Description

A METHOD AND A MOBILE TERMINAL TO SIMPLIFY INTERNATIONAL
CALLS
TECHNICAL FIELD
The invention relates to calls made from a mobile phone capable of making wireless communication over a cellular network and particularly to a method and a mobile terminal which simplifies international calls made by a user with said mobile device.
When a user of a mobile terminal such as a mobile phone, PDA, capable to communicate over a cellular network such as GSM, leaves the country his SIM card is registered, attempts to make a call from his mobile terminal to any number in the country where his SIM card is registered, he has to add "+" sign, which is the international prefix or in addition country code of his country in front of each number to be called in the country where his SIM card is registered, in the event the number has not been recorded in the required form. With current technology, the only possible way to avoid adding the sign and codes is to add prefix a nd national code in front of each number, which the user may possibly call. Otherwise, in case of emergency or when driving, adding manually the prefix and national code to call someone becomes quite an unpractical procedure. Especially, it requires concentration on the device for a while when it is necessary to make such additions in front of the numbers recalled from the memory of the communication device.
Therefore, enabling a mobile terminal (such as mobile phone, PDA) user to easily call any number in the country where his SIM card is registered, when he is in abroad, without making any extra procedure, even if the number is not recorded suitable for calls from abroad, would eliminate all above-mentioned disadvantages.

In the invention, the procedure of adding characters required for an international call is either automatically performed by the mobile terminal, or the user defines the characters to be added and thereafter, mobile terminal adds these characters in front of the numbers to be called.
While application of the invention on a mobile phone is explained in details, this is absolutely not a restricting example. Actually, any terminal which can communicate over cellular network such as PDA, laptop can easily be used instead of a mobile phone.
Accordingly, a flowchart is given in Figure 1 with respect to automatic addition of required characters.
First of all user activates this feature by selecting a menu option "automatically add international prefixes" by using the keypad of the phone. After such option is selected, when the user in abroad, recalls or dials a phone number in the country where his SIM card is registered and presses "call" key, the processor of the mobile phone checks the content of the number displayed on the displayed and defines required procedures. As an alternative, this feature may be activated automatically without intervention of the user when the mobile phone leaves the country where SIM card is registered. These procedures are explained in figures for a better understanding.
In the first example as seen in Figures 2a and 2b, the phone number to be called (6) includes only a subscriber number (2) which is 369 54 85. On the other hand, in this example it is assumed that area code of GSM operator (5) which has provided SIM card is 533 and as it is known, 533 is an area code of a Turkish GSM operator. In this case, when the user presses "call" key in the keypad of the mobile phone, the processor automatically analyzes the number on the display and confirms that such number includes only subscriber number, therefore not appropriate for international calling procedure. Then the processor recalls the GSM operator area code and country code of the GSM operator from the SIM card and a utomatically adds " +" s ign, which i s the international calling prefix (3) and consequently 90, which is country code of Turkey and area code of GSM operator (6) in front of the number to be dialed (6). Thus, the final form of the phone number to be dialed (6) is +90 533 369 54 85 and when the call is made, this final form is displayed to the user on the display (1 ) of the mobile phone.
In the second example, as seen in Figures 3a and 3b, the number to be dialed (6) is assumed as 0542 369 54 85. This phone number includes 0542, which is area code of a GSM operator (5) operating in Turkey and consequently the subscriber number (2). In this case, when the user gives 'call' command to the phone, the processor analyzes the number on the display and confirms that the number is appropriate for international calling procedure. Then using its software, the processor adds international calling prefix (3) and consequently 90(4), which is country code of Turkey, where 054 operator is operating in front of the number to be dialed ( 6) a nd i n t he m eantime d eletes ' 0' i n 0542 G SM o perator c ode a nd makes the number suitable for international call.
In the third example, as seen in Figures 4a and 4b, the phone number to be dialed is (6) +90 535 369 54 85. In this case, when the user when the user gives 'call' command, the processor confirms that the number includes all characters required for an international call and allows direct calling without making an extra procedure. On the other hand, the user can manually define the characters to be added for an international call. An exemplary flowchart is given in Figure 5. In this flowchart, the user i s a ssumed to recall the n umber to be dialed from the phone book of the phone.
According to this flowchart, the user first defines the characters he wants to add by selecting among sub menu option included preferably under the phone book menu. This sub menu includes "add international calling prefix" and "add country code" options. On the other hand, "list country codes" option is included under "add country code" option.
Accordingly, after the user select the "add international calling prefix" option, when the user recalls or dials a phone number and presses "call" key, the processor of the mobile phone checks whether the selected number includes country code of the country where SIM card is registered and in case the number includes the country code, it adds "+" sign, however if it does not include country code, it passes the entered numbers without making any procedure until finding an entry with country code. For example, if we assume that SIM card is registered in Turkey, the mobile phone seeks "90" in front of each number commanded to call and adds + sign in front of each number meeting such requirement.
Furthermore, after adding each + sign, the processor displays a confirmation display and asks confirmation by the user and does not make the call unless the confirmation is made.
In another example, when the user selects "add country code" option in the menu of said phone and gives "call" command to call the defined number, the processor of the mobile phone adds + sign and selected country code to the number to be called and makes the call. Here, the user selects "list country codes" option in the menu to see country codes in the world and easily selects the country and its code by using up and down keys on the keypad. For example, when the user selects England, +44 is added in front of each number to be dialed by the processor. In addition, the processor may ask user to confirm before each call. In an alternative configuration of the invention, in order to allow the user to enable his mobile phone with required technical specifications (such as supporting wireless Java technology) operate any or all of the above explained features for adding international prefixes, a software together with data on related menu structure are uploaded to a server and the user who is entitled to access the server downloads the software and menu data to his mobile phone over a communication link such as Internet and after downloading is completed, the user runs the downloaded software and makes necessary adjustments on his mobile phone.
In an alternative configuration of the invention, in order to enable any mobile phone operate any or all of above mentioned features for adding international prefixes, a software and menu data related to mentioned menu structure are uploaded to SIM cars. Thus, when the user installs Sim card on any mobile phone, the processor of the phone runs the software on SIM card and ensures that related menu are added to the phone.
Although the present invention has been shown and described in terms of a preferred embodiment, it will be appreciated that changes and modifications will be evident to those skilled in the art from knowledge of the teachings of the present invention. Such changes and modifications, which do not depart from the spirit, scope and teachings herein, are deemed to fall within the purview of the invention as set forth in the appended claims.
