Description

  The present invention relates to a mobile phone, and more particularly to a mobile phone that can be used in a plurality of countries.

  In mobile phones, free communication without borders has been realized by entering international communication networks (international roaming) from domestic communication networks.

  Such mobile phones that can be used in both domestic and overseas regions are configured to be communicable by a plurality of communication systems according to the communication system used in each country. Communication is performed by switching to a communication method according to the area where the mobile phone is currently located.

  Specifically, in Japan, the W-CDMA (Wideband Code Division Multiple Access) method has begun to be adopted as a communication method for third-generation mobile phones, while in Europe and the like, GSM (Global System for Mobile) is adopted as a second-generation communication method. (Communications) method is the mainstream, and it seems that it takes time to shift to the third generation communication method.

  Accordingly, mobile phones that can be used in Japan, Europe, and the like are configured to be communicable using two types of communication systems, the W-CDMA system and the GSM system. Communication is performed by switching between the W-CDMA system and the GSM system according to the country where the mobile phone is taken and used.

Patent Documents 1 to 6 disclose prior arts that reduce the time and effort of a user's operation when dialing to another country.
Japanese Patent Laid-Open No. 11-275206 JP 2001-61000 A JP-A-8-163639 JP 2001-119750 A JP 2003-163734 A JP-A-9-46408

  In conventional mobile phones, when making an international call, it is necessary for the user to manually input the “country code” using the numeric keys, and the operation is complicated. In addition, when making a call from Japan to an overseas country, it is necessary to input a number such as “connected company number + 010” at the top in addition to the country code. The above-described “010” is called an international prefix number. A number such as “connection destination company number + 010” is referred to as an international code in this specification.

  On the other hand, roaming has already been realized in the GSM area, and if you dial the destination international number after “+” regardless of the country, “operator number +010”, that is, the international code is input like Japan. You don't have to.

  In a mobile phone, a user can register a plurality of phone numbers as a phone book in a built-in memory. Further, in many cases, a telephone number transmitted by manual input or a telephone number that has received an incoming call is stored as history information, so that a call can be made without manually inputting the telephone number.

  However, if the place where the first call or call is received is different from the place where the call is made next time, it may not be possible to make a call using the telephone number remaining in the history as it is. Similarly, even if a telephone number is registered in the telephone directory so that a call can be made from a certain point in time, the country code or the business number must be changed if the place where the call is made changes.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a mobile phone capable of appropriately making a call outside a domestic country using a telephone number held in advance.

  In summary, the present invention is a mobile phone having a country code automatic addition mode as an operation mode, and includes first to third storage units and a telephone number processing unit. The first storage unit stores a first setting of whether the country code automatic addition mode is valid or invalid. The country code information to be automatically added is registered in the second storage unit. The third storage unit registers a telephone number. In the case where the first setting indicates that the country code automatic addition mode is valid, the telephone number processing unit has a predetermined telephone number designated by the user from among the telephone numbers registered in the second storage means. If it is a code, the designated telephone number is used as it is as the calling telephone number, and when the designated telephone number does not start with a predetermined code, the designated telephone number starts with the predetermined code and the country code information registered in the second storage means. To generate a calling telephone number.

  Preferably, the mobile phone further has an international code automatic addition mode as an operation mode, and the first storage means further stores a second setting indicating whether the international code automatic addition mode is valid or invalid, and The international code information to be automatically added is further registered in the storage means, and the telephone number processing unit, when the second setting indicates the validity of the automatic international code addition mode, Is replaced with a number corresponding to the international code information registered in the second storage means.

  According to another aspect of the present invention, a mobile phone having an international code automatic addition mode as an operation mode, the first storage unit storing a setting of whether the international code automatic addition mode is valid or invalid, and automatic addition A second storage unit for registering international code information; a third storage unit for registering a telephone number; and a telephone number processing unit. When the setting indicates that the international code automatic addition mode is valid, the telephone number processing unit starts from a telephone number registered in the second storage means by the user and designates the head of the designated telephone number designated by the user. Sometimes a calling telephone number is generated by replacing a predetermined code at the beginning of the calling telephone number with a number corresponding to the international code information registered in the second storage means, and when the head of the designated telephone number is not a predetermined code The designated phone number is used as the outgoing phone number.

