As well understood by those skilled in the art, the above-mentioned electronic devices are exemplary only and not to be considered as a limitation of this present disclosure.
FIG. 1 is a flow diagram illustrating a method for processing a missed call in accordance with various embodiments of the present disclosure. This method may be implemented at an electronic device.
Referring to FIG. 1, at operation 110, the electronic device may check a connection of an incoming call. For example, the electronic device may receive an incoming call from another electronic device through a communication network. The received incoming call may be displayed on a screen of the electronic device. When a user sees the screen and desires to receive a call, a connection of the incoming call may be established. However, in case the user fails to see the screen or does not desire to receive the call, no connection may be made.
At operation 120, the electronic device may determine whether an incoming call is connected or not. If the incoming call is connected, a process is ended since there is no need to maintain a call notification.
If the incoming call is not connected, the electronic device may detect the termination of the incoming call at operation 130.
At operation 140, the electronic device may determine whether the incoming call is terminated without connection.
If the incoming call is terminated (namely, in case the incoming call is recognized as a missed call), the electronic device maintains a call notification in the same form as used when the incoming call is received at operation 150. Here, the form of a call notification refers to displaying an indication of an incoming call on a screen of the electronic device and outputting at least one of a ringtone, a vibration, and a mute sound.
According to some embodiments, a method for processing a missed call at an electronic device includes checking whether an incoming call received through a communication network is connected, detecting, if the incoming call is not connected, whether the incoming call is terminated, and maintaining, if the incoming call is terminated, a call notification in the same form as used when the incoming call is received.
The maintaining of the call notification may include displaying, on a display module, the same call notification screen as displayed when the incoming call is received.
The displaying may include displaying one or more call notification screens when one or more of the incoming calls are received.
The displaying may include displaying, based on a setting of the electronic device, the call notification screen associated with at least one of a selected number of incoming calls, recent incoming calls, and specific numbers of incoming calls selected from the recent incoming calls.
The displaying may include, if an actual call is connected through the communication network while the call notification screen for a missed call is displayed, distinctively displaying both a call notification screen for the actual call and the call notification screen for the missed call.
The maintaining of the call notification may include outputting, based on a setting of the electronic device, at least one of a ringtone, a vibration, and a mute sound which is the same output as used when the incoming call is received.
The outputting may include outputting light through an illumination unit in case of the mute sound.
The outputting may include obtaining an angle or motion of the electronic device using a sensor, and outputting, based on the obtained angle or motion, at least one of the ringtone, the vibration, and the mute sound.
The outputting may include detecting an ambient noise level of the electronic device using a sensor, and outputting, based on the detected noise level, at least one of the ringtone, the vibration, and the mute sound.
The maintaining may include maintaining, based on setting of the electronic device, the call notification associated with the incoming call from at least one of all phone numbers, stored phone numbers, selected phone numbers, blocked phone numbers, and non-blocked phone numbers.
The maintaining may include maintaining, based on setting of the electronic device, the call notification at least one of in a selected time zone, at every time except a specific time zone, and at all times.
The maintaining may include maintaining the call notification associated with the incoming call from a selected phone number received in a selected time zone.
The method may further include setting a notification interval associated with the call notification or a type of a ringtone.
The method may further include, when a call button displayed with the call notification is selected, trying to connect a call with a phone number of the incoming call.
The trying to connect the call may include notifying that a call connection will incur a call charge.
FIG. 2 is a screenshot illustrating an example of maintaining a call notification in accordance with various embodiments of the present disclosure.
Referring to FIG. 2, when an incoming call is received, the electronic device may notify that the incoming call is received by displaying a phone number of the incoming call (e.g., 010-1234-5678) on a call notification screen as shown in a screenshot 210 and by outputting an associated ringtone. If any image associated with the incoming call has already been stored in the electronic device, the screen may further display thereon the stored image. Normally, for a given time (e.g., for seventy seconds), the call notification screen is displayed and the ringtone is outputted. If the incoming call is not connected, an indication of a missed call is typically displayed on wallpaper or in a call log list. In this typical case, a user may fail to recognize a missed call until he or she sees the wallpaper or opens the call log list.
