Disclosure of Invention

The embodiment of the application provides a data migration method and electronic equipment, which are used for reducing the data migration time by determining part of key target migration data from data to be migrated of old equipment and migrating the key target migration data to new equipment.

In a first aspect, an embodiment of the present application provides a data migration method, including: the first electronic device establishes connection with the second electronic device; the first electronic equipment determines a preset duration threshold for completing the data migration according to the data volume of the data to be migrated; the first electronic device determines target migration data according to a preset duration threshold; the target migration data is a part of the data to be migrated; the first electronic device displays a first interface; the first interface comprises a first option, the first option comprises a data volume of target migration data and target migration duration, the target migration duration is a duration required for estimating migration of the target migration data to the second electronic equipment, and the target migration duration is smaller than or equal to a preset duration threshold; in response to an operation input to the first interface, the first electronic device migrates the target migration data to the second electronic device.

The first interface may be a migration mode selection interface. In this way, according to the preset time threshold of the data to be migrated, the method and the device for migrating the target migration data determine a part of the data to be migrated from the data to be migrated as the target migration data, and quickly migrate the target migration data on the old device to the new device, so that the time required by migrating the target migration data to the new device is reduced, and a user can quickly use the new device in a short time.

In one possible implementation manner, the determining, by the first electronic device, a preset duration threshold for completing the data migration according to the data amount of the data to be migrated includes: the first electronic device estimates a first migration duration required for migrating the data to be migrated to the second electronic device according to the data quantity of the data to be migrated; the first electronic device determines a preset duration threshold corresponding to the first migration duration. In this way, the method for determining the preset time threshold by estimating the first migration time length for migrating the data to be migrated to the second electronic device can accurately measure the preset time threshold by combining the estimated first migration time length, namely accurately estimating the maximum value of the allowable migration time length when migrating the target migration data to the second electronic device.

In one possible implementation manner, the estimating, by the first electronic device, a first migration duration required for migrating the data to be migrated to the second electronic device according to the data amount of the data to be migrated includes: the method comprises the steps that first electronic equipment obtains data amounts respectively corresponding to various migration data included in data to be migrated; the first electronic device estimates a first migration duration required for migrating the data to be migrated to the second electronic device according to the data volume of each migration data in the plurality of migration data and the corresponding migration speed. Therefore, the migration speed of different types of migration data in the actual data migration process may be different, and therefore, the first migration duration can be estimated more accurately by combining the data quantity of each type of migration data and the corresponding migration speed.

In one possible implementation manner, the estimating, by the first electronic device, a first migration duration required for migrating the data to be migrated to the second electronic device according to the data amount of each of the plurality of migration data and the corresponding migration speed includes: the first electronic equipment takes the data volume of each migration data and the ratio of the corresponding migration speed as the corresponding migration duration of each migration data; the first electronic equipment sums the migration duration corresponding to each migration data in the plurality of migration data to obtain a first migration duration of the data to be migrated.

In a possible implementation manner, the determining, by the first electronic device, a preset duration threshold corresponding to the first migration duration includes: the first electronic equipment determines a data model corresponding to data to be migrated according to a time interval in which a first migration time is located; the first electronic device determines a preset duration threshold corresponding to the data model. Therefore, the method and the device can determine the preset time length threshold based on the preset data model, and the determination mode of the preset time length threshold is simpler.

In one possible implementation manner, the determining, by the first electronic device, target migration data according to a preset duration threshold includes: the method comprises the steps that first electronic equipment determines the data quantity of basic key data in data to be migrated; the first electronic device estimates a second migration duration required for migrating the basic key data to the second electronic device according to the data quantity of the basic key data; and the first electronic equipment determines target migration data according to the second migration duration and a preset duration threshold. Therefore, the target migration data can be determined by comparing the second migration duration of the basic key data with the preset duration threshold value, so that more important data are determined as the target migration data to migrate to the second electronic equipment on the basis that the target migration duration of the finally determined target migration data is smaller than or equal to the preset duration threshold value, and the target migration data can be directly used by a user when the user uses the second electronic equipment after the machine change, thereby improving the use experience of the user.

In one possible implementation manner, the determining, by the first electronic device, target migration data according to the second migration duration and the preset duration threshold includes: and under the condition that the second migration time length is greater than a preset time length threshold value, the first electronic equipment takes part of key data in the basic key data as target migration data. Therefore, when the second migration time is longer than the preset time threshold, it is indicated that all basic key data cannot be migrated to the second electronic device within the preset time threshold, and therefore, part of key data in the basic key data needs to be used as target migration data, so that the migration time required when the target migration data is migrated to the second electronic device is shorter, and the purpose of quick machine change is achieved.

In one possible implementation manner, the first electronic device uses part of the basic key data as target migration data, including: the first electronic equipment acquires the priority of each key data in the basic key data; and the first electronic equipment sequentially removes the key data in the basic key data according to the order of the priority from low to high until the migration duration of the residual key data is less than or equal to a preset duration threshold value, and takes the residual key data as target migration data. Therefore, because the basic key data with higher priority is the data which is easier to use by the user, some basic key data with higher priority can be used as target migration data to migrate to the second electronic equipment, and the basic key data with higher priority can be used by the user when the second electronic equipment is used after the quick change is realized.

In one possible implementation manner, the determining, by the first electronic device, target migration data according to the second migration duration and the preset duration threshold includes: under the condition that the second migration time length is smaller than a preset time length threshold value, the first electronic device determines recommended application data in the data to be migrated; the first electronic device takes the basic key data and the recommended application data as target migration data. Therefore, when the second migration duration is smaller than the preset duration threshold, it is indicated that all basic key data can be migrated to the second electronic device within the preset duration threshold, and therefore when the basic key data is migrated to the second electronic device, recommended application data can be migrated to the second electronic device together, and when a user uses the second electronic device after changing the machine, application programs corresponding to the recommended application data can be directly used, and the use experience of the user is improved.

In one possible implementation manner, the determining, by the first electronic device, recommended application data in the data to be migrated includes: the method comprises the steps that first electronic equipment obtains priority of each application data in data to be migrated; the first electronic equipment sequentially adds application data on the basis of basic key data according to the order of priority from high to low until the migration time length of the added N application data and basic key data is greater than a preset time length threshold value, and takes the added first N-1 application data as recommended application data; n is a positive integer. Therefore, the application data with high priority is application data which is easier to use by the user after the machine change, so that the application data with high priority can be used as recommended application data to be migrated to the second electronic equipment, and the use experience of the user after the machine change is improved.

In one possible implementation manner, the first electronic device obtains a priority of each application data in the data to be migrated, including: the method comprises the steps that first electronic equipment obtains using parameters of application programs corresponding to application data; the usage parameters include a usage duration and/or a usage frequency; the first electronic device determines the priority of each application data according to the use parameters. In this way, the priority of each application data in the data to be migrated can be accurately determined according to the actual use condition of the user.

In one possible implementation manner, the first electronic device determines the priority of each application data according to the usage parameter, including: and the first electronic equipment performs weighted summation on the using duration and the using frequency of the application program corresponding to each application data to obtain the priority of each application data. In this way, the priority of the application data is determined by combining the use duration and the use frequency, so that the finally determined priority of each application data is more accurate.

