For example, the data synchronization method provided in the embodiment of the present application is illustrated below, where the first electronic device is exemplified by the terminal a, the second electronic device is exemplified by the terminal B, the network hotspot device is exemplified by a router, and the second networking mode is exemplified by wifi p2p (wireless network direct connection).

In view of the foregoing technical problems, an embodiment of the present application provides a data synchronization method, which can be specifically implemented as a method for accelerating data synchronization by using a local area network, where the method includes: by using the centralized cloud service, the terminal a (such as a computer) synchronizes the file directory and the basic information (corresponding to the data information and having a small data amount) of the user through the internet, and then, according to the basic information of the file, the target terminal (i.e. the terminal B, such as a mobile phone) directly downloads the corresponding file content (corresponding to the synchronized data) through the local area network connection, so that the data synchronization speed can be greatly accelerated.

In addition, in the application, different networking schemes can be provided for different networking modes (the networking mode of the local area network comprises the first networking mode and the second networking mode). Specifically, the method can comprise the following steps: the networking mode (corresponding to the first networking mode) connected through the router and the point-to-point networking mode (corresponding to the second networking mode) connected through the wifi p2p (wireless network direct connection) are adapted to different user use scenes.

The following specifically exemplifies the scheme provided in the embodiments of the present application.

Example one (corresponding to the first networking approach described above):

assume that both terminal a (computer) and terminal B (mobile phone) have logged in the same data account (data account for synchronization), and as shown in fig. 3, both have connected to the same router or hotspot, and the router or hotspot has access to the internet. A cloud server exists to provide centralized synchronization services for multiple device terminals.

Based on the above, the overall scheme is mainly divided into three parts: part 1, establishing local area network connection (connection through a router); part 2, uploading data by a terminal B (mobile phone); part 3, terminal a (computer) downloads data.

Section 1 relates primarily to the following:

judging whether a local area network connection is established between a terminal A (computer) and a terminal B (mobile phone) for the first time, if so, entering the following operation 1, and if not, entering the following operation 2;

operation 1, local area network connection is established between a terminal A (computer) and a terminal B (mobile phone) for the first time.

In the scheme, the connection can be established by using an SSDP (simple service discovery protocol) local area network discovery mode. The terminal a and the terminal B may continuously send UDP (user datagram protocol) multicast messages to the multicast address in the local area network (for timely detection), and the messages may include device information of their own devices (which may be used for device list display), account information (which may be used for determining whether to log in the same account), an IP address (which may be used for subsequent connection between the terminal a and the terminal B), and the like. After receiving the message, the opposite terminal displays the devices found in the lan to a connectable device list, as shown in fig. 4. The devices that log in the same account are filtered out from the device list. The user clicks on the device in the device list, and a local area network connection can be established with the device.

After the local area network connection is established successfully for the first time, the ID of the equipment which is successfully connected for the last time can be recorded in the database.

And 2, establishing local area network connection between the terminal A (computer) and the terminal B (mobile phone) for the non-first time.

If the 'subsequent automatic connection' is selected during the first connection, after the terminal A (computer) and the terminal B (mobile phone) access the same router, the local area network discovery can be performed according to the mode in the operation 1 of the part. After finding the device list and before showing the device list, the terminal a may obtain the ID of the opposite device successfully connected for the last time from the database, and query the ID from the device list. If the device ID exists in the device list, the direct connection is successful. Otherwise, displaying the device list.

Section 2 relates primarily to the following:

operation 1, terminal B (mobile phone) triggers synchronization, uploads data information (corresponding to the text type data) and performs file pre-upload (corresponding to the data information).

Specifically, the terminal B (mobile phone) generates user data after the user performs actions such as note editing, photographing, document editing, picture and/or video receiving, and the like. The user data is divided into two types:

(1) Text type data: the data volume is small, and the transmission is fast. Such as notes, schedules, contacts, album directory structures, etc.

(2) File type data: the data volume is large and the transmission is slow. Such as a photo, video, etc. file type.