However, as shown in a screenshot 220, the electronic device of the present disclosure may display, through the display module, a call notification screen which is the same screen that is displayed when the incoming call is received. At this time, the electronic device may display a snooze call indication 220a for indicating a missed call together with a voice call indication 220b so that the call notification screen can be distinguished from an actual call notification screen.
According to various embodiments of the present disclosure, depending on a user's setting, the electronic device may determine whether to use “a snooze call service” for displaying a call notification screen.
According to various embodiments of the present disclosure, the electronic device may receive a user's input for setting at least one of the number of call notification screens to be displayed, target phone numbers for a call notification, and an available time zone for a call notification. Alternatively or additionally, the electronic device may have default values of the above setting items.
FIG. 3 is a screenshot illustrating an example of setting a call notification in accordance with various embodiments of the present disclosure.
Referring to FIG. 3, a screenshot 310 illustrates an example of setting the number of call notification screens to be displayed. For example, in case one or more incoming calls are received, the electronic device may display only one call notification screen, predetermined numbers of call notification screens, or call notification screens contained in recent incoming calls. In an embodiment, the electronic device may display a selected number of call notification screens (e.g., one, two, etc.), call notification screens of recent incoming calls, or call notification screens selected from recent incoming calls. Here, recent incoming calls may be missed calls that occur for a given time (e.g., one hour, three hours, six hours, etc.) set by a user or set as a default value by the electronic device. In case there are five or more recent incoming calls, only a selected number of calls (e.g., two or three calls) may become a target for a call notification.
A screenshot 320 illustrates an example of setting target phone numbers for displaying a call notification screen. For example, the electronic device may set a call notification screen to be displayed with regard to incoming calls from at least one of all numbers, specific numbers stored in a phonebook, selected numbers, and blocked numbers (or alternatively non-blocked numbers). Target phone numbers may be set by a user or set as a default value by the electronic device.
A screenshot 330 illustrates an example of setting an available time zone for displaying a call notification screen. For example, the electronic device may set a call notification screen to be displayed at least one of in a selected time zone, at every time except a specific time zone, and at all times. Such a time zone may be set by a user or set as a default value by the electronic device. Additionally, the electronic device may set a notification interval for displaying a call notification screen.
In some embodiments, the electronic device may set a call notification to be maintained with regard to an incoming call from a selected phone number received in a selected time zone.
FIGS. 4A and 4B are screenshots illustrating examples of displaying a call notification screen in accordance with various embodiments of the present disclosure.
Referring to FIG. 4A, a screenshot 410 illustrates an example of displaying one or more call notification screens when one or more incoming calls are received. As shown, in case of two incoming calls, the electronic device may display separately the first call notification screen 410a indicating one incoming call (e.g., received from “010-1234-5678”) and the second call notification screen 410b indicating another incoming call (e.g., received from “010-9999-8888”).
A screenshot 420 illustrates an example of displaying call notification screens associated with recent incoming calls in the order of time. As shown, in case the number of recent incoming calls is three, the electronic device may display the first call notification screen 420a of the most recent incoming call (e.g., received from “010-1234-5678” at 6:25 p.m.), the second call notification screen 420b of the next recent incoming call (e.g., received from “010-9999-8888” at 5:48 p.m.), and the third call notification screen 420c of the further next recent incoming call (e.g., received from “010-2580-1234” at 3:00 p.m.).
Referring to FIG. 4B, if a call is actually connected through a communication network during a display of a call notification screen, the electronic device may display distinctively both an actual call notification screen and the existing call notification screen as shown in a screenshot 430 or 440. For example, the screenshot 430 illustrates one example in which an actual call notification screen 430a is displayed at an upper portion and a call notification screen 430b associated with a missed call is displayed at a lower portion. Further, the actual call notification screen 430a may display thereon “actual call”, and the call notification screen 430b may display thereon “snooze call” associated with a missed call.
