Description

  The present invention relates to a communication terminal device and a program.

Conventionally, since the mobile phone number is uniquely assigned to each communication carrier (carrier), the telephone number has to be changed when the user of the mobile phone changes. However, on October 24, 2006, a mobile phone number continuation system (number portability system) was implemented in Japan. This number continuation system is a service that can continue to use the same telephone number as before even if the mobile phone user changes the telecommunications carrier, and the system mechanism is disclosed in Patent Document 1 ing.
Japanese Patent Laid-Open No. 10-285285

   However, in the current number continuation system, changing the telecommunications carrier to join causes the following adverse effects. (A) The telephone number does not need to be changed, but the e-mail address must be changed. (B) It becomes impossible to use the communication service that the telecommunications carrier performs independently. (C) Charge discounts that are independently provided by carriers are no longer applied. Therefore, when the communication carrier is changed on the communication partner side, the mail address of the other party is changed, and mail transmission cannot be performed. In addition, it becomes impossible to use a communication service unique to a communication carrier used with a communication partner, for example, a short message service based on a unique standard. Furthermore, the charge discount applied with the communication partner, for example, the flat-rate call charge service with a specific partner of the same communication carrier is not applied.

  An object of the present invention is to appropriately notify that a communication carrier subscribed to by a communication partner has been changed.

According to the first aspect of the present invention, for each communication partner, a partner information storage means for storing and managing the partner telephone number and the carrier information in association with each other, and information on the carrier that the partner telephone number belongs to are acquired. Whether or not the telecommunications carrier has been changed by comparing the obtaining means and the telecommunications carrier information stored in association with the other party telephone number and the telecommunications carrier information obtained based on the telephone number A communication terminal apparatus comprising: a determination unit that determines whether the communication carrier has been changed by the determination unit; and a notification unit that notifies that the communication carrier has been changed.

  When the communication means communicates with a communication partner, the notification means notifies that the communication carrier of the other party telephone number has been changed (the invention according to claim 11).

  According to the present invention, it is possible to know that the communication carrier subscribed to by the communication partner has been changed, and various measures can be taken according to the change.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a mobile phone device as a communication terminal device, and FIG. 1 is a block diagram of a wireless communication system using this mobile phone device.
This wireless communication system has a configuration in which portable wireless communication networks of communication carriers (for example, communication carriers A, B, C,...) All over Japan are connected to each other. The station 2 and the exchange 3 are connected to a communication network (wireless communication network) 4. Here, when communication is performed between different communication carriers, a line connection to a communication partner is established by entering another wireless communication network 4. The information management device (information management server) 5 is provided for each of the communication carriers A, B, C,..., And does not belong to the communication carrier information of the currently belonging subscriber telephone number. It functions as a database management device that stores information such as information on the carrier of the telephone number to which the telephone number previously belonged.

  Under the number continuation system (number portability system), when connecting from a transmission source to a communication partner (transmission destination), it is performed as follows. That is, (1) Upon receiving the telephone number of the transmission destination on the side of the communication carrier to which the transmission source is subscribed, the communication carrier (the telephone number of the transmission destination is first assigned to the telephone number of the transmission destination) Identify the carrier that subscribed to In this case, for example, when the communication carrier B is specified from the transmission carrier A, (2) On this communication carrier B side, the above-mentioned database is referred to, and the telephone number of the transmission destination currently belongs. It is determined whether it is the telephone number of a subscriber. (3) As a result, if it is the current subscriber telephone number, the mobile phone device 1 of that telephone number is called and the line connection between the caller and callee is established. If it is a telephone number, it identifies the destination carrier. (4) In this case, for example, when the carrier C is specified as the destination, information indicating the destination is notified to the source carrier A. (5) On the side of the communication carrier A that has received this notification, a line connection is made to the destination communication carrier C side.

  Thereafter, as a result of the above operations (2) to (5) being repeated until the communication carrier to which the call destination is currently subscribed is identified, the caller of the call origination carrier A is currently calling It is possible to know which communication carrier the number (the other party's telephone number) is subscribed to. As a result, before the line connection between the caller and the callee is established, the caller can know the latest caller that the callee is currently subscribed to. If the line is cut off, it is possible to obtain the carrier information before the line is connected to the call destination. As a result, in the case of the purpose of acquiring the communication carrier information, the source communication carrier side sends the acquisition request to the partner's latest communication carrier via the communication network (wireless communication network) 4. I try to get it automatically.

