Description

TECHNICAL FIELD [0001] The present invention relates to an electronic device and a communication control method for the electronic device,

Various embodiments of the present disclosure are directed to electronic devices and methods of controlling data communication of electronic devices.

Various types of electronic devices are being developed by the development of technology. In addition, various types of electronic devices are basically equipped with a communication function capable of transmitting or receiving necessary data through a network.

As an example of an electronic device, a smart phone includes an application processor (AP) and a communication processor (CP) (also referred to as a modem). As the various user applications installed in the smart phone are driven, the frequency of use of packet data through the network is increasing. In addition, background data sync occurs periodically for use of applications requiring real-time usability such as SNS, Email, Cloud Service and the like among user applications.

2. Description of the Related Art Recently, as interest in wearable devices has increased, technologies for providing various services through wearable devices have been developed. The wearable device is a device that is dependent on or independent of a master device (e.g., a smart phone), and the user application may be somewhat limited as compared with a general smart phone. In addition, data requiring synchronization with the master device is not required to be real time as data such as a telephone log (call log, contact, photograph, etc.). Since the wearable device has less battery capacity than the master device, it can be more sensitive to current consumption.

Applications or modules installed in the electronic device periodically attempt to synchronize data even when the user is not using the electronic device. In an electronic device, an AP transmits packet data to a network via a CP, and consumes high current for transmission of packet data.

As an example of an electronic device, a smart phone may be provided with a user interface (UI) for use of mobile data. When mobile data is turned off in an electronic device, connection with the network (for example, PDP (Packet Data Protocol) connection) is interrupted, and the use of mobile data may be restricted. The mobile data off state may continue unless the user again sets mobile data on. Again, when the user selects mobile data on, a signal for connection to the network (e.g., a PDP connection) is generated, and signals and delays with such networks may be involved each time mobile data on / off is selected.

In the mobile on state, the data synchronization of individual applications is not controlled while the user is not using the electronic device, and the frequency and subject of data synchronization can be determined by individual applications. However, when there is an application that frequently tries to synchronize or tries to synchronize a large amount of data in the background, there is a problem that a high current is consumed even when the user does not use the electronic device.

Various embodiments of the present disclosure can provide an electronic device and a communication control method of an electronic device capable of preventing unnecessary current consumption of the electronic device by blocking transmission data during a waiting time when the user does not use the electronic device in the electronic device have.

A method of controlling data communication of an electronic device according to any one of the various embodiments of the present disclosure includes: establishing a connection for data transmission to a network; Determining whether the electronic device is used or not; Setting a data transmission interruption mode when the electronic device is judged to be in an unused state; And interrupting transmission of data while maintaining a connection for the data transmission.

An electronic device according to any one of the various embodiments of the present disclosure includes: a connection manager configured to establish a connection for data transmission to a network; A data transmission mode setting unit for determining whether the electronic device is used and setting a data transmission interruption mode if the electronic device is judged to be in an unused state; And a data transmission controller for interrupting transmission of data while maintaining a connection for the data transmission.

According to various embodiments of the present disclosure, it is possible to improve the dissipation current that occurs during a standby time without using an electronic device.

Also, according to various embodiments of the present disclosure, it is possible to receive messages such as SMS / MMS, WAP push, etc. by maintaining a TCP session during the waiting time.

Further, according to various embodiments of the present disclosure, when the use of the electronic device is resumed, it is possible to transmit data in the electronic device directly without connection delay and signal exchange with the network.

Further, according to various embodiments of the present disclosure, it is possible to perform batch control without having to control the use period of data for each application.

Additional information about the control module 170 is provided via FIG. 3, described below.

Hereinafter, the detailed configuration of the electronic device according to the embodiments of the present disclosure will be described in detail. Each of the detailed configurations of the electronic device described later may be embodied in at least one of the configurations described above with reference to FIG. 2, or may be implemented as a separate module. 2, the control module 270 is illustrated as a separate module from the application processor 220, but at least some of the functionality of the control module 270 may be implemented and included within the application processor 220 , The entire functionality of the control module 270 may be implemented within the application processor 220 or other processor (e.g., communication interface 260).

Figs. 3 to 5 are diagrams showing a configuration example of an electronic device according to the embodiment of the present disclosure. Fig. Referring to FIG. 3, the electronic device may include a control module 310 and a communication module 320. The control module 310 may include at least one of a connection management unit 311, a data transmission mode setting unit 312, and a data transmission control unit 313. [

The connection management unit 311 may perform a function of establishing a connection (for example, a PDP connection) for transmitting data from the electronic device to the network. The connection establishment method may be variously implemented according to the type of the communication network. In the following description, a PDP connection will be described as an example of a connection for data transmission to a network in order to facilitate understanding. However, the present invention is not limited to a connection PDP connection for data transmission according to embodiments of the present disclosure, and connection methods may be variously applied according to various types of networks. For example, in the case of a cellular network, a PDP connection procedure should be performed as described above for data transmission. In case of Wi-Fi communication, an IP may be allocated through a Dynamic Host Configuration Protocol (DHCP). Although the method is different according to the bearer to communicate, the IP address is previously allocated according to the communication method, so that data communication through the network can be performed.

