DESCRIPTION OF EMBODIMENTS
Hereinafter, a mobile communication terminal for receiving a call while a navigation service is running and a method for the same according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7.

    The detailed description primarily focuses on what is necessary for understanding the operation or actions according to the present invention. The same reference denotations in the drawings refer to the same elements throughout the specification. Further, when determined to make the gist of the present invention unnecessarily unclear in describing the present invention, the detailed description of the known functions or configurations is omitted.


At this time, according to the present invention, a new method is proposed which 1) displays a call reception window displaying call connection state information to be overlaid on the screen on which a navigation service is provided when an incoming call is received while the navigation service is in use in a mobile communication terminal, or 2) splits the screen on which the navigation service is provided to display a route guidance image on a split portion of the screen and the call connection state information on another split portion of the screen.
FIG. 1 is a view illustrating a mobile communication terminal for receiving a call during a navigation service according to an embodiment of the present invention.
As shown in FIG. 1, the mobile communication terminal for providing a navigation service according to the present invention may include a transmitting/receiving unit 110, an input unit 120, a navigation unit 130, a controller 140, an audio output unit 150, a display unit 160, and a memory 170.
Here, the mobile communication terminal is a device that may receive a mobile communication service using a mobile communication network may in concept include, e.g., a mobile phone, a smartphone, a laptop computer, or a PDA.
The transmitting/receiving unit 110 may transmit an outgoing call to an opposite party's mobile communication terminal or an incoming call from the opposite party's mobile communication terminal and may transmit and receive a voice according to a call connection.
The input unit 120 may be input with information as per the user's key or menu manipulation. The user may set, e.g., an incoming call receiving function to display information relating to an incoming call when the incoming call is received through the input unit 120 while the navigation service is in use.
The navigation unit 130 may support the navigation service. That is, the navigation unit 130 may receive location information from a GPS satellite and may provide driving information of a moving body, e.g., a vehicle, using the received location information and pre-stored map data.
The controller 140 may perform control to receive the driving information or the like from the navigation unit 130 and to output the received driving information or the like through the audio output unit 150 and the display unit 160. In particular, when an incoming call is received while the navigation service is in use, the controller 140 may provide call connection state information not to affect the navigation service.
As used herein, the call connection state Information may include the opposite party's phone number, the opposite party's name, and the call time.
The audio output unit 150 may output a route guidance voice in case the navigation service is in use and output the opposite party's voice in case the call is connected. At this time, the audio output unit 150 outputs the route guidance voice while the navigation service is in use, and if a call is connected, cuts off the output of the route guidance voice to output the opposite party's voice.
The display unit 160 may display a route guidance image in case the navigation service is in use. In particular, when an incoming call is received while the navigation service is running, the display unit 160 1) may display a call reception window providing call connection state information to be overlaid on a preset region in the route guidance image and 2) may split the display region to display the route guidance image on a first split region and the call connection state information on a second split region.
If the call reception window providing the call connection state information is displayed, the display unit 160 visually provides the navigation service through the route guidance image and aurally provides the call connection for the incoming call through a voice.
At this time, the display unit 160 may be a touchscreen that allows for manipulation on screen.
The memory 170 may store a phone number list, images or pictures, map data, etc.
FIG. 2 is a view illustrating a process of setting an incoming call receiving function according to an embodiment of the present invention.
As shown in FIG. 2, the mobile communication terminal according to the present invention sets the incoming call receiving function using, e.g., “T-map phone helper.”
1) In item {circle around (1)}, whether to use the T-map phone helper service may be set. That is, the T-map phone helper service is started or paused. If the T-map phone helper service is started, when a call is received during the route guidance, a call reception window is shown to be overlaid on the route guidance screen. If the T-map phone helper service is paused, when a call is received during the route guidance, a default call reception screen is displayed on the route guidance screen to cover the route guidance screen.
