How to Share Data Between User Terminals and Their Applications

The present invention relates to a method of sharing data between a user terminal and an application thereof, and more particularly, to upload and download data to be shared between applications using a clipboard, and to upload and download data using a custom URL. By notifying the counterpart application, the present invention relates to a method of sharing data between a user terminal and its application, which enables sharing of data between applications without traffic.

Recently, due to the development of user terminals, various types of user terminals such as smart phones, tablet PCs, PDAs, or mobile communication terminals are used, and these user terminals are equipped with mobile operating systems. As a mobile dedicated operating system is mounted, various mobile dedicated applications developed to operate in a mobile dedicated operating system are installed and used in a user terminal.

In the iOS (iPhone OS) environment developed by Apple, each of these mobile operating systems operates independently of each other, and data sharing among each application is strictly limited. As a result, it was not possible to share data among a plurality of applications downloaded and installed from different servers.

However, if the data cannot be shared among the applications in this way, even if the same data is required in a plurality of applications, each application must obtain a data through a separate process, the application must perform an inefficient operation. In addition, since each application operates separately, the traffic of the user terminal may increase.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data sharing method between a user terminal and an application thereof, by enabling data sharing between a plurality of applications, which not only enables the application to operate efficiently but also reduces traffic of the user terminal.

The object may include uploading data to a clipboard to be shared by a first application installed in a user terminal to support an arbitrary service; Invoking a second application that is a counterpart application in the first application to notify that the data has been uploaded to the clipboard; Downloading the data from the clipboard to the second application; And notifying that the data has been downloaded from the second application to the first application.

The object includes a clipboard to which shared data is uploaded; And a plurality of applications provided from a server to provide any service, uploading data to the clipboard to share each other, and exchanging information that the data has been uploaded and downloaded. .

According to the present invention, by using the clipboard to share data between applications installed on an iOS-based user terminal, it is possible to reduce the traffic between the application and the server, and as the data is directly shared between applications, the latest data can be quickly updated. Can be obtained.

1 is a block diagram of a system including a user terminal having a data sharing function between applications according to the present invention.

In the system according to the present invention, a plurality of applications are installed and have a function of sharing data between applications, and the user terminal 1 can communicate with the user terminal 1 through the network 200 and is installed in the user terminal 1. It includes a plurality of service providing server 100 for providing an application.

A plurality of applications installed in the user terminal 1 may be downloaded and installed from different service providing servers 100, respectively, or may be provided by one service providing server 100 or a plurality of service providing servers operated by one company ( 100 may be downloaded and installed.

In the traditional iOS environment, data sharing between applications was strictly limited. In the present invention, the data is uploaded and downloaded by using the clipboard 5 so that data can be shared among a plurality of applications, and the data is uploaded or downloaded by calling each other between an application for uploading data and an application for downloading data. Notify me.

Meanwhile, in order to notify upload and download of data between applications, a Uniform Resource Locator (URL), for example, a Custom URL is used to call a counterpart application. The Custom URL defines the information of each application, and may be used as an internal address used by the application in the user terminal 1.

In the case of applications downloaded and installed from the same service providing server 100 or from a service providing server 100 of the same company, the custom URLs of each other are known in advance. However, applications downloaded and installed from the service providing server 100 of different companies do not know each other's Custom URL, so they should be obtained by inquiring the Custom URL of the other application to the server of the other application.

The user terminal 1 provided with such an application may be a personal digital assistant (PDA), a portable media player (PMP), a smart phone, a tablet PC, a personal digital assistant (PDA), a computer such as a mobile communication terminal, or the like.

When the user terminal 1 is a smart phone, a tablet PC, a PDA, or a mobile communication terminal, Apple (iOS), a mobile operating system may be installed by Apple, and thus, a terminal equipped with a mobile operating system. The service providing server 100 described above for communication with the mobile terminal may have compatibility with a mobile dedicated operating system.

The above-described smart phone, tablet PC, PDA, mobile communication terminal can be connected to the network 200 through a communication module such as a wired or wireless LAN (WiFi) or a mobile communication module.

