1. Technical Field
The present disclosure relates generally to an electronic device and a method of connecting electronic devices.
2. Description of the Related Art
With recent advances in electronics and communications, consumers carry and use various electronic devices for a multitude of purposes. For example, users may prefer to use smart home appliances such as personal computers and/or a smart TV at home, and portable terminals such as smart phones outdoors.
Since the electronic devices employed by users are allocated to tasks based on time/place, a technology that supports the continuity of tasks performed by the user has become advantageous. For example, if the user can continuously perform a task involving media contents editing begun with a portable terminal outdoors, and switch the task over to a personal computer when moving indoors, the user can more conveniently complete the task. Furthermore, if the user synchronizes the portable terminal and the personal computer to connect the tasks performed through the portable terminal and the personal computer, the user can continuously perform the previously conducted task and conveniently complete the task through the two separate devices.
In order to continuously perform or share a task through a connection between electronic devices, each of the electronic devices should execute a suitable application to perform the task. For example, a task connection between applications for continuing a media editing task is made when each of the devices executes a media editing application in a connection state between the devices.
In this case, a user's control (via input commands) to allow the electronic device to execute the corresponding application is required in conventional methods and the device memory is burdened since the electronic devices should execute the corresponding applications. Furthermore, a user's control is needed conventionally whenever the connection and disconnection between the electronic devices is repeatedly made, and accordingly, the conventional task connection between applications may become onerous.
In accordance with an aspect of the present disclosure, an electronic device capable of performing a task connection with an external device is provided. The electronic device includes a display for displaying an execution screen of a first application; a communication interface configured to support a network connection with the external device; and at least one processor. The at least one processor is configured to control an operation of: while the connection with the external device through the communication interface is recognized during execution of the first application, transmitting a command including an ID of an application corresponding to the first application to the external electronic device through the communication interface. This ID transmission may facilitate the task connection between the two devices.
In accordance with another aspect of the present disclosure, an electronic device is provided. The electronic device includes: a display for displaying an execution screen of an application; a communication interface for supporting a network connection with a an external device; and at least one processor configured to control an operation of: while the connection with the external device is made through the communication interface, receiving a command including an ID of an application from the external device and executing an application mapped to the received ID in response to the command.
In accordance with another aspect of the present disclosure, a method of connecting electronic devices to realize a task connection is provided. A first application is executed by a first electronic device. The first electronic device is connected to a second electronic device through a communication interface during execution of the first application. While the first and second devices are connected, the first device transmits a command including an ID of an application corresponding to the first application to the second electronic device. The second device executes a second application mapped to the ID in response to the command.
A method of connecting electronic devices according to at least some embodiments can achieve a task connection between electronic devices without any user's control when one electronic device executes an application and then becomes connected to another electronic device.
A method of connecting electronic devices according to at least some embodiments can allow one electronic device to automatically execute an application corresponding to an application executed in another electronic device according to a user's selection.
An electronic device that does not support a call network, for example, a 3G and/or LTE network, according to some embodiments, can receive call forwarding from an electronic device supporting the call network and implement a call connection.

The bus 110 may be a circuit interconnecting the aforementioned components and transmitting communication information (e.g., a control message or data) between the aforementioned components.
The processor 120, for example, may receive instructions from the aforementioned components (e.g., the memory 130, the input/output interface 140, the display 150, the communication interface 160, and the application control module 170) other than the processor 120 through the bus 110, decode the received instructions, and perform operations or data processing according to the decoded instructions.
The memory 130 may store instructions or data received from or generated by the processor 120 or other components (e.g., the input/output interface 140, the display 150, the communication interface 160, and the application control module 170). The memory 130 may include programming modules, for example, a kernel 131, middleware 132, an application programming interface (API) 133, and applications 134.

The kernel 131 may control or manage system resources (e.g., the bus 110, the processor 120, and the memory 130) used to execute operations or functions implemented in the remaining other programming modules, for example, the middleware 132, the API 133, and the applications 134. Further, the kernel 131 may provide an interface that allows the middleware 132, the API 133, or the applications 134 to access and control or manage individual components of the electronic device 101.
The middleware 132 may serve to mediate between the API 133 or the applications 134 and the kernel 131, that is, allow the API 133 or the application 134 to communicate and exchange data with the kernel 131. Further, the middleware 132 may perform control (e.g., scheduling or load balancing) for task requests received from the applications 134 by using, for example, a method of assigning a priority for use of the system resource (e.g., the bus 110, the processor 120, or the memory 130) of the electronic device 101 to at least one of the applications 134.
