Detailed Description

In order to enable those skilled in the art to better understand the embodiments of the present application, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

Message queue (Message queue): is a communication mode between processes or between different threads of the same process. The message queue can be used as a container for storing the message in the transmission process, and a process with writing permission on the message queue can add new message into the message queue; a process having read rights to the message queue may then read the message from the message queue. Where the message queue has a first-in first-out principle, i.e. the message that first enters the message queue is read (or sent) first.

The process comprises the following steps: is the basic unit of resource allocation and scheduling by an operating system (such as an android system) regarding one running activity of an application program on a certain data set. Each process occupies an address space, and an application program runs on an operating system in the form of one or more processes to realize corresponding functions.

Thread: is an entity of a process that is a smaller, independently operable basic unit than the process. A thread may share all of the resources owned by a process with other threads that belong to the same process. One thread may create and cancel another thread and multiple threads in the same process may execute concurrently.

Fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present application. As shown in connection with fig. 1, the scenario includes a first electronic device and a second electronic device; the first electronic device may be, for example, a new device, and the second electronic device may be, for example, an old device. The old device and the new device may be communicatively coupled via a wireless or wired connection. The wired communication connection may be, for example, a universal serial bus (universal serial bus, USB) connection; the wireless connection may be, for example, a wireless fidelity (wireless fidelity, wi-Fi) connection, a bluetooth (bluetooth) connection, a bluetooth mesh connection, a peer-to-peer (P2P) connection, etc. Fig. 1 illustrates an example of a notebook computer as a first electronic device and a second electronic device.

Generally, in order to improve the use experience of a user, the electronic device may respond to the operation of the user to select to migrate all or part of the data stored on the old device to the new device, so as to facilitate the user to continue to use daily important applications, files and the like on the new device. The data stored on the old device may include, for example: video, pictures, documents, APP, and other device configuration. In the related art, when data of the same name is stored on both the new device and the old device, after the old device migrates the data onto the new device, the new device stores the data and updates the name of the data to the duplicate name. However, if the content of the data with the same name stored on the new device is the same as that of the old device, the old device will cause the new device to store the data with the same content when migrating the data to the new device, thereby occupying the storage space of the new device.

Illustratively, the new device has stored thereon data named xxx.t.txt, and the old device has stored thereon data named xxx.t.txt; it can be seen that the data stored on the new device is the same name as the data stored on the old device. Then, when the old device migrates data named xxx.t.txt onto the new device, the new device stores the data and updates the name of the data to xxx.t.txt (1). Thus, the new device has stored thereon data named xxx.t.txt and data named xxx.t.txt (1); however, in the case where the content of the data named xxx.t.txt and the content of the data named xxx.t.txt (1) are the same, this results in that the new device stores the same content of data, and thus occupies the storage space of the new device.

The embodiment of the application provides a data migration method, which can solve the problem that the storage space of new equipment is occupied when data with the same content are stored on the new equipment. Specifically, after the old device sends a plurality of migration data to the new device, the new device may detect whether the data on the new device with the same name is the same as the content of the migration data; if so, the new device stores one of the two data with the same name, which is beneficial to reducing the storage space of the new device.

The data migration method provided by the embodiment of the application can be applied to the communication system described in fig. 1.

It is to be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device may include more or less components than illustrated, or certain components may be combined, or certain components may be split, or different arrangements of components. The illustrated components may be implemented in hardware, software, or a combination of hardware and software.

The following describes a specific implementation procedure of the data migration method provided in the embodiment of the present application with reference to the accompanying drawings.

In the embodiment of the application, the old device and the new device can perform data migration through a data migration application or an application with a data migration function. It should be appreciated that prior to the old device and the new device performing data migration, the old device and the new device first establish a communication connection, and then the old device and the new device initiate a data migration function to perform data migration.

Taking the old device and the new device with data migration applications installed thereon as an example for illustration, in some embodiments, the old device and the new device automatically launch the data migration applications to launch the data migration functions when the old device and the new device are powered on. In other embodiments, the home page of the computer manager application of the old device and the new device includes a data migration setting item, and the old device and the new device may initiate a data migration function in response to a user operating the data migration setting item. In still other embodiments, a data migration application is installed on desktops of the old device and the new device, and the old device and the new device may initiate data migration functions in response to user operations on the data migration application.

