Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of communication, and more particularly, to a method, apparatus and terminal device for synchronizing data. BACKGROUND

[0002] A terminal device (or a center device) can be combined with other terminal devices in the surrounding environment to conveniently obtain services provided by the other terminal devices or provide services to the other terminal devices. For example, a multi-screen collaboration can be started by combining a mobile phone and a notebook computer, a screen projection for watching a movie can be realized by combining a mobile phone, a headset and a smart screen, and a distributed camera can be realized by combining a mobile phone and a tablet computer.

[0003] To support the implementation of the function, the center device needs to synchronize data with other terminal devices in the surrounding environment. When the number of terminal devices in the environment is large, a data synchronization concurrency phenomenon is likely to occur, that is, the center device simultaneously synchronizes data with two or more terminal devices, which further leads to a prolonged time delay of data synchronization and a reduced data synchronization rate with an increase in the number of concurrent devices. If the center device has data transmission or other interference, the time delay of data synchronization is further increased, and the connection success rate between the center device and other terminal devices is reduced, which eventually leads to a large amount of time required by the center device to establish a connection with other terminal devices.

The device types that have a combination relationship with the device M can be the same as the device types corresponding to the device M, or can be different.

[0095] The device M can not only construct a combination or establish a connection with one device having a combination relationship to realize a distributed service, but also can construct a combination with two or more devices simultaneously to realize a distributed service. For example, the device M is a mobile phone, which can construct a combination with a headset and a large-screen device simultaneously, and can play a video image on the mobile phone on the large-screen device and listen to audio with the headset to realize screen projection and watching.

[0096] The following describes Figure 4 A method for synchronizing data is introduced, which includes steps S401 and S402.

[0097] S401, the first device determines that there is a combination relationship with the second device according to device combination information, the device combination information includes device information having a combination relationship with the first device, and the first device and the second device have a combination relationship, which means that the first device and the second device can support one or more distributed services together.

[0098] S402, the first device synchronizes data of the second device from the second device.

[0099] The first device can be the device M, the second device can be a device around the first device, and the second device can be any one of the device types one, two and three having a combination relationship with the device M. The first device can determine whether there is a combination relationship with the second device according to the device combination information. If there is a combination relationship between the first device and the second device, the first device synchronizes data of the second device from the second device. If there is no combination relationship between the first device and the second device, the first device does not need to synchronize data of the second device from the second device.

[0100] The second device can be any one of the devices around the first device. After the first device discovers the devices around the first device, the first device can select any one of the devices around the first device, and then determine whether there is a combination relationship with the selected device according to the device combination information. If there is a combination relationship, the first device determines that data of the selected device needs to be synchronized. If there is no combination relationship, the first device determines that data of the selected device does not need to be synchronized.

[0101] The first device can also determine which devices around the first device have a combination relationship with the first device according to the device combination information, and then select any one of the devices having a combination relationship with the first device to synchronize data of the selected device. That is, the second device can also be any one of the devices around the first device having a combination relationship with the first device.

[0102] In some embodiments, before the first device performs step S401, the first device can send a first broadcast message, which can be used to discover peripheral devices of the first device. Accordingly, after receiving the first broadcast message, the peripheral devices can send a first response message to the first device, so that the first device knows which terminal devices exist in the peripheral environment, including the types of the terminal devices. Further, the first device determines which devices have a combination relationship according to the device combination information, and synchronizes data with the devices having a combination relationship.

[0103] The first broadcast message can be a Bluetooth broadcast message. The data of the second device synchronized by the first device can include an account, configuration, and service data of the second device, and the like, which are not limited in the present application.

[0104] In some embodiments, the method further includes: the first device verifying the data of the second device. After the first device synchronizes the data of the second device, the first device and the second device can generate a data verification code, and the first device can verify whether the generated data verification code is the same as the data verification code generated by the second device. If the data verification codes generated by the two devices are the same, it means that the data synchronization is successful, and if they are not the same, the data synchronization fails, and there can be data loss, data collision, or data expiration, and the like, and the data synchronization can be performed again.

