Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a calling number storage and display method for a car phone.
In particular, the present invention relates to a caller number storage/display method that stores a caller number and displays the caller number based on a request from a car phone subscriber on the receiving side.

[Conventional technology]

Traditionally, this type of caller ID has not been stored.
Regarding the display of the caller's number, the calling party's number is displayed on the called car phone only while the calling phone and the called car phone are connected and talking.

[Problem that the invention seeks to solve]

The display of the calling number in the conventional car telephone described above is limited to the case where the caller and the called car phone subscriber are talking. However, because car phones are mobile by nature, if you go outside of the service area, or if you are in a place where the signal strength is poor even within the service area, you may not be able to connect even if you try to receive a call from the car phone exchange to your car phone. . Further, if the car phone is turned off, or if the car phone subscriber is away from the vehicle for various reasons, it is not possible to respond to incoming calls.

Since such car phone users are usually more socially important people or people who use them for business than general subscribers, if they are unable to receive or answer calls due to the above-mentioned conditions, they may not be able to deal with an emergency situation. Or it may have a negative impact on business. That is, conventional car telephones have the disadvantage that there is no way to find out from whom (caller number) a call is about to be received or if a call has been received.

SUMMARY OF THE INVENTION An object of the present invention is to provide a system for storing and displaying a calling number for a car phone, which allows the caller to be identified even when the user is absent or the car phone's power switch is turned off.

[Means for solving problems]

The calling number storage/display method for a car telephone according to the present invention is provided with a calling number information display device in a car phone, and a calling number information storage device in a car telephone exchange that accommodates subscribers of the car phone. When the mobile telephone exchange recognizes a call accessing a person, the telephone number of the caller is stored in the calling number information storage device, and the mobile telephone exchange recognizes that the mobile telephone subscriber is located within the service area of the mobile telephone exchange. When the caller number information is requested by the mobile phone subscriber, the car exchange directly sends the stored caller number to the car phone and displays it on the caller number information display device. If you are located in a service area other than the service area of the automobile exchange and request the calling number information, the automobile exchange in charge of the other service area will transmit the information via the relay network. accesses the car exchange that accommodates the car telephone subscriber, requests the caller number information stored in the car exchange to be transferred to the receiving car exchange, and transfers the calling number information from the receiver car exchange to the car exchange. It is configured to be sent to the car telephone and displayed on the calling number information display device.