The API 133 is an interface for allowing the applications 134 to control functions provided by the kernel 131 and the middleware 132, and may include at least one interface or function (e.g., instruction) for, for example, file control, window control, image processing, or text control.
According to various embodiments, the applications 134 may include an SMS/MMS application, an e-mail application, a calendar application, an alarm application, a health care application (e.g., an application for measuring the amount of exercise or blood glucose), and an environmental information application (e.g., an application for providing atmospheric pressure information, humidity information, temperature information, and the like). Additionally or alternatively, the applications 134 may include an application associated with information exchange between the electronic device 101 and an external electronic device (e.g., the electronic device 104). The application associated with information exchange, for example, may include a notification relay application for transferring specific information to the external electronic device or a device management application for managing the external electronic device.
For example, the notification relay application may include a function of transferring notification information, generated in another application of the electronic device 101 (e.g., the SMS/MMS application, the e-mail application, the health care application, or the environmental information application), to an external electronic device (e.g., the electronic device 104). Additionally or alternatively, the notification relay application, for example, may receive notification information from an external electronic device (e.g., the electronic device 104) and provide the received notification information to a user. The device management application, for example, may manage (e.g., install, remove, or update) a function for at least a part of an external electronic device (e.g., the electronic device 104) communicating with the electronic device 101 (e.g., a function of turning on/off an external electronic device itself (or some components thereof) or adjusting the brightness (or resolution) of a display), an application running on the external electronic device, or a service provided in the external electronic device (e.g., a calling or messaging service).
According to various embodiments, the applications 134 may include an application specified according to the attribute (e.g., type) of an external electronic device (e.g., the electronic device 104). For example, when the external electronic device is an MP3 player, the applications 134 may include an application associated with music playback. Similarly, when the external electronic device is a mobile medical device, the applications 134 may include an application associated with health care. According to an embodiment, the applications 134 may include at least one of an application assigned to the electronic device 101 and an application received from an external electronic device (e.g., the server 106 or the electronic device 104).

For example, the input/output interface 140 may provide the processor 120 with data corresponding to a user's touch input through a touch screen. Further, the input/output interface 140 may, for example, receive instructions or data from the processor 120, the memory 130, the communication interface 160, or the application control module 170 through the bus 110 and output the received instructions or data through the input/output device (e.g., a speaker or a display). For example, the input/output interface 140 may output voice data processed by the processor 120 to a user through a speaker.
The display 150 may display various pieces of information (e.g., multimedia data or text data) to a user.
The communication interface 160 may establish communication between the electronic device 101 and an external electronic device (e.g., the electronic device 104 or the server 106).

The application control module 170 may process at least some pieces of information acquired from other components (e.g., the processor 120, the memory 130, the input/output interface 140, and the communication interface 160) and provide the processed information to a user in various ways. For example, the application control module 170 may recognize information on connection components provided in the electronic device 101, store the information on connection components in the memory 130, and execute the applications 130, based on the stored information on connection components. The application control module 170 comprises at least one processor.

The term “module” as used in the present disclosure, for example, may mean a unit including one of hardware, software, and firmware or any combination of two or more of them. The “module”, for example, may be interchangeable with the term “unit”, “logic”, “logical block”, “component”, or “circuit”. The “module” may be the smallest unit of an integrated component or a part thereof. The “module” may be the smallest unit that performs one or more functions or a part thereof. The “module” may be mechanically or electronically implemented. For example, the “module” according to the present disclosure may include at least one of an application-specific integrated circuit (ASIC) chip, a field-programmable gate arrays (FPGA), and a programmable-logic device for performing certain operations, which are now known or will be developed in the future.
Thereafter, a network connection may be established between the first electronic device 101 and the second electronic device 104 in step 320. For example, the user may physically connect the first electronic device 101 and the second electronic device 104 through a Universal Serial Bus (USB) interface while the first electronic device 101 executes the first application. In this case, wired communication may be made between the first electronic device 101 and the second electronic device 104. Alternatively, the network connection may be made wirelessly using one of the methods noted above (e.g., using a short range communication method such as Bluetooth, WiFi or NFC).