In one possible implementation, the first interface further includes a first control; in response to an operation input to the first interface, the first electronic device migrates target migration data to the second electronic device, including: responding to the operation of the first control input in the first interface, and displaying a second interface by the first electronic equipment; in response to operation of the second control input in the second interface, the first electronic device migrates the target migration data to the second electronic device. The first control can be a first mode selection control, the second interface can be a first data selection interface, and the second control can be a first migration control.

In one possible implementation, after the first electronic device migrates the target migration data to the second electronic device, the method further includes: under the condition that all target migration data are migrated to the second electronic equipment, the first electronic equipment is disconnected with the second electronic equipment; under the condition that connection is established with the second electronic equipment again, the first electronic equipment displays a prompt box; the prompt box comprises a data list of non-migrated data and a confirmation control, wherein the non-migrated data is data except target migration data in the data to be migrated; in response to operation of the validation control input, the first electronic device migrates the non-migrated data to the second electronic device. Therefore, the method and the device can migrate the data which are not migrated last time to the second electronic device under the condition that the first electronic device and the second electronic device are connected again, so that the use experience of a user is further improved.

In addition, the embodiment of the application also provides a data migration method, which comprises the following steps: the first electronic device establishes connection with the second electronic device; when the data volume of the data to be migrated in the first electronic equipment is larger than a preset threshold, the first electronic equipment determines first target migration data which is part of the data to be migrated; the first electronic device displays a first option in a first target interface, wherein the first option comprises the data volume of first target migration data and first target migration duration, and the first target migration duration is a duration required by estimating migration of the first target migration data to the second electronic device; when the data volume of the data to be migrated in the first electronic equipment is smaller than or equal to a preset threshold value, the first electronic equipment determines second target migration data which are part of the data to be migrated, and the data volume of the second target migration data is smaller than that of the first target migration data; the first electronic device displays a second option in the second interface, wherein the second option comprises the data volume of second target migration data and second target migration duration, and the second target migration duration is a duration required by estimating to migrate the second target migration data to the second electronic device.

The preset threshold value can be set according to actual conditions, the first electronic device can be old device, and the second electronic device can be new device. In this way, when the data volume of the data to be migrated in the old equipment is larger than the preset threshold value, the data volume of the data to be migrated in the old equipment is larger, and the first target migration data can be determined from the data to be migrated; when the data amount of the data to be migrated in the old equipment is smaller than or equal to the preset threshold value, the data amount of the data to be migrated in the old equipment is smaller, and the second target migration data can be determined from the data to be migrated. The second target migration data has a smaller data volume than the first target migration data.

Therefore, the first electronic device can migrate part of data in the data to be migrated to the second electronic device, and quick machine changing is realized. When the data amount of the data to be migrated in the first electronic device is more, the target migration data to be migrated to the second electronic device for the first time is more; when the data volume of the data to be migrated in one electronic device is smaller, the target migration data to be migrated to the second electronic device for the first time is smaller.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be implemented independently or combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

In the following embodiments, the purpose of realizing convenient phone exchange through data migration will be described by taking the first electronic device 100 and the second electronic device 200 as mobile phones as examples.

Fig. 4 is a flowchart of a first electronic device migrating target migration data to a second electronic device according to an embodiment of the present application. Referring to fig. 4, the corresponding data migration method specifically may include the following steps:

in step 401, the first electronic device establishes a connection with the second electronic device.

In some embodiments, a cloning application, such as an "change cloning" application, is installed on both the first electronic device and the second electronic device, and may be used to interact with the user.

When the user needs to migrate data on a first electronic device (e.g., an old device) to a second electronic device (e.g., a new device), the user may click on an icon corresponding to a cloned application displayed on a main interface of the second electronic device, and the second electronic device displays a first cloned interface 501 as shown in (a) of fig. 5 in response to the user's click operation on the cloned application icon. The first cloning interface 501 is used for displaying the relevant description of the clone function of the exchange machine, such as "fast migration of data of contacts, photos, schedules, etc. to new devices" shown in fig. 5 (a); in addition, the first clone interface 501 also displays a device type option, as shown in fig. 5 (a), which is a new device (received data) option, and which is an old device (transmitted data) option.

The user may click on the "this is new device (receive data)" option, and the second electronic device may display a second clone interface 502 as shown in fig. 5 (b) in response to the user clicking on the "this is new device (receive data)" option. The second clone interface 502 includes a plurality of device types of the first electronic device for the user to select, for example, a glowing old device type (i.e., a type corresponding to when the first electronic device is a glowing device), an Android old device type (i.e., a type corresponding to when the first electronic device is other Android devices than the glowing device), and an iOS old device type (i.e., a type corresponding to when the first electronic device is an iPhone, iPad, or the like using the iOS system).

In some embodiments, assuming that the device type of the first electronic device is a glowing old device type, the user may click on an option corresponding to the glowing old device type, the second electronic device may respond to a click operation of the user on the option corresponding to the glowing old device type, and the second electronic device may display a third clone interface 503 as shown in fig. 5 (c). The third clone interface 503 includes a hotspot two-dimensional code 5031 provided by the second electronic device for use in establishing a Wi-Fi connection with the first electronic device, and instructions directing the user to perform a connection operation on the first electronic device, such as "open ' change clone at old device", select ' this is old device ', scan the underlying two-dimensional code to establish a connection.

In order to prevent that the Wi-Fi connection between the first electronic device and the second electronic device may not be successfully established when the Wi-Fi connection between the first electronic device and the second electronic device is established through the hotspot two-dimensional code 5031, the third cloning interface 503 further displays a prompt message for manually establishing the Wi-Fi connection between the first electronic device and the second electronic device, such as "if the two-dimensional code cannot be connected, please click the manual connection under the old device scanning interface, connect the WLAN below", and the connection information and the password of the WLAN. In addition, for the case where the first electronic device does not install the clone application, the third clone interface 503 also displays an installation link of the "clone switch" application for guiding the user to install the "clone switch" application on the first electronic device.

Accordingly, the user may click on an icon corresponding to the clone application displayed on the main interface of the first electronic device, and the first electronic device displays a fourth clone interface 601 as shown in (a) of fig. 6 in response to the click operation of the clone application icon by the user. The fourth clone interface 601 is for displaying a related description of the change clone function such as "fast transfer of data of contacts, photos, schedules, etc. to a new device" as shown in fig. 6 (a), and the fourth clone interface 601 also displays a device type option such as "this is a new device (receive data)" option as shown in fig. 6 (a), and "this is an old device (transmit data)" option.

The user may click on the "this is old device (send data)" option, and the first electronic device may display a fifth clone interface 602 as shown in fig. 6 (b) in response to the user clicking on the "this is old device (send data)" option. The fifth clone interface 602 includes a scan window 6021 of the hotspot two-dimensional code, and instructions for directing the user to perform a connection operation on the second electronic device, such as "please open a 'change clone' on the new device, select 'this is that the new device' obtains the hotspot two-dimensional code.

