DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.
This will be described with reference to the drawings. FIG. 1 shows a configuration according to an embodiment of the present invention, wherein 1 is a mobile phone on the transmitting side (hereinafter, the mobile phone 1 is referred to as the transmitting side phone), and 2 is a mobile phone on the receiving side. (Hereinafter, when the mobile phone 2 is referred to, it refers to a receiving-side telephone.) 3 is a digital exchange that manages the mobile phones 1 and 2, 4 is communicable with the digital exchange 3, and each mobile phone 1 and 2 This is an information storage unit that records telephone numbers, names, and the like. The information storage unit 4 includes a table indicating a correspondence between a new telephone number and an old telephone number as shown in FIG. Nothing in the old telephone number indicates a new subscriber. This table contains
The telephone numbers of all the subscribers who subscribe to the mobile phone service network are stored. The stored order is, for example, the order of subscription or vice versa. The content stored in the information storage unit 4 is rewritten as needed by a management device (not shown). The management device constantly monitors the number of the new subscriber, the change of the number of the existing subscriber and the abolition of the number, and when there is a new subscriber, the new telephone number column T2,
To add the person's telephone number and change the existing subscriber's number, shift the old number to the old telephone number field T1 and enter the new number in the new telephone number field T1. In the case of abolition, the corresponding number is deleted from all columns.

Next, a method of notifying the change of the mobile phone number will be described with reference to the flowcharts of FIGS. The flowchart of FIG. 3 shows the process of the mobile phone 1. FIG. 4 shows processing of the mobile phone 2. FIG. 5 shows the processing of the exchange. Here, it is assumed that the mobile phone 2 has changed the telephone number. The number before the change of the mobile phone 2 is the first telephone number, and the number after the change is the second telephone number.

Assuming now that the mobile phone 1 has transmitted a connection request with the number (first telephone number) of the mobile phone 2 before the change (S101), the exchange 3 receives the connection request (S30).
1) Search the old telephone number column T1 of the information storage unit 4, and if the corresponding telephone number is hit, read the number (second telephone number) in the new telephone number column T2 on the same line, and The first telephone number is rewritten to the second telephone number and connected to the corresponding mobile phone 2 (S302). Then, a call request is transmitted to the mobile phone 2 (S303), and the telephone number of the mobile phone 1 is transmitted (S304).

The portable telephone 2 receives a call request from the exchange (S201), and subsequently receives the caller telephone number, and displays the number on the display of the own telephone (S202). At this time, the following message can be displayed at the same time. "Do you want to notify the caller who is displaying the new telephone number? Press the 1 key for YES. Press the 2 key for NO." If no display is made, immediately if one key is pressed (S203), a new telephone number is transmitted to the caller together with the specific signal (S203).
204). As the specific signal, a signal emitted from the * button of the mobile phone is used. The specific signal has a meaning of notifying the receiving side that the number transmitted together with the specific signal is the changed telephone number notification. Thereafter, a call is started (S205).

On the other hand, when the operator presses the key 2 (S203), no telephone number is transmitted. Therefore,
The mobile phone 1 makes a call without knowing the changed number of the mobile phone 2 (S206, S205). When the operator presses the 1 key in S203, the exchange 3 receives the specific signal from the mobile phone 2 (S305),
The specific signal is converted to a second specific signal, or the second signal transmitted at the same time as the specific signal without conversion is converted.
Is transmitted to the mobile phone 1 together with the telephone number (S306).

When the portable telephone 1 receives the specific signal and the second telephone number from the exchange 3 (S102), it temporarily stores it in a memory and starts a call (S103). When the call is terminated (S104), a confirmation message of approval for rewriting the temporarily stored second telephone number is displayed on the display of the own telephone (S105). The confirmation message is "The recipient's phone number is from △△△ ― △△ to ○○○ ―
It has been changed to ○○○○. Do you want to rewrite? " The caller sees this message and presses the 1 key if he / she wants to rewrite, and presses the 2 key if he / she does not want to rewrite (S106). When the first key is pressed, the contents of the memory are changed from the first telephone number to the second telephone number (S107). When the key 2 is pressed, the telephone number is not changed and remains at the original telephone number. Also, the temporarily stored contents are deleted.

As described above, according to the embodiment of the present invention,