[0105] Through the embodiments provided in the present application, the terminal device can determine whether there is a combination relationship with the peripheral devices based on the device combination information, synchronize the data of the devices having a combination relationship, and the data of the devices not having a combination relationship does not need to be synchronized, thereby being able to filter the peripheral devices, reduce the number of data synchronization and the amount of data synchronization, reduce the time delay of data synchronization, improve the efficiency of data synchronization, and further improve the success rate and stability of device connection.

[0106] In some embodiments, the first device can not only synchronize the data of the second device from the second device side, but also synchronize the data of other devices having established a connection with the second device from the second device side. Figure 5 is a schematic diagram of an example of a device combination relationship provided by the embodiments of the present application, as shown in Figure 5 The device M can discover the above devices through a first broadcast message, and the bidirectional arrow between the devices indicates that there is a combination relationship between the two devices. If the device M determines that there is a combination relationship with the device A, and the device M can synchronize the data of the device A from the device A side, as shown in Figure 4The steps performed by the first device and the second device in the described method, the first device can be device M, and the second device can be device A. Device M can also synchronize data of other devices from device A. The following describes the method of synchronizing data of other devices from device A by device M. Figure 6 Another method of synchronizing data provided by the present application is introduced as follows. Figure 6 As shown in the method, the method can include steps S601-S603.

[0107] S601, device M determines, according to device combination information, that there is a combination relationship with device B.

[0108] The device B is a third device, which can be a device that has established a connection with device A, or in other words, device A has synchronized data of device B. In other words, as shown in the following, device A and device B have a combination relationship and can jointly support one or more distributed services. Figure 5

[0109] S602, device M synchronizes data of device B from device A.

[0110] In some embodiments, device M can determine, according to device combination information, whether device M has a combination relationship with device A and device B respectively when discovering peripheral devices including device A and device B. After device M synchronizes data of device A from device A, if there is data of device B at device A, device M can continue to synchronize data of device B from device A.

[0111] In some embodiments, device M can first determine that there is a combination relationship with device A and synchronize data of device A from device A, and then determine whether device M has a combination relationship with device B, and further determine whether data of device B needs to be synchronized.

[0112] In some embodiments, device M determines that there is no combination relationship with device A, but device A has established a connection with device B and stores data of device B. Device M can not synchronize data of device A, but synchronize data of device B from device A.

[0113] Similarly, the data of device B can include account, configuration, and service data of device B.

[0114] S603, device M verifies data of device B.

[0115] ​After synchronizing data from device B from device A, device M can generate a data checksum and determine if it matches the checksum generated by device A. If they match, data synchronization is successful; otherwise, synchronization fails, and the process restarts. Alternatively, when device A synchronizes data from device B, it can generate and store the checksum. When device M synchronizes data from device A from device B, it uses the stored checksum and the checksum generated by device M to perform data verification. This application does not limit the method of data verification.

[0116] It should be understood that the steps for device A to synchronize data with device B can be similar to the steps for device M to synchronize data with device A. In other words, after discovering device B, device A can directly synchronize the data of device B from device B. Alternatively, similar to the steps for device M to synchronize the data of device B, device A can synchronize the data of device B from other devices. This application does not limit this.

[0117] In some embodiments, device A may synchronize not only data from device B, but also data from other devices such as device C and / or device D. Further, device M can determine whether it has a combination relationship with device C and / or device D based on device combination information, and thus determine whether data synchronization with device C and / or device D is necessary. Similarly, if device A synchronizes data from device C, it indicates that device A and device C have a combination relationship and can jointly support one or more distributed services.

[0118] As an example, such as Figure 5 As shown, device A and device C are in a combination relationship and device A has data from device C synchronized. If device M determines that device M and device C are not in a combination relationship, then device M does not need to synchronize data from device C from device A.

[0119] As another example, such as Figure 5 As shown, device A and device D are not combined, and device A has not synchronized data from device D. If device M determines that it is combined with device D, then device M can synchronize the data of device D from device D after synchronizing the data of device A and device B. The process of device M synchronizing the data of device D is similar to the steps of device M synchronizing the data of device A, that is, similar to steps S401 to S402 of the first device synchronizing the data of the second device mentioned above, and will not be repeated here.

[0120] Similar to how device M synchronizes data from device A to device B, when device M synchronizes data from device D to device D, device M can also synchronize data from device D to devices that have a combination relationship with both device M and device D, and perform data verification.

