Description

  The present invention relates to a mobile phone terminal device that uses a telephone number assigned in advance to each station and secures a line for communicating with another station via a predetermined radio base station, and in particular, has a number portability. The present invention relates to a mobile phone terminal device that can be implemented.

  There are a plurality of communication carriers (communication carriers) that provide services for terminals such as mobile phones to communicate.

  Each telecommunications carrier provides not only a similar type of call service, but also a unique communication service specially prepared for the convenience of users. For example, videophone, E-mail, HTML-mail, SMS (Short Message Service), etc. are prepared as special communication functions.

  As for the special communication functions as described above, there are cases where services can be provided for each telecommunications carrier and cases where it is not possible to provide services, so users using different telecommunications carriers can use mobile phones. When a communication line is connected, the type of communication function that can be used by the user on the calling side does not necessarily match the type of communication function that can be used by the user on the receiving side. May not be available.

  For example, when an SMS communication function that can be used by the calling user is selected and an email is sent to the other party, the service of the communication carrier used by the receiving user is the SMS communication. If it doesn't support the function, you can't send mail by SMS. Accordingly, the user on the transmission side must use the communication function to be selected properly so as to match the service of the communication carrier used by the user at the destination.

  In general, for destinations with high frequency of communication by phone call or e-mail, the phone number, e-mail address, name, etc. are often registered in the electronic phone book on the terminal such as a mobile phone. Since there are many cases in which the telecommunications carriers are aware, there were few problems that occurred when using different communication functions depending on the telecommunications carriers.

  In addition, when the network operator used by the other party is changed, the other party's phone number changes according to the changed carrier, so the other party's phone number registered in the electronic phonebook The number becomes unavailable, and as a result, it is known that the communication carrier used by the other party has been changed.

  However, when a number portability service is implemented in the future, only the telecommunications carrier that provides the communication service to the other party will change even though the other party's telephone number does not change. As a result, when the other party changes the communication carrier, a situation occurs in which, for example, only a specific mail function cannot be used even though the same telephone number as before can be used to connect to the other party and make a call. As a result, the originator is confused as to where the cause is. In addition, since it is expected that a mail that cannot be transmitted is repeatedly created and attempted to be transmitted, the operability is significantly deteriorated.

As a conventional technique related to the number portability service, a technique disclosed in Patent Document 1 is known. In Patent Document 1, on the system of the telecommunications carrier side, whether the telco carrier used by each subscriber is distinguished and whether the terminal on the calling side and the terminal on the called side have a contract for the short message service together It proposes to automatically identify whether or not.
JP 2005-191880 A

  However, the technology of Patent Document 1 relates to a system (exchanger or the like) on the telecommunications carrier side, and even if the technology of Patent Document 1 is adopted, the communication used by the partner station on the user's mobile phone. It is not always possible to distinguish between operators and available communication functions. In addition, in order to check whether each communication function can be used or not, it is necessary to make a communication from each station to the other station each time, so a cumbersome operation is required. Fees will also be charged.

  Even if the carrier used by the partner station is switched after the number portability service is implemented, the present invention allows the carrier used by the partner station and the available communication functions to be An object of the present invention is to provide a mobile phone terminal device that can be easily grasped.

  The mobile phone terminal device of the present invention is a mobile phone terminal device that uses a telephone number assigned in advance to each station and secures a line for communication with another station via a predetermined radio base station. The local station carrier information for distinguishing the communication carrier that provides the communication service to the local station is held, and the local station carrier information is transmitted to the partner station at the time of outgoing / incoming call or during a call. The carrier information transmission means for transmitting and the partner station carrier information for distinguishing the carrier providing the communication service for the partner station are received from the partner station, and the partner station carrier information corresponds to the telephone number of the partner station. And a partner station carrier information receiving means for storing the information.

  In the present invention, since the carrier information transmitting means on the first terminal on the transmitting side automatically transmits the local station carrier information, the partner station carrier information receiving means on the second terminal (counter station) on the receiving side Can receive the local carrier information of the first terminal and manage it in association with the telephone number of the first terminal.