When the connection between the first electronic device 101 and the second electronic device 104 is made, the first electronic device 101 may generate a command including an identification (ID) of at least one application (discussed below) corresponding to the first application being executed and transmit the command to the second electronic device 104 in step 330. For example, the first electronic device 101 may insert the ID of the application corresponding to the first application into a message header and transmit the command to the second electronic device 104. An application “corresponding to” the first application being executed may be a predetermined application automatically selected, or an application selected by the user, which will be described below in detail. The number of applications corresponding to the first application may be one or more. For example, when the first application is a photo album application, the application corresponding to the first application may be at least one of a photo album application, a media editing application, and a contact application (e.g. phone book, telephony, email or messaging application). That is, the application corresponding to the first application may be the first application itself and/or another application related to the first application which may utilize data stored in association with the first application, or vice versa.
The second electronic device 104 may execute an application mapped to the ID included in the command in response to the command received from the first electronic device (step 340). This executed application will be referred to as a “mapped application” or “second application”. (For simplicity of explanation, the following description will refer to one mapped application, but it is understood that plural mapped applications may be executed when plural respective IDs are received.) That is, the second electronic device 104 may automatically execute the second application following a connection with the first electronic device 101, without an additional user input command. For example, when the first application being executed is a photo album application, the second application may be a photo album application, a media editing application, or a contact application that is mapped to the ID. Since the command may include IDs of a plurality of applications, the second electronic device 104 may in this case execute a plurality of second applications mapped to the IDs.
Thereafter, the second electronic device 104 may transmit an application execution notification to the first electronic device 101 (step 350). The first electronic device 101, having received the application execution notification, may then transmit a task connection request to the second electronic device 104 (step 360). In response, the second electronic device 104 may transmit a task connection response that approves the task connection to the first electronic device 101 (step 370).
When the first electronic device 101 receives the task connection response, a task performed by the first application executed in the first electronic device 101 and a task performed by the second application executed in the second electronic device 104 may become connected to each other (step 380). For example, when the first application is a photo album application and the second application is a media editing application, tasks of the two applications may be automatically connected to each other so that an image output from the photo album application of the first electronic device 101 can be edited by the media editing application of the second electronic device 104. Thus a user of the second device may perform media editing using photos stored in association with the photo album application of the first device in substantially the same manner as if the photos were stored on the second device.
The first electronic device 101 may maintain an idle state (step 401). Thereafter, the first electronic device 101 may execute a first application in response to a setting, external input, or user input (step 403). The user may perform various tasks through the first application being executed.
Thereafter, the first electronic device 101 may establish a network connection with the second electronic device 104 while the first application is executed (step 405). For example, the user may physically connect the second electronic device 101 to the first electronic device 101 through a Universal Serial Bus (USB) interface. In this case, wired communication may be made between the first electronic device 101 and the second electronic device 104. For a wireless connection, the user may select a second electronic device to be communicatively connected, via a prompt for a Bluetooth connection or the like upon discovery of the second device in proximity.
When a connection between the first electronic device 101 and the second electronic device 104 is made, there may be a request for outputting a list, including an application corresponding to the first application selectively (step 407). For example, the request may be set up automatically as part of a task connection program controlling the method. That is, the application(s) corresponding to the first application may be predetermined according to a setting or selected by the user.
When there is no request for outputting the list, the first electronic device 101 may generate a command including an ID of at least one application predetermined to correspond to the first application, and transmit the command to the second electronic device 104 (step 421). For example, the first electronic device 101 may insert the ID of the predetermined application(s) corresponding to the first application into a message header and transmit the command to the second electronic device 104.
When there is a request for outputting the list, the first electronic device 101 may output the list on a display in step 411, and receive an input for selecting at least one application from the list through an input/output interface (step 413). Thereafter, the first electronic device 101 may generate a command including an ID of at least one selected application and transmit the command to the second electronic device 104 (step 415). For example, the first electronic device 101 may insert the ID of at least one application selected from the list into the message header and transmit the command to the second electronic device 104.
Thereafter, the first electronic device 101 may determine whether an execution notification of an application mapped to the ID (“second application”, as noted above) is received from the second electronic device 104 (step 431). If the execution notification is not received, this may be due to the second electronic device 104 not having the application mapped to the ID; as a result, the task connection attempt between the electronic devices may end.
However, when the execution notification is received, the first electronic device 101 may transmit a task connection request to the second electronic device 104 (step 433). Thereafter, when the first electronic device 101 receives a task connection response from the second electronic device 104, the first electronic device 101 may connect a task performed by the first application and a task performed by the second application executed in the second electronic device 104 (step 435).