Taking the example where the home page of the computer manager application of the old device and the new device includes a data migration setting item as an illustration, the old device and the new device display an interface 201 as shown in (1) of fig. 3 in response to a user's operation of the data migration setting item, the interface 201 including a start control. Wherein the launch control may be, for example, "immediate migration". The old device and the new device then display an interface 202 as shown in fig. 3 (2) in response to the user's operation of the launch control, the interface 202 including first prompting information for prompting the user for data migration user protocols. For example, the first prompt information may be: the service needs to turn on WLAN and Bluetooth, and occupies WLAN channels in the migration process, so that the network cannot be accessed temporarily, the service can automatically recover after the migration is completed, and 'consent' is clicked, namely, consent to the content and data migration user protocol is indicated.

Still as with interface 202 shown in fig. 3 (2), in some embodiments, the interface 202 further includes an consent control and a cancel control, the old device and the new device opening a data migration function in response to a user operation of the consent control; the old device and the new device exit the data migration in response to a user operation to cancel the control.

When the old device and the new device respond to the user's operation of the consent control, the old device and the new device display an interface 203 as shown in (3) of fig. 3, the interface 203 including a first icon and a second icon; wherein the first icon is used to indicate a new device and the second icon is used to indicate an old device. Illustratively, the old device responds to the operation of the user on the second icon, and selects the old device as the local device to serve as a data sender; and the new device responds to the operation of the user on the first icon, and selects the local device as the new device to serve as a data receiving party.

Also shown as interface 203 in fig. 3 (3), in some embodiments, the interface 203 further includes a second hint information that is used to hint the installation path of the data migration application to the user. The second prompt information may be, for example: please go to official website: http:// www.xxx.com downloads the install data migration application. In some embodiments, interface 203 further includes an exit control, which the old device and the new device exit data migration functionality in response to user operation of the exit control.

In some embodiments, the old device displays an interface 204 as shown in fig. 4 (1) in response to a user operation of the second icon; the interface 204 is the interface where the old device waits to be discovered. Illustratively, the old device sends a broadcast to the new device, and the "old device" in the display interface 204 is waiting for a reminder to be found. In some embodiments, interface 204 also includes a third hint information that is used to hint to the user to launch the data migration application on the new device. The third prompt information may be, for example: a data migration application is launched on the new device, selecting "this is the new device". If the new device does not install the data migration application, please go to the official website: http:// www.xxx.com downloads the install data migration application. In some embodiments, interface 204 also includes a prompt for "WLAN channel is occupied during migration, device cannot use network". In other embodiments, interface 204 also includes a "cancel" control; on this basis, the old device exits the data migration in response to a user operation of the "cancel" control.

In other embodiments, the new device displays an interface 205 as shown in fig. 4 (2) in response to a user operation of the first icon; the interface 205 is the interface where the new device is looking for the old device. Illustratively, the new device receives the broadcast sent by the old device and displays a prompt in interface 205 that device … is being looked up. In some embodiments, interface 205 also includes fourth hints information for prompting the user to launch a data migration application on the old device. The fourth prompt information may be, for example: a data migration application is launched on the old device, selecting "this is the old device". If the old device does not install the data migration application, please go to the official website: http:// www.xxx.com downloads the install data migration application. In some embodiments, interface 205 also includes a "continue" control and a "cancel" control. It should be noted that when the new device does not find the old device, the "continue" control is not clickable. If the user clicks the cancel control, the new device responds to the operation of the cancel control by the user, and the new device exits from data migration.

In some embodiments, after the new device finds the old device, the new device responds to the user's operation of the "continue" control in interface 205, the old device and the new device display a connection authentication interface, and if the connection authentication passes, the old device and the new device establish a communication connection. On this basis, the old device and the new device can perform data migration.