As shown in fig. 5, after data is generated, data synchronization (including dividing data into the above two types for uploading) is triggered once. Judging whether the terminal (namely the terminal B) is accessed to the Internet or not, and if so, uploading text type data to a server (corresponding to the cloud server); after the text type (data) is uploaded, the file of each file type data needs to be pre-uploaded, and the pre-uploading is used for uploading a small amount of summary information (corresponding to the data information) of the file in advance, so that other terminals can display icons and basic information (such as file size, file name, final modification time and the like) of the file on an interface under the condition that the specific content of the file is not uploaded or downloaded. The pre-upload content may include file summary information (corresponding to the above data information) such as a file name, a file size, a file type, a thumbnail, and the like, but does not include specific file content. Dividing the data to be synchronized into text type data and file type data correspondingly; according to the file type data, determining synchronous data and data information of the synchronous data; and uploading the data information of the text type data and the synchronous data to a cloud server.

The server analyzes the file summary information when the files are pre-uploaded, generates a GUID (globally unique identifier corresponding to the data identifier) for each file, and returns the GUID to the client terminal B (mobile phone). The GUID is a unique identifier of each file in the cloud server, and the GUID can be used for locating a certain file under a certain user (account number), and is used for binding the summary information pre-uploaded by the file with a file body and locating the file.

After receiving the GUID generated by the server, the terminal B (mobile phone) associates the GUID with the local file path (corresponding to the local storage path), and records the GUID in the database (local to the terminal B). At this point, the file pre-upload is complete. Receiving a data identifier sent by the cloud server according to the data information; and associating the data identification with a local storage path of the synchronous data, and storing.

Operation 2, the terminal B (mobile phone) judges a local environment condition (corresponding to the first condition), and uploads a file (corresponding to the synchronization data) to the cloud server through the internet at an appropriate time;

specific examples thereof are: the terminal B (mobile phone) will regularly detect whether the following conditions are met:

(1) The electric quantity of the mobile phone is larger than a certain threshold (if the electric quantity is larger than 20%), or the mobile phone is in charging; corresponding to the residual capacity being larger than a first threshold value or in a charging state;

(2) At the moment, the system is in a wifi network environment instead of a data network; corresponding to the connection to the wireless network;

(3) At this time, the temperature of the mobile phone is lower than a certain threshold (for example, the temperature is lower than 45 ℃); corresponding to the temperature of the equipment being lower than a second threshold value;

(4) At the moment, the mobile terminal is not in a game scene or other scenes with higher network bandwidth requirements; corresponding to the required network bandwidth being below a third threshold.

After the at least one condition is met, the terminal B (mobile phone) starts to upload the specific file content (corresponding to the above-mentioned synchronization data) to the server, and meanwhile, the GUID of the file is taken, and the GUID of the file is allocated by the cloud server in the pre-upload process of the operation 1 in this section.

If the condition is not satisfied, the system enters a waiting state, and the timer triggers the next time to detect the condition again.

Section 3 relates primarily to the following:

operation 1, downloading data to a cloud server through the internet.

And the terminal A (computer) sends a request to the cloud server at regular time through the Internet, and detects data updating. And if the cloud data update exists, downloading new data. Specific examples thereof are: the terminal A sends a detection request to the cloud server, the cloud server feeds back a detection response to the terminal A under the condition that the cloud server determines that the cloud server is updated, the terminal A sends an update request to the cloud server according to the detection response, and the cloud server sends data to the terminal A according to the update request; sending an information synchronization request (carrying a data identifier) to a cloud server; and receiving data information of the synchronous data sent by the cloud server.

The "downloading new data" may include the following items:

(1) The text type data is downloaded.

(2) The file information (i.e., the above-mentioned file summary information) is downloaded, and a file icon is displayed according to the file information, as shown in fig. 6.

The file information may include a file size, a last modification date, a file name, a file type, and a thumbnail, and at this time, the terminal a (computer) interface may display a file icon according to the file information.

Operation 2, the terminal a (computer) downloads the specific content of the file according to the GUID in the file information, as shown in fig. 6. This may be triggered by a user or performed automatically, without limitation.