FIG. 2 is a block diagram showing basic components of the mobile phone device 1.
The mobile phone device 1 includes a call function, an e-mail function, an Internet connection function (Web access function), and the like, and has a configuration centered on the central control unit 11. The central control unit 11 controls the overall operation of the cellular phone device 1 according to various programs in the ROM 12. The program area of the ROM 12 stores a program for realizing the present embodiment in accordance with operation procedures shown in FIGS. The RAM 13 is an internal memory having a work area, and is provided with a local telephone number storage unit M1, an address book storage unit M2, an incoming call history storage unit M3, a domain information storage unit M4, a mail storage unit M5, and the like.

  The own-station telephone number storage unit M1 includes the own-station telephone number and the communication carrier information that identifies the communication carrier to which the own-station telephone number belongs (communication carrier name or communication carrier ID, etc.). The mail storage unit M5 is a memory that stores received mail and transmitted mail. The address book storage unit M2, the incoming call history storage unit M3, and the domain information storage unit M4 will be described in detail later with reference to FIGS. Note that the storage contents of the RAM 13 are saved in a nonvolatile memory (for example, a flash memory) as necessary.

  The wireless communication transmitting / receiving unit 14 takes in a signal from the receiving side of the transmitting / receiving unit (baseband unit) connected to the antenna and demodulates the signal into a received baseband signal, and then transmits audio from the receiving speaker 16 via the audio signal processing unit 15. Output. Further, the wireless communication transmitting / receiving unit 14 takes in the audio data input from the transmission microphone 17 from the audio signal processing unit 15, encodes it into a transmission baseband signal, gives it to the transmitting side of the transmitting / receiving unit, and transmits it from the antenna Output. On the other hand, the display data received and acquired via the wireless communication transmitting / receiving unit 14 by the electronic mail function and the Internet connection function is given to the display unit 18 and displayed.

  The operation unit 19 performs dial input, character input, numerical value input, command input, and the like, and can perform power on / off operation, voice (phone) / mail outgoing operation, voice (phone) / mail incoming operation, and the like. The central control unit 11 executes processing according to a key input signal from the operation unit 19. The RTC (real-time clock module) 20 constitutes a clock unit, and the central control unit 11 acquires the current date and time from the RTC 20.

FIG. 3 is a diagram for explaining the address book storage unit M2.
The address book storage unit M2 stores partner information (address book record) arbitrarily registered by the user in advance for each communication partner. The “ID”, “name”, “phone number”, “mail address”, “ Each item includes a “telecom carrier”, “change date / time”, and “change flag”. “ID” is a series of Nos identifying partner information, “name” is the name of the partner, “phone number” is the partner phone number, “mail address” is the partner mail address, and “communication carrier” When the other party is a telecommunications carrier that has joined and the other party changes the telecommunications carrier using the number continuation system, the contents are rewritten to the changed telecommunications carrier. “Change date / time” indicates the date / time when the telecommunications carrier was initially registered (new registration) or the date / time set according to the change, and the “change flag” indicates whether the telecommunications carrier was changed. “1” is set according to the change, indicating that the carrier has been changed.

 Here, the central control unit 11 checks whether or not the “communication service provider” in the address book storage unit M2 has been changed, and if it has been changed, the “communication service provider” is changed to a new communication service. The batch change processing for batch rewriting the user information is executed periodically (for example, once a week / once a month) or in response to a user operation. At that time, the central control unit 11 automatically acquires the latest communication carrier of the other party via the communication network (wireless communication network) 4 as described above, and selects the corresponding “communication carrier” in the address book storage unit M2. In comparison, it is determined whether or not they match, that is, whether or not the carrier has been changed. If they do not match (if the carrier has been changed), the current date and time are determined. In addition to being set as “change date and time”, the “communication carrier” is rewritten with new communication carrier information.