  According to still another aspect of the present invention, there is provided a mobile phone having a country code selection mode as an operation mode, a first storage unit that stores country notation information and country code information in association with each other, and a designated phone number. A second storage unit that temporarily holds; a display unit that displays a plurality of pieces of country notation information; a transition instruction to a country code selection mode; and a selection instruction that selects one of the plurality of pieces of country notation information An input unit for inputting and a telephone number processing unit are provided. When there is an instruction to shift to the country code selection mode from the input means, the telephone number processing unit stops the transition to the country code selection mode when the second designated telephone number starts with a predetermined code, A transition determination means for shifting to the country code selection mode when the head of the number is not a predetermined code, and in the country code selection mode, receives a selection instruction from the input means, reads the corresponding country code information from the first storage means, and designates The read country code information is added to the head of the number.

  According to the present invention, even when there is a case where a call is made from Japan to a foreign country, a case where a call is made from within Japan to a country within Japan, and a case where a call is made from outside Japan to Japan, a call is made based on a common stored telephone number. Since this is possible, the load on the user can be reduced. In addition, since it is not necessary to check information such as a company number and a country code every time a call is made, the burden on the user is further reduced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

Base station 207 communicates with mobile phone 206 wirelessly.

  FIG. 4 is a diagram showing a table used as a telephone directory.

  Referring to FIG. 4, “Ichiro Suzuki” representing a name and “0123456789” representing a telephone number are associated and registered as first data in the table. As the second data, “Jiro Suzuki” representing the name and “+44123456789” representing the telephone number are associated and registered. Further, “Saburo Suzuki” representing the name and “0046010123456789” representing the telephone number are registered in association with each other as the third data.

  The first data is a telephone number registered on the assumption that a call is made from Mr. Ichiro Suzuki who is in the UK from the UK, which is in the GSM area. The first data is a telephone number registered on the assumption that a call is made to Mr. Jiro Suzuki from a country other than the UK within the GSM range. In this case, “+” and a country code “44” indicating the United Kingdom are added to the head of the telephone number. At the time of addition, the leading “0” of the telephone number is deleted.

  The third data is a phone number registered on the assumption that an international call will be made from Japan to Saburo Suzuki in the UK. In this case, the operator number “0046” is assigned to the first four digits, the international prefix number “010” is assigned to the subsequent three digits, and the country code “44” indicating the United Kingdom is followed. The leading 0 is deleted and continues.

  FIG. 5 is a diagram for explaining a situation where the invention of Embodiment 1 is preferably used.

  The first embodiment mainly reduces the burden on the user when the user makes an international call in the GSM area.

  Referring to FIG. 5, mobile phone 302 in area A country C can make a call to mobile phone 301 in area A (eg, GSM zone) in country C (eg, UK with country code “44”). Suppose you have registered your phone number.

  Then, as shown in the first data in FIG. 4, the telephone number is registered in the telephone directory in a form without a country code. Even if it is not registered in the phone book, communication is once performed between the mobile phones 301 and 302 in C, so that similar data remains in the incoming call history and outgoing call history.

  Here, consider a case where the user of the mobile phone 302 moves to country D and makes a call from the mobile phone 302 to the mobile phone 301. Then, since “+” and the country code are required at the head, the user cannot call the data as it is. Therefore, it would be convenient if a call could be made by simply adding “+” and a country code to the beginning of the called data. Therefore, the user effectively sets the country code addition processing function of the mobile phone. This setting is performed by the user using the input unit 8, for example, and a mode setting indicating that the setting is valid is stored in the area 16 in the memory 11 of FIG. 1.

  FIG. 6 is a flowchart for explaining the operation of the mobile phone according to the first embodiment.

  FIG. 7 is a diagram for explaining changes in the display unit corresponding to the flowchart of FIG. 6.

  The country code adding process will be described with reference to FIGS. When the country code adding process starts, first, in step S101, a telephone number selected manually or from a memory dial (phone book) is input. After the telephone number is input, the display on the display unit 9 is as shown on the screen P101. Screen P101 indicates that determination key 25 is assigned as a country code key.

  Subsequently, in step S102, a key is input to the mobile phone waiting for key input, and in step S103, it is determined what kind of key the input key is. If it is determined in step S103 that the country code key has been pressed, the process proceeds to step S104. On the other hand, when the call key 23 is pressed, the process proceeds to step S120 and a call process is performed.