  Accordingly, when the carrier that provides the communication service to the first terminal is switched, the content of the local carrier information transmitted by the first terminal also changes, so that the second terminal is changed from the first terminal. Based on the received latest local station carrier information, it is possible to automatically distinguish a communication carrier that provides a communication service to the first terminal and to distinguish a communication function that can be used by the first terminal. Become.

  In the mobile phone terminal of the present invention, when the carrier information transmitting means makes a transmission request to the radio base station, the carrier information transmitting means transmits the local station carrier information together with the telephone number of the partner station that is the connection destination. The partner station carrier information receiving means extracts and stores the partner station carrier information from the incoming call notification when receiving the incoming call notification from the radio base station.

  For example, according to the contents of the standard document (3GPP TS 24.008 V7.1.0) representing the standard of the third generation mobile phone, it is included in the transmission request (SETUP) that the calling terminal sends to the base station when making a call. In addition to the area for storing the telephone number of the calling terminal and the telephone number of the receiving terminal, there is an information area for transmitting information between the calling terminal and the receiving terminal (User- user) is prepared, if the local station carrier information is stored in this information area (User-user), the local station carrier information is notified from the originating terminal to the terminating terminal when making a call. Can do.

  In the present invention, since the terminal on the receiving side can receive the local station carrier information transmitted from the terminal on the transmitting side as the carrier information on the other side before the communication that causes the charging, such as a call, is started, It is possible to grasp the carrier information of the partner terminal without performing communication in which the above occurs.

  Further, in the mobile phone terminal of the present invention, when the counterpart station carrier information receiving means receives an incoming call notification from the radio base station, an incoming call response including the own carrier information is transmitted via the radio base station. It transmits to the other station.

  For example, according to the contents of the standard document (3GPP TS 24.008 V7.1.0) representing the standard of the third generation mobile phone, in the incoming response (CONNECT) sent to the base station by the receiving terminal when receiving a call Provides an information area (User-user) for transmitting information between the calling terminal and the receiving terminal, so that the information of the receiving terminal is stored in this information area (User-user). If the local carrier information is stored, the local station carrier information can be notified from the terminal on the incoming side to the terminal on the outgoing side at the time of the incoming call.

  In the present invention, before the communication for which charging is generated, such as a call, is started, the originating terminal can receive the local station carrier information transmitted from the terminating terminal as the counterpart station carrier information. It is possible to grasp the carrier information of the partner terminal without performing communication in which the above occurs. In addition, it is possible to mutually notify the latest local station carrier information between the calling terminal and the receiving terminal only by performing a one-way outgoing operation. After confirming the carrier information, a call or the like can be started.

  Further, the mobile phone terminal device of the present invention refers to the partner station carrier information associated with the partner station of the connection destination with respect to at least one of the operation for outgoing and the e-mail transmission, and the partner station carrier information According to the difference, a function restriction control means for automatically restricting available functions among a plurality of types of communication functions prepared in advance or automatically determining the priority order of the functions to be used is further provided. It is characterized by that.

  According to the present invention, the function restriction control means can select from among a plurality of types of communication functions prepared in advance according to the difference in the other party carrier information at the time of outgoing call or operation for sending an e-mail (for example, at the time of mail creation). The functions that can be used in the network are automatically limited or the priority order of the functions to be used is automatically determined, so that processing of communication functions that cannot be used by the partner station can be suppressed.

  For example, a videophone communication function can be used on the calling terminal, and a user on the calling terminal can use the videophone communication function on the receiving terminal even when the videophone communication function cannot be used on the receiving terminal. If the user does not know the proper communication function, the user may select the videophone function and start the outgoing call operation, which may cause unnecessary communication or billing or may refuse the connection.

  In addition, when using e-mail, there are multiple types such as normal e-mail, HTML e-mail, and short message. Whether each communication function can be used or not is provided to each terminal. Since it is determined by the difference between the telecommunications carriers and the contents of the contract, the mail communication function that can be used by the calling terminal may not match the mail communication function that can be used by the receiving terminal.