2) In item {circle around (2)}, whether to allow contact information to be always shown may be set. That is, this is a setting for the case where when a call is received, the phone number therefor is retained in the contact information. It is set whether to display, if a picture, along with the phone number, is retained in the contact information, the picture alone or together with the content of the contact information, on the call reception window overlaid on the route guidance screen.
3) In item {circle around (3)}, it may be set whether to display the caller's number that is not retained. That is, this is a setting for the case where when a call is received, the phone number therefor is not retained in the contact information. It is set whether to display the caller's number or a picture alone on the call reception window overlaid on the route guidance screen.
4) In item {circle around (4)}, an elapsed time to automatically disconnect call may be set. That is, if upon reception of a call, the call reception window overlaid on the route guidance screen is left unclicked, the T-map phone helper service automatically hangs up the call. The wait time from when the call is received to when the call is automatically disconnected is set. In other words, if the call reception window is not pressed for a set time after the call reception window is displayed overlaid on the route guidance screen, the T-map phone helper automatically disconnects the call.
For example, in case 0 sec (immediately disconnect) is set, the T-map phone helper does not display the call reception window on the route guidance screen when a call is received.
5) In item {circle around (5)}, a ring tone or vibration mode after the call reception window is displayed may be set. That is, it is set whether to sound off a ringtone when the call reception window is displayed overlaid on the route guidance screen.
6) In item {circle around (6)}, the volume of the speaker phone after call connection may be set. That is, when a call is received during the navigation service, the T-map phone helper automatically switches the phone to speaker phone mode or hands-free mode. At this time, it is set whether to automatically set the volume of the speaker phone to the maximum. In case ‘after call connection, maximize the speaker volume’ is set, the maximum volume applies upon call connection, and if the call is disconnected, it automatically turns back to the original volume.
FIG. 3 is a first view illustrating a method for receiving a call during a navigation service according to an embodiment of the present invention, and FIG. 4 is a first view illustrating the screen displaying a call connection state according to an embodiment of the present invention.
Referring to FIGS. 3 and 4, the mobile communication terminal according to the present invention, when a navigation service is activated, may display a route guidance image through the display unit (S310).
Next, the mobile communication terminal may identify whether an incoming call is received (S320).
Then, if the incoming call is resultantly identified to be received, the mobile communication terminal displays a call reception window representing call connection state information, e.g., the opposite party's phone number or name, on the route guidance screen as shown in FIG. 4(a), wherein the call reception window is displayed in a first color (S330) so that it may be identified whether the incoming call connection is selected (S340).
Thereafter, if the incoming call connection is identified to be selected, the mobile communication terminal connects a call as shown in FIG. 4(b) (S350) and changes the color of the call reception window to a second color to represent the call connection (S360).
That is, if the user presses the call reception window flickering in red, the mobile communication terminal connects the call—for example, automatically switches to hands-free mode, i.e., speaker phone mode to connect the call, and if the call is connected, the mobile communication terminal changes the color of the edge of the call reception window to green. The edge of the call reception window staying in green represents that the line is busy.
At this time, in case the received number is contained in the contact information, the content such as name or company name as well as the image or picture included in the contact information is displayed on the call reception window, and in case the received number is not contained in the contact information, the received phone number together with the preset image or picture is displayed.
In contrast, unless the incoming call connection is identified to be selected by the user, the mobile communication terminal sends a text message with preset content to the opposite party's mobile communication terminal that has sent the incoming call. For example, the mobile communication terminal may create a text message saying “Now I am driving so I cannot respond to this call” and send the text message to the opposite party's mobile communication terminal.
Next, the mobile communication terminal may identify whether the call connection is terminated (S370), if the call connection is terminated, remove the call reception window (S380), and display back only the route guidance screen. That is, if the call connection is terminated in the mobile communication terminal as the opposite party hangs up the phone, or the call reception window is pressed to disconnect the call, for example, the call reception window disappears from the route guidance image.
FIG. 5 is a view illustrating various types of call reception windows according to an embodiment of the present invention.
