Description

  The present invention relates to a mobile phone terminal, a telephone number change notification system, and a program, and more particularly to a processing technique for performing a telephone number change notification when a telephone number is changed.

  Conventionally, when a telephone number is changed due to replacement of a mobile phone terminal or the like, a user often notifies the change of the telephone number using e-mail or the like. In this case, the destination of the telephone number change notification is usually selected from the destinations registered in the address book in the mobile phone terminal. For this reason, when there are a large number of targets to which a telephone number change notification is to be sent, there is a problem that if the user notifies each target of the change individually, the time required for the work becomes long.

In order to solve such a problem, for example, in Patent Document 1, telephone number information before change and information on a destination to which a telephone number change notification is to be transmitted are registered in advance, and the telephone number is changed based on the registered contents. A technique for automatically sending notifications is described.
JP 2003-60778 A

  By the way, in the conventional technique as described above, the destination of the telephone number change notification is limited to the destination registered in the user address book. Therefore, there has been a problem that a telephone number change notification cannot be made to a partner who is not registered in the user's address book. In this case, a phone number change notification by the user is sent to a person who knows only the old phone number before the user's change and whose contact information is not registered in the user's address book. It will not be possible. Therefore, there is a problem that such a user cannot contact the user who has changed the telephone number.

  In addition, as in the technique described in Patent Document 1, even if the destination information as the transmission destination of the telephone number change notification is registered in advance, it is not possible to reduce the labor involved in the transmission work of the telephone number change notification. was there.

  Such a problem can also be solved by using a telephone number notification service provided by a mobile phone carrier. If this service is used, a mail notifying the new telephone number is sent to the mail address registered in the address book used when using the old telephone number. However, in this case, support by the carrier is indispensable, and the problem that the telephone number change notification is not transmitted to the other party who is not registered in the address book remains unsolved.

  SUMMARY An advantage of some aspects of the invention is that a telephone number change notification can be automatically transmitted without requiring support by a carrier and without troublesome users.

Output to.

  Next, with reference to FIGS. 3 and 4, an example of processing when a telephone number change notification is transmitted triggered by an incoming call will be described. FIG. 3 is a flowchart showing operations in the mobile phone terminal 100 used by the user B who has changed the telephone number and the mobile phone terminal 100 used by the user A who makes a call to the user B. Here, a case where user A makes a call to an old telephone number of user B will be described as an example.

  First, as shown in FIG. 4A, the user A displays 090-1000-0001, which is the old telephone number Tn1 of the user B, on the display unit 9, and makes a call to this number. As a result, the phone number of user B is called from the mobile phone terminal 100 of user A (step S1 in FIG. 3), and the call is received by the mobile phone terminal 100 of user B (step S2). A line is connected between the mobile phone terminals 100 (step S3). Then, a call is made between both users through the connected line (step S4).

  Next, in the mobile phone terminal 100 of the user B, it is determined whether or not the caller is a fixed phone (step S5). If the call is a fixed phone, the process ends. Here, since the phone A used by the user A is the mobile phone terminal 100, “NO” is selected. Then, it is determined whether or not the telephone number used for the call is an old telephone number (step S6). If the telephone number used for the call is a new telephone number, the process ends. .

  When the telephone number in the incoming call is a new telephone number, the call is received by the transmission / reception processing unit 4a without going through the internal transfer unit 4c having an interface with the second SIM card 12. That is, the telephone number used for making a call is not an old telephone number. Therefore, in such a case, “NO” is selected in step S6.

  In the example shown in FIG. 4A, the telephone number used for the call is “090-1000-0001”, which is the old telephone number of the user B, so “YES” is selected. Next, in the mobile phone terminal 100 of the user B, the call is transferred from the internal transfer unit 4c (see FIG. 2) that has received the call to the transmission / reception processing unit 4a through the single line I / F unit 4b (step S7). Then, in the message generation unit 14a (see FIG. 2) in the SMS providing unit 14, a phone number change notification including the old phone number information and the new phone number information is generated (step S8), and the phone number change notification is generated. Is transmitted to the call originator (step S9).

  FIG. 4B shows an example of a telephone number change notification. In FIG. 4 (b), under the message “The phone number has been changed”, the information of the old phone number Tn1 is changed to “old number: 090-1000-0001” and the new phone number Tn2. The information is described as “new number: 090-1000-0002”.

  In the mobile phone terminal 100 of the user A who is the call originator, it is determined whether or not the telephone is in use when the telephone number change notification is transmitted (step S10), and the power of the telephone is turned off. If the telephone is not in use, for example, the process ends here. If the telephone is in use, a telephone number change notification is received (step S11). Then, it is determined whether or not the telephone number used for the call in step S1 matches the number described as “old number (“ old number ”in the example of FIG. 4)” in the telephone number change notification. (Step S12).