  However, by referring to the carrier information associated with the receiving terminal, it is possible to grasp the communication functions that can be used by the transmitting terminal. Therefore, the function restriction control means controls so that a communication function that cannot be used by the terminal on the receiving side is not selected.

  In addition, the mobile phone terminal device of the present invention is further characterized by further including a function restriction table that holds information on availability of each of a plurality of types of communication functions prepared in advance for each of a plurality of communication carriers. To do.

  In the present invention, by referring to the function restriction table, it is possible to easily grasp the communication function that can be used by the receiving terminal and the communication function that cannot be used from the carrier information associated with the receiving terminal. it can.

  Further, the mobile phone terminal device of the present invention uses the partner station carrier information associated with the partner station of the connection destination for at least one of the time of outgoing call and the operation for sending an e-mail. Identifying the availability of the first communication function selected by the operation, and if the first communication function is not available, select the second communication function that can be used according to the partner station carrier information; Operation support control means for automatically switching from the first communication function to the second communication function is further provided.

  In the present invention, when the first communication function selected by the operation of the user on the calling side cannot be used on the terminal on the receiving side, the second communication function usable on the terminal on the receiving side is selected. Since the operation support control means of the terminal on the transmission side is automatically switched, the convenience for the user is improved. That is, it is possible to prevent wasteful communication and billing or connection rejection from being made in advance.

  In the mobile phone terminal device according to the present invention, when both the first communication function and the second communication function are e-mail communication functions, the operation support control means includes the first communication function. The mail data created by using the application program is automatically copied as mail data used by the application program of the second communication function.

  In the present invention, mail data (for example, a text or a subject) created by using the first communication function application program is automatically copied as mail data used by the second communication function application program. Therefore, when the first communication function is switched to the second communication function after the mail is created, the user transmits the mail using the second communication function without recreating the mail. can do.

  In the mobile phone terminal of the present invention, when the operation support control means copies the mail data created by using the application program for the first communication function, the second information is included in the mail data. When a specific character code prohibited by the communication function is included, the corresponding character code is automatically converted into another usable character code.

  The character code of the character string transmitted as the body of the e-mail or the subject may or may not be acceptable, for example, a special character code such as a pictograph. Depends on the service provider's system and the contents of processing inside the terminal. Therefore, if the carrier system used by the calling terminal is different from the carrier system used by the receiving terminal, some characters in the mail created by the calling terminal will be received. May not be displayed correctly.

  In the present invention, when copying the created mail data, if the mail data includes a specific character code prohibited by the second communication function, the corresponding character code can be used. Since it is automatically converted into other character codes, all characters created on the caller terminal can be displayed correctly on the callee terminal.

  According to the present invention, since the carrier information transmitting means on the first terminal on the transmission side automatically transmits the local station carrier information, the reception of the other party carrier information on the second terminal on the receiving side (the other station). The means can receive the local station carrier information of the first terminal and manage it in association with the telephone number of the first terminal. Therefore, even after the number portability service is implemented, even if the telecommunications carrier used by the partner station is switched, the telecommunications carrier used by the partner station and the available communication functions can be easily used on its own terminal. I can grasp.

  One embodiment of the cellular phone terminal device of the present invention will be described below with reference to FIGS.

FIG. 6 is a schematic diagram showing a configuration example of a function control table of the terminal shown in FIG.

  In the present embodiment, it is assumed that the present invention is applied to terminal 100 shown in FIG. The terminal 100 is a mobile phone terminal. As shown in FIG. 1, the data transmission / reception unit 10, the transmission processing unit 20, the reception processing unit 30, the communication control unit 40, the application unit 50, and the key operation unit 60 The display unit 70 and the storage unit 80 are provided.

  The transmission processing unit 20 includes a carrier data adding unit 21, the reception processing unit 30 includes a data analysis unit 31 and a carrier determination unit 32, and the communication control unit 40 includes a function control unit 41 and a function. The determination unit 42 is provided, and the storage unit 80 is provided with a telephone directory recording unit 81 and a function control table 82.

  In FIG. 1, only main components directly related to the implementation of the present invention are shown, and actually various components are further provided in the same manner as a general mobile phone terminal.