Before downloading the file (specific content), it may be determined whether a local area network connection is made with the terminal B (mobile phone) (corresponding to the above determination of whether the first electronic device is connected to the second electronic device through the local area network), and if the local area network connection is not established, the operation 2 of the part 1 may be returned to, and an automatic connection is attempted. The lan connection is specifically a connection established through the router.

(1) If the local area network is accessed, the file is automatically downloaded through the local area network, the file GUID is sent to the terminal B (mobile phone), and the file downloading is requested. Corresponding to the situation that the first electronic device is connected with the second electronic device through the local area network, sending a data synchronization request to the second electronic device through the local area network; and receiving the synchronous data sent by the second electronic equipment through the local area network.

(2) And if the mobile terminal does not enter the local area network, sending a file GUID to the cloud server through the Internet to request to download the file. Corresponding to the situation that the first electronic device is not connected with the second electronic device through the local area network, sending a data synchronization request (carrying a data identifier) to a cloud server; and receiving the synchronous data sent by the cloud server.

Operation 3. If during the downloading of the file (specific content), network switching is found, such as the following scenarios:

in the process of downloading the file by the local area network, the mobile phone is disconnected in the local area network, the breakpoint position (corresponding to the second breakpoint information) is recorded, and the internet cloud service is switched to try to continue downloading from the breakpoint. When the interruption of target connection is detected in the process of receiving the synchronous data sent by the second electronic device through the local area network, recording second breakpoint information of the synchronous data; sending a data synchronization request (carrying a data identifier) to a cloud server according to the second breakpoint information; and receiving the synchronous data which is sent by the cloud server and starts from the second breakpoint.

If the mobile phone is accessed to the local area network in the process of downloading the file through the internet, after the connection is automatically found through the operation 2 of the part 1, the internet downloading is suspended, and the breakpoint (corresponding to the first breakpoint information) is recorded. And switching to the local area network to continue downloading from the breakpoint, so as to accelerate the downloading speed. In the process of receiving the synchronous data sent by the cloud server, when the first electronic device is detected to be connected with the second electronic device through the local area network, the receiving of the synchronous data is suspended, and first breakpoint information of the synchronous data is recorded; according to the first breakpoint information, sending a data synchronization request (carrying a data identifier) to the second electronic device through the local area network; and receiving the synchronous data which is sent by the second electronic equipment through the local area network and starts from the first breakpoint.

And operation 4, in the file downloading process, the user opens the file and prompts the user to open the file until the downloading is completed.

The above description is not limited to the execution in the above order, and is not limited herein.

From the above, the scheme provided by this example has the following effects:

1. the specific content of the large file (namely the file type data) is transmitted through the local area network, and compared with the transmission by using the internet, the method has the advantages of being more stable and faster in transmission speed.

2. The terminal B (mobile phone) can delay uploading of specific file contents and delay uploading after the requirements of electric quantity, power consumption, data network flow and user use scenes are met; the effects of power saving and temperature control are achieved.

3. If the local area network condition is met (namely, the file is connected through the local area network), the terminal A (computer) can immediately download the file from the terminal B (mobile phone), and the time for uploading the file to the cloud service and the time for delaying the uploading of the file do not need to be waited for.

4. Under the condition of local area network transmission, the scheme improves the synchronization speed of the large file data and also improves the real-time property of the synchronization of the large file data.

Example two (corresponding to the second networking approach described above):

assume that both terminal a (computer) and terminal B (mobile phone) have logged in the same data account (data account for synchronization) and have accessed the internet as shown in fig. 7; both ends (terminal A and B) all have bluetooth module and wireless network card, support wifi p2p to be connected. A cloud server exists to provide centralized synchronization services for multiple device terminals.

Based on the above, the overall scheme is mainly divided into three parts: part 1, establishing local area network connection (equipment networking, wifi p2p connection); part 2, uploading data by a terminal B (mobile phone); part 3, terminal a (computer) downloads data.

Section 1 relates primarily to the following:

operation 1, connection is established between a terminal A (computer) and a terminal B (mobile phone) for the first time.