In addition, as well as the user terminal 1, as shown in Figure 1, each service providing server 100 is also connected through the network 200. Here, the network 200 is a wired or wireless network 200, an access network to which the service providing server 100 is connected, and an access network to which the user terminal 1 is connected (for example, a mobile communication network and a wireless LAN (WiFi)). And the like, and a core network that may be in various forms for connecting such access networks.

Hereinafter, the user terminal 1 having a data sharing function between applications according to an embodiment of the present invention will be described in more detail.

FIG. 2 is a block diagram illustrating the configuration of the user terminal of FIG. 1.

The user terminal 1 according to the present invention may include a clipboard 5, a plurality of applications 10, and a terminal controller 20.

The clipboard 5 is generally a software program used to temporarily store data during use of the application 10 in the user terminal 1 and may be viewed as a temporary memory. The clipboard 5 provided in the user terminal 1 according to the present invention may be used to temporarily store data to be shared between the applications 10.

For example, four applications 10 for providing a sound source are installed in the user terminal 1, and the four applications 10 are developed from companies A, B, C, and D, respectively. It is downloaded from the server of each company and installed in the user terminal 1. Among them, the application developed by Company D provides a service that allows the user to play through the Company D application by sharing all the sound source files provided by the applications provided by Company A, Company B, Company C. In order to use the services provided by Company D's applications, data stored in Company A, Company B, and Company C must be shared with Company D's applications.

When you want to share the data of company A, company B, company C with company D application, company A company, company B company C uploads the data to the clipboard (5), and company D application sends the data to the clipboard. We download from (5).

The plurality of applications 10 may share data with each other, and notify the other party of data upload or download when data is shared. To this end, each application 10, the data selector 11, the data transfer unit 12, the notification unit 13, the storage unit 14, the validity determination unit 15, the address request unit 16, App control unit 17 may include.

The data selector 11 selects data to be shared, and the data selector 11 selects data to be shared according to preset selection criteria. In this case, the selection criterion may be determined according to whether the application 10 first shares data with another application and whether or not it is updated.

For example, in each of the data selection unit 11 provided in the Company A, Company B, and Company C, each of the sound source files stored in the Company A, Company B, and Company C to be transferred to the Company D application to share Select the sound source file. At this time, when transferring the sound source file from the company A, the company B, and the company C to the company D for the first time, the data selector 11 of the company A, the company B, the company C all the sound source files stored in each application By selecting, all existing sound source files can be delivered to the company D's application.

After all the existing sound source files are delivered to the D company application, the data selection unit 11 of the A company, the B company, and the C company application selects only the updated sound source files.

Meanwhile, the data selector 11 may select data to be uploaded to the clipboard 5 at predetermined time intervals according to a preset condition, or select updated data as data to be uploaded every time data is updated in the application. It may be.

That is, in the above example, the data selection unit 11 of the A company, B company, and C company application may select the updated sound source file each time the sound source file is updated in each application to be delivered to the D company application. In addition, it is possible to select a sound source file updated in the meantime every predetermined time to be delivered to the company D company.

The data transfer unit 12 may upload the data selected by the data selection unit 11 to the clipboard 5 or download the data uploaded to the clipboard 5. That is, the data transfer unit 12 of the application 10 to share data with another application 10 uploads the selected data to the clipboard 5 and receives data to be shared from the other application 10. The data transfer unit 12 of the application 10 downloads the data uploaded to the clipboard 5.

For example, the data delivery unit 12 of the company A, B, Company C application, uploads the sound source files selected by the data selection unit 11 to the clipboard 5, the data delivery of the company D application The unit 12 downloads the sound source files uploaded to the clipboard 5.

The notification unit 13 may notify the application 10 to share data of the information that the data has been uploaded, and notify the application 10 that has provided the data of the information that the data has been downloaded. The notification unit 13 calls the counterpart application 10 to notify whether data is uploaded or downloaded, and at this time, a custom URL can be used.

That is, the notification unit 13 of the application 10 that has uploaded the data notifies that the data to be shared is uploaded by calling the Custom URL of the counterpart application 10, and the notification unit of the application 10 which has downloaded the data. 13 may call the Custom URL of the counterpart application 10 to notify that data has been downloaded.

