MOBILE COMMUNICATION APPARATUS BEING SET AT AUTO-DIALING FUNCTION AND CONTROL METHOD THEREOF}

The present invention relates to a mobile communication terminal in which autodial is set, and a control method thereof, and more particularly, when a user selects a predetermined outgoing telephone number from a call log, a call connection is made to a wrong place due to the autodialing function. The present invention relates to a mobile communication terminal in which auto dialing is set so as to reduce a case, and a control method thereof.

The mobile communication terminal is a terminal for making a voice call with the other party, and since the mobile communication network service is different in each country, it is common to use a different mobile communication terminal in each country to make a call in the country.

However, as overseas travel has become more common and people frequently visit and travel between countries, there have been requests from users to use mobile terminals used in other countries as they are. Through the international roaming service that can be used in Korea as well as mobile communication terminal used in Korea.

Accordingly, a function for enabling international roaming service has been added to mobile communication terminals.

That is, users set the international roaming service support state through the menu of the mobile communication terminal used in the country, and after leaving the country, they can make a phone call to a domestic user through the international roaming service from abroad.

In order to make a domestic call from abroad using international roaming, it is inconvenient to first input an international phone connection number that must be entered for an international call in the country and a country code to make a call. The problem is solved. If the user pre-sets an international dialing number and a country code, an autodialing function is added to the mobile terminal to automatically add the corresponding number each time a call is made.

For example, to make a call to a domestic party from China using a mobile terminal, a Korean national must dial '00', which is the international telephone connection number, and '82', which is the country code of the Republic of Korea. You must press the call key after entering a number (for example, 11-8080-7777, the first digit '0' removed from 011-8080-7777). If the autodial feature is enabled, the user must press '011-'. If only 8080-7777 'number is entered and a call key or transmission key is pressed, the number is automatically transmitted to '00 -82-11-8080-7777' number.

Of course, it is assumed that '00', which is the international telephone connection number in China, and '82', which is the country code of Korea, are set to autodialing.

By the way, while the conventional auto dialing function has a convenient side, it may be inconvenient for the user.

For example, a call that already contains an international dialing number and country code because, when the autodial feature is set, the preset country dialing number and country code is added to the telephone number you select or enter when you request all calls. Duplicated numbers are added to the preset international dialing number and country code.

This is especially the case when you make a call by selecting a specific phone number from the call log (or call record).

For example, if a user calls a friend in Korea while the auto dialing function is already set up in a foreign country, the call record area of the conventional mobile communication terminal includes the entire number where the actual call was made, that is, the international telephone connection number, the country code, and the other party. A phone number containing all the phone numbers is stored.

However, in this state, when the user selects the other party (or the phone number) stored in the call log again and presses the call key, the phone number already containing the international dialing number and country code is duplicated again by the autodialing function. It will include the international dialing number and country code.

Rather, it is a confusion and inconvenience to users, and has become a complaint of many users.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is that an autodialing function is available, but when a user selects a specific counterpart from a call log or an outgoing call, the user dials an international telephone number and country.

Furthermore, the user can select the outgoing phone number in the call log and display the outgoing phone number that can be connected properly by simply selecting it (for example, by displaying a specific icon). The user's convenience is increased because care is not required to check whether the autodial function is set.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates a schematic configuration of an entire communication network in which a mobile communication terminal in which autodialing is set according to a first embodiment of the present invention is included and used.

As shown in the figure, the mobile communication terminal 100 in which the auto dialing is set according to the first embodiment of the present invention can make calls using overseas roaming in other countries, for example, China as well as domestic calls. have.

On the premise of such an overall configuration, the configuration and function of the mobile communication terminal 100 in which auto dialing is set according to the first embodiment of the present invention will be described in detail.

As illustrated in FIG. 2, the mobile communication terminal 100 in which autodialing is set according to the first embodiment of the present invention may include a communication interface 110, a key input unit 120, a controller 140, and a display 130. ), The storage unit 150 is configured.

The communication interface 110 forms a communication channel with the base station to enable transmission and reception of mobile communication signals.

The key input unit 120 includes a plurality of key buttons, generates a key input signal according to a user's key button manipulation, and transmits the generated key input signal to the controller 140.