  The data transmission / reception unit 10 performs wireless communication with a predetermined wireless base station belonging to a system on the side of a communication carrier that provides a communication service to the terminal 100, and secures a communication line necessary for communication such as a call.

  The transmission processing unit 20 processes data to be transmitted to the partner station. Further, the carrier data adding unit 21 provided in the transmission processing unit 20 holds data (herein referred to as carrier data) for specifying a communication carrier that provides a communication service to the terminal of the own station. The carrier data is automatically added to the transmission data.

  The reception processing unit 30 performs processing for receiving data transmitted from the counterpart station. A data analysis unit 31 provided in the reception processing unit 30 performs a process for extracting carrier data transmitted from the other station from the reception data, and a carrier determination unit 32 is a carrier extracted by the data analysis unit 31. Processing for determining data is performed.

  The communication control unit 40 performs basic control and communication control of the entire terminal 100. The function control unit 41 provided in the communication control unit 40 performs automatic control related to selection of various functions prepared in advance. The function determination unit 42 identifies whether the selected function or the function to be selected is available.

  The application unit 50 holds a plurality of application programs for realizing various practical functions. Specifically, an application program for operating the electronic telephone directory, an application program for operating electronic mail, and the like are provided in the application unit 50.

  The key operation unit 60 performs a process for accepting a user input operation. The display unit 70 is used for displaying character information registered in the electronic telephone directory, displaying the contents of a mail being created, and displaying the contents of a received mail.

  The storage unit 80 is a nonvolatile storage device capable of writing and reading various information. The storage unit 80 shown in FIG. 1 is provided with a telephone directory recording unit 81 and a function control table 82. The phone book recording unit 81 is used to hold phone book data. In this telephone directory, in addition to an area for holding information such as a telephone number and a name for each destination, an area for holding carrier data for specifying a communication carrier that provides a communication service to the terminal of the destination Is provided.

  The function control table 82 on the storage unit 80 holds information representing availability of various functions prepared in advance in a form that can be distinguished for each communication carrier. A specific example of this function control table 82 is shown in FIG.

  In the example illustrated in FIG. 6, 001 (DoCoMo), 002 (Au), 003 (Vodafone), and 004 (WILLCOM) are prepared as carrier IDs for distinguishing communication carriers, and a plurality of functions to be used are identified. Videophone, E-mail, HTML mail, SMS, and pictograms are assigned. “TRUE” shown in FIG. 6 indicates that each function can be used, and “FALSE” indicates that it cannot be used. By using the contents of this function control table 82, it is possible to manage the availability of various functions for each carrier ID. In addition, when the content of the service of each communication carrier is changed, the content of the function control table 82 may be updated according to the content of the latest service.

  By the way, when the number portability service is started, even if the telephone number of each terminal does not change, there is a possibility that the telecommunications carrier that provides the communication service to each terminal may be switched. Even if the above-described carrier data to be managed is managed for each telephone number in the telephone directory, inconsistency between the carrier data and the telephone number occurs. Therefore, in order to prevent the occurrence of such inconsistency, it is necessary to update the carrier data as needed in accordance with the latest situation, and processing as described below is required.

  The terminal 100 shown in FIG. 1 executes the process shown in FIG. 2A when making a call and further executes the process shown in FIG. 2B when receiving a call. Further, when a plurality of terminals 100 shown in FIG. 1 are used to make a call between the terminals 100, for example, a communication control sequence as shown in FIG. 5 is executed before the call is started. In FIG. 5, it is assumed that the terminal 100 (A) on the caller side and the terminal 100 (B) on the callee side communicate via a mobile phone communication network. This communication network includes a server 200 having a switching function and a radio base station.

  In the communication control sequence shown in FIG. 5, it is assumed that each terminal 100 (A), 100 (B) operates in accordance with the third generation mobile phone communication standard (3GPP TS 24.008 V7.1.0).