For example, a PDP communication socket may be established between an AP and a CP to transmit data from an application processor (AP) to a network, and default gateway information may be provided for packet routing at the IP layer. A routing table including host destination information (e.g., DNS server information) may be provided.

The data transmission mode setting unit 312 may set a data transmission interruption mode (which may be referred to as a suspended mode, for example) when it is determined that the electronic device is not in use according to the embodiment of the present disclosure. Once the data transmission interruption mode is set, according to various embodiments of the present disclosure, only the transmission data can be blocked while maintaining the PDP connection with the network. Again, once the user resumes use of the electronic device, the data transfer interruption mode is released and the data transfer mode can be set to connection.

The method for determining whether the electronic device is unused can be variously implemented. For example, when the screen provided in the electronic device is switched to the OFF state (SCREEN OFF) and becomes the standby mode, it can be determined that the screen is in an unused state. For example, in various embodiments of the present disclosure, screen state information can be used to determine unintended data by the user, and while the screen is in the off state, the user can not trigger any action on the screen, The foreground data can not be generated. Therefore, while the screen is in the off state, the user can determine that the user is not using the electronic device. Once the screen is switched back on again, the data transmission interruption mode can be released according to the embodiment of the present disclosure.

 In addition, according to various embodiments of the present disclosure, the electronic device may be judged to be in an unused state when there is no input of the user for the set time or more in the electronic device. In addition to the above-mentioned methods, various methods that can determine that the user is not using the electronic device can be applied to the embodiments of the present disclosure.

In addition, according to various embodiments of the present disclosure, the data transmission mode setting unit 312 can set a data transmission mode in consideration of not only the usage state of the electronic device, but also the processes currently being executed. For example, even if the electronic device is judged to be in an unused state, the data transfer interruption mode may not be set when at least one predetermined processor is being executed.

For example, an allowed process list (330) is stored in the electronic device, and if the process included in the allowable process list is running, the data transfer interruption mode It may not be set. The permissible process list may be, for example, a process that must operate even while the screen is off, and may include processes such as music streaming. If the music streaming process is running, the user may not want the execution to be stopped even if the screen is turned off, so that the process can be implemented so as not to switch to the data transmission interruption mode by including the process in the allowable process list. The allowable process list 330 may include a process name and an ID.

The data transmission control unit 313 may allow or block the data requested to be transmitted according to the mode setting of the data transmission mode setting unit 312. [ For example, when the data transfer mode setting unit 312 sets the data transfer interruption mode according to the embodiment of the present disclosure, it is possible to control the data not to be transmitted even if there is a data transfer request from the application.

The method of controlling the data transmission may be variously implemented. For example, by deleting the default gateway information of the routing table 340 according to various embodiments of the present disclosure, it is possible to implement such that the data requested for transmission is not transmitted from the electronic device to the network. When the application requests data transmission, the data requested to be transmitted can be transmitted on the network after confirming the default gateway information of the routing table 340. Therefore, when the default gateway information is deleted, data can not be transmitted.

Hereinafter, with reference to Figs. 4 and 5, an example in which each function portion shown in Fig. 3 is implemented in each configuration of the electronic device will be described.

4, an electronic device may comprise an application 410, a control module 420, a socket API 430, a kernel 440, a shared memory 460, and a communication module 470. When the electronic device is booted, a PDP connection with the network is established, and the TCP / IP socket is connected through the socket API 430, thereby allowing the electronic device to transmit and receive data to / from the external device through the communication module 470 .

If the control module 420 sets the data transfer mode to the data transfer interruption mode (e.g., suspend mode) according to the embodiment of the present disclosure, the application 410 can be notified that the currently set mode is the data transfer interruption mode.

Also, according to the embodiment of the present disclosure, the control module 420 may delete the default gateway from the routing table 450 provided in the kernel 440 area. Even if the default gateway is deleted, it is possible to receive data through the communication module 470 because the PDP connection with the present network exists (e.g., the PDP session is connected).

In accordance with the embodiment of the present disclosure, when data is to be transmitted from each application 410 to the outside, the default gateway information of the routing table 450 is checked according to the data transmission request. Since the default gateway information is deleted by the control module 420, the data transmission is interrupted in the data transmission interruption mode. In this way, transmission of data to be transmitted can be blocked without disconnecting the data communication with the network, so that there is no delay in releasing and reconnecting the data communication connection with the network in order to block the data transmission.