Additionally, the electronic device may selectively display graphical effects or highlights to an actual call notification screen 440a. For example, a screenshot 440 illustrates one example in which the actual call notification screen 430a is displayed to flicker and a call notification screen 440b of a missed call is displayed without any graphical effect.
In some embodiments, the electronic device may output at least one of a ringtone, a vibration, and a mute sound in the same form as outputted when an incoming call is received.
FIG. 5 is a screenshot illustrating an example of setting a call notification output in accordance with various embodiments of the present disclosure.
Referring to FIG. 5, a screenshot 510 illustrates an example of setting an output sound to be used when a call notification is maintained. As shown, this output sound may be set to at least one of a ringtone, a vibration, a mute sound, and a combination of ringtone and vibration. The output sound may be set by a user or set as a default value by the electronic device. In case the output sound is a mute sound, the electronic device may output light through an illumination unit. Therefore, the electronic device may not only visually display a call notification on the screen, but also output a call notification by means of at least one of sound, vibration and light. In case of sound, the electronic device may allow a user to set types of ringtone.
A screenshot 520 illustrates an example of setting an additional sensor function in connection with an output sound to be used when a call notification is maintained. Whether to use an output sound based on sensor values may be set by a user or set as a default value by the electronic device. For example, the electronic device may obtain an angle of the electronic device using a sensor and, based on the obtained angle, may output at least one of a ringtone, a vibration and a mute sound. Similarly, the electronic device may detect an ambient noise level of the electronic device using a sensor and, based on the detected noise level, may output at least one of a ringtone, a vibration and a mute sound.
FIGS. 6A and 6B are views illustrating examples of outputting a call notification in accordance with various embodiments of the present disclosure.
Referring to FIG. 6A, a reference numeral 610 illustrates an example of outputting a vibration when an electronic device is maintained level within a given range from a horizontal plane. For example, it may be assumed that the electronic device is placed on a desk or floor. In this case, since an angle obtained from a sensor falls within a given range from a horizontal plane, the electronic device may be regarded as being in a horizontal position. Further, judging that a user does not hold the electronic device, the electronic device may output a vibration rather than a sound.
A reference numeral 620 illustrates an example of outputting at least one of a ringtone, a vibration, a combination of ringtone and vibration, and a mute sound with light when an angle obtained from a sensor is not level or when any motion is detected. For example, if the electronic device is not in a horizontal position or if any motion is detected, it may be determined that a user holds the electronic device. Then the electronic device may output a ringtone or a combination of ringtone and vibration.
Referring to FIG. 6B, a reference numeral 630 illustrates an example of detecting an ambient noise level of an electronic device using a sensor and then outputting at least one of a ringtone, a vibration and a mute sound according to the detected noise level. For example, when a user having the electronic device walks along the street, he or she may often fail to hear a ringtone due to a high ambient noise level. In this case, the electronic device may output a call notification with tactile feedback such as a vibration, a combination of ringtone and vibration, and a combination of light and vibration.
FIG. 7 is a screenshot illustrating an example of connecting a call through a call notification screen in accordance with various embodiments of the present disclosure.
Referring to FIG. 7, as shown in a screenshot 710, a call notification screen displayed on the electronic device may contain a call button and an end button as if an actual call is received. When the call button is selected on the call notification screen, the electronic device may try to connect a call with a phone number (e.g., 010-1234-5678) of a missed call as shown in a screenshot 730. Optionally, as shown in a screenshot 720, it may be notified that a call connection will incur a call charge. In this case, a call connection as shown in a screenshot 730 may be tried when a user selects the OK button on a screenshot 720. Meanwhile, when the end button is selected on the call notification screen, the electronic device may regard it as call-blocking and process it as a normal missed call as shown in a screenshot 740. Then the electronic device may not display a call notification screen with regard to the blocked number.
