Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In order to improve the instantaneity of acquiring the application program, the embodiment of the invention provides a data acquisition method which is mainly applied to a mobile device side. As shown in fig. 1, the method includes:

101. after the computing device establishes the wireless hotspot through the wireless network card, the mobile device joins the local area network of the wireless hotspot.

The computing device firstly establishes a wireless hotspot through a wireless network card, establishes a local area network through the wireless hotspot, and adds the flow cost of the device added into the local area network to the wired bandwidth of the computing device.

In addition, when the mobile device joins the local area network, the mobile device needs to search the local area network which can be joined, and correctly input the password for joining the network, and when the local area network authenticates the mobile device, the mobile device joins the local area network.

102. The mobile device establishes a wireless connection with the computing device over the local area network.

Generally, a plurality of user devices may be added to a local area network, and after the mobile device is added to the local area network, the mobile device cannot directly communicate with a computing device, and needs to establish a wireless connection with the computing device.

In one implementation of the embodiment, the mobile device establishes a wireless connection by pairing with the computing device. The mobile device may be paired with the computing device through a mobile device client or user account. For the former implementation, the mobile device connects through a locally installed mobile device client and a computing device side installed mobile device client. Specifically, the mobile device sends a connection request to the mobile device client on the computing device side through the local mobile device client, and the computing device pops up a prompt box to the user after receiving the request to inquire whether the user establishes wireless connection with the mobile device. When the user selects to establish the wireless connection, the mobile device client on the computing device side sends a connection response to the mobile device client on the mobile device side, thereby completing the establishment of the wireless connection. For the latter implementation, the user first needs to log in a personal account through the computing device, and when a wireless connection with the mobile device needs to be established, the user can log in the same personal account on the mobile device. After recognizing that the personal accounts on the two devices are communicated, the network side server sends a confirmation instruction to the computing device, and the computing device sends a connection response to the mobile device according to the instruction to complete the establishment of the wireless connection.

103. The mobile device sends a data acquisition instruction to the computing device based on the wireless connection.

After the wireless connection is established, all data interaction processes between the mobile device and the computing device will be completed based on the wireless connection. Specifically, the mobile device sends a data acquisition instruction to the computing device via a wireless connection. The data acquisition instruction is used for acquiring an application program currently running in the computing device, when a user needs to use an application in the computing device on the mobile device, the data acquisition instruction can be triggered on the mobile device, and the mobile device sends the received instruction to the computing device.

In this embodiment, the mobile device may obtain the data obtaining instruction triggered by the user in the form of signals such as sound, light, and electricity by using built-in components with different functional characteristics. For example, the mobile device may collect an acoustic signal sent by the user through a microphone, and when the user sends a preset voice instruction (e.g., some keywords), the mobile device obtains a data acquisition instruction; or, for the touch screen device, the mobile device may also receive a touch electrical signal triggered by a user through the touch screen, and thereby obtain a data acquisition instruction; or, the mobile device can also recognize and acquire the gesture operation of the user by monitoring the intensity of the external light, and thus acquire the data acquisition instruction. The present embodiment does not limit the carrying form and the obtaining manner of the instruction.

It should be noted that the application program currently running in the computing device in this embodiment refers to a device-side application that is running in the computing device at the time of receiving the data acquisition instruction, and the applications include:

1. application of operation focus

For example, when a data acquisition instruction is received, the operation focus in the computing device is located on an application icon of a certain application or on a folder icon of the application, and the application is a running device-side application. The operation focus includes a cursor controlled by a mouse, or for a touch screen computing device, the operation focus also includes a touch point triggered by a user finger on a touch screen.

2. Application of ongoing network data transmission

For example, when a data acquisition instruction is received, an application in the computing device is downloading music or uploading photos, and the application is a running device-side application regardless of whether the application runs in the foreground or not.

3. Application for editing data

For example, when a user inputs data information (e.g., records text information in a notepad) in an application in the computing device when receiving a data acquisition instruction, the application is a running device-side application.

4. Applications occupying system resources above a preset threshold

Upon receiving the data acquisition instruction, if one or more applications are opened in the computing device, the applications with system resources exceeding a preset threshold (e.g., exceeding 60%) are running device-side applications.

104. And the mobile equipment receives the application identification sent by the computing equipment according to the data acquisition instruction.