5 shows a data flow when the data transmission interruption mode is released by the control module 520. [ Referring to FIG. 5, when the data transfer interruption mode is released, the application 510 can be notified that the data transfer interruption mode that has been set is released. For example, it can notify that the current data transmission mode is a connected mode.

In addition, the control module 520 re-adds the default gateway of the routing table 550 deleted in the data transmission abort mode to the kernel 550 so that data transmission can be resumed.

When the application 510 requests data transmission according to the addition of the default gateway, it can transmit data requested to be transmitted through the communication module 570 to the network with reference to the added default gateway.

For example, if the electronic device is a wearable device, the problem of current consumption may be sensitive due to the low capacity battery, and the frequency and time of background data synchronization may have a significant effect on current consumption. In addition, since the wearable device requires a large amount of data transmission or rarely uses an application requiring real-time synchronization, according to the embodiment of the present disclosure, as described above, the wearable device blocks transmission data during a standby time when the user does not use the electronic device, The current problem can be solved.

In addition, when the electronic device is a mobile terminal such as a smart phone, by providing a setting menu such as 'power saving' or 'standby mode mobile data use' separately from the basic menu related to mobile data usage, It is possible to implement data transmission blocking according to the embodiments of the present disclosure described above. For example, it is also possible to set the data transmission interruption mode according to the setting of the user. If the data transmission interruption mode is set, only the data transmitted while maintaining the PDP connection is blocked while the electronic device is not used . Accordingly, it is possible to block only data transmitted from the application processor to the communication module without a delay due to additional signal exchange with the network. And can be easily used by automatically releasing the set data transmission interruption mode when the user starts using the electronic device.

In FIG. 4 or 5, the control modules 420 and 520 may correspond to the processor 220 of FIG. 2 or at least some functions may be included in the processor 220 of FIG. In addition, as another implementation method, the control modules 420 and 520 may be additionally configured as separate modules (for example, the control module 270) in FIG. 4 or FIG. 5, the communication modules 470 and 570 may correspond to the communication interface 260 of FIG. 2, or at least some functions may be included in the communication interface 260 of FIG.

On the other hand, in the embodiments of the present disclosure described above, each functional unit and module may mean a functional or structural combination of hardware for carrying out the technical idea of the present disclosure or software for driving the hardware. For example, each functional unit may refer to a logical unit of a predetermined code and a hardware resource for executing the predetermined code, and may be a code physically connected to the functional unit, But can be easily deduced to the average expert in the field of embodiments of the disclosure.

An electronic device according to any one of the various embodiments of the present disclosure includes: a connection manager configured to establish a connection for data transmission to a network; A data transmission mode setting unit for determining whether the electronic device is used and setting a data transmission interruption mode if the electronic device is judged to be in an unused state; And a data transmission controller for interrupting transmission of data while maintaining a connection for the data transmission.

The data transmission mode setting unit may determine whether the electronic device is used in at least a screen on or off state of the electronic device.

The determination as to whether or not the electronic device is used may determine that the electronic device is in an unused state when the electronic device has not been input for a predetermined time or more.

Wherein the data transfer mode setting unit determines whether to execute at least one set process if the electronic device is in an unused state and sets a data transfer interruption mode if all processes are not being executed for the set at least one process Can be set.

The data transmission control unit can normally perform reception processing on data received while the data transmission interruption mode is set.

The connection management unit may delete the default gateway information from the routing table when the data transmission interruption mode is set.

When the data transfer interruption mode is set, the connection management unit can notify the application layer of the data transfer interruption mode status.

Wherein the data transmission mode setting unit determines whether the electronic device is used after the transmission of the data requested to be transmitted is blocked and releases the data transmission interruption mode when the electronic device is in use, The data transfer control unit may transmit the requested data to the external device when the data transfer is requested from at least one application.

The connection management unit may reset the default gateway information in the routing table when the data transmission interruption mode is canceled.

When the data transmission interruption mode is canceled, the connection management unit can notify the application layer of the data transfer interruption mode release state.

Hereinafter, a data communication control procedure of the electronic device according to the embodiment of the present disclosure will be described with reference to FIG.

6, an electronic device may establish a PDP connection with a network at operation 601 in accordance with an embodiment of the present disclosure. In FIG. 6, PDP connection setting is described, but network connection setting can be executed in various ways according to various network environments.

If a network connection is established, at operation 603, it is determined whether the electronic device is in use or in an unused state. As a result of the determination, if the electronic device is not in the unused state, the data transmission mode may be set as a connection in operation 613, and the default gateway of the routing table may be maintained as it is. If the default gateway of the routing table has been deleted due to the previously set data transmission interruption mode, at operation 615, a default gateway of the routing table may be added. In operation 611, the set mode information may be transmitted to an application or the like.

As a result of the determination in operation 603, if the electronic device is in an unused state, operation 605 can determine whether at least one permitted process is being executed.
