In the description of the embodiments of the present application, "/" indicates an alternative meaning, for example, a/B may indicate a or B; "and/or" herein is merely an associative relationship describing an associated obstacle, and means that there may be three relationships, e.g., a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more, and "at least one", "one or more" means one, two or more, unless otherwise specified.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather mean "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

Wi-Fi (Wireless-Fidelity) refers to Wi-Fi operating in the 5GHz (5150MHz-5825MHz) radio frequency band and using the Institute of Electrical and Electronics Engineers (IEEE) standard. With the fact that 2.4G frequency bands used by Wi-Fi networks are more crowded and cannot meet development requirements, 5G frequency bands are opened in various countries successively, and compared with 2.4G Wi-Fi, 5G Wi-Fi has a higher wireless transmission speed. For example, the 2.4G channel and 5G channel information involved in different Wi-Fi standards specified by IEEE may be as shown in table 1:

TABLE 1

At present, most of 5G Wi-Fi channels belong to military and civil mixed use, the development condition is complex, for example, the open 5G Wi-Fi channels in different regions are different; 5G Wi-Fi channel regulations in different countries may also change over time; also, for example, channels in the 5G band are divided into indoor channels and outdoor channels, wherein some countries stipulate that the indoor channels cannot be used by devices operating outdoors, and so on. Different regulations cause the availability of 5G Wi-Fi channels to be different at different times in different countries and under different scenarios.

When new and old equipment are cloned by changing a machine, if the data quantity to be backed up is large, the 5G frequency band is used for data transmission, and the data transmission efficiency can be greatly improved. Considering that the 5G frequency band is complex to use, when data cloning is performed in the 5G frequency band, new and old devices need to negotiate and determine a consistent 5G channel for interaction. In a possible implementation manner, the new device and the old device may select a certain channel from an intersection of 5G channels supported by both parties for interaction, so as to implement data cloning on a 5G frequency band. The process may be referred to in particular by the flow chart shown in fig. 1.

Illustratively, as shown in fig. 1, a schematic flow chart of data transmission between old and new devices is shown. The process comprises the following steps:

s101(a), a new device inquires a supported 5G channel list;

s101(b), the old equipment inquires a supported 5G channel list;

s102, the old equipment sends a 5G channel list supported by the old equipment to the new equipment;

s103, the new device compares whether the 5G channel lists respectively supported by the new device and the old device have intersection or not;

there are two cases of alignment in this step: case 1, the two channels have an intersection; in case 2, there is no intersection between the two channels. Wherein:

if the comparison result is case 1, step S104 is executed, that is, the new device and the old device perform data transmission on the 5G channel supported by both sides;

if the comparison result is case 2, step S105 is executed, that is, the new device and the old device perform data transmission on the 2.4G channel.

The data transmission process shown in fig. 1 may be implemented by an application (App) installed on the new device and the old device (e.g., a clone application), and the process needs to be implemented on the basis that the clone application can obtain a list (or set) of 5G channels supported by the old device. However, in practical applications, some systems do not provide a standard interface of a chip 5G channel, and at this time, if the clone application installed on the old device is a third party App, the clone application cannot query a 5G channel list supported by the old device, and the new device and the old device cannot confirm the 5G channel commonly supported by both devices by comparing the channel lists.

In view of the above problems, embodiments of the present application provide a data transmission method, where in a case where a list of 5G channels supported by an old device cannot be obtained, a new device attempts to establish Wi-Fi connection between a 5G channel supported by the new device and an opposite terminal according to a preset rule, so that a possibility that the new device and the old device perform clone data transmission on the 5G channel is improved, and user experience is improved.

For example, the first electronic device 100 may be installed with a clone application (e.g., a clone on switch App) that may be used to interact with the user, such as receiving a clone on switch request input by the user, presenting the user with the old device type of data to be transferred, prompting the user for progress of data transfer, and so on. In this embodiment, the cloning application may call a 5G channel list query interface of the first electronic device to query the 5G channels supported by the first electronic device 100. In addition, the first electronic device 100 may also have a bluetooth (bluetooth) communication capability by which the first electronic device 100 may establish a bluetooth connection with the second electronic device 200; the first electronic device 100 supports Wi-Fi communication capabilities, which may include Wi-Fi communication capabilities over a 2.4G band, or Wi-Fi communication capabilities over a 5G band.

In some embodiments, the second electronic device 200 may be a sending device of clone data for sending backup data to the first electronic device 100, and the second electronic device 200 may also be described as a sending device (or sender) below. For example, the second electronic device 200 may be installed with a clone application, which may be a third party application of the second electronic device 200 when the type of the second electronic device 200 is not identical to the type of the first electronic device 100. In this embodiment, the second electronic device 200 may not have a general interface for querying the 5G channel, that is, the clone application cannot actively query the 5G channel supported by the second electronic device 200. In addition, the second electronic device 200 may support a bluetooth communication capability, and may be capable of establishing a bluetooth connection with the first electronic device 100 through the bluetooth communication capability; the second electronic device may also support Wi-Fi communication capabilities, which may be Wi-Fi communication capabilities over a 2.4G frequency band or Wi-Fi communication capabilities over a 5G frequency band.

In some embodiments, the second electronic device 200 may be, for example, an old device used by the user in the past, and the first electronic device 100 may be, for example, a new device newly acquired by the user to replace the second electronic device 200.

The data transmission method provided by the embodiment of the application is suitable for an application scene of performing clone-change between new and old equipment, namely when a user needs to migrate data on the old equipment to the new equipment, the possibility that the two parties transmit the data on a 5G channel can be improved by the data transmission method provided by the embodiment of the application, and therefore the data transmission efficiency is improved. For example, as shown in fig. 5A to 5C, some Graphical User Interfaces (GUIs) that may be involved in the data transmission process provided in the embodiment of the present application are schematically illustrated. For convenience of understanding, the GUI shown in fig. 5A to 5C is used as an interface in the first electronic device 100, and the first electronic device 100 is described as a new mobile phone.

In some embodiments, the new handset is installed with a change machine clone App, which may be a factory-owned application for the new handset. After the user opens the switch machine cloning App on the main interface of the new mobile phone, as shown in fig. 5A, the new mobile phone may display the main interface after the switch machine cloning App is opened.

For example, a status bar may be displayed above the switch clone App host interface, and the status bar may include: one or more signal strength indicators for mobile communication signals (or cellular signals), one or more signal strength indicators for Wi-Fi signals, a battery level indicator for a handset, a time indicator, etc. Under the status bar, the switch machine cloning APP main interface may further include a relevant description of the switch machine cloning function, such as "migrating data of contacts, pictures, schedules, etc. to a new device at a fire speed" shown in fig. 5A; a device type selection area is also included below the functional description, in which the device types include a new device (this is a new device (reception data) "as shown in fig. 5A) and an old device (this is an old device (transmission data)" as shown in fig. 5A). In some embodiments, if the user currently operates the new mobile phone, the user may click and select an icon corresponding to "this is new equipment"; if the user currently operates the old mobile phone, the icon corresponding to the old equipment can be clicked and selected. For example, if the currently operated mobile phone is a new device, the user may input an operation 501 for an icon corresponding to "this is a new device", where the operation 501 may be, for example, a new device type selection operation such as clicking, long-pressing, and the like; when the new handset receives a new device selection operation 501 input by the user, an old device type selection page as shown in fig. 5B may be displayed in response to the operation 501.