The user may align the scanning window 6021 of the hotspot two-dimensional code displayed on the first electronic device with the hotspot two-dimensional code 5031 shown in (c) in fig. 5, so that the first electronic device scans the hotspot two-dimensional code 5031 displayed on the third cloning interface 503 of the second electronic device, and the first electronic device is connected to the hotspot of the second electronic device, so as to establish Wi-Fi connection between the first electronic device and the second electronic device. The Wi-Fi connection described above may also be referred to as a Wi-Fi peer-to-peer (P2P) connection.

When the scan window 6021 of the hot spot two-dimensional code displayed on the first electronic device is used to scan the hot spot two-dimensional code 5031 displayed on the third clone interface 503 of the second electronic device, the first electronic device jumps to the sixth clone interface 603 shown in fig. 6 (c). The sixth cloning interface 603 includes a diagram for showing the current connection process of the first electronic device and the second electronic device, such as dynamic ripple of sound waves, which may be displayed in the sixth cloning interface 603 in a flashing form, which is not limited by the embodiment of the present application.

It should be noted that the interfaces shown in fig. 5 (a) to 5 (c) and the interfaces shown in fig. 6 (a) to 6 (c) are only examples. In practical applications, the interface involved in the connection process of the first electronic device and the second electronic device may further include other more or less contents, which is not limited in the embodiment of the present application.

In addition, in other embodiments, the first electronic device and the second electronic device may also be connected by other connection manners besides the Wi-Fi connection, for example, the first electronic device and the second electronic device may also be connected by NFC or bluetooth.

Or, the first electronic device and the second electronic device may be connected by other connection modes besides the mode of scanning the two-dimensional code, for example, connection is established by adopting modes such as proximity discovery or touch discovery. When the user holds the second electronic device and gradually approaches the first electronic device, the first electronic device may scan a broadcast message sent by the second electronic device, the first electronic device determines a distance between the first electronic device and the second electronic device according to a signal intensity of the scanned broadcast message, and when the distance between the first electronic device and the second electronic device is smaller than a preset distance, a pairing connection interface pops up on a display screen of the first electronic device, and the user may perform a pairing connection operation on the pairing connection interface to establish connection between the first electronic device and the second electronic device.

Step 402, the first electronic device obtains data amounts respectively corresponding to a plurality of kinds of migration data included in the data to be migrated.

In some embodiments, in a process of establishing connection between the first electronic device and the second electronic device, or after the first electronic device and the second electronic device are successfully established, the migration duration estimation module in the clone application installed on the first electronic device may acquire the data amount corresponding to each piece of migration data in the data to be migrated stored in the first electronic device by calling an API interface provided by the application program framework layer.

For example, the data to be migrated stored in the first electronic device may include: contact, short message, call record, document, system setting, memo, schedule, data of each third party application, pictures, video and other migration data.

It should be noted that, the third party application is an application program different from the native application, and the third party application refers to an application program that is produced by a third party and requires a user to install on the electronic device. While the native application refers to an application program pre-installed on the electronic device, and belongs to an application program of the electronic device.

For each migration data included in the data to be migrated, the migration duration estimation module in the clone application can acquire data amounts corresponding to a plurality of different migration data included in the data to be migrated, namely, data amounts corresponding to each migration data included in the data to be migrated, by calling different API interfaces provided by the application program framework layer, and the data amounts correspond to one API interface respectively.

By way of example, the migration duration estimation module may obtain the data size of the contact by calling a first interface A1 provided by the application framework layer; the migration duration estimation module can also acquire the data volume of the short message by calling a second interface A2 provided by the application program framework layer; the migration duration estimation module can also acquire the data quantity corresponding to the data of one of the third party applications by calling a third interface A3 provided by the application program framework layer.

The migration duration estimation module can classify different migration data after acquiring data amounts respectively corresponding to each migration data included in the data to be migrated. By way of example, the respective migration data included in the data to be migrated may be divided into the following three categories, which are structured data, application data, and media file data, respectively.

Structured data refers to data represented and stored using a relational database in a two-dimensional form, and is generally characterized in that the data is represented in units of rows, one row represents information of one entity, and attributes of each row of data are identical, or the structured data may be represented in units of columns, one column represents information of one entity, and attributes of each column of data are identical. For example, contacts, messages, schedules, etc. in the data to be migrated all belong to the structured data.

The application data refers to data of third party applications such as social applications, shopping applications, and gaming applications. The data of the third party application may include an installation package of the third party application, a login account of the third party application, a login password, data collected in the third party application, and some usage records. For example, for a social class application, the usage record may be a chat record or the like.

Media file data refers to data such as photographs, video, audio, or documents.

The above description describes three types of migration data, which are included in the data to be migrated, as structured data, application data, and media file data. It will be appreciated that the data types of the data to be migrated after being partitioned are not limited to the three types of data described above, but may include other more or fewer data types, etc. In addition, the data to be migrated is not limited to the above-described data type classification.

It should be noted that, because different types of migration data in the data to be migrated are located in different folders when being stored, when the migration duration estimation module obtains the data amounts corresponding to the migration data included in the data to be migrated, the folder names or storage paths where the migration data are located can be known correspondingly, and therefore the migration duration estimation module can perform type division on the migration data included in the data to be migrated according to the folder names or storage paths where the migration data are located.

Illustratively, if the structured data is located in the first folder B1, the application data is located in the second folder B2, and the media file data is located in the third folder B3. Therefore, when the folder in which a certain migration data in the data to be migrated is located is the first folder B1, the migration data belongs to the structured data; when the folder in which another migration data in the data to be migrated is located is a second folder B2, the migration data belongs to the application data; when the folder in which the migration data is located is the third folder B3, the migration data belongs to the media file data.

Therefore, after classifying different migration data, the migration duration estimation module sums the data amounts corresponding to the migration data of the same type to obtain the data amounts corresponding to the migration data of the same type. Specifically, summing the data volume corresponding to each migration data included in the structured data to obtain the data volume corresponding to the structured data; summing the data quantity corresponding to each migration data included in the application data to obtain the data quantity corresponding to the application data; and summing the data quantity corresponding to each migration data included in the media file data to obtain the data quantity corresponding to the media file data.

In summary, the migration duration estimation module in the cloning application can acquire the data amounts respectively corresponding to the three types of migration data included in the data to be migrated through the mode.

In step 403, the first electronic device uses the data size of each type of migration data and the ratio of the corresponding migration speed as the migration duration corresponding to each type of migration data.

In some embodiments, migration speeds corresponding to various types of migration data may be stored in advance, and the migration speeds may be set according to empirical values. For example, the migration speed corresponding to the structured data is 20MB/s, the migration speed corresponding to the application data is 7.5MB/s, and the migration speed corresponding to the media file data is 20MB/s.

In other embodiments, the first electronic device may also measure and calculate migration speeds corresponding to various types of migration data in real time, so that the first migration duration obtained by final calculation is more accurate. The first electronic device may send a test data packet of each data type to the second electronic device, where the second electronic device may return response information for the test data packet to the first electronic device, where the response information includes a first time when the second electronic device receives the test data packet, and the first electronic device may obtain a second time when the test data packet is sent, calculate a time difference between the first time and the second time, and finally obtain a migration speed of each migration data according to a ratio of a data amount of the test data packet to the time difference.