In addition, the notification unit 13 transmits its own Custom URL when it uploads and downloads data to the counterpart application 10. This can be used to determine the validity of the data.

For example, the notification unit 13 of the company A, B, C company application uploads the sound source files to the clipboard 5 in the data delivery unit 12, using the Custom URL of the company D application The company D application can be notified that the sound source files have been uploaded to the clipboard 5. On the contrary, when the notification unit 13 of the D company application downloads the sound source files uploaded to the clipboard 5 from the data transfer unit 12, the sound source file using the Custom URL of the A company, the B company, and the C company application is downloaded. Can be notified that they have been downloaded.

The storage unit 14 stores custom URLs exchanged between applications 10 to share data with each other. At this time, the Custom URL of each application 10 is stored in match with the basic information about the application 10. The basic information may include the name of the application 10, a distributor, a server address, and the like.

For example, the storage unit 14 of the D company application stores information such as a custom URL, a name, a distribution company, and a server address for each of the A company, the B company, and the C company application. On the contrary, the storage unit 14 of the A company, the B company, and the C company application may store a custom URL, a name, a distribution company, a server address, and the like of the D company application.

The validity determination unit 15 may determine the validity of data provided from another application 10. The validity judgment unit 15 compares the information including the Custom URL provided from the application 10 that provided the data with the information previously stored in the storage unit 14 for the corresponding application 10, and compares the data. Determine the validity.

That is, each application 10 is a custom URL, name, and the like provided from the application 10 that provided the data, and the corresponding application 10 stored in the storage unit 14 before downloading the data provided from the other application 10. By comparing the basic information matched to the Custom URL of, it is possible to determine whether the corresponding data is provided from the valid application 10.

For example, if the above company D application is notified that the sound source file has been uploaded from the company E application to the clipboard 5, the validity judgment unit 15 compares the custom URL of the company E application with the pre-stored custom URL. Can be seen. As a result of the comparison, when there is no Custom URL matching the Custom URL, the validity determination unit 15 of the Company D application determines that the data is not valid and does not download. If the company E application transmits one of the custom URLs pre-stored in the company D, for example, the Cusotm URL of the company A application, the basic information stored together with the custom URL of the company A application, and Since the information provided from the application does not match, it may be determined that the data is invalid.

The address requester 16 may be configured to provide information about the counterpart application 10 when the application 10 for sharing data is provided and installed from a server of a different company, that is, when the custom URL of the counterpart application 10 cannot be determined. In order to obtain the Csutom URL, the server of the counterpart application 10 may request a custom URL of the counterpart application 10.

The address request unit 16 of the application 10 to obtain the custom URL of the counterpart application 10 first transmits a command to obtain a custom URL of the counterpart application 10 to its server. Then, the server of the application 10 requests a custom URL of the application 10 to the server of the counterpart application 10. At this time, the server of the application 10 transmits the Custom URL and basic information of the application 10 to the server of the counterpart application 10. The server of the counterpart application 10 transmits the custom URL of the application 10 to the server of the corresponding application 10, and the server of the application 10 transmits the custom URL of the counterpart application 10 to its own application 10. To pass.

For example, when the company D wants to know the custom URL of the company A application, the address request unit 16 of the company D application requests the server of the company D to obtain the custom URL of the company A application. . The server of the company D transmits the custom URL and basic information of the company D application to the company A application server, and requests the custom URL and the basic information of the company A application. Then, the company A application server delivers the custom URL and basic information of the company A application to the company D application server, and the company D server transfers the information to the company D application.

The app controller 17 may convert the application 10 into an active state or an inactive state when downloading or uploading data using the clipboard 5.

The app control unit 17 of the application 10 for uploading data uploads the data to the clipboard 5 in the application 10 for uploading data, and calls the counterpart application 10 using the Cusotm URL to call the data. When notified of the upload, the application 10 for uploading data is switched to the inactive state. In addition, when notifying that the data has been downloaded from the counterpart application 10, the app control unit 17 of the application 10 for uploading data switches the application 10 for uploading data to an active state.