The display 130 is a place where a predetermined screen is displayed, and may include an LCD (Liquid Crystal Display) with low power consumption.

The storage unit 150 includes an autodialing setting unit 151, a caller information table storage unit 172, and a call log storage unit 156.

The autodialing setting unit 151 stores the setting state of the autodialing function according to a command by the user's manipulation of the key input unit 120, where the autodialing function is repeatedly input by the user for international calls when roaming overseas. International dialing number and the other country's country code are added automatically.

That is, for example, if the user enters the number '010-8080-1111' in China and presses the transmission key (or call key), the international dialing number '003' in China and the country code '82 in Korea Using the outgoing call number generated by generating an outgoing call number added, that is, '003-82-10-8080-1111', the call access signal is transmitted. Here, the international dialing number in China is assumed only as an example, and the actual international dialing number may be different, and the first number of the telephone number entered by the user in generating the outgoing telephone number, ' 0 'can be removed.

To this end, the autodialing setting unit 151 may automatically set an international telephone connection number and a country code added as described above. In the present embodiment, the international telephone connection number is set to '003' (international telephone connection number in China) and the country code is set to '82' (Korea) as an example.

The source information list storage unit 152 stores and matches a system ID and source information. Here, the system ID is information included in a signal received from a base station, and serves as basic data for distinguishing each country or region. And the source information refers to the country or region from which the current call is made, and preferably, the source information may be a national symbol and / or a local symbol having the same international telephone connection number. In other words, the source information may be stored in advance by binding to those having the same international dialing number.

An example of data stored in the source information list storage unit 152 is illustrated in FIG. 3.

In FIG. 3, a country name is shown as source information matched with a system ID and a corresponding system ID.

That is, in any one country, the system ID may be different for each region or each base station, and the mobile communication terminal 100 determines whether each system ID corresponds to the source ID list storage unit 152 of FIG. 3. It can be seen from.

As the source information, as shown in FIG. 3, only the corresponding country name is stored in the source information list storage unit 152 on the premise that a specific international telephone connection number is used globally within each country. For example, in China, it means that the same '003' can be used anywhere as an international telephone connection number. A more detailed description thereof will be described later.

The call log storage unit 156 is a place where the outgoing phone number and the source information are matched and stored, where the outgoing phone number is the total phone number finally included in the call connection request signal, whether or not the autodialing function is set or not. The source information is as described above.

An example of data stored in the call log storage unit 156 is illustrated in FIG. 4.

That is, the source information corresponding to each outgoing telephone number and the outgoing telephone number, for example, the country of origin, is stored in the call log storage unit 156.

The control unit 140 includes a call log writer 141, a call log display controller 142, and a call connection requester 143. First, the call log writer 141 is included in a signal received from a base station. The source information is extracted from the source information list storage unit 152 of FIG. 3 based on the system ID, and the source information is matched with the extracted source information and stored in the call log storage unit 156 as shown in FIG. Perform the function.

Here, the call log may be either a call success record or a call request record (ie, a call record). That is, if the call record is a call success record, only the counterpart phone number when the call is made will be stored in the call log storage unit 156. If the call record is a call request record, all the counterpart phone numbers attempting the call are recorded. Will be saved.

In the present embodiment, the call record is described as an example of the call request record, that is, the call record.

The call log display control unit 142 controls the display 130 to display a list of outgoing call numbers stored in the call log storage unit 156 when the user requests the key input unit 120 for manipulation. 5A and 5B illustrate an example in which outgoing telephone numbers are displayed on the display 130.

At this time, when the call log display control unit 142 displays a list of the outgoing phone numbers stored in the call log storage unit 156 on the display unit 130, outgoing call numbers matching the same source information as the current source information are distinguished. Can be displayed. As an example, it may be controlled to display a kind of icon (hereinafter referred to as a 'normal connection icon') in front of the highlighted or the outgoing call number.

That is, when the current call is made in China, the call log display control unit 142 displays a normal connection icon before the outgoing call number dialed in China (as can be seen from FIG. 4).

Here, the normal connection icon is an icon displayed for a phone number that does not require the user's attention when autodial is set to the user, that is, the autodial for the phone number in which the icon is displayed while the autodial function is set. This icon indicates that you do not have to worry about the resulting malfunction of the function.