The migration duration estimation module in the clone application installed on the first electronic device can take the ratio of the data volume of each migration data and the corresponding migration speed as the corresponding migration duration of each migration data. For example, as shown in fig. 7, the migration duration estimation module uses the ratio of the data amount corresponding to the structured data and the corresponding migration speed as the migration duration corresponding to the structured data; the migration duration estimation module takes the data quantity corresponding to the application data and the ratio of the corresponding migration speeds as the migration duration corresponding to the application data; the migration duration estimation module takes the ratio of the data quantity corresponding to the media file data and the corresponding migration speed as the migration duration corresponding to the media file data.

For example, the data amount corresponding to the structured data is H1, and the units thereof are MB, and the migration duration T1 = H1/20 corresponding to the structured data is in seconds; correspondingly, the data quantity corresponding to the application data is H2, the units are MB, and the migration time length T2 = H2/7.5 corresponding to the application data is seconds; and the data amount corresponding to the media file data is H3, and the units are MB, and the migration duration T3 = H3/20 corresponding to the media file data is in seconds.

Step 404, the first electronic device sums the migration durations corresponding to each of the plurality of migration data to obtain a first migration duration of the data to be migrated.

In some embodiments, the migration duration estimation module sums the migration durations corresponding to each type of migration data after calculating the migration duration corresponding to each type of migration data in the three types of migration data, so as to obtain a first migration duration of the data to be migrated.

As shown in fig. 7, the first migration duration of the data to be migrated is determined by a migration duration corresponding to the structured data, a migration duration corresponding to the application data, and a migration duration corresponding to the media file data. The first migration duration is a duration required when all data to be migrated in the first electronic device are migrated to the second electronic device.

For example, the migration duration corresponding to the structured data is T1, the migration duration corresponding to the application data is T2, and the migration duration corresponding to the media file data is T3, where the first migration duration t0=t1+t2+t3 of the data to be migrated.

For example, the migration duration T1 corresponding to the structured data is 15 seconds, the migration duration T2 corresponding to the application data is 3000 seconds, the migration duration T3 corresponding to the media file data is 527 seconds, and then the first migration duration T0 of the data to be migrated is 3542 seconds, which is approximately equal to 59 minutes.

In another implementation manner, the first electronic device may also obtain a data amount corresponding to each piece of migration data included in the data to be migrated, calculate a ratio of the data amount of each piece of migration data to a migration speed of a type to which the data is attached, obtain a migration duration of each piece of migration data, and finally sum migration durations of all pieces of migration data to obtain a first migration duration of the data to be migrated.

Step 405, the first electronic device determines a data model corresponding to the data to be migrated according to a duration interval in which the first migration duration is located.

In some embodiments, after the migration duration estimation module in the clone application calculates the first migration duration of the data to be migrated, the data model decision module in the clone application may determine, by using a duration interval in which the first migration duration is located, a data model corresponding to the data to be migrated.

As shown in fig. 8, the data models corresponding to the data to be migrated include a light model, a moderate model and a heavy model, and the duration interval corresponding to the light model is within 30 minutes, the duration interval corresponding to the moderate model is 30 minutes to 60 minutes, and the duration interval corresponding to the heavy model is more than 60 minutes.

When the first migration duration is less than or equal to 30 minutes, the data model decision module determines that the data model corresponding to the data to be migrated is a light module; when the first migration time is longer than 30 minutes and smaller than 60 minutes, the data model decision module determines that a data model corresponding to data to be migrated is a moderate model; and when the first migration time is longer than or equal to 60 minutes, the data model decision module determines a data model corresponding to the data to be migrated as a weight model.

For example, when the first migration duration T0 of the data to be migrated is 59 minutes and is greater than 30 minutes and less than 60 minutes, the data model decision module determines that the data model corresponding to the data to be migrated is a moderate model.

It should be noted that, the duration interval corresponding to each data model described in the foregoing process is only an optional example, and in practical application, the duration interval corresponding to each data model includes but is not limited to the foregoing example, for example, the duration interval corresponding to the light model may be within 40 minutes, the duration interval corresponding to the medium model may be between 40 minutes and 80 minutes, and the duration interval corresponding to the heavy model may be above 80 minutes.

Furthermore, the three data models described in the above process are also merely one alternative example, and in practical applications, classification of the data models is not limited to the above examples. For example, the data model corresponding to the data to be migrated may also include a first data model, a second data model, a third data model and a fourth data model, where the duration intervals corresponding to the four data models do not overlap.

Therefore, in combination with the steps 402 to 405, it can be seen that the embodiment of the present application predicts the first migration duration of the data to be migrated according to the data amount of the data to be migrated, and determines the data model based on the first migration duration.

In another possible implementation, the data model may also be determined directly from the data volume of the data to be migrated. Specifically, a data model corresponding to the data to be migrated can be determined according to a data volume interval in which the data volume of the data to be migrated is located.

For example, the data volume section corresponding to the light model is within 8G, the data volume section corresponding to the medium model is 8G to 20G, and the data volume section corresponding to the heavy model is 20G or more. When the data volume of the data to be migrated is smaller than or equal to 8G, the data model decision module determines that the data model corresponding to the data to be migrated is a light module; when the data volume of the data to be migrated is more than 8G and less than 20G, the data model decision module determines that the data model corresponding to the data to be migrated is a moderate model; when the data volume of the data to be migrated is larger than or equal to 20G, the data model decision module determines a data model corresponding to the data to be migrated as a weight model.

In step 406, the first electronic device determines a preset duration threshold corresponding to the data model.

In some embodiments, a duration threshold corresponding to each data model is preset, where the duration threshold represents a maximum value of allowable migration duration when the target migration data is migrated to the second electronic device. For example, the duration threshold for the light model is 10 minutes, the duration threshold for the medium model is 20 minutes, and the duration threshold for the heavy model is 40 minutes.

Therefore, after the data model decision module in the cloning application decides the data model corresponding to the data to be migrated, the preset duration threshold corresponding to the data model can be further determined. For example, when the data model corresponding to the data to be migrated is a light model, the data model decision module may determine that the corresponding preset duration threshold is 10 minutes; when the data model corresponding to the data to be migrated is a moderate model, the data model decision module can determine that the corresponding preset duration threshold value is 20 minutes; when the data model corresponding to the data to be migrated is a gravity model, the data model decision module can determine that the corresponding preset duration threshold is 40 minutes.

In other embodiments, the preset coefficient may be preset, and after the migration duration estimation module in the cloning application calculates the first migration duration of the data to be migrated, the data model decision module in the cloning application may directly use the product of the first migration duration and the preset coefficient as the preset duration threshold. The preset coefficient is a positive number less than 1.

For example, the preset coefficient is 0.4, and the preset duration threshold may be 12 minutes when the first migration duration is 30 minutes, and 24 minutes when the first migration duration is 60 minutes.

In still other embodiments, a relationship comparison table between different data volume intervals and time length thresholds may be preset, and after the data volume of the data to be migrated is obtained, the corresponding preset time length threshold is found according to the data volume interval in which the data volume of the data to be migrated is located.

In step 407, the first electronic device obtains the data amount of the basic key data in the data to be migrated.