On the other hand, when notifying that the data has been uploaded to the clipboard 5, the app control unit 17 of the application 10 for downloading data switches the application 10 for downloading data to an activated state. Then, the validity judgment unit 15 of the application 10 for downloading data determines that the data is valid, the data transfer unit 12 downloads the data from the clipboard 5, and then the notification unit 13. When the application 10 that uploads the data is called in to notify that the download is completed, the app controller 17 switches the application 10 that downloads the data to an inactive state.

For example, the app control unit 17 of the B company application deactivates the B company application when it is notified that the music file of the B company application is uploaded to the clipboard 5 and the music file is uploaded to the D company application. Switch to Further, when notified that the music file has been downloaded from the company D application, the app control unit 17 of the company B application switches the company B application to the activated state.

On the other hand, when notified that the music file has been uploaded to the clipboard 5 from the company B application, the app control unit 17 of the company D turns the company D application into an active state. Then, when the music file is downloaded from the D company application and notified that the music file is downloaded to the B company application, the app control unit 17 of the D company application switches the D company application to an inactive state.

The terminal controller 20 may control operations of the components in the operation of the application 10 and control transmission and reception of information between the application 10 and the service providing server 100.

Meanwhile, in the above-described embodiment, the app controller 17 controls the activation and deactivation of the application 10, but the terminal controller 20 may control the activation and deactivation of the application 10. In this case, the terminal controller 20 may perform the functions of the above-described embodiment as it is.

That is, when the application 10 uploading data uploads the data to the clipboard 5 and calls the counterpart application 10 using the Cusotm URL to notify the upload of the data, the terminal controller 20 uploads the data. The application 10 is deactivated. In addition, when notified that data has been downloaded from the counterpart application 10, the terminal controller 20 switches the application 10 for uploading data to an active state.

On the other hand, when notified that the data has been uploaded to the clipboard 5, the terminal controller 20 switches the application 10 for downloading the data to the active state. Then, when the application 10 for downloading data downloads the data from the clipboard 5 and then notifies the application 10 for uploading data that the download is completed, the terminal controller 20 downloads the data. Switch the application 10 to inactive state.

The Custom URL of the application 102 is requested, and the server of the first application 101 transmits the Custom URL and basic information of the first application 101 to the server of the second application 102 and at the same time the second application ( Request Custom URL and basic information of 102) (S400).

The second application 102 server transmits the custom URL and basic information provided from the first application 101 server to the second application 102, and the second application 102 stores the custom URL and the basic information. 14) (S405).

The server of the second application 102 transmits the custom URL and basic information of the second application 102 to the first application 101 (S410), and the address request unit 16 of the first application 101 The custom URL and basic information of the two applications 102 are stored in the storage unit 14 (S415).

After the Custom URL and the basic information are exchanged between the first and

second applications

101 and 102 to share data, the first application 101 and the second application 102 use the clipboard 5 to exchange data. Can share.

In order to share data, the data selector 11 of the first application 101 selects data to be shared. In this case, when data sharing between the first application 101 and the second application 102 is the first time, the data selecting unit 11 of the first application 101 selects all data to be shared. If the first application 101 and the second application 102 have shared data, the data selector 11 selects data to be updated since the data is shared.

When the data to be shared is selected, the data transfer unit 12 uploads the selected data to the clipboard 5 (S420). Then, the notification unit 13 notifies that the data has been uploaded to the second application 102 using the Custom URL of the second application 102 stored in the storage unit 14 (S425). At this time, the app controller 17 or the terminal controller 20 switches the first application 101 to an inactive state.

The app control unit 17 or the terminal control unit 20 of the second application 102 that has received the notification changes the second application 102 to an active state. Then, the validity judgment unit 15 is operated to include information including a custom URL of the first application 101 stored in the storage unit 14 of the second application 102 and information provided from the first application 101. Compare the to determine the validity of the first application (101) (S430).

As a result of the determination, when the validity of the first application 101 is recognized, the data transfer unit 12 of the second application 102 downloads data from the clipboard 5 (S435). Then, the notification unit 13 calls the Custom URL of the first application 101 to notify that the download of the data is complete (S440). At this time, the app control unit 17 or the terminal control unit 20 of the second application 102 switches the second application 102 to an inactive state, and the app control unit 17 or the terminal control unit of the first application 101 ( 20 transitions the first application 101 to an active state.