  If the numbers do not match, the process ends. According to the example shown in FIG. 4A, the telephone number used for the call is the old telephone number Tn1 of the user B, which matches the telephone number described as “old number” in the telephone number change notification. Therefore, “YES” is selected in step S12 of FIG. Then, based on the control of the control unit 1, the telephone number registered as the contact information of the user B in the address book 10 a in the mobile phone terminal 100 of the user A is “new” described in the telephone number change notification. The number is overwritten with “number (“ new number ”in the example of FIG. 4)” (step S13).

  That is, in the mobile phone terminal 100 of the caller (user A in this case), whether the contents described in the address book 10a are updated using the information described as “old telephone number” in the telephone number change notification as a key. Judgment of whether or not. That is, on the transmission side of the telephone number change notification (here, user B), an old telephone number is described as information used as a key.

  FIG. 4C shows registration information of user B in the address book 10a of user A before receiving the telephone number change notification, and the old telephone number of user B is shown as the telephone number of user B in the telephone number column. It is indicated that “090-1000-0001”, which is Tn1, is registered. As a result of making a call using this telephone number, a telephone number change notification is transmitted from the user B, and the process of step S13 in FIG. 3 is performed, so that the address book 10a of the user A is shown in FIG. It is updated to the contents. That is, the telephone number of user B is rewritten to “090-1000-0002”, which is the new telephone number Tn2 of user B.

  Next, an example of processing when a telephone number change notification is transmitted triggered by reception of a short message will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart showing operations in the mobile phone terminal 100 used by the user B who has changed the telephone number and the mobile phone terminal 100 used by the user A who sends a short message to the user B. Here, a case will be described as an example where user A sends a short message addressed to user B's old telephone number to user B.

First, when a short message is transmitted from the user A to the user B who has changed the telephone number (step S21), the short message is received at the mobile phone terminal 100 of the user B (step S22).

  Then, in the mobile phone terminal 100 of the user B, it is determined whether or not the destination of the received short message is an old phone number (step S23), and if the destination of the short message is a new phone number The process is terminated. When the destination of the short message is a new telephone number, the message is received through the transmission / reception processing unit 4a without going through the internal transfer unit 4c having an interface with the second SIM card 12. That is, since the destination of the short message is not an old telephone number, “NO” is selected in step S23.

  Here, since it is assumed that the old telephone number of the user B is set as the destination of the short message transmitted from the user A, the short message is transmitted from the civil war forwarding unit 4a to the single line I / F unit 4b. Is transferred to the message storage unit 15a. Accordingly, it is determined that the destination of the short message is the old telephone number, and “YES” is selected in step S23.

  Subsequently, in the message generating unit 14a (see FIG. 2) in the SMS providing unit 14, a telephone number change notification including the old telephone number information and the new telephone number information is generated (step S24). At this time, the message generation unit 14a sets the transmission source in the short message stored in the message storage unit 15a as the transmission destination of the telephone number change notification. Then, the telephone number change notification is transmitted to the transmission source of the short message (step S25).

  When the mobile phone terminal 100 of the user A who is the transmission source of the short message receives the telephone number change notification (step S26), the number described as “the old number” in the telephone number change notification is transmitted in step S21. It is determined whether or not it matches the destination number in the short message (step S27).

  If the numbers do not match, the process ends. In this example, since user A sends a short message specifying the old telephone number of user B as the destination, the number described as “old number” in the telephone number change notification and the telephone at the destination of the short message The number matches. Accordingly, “YES” is selected in step S27.

  Next, based on the control of the control unit 1, the telephone number registered as the contact of the user B in the address book 10 a in the mobile phone terminal 100 of the user A is “new number” in the telephone number change notification. Is overwritten with the number described as (step S28).

  According to the above-described embodiment, the mobile phone terminal 100 used by the user who has changed the phone number is triggered by the reception of an incoming call to the old phone number or a short message addressed to the old phone number as a trigger. Change notifications are automatically generated. Then, the telephone number change notification is transmitted to the caller of the telephone or the sender of the short message. This eliminates the need for the user who has changed the telephone number to actively notify the telephone number change.

  That is, it is possible to save the user from generating a telephone number change notification or selecting a transmission destination of the telephone number change notification.

  In addition, according to the above-described embodiment, a telephone number change notification is automatically sent to a party who has made a call to an old telephone number or a person who has sent a short message destined for the old telephone number. Sent. Accordingly, a telephone number change notification is transmitted to a user who is not registered in the address book of the user who has changed the telephone number.

  In addition, according to the above-described embodiment, the telephone number change notification is automatically transmitted without intervention of a carrier that provides a mobile phone communication service, an operator, or the like.

  Further, according to the above-described embodiment, in the mobile phone terminal 100 that has received the telephone number change notification, the telephone number of the transmission source user registered in the address book 10a is automatically new. Rewritten with a phone number. When the telephone number change notification is manually made by the user or when the telephone number notification is transmitted by the carrier service, the work of updating the registered contents of the address book 10a on the side receiving the telephone number change notification However, it is possible to save such trouble.

  The series of processes described above can be executed by hardware, or can be executed by software. When a series of processing is executed by software, it is possible to execute various functions by installing a computer in which a program constituting the software is incorporated in dedicated hardware, or by installing various programs.