In some embodiments, after determining the preset duration thresholds corresponding to all the data to be migrated, the application recommendation calculation module in the clone application may determine the basic key data from the data to be migrated.

The basic key data refers to important data in the data to be migrated. The basic key data comprise key data such as contacts, short messages, call records, documents, system settings, memorandum, schedules and the like.

It should be noted that the basic key data is several data set empirically in advance, and the basic key data is not necessarily associated with the above three types of data, i.e., structured data, application data, and media file data. In some embodiments, part of the data in the underlying critical data may be structured data, while another part of the data may be media file data; alternatively, in other embodiments, the underlying critical data may be part or all of the structured data.

In step 408, the first electronic device predicts a second migration duration of the basic key data according to the data amount of the basic key data.

In some embodiments, after the application recommendation calculation module obtains the data amount of the basic key data in the data to be migrated, the migration duration estimation module in the cloning application may estimate the second migration duration of the basic key data according to the data amount of the basic key data. The second migration duration refers to a duration required when all basic key data in the first electronic device are migrated to the second electronic device.

The method for estimating the second migration duration of the basic key data may be similar to the method for estimating the first migration duration of the data to be migrated described in steps 402 to 404. And classifying each data in the basic key data, calculating migration time lengths corresponding to each type of data in the basic key data, and finally summing the migration time lengths corresponding to each type of data in the basic key data to obtain a second migration time length of the basic key data. To avoid repetition, the method for estimating the second migration duration of the underlying critical data is not described in detail herein.

Or when calculating the first migration duration of the data to be migrated in the above process, if a mode of sequentially calculating the migration duration of each migration data and summing the migration durations of all migration data is adopted, when estimating the second migration duration of the basic key data, the step can obtain the migration duration of each basic key data in the calculated migration duration of each migration data, and finally sum the migration durations of each basic key data to obtain the second migration duration of the basic key data.

In step 409, the first electronic device determines whether the second migration duration is less than a preset duration threshold.

In some embodiments, the migration duration estimation module in the clone application may compare the second migration duration with the preset duration threshold determined in step 406 above after estimating the second migration duration of the basic key data. When the second migration time is greater than the preset time threshold, the application recommendation calculation module in the cloned application performs the following step 410; when the second migration duration is less than the preset duration threshold, the application recommendation calculation module in the cloned application performs the following steps 411 and 412. For the case where the second migration duration is equal to the preset duration threshold, the basic key data may be directly used as the target migration data, which is not shown in fig. 4.

For example, taking a data model corresponding to the data to be migrated as a light model, and the duration threshold corresponding to the light model is 10 minutes, so that the second migration duration corresponding to the basic key data can be compared with the preset duration threshold for 10 minutes; taking a data model corresponding to data to be migrated as a middle model as an example, and comparing a second migration duration corresponding to basic key data with a preset duration threshold for 20 minutes if a duration threshold corresponding to the middle model is 20 minutes; taking the data model corresponding to the data to be migrated as a gravity model as an example, if the duration threshold corresponding to the gravity model is 40 minutes, the second migration duration corresponding to the basic key data can be compared with the preset duration threshold for 40 minutes.

In step 410, the first electronic device uses part of the basic key data as the target migration data when the second migration time is longer than the preset time threshold.

In some embodiments, when the second migration time period is greater than the preset time period threshold, it is indicated that the time period required for all the basic key data in the first electronic device to migrate to the second electronic device is longer, and it cannot be satisfied that all the basic key data are migrated to the second electronic device within the preset time period threshold. Therefore, the application recommendation calculation module in the clone application can take part of the key data in the basic key data as target migration data and remove the rest key data in the basic key data, so that the target migration duration required by the target migration data when migrating to the second electronic device is estimated to be smaller than or equal to a preset duration threshold.

The target migration data is part of the key data in the basic key data, and the basic key data is part of the data in the data to be migrated, so that the target migration data can be understood as part of the data in the data to be migrated.

In one possible implementation manner, when the application recommendation calculation module takes part of the key data in the basic key data as the target migration data, the key data serving as the target migration data, namely the key data serving as the target migration data, which is higher in priority, can be determined according to the priority of each key data in the basic key data.

Specifically, the first electronic device obtains the priority of each key data in the basic key data; and the first electronic equipment sequentially removes the key data in the basic key data according to the order of the priority from low to high until the migration duration of the residual key data is less than or equal to a preset duration threshold value, and takes the residual key data as target migration data.

The priority of each key data in the basic key data is determined in advance, and the priority of each key data can be determined according to the priority order fed back by the user. For example, the first electronic device may receive the priority order of each key data input by the user, or may count the priority orders of each key data input by a plurality of users in advance, thereby obtaining the priority of each key data.

In some embodiments, the basic key data includes key data such as contacts, sms, call records, documents, system settings, memos, schedules, etc., where the priority of each key data is in the order from high to low: contacts, memos, messages, call records, schedules, system settings, documents.

Therefore, after the application recommendation calculation module acquires the priority of each key data in the basic key data, the application recommendation calculation module sequentially removes the key data in the basic key data according to the order of the priority from low to high, and judges whether the migration duration of the residual key data is smaller than or equal to a preset duration threshold value after removing one key data. When the migration time length of the residual key data is longer than a preset time length threshold value, the application recommendation calculation module continues to remove the key data according to the order of the priority from low to high until the migration time length of the residual key data is smaller than or equal to the preset time length threshold value, and the residual key data is used as target migration data.

For example, the priorities of the respective key data are in order from high to low: contacts, memos, messages, call records, schedules, system settings, documents. Therefore, under the condition that the second migration time length is greater than the preset time length threshold, the application recommendation calculation module firstly removes the document in the basic key data, and judges whether the migration time length corresponding to the residual key data (namely, the residual key data at the moment comprises contacts, memos, short messages, call records, schedules and system settings) is less than or equal to the preset time length threshold. When the migration time length corresponding to the residual key data is less than or equal to a preset time length threshold value, setting contacts, memos, short messages, call records, schedules and systems as target migration data; and when the migration time length corresponding to the residual key data is greater than the preset time length threshold, the application recommendation calculation module continues to remove the system settings in the basic key data, and judges again whether the migration time length corresponding to the residual key data (namely, the residual key data at this time comprises contacts, memos, short messages, call records and schedules) is less than or equal to the preset time length threshold. According to the mode, key data in the basic key data are sequentially removed until the migration duration of the residual key data is smaller than or equal to a preset duration threshold value, and the residual key data are used as target migration data.

It should be noted that, in the process of determining whether the migration duration of the remaining critical data is less than or equal to the preset duration threshold after removing one critical data, the method for estimating the migration duration of the remaining critical data is similar to the method for estimating the first migration duration of the data to be migrated described in steps 402 to 404, so that repetition is avoided and redundant description is omitted.

In step 411, the first electronic device determines recommended application data in the data to be migrated if the second migration duration is less than the preset duration threshold.