As shown in FIG. 5(a), according to an embodiment of the present invention, the color of the edge of the call reception window may be set so that the color of the edge when an incoming call is received is different from the color of the edge when the incoming call is connected. For example,
As shown in FIG. 5(b), the call reception window may be displayed to show a preset image or picture as its background image, may be displayed transparently so that the route guidance screen is shown without the preset image or picture, or may be displayed to show an image or picture corresponding to an incoming call.
The call reception window may adjust its transparency according to the user's selection as shown in FIG. 5(c). That is, the call reception window may be adjusted so that the window itself or its content is transparent or opaque through an adjusting bar.
FIG. 6 is a second view illustrating a method for receiving a call during a navigation service according to an embodiment of the present invention, and FIG. 7 is a second view illustrating the screen displaying a call connection state according to an embodiment of the present invention.
Referring to FIGS. 6 and 7, the mobile communication terminal according to the present invention, when a navigation service is activated, may display a route guidance image through the display unit (S610).
Next, the mobile communication terminal may identify whether an incoming call is received (S620).
Thereafter, as shown in FIG. 7(a), if the incoming call is identified to be received, the mobile communication terminal splits the screen to display the route guidance screen on a first split region and to indicate the call connection state information, e.g., the call being received, with, e.g., the opposite party's phone number or name on a second split region, i.e., the call reception window (S630) to identify whether the incoming call connection has been selected (S640).
Then, if the incoming call connection is identified to be selected, the mobile communication terminal may connect the call as shown in FIG. 7(b) (S650) and may display the call being connected on the second split region as the call connection state information (S660).
That is, if the user presses the call reception window saying “you have a call,” the mobile communication terminal connects the call—for example, automatically turns into hands-free mode, i.e., speaker phone mode, to connect the phone call, and if the call is connected, the call reception window is changed to say “line is busy” by which the call being ongoing is indicated.
At this time, in case the received number is included in the contact information, the call reception window displays the content such as name or company name as well as the image or picture contained in the contact information, and unless the received number is included in the contact information, the call reception window displays a preset image or picture, together with the received number.
In contrast, if the incoming call connection is identified to be not selected by the user, the mobile communication terminal sends a text message with preset content to the opposite party's mobile communication terminal that has sent the incoming call. For example, the mobile communication terminal may create a text message saying “Now I am driving so I can't respond to this call” and send the same to the opposite party's mobile communication terminal.
Next, the mobile communication terminal may identify whether the call connection is terminated (S670), and if the call connection is terminated, may remove the call reception window (S680) to display back only the route guidance screen. That is, if the call connection is terminated in the mobile communication terminal as the opposite party hangs up the phone, or the call reception window is pressed to disconnect the call, for example, the call reception window disappears from the route guidance image.
Although the case where the mobile communication terminal according to the present invention receives an incoming call is described as an example, the present invention is not limited thereto, and the present invention may also apply to the case where an outgoing call is transmitted.
For example, according to the present invention, if call connection mode is selected while the navigation service is in use, an opposite party's number is received from the user on the screen for call connection, an outgoing call is transmitted, and the screen for the call connection is removed. Then, 1) a call transmitting window displaying call connection state information is overlaid on the screen where the navigation service is provided, or 2) the screen where the navigation service is provided is split to display the route guidance image on a split portion of the screen and the call connection state information on another split portion of the screen.
Meanwhile, the above-described embodiments of the present invention may be created as computer-readable program and may be implemented in a general-purpose digital computer that operates the program using a computer-readable recording medium. The computer readable recording medium includes storage media such as magnetic storage media (for example, ROMs, floppy discs, hard discs, etc.), and optical reading media (for example, CD-ROMs, DVDs, etc.).
Although exemplary embodiments of the present invention have been described above, it may be understood by those skilled in the art that various changes or modifications may be made thereto without departing from the essential features of the present invention. Accordingly, it should be noted that the embodiments set forth herein are provided not for limiting the present invention but for describing the present invention and that the scope of the present invention is not limited thereby and thereto.