The second electronic device 104 may maintain an idle state (step 501). In an embodiment, the second electronic device 104 may execute a Multicast Transport Protocol (MTP) application program in the background in the idle state. Thereafter, the second electronic device 104 may establish a network connection with the first electronic device 101 (step 502). For example, the user may physically connect the first electronic device 101 to the second electronic device 104 through a Universal Serial Bus (USB) interface. In this case, wired communication may be performed between the first electronic device 101 and the second electronic device 104. Alternatively, a short range wireless communication connection is established.
When the first electronic device 101 is connected to the second electronic device 104, the second electronic device 104 may receive a command, including one or more IDs from the first electronic device 104 (step 503). (Hereafter, a single ID is described for simplicity of explanation, but it is understood that multiple IDs may be received and multiple second applications may be executed by the second device 104 in response.) The ID may be an ID of at least one application corresponding to the first application executed in the first electronic device 101. The ID may be included in a message header of the command.
The second electronic device 104 may search for at least one second application mapped to the ID in a database in step 505. For example, when the second electronic device 104 receives the command from the first electronic device 101, an MTP application program being executed in the background may search for at least one second application mapped to the ID included in the command. The MTP application program may search for the second application corresponding to the ID based on a program list pre-stored or transmitted from an external source. For example, the database including the program list may be stored in a memory.
In step 507, it may be identified whether or not there is at least one second application mapped to the ID. When there is no second application mapped to the ID, the second electronic device 104 may end the process since a task connection with the first electronic device 101 cannot be made. However, when there is at least one second application mapped to the ID, the second electronic device 104 may execute at least one second application (step 509). For example, the MTP application program may execute at least one second application that is found. Furthermore, the MTP application program may transmit an application execution notification to the first electronic device 101 (step 511). For example, the MTP application program may transmit the application execution notification in an MTP command type to the first electronic device 101.
Thereafter, when the second electronic device 104 receives a task connection request from the first electronic device 101 in step 513, the second electronic device 104 may transmit a task connection response to the first electronic device 101 to approve the task connection request (step 513).
When the task connection response is transmitted to the first electronic device 101, the task performed by at least one second application and the task performed by the first application executed in the first electronic device 101 may be connected, as described earlier.
With continuing reference to
In step 605, the master device or slave device may receive the call, in response to user selection of an icon or the like, or, the call may go unanswered when no user input is detected. When the call is not answered, the process ends.
When the master device receives the call, a call between the master device and an external device may be connected (step 611). At this point, the user may answer and handle the call through the master device. During the call connection through the master device, the user may be required or otherwise desire to switch the call connection to a call connection with the slave device. Accordingly, the user may determine whether to switch the call with the master device to the call with the slave device in step 613. For example, the master device may provide the user with a UI including a call switching function, and the user may select call switching through the UI. When the call switching determination is received from the user, a call switching module included in the master device may forward the call to the slave device.
If, at 605, the slave device answers the call by means of user input such as selecting an icon for answering the call, the slave device sends a message indicative of the user selection to the master device. In this case, the master device connects the call at 611 and switches the call to the slave device via call forwarding (steps 613 and 621).
The call forwarding may include voice data forwarding and screen data forwarding. For example, the master device may convert voice data received through a communication network into Voice over Internet Protocol (VoIP) data and transmit the VoIP data to the slave device. The slave device may convert voice signals of the user (received at a microphone of the slave device) to voice data, convert this voice data to VoIP data and transmit this data to the master device. The master device may transmit the VoIP data received from the slave device to an external device through the network. Furthermore, the master device may mirror the screen data of the master device onto the slave device through the network connection.
When call switching to the slave device is not performed, the master device may continuously maintain a call connection in step 615 and may end a call function in step 617 when a call end is received.
When the slave device receives a call in response to a call reception notification, the slave device may receive call forwarding from the master device in step 621. The call forwarding is the same as described above. According to the call forwarding, the call between the slave device and the external device may be connected in step 623. During the call connection through the slave device, the user may be required or otherwise desire to switch the call connection to a call connection with the master device. Accordingly, the user may determine whether to switch the call with the slave device to the call with the master device in step 625. For example, the slave device may provide the user with a UI including a call switching function, and the user may determine call switching through the UI. When the call switching determination is received from the user, a call switching module included in the slave device may forward the call to the master device.
The user may desire to continue using the slave device to handle the call (step 627). The call function and any call forwarding commands terminate at step 629 when the user or other party inputs a command to hang up.