Illustratively, as shown in FIG. 5B, the old device type selection interface may include a plurality of old device types for the user to select, such as the same old device type as the new handset (e.g., the new handset is glory, then one of the old device types displayed by the interface may also be glory),

Old device type (e.g. old handset if it is other than glory)

The type can be corresponded when using the mobile phone)

Old device type (such as used by old handset if iPhone, iPad, etc.)

The devices of the system may then correspond to that type).

In some embodiments, it is assumed that the old handset is a different type of other handset than the new handset

The device, the user may input an operation 502 for an icon corresponding to another android device, where the operation 502 may be, for example, an old device type selection operation such as clicking, long pressing, and the like; when the new handset receives an old device type selection operation 502 input by the user, an old device selection interface as shown in fig. 5C may be displayed in response to the operation.

For example, as shown in fig. 5C, the old device selection interface may include a description for guiding the user to perform a connection operation on the old handset, such as "open a ' clone changed machine ' on the old device ', select ' this is the old device ', scan the two-dimensional code below to establish a connection"; the two-dimensional code required for establishing connection between the new mobile phone and the old mobile phone can be displayed below the description content, wherein the two-dimensional code can be used for indicating a Service Set Identifier (SSID) and a password of a Wi-Fi hotspot of the new mobile phone, so that the new mobile phone and the old mobile phone can negotiate a Wi-Fi channel in the following process. According to the description information, the user can scan the two-dimensional code on the new mobile phone through the switch clone APP installed on the old mobile phone, wherein a schematic diagram of a two-dimensional code scanning interface of the old mobile phone can be as shown in fig. 6.

In response to the operation of scanning the two-dimensional code of the new mobile phone by the old mobile phone, the new mobile phone can establish a bluetooth connection with the old mobile phone, and the bluetooth connection establishment process can comprise the following steps: when the new mobile phone is not matched with the old mobile phone and the old mobile phone scans the two-dimensional code displayed by the new mobile phone, triggering the new mobile phone to open the Bluetooth function; then, the new mobile phone can send Bluetooth broadcast to the periphery; when the old mobile phone is in an inquiry Bluetooth scanning (inquiry scan) state, the old mobile phone can scan the Bluetooth broadcast sent by the new mobile phone; in response to the scanned Bluetooth broadcast, the old mobile phone can send a Bluetooth response to the new mobile phone, so that the new mobile phone acquires the old mobile phone as a pairable device option; the new handset may then send a page request to the old handset. The old mobile phone can monitor the paging request of the new mobile phone at a certain frequency modulation frequency within a fixed time window at fixed intervals, and after the paging request of the new mobile phone is monitored, the old mobile phone can send a slave paging response (slave page response) to the new mobile phone at the next time slot; after receiving the slave paging response of the old mobile phone, the new mobile phone can send a master paging response (master page response) to the old mobile phone in the next time slot; and then, the old mobile phone and the new mobile phone finish pairing authentication, and the Bluetooth connection for transmitting data can be established.

It should be noted that, in the bluetooth connection process, the new mobile phone and the old mobile phone may establish the bluetooth connection in an implicit manner, that is, when the bluetooth connection is triggered to be established, the new mobile phone and the old mobile phone may not prompt the user to turn on information such as bluetooth, but may automatically turn on the bluetooth function, and complete the bluetooth connection establishment process without the perception of the user.

In some embodiments, in order to avoid the problem that the bluetooth connection cannot be successfully established through the two-dimensional code, the old device selection interface may further include a prompt area for manually establishing the bluetooth connection between the new mobile phone and the old mobile phone. The prompt area may specifically include a description about manual bluetooth connection establishment, for example, "if the two-dimensional code cannot be connected when being scanned, please click the manual connection below the scanning interface of the old device, and connect the WLAN below", where local area network WLAN connection information and a password may be displayed below the description. In addition, for the case where the old handset does not have the "change machine clone" installed, the old device selection interface may also include an install link for the "change machine clone". For example, when the user inputs a selection operation for the "clone-changed" installation link (i.e., "please click here to install") in fig. 5C, the new mobile phone may send the installation information of the "clone-changed" application to the old mobile phone through bluetooth communication, so that the old mobile phone installs the "clone-changed" APP based on the installation information.

It should be noted that the GUI schematic diagrams shown in fig. 5A to 5C are only examples, and in practical applications, the interface may further include other more icons or description information, which is not limited in this embodiment of the application.

In a possible implementation manner, when the second short-range Wi-Fi module does not have a communication interface, the second short-range Wi-Fi module cannot successfully acquire the 5G channel query information sent by the second channel negotiation module, and then the second channel negotiation module cannot successfully acquire the 5G channel list fed back by the second short-range Wi-Fi module. In this case, the 5G channel list generated by the second channel negotiation module, and the 5G channels included in the 5G channel list are empty.

In some embodiments, the second channel negotiation module may send a list of 5G channels supported by the second electronic device to the second bluetooth module; the second bluetooth module may transmit the 5G channel list to the first bluetooth module through a bluetooth channel. In some embodiments, on the first electronic device side, after receiving the list of 5G channels supported by the second electronic device, the first bluetooth module may send it to the first channel negotiation module. The first channel negotiation module may determine, according to the 5G channel list supported by the first electronic device and the received 5G channel list supported by the second electronic device, whether an intersection exists between the 5G channel sets supported by the two parties, that is, whether a jointly supported 5G channel exists between the first electronic device and the second electronic device.

In an implementation manner, if there is an intersection between the 5G channels supported by the two parties, the first channel negotiation module may negotiate, through the first bluetooth module, with the second channel negotiation module via the bluetooth channel to establish a 5G Wi-Fi connection on a certain 5G channel in the intersection, and then perform a data transmission process on the 5G channel. In one implementation, the first clone characteristic module may further send 5G hotspot opening information to the first connection module; the first connection module can send the 5G hotspot opening information to the first short-distance Wi-Fi module after receiving the 5G hotspot opening information, and instructs the first short-distance Wi-Fi module to open the 5G hotspot on a 5G channel supported by both sides. And then, the first electronic device and the second electronic device establish 5G Wi-Fi connection through the first short-distance Wi-Fi module and the second short-distance Wi-Fi module respectively, and finally the first electronic device and the second electronic device can perform data transmission on the 5G channel for establishing connection through the first transmission module and the second transmission module respectively.