Illustratively, the old device and the new device may perform connection authentication by checking the connection code. For example, in response to operation of the "continue" control in user interface 205, the new device displays interface 206 as shown in FIG. 5 (1), which interface 206 includes a connection check code. The connection check code may be, for example, "078913". In some embodiments, interface 206 also includes a prompt such as "please see if the following connection code is displayed on the old device". In other embodiments, the interface 206 also includes a "cancel" control, e.g., the new device exits the data migration in response to a user's operation of the "cancel" control.

Accordingly, the old device displays an interface 207 as shown in fig. 5 (2), the interface 207 including a connection check code. The connection check code may be, for example, "078913". In some embodiments, interface 207 also includes a prompt such as "find that a new device is requesting a connection to the local, please confirm whether the following connections are consistent. In other embodiments, interface 207 also includes a "continue" control and a "cancel" control; under the condition that the connection check code on the old equipment is consistent with the connection check code on the new equipment, if the old equipment responds to the operation of the 'continue' control by the user, the old equipment and the new equipment are in communication connection; if the old device responds to the user operation of the "cancel" control, the old device exits the data migration.

Illustratively, in response to a user's operation of the "continue" control, the old device and the new device display an interface 208 as shown in FIG. 6, the interface 208 being the interface to which the old device and the new device are being connected. For example, as shown in FIG. 6, the interface 208 may include, for example, a prompt for "in connection" and a "cancel" control. In some embodiments, the old or new device exits the data migration in response to a user operation of a "cancel" control.

In connection with the above-described embodiments and the interfaces shown in fig. 3-6, data migration between the old device and the new device may begin after the old device and the new device establish a communication connection. The process of data migration between the old device and the new device may be implemented, for example, in conjunction with the flow diagram shown in fig. 7 and the method described in the embodiments below. Specifically, as shown in fig. 7, the process of the data migration method may include S301 to S306.

S301, the old device sends migration information I to the new device.

The first migration information comprises a first data identifier of each migration data in N migration data and a storage path of each migration data on old equipment; n is a positive integer. In the embodiment of the present application, the first migration information may also be referred to as second migration information. In addition, the storage path of migration data on the old device may also be referred to as a source path.

The first data identifier refers to a unique identifier code capable of characterizing the migration data. The first data identification may be, for example, a file name of the migration data.

Taking the file name of the first data identifier as migration data as an example, assuming that N migration data includes data a, data b, and data c, migration information one of the old device sends to the new device may be shown in table 1 below, for example.

Migrating data	Data identification	Source Path
			Data a	xxx-a	D\\AAA\t.txt
Data b	xxx-b	E:\\BBB\t.txt
			Data c	xxx-c	C:\\AAA\t.txt

TABLE 1

In some embodiments, during the process of the old device sending migration information one to the new device, the old device displays an interface 209 as shown in FIG. 8, the interface 209 including a progress bar for the old device to send migration information one to the new device, and a "cancel" control. Meanwhile, a prompt interface for successful connection is displayed on a display screen of the new equipment. The progress bar is used for prompting a user of the progress of the old equipment for sending migration information I to the new equipment.

In some embodiments, the old device exits the data migration in response to a user operation of a "cancel" control.

S302, the new device determines a target storage path of each migration data in the M migration data according to a preset storage rule according to the first migration information.

The preset storage rule is used for indicating the corresponding relation between the storage path of the migration data on the old equipment and the storage path of the corresponding migration data to be stored on the new equipment. M is a positive integer, M is less than or equal to N.

In some embodiments, after the new device receives the migration information one sent by the old device, the new device displays the first interface. The first interface is used for selecting one or more migration data from N migration data to obtain M migration data; and then, the new device determines a target storage path of each migration data in the M migration data according to a preset disk storage rule.

Illustratively, as shown in FIG. 9, after the new device receives migration information one sent by the old device, the new device displays an interface 210 (i.e., a first interface); the interface 210 includes the name of the storage partition of the old device and a first data identification (e.g., file name) of the N pieces of migration data stored under the storage partition of the old device. In some embodiments, interface 210 also includes hints for the storage space size of the new device, hints for the file size of the selected migration data, hints for the number of selected migration data, hints for the expected migration duration, and the like. In some embodiments, interface 210 also includes a "begin migration" control and a "cancel" control.