In some embodiments, when the second migration duration is less than the preset duration threshold, it is indicated that the duration required for all the basic key data in the first electronic device to be migrated to the second electronic device is shorter, and all the basic key data can be migrated to the second electronic device within the preset duration threshold. Therefore, in order to further improve the use experience of the user when using the second electronic device after the machine change, the application recommendation calculation module in the clone application can determine recommended application data from the data to be migrated, so that the recommended application data can be migrated to the second electronic device together when basic key data is migrated to the second electronic device later, and the user can directly use application programs corresponding to the recommended application data when using the second electronic device after the machine change, thereby improving the use experience of the user.

In one possible implementation manner, when determining recommended application data from data to be migrated, the application recommendation calculation module may determine recommended application data according to priorities of application data in the data to be migrated, where the recommended application data is application data with a higher priority in the application data.

Specifically, the first electronic device obtains the priority of each application data in the data to be migrated; the first electronic equipment sequentially adds application data on the basis of basic key data according to the order of priority from high to low until the migration time length of the added N application data and the basic key data is greater than a preset time length threshold value, and takes the added first N-1 application data as recommended application data, wherein N is a positive integer.

The application recommendation calculation module can determine the priority of each application data in the data to be migrated according to the use condition of the user; the application recommendation calculation module sequentially adds the application data with high priority on the basis of the basic key data according to the order of the priorities of the application data from high to low, and judges whether migration time length corresponding to the basic key data and the added application data with high priority is greater than a preset time length threshold value after adding one application data with high priority each time. When the migration time length corresponding to the basic key data and the added high-priority application data is smaller than or equal to a preset time length threshold, the application recommendation calculation module continues to add additional application data according to the order of the priorities of the application data from high to low until the migration time length corresponding to the basic key data and all the added application data is larger than the preset time length threshold. And assuming that after N application data are added in turn, the migration time length corresponding to the N application data and the basic key data is longer than a preset time length threshold, and taking the added first N-1 application data as recommended application data. Therefore, the target migration duration required for migrating the target migration data (including the basic key data and the recommended application data) to the second electronic device is estimated to be less than or equal to the preset duration threshold.

For example, each application data in the data to be migrated is: the first application data X1, the second application data X2, the third application data X3, the fourth application data X4 and the fifth application data X5, and the application data in the data to be migrated sequentially comprises the following steps according to the order of priority from high to low: fifth application data X5, first application data X1, second application data X2, fourth application data X4, and third application data X3. Therefore, under the condition that the second migration time is smaller than the preset time threshold, the application recommendation calculation module adds fifth application data X5 on the basis of the basic key data, and judges whether migration time corresponding to the basic key data and the fifth application data X5 is larger than the preset time threshold.

When the migration time length corresponding to the basic key data and the fifth application data X5 is greater than a preset time length threshold, recommending that the application data is empty, and the target application data at the moment is the basic key data; and when the migration duration corresponding to the basic key data and the fifth application data X5 is less than or equal to the preset duration threshold, the application recommendation calculation module continues to add the first application data X1, and judges whether the migration duration corresponding to the basic key data, the fifth application data X5 and the first application data X1 is greater than the preset duration threshold. When the migration time length corresponding to the basic key data, the fifth application data X5 and the first application data X1 is longer than a preset time length threshold, the fifth application data X5 is used as recommended application data; and when the migration time length corresponding to the basic key data, the fifth application data X5 and the first application data X1 is less than or equal to the preset time length threshold, continuing to add the application data according to the mode until the migration time length of the added N application data and the basic key data is greater than the preset time length threshold, and taking the added first N-1 application data as recommended application data.

In some embodiments, when determining the priority of each application data in the data to be migrated, the application recommendation calculation module may set the usage situation of the application program corresponding to each application data.

Specifically, the first electronic device obtains use parameters of the application programs corresponding to each application data, wherein the use parameters comprise use duration and/or use frequency; and the first electronic equipment determines the priority of each application data in the data to be migrated according to the use parameters.

The application recommendation calculation module can call the android disclosure interface to obtain the use parameters of the application programs corresponding to each application data, wherein the use parameters comprise the use duration and/or the use frequency. Then, the application recommendation calculation module determines the priority of each application data in the data to be migrated according to the use parameters.

The use time length of the application program corresponding to each application data is positively correlated with the corresponding priority thereof, namely, when the use time length of the application program corresponding to the application data is longer, the priority corresponding to the application data is higher, and when the use time length of the application program corresponding to the application data is shorter, the priority corresponding to the application data is lower. The use frequency of the application programs corresponding to each application data is positively correlated with the corresponding priority thereof, namely, when the use frequency of the application programs corresponding to the application data is higher, the priority corresponding to the application data is higher, and when the use frequency of the application programs corresponding to the application data is lower, the priority corresponding to the application data is lower.

The acquired usage parameter of the application program may be a usage parameter of the application program within a preset period of time. The preset period may be a use parameter for a certain period of time before the current time, for example, the preset period may be a use parameter for 1 week, 2 weeks, 1 month, or the like before the current time.

It should be noted that, the above current time may be understood as a time when the application recommendation calculation module invokes the android disclosure interface to obtain the usage parameters.

In the first case, the usage parameters include only the usage duration. The application recommendation calculation module in the first electronic device can directly take the use time length of the application program corresponding to each application data as the priority of each application data.

That is, the application recommendation calculation module may sort the usage time periods of the application programs corresponding to the respective application data in a descending order, and the higher the priority of the application data before the sorting is, the lower the priority of the application data after the sorting is.

In the second case, the usage parameters include only the usage frequency. The application recommendation calculation module in the first electronic device can directly take the use frequency of the application program corresponding to each application data as the priority of each application data.

That is, the application recommendation calculation module may sort the usage frequency of the application programs corresponding to each application data in a descending order, and the higher the priority of the application data before the sorting is, the lower the priority of the application data after the sorting is.

In a third case, the usage parameters include a usage duration and a usage frequency. The application recommendation calculation module in the first electronic device can perform weighted summation on the use duration and the use frequency of the application program corresponding to each application data to obtain the priority of each application data. That is, the priority level y=w1×t+w2×p of the application data, W1 is the weight of the usage time period, T is the usage time period of the application program corresponding to the application data, W2 is the weight of the usage frequency, and P is the usage frequency of the application program corresponding to the application data.

That is, the application recommendation calculation module may sort the weighted summation results of the usage time periods and the usage frequencies corresponding to the respective application data in a descending order, where the higher the priority of the application data before sorting is, the lower the priority of the application data after sorting is.

The weight of the usage period and the weight of the usage frequency may be set according to an empirical value. The weights of the usage periods and the usage frequencies may be equal or unequal, which is not limited in the embodiment of the present application. For example, the weight of the usage period and the weight of the usage frequency may be both 0.5, or the weight of the usage period is 0.4, and the weight of the usage frequency is 0.6.

In step 412, the first electronic device uses the basic key data and the recommended application data as target migration data.

In some embodiments, the application recommendation calculation module in the cloned application takes the base key data and the recommended application data as target migration data after determining the recommended application data.

The target migration data at this time includes basic key data and recommended application data, and since the basic key data and recommended application data are part of key data in the data to be migrated, the target migration data can also be understood as part of data in the data to be migrated.

Therefore, in combination with the steps 407 to 412, it can be seen that in the embodiment of the present application, the second preset duration corresponding to the basic key data is compared with the preset duration threshold, and a portion of the key target migration data is determined from the data to be migrated, which is used as the data when the data migration is performed for the first time.

