobile phone a101, the mobile phone a101 allocates an IP address of a newly-built isolated subnet to the mobile phone B102, where a specific allocation manner may be an automatic allocation manner using a DHCP protocol. After the above-mentioned process, the handset a101 and the handset B102 have established the Wi-Fi connection, and the handset a101 and the handset B102 transmit data through the established Wi-Fi connection.

After the Wi-Fi connection is established between the mobile phone a101 and the mobile phone B102, the Wi-Fi connection may be used to share files with each other, where the files may be sent from the mobile phone a101 to the mobile phone B102, or from the mobile phone B102 to the mobile phone a 101. After the file is sent, the Wi-Fi connection can be disconnected, and when the file needs to be shared again, the file sharing method provided by the embodiment of the application is executed again.

In the application scenario shown in fig. 7, the mobile phone a101 operates in the AP mode to provide a Wi-Fi hotspot network for the computer 103, and the mobile phone B102 provides a Wi-Fi hotspot network for the computer 104. If the mobile phone a101 and the mobile phone B102 need to share data, the sharing function "share data" may be started with reference to a data sharing method in an application scenario as shown in fig. 1, and the first parameter is transmitted through the bluetooth module to know that the Wi-Fi hotspot is started at the opposite end, and since the mobile phone a101 and the mobile phone B102 both work in the AP mode, the mobile phone a101 and the mobile phone B102 may establish Wi-Fi connection to a bridge network. When the bridge network is established, an independent subnet is established by a party needing to use the sharing function to send data, and the newly established subnet is accessed by a party receiving the data. For example, if a photo needs to be shared with the mobile phone B102 by using the mobile phone a101, the mobile phone a101 creates an independent subnet, and sends the network segment information (e.g., subnet mask) of the subnet to the mobile phone B102.

The bridge connection established between the mobile phone a101 and the mobile phone B102 can be isolated (independent) from the existing subnet, taking the example that the mobile phone B102 accesses the bridge network of the mobile phone a101, the Wi-Fi connection between the mobile phone a101 and the computer 103 is in the subnet a, the mobile phone a101 creates an independent subnet B for the mobile phone B102, the network segment of the subnet B is sent to the mobile phone B102, and the mobile phone B102 bridges into the subnet B in an AP mode. Since the mobile phone B102 is accessed to the isolated subnet established by the mobile phone a101, the Wi-Fi connection between the mobile phone a101 and the computer 103 is not disconnected, and the Wi-Fi connection between the mobile phone B102 and the computer 104 is not disconnected.

The application scenario shown in fig. 7 is a scenario in which both the cell phone a101 and the cell phone B102 start a Wi-Fi hotspot, the cell phone a101 and the cell phone B102 may establish a Wi-Fi connection in a bridge connection manner, and both the two bridge-connected parties operate in an AP mode. The bridge connection established between the mobile phone a101 and the mobile phone B102 is in a subnet isolated (independent) from the existing subnet of the mobile phone where the bridge connection is established, taking the example that the mobile phone B102 accesses the bridge network of the mobile phone a101, if the Wi-Fi connection between the mobile phone a101 and the computer 103 is in the subnet a, the mobile phone a101 creates an independent subnet B and sends the network segment of the subnet B to the mobile phone B102, the mobile phone B102 bridges into the subnet B of the mobile phone a101 that also works in the AP mode, and after the mobile phone a101 and the mobile phone B102 establish the Wi-Fi connection in the bridge mode, the Wi-Fi connection between the mobile phone a101 and the computer 103 is not disconnected due to the connection established in the independent subnet.

In the application scenario shown in fig. 8, neither the cell phone a101 nor the cell phone B102 opens the Wi-Fi hotspot, and there is no device accessing the Wi-Fi hotspot. After the mobile phone a101 and the mobile phone B102 interact with Wi-Fi connection information through the bluetooth module, the mobile phone a101 and the mobile phone B102 may establish a connection using a connection mode of a Peer-to-Peer network (P2P), that is, a Wi-Fi Direct connection (Wi-Fi Direct), and both the mobile phone a101 and the mobile phone B102 operate in an STA mode.

A file sharing method provided in an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

As shown in fig. 10, a file sharing method provided in an embodiment of the present application includes:

for a first mobile device side:

step 1, the first mobile device detects that a user opens the sharing function.