For example, as shown in FIG. 9, interface 210 includes a "local disk C" selection and a "local disk D" selection; wherein, the selection items of the local disk D comprise a My file selection item and a My Drive selection item; the My File sub-selections include "index" and "image" files. For example, the new device responds to the user selection operation of the selection item "local disk C" in the interface 210, and all migration data stored in "local disk C" is selected. Accordingly, the new device may also select M pieces of migration data from the N pieces of migration data in response to a user selection operation of other options in the interface 210.

It should be noted that, when the new device responds to the selection operation of all the options in the interface 210 by the user, the M pieces of migration data selected by the new device are all the data on the old device, i.e., n=m. When the new device responds to the selection operation of the partial selection item in the interface 210 by the user, the M migration data selected by the new device are the partial data on the old device, i.e. M < N.

In some embodiments, assuming that the M migration data includes data a, data b, and data c, the preset inventory rules may be as shown in table 2 below, for example.

Migrating data	Data identification	Source Path	Target storage path
				Data a	xxx-a	D\\AAA\t.txt	C:\\AAA\t.txt
Data b	xxx-b	E:\\BBB\t.txt	E:\\BBB\t.txt
				Data c	xxx-c	C:\\AAA\t.txt	D:\\AAA\t.txt

TABLE 2

Illustratively, as shown in table 2, the new device searches the target storage path of the corresponding migration data in the preset storage rule according to the first data identifier and the source path of each of the M migration data. For example, the data mark of the data a is xxx-a, the source path is D\AAA\t.txt, and then the new device determines that the target storage path of the data a is C\AAA\t txt according to the preset storage rule. Accordingly, the new device may also search the preset storage rule for the target storage path of other data, which is not described herein.

And S303, the new equipment sends migration information II to the old equipment.

The migration information II comprises: the first data identification of each of the M pieces of migration data, and the first data identification indicates a target storage path of the migration data. In the embodiment of the present application, the second migration information may also be referred to as first migration information.

The migration information two sent by the new device to the old device may be shown in table 3 below, for example.

Migrating data	Data identification	Target storage path
			Data a	xxx-a	C:\\AAA\t.txt
Data b	xxx-b	E:\\BBB\t.txt
			Data c	xxx-c	D:\\AAA\t.txt

TABLE 3 Table 3

S304, the old equipment sends M pieces of migration data to the new equipment according to the migration information.

Accordingly, the new device receives M pieces of migration data sent by the old device according to the migration information II.

Illustratively, in the process of the old device sending M pieces of migration data to the new device, the old device and the new device display an interface 211 as shown in FIG. 10; the interface 211 includes prompt information for prompting the user for data migration progress. For example, interface 211 includes migration progress (e.g.,%), size of migrated data, migration rate, and remaining time, etc.

S305, the new device judges whether target data is included in the target storage path of the first migration data in the M migration data.

Wherein the second data identification of the target data is the same as the first data identification of the first migration data. That is, after receiving the M pieces of migration data, the new device determines whether the data identical to the first data identification of the first migration data is included in the target storage path of the first migration data.

In some embodiments, if the target data is included in the target storage path of the first migration data, the new device performs S306; and if the target storage path of the first migration data does not comprise the target data, the new device stores the first migration data in the target storage path of the first migration data.

It should be appreciated that the first migration data is any one of the M migration data. In the embodiment of the application, for each migration data in M migration data, the new device determines whether the target data is included in the target storage path of each migration data; if so, the new device executes S306.

S306, the new device judges whether the contents of the target data and the first migration data are the same.

In some embodiments, the new device stores one of the target data or the first migration data if the target data is the same as the first migration data. Illustratively, the new device stores the first migration data under the target storage path of the first migration data and deletes the target data; or the new device does not store the first migration data under the target storage path of the first migration data, and the target data is reserved.

In other embodiments, if the target data is different from the first migration data, the new device stores the first migration data under the target storage path of the first migration data and retains the target data.