In another implementation manner, if there is no intersection between the 5G channels supported by the two parties (the method for data transmission provided in this embodiment of the present application is mainly used for this situation), the first channel negotiation module may generate 5G capability query information, where the 5G capability query information is used to query whether the second electronic device supports the 5G Wi-Fi communication capability. The first channel negotiation module sends the 5G capability inquiry information to the first Bluetooth module; after receiving the 5G capability query information, the first Bluetooth module can send the 5G capability query information to the second Bluetooth module through a Bluetooth channel.

And on the second electronic equipment side, the second Bluetooth module sends the 5G capability query information to the second channel negotiation module after receiving the 5G capability query information. After receiving the 5G capability query information, the second channel negotiation module may send the 5G capability query information to the second Wi-Fi short-range communication module through a general interface, where, for example, the general interface for 5G capability query may be: Wi-FiManager is5GHzBandSupported (). After receiving the 5G capability query information, the second short-range Wi-Fi module may feed back a result of whether the second electronic device supports the 5GWi-Fi communication capability to the second channel negotiation module. Thereafter, the second channel negotiation module may transmit the 5G capability inquiry result to the second bluetooth module. After receiving the 5G capability inquiry result, the second bluetooth module may send the result to the first bluetooth module via a bluetooth channel.

On the first electronic device side, after receiving the 5G capability query result, the first bluetooth module may send it to the first channel negotiation module.

In some embodiments, if the 5G capability query result indicates that the second electronic device supports the 5G Wi-Fi communication capability, the first channel negotiation module may randomly select one of the 5G channels supported by the first electronic device to attempt to connect to the second electronic device through 5G Wi-Fi connection. If the connection is successful, the subsequent first electronic equipment and the second electronic equipment can perform data transmission on the 5G channel; if the connection is not successful, the first electronic device may close the 5G hotspot, open the 2.4G hotspot, and establish Wi-Fi connection with the second electronic device on the 2.4G channel.

Or, optionally, if the connection is not successful, the first electronic device may randomly select another channel from the 5G channels supported by the first electronic device, and continuously perform an attempt to establish a 5G Wi-Fi connection with the second electronic device until obtaining the 5G channel on which both sides can successfully establish a connection. If after the attempt, all the 5G channels supported by the first electronic device cannot enable the two parties to successfully establish connection, the first electronic device may close the 5G hotspot, open the 2.4G hotspot, and establish Wi-Fi connection with the second electronic device on the 2.4G channel.

According to the data transmission method provided by the embodiment of the application, under the condition that the sending equipment cannot provide the 5G channel supported by the sending equipment, the receiving equipment selects the 5G channel supported by the receiving equipment to try to establish connection with the sending equipment, and when the connection is tried successfully, the receiving equipment and the sending equipment perform clone data transmission on the 5G channel.

Illustratively, as shown in fig. 8, a timing diagram of a method for data transmission according to an embodiment of the present application is provided. The method comprises the following steps:

s801, a first UX display module receives a first operation input by a user.

The first UX display module is a module in a clone application installed in the first electronic device. The first electronic device may be, for example, a receiving device (or called receiving end) for receiving data that needs to be backed up by a user when the clone is changed, and the first electronic device may be, for example, a new device of the user.

The first operation may be, for example, a receiver-side flow triggering operation input by the user through the cloned application installed by the first electronic device in the switch-machine cloning scenario, where the first operation may be, for example, a start operation of the cloned application, or may also be an old device type selection operation in the cloned application (which may correspond to operation 502 shown in fig. 5B).

First, at the receiving end, the first electronic device may perform the following steps:

s802, the first UX display module sends receiving end flow triggering information to the first clone character module.

The receiving end flow triggering information is used for indicating the first clone characteristic module to start a switch clone flow of the receiving end. For example, the switch machine cloning flow of the receiving end may include: the method comprises the steps of displaying a two-dimensional code comprising Wi-Fi hotspot connection information, establishing Bluetooth connection with second electronic equipment and the like.

And S803, responding to the receiving end process trigger information, and generating two-dimensional code information by the first clone characteristic module.

The two-dimensional code information comprises Wi-Fi connection information of the first electronic device, such as an SSID and a password of a Wi-Fi hotspot. Specifically, the Wi-Fi connection information may be connection information of a 5G Wi-Fi hotspot, and may include an SSID of the 5G Wi-Fi hotspot and a corresponding password.

S804, the first clone characteristic module sends two-dimensional code information to the first UX display module.

And S805, the first UX display module indicates a display screen to display the two-dimensional code.

In some embodiments, after receiving the two-dimension code information, the first UX display module may instruct the display screen to display a corresponding two-dimension code, where the two-dimension code is used to instruct Wi-Fi connection information (such as an SSID of a Wi-Fi hotspot and a corresponding password). As an example, an interface of the first electronic device displaying the two-dimensional code may be as shown in fig. 5C, for example.

Thereafter, at the transmitting end, the second electronic device may perform the following steps:

and S806, the second UX display module receives a second operation input by the user.

The second UX display module is a module in clone application installed in the second electronic device. The second electronic device may be a sending device (or called sending end) for sending data that needs to be backed up by a user when the clone is changed, and the second electronic device may be, for example, an old device of the user.

The second operation may be, for example, a sender flow triggering operation input by the user through a clone application installed by the second electronic device in a machine-changing clone scenario. Illustratively, the second operation may be a two-dimensional code scanning interface opening operation input by a user through a clone application installed by the second electronic device, and the two-dimensional code scanning interface may be as shown in fig. 6, for example.

And S807, the second UX display module sends sending end flow triggering information to the second clone characteristic module.

And S808, the second clone characteristic module responds to the trigger information of the flow of the sending end to indicate that the camera is started.

For example, the second clone characteristic module may indicate a camera (e.g., a rear camera) of the second electronic device to be turned on in response to the sending end process trigger information, so as to perform two-dimensional code scanning next.

And S809, the second clone characteristic module sends two-dimensional code scanning interface starting information to the second UX display module.

And S810, the second UX display module indicates a display screen to display a two-dimensional code scanning interface.

In some embodiments, after receiving the two-dimensional code scanning interface starting information, the second UX display module may instruct the display screen to display the two-dimensional code scanning interface based on the information. For example, the two-dimensional code scanning interface displayed by the second electronic device may be as shown in fig. 6.

S811, the second electronic device scans the two-dimensional code of the first electronic device and obtains Wi-Fi connection information indicated by the two-dimensional code.

The second electronic device can scan the two-dimensional code displayed by the first electronic device through the two-dimensional code scanning interface. Then, the second UX display module may acquire Wi-Fi hotspot connection information indicated by the two-dimensional code, where the Wi-Fi hotspot connection information may include an SSID of a Wi-Fi hotspot of the first electronic device 5G and a corresponding password.

And S812, the second UX display module sends Wi-Fi connection information to the second clone characteristic module.

S813, the second clone feature module sends Wi-Fi connection information to the second short-range Wi-Fi module.