That is, the auto dialing function always generates a new phone number by adding a preset international dialing number and country code to a telephone number entered or selected by the user. This autodialing function causes a malfunction. Therefore, it is necessary for the user to indicate which telephone number in the outgoing telephone number list requires attention or that the connection can be made by simply selecting it without requiring attention. This function is a normal connection icon. The reason for displaying the normal connection icon when the source information is the same is related to the features of the present invention and can be seen by referring to the following description.

When the call connection request unit 143 detects any one selection from the list of outgoing phone numbers displayed on the display 130 while the autodial function is set, the call connection request unit 143 extracts source information matching the selected outgoing phone number. If the extracted source information is the same as the source information matching the system ID at the time of making the call, the autodialing function is temporarily released. Here, the temporary release of the autodialing function means that the original autodialing function is restored to the activated state when the call is terminated.

Then, the call connection request unit 143 generates and transmits a call connection signal including an outgoing telephone number selected by the user.

For example, the call connection request unit 143 selects the second outgoing telephone number '003-82-11-222-3333' on the screen as shown in FIG. 5B, and the call log storage unit 156 of FIG. 4. ) Confirms that the country matched to the corresponding outgoing telephone number is 'China', and extracts source information matched to the current system ID from the source information list storage unit 152 of FIG. As an example, the source information is 'China'. This is the same as the country matched to the outgoing telephone number selected by the user, and therefore the call connection requester 143 temporarily releases the autodialing function, that is, stored in the call log storage unit 156 without additional international dialing number and country code. The call connection signal is transmitted using only the telephone number itself.

That is, the call connection signal includes the telephone number '003-82-11-222-3333' number stored in the call log storage unit 156.

If the call connection requester 143 does not temporarily cancel the autodialing function, the international dialing number and the country code are overlapped as shown in '003-82-003-82-11-222-3333'. As a result, normal calls cannot be made.

This process is the same when the user selects the third telephone number from the outgoing telephone number list of FIG. 5B.

That is, since the source information matched to the third telephone number is also 'China', the call connection request unit 143 temporarily cancels the autodialing function and makes a call connection request using the '010-333-4444' number. If the auto dialing function is not turned off, the call connection request will be made at '003-82-10-333-4444' and the actual dialing function will be wrong even though the actual user wanted to call the other party in China. The call connection is made to the established Korea.

As described above, since the normal connection icon is already displayed in front of the second and third phone numbers of FIG. 5B, the user can easily confirm that the connection can be made to a proper counterpart by selecting the corresponding phone number.

However, a normal connection icon is not displayed in front of the first phone number of FIG. 5B, and a user should pay attention when selecting and connecting a corresponding phone number.

Referring to FIG. 4, the first telephone number '011-111-1111' of FIG. 5B is a call from Korea, and this does not correspond to a condition for releasing the autodialing function. If the user selects the telephone number while the dialing function is set, the telephone number '003-82-11-111-1111 with the preset international dialing number' 003 'and the country code' 82 'added. 'Is created to make a call connection request. Of course, when the autodial function is executed, the first digit '0' is removed as described above.

As such, the call connection request unit 143 transmitting the call connection signal including the '003-82-11-111-1111' number results in conformity with the intention of the user. However, this is a coincidence and if the first phone number in Fig. 5B is not an originating call from Korea but an outgoing call from Japan, the call access signal using the '003-82-11-111-1111' number is It is a malfunction. In addition, even when calling from other countries in Korea, for example, the outgoing telephone number such as '001-44-10-111-1111' is stored in the call log storage unit 156, in which case the auto dialing function When activated, the call connection signal using the wrong phone number is transmitted, such as '003-82-01-44-10-111-1111'. Accordingly, the call log display control unit 142 does not display the normal connection icon for the first phone number of FIG. 5B so that the user pays attention when using the autodialing function.

Of course, if it is possible to distinguish whether the call from Korea is a call in Korea or a call from another country by analyzing the outgoing phone number, a normal connection icon may be displayed for the call in Korea. At this time, if the country code of auto dialing is set to '82' which is the country code of Korea, it can operate normally.

To distinguish between a call in Korea or a call from another country in Korea, the first digit of the outgoing phone number is the international call with information on the international dialing number (eg 001,003,00700, etc.) in Korea. It may be made by determining whether it corresponds to a connection number, or by determining the number of digits of an outgoing telephone number.