  When the country code key is pressed and the process proceeds to step S104, it is determined whether or not the head of the input telephone number is “+”. If the telephone number starts with “+”, this telephone number is registered for making an international call (for example, from the UK to France) in the GSM area. "Followed by the country code. Therefore, if the head is “+”, there is no need to add a country code, so the process proceeds to step S105, and an error message is displayed on the display unit 9. Then, it again enters the key input waiting state in step S102.

  On the other hand, if the head is not “+” in step S104, it is determined in step S106 whether a country code list has been selected. In this case, the display unit 9 is in the state shown on the screen P102. When the display of “list” on the screen is selected by operating the cursor key 21 and the enter key 25, the process proceeds to step S107, and the country code can be selected from a list registered in advance. In this case, the display unit 9 is in the state shown on the screen P103. In this case, country names corresponding to the candidate numbers 01 to 09 are displayed on the display unit, and the user can select a country from which to make an international call.

  FIG. 8 is a diagram showing a country code table stored in advance in the memory 11 of FIG.

  As shown in FIG. 8, country names corresponding to candidate numbers 01 to 09 are registered such as Japan, UK, Italy, Switzerland, Spain, Germany, Portugal, the Netherlands, and France. Corresponding country codes are registered as “81”, “44”, “39”, “41”, “34”, “49”, “351”, “31”, “33”. The country codes associated with these country names are stored in advance in an area 17 for storing registration information in the memory 11 of FIG.

  Referring to FIGS. 6 and 7 again, on screen P103, for example, candidate UK is selected and highlighted by cursor key 21, and if enter key 25 is pressed, the process proceeds to step S109 to add the country code to be added. Will be determined. In this case, the country code to be added is 44.

  On the other hand, if the user does not select the country code list in step S106, the country code can be directly input. For example, in the case of the UK, the number key 20 is used to input “44”. After the input, the display unit 9 is in the state shown on the screen P104. When the enter key is pressed in step S109, the process proceeds to step S110, where “+” and the country code are added to the head of the telephone number displayed on the screen P101, and the display unit enters the state shown on the screen P105. At this time, when the head of the telephone number is “0”, the head “0” is deleted and then “+” and the country code are added. However, when the country code is a specific country such as Italy, the leading “0” is not deleted and the country code “+” is added as it is. Since whether or not to delete the leading “0” differs depending on each country, the corresponding information is registered in the memory 11 in advance, and the process of step S110 is performed with reference to this information.

  Then, a transmission process is performed in step S120 by instructing the start of transmission by pressing the transmission key 23 or the like. The display unit 9 in the calling process is displayed as a screen P106.

  At this time, if the automatic international code addition mode described later in the fourth embodiment is on, the leading “+” is converted into the business number and the international prefix number, and the screen is as shown in P107. Become.

  As described above, in the first embodiment, the country code can be easily added to the registered phone number or the manually entered phone number even if the user does not memorize the country code. You can make a call easily.

[Embodiment 2]
In the process described in the second embodiment, a country code is not input every time a user makes a call, but is registered by registering one country where a business partner or the like often makes an international call. A country code is automatically assigned at the time of. Since the position of the mobile phone at the time of registration and transmission is similar to the situation described with reference to FIG. 5, description thereof will not be repeated.

  FIG. 9 is a flowchart for explaining country code registration processing according to the second embodiment.

  FIG. 10 is a diagram for explaining changes in the display unit corresponding to the flowchart of FIG. 9.

  Referring to FIGS. 9 and 10, when the country code registration process is started, it is determined in step S201 whether or not the country code automatic addition mode is set. The user can determine in advance whether the country code automatic addition mode is on or off. This setting is stored in the area 16 for storing the mode setting of the memory 11 in FIG.

  If the country code automatic addition mode is off in step S201, the process advances to step S208, and a display (not shown) that the automatic addition mode is off is made and the process ends.

  On the other hand, if it is the country code automatic addition mode in step S201, the display unit 9 is in the state shown on the screen P201. In step S202, it is determined whether or not a list request is made by operating the cursor key or the enter key.

  If there is a list request, the process proceeds to step S203, and a country code list display such as screen P204 is displayed on the display unit 9. In step S204, the cursor key 21 is moved to select a country name. FIG. 10 shows a case where the United Kingdom is selected on the screen P205.

  When the country name is determined, the process proceeds to step S205, where the selected country name is converted into a country code for which correspondence is registered in advance, and “44” is displayed as shown on screen P202. Then, the process proceeds to step S207.