  When calling from the terminal 100 (A) on the calling side and calling the terminal 100 (B) on the receiving side, an input operation from the user of the terminal 100 (A) causes a change on the terminal 100 (A). The telephone number of the terminal 100 (B) that is the other party is specified, and the outgoing call process is executed.

  At this time, in the terminal 100 (A), the calling process shown in FIG. In step S11 of FIG. 2, the carrier data adding unit 21 adds the carrier data of the own station to the generated transmission request (SETUP). The carrier data adding unit 21 holds the carrier data of the own station in advance. Then, the transmission request (SETUP) to which the carrier data is added is transmitted to the communication network (wireless base station or the like) by the data transmitting / receiving unit 10 in the next step S12.

  In the 3rd generation mobile phone communication standard (3GPP TS 24.008 V7.1.0), in the transmission request (SETUP) sent to the base station by the terminal on the transmission side when making a call, step S51 in FIG. As shown, an area for storing the telephone number of the calling terminal, an area for storing the telephone number of the receiving terminal, and information for transmitting information between the calling terminal and the receiving terminal An area (User-user) is prepared. Therefore, in step S11 of FIG. 2, the carrier data adding unit 21 adds the carrier data of its own station (“001” corresponding to “Docomo” in the example of FIG. 5) to the information area (User-user) in the transmission request (SETUP). "Carrier ID)". Therefore, the carrier data of the local station can be transmitted simultaneously with the transmission of the transmission request (SETUP).

  Further, as shown in FIG. 5, the server 200 on the communication network generates an incoming call notification (SETUP) in step S52 in accordance with the received outgoing call request (SETUP) and sends it to the partner terminal 100 (B). Since the contents of the information area (User-user) in (SETUP) are stored as they are in the information area (User-user) of the incoming call notification (SETUP), the terminal 100 (A) includes the transmission request (SETUP) and transmits it. The carrier data of the own station is transmitted to the terminal 100 (B) on the receiving side as it is.

  When the receiving terminal 100 (B) receives an incoming call notification (SETUP) from the communication network, the processing shown in FIG. 2B is executed on the terminal 100 (B).

  In step S21 of FIG. 2, the data analysis unit 31 on the terminal 100 (B) analyzes the content of the received incoming call notification (SETUP), and includes the carrier data of the other station included therein, that is, the incoming call notification (SETUP). Extract the contents of the information area (User-user).

  In step S22 of FIG. 2, an application program for phone book processing existing in the application unit 50 on the terminal 100 (B) is started, and the phone book recording unit 81 on the storage unit 80 is accessed via this application program. Then, the telephone book data of a specific person corresponding to the other party telephone number (caller telephone number) in the incoming call notification (SETUP) is read.

  In the next step S23, the carrier data of the telephone book data of the specific person read in step S22 is compared with the carrier data of the partner station extracted from the incoming call notification (SETUP) in step S21. If both are equal, the telephone book data (carrier data) of the corresponding person is not changed, and this process is terminated. If the two do not match, the telephone book data (carrier data) of the corresponding person is likely to be changed, and the process proceeds to the next step S24.

  In step S24, a predetermined confirmation message is displayed on the display unit 70 in order to confirm to the user whether or not to register the changed carrier data of the partner station.

  In step S25, the state of the key operation unit 60 is monitored and a user input operation is detected. Only when an input operation indicating permission of registration is detected, the process proceeds to step S26.

  In step S26, the telephone book data of a specific person corresponding to the other party telephone number (caller's telephone number) in the incoming call notification (SETUP) is extracted from the incoming call notification (SETUP) in step S21 into the carrier data area. The carrier data is written, and the contents of the corresponding phone book data are updated to the latest information.

  Note that control may be performed such that step S24 and step S25 are omitted, and the telephone directory data is updated without user confirmation.

  In the communication control sequence shown in FIG. 5, the terminal 100 (B) on the receiving side sends an incoming response (CONNECT) in step S53 immediately after receiving the incoming notification (SETUP). CONNECT) stores the carrier data of terminal 100 (B). This control can be performed by the carrier data adding unit 21.