On the other hand, the call connection request unit 143, if the outgoing call number selected by the user is an outgoing call number where the normal connection icon is not displayed, the display 130 displays a popup window (not shown) for temporarily releasing the autodialing function. ), It is also possible to determine whether to temporarily disable the auto dialing function according to the user's input. In other words, the popup window for temporarily disabling the autodial function allows the user to recognize that the autodial function is currently activated when the user selects an outgoing call number without a normal connection icon. Rather, the user can confirm and prevent the call connection signal from being transmitted to the wrong telephone number.

If the user who checks whether the auto dialing function is temporarily released or not, for example, presses the confirmation key without modifying the outgoing phone number, the call connection request unit 143 adds the international dialing number and the country code as soon as the autodial function is set. Transmit one call connection signal.

Hereinafter, a control process of the mobile communication terminal 100 in which auto dialing is set according to the first embodiment of the present invention will be described with reference to FIGS. 6A and 6B. In the business card according to the present embodiment, description of each component of the mobile communication terminal 100 will be omitted.

First, a process of storing an outgoing call number or the like will be described with reference to FIG. 6A. When a call is made by a user's operation (step S1), the mobile communication terminal 100 transmits source information based on a system ID of a base station. Is extracted (step S3). For example, the country (or country code) that is currently calling can be extracted.

Subsequently, the mobile communication terminal 100 matches and stores the extracted source information and the outgoing telephone number (step S).

Next, referring to FIG. 6B, a process in which a user selects a specific outgoing telephone number from a call log and makes a call will be described.

First, the user sets the autodialing function (step S11). For example, set the international dialing number and specific country code used in the country where you are currently staying.

If the user detects a call record display request (step S13), the mobile communication terminal 100 displays a list of previously stored outgoing telephone numbers (step S15).

At this time, the mobile communication terminal 100 additionally displays a normal connection icon in front of the outgoing telephone number matched to the same source information as the current source information so that the user can easily recognize it (step S17).

When the user selects one outgoing telephone number from the displayed outgoing telephone number list (step S19), the mobile communication terminal 100 extracts previously stored source information matching the selected outgoing telephone number (step S21).

If the extracted source information is the same as the source information matched to the system ID at the time of making the call (step S23), the mobile communication terminal 100 temporarily releases the autodialing function (step S25) and the outgoing call selected by the user. The call connection signal including the number is transmitted (step S27).

In the above-described embodiment, the source information may be limited to a classification code for distinguishing whether the calling country or region currently makes a call, whether it is domestic or overseas. For example, '0' may be stored as source information when originating from Korea, and '1' as originating information when originating outside of Korea. In this case, when the user selects an outgoing telephone number matching the source information '1', the mobile communication terminal 100 may temporarily cancel the autodialing function.

Hereinafter, a mobile communication terminal 100 in which auto dialing is set up will be described with reference to FIG. 7.

As shown in the figure, the mobile communication terminal 100 in which autodialing is set according to the second embodiment of the present invention includes a communication interface unit 110, a key input unit 120, a controller 160, and a display unit 130. ), The storage unit 170 is configured.

Since the communication interface 110, the key input unit 120, and the display 130 are the same as in the previous embodiment, a detailed description thereof will be omitted.

The storage unit 170 includes an autodial setting unit 171, a table storage unit 172, and a call log storage unit 176. The autodialing setting unit 171 is also the same as in the previous embodiment, and thus will be described in more detail. Omit.

The table storage unit 172 includes a country code matching table 173, a phone number analysis table 174, and a country code list table 175.

The country code matching table 173 stores a country ID and a system ID included in a signal received from a base station. This is to confirm the country where the mobile communication terminal 100 is located. An example of a country code matching table 173 is shown in FIG. 8A.

As shown in the figure, a country code matching each system ID is stored in the country code matching table 173, and several system IDs may be matched to one country. This is because the system ID may be different depending on the location of the base station in each region even in the same country.