  On the other hand, if there is no list request in step S202, the user inputs the country code using the numeric keys 20. Also in that case, the display unit 9 is displayed as a screen P202. Then, the process proceeds to step S207.

  In step S207, a registration completion display like the screen P206 is displayed on the display unit 9, and the country code registration process ends.

  FIG. 11 is a diagram for explaining a registered automatic additional country code.

  By the country code registration process, as shown in FIG. 11, registration that the automatic additional country code is “44” is stored in the registration information storage area 17 of the memory 11 of FIG.

  FIG. 12 is a flowchart for explaining an operation at the time of transmission of the country code automatic addition processing.

  Referring to FIG. 12, first, a telephone number is input in step S301. This input may be performed using the numeric key 20 of FIG. 2, or a telephone number may be called from the telephone directory data in the area 15 or the incoming call history data in the area 14 of FIG.

  Subsequently, when it is specified in step S302 that an international call is to be made and a call start instruction is input by a call key or the like, it is determined in step S303 whether the automatic country code addition setting is on or off. The automatic country code addition setting is previously set by the user as ON or OFF, and is stored in the area 16 of the memory 11 in FIG. If the automatic country code addition setting is OFF, the process proceeds to step S306, and normal call processing is performed.

  On the other hand, if the automatic country code addition setting is ON in step S303, the process proceeds to step S304. In step S304, it is determined whether or not the head of the input telephone number is “+”. When the head is “+”, the displayed telephone number is estimated to be a telephone number with a country code corresponding to roaming in the GSM area, as in the second data in FIG. Proceeding to step S306, the outgoing call process with the input telephone number is performed.

  On the other hand, if the head is not “+” in step S304, the process proceeds to step S305, where “+” and a preset country code are assigned. Since the country code set in advance here is “44” corresponding to the United Kingdom as shown in FIG. 11, this number is assigned, and the outgoing call processing is performed in step S306.

  FIG. 13 is a diagram for explaining display on the display unit in step S305.

  Referring to FIG. 13, the display on the display unit immediately after the telephone number is input in step S301 is shown on screen P301. Since the top of this telephone number is not “+”, if the automatic country code addition setting is turned on in advance, the processing of step S305 is performed by instructing the start of transmission by a transmission key or the like. As a result, as shown in the screen P302, “+” and “44” are added to the head of the telephone number, and the calling process is performed.

  Referring again to FIG. 1, a mobile phone having the country code automatic addition mode of the second embodiment as an operation mode will be described.

  The cellular phone includes an area 16 for storing the setting of whether the country code automatic addition mode is on or off, an area 17 for registering country code information to be automatically added, an area 14 or 15 for registering a telephone number, and telephone number processing. And a control unit 7 corresponding to the unit.

  When the country code automatic addition mode is on, the control unit 7 selects the designated telephone number when the head of the designated telephone number designated by the user from among the telephone numbers registered in the area 14 or 15 is “+”. The phone number is used as it is, and when the designated phone number does not start with “+”, “+” is added to the beginning of the designated phone number and the country code corresponding to the country code information registered in the area 17 is added. The calling telephone number is generated.

  As described above, the mobile phone according to the second embodiment automatically registers the country code to be automatically added in advance, so that when the outgoing phone call is processed, the input phone number satisfies a specific condition. A country code is assigned. Therefore, when the country where the international call is made is determined, the user does not have to input the country code every time, so the burden of the user's input is reduced.

[Embodiment 3]
In the third embodiment, a case where an international code is automatically added to an input telephone number will be described. In this specification, the international code means a combination of the operator code and the international prefix number.

  FIG. 14 is a diagram for explaining a situation in which the invention of Embodiment 3 is preferably used.

  Embodiment 3 mainly reduces the burden on the user when the user makes an international call in Japan.

  Referring to FIG. 14, mobile phone 302 in D country of area A is able to make a call to mobile phone 301 in country A of area A (eg, GSM zone) (eg, UK with country code “44”). Suppose you have registered your phone number.

  Then, as shown in the second data in FIG. 4, the telephone number is registered in the telephone book in the form of “+” and the country code. Even if it is not registered in the phone book, once communication is performed between the mobile phone 301 in C and the mobile phone 302 in D, similar data remains in the incoming call history and outgoing call history.