After sending the data acquisition instruction to the computing device, the computing device locally searches the currently running device-side application, and sends the application identifier of the device-side application to the mobile device. In this embodiment, the application identifier includes an identity identifier of an equipment application running on the computing device when the computing device receives the data acquisition instruction, where the identity identifier is used to uniquely mark the application program, and the identity identifiers of different application programs are different from each other. In practical application, the identity may be, but not limited to, an information Digest Algorithm 5 (MD 5 for short), a digital signature, an application name, an application version number, and the like, and all strings and pictures (for example, two-dimensional codes) capable of playing a role of uniquely identifying an application may be used as the identity, and the specific form of the identity is not limited in this embodiment.

Unlike the conventional data transmission method, in this embodiment, the data content received by the mobile device is not the application program itself, but the application identifier of the application program. The design aims to reduce the data transmission quantity between devices and improve the instantaneity of application program transmission and the use efficiency of users. In addition, the application identifier can be transmitted in a manner of avoiding repeated transmission of data content and saving network resource overhead under the condition that the same application program is downloaded in the mobile device. Of course, in practical applications, the application itself may also be directly transmitted between the mobile device and the computing device, which is not limited in this embodiment.

For the data transmission, the mobile device and the computing device may transmit the application identifier in a wired or wireless manner, and at the same time, the data acquisition instruction in step 103 may also be sent based on the same data transmission manner as in this step. For the wired transmission mode, the mobile device can establish a data interaction relation with the computing device through a data line, and for the wireless transmission mode, the mobile device and the computing device can establish a data interaction relation in a mode of establishing a wireless network. In practical applications, the wireless transmission modes include, but are not limited to: wireless fidelity (Wi-Fi) transmission, infrared transmission, bluetooth (bluetooth) transmission, wireless fidelity direct (Wi-Fi direct) transmission, Near Field Communication (NFC) transmission, Radio Frequency (RF) transmission, and home Radio Frequency (homeRF) transmission.

In addition, the mobile device may also receive an application identifier sent by the computing device in a conventional communication manner, for example, in a form of a short message, and the data transmission manner adopted between the devices is not limited in this embodiment.

105. And the mobile equipment starts the mobile terminal application corresponding to the application identification.

After obtaining the application identifier, the mobile device searches and starts the mobile terminal application corresponding to the application identifier. In this embodiment, the mobile application and the device application are respectively adapted to different system operating environments, and the system operating environment may be an operating system or a programming language. For example, the device side application may be adapted to an XP or Win8 operating system, while the mobile side application may be adapted to an android, saiban, or IOS operating system; or, the device side application can adapt to the system running environment developed by the C language, the C + + language or the VB language, and the mobile side application can adapt to the system running environment developed by the JAVA language.

In addition, although the mobile-side application is adapted to a different system operating environment than the device-side application, both have the same identity characteristics in whole or in part or have recognizability characteristics above a threshold. In this embodiment, the identity features include, but are not limited to: developer name, category of belongings, development time, application name, version number, digital signature, or application description. The identity feature may be one or a combination of multiple kinds of attribute information, or may be an MD5 value generated by the multiple kinds of attribute information, and the form of the feature information is not limited in this embodiment.

The identifiability features include, but are not limited to, similarities of control interfaces, operator interfaces, installation interfaces, guidance interfaces, departure interfaces, or content presentation interfaces. The legibility characteristic higher than the threshold means that the similarity between the device-side application and the mobile-side application is higher than a preset threshold, where the threshold may be a proportional value used for representing the interface style layout similarity, for example, 60% or 85%, and the proportional value may be used for reflecting the overall similarity of the interface, or may be used for reflecting the similarity of an independent element in the interface (for example, a function of a certain button or a display position of an advertisement, etc.), and the embodiment does not limit the specific form of the legibility characteristic. The similarity of the identifiable characteristics can be obtained by comparing a Cascading Style Sheet (CSS), a JS script Language, or a Hypertext Markup Language (HTML).

When the mobile terminal application is started, the mobile device firstly searches whether the mobile terminal application which is installed and corresponds to the application identification exists locally. And if the mobile end application which is installed and corresponds to the application identifier is found, the mobile equipment starts the mobile end application, and if the mobile end application which is installed and corresponds to the application identifier is not found, the mobile equipment acquires an installation package of the mobile end application corresponding to the application identifier and carries out local installation.

In this embodiment, the following ways of obtaining the application installation package of the mobile terminal may be used:

1. the mobile equipment searches the installation package locally at the mobile terminal side.

And if the mobile equipment locally stores the installation package corresponding to the application identifier, the mobile equipment searches and acquires the installation package according to the storage path.

2. The mobile device receives an installation package sent by the computing device.

If the mobile device does not locally store the installation package corresponding to the application identifier, the mobile device may request the computing device to acquire the installation package, or receive the cover installation package sent by the computing device together when receiving the data acquisition instruction.