And S814, the second short-distance Wi-Fi module tries to connect with the Wi-Fi indicated by the Wi-Fi connection information according to the Wi-Fi connection information.

In some embodiments, if the second electronic device supports 5G Wi-Fi communication capabilities, the second short-range Wi-Fi module, upon receiving the Wi-Fi connection information, may periodically traverse its own supported 5G channel, attempting to establish a Wi-Fi connection with the first short-range Wi-Fi module. For example, the second electronic device may send a Wi-Fi connection request message on a certain 5G channel supported by itself, where the Wi-Fi connection request message may include an SSID of a Wi-Fi hotspot of the first electronic device and a corresponding password; when the Wi-Fi connection is not successfully established on the 5G channel, the second electronic device can switch to other 5G channels supported by the second electronic device to resend the Wi-Fi connection request message. When the 5G Wi-Fi connection with the first electronic device is not successfully established after traversing all the 5G channels supported by the second electronic device, the second electronic device may perform the Wi-Fi connection request process again at a certain time interval.

It should be noted that, at the first electronic device side, the operation of sending the two-dimensional code information to the first UX display module by the first clone characteristic module may trigger the first clone characteristic module to send bluetooth activation information to the first bluetooth module. On the second electronic device side, the second clone specific module acquires Wi-Fi connection information and can trigger the second clone characteristic module to send Bluetooth starting information to the second Bluetooth module. Thereafter, the first electronic device and the second electronic device may perform a bluetooth connection establishment procedure.

S815, the first electronic device and the second electronic device perform a bluetooth connection establishment procedure.

For example, the bluetooth connection establishment process may refer to a schematic flowchart shown in fig. 9, and a specific process will be described below, which is not detailed here for the moment.

In some embodiments, after the first electronic device and the second electronic device establish a bluetooth connection, the first electronic device may perform the following steps:

s816, the first electronic device executes a 5G channel list comparison process.

For example, the 5G channel list comparison process can refer to the schematic flowchart shown in fig. 10, and a specific process will be described below and will not be described in detail here.

It should be noted that after the first electronic device compares the 5G channel lists supported by both parties, two cases may exist in the obtained comparison result: in case 1A, the 5G channel lists of both parties have an intersection; in case 1B, there is no intersection between the 5G channel lists of both parties.

Case 1A and case 1B are introduced with specific channel list examples. In case 1A, assume that the list of 5G channels supported by the first electronic device is: [ 3638404446132153157161165 ], the list of 5G channels supported by the second electronic device is: [ 36404448149463159161165 ], then the intersection of the 5G channels supported by the first electronic device and the second electronic device is: [36404448153161165]. In case 1B, assume that the list of 5G channels supported by the first electronic device is: [ 404448128132157165 ], the list of 5G channels supported by the second electronic device is: [ 364246149153155161 ], at this time, the intersection of the 5G channels supported by the first electronic device and the second electronic device is [ ], that is, the set of 5G channels supported by both devices is empty. Wherein, the element in the channel list is a channel number (channel number).

Optionally, when the 5G channel list fed back by the second electronic device is empty, the indication may also be expressed in other manners, for example, specific information (e.g., null) is carried in the channel response information sent by the second electronic device to the first electronic device to indicate that the channel list is empty, which is not limited in this embodiment of the application.

For case 1A, that is, when there is an intersection between the first electronic device and the supported 5G channel list of the second electronic device, the first electronic device may perform the following steps:

and S817, the first channel negotiation module sends 5G hotspot opening information to the first short-distance Wi-Fi module.

The 5G hotspot opening information is used for indicating the first short-distance Wi-Fi module to open the 5G hotspot.

For example, the specific process that the first channel negotiation module sends the 5G hotspot opening information to the first short-range Wi-Fi module may include: the first channel negotiation module first sends the 5G hotspot opening information to the first connection module, and then the first connection module sends the 5G hotline opening information to the first Wi-Fi module (fig. 8 does not show the first connection module).

And S818, the first short-distance Wi-Fi module screens a 5G channel and starts a 5G hotspot.

In some embodiments, after receiving the 5G hotspot opening information, the first short-range Wi-Fi module may perform 5G channel screening in an intersection of 5G channels supported by the first electronic device and the second electronic device, and open the 5G hotspot on the screened 5G channel. For example, when there are multiple 5G channels included in the intersection of the 5G channel lists of the first electronic device and the second electronic device, the first electronic device may select to open a 5G hotspot on the 5G channel where the signal strength is optimal.

For case 1B, that is, when there is no intersection between the first electronic device and the 5G channels supported by the second electronic device (for example, the 5G channel list fed back by the second electronic device is empty), the first electronic device may perform the following steps:

s819, the first electronic device queries whether the second electronic device supports the 5G capability.

For example, the second electronic device 5G capability query process may refer to the schematic flowchart shown in fig. 11, and a specific process will be described below, which is not detailed here for the moment.

Wherein the 5G capability query result of the second electronic device may include the following situations: case 2A, the second electronic device does not support 5G capability; case 2B, the second electronic device supports 5G capabilities.

For case 2A, that is, when the second electronic device does not support the 5G capability, the first electronic device may perform the following steps:

s820, the first electronic device starts a 2.4G hotspot.

For case 2B, that is, when the second electronic device supports the 5G capability, the first electronic device may perform the following steps:

s821, the first electronic device opens the 5G hot spot and tries to establish 5G Wi-Fi connection.

S822, the first electronic device and the second electronic device create a data transmission channel.

For example, the implementation process of step S820 in case 2A, step S821 in case 2B, and step S822 can refer to the schematic flowcharts shown in fig. 12 to fig. 14 below, and specific processes will be described below and will not be described in detail here.

It should be noted that, in case 2A, that is, when the second electronic device does not support the 5G capability, the data transmission channel created by the first electronic device and the second electronic device in step S822 is a 2.4G channel, where the 2.4G channel is a 2.4G channel supported by both the first electronic device and the second electronic device. The process of establishing the 2.4G channel by the first electronic device and the second electronic device may refer to an existing flow, which is not described herein again. In case 2B, that is, when the second electronic device supports the 5G capability, the data transmission channel of the first electronic device and the second electronic device may be a 5G channel in step S822, where the 5G channel is a certain 5G channel commonly supported by the first electronic device and the second electronic device.

In some embodiments, after the first electronic device and the second electronic device establish the data transmission channel, the second clone character module may support the second UX display module to display the transmission data selection interface. For example, the transmission data display interface may include a plurality of application icons and selection frames, such as a contact icon, an information icon, a call record icon, an album icon, a mail icon, a WeChat icon, and their corresponding selection frames, which are selectable by the user, as shown in fig. 16A. In addition, the quantity and the size of information included by each application program can be respectively displayed below each application program, and a full selection box and a cancel box, a transmission starting control and a transmission canceling control can be further displayed below the application program display area.