Illustratively, the new device may determine whether the target data and the first migration data are the same content by comparing the sha256 (i.e., hash value) of the target data with the sha256 of the first migration data.

It should be noted that sha256 is an algorithm subdivided under sha-2 (secure hash algorithm 2). Wherein sha-2 is a cryptographic hash function algorithm. In some embodiments, the input to sha256 is a message of arbitrary length and the output of sha256 is a256 bit hash value.

In summary, in the embodiment of the present application, when the new device receives the M pieces of migration data sent by the old device, and when the target data is included in the target storage path of the first migration data in the M pieces of migration data, the second data identifier of the target data is the same as the first data identifier of the first migration data, so that the new device determines that the target data having the same name as the first data of the first migration data is included in the target storage path of the first migration data; on the basis, the new device detects whether the contents of the target data and the first migration data are the same, if the contents of the target data and the first migration data are the same, the new device stores one of the target data or the first migration data, namely, the target data and the first migration data are the same, and the new device stores only one of the target data and the first migration data, so that the problem that the storage space of the new device is occupied due to the fact that the data with the same contents are stored on the new device in the related art is solved.

Considering that the new device calculates that the sha256 of the target data and the sha256 of the first migration data are time-consuming, after receiving the M migration data sent by the old device, the new device first stores the first migration data in a target storage path corresponding to the first migration data, and then the new device judges whether the content of the target data is the same as that of the first migration data. In this way, the new device calculates the sha256 of the target data and the sha256 of the first migration data, so that the storage speed of the first migration data is not affected, and the efficiency of data migration is improved.

In some embodiments, as shown in fig. 11, before the new device detects whether the target data and the first migration data are identical in content, the method further includes:

and S3051, the new device stores the first migration data under the target storage path of the first migration data, and updates the first data identification of the first migration data into the third data identification.

Taking the first data identification as a file name as an example, illustratively, after the new device stores the first migration data, the file name of the first migration data is modified to be a copy name. For example, the first data identification of the first migration data is xxx-a, and then the third data identification of the first migration data may be xxx-a (1), for example.

On the basis, if the new device detects that the content of the target data is the same as that of the first migration data, the new device can delete the first migration data corresponding to the third data identifier, namely the new device deletes the first migration data of the new storage disk, and the target data is reserved.

As shown in connection with fig. 11, in some embodiments, where target data is included in the target storage path of the first migration data, the new device may add the second data identifier and the third data identifier as a set of messages to the data queue to be migrated; on the basis, the new device detects whether the content of the target data corresponding to the second identifier and the content of the first migration data corresponding to the third identifier in a group of messages of the data queue to be migrated are the same according to the first-in first-out principle.

It should be noted that, the explanation of the data queue to be migrated may refer to the explanation of the message queue in the above embodiment, which is not described herein.

For example, it is assumed that among the M pieces of migration data, the target data a1 is included in the target storage path of the data a, the target data b1 is included in the target storage path of the data b, and the target data c1 is included in the target storage path of the data c. On this basis, as shown in fig. 12, the new device adds the second data identifier corresponding to the target data a1 and the third data identifier corresponding to the data a as a group of data into the data queue to be migrated; adding a second data identifier corresponding to the target data b1 and a third data identifier corresponding to the data b into a data queue to be migrated as a group of data; and the second data identifier corresponding to the target data c1 and the third data identifier corresponding to the data c are used as a group of data to be added into a data queue to be migrated.

Thus, the data queue to be migrated includes three sets of messages, each set of messages corresponding to a second data identifier and a third data identifier. It should be appreciated that each time the new device determines that the target data is included in the target storage path of the migrated data, a set of messages is added to the queue of data to be migrated.

It should be noted that the data queue to be migrated has a first-in first-out principle, i.e. data that enters the queue first-out. In this embodiment of the present application, first, the second data identifier and the third data identifier in the data queue to be migrated first, and then the new device will first detect whether the content of the first migration data corresponding to the second data identifier and the content of the target data corresponding to the third data identifier are the same.