In other embodiments, the target migration data may also be determined directly according to a preset duration threshold. When the preset duration threshold is smaller than or equal to the first set threshold, the basic key data are used as target migration data, and when the preset duration threshold is larger than the first set threshold, the basic key data and the recommended application data with higher priority are used as target migration data. And, the larger the difference between the preset duration threshold and the first set threshold, the larger the amount of recommended application data. The first set threshold may be determined based on empirical values.

Alternatively, in some embodiments, the target migration data may also be determined directly according to the first migration duration of the data to be migrated. When the first migration time length is smaller than or equal to a second set threshold value, the basic key data are used as target migration data, and when the first migration time length is longer than the second set threshold value, the basic key data and recommended application data with higher priority are used as target migration data. And, the larger the difference between the first migration period and the second set threshold value, the larger the amount of recommended application data. The second set threshold may be determined based on empirical values.

In step 413, the first electronic device migrates the target migration data to the second electronic device.

In some embodiments, after determining the first migrated target migration data, the first electronic device may migrate the target migration data to the second electronic device, thereby implementing fast migration of the critical target migration data on the first electronic device to the second electronic device, so that the user may use the second electronic device in a short time.

In one possible implementation, after determining the target migration data for the first migration, the first electronic device displays a migration mode selection interface 901 as shown in (a) of fig. 9. The migration mode selection interface 901 includes a description related to a recommended data migration mode and a description related to a full-scale data migration mode provided in the embodiment of the present application, where the description related to the recommended data migration mode may be referred to as a first option.

The recommended data migration mode may also be referred to as a very simple mode, where the recommended data migration mode is used to migrate target migration data in the first electronic device to the second electronic device, where the target migration data is some basic data in the first electronic device, so that when the recommended data migration mode is used to perform data migration, the machine change speed is faster. In addition, the relevant description of the recommended data migration mode includes the data amount of the target migration data, as shown by "data size 10.54GB" in fig. 9 (a), and the relevant description of the recommended data migration mode further includes estimating the target migration period required to move the target migration data to the second electronic device, as shown by "estimated time-consuming 19 minutes" in fig. 9 (a). It can be seen that the target migration duration "19 minutes" is less than the preset duration threshold "20 minutes".

And the full-volume data migration mode is used for completely migrating all data to be migrated in the first electronic device to the second electronic device. In addition, the related description of the full-size data migration mode includes the data amount of all data to be migrated, as shown by "data size 32.59GB" in fig. 9 (a), and also includes a first migration period required to estimate migration of all data to be migrated to the second electronic device, as shown by "expected time period of 59 minutes" in fig. 9 (a).

In addition, the migration mode selection interface 901 further includes a first mode selection control 9011 corresponding to the recommended data migration mode, and a second mode selection control 9012 corresponding to the full-scale data migration mode. The first mode selection control 9011 is an "immediate migration" control corresponding to the recommended data migration mode shown in fig. 9 (a), and the second mode selection control 9012 is an "immediate migration" control corresponding to the full-volume data migration mode shown in fig. 9 (a).

When the user needs to implement quick change, the user may click on the first mode selection control 9011 in the migration mode selection interface 901, and the first electronic device displays the first data selection interface 902 as shown in (b) of fig. 9 in response to the first operation on the first mode selection control 9011. The first data selection interface 902 includes a data list of target migration data and a first migration control 9021, where the first migration control 9021 is a "next" control shown in (b) in fig. 9.

The data list of the target migration data includes application icons and selection boxes corresponding to the respective data in the target migration data. Taking the example that the target migration data includes basic key data and recommended application data, as shown in (b) of fig. 9, the data list of the target migration data may include a contact icon, an information icon (i.e., a text message icon), a call record icon, a document icon, a system setting icon, a memo icon, a schedule icon, and recommended application and data icons. The user can determine whether to migrate the data corresponding to the application icon when the data migration is performed for the first time by clicking the selection box corresponding to the application icon. In addition, the content such as the data size of the data is displayed at the position corresponding to the application icon corresponding to each data.

The user may click on a first migration control 9021 in the first data selection interface 902, and the first electronic device migrates the target migration data to the second electronic device in response to a second operation on the first migration control 9021.

Further, the first electronic device, in response to a second operation of the first migration control 9021, may first jump from the first data selection interface 902 to a data transfer interface 903 as shown in fig. 9 (c). The data transmission interface 903 may display related prompt information when migrating the target migration data of the first electronic device 100 to the second electronic device, such as information including an application name, a data transmission progress, a data transmission rate, and a time period required when the data transmission is completed, which correspond to the data currently being transmitted.

In addition, the data transfer interface 903 also includes a cancel control 9031. When the user needs to cancel the current data migration operation, the user may click on the cancel control 9031, and the first electronic device may cancel the operation of the current data migration in response to the click operation on the cancel control 9031.

In the case where the first electronic device migrates all of the target migration data to the second electronic device, the first electronic device may jump from the data transfer interface 903 to a data migration report interface 904 as shown in (d) in fig. 9. The data migration report interface 904 includes a prompt message, which is used to prompt that the migration of the target migration data is completed, and that the remaining data can be migrated when the next connection is performed, as shown in (d) of fig. 9.

Note that the interfaces shown in fig. 9 (a) to 9 (d) are only examples. In practical applications, the interface involved in the migration process of the first electronic device to migrate the target migration data to the second electronic device may further include other more or less contents, which is not limited by the embodiment of the present application.

As shown in fig. 9 (a), for the data to be migrated of 32.59GB, the expected migration duration is 59 minutes when all the data to be migrated is migrated to the second electronic device, so that the embodiment of the present application may determine a portion of critical target migration data from the data to be migrated, where the data amount of the target migration data is 10.54GB, and the expected duration is 19 minutes when the target migration data is migrated to the second electronic device. Therefore, the data migration time is reduced, and the user can quickly use the second electronic device in a short time.

Therefore, the embodiment of the application can determine the preset time length threshold for finishing the data migration through the data quantity of the data to be migrated in the first electronic device, determine the target migration data in the data to be migrated based on the preset time length threshold, and quickly migrate the target migration data on the first electronic device to the second electronic device, thereby reducing the time length required by migrating the target migration data to the second electronic device, and enabling a user to quickly use the second electronic device in a shorter time.

The data migration process shown above is directed to a scenario in which only target migration data is migrated for the first time, and since the data to be migrated in the first electronic device includes other non-migration data in addition to the target migration data. Therefore, in practical application, when the user is in urgent use of the second electronic device, the target migration data may be migrated to the second electronic device, and then other non-migration data except the target migration data is migrated slowly when the waiting time is abundant.

Fig. 10 is a flowchart of a first electronic device migrating non-migrated data to a second electronic device according to an embodiment of the present application. Referring to fig. 10, the data migration method may specifically include the following steps:

in step 1001, the first electronic device migrates the target migration data to the second electronic device.

For the specific execution process of first migrating the target migration data to the second electronic device, reference may be made to the specific execution process of the embodiment shown in fig. 4, and in order to avoid repetition, a description thereof will be omitted.