  In the third generation mobile phone communication standard (3GPP TS 24.008 V7.1.0), the incoming call response (CONNECT) sent to the base station as a response when the called terminal receives a call is sent to step S53 in FIG. As shown, an information area (User-user) for transmitting information between the terminal on the calling side and the terminal on the receiving side is prepared in addition to the area for storing the information indicating whether the response is made or rejected. .

  Accordingly, in step S53 of FIG. 5, carrier data (“AU” in the example of FIG. 5) is stored in the information area (User-user) in the incoming response (CONNECT) sent by the terminal 100 (B). Is stored and transmitted. Accordingly, the incoming side carrier data can be sent simultaneously with the sending of the incoming call response (CONNECT).

  Further, as shown in FIG. 5, the server 200 on the communication network generates an incoming response (CONNECT) in step S54 in accordance with the incoming response (CONNECT) received from the incoming terminal 100 (B), and transmits the incoming terminal 100 ( A), the content of the information area (User-user) in the incoming call response (CONNECT) is transmitted as it is to the terminal 100 (A) as the transmission source.

  Therefore, as shown in FIG. 5, each terminal 100 simply performs the outgoing / incoming operation to obtain the latest carrier data of the partner station, and associates it with a telephone number for each partner station using the phone book on the terminal 100 of the own station. Can be managed.

  In the example shown in FIG. 5, it is assumed that the terminal 100 (A) on the calling side and the terminal 100 (B) on the receiving side send carrier data in both directions in one call. It is possible to acquire the carrier data of the other party while repeating the outgoing / incoming call by simply transmitting the carrier data at any one time of the incoming call response.

  The operation in the case of controlling various communication functions using the telephone directory data including the contents of the carrier data acquired by the above processing is shown in FIGS.

  The process shown in FIG. 3 shows an operation for restricting the execution of some functions using the carrier data described above when creating an e-mail on the terminal 100 described above.

  In step S31, the destination of the electronic mail to be transmitted is determined according to the input operation of the user. That is, since phone book data including mail address information is registered in advance on the phone book recording unit 81, a large number of mails contained in the phone book data are detected according to the input operation detected by the key operation unit 60. Select the destination mail address from the addresses and determine the destination.

In step S32, the contents of the function control table 82 (see FIG. 6) are read.
In step S33, the function determination unit 42 acquires specific carrier data associated with the destination selected in step S31 from the telephone directory, and corresponds to the carrier data (carrier ID) acquired in the function control table 82. Extract data only. Then, the availability of each of various functions prepared in advance is determined according to the function control table 82.

  In step S34, the function control unit 41 performs control so that the user can select only usable functions based on the determination result of the function determination unit 42, and displays only the usable functions on the screen of the display unit 70. To do.

  For example, in the function control table 82 shown in FIG. 6, each function of E-mail, HTML mail, SMS, and pictograph is managed as a function related to electronic mail. Therefore, if the content of the carrier data (carrier ID) associated with the destination email address is “DoCoMo (001)”, the email can be used, the HTML email cannot be used, and the SMS cannot be used. It can be seen from the contents of the function control table 82 that the pictograph is available and cannot be used. Therefore, in this case, the function control unit 41 controls the display so that only normal emails can be selected. Therefore, it is possible to prevent selection of a function that cannot be used by the partner station.

  For example, when displaying multiple functions, it is not possible to use even if the display position and display form are controlled so that the priority of usable functions is raised and the priority of unavailable functions is lowered. Selection of various functions can be suppressed.

  Although not shown, even when a call is made, selection of a function that cannot be used can be prevented by performing the same processing as in FIG. 3 when the other party is selected. For example, in the function control table 82 shown in FIG. 6, the function of the videophone is managed, but the content of the carrier data (carrier ID) associated with the destination telephone number is “Au (002)”. If this happens, the videophone function cannot be used. Therefore, even if the videophone function can be used on the caller terminal 100, if the communication carrier providing the service to the callee terminal 100 is not compatible with the videophone, the caller terminal 100 is controlled by the function control unit 41 so that the videophone function cannot be selected.

  The process shown in FIG. 4 shows an operation for automatically switching from a function that cannot be used to a function that can be used by using the carrier data described above when creating an e-mail on the terminal 100 described above. ing.