It should be noted that the types of the application icons and the amount and size of the information corresponding to each application included in the transmission data selection interface shown in fig. 16A are merely examples, and are not limited.

S823, the second electronic device receives a third operation input by the user.

The third operation is a transmission data selection operation input by the user, and the third operation may be, for example, a click operation of the user on a selection frame corresponding to the application program in the interface shown in fig. 16A. Taking the data in the contact, the information, the call record, the photo album and the mail which need to be transmitted by the user as an example, the third operation may be an operation of clicking a selection frame in front of the contact icon, the information icon, the call record icon, the photo album icon and the mail icon by the user.

In some embodiments, after the user selects to transmit data, the first electronic device and the second electronic device may perform the following steps:

s824, the first electronic device and the second electronic device perform data transmission.

For example, the implementation process of step S824 may refer to the schematic flowchart shown in fig. 15 below, and a specific process will be described below and will not be detailed here for the moment.

According to the data transmission method provided by the embodiment of the application, under the condition that the sending equipment cannot provide the 5G channel supported by the sending equipment, the receiving equipment selects the 5G channel supported by the receiving equipment to try to establish connection with the sending equipment, and when the connection is tried successfully, the receiving equipment and the sending equipment perform clone data transmission on the 5G channel, so that the efficiency of clone data transmission can be improved, and the use experience of a user is improved.

The bluetooth connection establishment procedure in step S815 will be described below with reference to the drawings. Illustratively, as shown in fig. 9, a schematic flow chart of a process for establishing a bluetooth connection between a first electronic device and a second electronic device. The process comprises the following steps:

s8151, the first clone character module sends Bluetooth starting information to the first Bluetooth module.

In some embodiments, the operation of the first clone property module sending the two-dimensional code to the first UX display module (corresponding to step S804 described above) may trigger the first clone property module to send bluetooth activation information to the first bluetooth module, where the bluetooth activation information is used to instruct the first bluetooth module to activate the bluetooth function. More specifically, the bluetooth activation information may be used to instruct the first bluetooth module to perform a bluetooth connection function of the master device.

S8152, responding to the Bluetooth starting information, the first Bluetooth module sends Bluetooth broadcast.

Accordingly, at the transmitting end, the second electronic device may perform the following steps:

and S8153, the second clone characteristic module sends Bluetooth starting information to the second Bluetooth module.

In some embodiments, the operation of the second clone property module obtaining Wi-Fi connection information (corresponding to step S812 above) may trigger the second clone property module to send bluetooth enable information to the second bluetooth module of the second electronic device, where the bluetooth enable information is used to instruct the bluetooth module to enable a bluetooth function. More specifically, the bluetooth activation information may be used to instruct the second bluetooth module to perform a bluetooth connection function of the slave device.

And S8154, responding to the Bluetooth starting information, and carrying out Bluetooth scanning by the second Bluetooth module.

S8155, the second Bluetooth module and the first Bluetooth module establish Bluetooth connection.

The specific process of establishing the bluetooth connection may refer to the above related description, and is not described herein again.

It should be noted that, in the embodiment of the present application, a process of establishing a bluetooth connection is described by taking a first electronic device as a master device and a second electronic device as a slave device. However, in other embodiments, in the bluetooth connection establishment process, the first electronic device may also serve as a slave device, and the second electronic device may also serve as a master device, which is not limited in this embodiment of the present application.

It should be further noted that the bluetooth connection established between the first electronic device and the second electronic device is mainly used for negotiation between the two parties to perform Wi-Fi channel negotiation, for example, the first electronic device may query, through the bluetooth channel, a 5G channel supported by the opposite end, whether the 5G capability is supported, and the like. In the embodiment of the present application, only the bluetooth connection is taken as an example, but in practical applications, the communication connection may also be another type of communication connection that enables the first electronic device and the second electronic device to interact with each other to negotiate the relevant information.

S8156, the first Bluetooth module sends Bluetooth connection establishment information to the first channel negotiation module, and the Bluetooth connection establishment information is used for indicating that Bluetooth connection establishment is completed.

After the first channel negotiation module receives the bluetooth connection information, the 5G channel comparison process may be performed in response to the bluetooth connection information (i.e., step S816 described above). The following describes the 5G channel list comparison process in step S816 with reference to fig. 10. Illustratively, the process includes the steps of:

at the receiving end, the first electronic device may perform the following steps:

s8161, the first channel negotiation module sends first 5G channel query information to the first Bluetooth module, and the first 5G channel query information is used for querying a 5G channel supported by the second electronic device.

In some embodiments, the first channel negotiation module may send, to the first bluetooth module, first 5G channel query information in response to the bluetooth connection establishment information received in step S8156, where the first 5G channel query information is used to query a list of 5G channels (or a 5G channel set) supported by the second electronic device.

S8162, the first Bluetooth module sends the first 5G channel inquiry information to the second Bluetooth module through the Bluetooth channel.

At the transmitting end, the second electronic device may perform the following steps:

and S8163, the second Bluetooth module sends the first 5G channel query information to the second channel negotiation module.

And S8164, the second channel negotiation module sends the first 5G channel query information to the second short-distance Wi-Fi module.

In some embodiments, the second channel negotiation module queries the second short-range Wi-Fi module for 5G channels supported by the second electronic device in response to the first 5G channel query information.

In some embodiments, when the second electronic device does not have a general interface for querying the 5G channel, the second channel negotiation module cannot successfully acquire the 5G channel query information that is successfully sent to the second short-range Wi-Fi module, and cannot successfully acquire the 5G channel supported by the second electronic device and fed back by the second short-range Wi-Fi module. At this time, the second channel negotiation module may generate 5G channel response information, where a 5G channel list included in the 5G channel response information is empty, that is, the 5G channel list does not include the 5G channel supported by the second electronic device.

It should be noted that, in practical application, when the clone application is a third-party application installed on the second electronic device, and the second electronic device does not have a general interface for querying the 5G channel, in the process of changing the switch and cloning, even if the clone application is installed on the second electronic device, the clone application cannot query the 5G channel list supported by the second electronic device, and further cannot enable the first electronic device to select the 5G channel for data transmission based on the intersection of the 5G channels supported by the two electronic devices. The data transmission method provided by the embodiment of the application can solve the problem that the 5G channel cannot be negotiated in the scene. Therefore, the present embodiment is mainly described in terms of a situation where the first electronic device cannot inquire about the 5G channel supported by the second electronic device (for example, a situation where the 5G channel list fed back by the second electronic device is empty).

S8165, when the second channel negotiation module does not inquire about the 5G channel supported by the second electronic device, generate first 5G channel response information, where the first 5G channel response information includes a 5G channel list supported by the second electronic device, and the 5G channel list is empty.

S8166, the second channel negotiation module sends the first 5G channel response information to the second Bluetooth module.

S8167, the second Bluetooth module sends the first 5G channel response information to the first Bluetooth module through the Bluetooth channel.

s8168, the first Bluetooth module sends the first 5G channel response information to the first channel negotiation module.