[0121] The device M and the device A, the device B and the device D can be the same type of device, for example, can all be a mobile phone, or can be different types of devices, for example, the device M is a notebook computer, the device A is a tablet computer, and the present application does not limit the number or type of devices that the device M can synchronize data.

[0122] The device M, the device A, the device B, the device C and the device D described above are only used as an example to illustrate the method of the device M synchronizing the data of the peripheral device, and should not be limited to the number or type of devices that the device M can synchronize data.

[0123] The method for synchronizing data provided by the embodiments of the present application can synchronize the data of other devices from one device when a device joins a new multi-device environment, greatly reducing the number of data synchronization, reducing the time delay of data synchronization, avoiding the problems of connection failure or long connection time when the number of peripheral terminal devices is large, improving the success rate and stability of device connection, and optimizing the user experience. For example, the device M discovers that the devices with which it has a combination relationship in the periphery are the device A and the device B, and the device M does not need to establish a connection with the device A and the device B respectively and synchronize data, but can only establish a connection with the device A, synchronize the data of other devices (such as the device B) from the device A to reduce the number of data synchronization and the number of device connections, and improve the success rate and stability of device connection.

[0124] In some embodiments, after the device M synchronizes the data of other devices, it can store the synchronized data in a cache area or memory, or upload the synchronized data to a server. So that the next time the user brings the device M into the environment, after the device M discovers the device whose data has been synchronized, it can directly call the data of the device from the local or cloud, without occupying the data synchronization channel to re-synchronize the data of the device, and only needs to synchronize the data with new devices that have not been synchronized, thereby further improving the success rate and stability of device connection.

[0125] Storing the data of the device in the local can improve the speed of calling the data synchronization of the device, and after the user leaves the current environment for a short time and returns, there is no need to re-synchronize the data, and the cache data occupies less storage space of the device. Uploading the data of the device to the server, for example, saving the data under the user account in the cloud, does not occupy the storage space of the device, and can store a large amount of device synchronization data. When the device is restored to factory settings and reconfigured, the device data can be directly downloaded from the cloud without re-synchronizing the data.

[0126] Optionally, after the user downloads the synchronized data from the cloud, the downloaded data can also be verified in the cloud.

[0127] After the method for synchronizing data provided in the embodiments of the present application is used, the "super terminal" interface of the terminal device can quickly and stably display the peripheral devices, and thus the combination of the center device and the peripheral devices and the device cooperative operation can be realized, and the distributed service can be realized. Figure 7 is a schematic diagram of a user interface of a terminal device provided in the embodiments of the present application, Figure 7 The center device, that is, the device M, is taken as a mobile phone as an example for introduction, and the device M can also be a notebook computer or other terminal device. As shown in Figure 7 (a), after the device M synchronizes data with the devices in the peripheral environment that have a combination relationship, the devices with synchronized data are quickly and stably presented on the user interface. The devices A, B and the devices D, E and F can be devices that have synchronized data with the device M through the method for synchronizing data described in the above embodiments, and the devices that do not have a combination relationship with the device M, such as the device C in the above method embodiments, can not be presented in the interface, so that the user can clearly know which devices in the peripheral environment can build a combination with the center device M and realize device cooperation.

[0128] Further, the user can select the required device from the presented devices according to actual use requirements, and build a combination with the center device M. For example, the user can pull or drag the required device, such as the device A, to the position of the device M, as shown in Figure 7 (b), so that the device M builds a combination with the device A.

[0129] Figure 7 (c) takes a camera as an example to introduce the task flow method of the device M and the device A after the device M builds a combination with the device A. As shown in Figure 7 (c), when the user opens the camera application, a prompt information can be displayed on the camera application interface, for example: click to transfer the "camera" application to the device A. Further, in response to the user clicking the prompt box, the device M can call the camera of the device A, and the image collected by the camera of the device A can be displayed in the image collection area of the camera of the device M (not shown in the figure), and the distributed photographing service can be realized. The distributed camera service is a distributed service that can be supported by the device M and the device A together, and the information of the distributed service can be included in the device combination information of the device M and / or the device A.