 Here, when the batch change process is executed by a user operation, the central control unit 11 is configured to perform the change notification (communication carrier change notification) during the change process. Is automatically executed at the time of voice transmission, mail transmission, and voice reception. Also, the mail address can be changed at the time of batch change processing by a user operation, but at the time of periodic batch change processing, the mail address can be changed at the time of voice transmission, mail transmission, and voice reception.

FIG. 4 is a diagram for explaining the incoming call history storage unit M3.
The incoming call history storage unit M3 stores the incoming call contents as history information for each incoming voice call (incoming call) and incoming mail, and includes “ID”, “incoming date / time”, “name”, “phone number”, Each item includes “mail address”, “communication carrier”, “change date / time”, and “change flag”. The “communication carrier”, “change date / time”, and “change flag” are the same as the “communication carrier”, “change date / time”, and “change flag” in the address book storage unit M2 described above. When the communication carrier of the telephone number has been changed, the content of “communication carrier” is rewritten to the changed communication carrier. The batch change process described above is executed also for the incoming call history storage unit M3.

 In the incoming call history storage unit M3 as well, when the batch change process is executed by a user operation, the change is notified at the time of the change process. However, the batch change process is automatically performed periodically. When executed, the change is notified at the time of voice transmission, mail transmission, and voice reception. Also, the mail address can be changed at the time of batch change processing by a user operation, but at the time of periodic batch change processing, the mail address can be changed at the time of voice transmission, mail transmission, and voice reception.

FIG. 5 is a diagram for explaining the domain information storage unit M4.
The domain information storage unit M4 stores domain information of each telecommunications carrier, and the domain information for each telecommunications carrier is information registered in advance by a user operation. This domain information storage unit M4 is used when the domain information included in the partner mail address is changed according to a new communication carrier when the communication carrier of the communication partner is changed.

  Next, the operation concept of the cellular phone device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. In other words, in addition to the recording medium, an operation peculiar to this embodiment can be executed by using a program / data supplied externally via a transmission medium.

FIG. 6 is a flowchart showing an outline of the overall operation of the mobile phone device 1.
First, in response to a power-on operation (step A1), the central control unit 11 turns on the main power supply (step A2), executes various initialization processes (step A3), and then enters a standby state. . Here, it is checked whether or not a registration instruction operation has been performed on the address book storage unit M2 / domain information storage unit M4 (YES in step A4). If the registration instruction operation is performed, the registration process of FIG. Move (step A5). If an address book display instruction operation for displaying and outputting the contents of the address book storage unit M2 is performed (YES in step A6), the process proceeds to the address book display process of FIG. 8 (step A7).

 In the standby state, the central control unit 11 refers to the timing information from the RTC 20 and monitors whether or not the batch change timing for periodically executing the batch change processing described above has been reached (step A8). ). The batch change timing is an execution timing that is arbitrarily set, for example, once a week or once a month. For example, if the unused time zone of the mobile phone is set like 3:00 am, the midnight of the weekly and monthly changes may be set as the execution timing of the batch change process. Here, when the batch change timing is detected (YES in step A8), the process shifts to batch change processing A in FIG. 9 (step A9). If a batch change instruction operation is performed (YES in step A10), the process proceeds to batch change processing B in FIG. 10 (step A11).

 If a voice / mail transmission operation is performed in the standby state (YES in step A12), the process proceeds to the voice / mail transmission process of FIG. 11 (step A13), and there is a voice / mail reception. If YES in step A14 (YES in step A14), the flow shifts to voice incoming / mail incoming processing in FIG. 12 (step A15). If a power-off operation is performed (YES in step A16), a power-off process is executed (step A17), and this flow ends. If any other operation is performed ( As a process corresponding to this operation, for example, a mail creation process, an internet connection process, etc. are performed (step A19).