  Here, consider a case where the user of the mobile phone 302 moves to Japan and makes a call from the mobile phone 302 to the mobile phone 301. Then, since the operator code such as “0046” and the international prefix number “010” are required at the top, the user cannot call the data as it is. Therefore, it is convenient if a carrier code such as “0046” and an international prefix number “010” can be simply added to the head of the called data and transmitted. Therefore, the user effectively sets the international code addition processing function of the mobile phone. This setting is performed by the user using the input unit 8, for example, and a mode setting indicating that the setting is valid is stored in the area 16 in the memory 11 of FIG. 1.

  FIG. 15 is a flowchart for explaining the international code registration process.

  FIG. 16 is a diagram for explaining changes in the display unit corresponding to the flowchart of FIG. 15.

  Referring to FIGS. 15 and 16, in the registration process, first, in step S401, it is set whether or not to select the international automatic addition mode. As shown in screens P401 and P402, the cursor key is operated to switch between on and off, and the mode is determined by pressing the enter key. If the automatic international code addition mode is set to OFF here, the process proceeds to step S404, and the display “set to OFF” as shown on the screen P403 is performed.

  When any key is pressed, the process returns to the normal screen P407 and the process ends. As an example of the normal screen P407, FIG. 16 shows a screen displaying time and date.

  On the other hand, when the international code automatic addition mode is set to ON as shown in the screen P402 in step S401, the process proceeds to step S402. In step S402, an international code can be input as in screen P404.

  In this case, “0046” corresponding to the operator code and the international prefix number “010” are input as the international code. This input is allowed within 10 digits, and if there is an input exceeding 10 digits, an error sound will sound.

  When the input of the required number of digits is completed, the determination key is pressed, and the process proceeds to step S403, and a registration completion display such as a screen P406 is displayed on the display unit. When any key is pressed, the normal screen P407 is displayed. Here, when there is no input for a predetermined time in step S402, a display for prompting the input as shown on the screen P405 may be performed to wait for input again.

  FIG. 17 is a diagram for explaining information registered as an automatically added international code.

  As a result of the registration processing shown in FIG. 15, “0046010” is stored in the predetermined area 17 of the memory 11 of FIG. 1 as an automatically added international code as shown in FIG.

  FIG. 18 is a flowchart for explaining the calling process when the international code automatic adding process is ON.

  Referring to FIG. 18, when an international code automatic addition process is transmitted, a telephone number is first input in step S501. This input may be performed by calling up data in the phone book, may be performed by referring to history data, or may be input by the user using the numeric keys for each digit.

  Then, in step S502, designation of an international call is made, and an outgoing call start instruction is issued by pressing the outgoing call key. In step S503, it is determined whether the automatic international code addition setting is on or off. The automatic international code addition setting is previously set by the user to be on or off, and is stored in the area 16 of the memory 11 in FIG. When the automatic international code addition setting is off, the process proceeds to step S506, and normal transmission processing is performed.

  On the other hand, if the automatic international code addition setting is on in step S503, the process proceeds to step S504. In step S504, it is determined whether or not the head of the telephone number input in step S501 is “+”.

  If the head is not “+” in step S504, it is considered that a telephone number as shown as the first or third data in FIG. 4 has been input. In the case of the first data, the country code is insufficient and cannot be transmitted even if an international code is added. In the case of the third data, there is no need to add an international code. Therefore, the process proceeds to step S506, and the input telephone number is used as it is for outgoing call processing.

  On the other hand, in step S504, if the head of the telephone number input in step S501 is “+”, the process proceeds to step S505, where “+” is replaced with a preset international code. Then, the process proceeds to step S506, and a transmission process is performed.

  FIG. 19 is a diagram for explaining a screen at the time of transmission of the international code automatic addition processing.

  Referring to FIG. 19, screen P501 shows a case where the telephone number of Jiro Suzuki, the second data in FIG. 4, is called from the phone book data in step S501 in FIG. 18, and the screen is displayed when the call key is pressed. As shown in P502, “+” is converted into the international code “0046010” registered in advance in the process described with reference to FIG. 15, and the outgoing call process is performed.

  If the international code automatic addition process described in the third embodiment is used, for example, when a telephone number prefixed with “+” is transmitted from Japan, the labor of inputting the operator code and prefix number each time is saved, The burden of user input is reduced.