In some embodiments, the first channel negotiation module may obtain a 5G channel list supported by the second electronic device according to the 5G channel response information.

S8169, the first channel negotiation module sends second 5G channel query information to the first short-distance Wi-Fi module, and the second 5G channel query information is used for querying a 5G channel supported by the first electronic device.

S81610, the first short-range Wi-Fi module sends second 5G channel response information to the first channel, and the second 5G channel response information comprises a 5G channel list supported by the first electronic device.

It should be noted that the steps (i.e., step S8169 and step S81610) of the first electronic device acquiring the self-contained 5G channel list are not limited to be executed after acquiring the 5G channel list (corresponding to step S8161 to step S8168) of the second electronic device. In other embodiments, the operation of querying the own 5G channel list by the first electronic device may be performed simultaneously with the operation of querying the second electronic device 5G channel list, or may be performed before querying the second electronic device 5G channel list, which is not limited in this embodiment of the application.

S81611, the first channel negotiation module compares the 5G channel list supported by the first electronic device with the 5G channel list supported by the second electronic device, and determines that the 5G channel set supported by both of them is empty.

For example, assume that the list of 5G channels supported by the first electronic device is: 3638404446132153157161165, the list of 5G channels supported by the second electronic device is empty, that is [ ], and then the first channel negotiation module may determine the set of 5G channels supported by both of the first electronic device and the second electronic device as empty [ ] according to the list of 5G channels supported by the first electronic device and the list of 5G channels supported by the second electronic device. Or, when the first channel response information carries specific information (e.g., null) indicating that the 5G channel list of the second electronic device is empty, the first channel negotiation module may determine, according to the 5G channel list supported by the first electronic device and the 5G channel list supported by the second electronic device, that the 5G channel set jointly supported by both of the first and second electronic devices is empty.

When there is no intersection between the first electronic device and the second electronic device that supports the 5G channels (e.g., the list of 5G channels fed back by the second electronic device is empty), the first electronic device may query the second electronic device for the 5G capability (corresponding to step S819 described above). The 5G capability query process of the second electronic device in step S819 is described below with reference to fig. 11. Illustratively, the process includes the steps of:

s8181, the first channel negotiation module sends 5G capability inquiry information to the first Bluetooth module, and the 5G capability inquiry information is used for inquiring whether the second electronic device supports 5G capability.

In some embodiments, the first channel negotiation module may send the 5G capability query information to the first bluetooth module when determining that the set of 5G channels supported by both parties is empty in step S81611.

S8182, the first bluetooth module sends the 5G capability inquiry information to the second bluetooth module via the bluetooth channel.

and S8183, the second Bluetooth module sends 5G capability inquiry information to the second channel negotiation module.

And S8184, the second channel negotiation module sends the 5G capability inquiry information to the second short-distance Wi-Fi module.

It should be noted that the second electronic device may have a generic interface for 5G capability queries, such as Wi-FiManager: is5GHzBandSupported (). After receiving the 5G capability query information, the second channel negotiation module may send the 5G capability query information to the second short-range Wi-Fi module via the general interface to query whether the second electronic device supports the 5G capability.

And S8185, the second short-distance Wi-Fi module sends 5G capability response information to the second channel negotiation module.

Wherein the 5G capability response information includes a query result of whether the second electronic device supports the 5G capability.

And S8186, the second channel negotiation module sends 5G capability response information to the second Bluetooth module.

S8187, the second Bluetooth module sends the 5G capability response information to the first Bluetooth module.

Thereafter, at the receiving end, the first electronic device may perform the following steps:

s8188, the first bluetooth module sends 5G capability response information to the first channel negotiation module.

In some embodiments, the first channel negotiation module may obtain a query result of whether the second electronic device supports the 5G capability according to the 5G capability response information.

According to different query results, two situations can be distinguished: case 2A, the second electronic device does not support the 5G capability; case 2B, the second electronic device supports 5G capabilities.

Illustratively, as shown in fig. 12, a schematic flow chart of the first electronic device performing corresponding operations in case 2A and case 2B described above is shown.

S8212, the first channel negotiation module sends 5G hotspot opening information to the first short-distance Wi-Fi module, and the 5G hotspot opening information is used for indicating the first short-distance Wi-Fi module to open the 5G hotspot.

S8213, the first short-distance Wi-Fi module conducts 5G channel screening and opens a 5G hotspot.

In some embodiments, a short-range Wi-Fi module of the first electronic device may select a channel from a list of 5G channels supported by the first electronic device to attempt to establish a 5G Wi-Fi connection with the second electronic device. The first short-range Wi-Fi module may perform 5G channel screening in multiple ways, including: mode 1, according to the signal strength of the 5G channel supported by the first electronic device, selecting the 5G channel with the optimal signal strength; mode 2, randomly select a 5G channel, and so on.

It should be noted that, in this embodiment of the application, the process of the first electronic device attempting to open the 5G hotspot may include: selecting a 5G channel supported by the first electronic equipment to try to establish 5Gwi-Fi connection with the second electronic equipment within a preset time length; if the 5G Wi-Fi connection is not successfully established within the preset time length, the currently used 5G channel is possibly not supported by the second electronic equipment, the first electronic equipment is switched to the 2.4G hotspot, and the two parties transmit data through the 2.4G channel.

Or, if the 5G Wi-Fi connection is not successfully established within the preset time period, the first electronic device may attempt to establish the 5G Wi-Fi connection with the second electronic device on the 5G channels supported by the other first electronic devices within the new preset time period. According to the process, 5G channels supported by the first electronic device can be traversed to try the 5G Wi-Fi connection, if the Wi-Fi connection of the two sides on one 5G channel is successful in the trying process, the 5G channel can be used for data transmission subsequently, and efficient switch and cloning are achieved; and if the two parties cannot successfully establish the 5G Wi-Fi connection after traversing all the 5G channels supported by the first electronic equipment, the first electronic equipment is switched to the 2.4G hot spot, and the two parties transmit data through the 2.4G channels.

In a possible implementation manner, the second electronic device may use, for example, a 5G channel of a different country with the first electronic device, in which case, there may be a partial intersection between the 5G channels actually supported by the first electronic device and the second electronic device, and through the attempted connection process, a 5G Wi-Fi connection may be established on the 5G channels supported by both sides. Illustratively, the 5G channel open status in different countries is shown in table 2:

TABLE 2

Assuming that the 5G channel screened by the first short-range Wi-Fi module is also the 5G channel supported by the second electronic device, the first electronic device and the second electronic device may establish a 5G Wi-Fi connection on the 5G channel. Assuming that the 5G channel screened by the first short-range Wi-Fi module is a 5G channel that is not supported by the second electronic device, the first electronic device and the second electronic device cannot successfully establish a 5G Wi-Fi connection on the 5G channel.