FIG. 7 is a flowchart for explaining the registration process (step A5 in FIG. 6) in detail.
First, when the registration to the address book storage unit M2 is instructed (YES in Step B1), the central control unit 11 waits for input of the “name”, “phone number”, and “mail address” of the registration target partner. (Step B2). Here, when arbitrary information is input from the operation unit 19, the wireless communication transmission / reception unit 14 transmits and outputs an acquisition request for the communication carrier information with the input telephone number as a destination (destination) (step B3). ). When the latest telecommunications carrier information transmitted in response to this acquisition request is obtained (YES in step B4), the "name", "telephone number", "mail address" and the "telecommunications carrier" are addressed. In addition to the additional registration in the book storage unit M2, the current date and time is acquired from the RTC 20, and this current date and time is additionally registered in the address book storage unit M2 as "change date and time" (step B5). Thereafter, until an end operation for instructing the end of registration is performed (YES in Step B6), the process returns to Step B1 described above, and the registration process in the address book storage unit M2 is repeated.

 If registration to the domain information storage unit M4 is instructed (NO in step B1), the system waits for input of domain information (step B7). Here, when the domain information of the communication carrier is input from the operation unit 19, the process proceeds to step B8, and this domain information is additionally registered in the domain information storage unit M4. Thereafter, until an end operation for instructing the end of registration is performed (YES in Step B6), the process returns to Step B1 described above, and the registration process in the domain information storage unit M4 is repeated.

FIG. 8 is a flowchart for explaining the address book display process (step A7 in FIG. 6) in detail. FIG. 15 is a diagram showing an address book screen displayed by executing the address book display process.
First, the central control unit 11 displays and outputs the address book screen on the display unit 18, and after accessing the address book storage unit M2 and designating the "ID" of the first record (step C1), this designated ID. Corresponding partner information “name”, “telephone number”, “mail address”, “communication carrier” is read out and displayed on the address book screen (step C2).

  Then, the icon corresponding to the “telecom carrier” (“A” in the example of FIG. 15) is displayed in association with the partner information (step C3), and then the “telecom carrier” of this partner telephone number is displayed. By comparing with the “telecom carrier” in the local station telephone number storage unit M1, a match / mismatch between the two is determined (step C4), and the determination result is displayed as an icon (step C5). In the example of FIG. 15, the “same” icon indicating a match between the two is displayed. Further, referring to the “change flag” of the partner information corresponding to the designated ID, it is determined whether or not the “communication carrier” of this partner telephone number has been changed (step C6), and the “change flag” is “1”. If "", a change icon is displayed and output (step C7). In this case, as shown in FIG. 3, since the “change flag” of the first record is “0” and the “communication carrier” is not changed, the changed icon is not displayed.

  After displaying the partner information for one record in this way, it is checked whether there is a display space on the address book screen (step C8). Here, as shown in FIG. 15, if information for two records (for two persons) can be displayed on the address book screen, it is determined that there is a space when the information for the first record is displayed. In this case, after returning to step C1 and specifying the “ID” of the second record, the other party information “name”, “phone number”, “mail address”, and “communication carrier” are read out in the same manner. After display output (step C2), various icons are displayed and output. In this example, “B” is displayed as an icon corresponding to “telecom carrier” (step C3), and an “different” icon indicating a mismatch with the local carrier is displayed (step C5). In addition, “change” is displayed as an icon with change indicating that “telecom carrier” has been changed (step C7).

  When the information of the second record is displayed on the address book screen, the process proceeds from step C8 to step C9 to check whether display scrolling is instructed by the user operation. Here, when the scroll button in the address book screen is operated and display scroll is instructed, the process returns to step C1 and the next “ID” is designated. Thereafter, the above operation is repeated, but the scroll instruction is issued. If not (NO in step C9), it is checked whether or not the close button for closing the address book display is operated (step C10), and the process returns to step C9 until a close instruction is received and waits for an instruction.

  FIG. 9 is a flowchart for explaining in detail the batch change processing A (step A9 in FIG. 6) that is periodically started. The central control unit 11 stores the address book storage unit M2 and the incoming call history storage unit M3. Access is performed, and the partner information that has passed a predetermined period (for example, 5 days) from the “change date / time” is specified as a batch change processing target while comparing the “change date / time” with the current date / time (step D1). In other words, in order to narrow down the processing target of batch change, the partner information within a predetermined period from “change date and time”, that is, the partner information immediately after new registration or the partner information immediately after changing the telecommunications carrier is excluded from the processing target. Other partner information is specified as a processing target.