3. The mobile device requests the network side to download the installation package.

As an alternative to the above mode 2, the mobile device may also request the network device to download the installation package corresponding to the application identifier. When requesting for the installation package, the mobile device may carry the identity of the application in a data request and send the data request to the network side, so that the network side searches for and issues the installation package.

In the data obtaining method provided in this embodiment, after the mobile device and the computing device establish a wireless connection through the local area network, the mobile device obtains, from the computing device, an application identifier of a device side application currently running on the computing device based on the wireless connection, and locally starts a mobile side application corresponding to the application identifier, so that a user can use an application program on the computing device side on the mobile device side. Compared with the prior art that the user manually searches/downloads the application program, the method and the device can realize the quick transfer of the application program based on the wireless local area network between the devices, so that the user can conveniently select different devices to operate the application program, thereby ensuring the instantaneity of obtaining the application program and improving the use efficiency of the user.

In addition, the data acquisition method provided by this embodiment can also replace the implementation manner of transmitting the data content itself by the manner of transmitting the application identifier, so that the resource overhead of the network can be saved, and the repeated transmission of the data can be prevented.

Furthermore, in order to improve the instantaneity of acquiring the application program, the embodiment of the invention also provides a data acquisition method, and the method is mainly applied to a computing device side. As shown in fig. 2, the method includes:

201. the computing device establishes a wireless hotspot through a wireless network card.

202. After the mobile device joins the local area network of the wireless hotspot, the computing device establishes a wireless connection with the mobile device through the local area network.

The implementation manners of step 201 and step 202 are the same as the implementation manners of step 101 and step 102 in fig. 1, and are not described herein again. After establishing the wireless connection, the computing device is paired with the mobile device over the local area network.

203. Based on the wireless connection, the computing device receives a data acquisition instruction sent by the mobile device.

Similar to step 103 of fig. 1, the data obtaining instruction is used to obtain an application currently running in the computing device, where the application is a device-side application running in the system environment of the computing device.

204. And the computing equipment searches the running equipment end application in the current computing equipment according to the data acquisition instruction.

The application program currently running in the computing device in this embodiment refers to a device-side application that is running in the computing device at the time of receiving the data acquisition instruction, and the applications include:

1. application of operation focus

2. Application of ongoing network data transmission

3. Application for editing data

4. Applications occupying system resources above a preset threshold

Based on the above requirements, the device-side application currently running searched by the computing device in this embodiment includes:

a. device-side application with highest display hierarchy in current computing devices

When multiple device-side applications are running simultaneously in the computing device, the computing device may find the device-side application at the uppermost display level.

b. Device side application with current operation focus

The operation focus comprises a cursor and a touch point, and the computing equipment can search the equipment end application through the position of the operation focus.

c. Equipment end application with current system resource occupation exceeding preset threshold

For different device-side applications currently running, the computing device may find a device-side application whose system resource occupancy exceeds a preset threshold, for example, find a device-side application whose system resource occupancy exceeds 10% or find a device-side application whose system resource occupancy exceeds a pre-allocated system resource. Transferring the device end application with excessive system resource occupation to the mobile device for running can release part of the system resource on the computing device side and reduce the system resource load on the computing device side.

d. Equipment end application with current network bandwidth occupation exceeding preset threshold

For the online application, the computing device may further search for a device-side application whose network bandwidth occupancy exceeds a preset threshold, and transfer the device-side application to the mobile device side for operation, thereby relieving the bandwidth pressure on the computing device side.

e. And the device side application displayed in full screen currently.

In addition to the above 4 ways, the computing device may also search for the device-side application currently displayed foreground full screen.

205. The computing device sends the application identification of the running device-side application to the mobile device over the wireless connection.

After finding the currently running device-side application, the computing device obtains an identity (e.g., an MD5 value, a digital signature, etc.) of the device-side application, and then adds the identity to the application identifier and sends the application identifier to the mobile device, so that the mobile device starts the mobile-side application corresponding to the application identifier.

Similar to step 104 in fig. 1, in this step, the computing device may send the application identifier to the mobile device through a wired or wireless transmission manner, or send the application identifier in a form of short message through a conventional communication network.

The data acquisition method provided in this embodiment can determine, by the computing device, the device side application that is running locally after the mobile device and the computing device establish a wireless connection through the local area network, and send the application identifier of the device side application to the mobile device, so that the mobile device starts the mobile side application corresponding to the application identifier, thereby enabling a user to use an application program on the computing device side on the mobile device side. Compared with the prior art that the user manually searches/downloads the application program, the method and the device can realize the quick transfer of the application program based on the wireless local area network between the devices, so that the user can conveniently select different devices to operate the application program, thereby ensuring the instantaneity of obtaining the application program and improving the use efficiency of the user.