For these two different cases, the first electronic device may perform the following steps:

It should be noted that, in conjunction with step S814, the second electronic device may periodically poll the 5G channel supported by the second electronic device to attempt to connect to the Wi-Fi hotspot corresponding to the Wi-Fi connection information. If the 5G channel where the 5G hotspot currently opened by the first electronic device is located (assuming that the channel code of the 5G channel is 36) is also the 5G channel actually supported by the second electronic device, when the second electronic device traverses to send the Wi-Fi connection request on the 5G channel (channel code is 36), the first electronic device may receive the Wi-Fi connection request on the 5G channel (channel code is 36), and then the two parties may successfully establish the 5G Wi-Fi connection. If the 5G channel where the currently opened 5G hotspot of the first electronic device is located (assuming that the channel code of the 5G channel is 40) is a 5G channel that is not supported by the second electronic device (that is, the set of 5G channels actually supported by both parties is empty), even if the second electronic device traverses all the 5G channels supported by itself to send the Wi-Fi connection request, the first electronic device cannot acquire the Wi-Fi connection request, and both parties cannot successfully establish the 5G Wi-Fi connection.

In some embodiments, the first electronic device and the second electronic device successfully establish a 5G Wi-Fi connection, and the first electronic device and the second electronic device may create a data transmission channel on a currently screened 5G channel of the first electronic device for data transmission. The creation process of the data channel may be as shown in fig. 14 below, and a specific process will be described below, which is not detailed here.

In some embodiments, if the first electronic device and the second electronic device do not successfully establish the 5G Wi-Fi connection, the first electronic device switches to the 2.4G hotspot and establishes a 2.4G connection with the second electronic device.

In some embodiments, the first channel negotiation module may obtain the notification information sent by the timer and reaching the preset time duration. In addition, the first channel negotiation module can also acquire whether the 5G Wi-Fi connection is successfully established or not through the first short-distance Wi-Fi module. The first channel negotiation module may determine that the timer exceeds a preset duration and the 5G Wi-Fi connection between the first electronic device and the second electronic device is not successfully established according to the notification information sent by the timer and the notification information sent by the first short-range Wi-Fi module. S82142, the first channel negotiation module sends the 5G hotspot closing information to the first short-range Wi-Fi module.

Wherein the 5G hotspot closing information is used for indicating the first short-range Wi-Fi module to close the 5G hotspot.

And S82143, in response to the 5G hotspot closing information, closing the 5G hotspot by the first short-distance Wi-Fi module.

Optionally, after the first short-range Wi-Fi module closes the 5G hotspot, notification information of closing the 5G hotspot may be sent to the first channel negotiation module.

S82144, the first channel negotiation module sends 2.4G hotspot opening information to the first short-range Wi-Fi module, where the 2.4G hotspot opening information is used to indicate that the first short-range Wi-Fi module opens a 2.4G hotspot.

S82145, responding to the 2.4G hotspot closing information, and opening the 2.4G hotspot by the first short-distance Wi-Fi module.

It should be understood that after the first electronic device starts a Wi-Fi hotspot (5G Wi-Fi hotspot or 2.4G Wi-Fi hotspot) through the above steps, the first electronic device may establish a data transmission channel with the second electronic device. For example, as shown in fig. 14, a schematic flowchart of establishing a data transmission channel between a first electronic device and a second electronic device may specifically include the following steps:

s8221, the first short-distance Wi-Fi module and the second short-distance Wi-Fi module establish Wi-Fi connection.

Illustratively, the process of establishing a Wi-Fi connection may include: the second short-distance Wi-Fi module periodically traverses a 5G channel supported by the second short-distance Wi-Fi module to send a Wi-Fi connection request message, wherein the Wi-Fi connection request message comprises connection information such as SSID (service set identifier) and passwords of a Wi-Fi hotspot of the first electronic equipment and is used for requesting to establish connection with the Wi-Fi hotspot corresponding to the SSID; after the first short-range Wi-Fi module starts the 5G hotspot, monitoring a Wi-Fi request message, and if the Wi-Fi connection request sent by the second electronic device can be monitored and it is determined that the second electronic device requests to establish 5G Wi-Fi connection with the first electronic device according to the Wi-Fi connection request message, then the two parties can establish 5G Wi-Fi connection on a 5G channel currently used by the second electronic device.

It should be noted that, in the embodiment of the present application, a sequence of executing steps S8222 to S8225 by the first electronic device and executing steps S8226 to S8229 by the second electronic device is not limited, in other words, after the Wi-Fi connection is established, the first electronic device and the second electronic device may independently execute respective operations.

For example, the data transmission interface displayed on the first electronic device may be as shown in fig. 16C, and correspondingly, the data transmission interface displayed on the second electronic device may be as shown in fig. 16D.

Illustratively, as shown in fig. 17, a schematic flow chart of a method for data transmission according to an embodiment of the present application is provided. The method comprises the following steps:

s1701, the first electronic device obtains a first channel list of the second electronic device, where the first channel list is used to indicate a first target frequency band channel supported by the second electronic device.

In some embodiments, the first electronic device may be a data receiving device in a switch clone scenario, and the second electronic device may be a data sending device in a switch clone scenario. The first electronic device is a device that supports the first target frequency band capability, that is, the first electronic device supports the capability of Wi-Fi communication on the first target frequency band. The first target frequency band may be a 5G frequency band, and the first target frequency band channel may be a 5G channel.

In some embodiments, the first channel list may correspond to the 5G channel response information in the foregoing embodiments, and may specifically be used to indicate the first target frequency band channel supported by the second electronic device.

In some embodiments, the first electronic device may receive a first operation input by a user, where the first operation may be, for example, a receiving end flow starting operation, such as operation 501 shown in fig. 5A; or may be an old device type selection operation entered by the user in the clone application, which may correspond to operation 502 shown in fig. 5B, for example.

In some embodiments, the first electronic device, in response to the first operation, may display a two-dimensional code for providing connection information of a Wi-Fi hotspot of the first electronic device, such as an SSID of the Wi-Fi hotspot and a corresponding password.

In some embodiments, the second electronic device may receive a second operation input by the user, where the second operation may be, for example, a two-dimensional code scanning interface starting operation of the second electronic device, where the two-dimensional code scanning interface may be, for example, as shown in fig. 6; responding to the second operation, and displaying a two-dimensional code scanning interface by the second electronic equipment; then, the second electronic device may scan the two-dimensional code displayed by the first electronic device through the two-dimensional code scanning interface, and then extract the SSID of the Wi-Fi hotspot and the password provided by the two-dimensional code (which may correspond to the two-dimensional code data in the above-mentioned embodiment, or Wi-Fi hotspot connection information).

In some embodiments, the first electronic device and the second electronic device may establish a bluetooth connection. For example, the first electronic device may send a bluetooth inquiry request in response to a two-dimensional code display operation or in response to an operation that a two-dimensional code is scanned; the second electronic device can respond to the two-dimension code scanning interface starting operation or respond to the two-dimension code scanning operation to carry out Bluetooth scanning; after that, the first electronic device and the second electronic device may establish a bluetooth connection based on a bluetooth communication standard, and a specific process of establishing the bluetooth connection may refer to the above related description, which is not described herein again.