  Here, one of the other party information is specified from each of the other party information specified as the processing target, and the other party telephone number is read out, and an acquisition request for the carrier information is made (step D2). That is, in order to automatically acquire the latest partner of the other party via the communication network (wireless communication network) 4 as described above, a request for acquiring the carrier information along with the other party telephone number is sent from the wireless communication transmitting / receiving unit 14. Make outgoing calls. When the latest communication carrier information transmitted in response to this acquisition request is received and acquired (YES in step D3), the address book storage unit M2 and the incoming call history storage unit M3 are based on this communication carrier information. A telecommunications carrier information change process for changing the “telecommunications carrier” is executed (step D4). Thereafter, until all the specified processing targets are designated (YES in step D5), the process returns to the above-described step D2, and the above-described operation is repeated while designating the next processing target.

  FIG. 13 is a flowchart for explaining in detail the telecommunications carrier information change process (step D4 in FIG. 9 and the like). The central control unit 11 is stored in the address book storage unit M2 and the incoming call history storage unit M3. Among the “communication carriers”, the “communication carrier” in the designated partner information is compared with the “communication carrier” received and acquired at this time, and a match / mismatch between the two is determined (step H1). As a result, if the two match (NO in step H1), the "communication carrier" has not been changed, so this flow ends. If the two do not match (YES in step H1), " Since the “communication carrier” has been changed, the “communication carrier” in the address book storage unit M2 and the incoming call history storage unit M3 is rewritten with the latest communication carrier information acquired this time (step H2). ). Then, the current date and time are set in the “change date and time” (step H3), and “1” is set in the “change flag” (step H4).

  FIG. 10 is a flowchart for explaining in detail the batch change process B (step A11 in FIG. 6) started to be executed by a user operation. The central control unit 11 stores the address book storage unit M2 and the incoming call history storage unit M3. Access is made and all the other party information is specified as a processing target (step E1). Then, in the same manner as described above, after designating one of the other party information specified as the processing target, and reading out the other party telephone number and making an acquisition request for the carrier information ( Step E2) When receiving and acquiring the latest carrier information transmitted in response to this acquisition request (YES in Step E3), the carrier information changing process of FIG. 13 is executed (Step E4).

  Then, the process proceeds to step E5, where it is checked whether the partner's “change flag” is “1”. If the carrier information is changed during the current batch change process, or the carrier information that was previously used is changed. When the carrier information is changed during the change process, the “change flag” is “1”. If the “change flag” is “0” (NO in step E5), the process proceeds to step E8, where it is checked whether all specified processing targets have been specified, and the process returns to step E2 until the specification is completed. If “Flag” is “1” (YES in Step E5), a change notification screen for communication carrier information is displayed and output to notify that the communication carrier information has been changed (Step E6).

  FIG. 16 is a diagram showing a change notification screen for the communication carrier information. A message is displayed indicating that the communication carrier for the other party's telephone number has been changed from “A” to “B”, and the communication business described above is displayed. In addition to the icon corresponding to the operator, the comparison result between the “telecom carrier” of the other party's phone number and the local phone number “telecom carrier” is displayed as an icon. In the illustrated example, “A” and “same” are changed to “B” and “different”. Here, if the confirmation button in the change notification screen is operated, the process proceeds to the next step E7 to execute the mail address change process of FIG. Thereafter, until all the specified processing objects are designated (YES in step E8), the process returns to the above-described step E2, and the above-described operation is repeated while designating the next processing object.

  In the automatic batch change process A shown in FIG. 9, the change notification of the communication carrier and the change of the mail address are performed at different timings, but the batch change by the user instruction shown in FIG. In the process B, the change notification of the communication carrier is performed at the time of batch change, and the mail address can be changed.

FIG. 14 is a flowchart for explaining in detail the mail address changing process (step E7 in FIG. 10 and the like).
First, the central control unit 11 sequentially searches the contents of the address book storage unit M2 / incoming call history storage unit M3 from the top thereof to identify a partner whose “change flag” is “1”, and the partner mail address is changed. It is notified that it is necessary (step J1).
FIG. 17 is a diagram showing a mail address change necessity inquiry screen. This inquiry screen displays “1 manual change”, “2” in addition to a message display asking whether or not to change the searched mail address of the other party. When each of the menu items “domain change” and “3 do not change” is selected and the determination button is operated, the central control unit 11 determines the selected item (steps J2 to J2). J4).