And 2, after the sharing function is opened, the first mobile equipment starts the Wi-Fi module and the Bluetooth module.

And 3, after the first mobile device starts the Wi-Fi module, detecting whether the first mobile device starts the Wi-Fi hotspot.

And 4, setting a first parameter for indicating whether the Wi-Fi hotspot is started or not according to the detection result. The first parameter is used for indicating whether the transmitting end opens the Wi-Fi hotspot. For example, the first parameter may be an identification bit flag in the transmitted data, and if the flag is 0, it indicates that the Wi-Fi hotspot is not turned on, and if the flag is 1, it indicates that the Wi-Fi hotspot is turned on.

And 5, searching nearby Bluetooth equipment after the Bluetooth module is started.

And 6, after the second mobile equipment is searched, performing Bluetooth handshake with the second mobile equipment to transfer the first parameters and other Wi-Fi connection information.

And 7, selecting a Wi-Fi connection mode according to the first parameter.

Step 8, if the Wi-Fi hotspot is not opened by the first mobile device and the second mobile device, establishing a P2P connection, wherein the first mobile device and the second mobile device both work in an STA mode; if the first mobile device and the second mobile device both open the Wi-Fi connection, establishing a bridge connection, and enabling the first mobile device and the second mobile device to work in an AP mode; if the first mobile device already opens the Wi-Fi hotspot and the second mobile device does not open the Wi-Fi hotspot, the second mobile device accesses the Wi-Fi hotspot of the first mobile device; if the Wi-Fi hotspot is opened by the second mobile device and not opened by the first mobile device, the first mobile device accesses the Wi-Fi hotspot of the second mobile device. When the bridge connection is established or the Wi-Fi hotspot is accessed, the connection can be established through the independent isolated sub-network.

And 9, establishing the Wi-Fi connection in a selected mode. After the connection is established, the two mobile devices may share data over the established Wi-Fi connection.

Correspondingly, the steps executed by the second mobile device side are similar to the steps executed by the first mobile device side, and are not described herein again.

The sharing function uses a Wi-Fi connection to transmit data with other mobile devices, for example, the sharing function may be a shared file (such as a photo, a document, a business card, a character, an audio file, a video file, etc.) service provided by the mobile device, and the file is transmitted between the two mobile devices through the Wi-Fi connection. In order to enable two mobile devices to share data, an embodiment of the application provides a method for establishing a connection, after a sharing function is started, whether a Wi-Fi hotspot is started or not is detected, a short-range wireless communication module (such as near field communication NFC, a bluetooth module and the like) outside a Wi-Fi module is used for negotiating with an opposite terminal to confirm enabling states of the Wi-Fi hotspots of the two mobile devices, if the Wi-Fi hotspot is started at one end, the two mobile devices can establish a network through the Wi-Fi hotspot provided at the end where the Wi-Fi hotspot is started, and if the Wi-Fi hotspot is started at both ends, the two mobile devices can establish a bridge network to avoid an operation of closing the Wi-Fi hotspot, so that user experience is improved.

The Wi-Fi connection information at least includes a first parameter, for example, the first parameter may be an identification bit flag in the transmission data, and if the flag is 0, it is determined that the Wi-Fi hotspot is not turned on, and if the flag is 1, it is determined that the Wi-Fi hotspot is turned on.

Optionally, the Wi-Fi connection information may further include an authentication key of the Wi-Fi connection. For example, the authentication key may be a token, which is provided to the other end by the end that has opened the Wi-Fi hotspot, and after the token is provided to the other end by the end that has opened the Wi-Fi hotspot using the short-range wireless communication module, the other end may access to the end that has opened the Wi-Fi hotspot using the token. Alternatively, the authentication key may be a pre-shared key PSK, or the like. The embodiments of the present application do not specifically limit this. In addition to the examples mentioned above, the Wi-Fi connection information can also include a media access control layer MAC address, a Wi-Fi connection key, and so on.