Meanwhile, the telephone number analysis table 174 stores data in which the system ID and the international telephone connection number are matched, an example of which is illustrated in FIG. 8B. Referring to the figure, international telephone connection number 003 is matched to the system IDs (13824, 13840, 13828) of China, and international telephone connection number 005 is matched to the system IDs (33859, 31541) of the United Kingdom. The international telephone connection numbers 001, 002, and 00700 are matched with the system ID 42103 of the Republic of Korea. As such, several international telephone connection numbers can be matched to a single country.

The system ID and the international telephone connection number of each country shown in FIG. 8B are merely random numbers, and may be different from the actual international telephone connection numbers.

The country code list table 175 stores a list of country codes. An example of a country code list table 175 is shown in FIG. 8C. In the country code list table 175, only the country code field is actually needed, but corresponding country names are shown for clarity.

It may be configured to use the information stored in the country code field of the country code matching table 173 of FIG. 8A without having to separately provide the country code list table 175.

The call log storage unit 176 is a place where the outgoing phone number is stored. As described later, the call log storage unit 176 uses the information stored in the call log storage unit 176 to check the other party's phone number and immediately re-dial the call. Can be.

The call record storage unit 176 stores an outgoing telephone number and a called country code corresponding to the outgoing telephone number. That is, when a user makes an international call during an international roaming call, the international roaming call phone number includes an international dialing number and a called country code. Stored at 176.

In this case, the outgoing phone number becomes the outgoing phone number when the call is made with the other party in the country. However, when the international call is made as described above, the outgoing call number and the country code are removed. The telephone number (hereinafter referred to as 'local number') becomes the calling telephone number. At this time, after removing the international telephone connection number and the country code, the telephone number with the number '0' at the forefront may be an outgoing telephone number. For example, if the international telephone number is '001-86-10-444-5555', the calling telephone number is '010-444-5555' and the called telephone number is '86'.

An example of data stored in the call log storage unit 176 is illustrated in FIG. 9, which will be described later in more detail.

The control unit 160 includes a call log writing unit 161, a call log display control unit 162, and a call connection request unit 163.

The call log writing unit 161 may determine whether an outgoing call number is an international call number when the outgoing call number is an international call number using a method of determining the number of digits of an outgoing call number and a method of analyzing a number progress format. The called country code and the local number are extracted, and the extracted local number is matched with the corresponding called country code as the calling telephone number and stored in the call record storage unit 176.

The method of determining the number of digits of an outgoing telephone number is, for example, that if the local number is limited to a maximum of 11 digits in Korea, it is determined that an international call is made when the number of digits of the outgoing telephone number is 12 or more.

In addition, the number progress format analysis method analyzes a format in which a telephone number is formed, and determines whether or not an international call is made by comparing and analyzing a telephone number at the head of the telephone number. For example, the call recorder 161 extracts an international telephone connection number that matches the system ID at the time of making a call from the base station from the telephone number analysis table 174 of FIG. It may be determined whether the calling telephone number is an international telephone number by determining whether the corresponding number is in front of the calling telephone number.

If it is determined that it is an international phone number, the call log writing unit 161 makes a call to a certain country by comparing the country number in the country code list table 175 of FIG. 8C with the number after the international call connection number in the outgoing phone number. Determine if it is a number. The call log writing unit 161 matches the local number with the country code determined as the destination country code and stores it in the call log storage unit 176.

On the other hand, the call recorder 161 extracts the country code matched to the system ID from the country code matching table 173 of FIG. 8A when the outgoing phone number is not an international call number as a result of the determination, and receives the extracted country code. The country code matches the outgoing phone number and stores it in the call log storage unit 176.

For example, when the user calls the other party's number '011-111-1111' in Korea, the call log writing unit 161 may have numbers 011, 002, 00700 (FIG. 8B) of the first part of the phone number. Since it does not correspond to any of the above, it is determined that it is not an international currency. From the country code matching table 173 of FIG. 8A, the country number '82' of the current call location is extracted, and the number is defined as the destination country code. Matching with the outgoing telephone number is stored in the call log storage unit 176. The first record of FIG. 9 corresponds to this.

As another example, when a user makes a call by entering a number '003-82-11-222-3333' from China to South Korea, the call log writing unit 161 may call the system from the phone number analysis table 174 of FIG. 8B. The international telephone connection number (here '003') matching the ID is extracted, and the result of comparing the extracted international telephone connection number with the first digit of the telephone number entered by the user is the same. Extract using the country code list table 175. The call log writing unit 161 matches the extracted '82' with '011-222-3333' (adding the number '0' to the front) corresponding to the local number and stores it in the call log storage unit 176. .

