1 is a flowchart illustrating a roaming service display process of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 1, when a mobile terminal is first moved from a home area to a roaming area and then power is applied to the mobile terminal and initialized, the mobile terminal determines whether the current location is a roaming area (step 101).

Here, the mobile terminal can determine whether the mobile terminal is currently located in a home region or a roaming region by comparing a mobile country code (MCC) included in a signal received from the network with a previously stored mobile country code. have.

For example, if the mobile country code of the home area stored in the mobile terminal is 450, if the mobile country code received from the network is not 450, the mobile terminal may determine that it is currently located in the roaming area.

In step 101, if it is determined that the mobile terminal is currently located in the roaming area, the display area of the display unit or the touch screen displays the first display area displaying the event information corresponding to the home area and the event information corresponding to the roaming area. The display is divided into a second display area (step 103).

Here, the event information corresponding to the home area may include, for example, an audio call, a video call, a message, etc., set from a home area, an alarm, a schedule, etc. set in the home area, and the like. The information may be information such as a phone number or text input by the user for transmitting to the mobile terminal of the home area.

In addition, the event information corresponding to the roaming region may include, for example, an audio call, a video call, a message transmitted from a mobile terminal of the roaming region, an alarm or a schedule set by a user in the roaming region, and the like. In addition, the mobile terminal may include information such as a phone number or text input by the user in order to transmit a video call or a message to a mobile terminal in a roaming area.

The mobile terminal also allocates a first memory area for storing event information corresponding to the home area and a second memory area for storing event information corresponding to the roaming area (step 105).

Here, the first memory area may be created at the time of manufacture of the mobile terminal or before the mobile terminal moves to the roaming area (ie, located in the home area). In addition, when the first memory area is already created, the mobile terminal may allocate only the second memory area having a predetermined size in order to manage event information corresponding to the roaming area separately from event information corresponding to the home area. .

Thereafter, the mobile terminal displays the time of the home area on the first display area and the time of the roaming area on the second display area (step 107).

Here, the mobile terminal adjusts screen brightness of the first display area and the second display area or displays different images based on the time of the home area and the roaming area displayed on the first display area and the second display area, respectively. It can be displayed as a wallpaper.

For example, when the time in the home area is 11 am and the time in the roaming area is 9 pm, the mobile terminal displays the first display area brightly and darkens the second display area so that the user can set the time. It may be configured to recognize the time zone of the home area and the roaming area easily and quickly through the brightness of the display area without checking.

In step 107, the mobile terminal may automatically set the time in the roaming area based on the time information provided from the mobile communication network in the roaming area, and then display the time in the second display area, and time information is provided from the mobile communication network in the roaming area. If not, the time correction value corresponding to the time zone of the roaming area is read from the database stored in the memory, and then the time read from the time provided by the internal clock of the mobile terminal (for example, the time of the home area). The time of roaming area can also be set by adding or subtracting the correction value.

The time of the home area displayed on the first display area and the time of the roaming area displayed on the second display area display and / or store the event occurrence information corresponding to the home area and the event occurrence information displayed on the roaming area, respectively. It is the time of the hour.

For example, when a predetermined message is displayed from the home area, the received message is displayed on the first display area, and the reception time of the message is displayed and stored based on the time of the home area.

Thereafter, when the steps are finished, the mobile terminal determines whether a predetermined display event for displaying information on the display area of the display unit or the touch screen occurs (step 109), and when it is determined that the predetermined display event has occurred, Determine the region corresponding to the generated event and display the generated event information in the display area corresponding to the determined region (step 111), and generate the event generated in the corresponding memory area based on the region corresponding to the generated event. Save the information (step 113).

For example, when a voice call is received from a home area, the mobile terminal displays caller information corresponding to the received voice call in the first display area and stores a reception record of the voice call in the first memory area. Here, the voice call reception record includes a voice call reception time based on the time of the home area.

Alternatively, when an alarm is set or a schedule is set in the home area, the alarm or schedule information is displayed on the first display area when the corresponding display time is reached based on the time of the home area.

If it is determined in step 109 that a predetermined display event has not occurred, the mobile terminal determines whether an input event has occurred (step 115). Here, the input event may be generated by the user operating a key provided in the mobile terminal or providing a touch input to the touch screen.

If it is determined in step 115 that a predetermined input event has occurred, the mobile terminal determines an activated display area among the first display area and the second display area (step 117).

That is, since the display unit or the touch screen of the mobile terminal is divided into a first display area and a second display area, in order for a user to use the mobile terminal, any one of the first display area and the second display area may be used. After selecting and activating, you must perform key input or touch.

The mobile terminal displays information corresponding to the event input in the display area determined in step 117 (step 119), and stores the information corresponding to the input event in the corresponding memory area.

For example, when a user selects and activates the first display area through a function key or a touch provided in the mobile terminal, and inputs a phone number to connect a voice call to a predetermined mobile terminal in the home region, The telephone number is displayed in the first display area and the calling information of the voice call is stored in the first memory area.

Alternatively, when the user selects and activates the second display area and inputs text to transmit a message to a predetermined mobile terminal in the roaming area, the input text is displayed on the second display area, and the message transmission information is displayed. 2 is stored in the memory area.

Subsequently, the mobile terminal determines whether the power is off, and if it is determined that the power is off, ends the roaming service display process of the mobile terminal according to an embodiment of the present invention, and if it is determined that the power is not off, proceeds to step 109 Go back and do the following.