  If the menu item “3 do not change” is selected (YES in step J4), the flow of FIG. 14 is exited at this point, but if the menu item “2 domain change” is selected. (YES in step J3), the domain information storage unit M4 is searched based on the latest communication carrier of the other party acquired via the wireless communication network 4, and the corresponding domain information is read (step J11). A screen for inquiring whether or not to change the domain part to the domain information is displayed and output (step J12).

  FIG. 18 is a diagram showing a domain information change necessity inquiry screen, in which the domain information of the latest communication carrier read from the domain information storage unit M4 is displayed as a guide. When the “do not change” item is selected from the menu items on this inquiry screen and the enter button is operated (NO in step J13), the flow of FIG. 14 is exited, but the “change” item is selected. When the enter button is operated (YES in step J13), the domain part of the partner mail address is rewritten to the domain information read from the domain information storage unit M4 and changed (step J14). “0” is set in the “change flag” to reset it (step J15).

In addition, when the item “1 manual change” is selected on the above-described mail address change necessity inquiry screen (YES in step J2), the mail address input screen is displayed and output (step J5).
FIG. 19 is a diagram showing a mail address input screen. When a mail address is input by an input operation (YES in step J6), the corresponding domain is stored from the domain information storage unit M4 based on the latest communication carrier of the other party. Information is read (step J7), and it is determined whether or not it matches the input domain information (step J8). As a result, if the domain information matches, it is assumed that the mail address has been correctly input, and this input mail address is written in the “mail address” field of the other party to change it (step J9). Then, in order to indicate that the change has been made, “0” is set in the “change flag” of the other party to reset it (step J10).

  If domain information mismatch is detected (NO in step J8), a message to that effect is displayed to notify that there is a possibility of an input error (step J16). Here, when the continuation button in the input screen is operated to instruct the continuation of the mail address changing operation (YES in step J17), the process returns to the above-mentioned step J2 and the mail address changing process is continued. However, if the continuation instruction is not received (NO in step J17), the input mail address is written in the “mail address” item of the other party and the change is made (step J18). Since there is a high possibility that the domain is not correct, the “change flag” is kept “1”.

  FIG. 11 is a flowchart for explaining the outgoing call processing (step A13 in FIG. 6) in detail. The central control unit 11 checks whether voice outgoing or mail outgoing according to the outgoing operation (step F1). If there is, a call is made to the other party telephone number directly input from the operation unit 19 or to the other party telephone number in the address book storage unit M2 / incoming call history storage unit M3 (step F2). Here, it is checked whether or not the other party telephone number is stored in the address book storage unit M2 / incoming call history storage unit M3 (step F3), and if the other party telephone number is not stored, the process proceeds to step F11, Call processing is performed in response to the connection establishment. If the other party telephone number is stored in the address book storage unit M2 / incoming call history storage unit M3 (YES in step F3), the communication carrier is used together with the other party telephone number. An information acquisition request is transmitted and output (step F4).

  When the latest telecommunications carrier information transmitted in response to this acquisition request is received and obtained (YES in step F5), the telecommunications carrier information change process of FIG. 13 is executed (step F6), and then the process proceeds to step F7. It is checked whether the "change flag" of the other party is "1". If the carrier information is changed at the time of this outgoing call processing or the carrier information is changed at the time of the previous carrier information change processing, Is changed, the “change flag” is “1”. If the “change flag” is “0” (NO in step F7), the process proceeds to step F11 described above, and the call processing is performed. If “1”, the change notification screen shown in FIG. Then, after notifying that the communication carrier information has been changed (step F8), call processing is started in response to establishing a connection with the other party (step F9). Then, after the line with the other party is cut off, the process proceeds to the mail address changing process of FIG. 14 (step F10). In this case, you can know that the other carrier was changed before making a call, so if you ask for a new e-mail address during the call, enter the e-mail address in the e-mail address change process. Can be set.