In order to make other devices (e.g., computers) accessing one end of the open Wi-Fi hotspot (e.g., a first mobile device) invisible to another mobile device (e.g., a second mobile device), a separate subnet may be used to separate the different devices accessing the first mobile device. In one possible implementation, after the first mobile device establishes a Wi-Fi connection with the second mobile device using the Wi-Fi hotspot, the first mobile device and the second mobile device are in a first subnet, wherein the first subnet is at least isolated from a second subnet, and the second subnet is a subnet in which the Wi-Fi connection established by the first mobile device with the third mobile device using the Wi-Fi hotspot is located. The two subnetworks isolated from each other may be implemented by establishing isolated subnetworks and/or by dividing virtual local area networks, VLANs. The isolation subnet is established by setting network segments of a plurality of subnets by using one Wi-Fi module. The VLAN is divided, actual subnets are not established, and the mutual isolation and shielding of devices of different subnets are realized in a mode of establishing virtual subnets. VLAN is a logical subnet built on a physical network to enhance security of the lan, and user groups containing sensitive data can be isolated from the rest of the network to reduce the possibility of revealing confidential information.

In one possible implementation, in a case where the first mobile device turns on a Wi-Fi hotspot and the second mobile device does not turn on the Wi-Fi hotspot, after the first mobile device establishes a Wi-Fi connection with the second mobile device using the Wi-Fi hotspot, the method further includes: the first mobile equipment divides the network segment of the first subnet; and the first mobile equipment allocates the IP address belonging to the first subnet to the second mobile equipment according to the division result. That is, under the condition that the first mobile device starts the Wi-Fi hotspot and the second mobile device does not start the Wi-Fi hotspot, the first mobile device may establish a newly added subnet for the second mobile device after the second mobile device accesses the Wi-Fi hotspot of the first mobile device, divide a network segment of the subnet, and allocate an IP address belonging to the network segment of the newly added subnet to the second mobile device. For example, the network segment of the isolated subnet allocated and set by the first mobile device to the second mobile device is 192.168.2.X, or the network segment of the VLAN network allocated and set by the first mobile device to the second mobile device is 10.0.0.X, and the network segment allocated by the first mobile device to the second mobile device is isolated from the first mobile device and the third mobile device (for example, the computer in fig. 1). Optionally, the first mobile device allocates an IP address to the second mobile device using a dynamic host configuration protocol, DHCP, service.

In one possible implementation, in a case that the second mobile device opens the Wi-Fi hotspot, and the first mobile device does not open the Wi-Fi hotspot, after the first mobile device establishes a Wi-Fi connection with the second mobile device using the Wi-Fi hotspot, the method further includes: the first mobile device controls other components in the first mobile device (e.g., other services that may be an operating system or other applications installed in the mobile device) other than the shared functionality to disable the Wi-Fi connection. By limiting the use of Wi-Fi connection for other components in the second mobile device, the file in the first mobile device is made invisible to other components in the second mobile device, improving the security of data in the first mobile device.

In one possible implementation, in a case where the first mobile device and the second mobile device both have opened the Wi-Fi hotspot, after the first mobile device or the second mobile device closes the Wi-Fi hotspot, the first mobile device establishes a Wi-Fi connection with the second mobile device using the Wi-Fi hotspot that still exists. For example, a user of a first mobile device may close a Wi-Fi hotspot, and interact with a second mobile device after closing the Wi-Fi hotspot to mutually confirm whether an opposite terminal enables the Wi-Fi hotspot, and since only the second mobile device opens the Wi-Fi hotspot at this time, the first mobile device may access the Wi-Fi hotspot of the second mobile device to establish a Wi-Fi connection.

Optionally, the short-range wireless communication module may be a near field communication NFC module or a bluetooth module. Alternatively, the short-range wireless communication module may be a Radio Frequency IDentification (RFID) module, an infrared module, or the like.

According to the file sharing method, the drive layer does not need to be modified, the working state of WIFI is controlled and monitored in a unified mode on the service layer, the two ends negotiate the Wi-Fi connection mode through other communication technologies except Wi-Fi, connection is established, the Wi-Fi hotspot does not need to be closed by a user in the opening state of the Wi-Fi hotspot, the Wi-Fi hotspot does not flow out, complex network control and protocol switching on the drive layer are not needed, system complexity and operation convenience are reduced, and the problems of user interaction inconsistency and inconvenience of multiple switching are solved.