[Embodiment 4]
In the fourth embodiment, the country code automatic adding process described in the second embodiment and the international code automatic adding process described in the third embodiment are used in combination.

  FIG. 20 is a diagram for explaining a situation in which the invention of Embodiment 4 is suitably used.

  Embodiment 3 mainly reduces the burden on the user when the user makes an international call in Japan.

  Referring to FIG. 20, mobile phone 302 in area A country C can make a call to mobile phone 301 in area A (e.g., GSM zone) in country C (e.g., UK with country code “44”). Suppose you have registered your phone number.

  Then, as shown in the first data in FIG. 4, the telephone number is registered in the telephone directory in a form without a country code. Even if it is not registered in the phone book, communication is once performed between the mobile phones 301 and 302 in C, so that similar data remains in the incoming call history and outgoing call history.

  Here, consider a case where the user of the mobile phone 302 moves to Japan and makes a call from the mobile phone 302 to the mobile phone 301. Then, the operator code, for example, “0046” and the international prefix number “010” are required at the head, and the country code “44” following the operator code is also required, so the user cannot call the data as it is. . Therefore, it is convenient if a carrier code such as “0046”, an international prefix number “010”, and a country code “44” can be simply added to the head of the called data. Therefore, the user effectively sets both the country code addition processing function and the international code addition processing function of the mobile phone. This setting is performed by the user using the input unit 8, for example, and a mode setting indicating that the setting is valid is stored in the area 16 in the memory 11 of FIG. 1.

  In the fourth embodiment, it is necessary to register the country code and the international code in advance, but since the same processing as that described with reference to FIGS. 9 and 15 is performed, the description will not be repeated.

  FIG. 21 is a flowchart for explaining the calling process in the fourth embodiment.

  Referring to FIG. 21, first, a telephone number is input in step S601. This input may be performed using the numeric key 20 of FIG. 2, or a telephone number may be called from the telephone directory data in the area 15 or the incoming call history data in the area 14 of FIG.

  Subsequently, when it is specified in step S602 that an international call is to be made and a call start instruction is input by a call key or the like, it is determined in step S603 whether the automatic country code addition setting is on or off. The automatic country code addition setting is previously set by the user as ON or OFF, and is stored in the area 16 of the memory 11 in FIG. If the automatic country code addition setting is OFF, the process proceeds to step S606.

  On the other hand, if the automatic country code addition setting is on in step S603, the process proceeds to step S604. In step S604, it is determined whether or not the head of the input telephone number is “+”. When the head is “+”, the displayed telephone number is estimated to be a telephone number with a country code corresponding to roaming in the GSM area, as in the second data in FIG. Proceeding to step S606, the processing is continued with the inputted telephone number.

  On the other hand, if the head is not “+” in step S604, the process proceeds to step S605, where “+” and a preset country code are assigned. Since the country code set in advance here is “44” corresponding to the United Kingdom as shown in FIG. 11, this number is assigned, and the process proceeds to step S606.

  In step S606, it is determined whether the automatic international code addition setting is on or off. The automatic international code addition setting is previously set by the user to be on or off, and is stored in the area 16 of the memory 11 in FIG. If the automatic international code addition setting is off, the process proceeds to step S609, where normal outgoing call processing is performed.

  On the other hand, if the automatic international code addition setting is on in step S606, the process proceeds to step S607. In step S607, it is determined whether or not the head of the telephone number after the processing of steps S601 to S605 is “+”.

  If the top is not “+” in step S607, the telephone number after the processing of steps S601 to S605 is the telephone number as shown as the first or third data in FIG. Conceivable. In the case of the first data, the country code is insufficient and cannot be transmitted even if an international code is added. In the case of the third data, there is no need to add an international code. Accordingly, the process proceeds to step S609, and the input telephone number is used as it is for the outgoing call processing.

  On the other hand, in step S607, if the head of the telephone number after the processing of steps S601 to S605 is “+”, the process proceeds to step S608, where “+” is replaced with a preset international code. Then, the process proceeds to step S609, and a transmission process is performed.

  As described above, in the fourth embodiment, when the phone number is stored in a mobile phone overseas such as a business trip destination, both the automatic country code addition setting and the automatic international code addition setting are valid after returning to Japan. Keep it. If an outgoing call is made in Japan as an international call, it is not necessary to enter a troublesome country code or an international code, thereby reducing the burden of user input.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