The second record of FIG. 9 corresponds to this.

Referring to the above description, when a user attempts to make a call by entering an outgoing telephone number '010-333-4444' in China, the call log writing unit 161 stores the call log with the same value as the third record of FIG. It can be seen that stored in the unit 176.

The call log display control unit 162 displays a list of outgoing call numbers stored in the call log storage unit 176 on the display unit 130 according to a user's request. That is, when the user requests, the outgoing telephone number is extracted from the call log storage 176 of FIG. 9 and displayed on the display 130 as shown in FIG. 10.

When the auto dialing function is set, the call connection request unit 163 detects a called country code matched to the selected outgoing phone number when one of the outgoing call number list displayed on the display 130 is detected by the user. 9 is extracted from the call log storage unit 176.

And the call connection request unit 163, if the extracted destination country code is not the same as the country code extracted by matching the system ID in the country code matching table 173 of FIG. 8A, the international dialing number according to the setting of the autodialing function. And, generate and transmit a call access signal using an outgoing telephone number selected by the user and a called country code matched with the selected outgoing telephone number.

For example, when the user selects the first outgoing telephone number of FIG. 10, the call connection requester 163 first extracts a called country number, that is, '82', that matches the corresponding outgoing telephone number, and then receives a signal received from the current base station. The country code matched to the system ID is extracted from the country code matching table 173 of FIG. 8A and the extracted country code is compared with the called country code.

If the result of the comparison is not the same, that is, if the destination country and the originating country to which the current call is to be made are not the same, the call connection request unit 163 is set by the international telephone connection number (for example, '003') and the user. Using the selected outgoing telephone number '011-111-1111' and the called country code '82', the entire telephone number, that is, '003-82-11-111-1111' is generated to transmit the call connection signal.

Here, the international telephone connection number is pre-stored by being input or selected by the user when setting up the autodialing. Since the setting of the autodialing is already known, a detailed description thereof will be omitted.

However, autodialing usually sets both the international dialing number and the country code. In this embodiment, only the international dialing number is used among the set values, and the country code is not the value set according to the autodial. By using the called country code stored in the record storage unit 176, an error due to the autodialing function can be minimized.

Hereinafter, a control process of the mobile communication terminal 100 in which auto dialing is set according to the second embodiment of the present invention will be described with reference to FIGS. 11A and 11B. In describing the present embodiment, description of each component of the mobile communication terminal 100 will be omitted.

First, a process of storing an outgoing telephone number or the like will be described with reference to FIG. 11A.

When a call is made by the user's operation (step S51), the mobile communication terminal 100 determines whether the outgoing telephone number is an international call number (step S53).

If the determination result is an international call number, the mobile communication terminal 100 extracts the outgoing telephone number by dividing it into an international telephone connection number, a called country code, and a local number (step S55).

Subsequently, the mobile communication terminal 100 stores the extracted local number as a calling telephone number by matching it with a corresponding called country code (step S57).

On the other hand, when the determination result in step S53 the outgoing telephone number is not an international call number (step S53), the mobile communication terminal 100 extracts the country code matching the system ID of the base station (step S59), the extracted country The number and the calling telephone number are matched and stored (step S61).

Next, referring to FIG. 11B, a process in which a user selects a specific outgoing telephone number from a call log and makes a call will be described.

First, the user sets the autodialing function (step S71). For example, you can set up an international dialing number that is used in your country. Of course, you can also set additional country codes.

If the user detects a call record display request (step S73), the mobile communication terminal 100 displays a list of previously stored outgoing telephone numbers (step S75).

In this state, when the user selects any one of the displayed outgoing telephone numbers (step S77), the mobile communication terminal 100 extracts the called country code matching the selected outgoing telephone number (step S79).

Subsequently, when the extracted destination country code is the same as the country code matching the system ID (step S81), the mobile communication terminal 100 transmits a call access signal using the extracted outgoing phone number (step S83). S87), if the extracted destination country code is not the same as the country code matching the system ID (step S81), a new call is made using both the international dialing number according to the autodial setting, the destination country code, and the outgoing phone number. A number is generated (step S85), and a call connection signal is transmitted using the generated telephone number (step S87).