FIG. 8 is a block diagram illustrating a network environment including an electronic device according to an embodiment of the present disclosure.
Referring to FIG. 8, the electronic device 801 may include a bus 810, a processor 820, a memory 830, an input/output interface 840, a display 850, a communication interface 860, and an sensor 870.

The device management application may manage (for example, install, delete, or update), for example, at least some functions of the external electronic device (for example, the electronic device 804) communicating with the electronic device 801 (for example, turning on/off the external electronic device itself (or some elements thereof) or adjusting brightness (or resolution) of a display), applications operating in the external electronic device, or services provided from the external electronic device (for example, a telephone call service or a message service).
According to various embodiments, the applications 834 may include an application designated depending upon an attribute (for example, a type) of the external electronic device (for example, the electronic device 804). For example, in a case where the external electronic device is an MP3 player, the applications 834 may include an application related to the reproduction of music. Similarly, in a case where the external electronic device is a mobile medical appliance, the applications 834 may include an application related to health care. According to an embodiment, the applications 834 may include at least one of an application designated to the electronic device 801 and an application received from the external electronic device (for example, a server 806 or the electronic device 804).
The input/output interface 840 may transfer instructions or data, input from a user through an input/output device (for example, a sensor, a keyboard, or a touch screen), to the processor 820, the memory 830, the communication interface 860, or the sensor 870 through, for example, the bus 810. For example, the input/output interface 840 may provide, to the processor 820, data for a user's touch input through the touch screen. Furthermore, through the input/output device (for example, a speaker or a display), the input/output interface 840 may output instructions or data received from the processor 820, the memory 830, the communication interface 860, or the sensor 870 through the bus 810. For example, the input/output interface 840 may output voice data, processed through the processor 820, to a user through a speaker.
The display 850 may display various types of information (for example, multimedia data or text data) to a user.
The communication interface 860 may connect communication between the electronic device 801 and the external electronic device (for example, the electronic device 804 or the server 806). For example, the communication interface 860 may be connected to a network 862 through wireless or wired communication to communicate with the external device. The wireless communication may include at least one of, for example, Wi-Fi, Bluetooth (BT), Near Field Communication (NFC), Global Positioning System (GPS) and cellular communication (for example, Long Term Evolution (LTE), LTE-A, Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunication System (UMTS), Wireless Broadband (WiBro), Global System for Mobile communication (GSM), and the like). The wired communication may include at least one of, for example, a Universal Serial Bus (USB), a High Definition Multimedia Interface (HDMI), Recommended Standard 1032 (RS-1032), and a Plain Old Telephone Service (POTS).

The communication network may include at least one of a computer network, the Internet, the Internet of things, and a telephone network. According to an embodiment, a protocol (for example, a transport layer protocol, data link layer protocol, or a physical layer protocol) for communication between the electronic device 801 and the external device may be supported by at least one of the applications 834, the application programming interface 833, the middleware 832, the kernel 831, and the communication interface 860.
The sensor 870 may process at least some pieces of information acquired from the other elements (for example, the processor 820, the memory 830, the input/output interface 840, and the communication interface 860), and may provide the processed information to a user through various methods. For example, the sensor 870 may recognize information on connection components included in the electronic device 801, store the information on the connection components in the memory 830, and execute the applications 834 based on the information on the connection components.
FIG. 9 is a block diagram illustrating an electronic device in accordance with various embodiments of the present disclosure.
Referring to FIG. 9, the electronic device 900 may include, but is not limited to, a control module 910, a display module 920, an output module 930, a sensor 940, and a communication module 950.
The communication module 950 receives an incoming call through a communication network. The communication module 950 performs a voice call, a video call, or a data communication with any external device through a network under the control of the control module 910. The communication module 950 includes therein a radio frequency (RF) transmitter to up-convert the frequency of an outgoing signal and to amplify the up-converted signal, and an RF receiver to low-noise-amplify an incoming signal and to down-convert the frequency of the amplified signal.