In practical applications, the mobile device described in the above embodiments may be, but is not limited to, a mobile phone or a portable computer; the computing device may then be primarily a PC. In order to better explain the embodiments of the present invention, in the following, the embodiments of the present invention will be explained from both sides of the mobile device and the computing device by taking a mobile phone and a PC as examples. As shown in fig. 3, a method for acquiring data provided by an embodiment of the present invention includes:

301. the PC establishes a wireless hotspot through a wireless network card.

302. The mobile phone joins the local area network of the wireless hotspot.

303. The PC establishes wireless connection with the mobile phone through the local area network.

304. And pairing the mobile phone and the PC.

305. And the mobile phone sends a data acquisition instruction to the PC.

As described above, the mobile phone may provide different instruction triggering manners for the user by combining the device characteristics of the mobile phone, and in an embodiment of the present invention, the mobile phone may enable the user to trigger the data acquisition instruction by shaking the mobile phone through monitoring of the motion sensor, and when the user shakes the mobile phone according to the preset condition (for example, shakes the mobile phone once or shakes the mobile phone twice, etc.), the mobile phone obtains the data acquisition instruction and sends the instruction to the PC.

When judging whether a user shakes the mobile phone, the mobile phone can monitor whether the mobile phone is in a shaking state through the motion sensor, if so, the mobile phone obtains shaking data from the motion sensor, and judges whether the shaking data meets a preset condition. And if the preset conditions are met, recognizing a data acquisition instruction and sending the instruction to the PC.

The preset condition in this embodiment is to limit the shake data, which is used to distinguish between accidental shaking and shaking intended by the user, or may also be used to distinguish between shaking for other operating functions and shaking for data acquisition in this embodiment. The preset condition may be set by the user through shaking of the mobile phone in the setting stage, for example, the preset condition may be set to "shake once", "shake twice" or "shake three times" or the like.

In practical applications, the motion sensor may be, but is not limited to, a gravitational acceleration sensor, and when the mobile phone shakes, the sensor may detect the generation of acceleration and may obtain the direction of the acceleration. When the preset conditions are set, the mobile phone can set the preset conditions according to shaking data (whether acceleration is generated, the magnitude and direction of the acceleration and the like) returned by the sensor. In a feasible scheme of this embodiment, since the gravitational acceleration sensor can detect not only whether the gravitational acceleration is generated, but also the magnitude of the gravitational acceleration, the mobile phone can also distinguish the intensity of the shaking of the user according to the obtained specific shaking data, thereby enriching the number of shaking instructions. Generally, the gravity acceleration generated by a user shaking the mobile phone lightly is smaller than that generated by shaking the mobile phone vigorously, and when a preset condition is set, the mobile phone can divide the gravity acceleration into intervals, so that the user is allowed to set the shaking action of the data acquisition instruction to be stronger and set the shaking action of another function to be weaker, and therefore two different operations are distinguished. Along with the continuous increase of the functions of the mobile phone, limited shaking operation types cannot meet the increasing functions, in the scheme, the mobile phone can develop a new method in the dimension of the gravity acceleration (the strength of shaking in the user using layer) and combines the existing shaking operation to expand the quantity of the shaking operation in multiples, so that the operation mode of the mobile phone is enriched.

In another embodiment of the present invention, the mobile phone may further monitor a trigger state of a preset key, where the preset key may be a physical key or a virtual key. When the user triggers the preset key, the mobile phone obtains a data acquisition instruction and sends the instruction to the PC.

Optionally, in order to further meet the requirements and preferences of the user, the mobile phone further allows the user to set the preset key in advance, for example, a certain key is selected as the preset key in the setting menu, or when the user presses a certain key (including a physical key and a virtual key) for a long time and the time exceeds a preset time, the mobile phone automatically sets the key as the preset key. The setting manner of the preset keys in this embodiment is only an exemplary illustration, and is not limited to the specific implementation manner in the practical application.

In another embodiment of the present invention, for a touch screen type mobile phone, the mobile phone may also monitor a sliding state of the touch screen, and when a user triggers a sliding operation on the screen, the mobile phone obtains a data acquisition instruction through the identified sliding track and sends the instruction to the PC.

Besides the sliding operation, the mobile phone also allows a user to perform long-press, double-click, multi-finger and other operations on the touch screen to trigger a data acquisition instruction. Similar to the previous embodiment, the cellular phone allows the user to set a specific touch operation.