In the scheme, a terminal B (mobile phone) can externally send a broadcast through the low power consumption bluetooth BLE, and the broadcast content includes device information and account information (information of the data account can be used to determine whether to log in the same account) of its own device. After scanning nearby BLE broadcasts through BLE, the terminal a (computer) judges whether the account information of the other party is the same account as the local phone, and if so, the terminal B (mobile phone) is displayed in an equipment list, as shown in fig. 8. And clicking the equipment in the equipment list by the user, so that the point-to-point wifi p2p connection can be established with the equipment.

After the wifi p2p connection is established successfully for the first time, the ID of the equipment which is successfully connected for the last time can be recorded in the database.

And 2, establishing connection between the terminal A (computer) and the terminal B (mobile phone) for the non-first time.

If the 'subsequent automatic connection' is selected during the first connection, when the terminal A (computer) and the terminal B (mobile phone) approach to the Bluetooth discovery range, the Bluetooth search discovery is performed according to the mode in the operation 1. After discovering the device list and before displaying the device list, the terminal a may obtain the ID of the opposite device that has successfully connected for the last time from the database, and query the ID from the device list. And if the device ID exists in the device list, automatically carrying out wifi p2p connection (direct connection is successful). Otherwise, displaying the device list.

Section 2 relates primarily to the following:

As shown in fig. 9, after each data generation, data synchronization (including dividing the data into the above two types for uploading) is triggered. Judging whether the terminal (namely the terminal B) is accessed to the Internet or not, and if so, uploading text type data to a server (corresponding to the cloud server); after the text type (data) is uploaded, the file of each file type data needs to be pre-uploaded, and the pre-uploading is used for uploading a small amount of summary information (corresponding to the data information) of the file in advance, so that other terminals can display icons and basic information (such as file size, file name, final modification time and the like) of the file on an interface under the condition that the specific content of the file is not uploaded or downloaded. The pre-upload content may include file summary information (corresponding to the above data information) such as a file name, a file size, a file type, a thumbnail, and the like, but does not include specific file content. Dividing the data to be synchronized into text type data and file type data correspondingly; according to the file type data, determining synchronous data and data information of the synchronous data; and uploading the data information of the text type data and the synchronous data to a cloud server.

The server analyzes the file summary information when the files are pre-uploaded, generates a GUID (globally unique identifier corresponding to the data identifier) for each file, and returns the GUID to the client terminal B (mobile phone). The GUID is a unique identifier of each file in the cloud server, and through the GUID, a certain file under a certain user (account) can be located, so that the GUID is used for binding the summary information pre-uploaded by the file with a file body and locating the file.

(1) The text type data is downloaded.

(2) The file information (i.e., the above-mentioned file summary information) is downloaded, and a file icon is displayed based on the file information, as shown in fig. 10.

Operation 2, the terminal a (computer) downloads the specific content of the file according to the GUID in the file information, as shown in fig. 10. This may be triggered by a user or performed automatically, without limitation.

Before downloading the file (specific content), it may be determined whether a lan connection is made with the terminal B (mobile phone) (corresponding to the above determination of whether the first electronic device is connected to the second electronic device via the lan), and if a lan connection is not established, the operation 2 of the part 1 may be returned to, and an automatic connection is attempted. The local area network connection is specifically the wifi p2p connection.

And operation 4, in the file downloading process, the user opens the file and prompts the user to open the file only after the downloading is finished.

From the above, the scheme provided by this example has the following effects:

3. If the local area network conditions are met (namely, the files are connected through the local area network), the terminal A (computer) can immediately download the files from the terminal B (mobile phone), and the time for uploading the files to the cloud service by the terminal B (mobile phone) and the time for delaying uploading are not required to be waited.

5. When the terminal of the user is not in the same router or local area network environment, the wifi p2p and the low-power Bluetooth can be used for discovering and connecting the equipment, and after the connection is successful, the equipment is in the same local area network, so that data transmission is carried out through the local area network.

In this description, the present solution:

1. the terminal A (computer) and the terminal B (mobile phone) can establish connection through a router or a mobile hotspot or directly establish wifi p2p connection, thereby forming the same local area network.

2. After a terminal A (computer) and a terminal B (mobile phone) user are connected and authorized through a local area network for the first time, the two devices can be automatically connected and automatically synchronized as long as the two devices are in the same local area network.