In this embodiment, under the condition that the target data is included in the target storage path of the first migration data, since the new device adds the second data identifier and the third data identifier as a group of messages into the data queue to be migrated, and the data queue to be migrated has the first-in first-out principle, that is, the second data identifier and the third data identifier enter the queue first, the new device will detect whether the content of the first migration data corresponding to the second identifier and the content of the first migration data corresponding to the third data identifier are the same first, so that the storage speed of the first migration data is not affected, and the data migration efficiency is further improved.

In some embodiments, as shown in connection with fig. 12, the new device sequentially detects whether the contents of the target data and the first migration data corresponding to each group of messages in the data queue to be migrated are the same. For each group of messages in the data queue to be migrated, the new device inputs a second data identifier in a group of messages into a preset algorithm model and outputs a first message identifier; inputting a third data identifier in a group of messages into a preset algorithm model, and outputting a second message identifier; when the first message identifier is the same as the second message identifier, the new device determines that the contents of the target data and the first migration data are the same; when the first message identifier and the second message identifier are different, the new device determines that the contents of the target data and the first migration data are different.

The first packet identifier and the second packet identifier may be, for example, 256-bit hash values.

When the first message identifier is the same as the second message identifier, the new device deletes the first migration data of the new storage disc, that is, the new device deletes the first migration data corresponding to the third data identifier, and the target data is reserved. When the first message identifier is different from the second message identifier, the new device reselects a group of messages from the data queue to be migrated, and detects whether the contents of the target data of the second data identifier corresponding to the group of messages and the first migration data of the third data identifier are the same.

In some embodiments, in conjunction with fig. 12, the new device may run multiple threads that detect in parallel whether the contents of the target data corresponding to the second data identifier and the first migration data corresponding to the third data identifier in a set of messages of the data queue to be migrated are the same, respectively.

Illustratively, as shown in FIG. 13, the new device runs with thread A, thread B, and thread C; the method comprises the steps that a new device running thread A detects whether target data corresponding to a second data identifier and first migration data corresponding to a third data identifier in a group of messages of a data queue to be migrated are the same in content or not; meanwhile, the new equipment operating thread B detects whether the content of the target data corresponding to the second data identifier and the content of the first migration data corresponding to the third data identifier in a group of messages of the data queue to be migrated are the same or not; meanwhile, the new device running thread C detects whether the content of the target data corresponding to the second data identifier and the content of the first migration data corresponding to the third data identifier in a group of messages of the data queue to be migrated are the same.

In this way, the new device runs a plurality of threads to detect whether the content of the target data corresponding to the second data identifier and the content of the first migration data corresponding to the third data identifier in a group of messages of the data queue to be migrated are the same in parallel, so that the time for the new device to detect the content of the target data and the content of the first migration data is reduced, and the power consumption of the device is reduced.

In some embodiments, when the old device sends M pieces of migration data to the new device, if the new device detects that the content of the target data is different from that of the first migration data, the new device sends out first prompt information; the first prompt information is used for prompting a user that the data identifier of the first migration data is updated from the first data identifier to the third data identifier.

Taking the first data identifier of the first migration data as xxx-a and the third data identifier of the first migration data as xxx-a (1) as an example for illustration, the first prompt information may be voice prompt information or text prompt information.

When the first prompt information is voice prompt information, the new device can play the voice message through the loudspeaker, and prompt the user that the data identification of the first migration data is updated from the first data identification to the third data identification. The voice prompt message may be, for example, "the name of the first migration data is updated from xxx-a to xxx-a (1)".

When the first prompt is a text prompt, as shown in fig. 14, the new device displays an interface 212, and the interface 212 includes the text prompt. The text prompt may be, for example, "the name of the first migration data is updated from xxx-a to xxx-a (1)".

In this embodiment, when the content of the target data is different from that of the first migration data, the new device may send the first prompt message, and since the data identifier of the first migration data used for prompting the user by the first prompt message is updated to the third data identifier by the first data identifier, that is, the new device may prompt the user through the prompt message which migration data is renamed, it is convenient for the user to find the migration data in the new device, and user experience is improved.