Then, in some embodiments, the first electronic device may send, to the second electronic device via the bluetooth channel, first channel query information for querying a first target frequency band channel supported by the second electronic device; the second electronic equipment receives first channel inquiry information sent by the first electronic equipment through a Bluetooth channel; in response to the first channel query information, the second electronic device may query a first target frequency band channel supported by the second electronic device; thereafter, the second electronic device may transmit first channel response information to the first electronic device via the bluetooth channel, the first channel response information including the first channel list. Wherein the first channel query information may correspond to the 5G channel query information in the above embodiment.

In some embodiments, when the second electronic device fails to query the first target frequency band channel (for example, the second electronic device does not have a channel query generic interface, so that the first target frequency band channel cannot be queried), the first list includes the first target frequency band channel as empty, and the list of 5G channels that may correspond to the above-described feedback of the second electronic device is empty.

S1702, when an intersection of the first channel list and the second channel list is empty, the first electronic device starts a first target frequency band wireless fidelity Wi-Fi hotspot on the first channel, where the second channel list is used to indicate a first target frequency band channel supported by the first electronic device, and the first channel is one of the first target frequency band channels supported by the first electronic device.

In some embodiments, the first electronic device may obtain a second channel list, where the second channel list may be used to indicate the first target frequency band channel supported by the first electronic device itself. Specifically, the first channel negotiation module of the first electronic device may send second channel query information to the first short-range Wi-Fi module and receive second channel response information sent by the first short-range Wi-Fi module, where the second channel response information may include a second channel list.

In some embodiments, the first electronic device may obtain that an intersection of the first channel list and the second channel list is empty according to the first channel list and the second channel list. The intersection of the first channel list and the second channel list being empty may indicate that the first electronic device and the second electronic device do not have the first target frequency band channel commonly supported, that is, the first target frequency band channel set commonly supported by the first electronic device and the second electronic device is empty.

It should be understood that, in the embodiment of the present application, the reason why the intersection of the first channel list and the second channel list is empty may be, for example: the second electronic device does not successfully inquire the first target frequency band channel supported by the second electronic device.

In some embodiments, the process of the first electronic device opening the first target frequency band Wi-Fi hotspot on the first channel may include: when the intersection of the first channel list and the second channel list acquired by the first electronic device is empty, a first channel may be selected on a first target frequency band supported by the first electronic device itself, and then a first target frequency band Wi-Fi hotspot is opened on the first channel.

For example, the manner of selecting, by the first electronic device, the first channel from the first target frequency band supported by the first electronic device may include: when the intersection of the first channel list and the second channel list is empty, the first electronic equipment randomly selects a first channel from first target channels supported by the first electronic equipment; or, when the intersection of the first channel list and the second channel list is empty, the first electronic device selects a first channel from first target channels supported by the first electronic device according to the signal strength, and in this case, the first channel may be a channel with optimal signal strength, for example.

In some embodiments, the process of the first electronic device opening the first target frequency band Wi-Fi hotspot on the first channel may further include: when the first electronic device acquires that the intersection of the first channel list and the second channel list is empty, the first electronic device may send capability query information (which may correspond to the 5G capability query information in the foregoing embodiment) to the second electronic device, where the capability query information is used to query whether the second electronic device supports the first target frequency band capability; the second electronic device may obtain a query result of the first target frequency band capability in response to the capability query information, where the query result may be that the second electronic device supports the first target frequency band capability, and then send capability response information (which may correspond to the 5G capability response information in the foregoing embodiment) to the first electronic device, where the capability response information is used to indicate that the second electronic device supports the first target frequency band capability; then, the first electronic device receives capability response information sent by the second electronic device, and acquires that the second electronic device supports the first target frequency band according to the capability response information; and then, the first electronic equipment starts a first target frequency point Wi-Fi hotspot on the first channel.

It should be noted that, in this embodiment of the application, the second electronic device has a general interface for querying a capability of the first target frequency band (for example, 5G), and therefore, the first electronic device may obtain the capability of the first target frequency band of the second electronic device.

It should be further noted that, before the first electronic device attempts to establish the Wi-Fi connection with the second electronic device on the first channel, by querying the second electronic device for the first target frequency band capability, and after it is determined that the second electronic device supports the first target frequency band capability, establishing the Wi-Fi hotspot on the first channel, the possibility that the two parties successfully establish the Wi-Fi connection on the first target frequency band channel can be further improved.

S1703, when a Wi-Fi connection request message sent by a second electronic device through a first channel is obtained within a preset time, the first electronic device and the second electronic device establish Wi-Fi connection on the first channel, the Wi-Fi connection request message comprises an SSID of a Wi-Fi hotspot and a corresponding password, and the Wi-Fi connection request message is a polling message sent by the second electronic device on a first target frequency band channel supported by the second electronic device.

The SSID and the corresponding password included in the Wi-Fi connection request message can correspond to the first target frequency band Wi-Fi hotspot of the first electronic device. In other words, the Wi-Fi connection request message sent by the second electronic device is used to request connection with the first target frequency band Wi-Fi hotspot of the first electronic device.

In some embodiments, after acquiring the SSID of the Wi-Fi hotspot of the first electronic device and the corresponding password, the second electronic device may send a polling message for establishing the Wi-Fi connection request on a first target frequency band supported by the second electronic device. Specifically, the second electronic device may periodically traverse a first target channel supported by itself, attempting to establish a Wi-Fi connection (of the first target frequency band) with the first electronic device. For example, the second electronic device may broadcast a Wi-Fi connection request message on a certain first target frequency channel supported by the second electronic device, where the broadcast message of the Wi-Fi connection request may include an SSID and a password of a Wi-Fi hotspot of the first electronic device (of the first target frequency channel); if the Wi-Fi connection is not successfully established on the first target frequency band channel, switching to other first target frequency band channels to rebroadcast the Wi-Fi connection request message. When the Wi-Fi connection with the first electronic device is not successfully established after traversing all the first target frequency band channels supported by the second electronic device, the Wi-Fi connection request process may be performed again at a certain time interval.

In some embodiments, if the first electronic device does not receive the Wi-Fi connection request message sent by the second electronic device via the first channel within the preset time period, the first electronic device establishes a Wi-Fi connection (of a second target frequency band) with the second electronic device on a second channel, where the second channel is a certain second target frequency band channel supported by both the first electronic device and the second electronic device.

Wherein the second target frequency band may be a 2.4G frequency band.

S1704, the first electronic device receives data transmitted by the second electronic device via the first channel.

The data transmitted in the embodiment of the application can be the data selected by the user and required to be backed up to the first electronic device. The data transmission process can be referred to the specific description of the above embodiments.