In step 1002, the first electronic device is disconnected from the second electronic device in the case where the target migration data is completely migrated to the second electronic device.

In some embodiments, where the first electronic device migrates all of the target migration data to the second electronic device, the first electronic device will display a data migration report interface 904 as shown in fig. 9 (d). The data migration report interface 904 includes a prompt message, which is used to prompt that the migration of the target migration data is completed, and the remaining data can be migrated when the data is connected next time. In addition, the data migration report interface 904 also includes a validation control 9041, which validation control 9041 may be a "know" control as shown in fig. 9 (d).

The user can perform clicking operation on the confirmation control 9041 in the data migration report interface 904, and the first electronic device responds to clicking operation on the confirmation control 9041 by the user and controls the first electronic device to disconnect from the second electronic device, so that the user can normally use the second electronic device.

In step 1003, the first electronic device reestablishes the connection with the second electronic device.

In some embodiments, the first electronic device reestablishes a connection with the second electronic device when the user wants to migrate data that was not migrated last time by the first electronic device to the second electronic device during the idle period. The manner in which the first electronic device reestablishes the connection with the second electronic device may be referred to the description corresponding to step 401 above.

In step 1004, the first electronic device receives the first session ID sent by the second electronic device.

In some embodiments, in the process that the first electronic device establishes a connection with the second electronic device for the first time and migrates the target migration data to the second electronic device, the first electronic device may randomly generate a first session ID, and the first electronic device and the second electronic device may respectively store the first session ID. Wherein the first session ID may be a universally unique identifier (universally unique identifier, UUID).

Thus, after the first electronic device establishes a connection with the second electronic device again, the second electronic device may send the first session ID stored therein to the first electronic device.

In an alternative implementation manner, after the first electronic device establishes connection with the second electronic device again, the first electronic device sends a session ID query request to the second electronic device, and the second electronic device returns the saved first session ID to the first electronic device according to the session ID query request.

In another alternative implementation, after the first electronic device establishes the connection with the second electronic device again, the second electronic device directly sends the first session ID stored in the second electronic device to the first electronic device, without the first electronic device having to obtain the first session ID by sending a session ID query request.

In step 1005, the first electronic device determines whether a session ID consistent with the first session ID is stored.

In some embodiments, the first electronic device, after receiving the first session ID sent by the second electronic device, queries whether it has previously stored a session ID, and whether the stored session ID is consistent with the first session ID sent by the second electronic device.

When the session ID stored in the first electronic device is consistent with the first session ID sent by the second electronic device, it indicates that the connection has been established between the first electronic device and the second electronic device, that is, the connection is not the first connection, in this case, the following step 1006 is executed.

When the first electronic device does not store the session ID, or the stored session ID is inconsistent with the first session ID sent by the second electronic device, it is indicated that the first electronic device and the second electronic device have not been previously connected, that is, the connection is the first connection, in this case, the steps corresponding to the first migration operation may be executed according to the embodiment shown in fig. 4, which is not described herein again.

In step 1006, if the first electronic device stores a session ID consistent with the first session ID, the first electronic device displays a prompt box to prompt the user whether to continue to migrate the last data that has not been migrated.

In the case where the first electronic device stores a session ID that matches the first session ID, the first electronic device pops up a prompt 1101 on the sixth clone interface 603, at which point the interface displayed on the first electronic device is as shown in fig. 11. The prompt box 1101 includes prompt information for prompting the user whether to continue to migrate the last data that has not been migrated, such as "whether to continue to migrate the last data that has not been migrated" in the prompt box 1101 shown in fig. 11; the prompt box 1101 further includes a data list of non-migrated data, where the data list of non-migrated data includes application icons and selection boxes corresponding to respective data in the non-migrated data, and as shown in fig. 11, the data list of non-migrated data may include gallery icons, music icons, applications, data icons, and the like. At a position corresponding to the application icon corresponding to each data, contents such as a data size of the data are also displayed.

In addition, prompt 1101 includes a confirm control and a cancel control. When the user does not need to migrate the last data which is not migrated, and the user clicks the cancel control in the prompt box 1101, the first electronic device responds to the click operation of the cancel control in the prompt box 1101 to withdraw from the migration operation of the data which is not migrated.

In step 1007, the first electronic device receives a third operation of the confirmation control in the prompt box by the user.

In step 1008, the first electronic device migrates the non-migrated data to the second electronic device in response to the third operation.

In some embodiments, when the user needs to migrate the last data that has not been migrated to the second electronic device, the user may click on the confirmation control in the prompt 1101, so that the first electronic device receives a third operation of the confirmation control in the prompt 1101 by the user, where the third operation may be understood as a click operation on the confirmation control in the prompt 1101.

And the first electronic device responds to the third operation of the confirmation control to migrate the non-migrated data to the second electronic device, wherein the non-migrated data is the data except the target migration data in the data to be migrated.

The determination method of the non-migrated data can be determined in the following two ways. In the first manner, after the first electronic device sends the target migration data to the second electronic device, the first electronic device records the migrated target migration data, so that the first electronic device directly determines other non-migrated data except the target migration data in the data to be migrated according to the recorded target migration data. In the second mode, after the first electronic device and the second electronic device establish connection again, the second electronic device reads the target migration data received before and then sends the data list of the target migration data to the first electronic device, so that an electronic device can determine other non-migrated data except the target migration data in the data to be migrated according to the data list of the target migration data sent by the second electronic device.

The data migration process shown above is directed to a scenario of migrating only target migration data for the first time, and in the embodiment of the present application, the first electronic device may migrate all data to be migrated to the second electronic device when establishing connection with the second electronic device for the first time.

The migration mode selection interface 901 shown in fig. 12 (a) is the same as the migration mode selection interface 901 shown in fig. 9 (a), and includes a description of the full-size data migration mode and a second mode selection control 9012 corresponding to the full-size data migration mode.

When the user needs to migrate all the data to be migrated together to the second electronic device, the user may click on the second mode selection control 9012 in the migration mode selection interface 901, and the first electronic device displays the second data selection interface 1200 as shown in (b) of fig. 12 in response to the click operation on the second mode selection control 9012. The second data selection interface 1200 includes a data list of all data to be migrated, where the data list of the data to be migrated includes application icons and selection boxes corresponding to each data in all data to be migrated.

Note that, the interface shown in (c) in fig. 12 is also the second data selection interface 1200, and since there may be a problem of incomplete display when the display screen of the first electronic device displays the entire data list of the data to be migrated, the second data selection interface 1200 shown in (c) in fig. 12 may be displayed by sliding upward in the arrow direction shown in (b) in fig. 12.

In addition, the second data selection interface 1200 also includes a second migration control 1201, and the first migration control 9021 is a "next" control shown in (c) in fig. 12.

The user may click on the second migration control 1201 in the second data selection interface 1200, and the first electronic device migrates all the data to be migrated to the second electronic device in response to the click operation on the second migration control 1201.

In summary, the data migration method of the embodiment of the application not only supports the data migration of the extremely simple mode to reduce the time required by the data migration, but also supports the data migration of the full-quantity mode, so that a user can select a proper migration mode according to actual conditions, thereby improving the use experience of the user.