  In step S41, one of e-mail operation application programs (for example, a program for HTML mail) provided in the application unit 50 is started according to the user's input operation, and the user's input operation is controlled under the control of this application program. Follow the instructions to create the body of the email and the subject.

  In step S42, the destination of the electronic mail to be transmitted is determined according to the input operation of the user. That is, since phone book data including mail address information is registered in advance on the phone book recording unit 81, a large number of mails contained in the phone book data are detected according to the input operation detected by the key operation unit 60. Select the destination mail address from the addresses and determine the destination.

In step S43, the contents of the function control table 82 (see FIG. 6) are read.
In step S44, the function determination unit 42 determines whether or not the function type (e-mail, HTML mail, SMS, etc.) of the mail created in step S41 is a function that can be used by the terminal on the receiving side.

  That is, the function determination unit 42 refers to the content corresponding to the carrier data (carrier ID) associated with the destination selected in step S42 in the function control table 82, and the type of the application program started in step S41. Alternatively, whether or not the function corresponding to the created mail type is available is identified from the contents registered in the function control table 82. If it is determined that the destination terminal cannot be used, the process proceeds from step S44 to step S45.

  In step S45, a predetermined message is displayed on the screen on the display unit 70 in order to ask for confirmation of the user who created the mail in step S41. For example, a message such as “The created mail cannot be received by the called party and will be switched to a function that can be received” is displayed and an input operation from the user is awaited.

  In step S46, an input operation from the user is monitored by the key operation unit 60, and whether or not to switch according to the content of the detected input operation is discriminated. If an input operation for selecting switching is detected, the process proceeds to the next step S47.

  If the user confirmation is unnecessary, steps S45 and S46 may be omitted and step S47 may be executed after step S44.

  In step S47, processing for transferring the contents of the created mail to a function usable by the destination terminal is executed. For example, if the application program started in step S41 also supports the switching destination mail, the second mail (e-mail, for example) that can be used by the destination terminal is automatically created on this application program. At the same time, the text of the first mail (for example, SMS) created in step S41 and the contents of the subject are copied into the second mail. If the application program started in step S41 does not support the second mail, another application program that can create the second mail is started, and the text of the first mail between the application programs and The contents of the subject are transferred and a second mail is automatically created from the first mail.

  For example, when it is recognized from the content of the function control table 82 that the destination terminal cannot use the pictogram, the character code is automatically set when the content of the first mail is copied to the second mail. Perform the conversion. That is, the character code of the pictograph is replaced with a character code such as a space. When automatic conversion of character codes is performed, a message indicating the conversion may be displayed.

  For example, when the first mail is HTML mail and the second mail is E-mail (composed of only text), the second mail is displayed in the body of the first mail. Since impossible data is included, data that cannot be displayed in the second mail is deleted or replaced with an equivalent character code.

  In step S48, the destination of the electronic mail to be transmitted is determined using the phone book data held in the phone book recording unit 81. That is, the mail address associated with the address selected in step S42 is taken from the phone book data, and the second mail address is automatically determined.

  In step S49, the second mail created by the processing up to step S48 is transmitted via the data transmitting / receiving unit 10.

  In the specific operation shown in FIG. 5 and the like, processing is performed so as to notify the carrier data held by each terminal when making a call for calling the partner terminal. It is also possible to process so as to notify the carrier data after starting or using e-mail. However, it is inevitable that communication charges will be incurred when making calls or sending / receiving emails.

  As described above, by applying the present invention to the control of a mobile phone terminal, etc., even if the carrier used by the partner station is switched after the number portability service is implemented, It is possible to easily grasp existing telecommunications carriers and available communication functions on the local station terminal.

  Therefore, it is possible to prevent the other station from selecting and transmitting a function that cannot be received. In addition, by automatically switching from a function that the partner station cannot use to a function that can be used, even if the carrier that provides the communication service to the partner station changes, it is possible to create a mail etc. with a relatively simple operation Operation can be completed and operability can be greatly improved.