  If it is mail transmission (NO in step F1), it is checked whether the other party's telephone number is stored in the address book storage unit M2 / incoming call history storage unit M3 in association with the other party's mail address (step F12). If not stored (NO in step F12), the process proceeds to step F19, and after sending an e-mail to the other e-mail address, this mail content is additionally stored in the mail storage unit M5 as a sent mail (step F20). ). If the other party telephone number is stored in address book storage unit M2 / incoming call history storage unit M3 (YES in step F12), a request for acquiring the carrier information is sent and output together with the other party telephone number (step F13). ). When the latest communication carrier information transmitted in response to this acquisition request is received and acquired (YES in step F14), the communication carrier information change process of FIG. 13 is executed (step F15).

  Then, the process proceeds to step F16, where it is checked whether or not the “change flag” of the other party is “1”. If the communication carrier information is changed during the mail transmission process this time or the communication carrier information previously performed. If the carrier information is changed during the change process, the “change flag” is “1”, but if the “change flag” remains “0” (NO in step F16), the above-described step The process goes to F19 to send an e-mail. If the “change flag” is “1”, the change notification screen for the communication carrier information shown in FIG. 16 is displayed and output, and the communication carrier information is changed. (Step F17) Then, the process proceeds to the mail address changing process of FIG. 14 (Step F18). When the mail address is changed to a new mail address, the mail is sent to the mail address after the change. (Step F19), the mail content is additionally stored in the mail storage unit M5 as sent mail (step F20).

  FIG. 12 is a flowchart for explaining the incoming call processing (step A15 in FIG. 6) in detail. The central control unit 11 checks whether the incoming call is a voice incoming call or a mail incoming call according to the incoming call (step G1). For example, the other party telephone number included in the incoming call signal is acquired, and an acquisition request for the carrier information is transmitted and output together with the other party telephone number (step G2). When the latest communication carrier information transmitted in response to this acquisition request is received and acquired (YES in step G3), the communication carrier information change process of FIG. 13 is executed (step G4). The incoming call information of this time is additionally stored in the incoming call history storage unit M3 (step G5), and the incoming melody is output to notify the incoming call (step G6). Then, the “change flag” of the other party is “1”. (Step G7), but if the carrier information is changed during the current incoming call process or if the carrier information is changed during a previous carrier information change process, The “change flag” is “1”.

  If the “change flag” is “0” (NO in step G7), call processing is started in response to establishing a connection with the other party (step G11). After the change notification screen shown in FIG. 16 is displayed and notified that the communication carrier information has been changed (step G8), call processing is started in response to establishment of connection with the other party (step G9). Then, after the line with the other party is cut off, the process proceeds to the mail address changing process of FIG. 14 (step G10). In this case, you can know that the carrier of the other party has been changed before making a call, so if you ask for a new e-mail address during the call, enter that e-mail address in the e-mail address change process. Can be set.

  If it is an incoming mail (NO in step G1), the incoming information of this time is additionally stored in the incoming call history storage unit M3 (step G12), and the incoming melody is output to notify the incoming call (step G13). This mail content is additionally stored in the mail storage unit M5 (step G14).

 As described above, in this embodiment, the central control unit 11 obtains the communication carrier information to which the other party telephone number currently belongs, and is associated with the other party telephone number in the address book storage unit M2 / incoming call history storage. By comparing with the telecommunications carrier information stored in the part M3, it is determined whether or not the telecommunications carrier has been changed, and when the telecommunications carrier has been changed, by notifying that it has been changed , It is possible to know that the telecommunications carrier to which the communication partner has subscribed has changed, and various measures can be taken according to the change, for example, a communication service unique to the telecommunications carrier that can be used with the other party. The charge discount can also be confirmed on the website of the carrier.

  The central control unit 11 makes a request for acquisition of communication carrier information from the wireless communication transmission / reception unit 14, and in response thereto, acquires the communication carrier information from the information management server 5 via the wireless communication network 4, thereby continuing the number. It is possible to acquire the carrier information by using the information management server 5 necessary for the system, and it is not necessary to newly construct a special facility and can be realized at a low cost.

  For example, once a week or once a month, the central control unit 11 obtains the communication carrier information every predetermined period, so that the user of the communication carrier of the other party's telephone number is obtained. It can be checked periodically whether or not it has been changed.