In the above embodiment, the source information or the destination information (for example, the destination country code) is matched with the outgoing phone number and stored in the call log storage so that the user later selects one of the outgoing phone numbers stored in the call log storage. In this case, the process of temporarily releasing the auto dialing function according to the situation was described.

As another example, the mobile communication terminal 100 only stores predetermined information (hereinafter referred to as 'overseas roaming call information') according to whether the call is in an overseas roaming state with the calling phone number, and the user later corresponds to the call record. When the telephone number is selected and the call is attempted, the auto dialing function may be temporarily suspended depending on the situation.

Specifically, the mobile communication terminal 100 sets the information on whether the overseas roaming call is on when the call is in an overseas roaming state, and when the call is not on the overseas roaming state, whether the information is on the roaming call or not. Set to off to match the set roaming call availability information with the outgoing telephone number to store.

For example, one data field may be set and '1' may be stored in the corresponding field when the call is in an overseas roaming state, and '0' may be stored in the corresponding field when the call is in an international non-roaming state.

Here, overseas roaming means, for example, that the mobile communication terminal 100 registered in Korea is set to be used even in the foreign countries that are not registered, and the overseas roaming state is set in the mobile communication terminal 100 by the user. It may be made by manual operation or may be made automatically based on system information (for example, system ID) received from the base station. Since the method and process of the overseas roaming state is only known, a detailed description thereof will be omitted.

As such, when the outgoing roaming number and the overseas roaming call information are matched and stored while overseas roaming, when the user requests a call record while the autodialing function is set, the mobile communication terminal 100 provides a pre-stored outgoing telephone number list. If any one of these is selected by the user, the mobile communication terminal 100 extracts information on whether the international roaming call is matched to the outgoing telephone number selected by the user, and sets the extracted information on whether the international roaming call is on. If so, the autodialing function can be temporarily released and the call connection signal including the outgoing telephone number selected by the user can be transmitted.

Thus, for example, when a user of a mobile communication terminal 100 residing in Korea travels to China to make an overseas roaming call, the user may make a call (ie, a local roaming call) with the other party in China or in China. For the outgoing phone number that was talking to the other party in the country of (ie roaming international call), the international roaming call information set to on is matched and stored because the call is in overseas roaming state, and the user is later Selects the corresponding outgoing telephone number, the mobile communication terminal 100 releases the autodialing function temporarily and transmits a call connection signal even if the autodialing function is currently set, indicating that a wrong call connection is generated by the autodialing function. It can prevent.

That is, all overseas roaming is made for roaming local calls within China such as '010-8080-1111' made by a user traveling to China or roaming international calls outside China such as '003-81-10-8080-1111'. Since the call information is matched while being set to on, when the user selects the corresponding phone number from the call log, the call is released properly by temporarily disabling the autodialing function. In other words, it is possible to prevent the automatic dialing function from automatically adding international dialing number or country code.

Meanwhile, the mobile communication terminal 100 has a roaming international call (e.g., a call with a Japanese counterpart in China) and a roaming local call (e.g., a call with a counterpart in China in China) while overseas roaming is set. Roaming local call information to distinguish the case may be made to match the outgoing telephone number and stored.

If roaming local call information is set in this way, when a user later displays the call log list on the display unit, the user can inform the user about roaming local call with a specific icon.

That is, the call log list may display the calling phone number itself, but may be configured to display the other party's name corresponding to the calling phone number. If it is indicated whether the icon is a roaming international call or not, the user can easily determine whether the other party is correctly selected to make a call, thereby reducing the case of making a wrong call.

This example is shown in FIG. 12.

In the figure, an international call during overseas roaming is displayed as 'R' on the display unit of the mobile communication terminal 100, and a roaming local call during overseas roaming is displayed as a shaded telephone, and overseas Non-roaming state For example, calls in Korea are indicated by shaded phones. The type and configuration of these icons can be changed at any time.

For the detailed configuration of the mobile communication terminal constituting the above-described function, referring to the description and drawings of the first and second embodiments, those skilled in the art can infer the configuration.

On the other hand, the present invention is not limited to the above-described specific embodiments, it can be carried out by various modifications and modifications within the scope not departing from the gist of the present invention.