In another embodiment of the present invention, the mobile phone may also monitor a built-in or external microphone, and when receiving a preset voice command sent by a user, the mobile phone obtains the data acquisition command and sends the command to the PC.

The preset voice command can be set by the user according to the preference of the user, and for example, the user can set the voice command to be "transmission", "start", and the like.

In another embodiment of the present invention, the mobile phone can also monitor a built-in light sensor, and a light sensor is generally disposed on the front side of the mobile phone near the handset for detecting the intensity of the ambient light outside the mobile phone to adjust the screen brightness. In this embodiment, the mobile phone may recognize the operation gesture of the user by using the light sensor, and when the user slides across the screen of the mobile phone with a palm or covers the screen of the mobile phone, the mobile phone recognizes that the external light intensity is smaller than the preset brightness threshold, thereby obtaining a data acquisition instruction, and sends the instruction to the PC.

It should be noted that, in practical applications, most users are used to configure a protective cover for a mobile phone, and when a cover of the protective cover covers a screen of the mobile phone, the external light intensity of the mobile phone can be reduced, so that misoperation is easily caused. In order to avoid the influence of the defect on the implementation of this embodiment, some operation discrimination mechanisms may be further preset for the mobile phone, for example, an interval lower limit is set for a brightness threshold, the lower limit brightness value is greater than 0, and when the mobile phone is covered by the protective case, the external light intensity falls outside the range of the threshold interval (usually, the external light intensity is 0 or close to 0), so that the operation gesture of the user may be discriminated.

306. And the PC searches the currently running equipment end application according to the data acquisition instruction.

307. And the PC sends the application identifier of the equipment end application to the mobile phone.

The application identifier carries an identity identifier of the device side application.

308. The mobile phone starts the mobile terminal application corresponding to the application identifier.

As a refinement of the embodiment of the present invention, to ensure that the user can use the application program on the mobile phone, when the installation package of the mobile application is not downloaded in the mobile phone, the mobile phone can automatically download and install the installation package in the background.

Specifically, the mobile phone background establishes a data downloading process, calls a data request interface, sends a data request to the network side server, and carries the application identifier in the request. After receiving the data request, the network side server searches and downloads a Uniform Resource Locator (URL) address of the application program according to the application identifier, and sends the URL address to the mobile phone. And the mobile phone recalls the data request interface to request downloading of the installation package according to the received URL address.

Further, with reference to the method shown in fig. 3, an embodiment of the present invention further provides a data obtaining method, where in the method, the mobile phone obtains the user data of the application program in the PC in addition to the application program in the PC, and synchronizes the user data of the application program itself according to the user data. Specifically, before step 3098 is executed, the PC obtains first user data of the device side application and sends the data to the mobile phone, where the first user data is the latest user data of the device side application. After receiving the first user data sent by the PC, the mobile phone updates the user data in the local mobile terminal application according to the first user data.

In one application scenario of this embodiment, a user plays an application game on a PC and upgrades the game character to level 14. When the mobile phone is transferred to the mobile phone to play a game, the mobile phone can acquire the user data of the device side application on the PC, and update the user data of the local mobile side application to the 14 th level according to the user data, so that the user does not need to start playing the game again from the 1 st level.

In an application scenario of this embodiment, when a certain social application program on a PC is transferred to a mobile phone for use, the mobile phone receives the latest user data of the PC, updates the user data of the mobile terminal application, and synchronizes user personal data (logs, photos), friend relationship chains, and other data to a local application for use by the user.

Further, in this embodiment, when the user ends the mobile terminal application at the mobile terminal, the mobile terminal generates new user data compared with the PC terminal, so that the mobile phone can also send the data to the PC to synchronize the user data applied at the device terminal, thereby facilitating the user to continue to use the device terminal application at the PC terminal subsequently. Specifically, after the mobile terminal application is ended, the mobile phone sends second user data to the PC, where the second user data is the latest user data generated when the mobile terminal application is ended. And the PC receives the second user data and updates the first user data applied by the local equipment terminal according to the data.

Taking the first application scenario as an example, a user plays a game at a mobile phone end, the game role is upgraded to the 16 th level when the game is finished, and after the application of the mobile end is closed, the mobile phone background automatically acquires the local latest second user data and sends the local latest second user data to the PC. After receiving the second user data, the PC updates the user data locally corresponding to the 14 th level to the 16 th level.

In addition, the data acquisition method provided by this embodiment may further synchronize user data based on the synchronization application. Currently, most social and game applications generate user data for individuals, and the user data changes along with the use of the applications by users, so that the problem of user data synchronization needs to be considered when the applications are used in a cross-device manner, otherwise, the normal use of the users is greatly influenced.