  When the central control unit 11 communicates with a communication partner (at the time of voice transmission / mail transmission / voice reception), the central control unit 11 acquires the communication carrier information of the other party's telephone number, thereby communicating with the communication partner. You can know that the carrier information has been changed. For example, you can ask the other party's e-mail address to be changed according to the carrier information during a call, or use it because they were the same carrier. It is possible to take various measures depending on the carrier of the other party's phone number, such as stopping the short message transmission that was possible and replacing it with voice transmission, or shortening the call time because the charge discount is no longer applied Become.

  The address book storage unit M2 / incoming call history storage unit M3 stores and manages the “telephone number” and “communication carrier” for each communication partner in association with each other, and also displays “change” as information regarding the change point of the communication carrier information. “Date and time” is stored and managed, and the partner information that has passed a predetermined period (for example, 5 days) from this “date and time of change” is specified as the batch change processing target, and the carrier information of the other party's phone number is acquired. By doing so, the frequency | count of acquiring communication carrier information via the wireless communication network 4 can be reduced. In other words, in general, carriers are not changed frequently, and when the time has not passed since the change, the confirmation of whether or not the carrier has been changed can be omitted. Can be reduced.

  The address book storage unit M2 / incoming call history storage unit M3 stores and manages the “telephone number” and “communication carrier” for each communication partner in association with each other, stores the “mail address” of the partner, and performs central control. When it is determined that the telecommunications carrier has been changed, the unit 11 notifies the user to change the “mail address” corresponding to the other party's telephone number, so that the address book storage unit according to the change of the telecommunications carrier It is possible to change the “mail address” in the M2 / incoming history storage unit M3.

  When it is determined that the telecommunications carrier has been changed, the central control unit 11 updates the “mail address” corresponding to the other party's telephone number according to the new telecommunications carrier after the change. According to the change, the “mail address” can be changed, and the burden on the user can be reduced. In this case, since the domain information of the mail address is often determined for each communication carrier, the domain information of the mail address can be updated according to the new communication carrier after the change.

  When displaying the contents of the address book storage unit M2, the address book screen is displayed with an icon of the other carrier, and when the carrier is changed, the change is displayed as an icon. Thus, it is possible to easily know which carrier has been changed by simply checking the address book screen.

  When displaying the contents of the address book storage unit M2, the address book screen compares the carrier information of the local phone number with the carrier information of the other party telephone number and displays an icon to indicate whether or not they are the same. If the telecommunications carrier has been changed, by displaying an icon indicating that the carrier has been changed, it is possible to check whether the telco has changed from the carrier of the local phone number due to the change of the other carrier. It can be easily confirmed. Since various communication services and charge discounts are often restricted between telephone numbers of the same carrier, whether or not the carriers are the same is important information.

  When the central control unit 11 communicates with a communication partner (voice transmission / mail transmission / voice reception), the central control unit 11 notifies that the communication carrier of the other party's telephone number has been changed, so that the other party's telephone number can be changed during communication. It is possible to know that the communication carrier information has been changed, and it is possible to take various measures as described above.

  In the embodiment described above, the information management server 5 is provided for each telecommunications carrier as a mechanism for realizing the number continuation system. However, an information management server that can be used jointly by each telecommunications carrier is provided. Any communication method may be used.

  Further, in the above-described embodiment, when the communication carrier of the other party telephone number is changed, when notifying that effect, the change notification screen of the communication carrier shown in FIG. 16 is displayed. This may be notified by outputting a voice message. Further, in the above-described embodiment, as the timing for notifying that the communication carrier of the other party telephone number has been changed, when executing the batch change process B that is started by the user operation, during communication with the communication partner ( (Voice call / Mail call / Voice call), but the carrier of the other party's phone number has been changed when the power is turned on or immediately after the voice call / mail call / voice call ends. You may make it alert | report.

In the embodiment described above, the telecommunications carrier information change process and the e-mail address change process are performed separately. However, the e-mail address domain information may be changed together with the telecommunications carrier information change. Good.
In addition, the present invention is not limited to the mobile phone device, and can be similarly applied to a communication terminal device such as a PDA, an electronic camera, an electronic wristwatch, and a music player.
