Description

Calling identity delivery system with wireless transmission function {Calling identity delivery system containing wireless transceiver}

A caller information display (CID) device is connected to the telephone line 110, and transmits and receives caller information related data in the on-hook or off-hook state of the phone 120, the caller's telephone number, name, date of call , A time, etc. are received through the data transmission / reception circuit 102 and displayed on the display device 101, and the above information (telephone number, name, date, time) can be stored in the memory 105. The stored information can be retrieved by the key input device 104 and can be called back to the stored telephone number. 1 shows a caller information display (CID) device 100 connected to a telephone 120 by wire.

The present invention implements a caller information display (CID) device, in order to make it easy for a user to check caller information (phone number, name, date, time), wirelessly with the fixed (wired) device (200, 300) It consists of mobile (wireless) devices (400, 500) to communicate, so that it can be installed freely in a desired place.

Conventional caller information display (CID) device 100 is wired to the phone, or is implemented integrally to a wired or wireless telephone, the screen of the display device 101 is not large, it is difficult for the user to see the screen from a distance, the phone or There is an inconvenience to go to the caller information display (CID) device 100 to check.

The main purpose of the present invention is to implement a Calling Identity Delivery (CID) device of a telephone system, comprising a fixed (wired) device connected to a telephone line, and a mobile (wireless) device that can be freely installed in a desired place. By connecting to each other, wireless communication, the caller information (phone number, name, date, time) is easy to see.

In order to achieve the above object, a fixed (wired) device 200 that adds a wireless transmission and reception function to a conventional caller information display (CID) device, or a fixed (wired) device having a function of transmitting and receiving caller information related data ( 300).

Configure a mobile (wireless) device 400, 500 that can communicate with the fixed (wired) device wirelessly to display (display) caller information (phone number, name, date, time) and install it where the user desires. do.

By interlocking the fixed (wired) device and the mobile (wireless) device by wireless communication, the present invention implements a caller information display (CID) device to be achieved.

An embodiment of the present invention will be described with reference to the accompanying drawings. Although the external caller information display (CID) device is connected to the telephone line 110 of the general telephone 120 in a wired manner, the same applies to the integrated caller information display (CID) device included in the wired / wireless telephone. It can be applied in a way.

FIG. 2 illustrates the addition of a wireless transmit / receive circuit 204 to a conventional caller information display (CID) device (FIG. 1), and processes caller information related data in an on-hook or off-hook state of the phone 120. By wirelessly communicating with the mobile (wireless) device 400 or 500 of FIG. 4 or 5, caller information (phone number, name, date, time) may be displayed on the display devices 401, 502.

3 is a simplified (wired) device connected to the telephone line 110 as much as possible, and operates in conjunction with the mobile (wireless) device 400 of FIG. 4 by wireless communication. The fixed (wired) device 300 of FIG. 3 has a function of transmitting and receiving caller information related data, and the mobile (wireless) device 400 of FIG. 4 processes caller information related data, and caller information (phone number and name). , Date and time) are displayed on the display device 401 and have a function of storing in the memory 405. The stored information can be retrieved by the key input device 404 and can be called back by the stored telephone number.

FIG. 5 is a simplified mobile (wireless) device, and interworkes with the fixed (wired) device 200 of FIG. 2 by wireless communication. Is displayed on the screen.

Several mobile (wireless) devices 400 and 500 may be connected to one fixed (wired) device 200 by wireless communication, and also several mobile (wired) devices 300 may be moved ( Wireless) device 400 may be used by wireless communication. Therefore, by installing mobile (wireless) devices 400 and 500 in various places, caller information (phone number, name, date, time) can be conveniently checked.

The wireless communication between the fixed (wired) device and the mobile (wireless) device may use radio wave (RF) communication or infrared communication. Radio wave (RF) communication method has a small impact on the obstacle, but there is a concern that the interference with the outside, the infrared communication method has a large impact on the obstacle, but has the advantage of preventing interference with the outside.

In constructing a caller information display (CID) device, caller information can be displayed (displayed) on a mobile (wireless) device, and mobile (wireless) devices can be installed in various places where necessary to easily check caller information. You don't have to go to your phone to check the caller information (phone number, name, date, time). Infrared communication can easily eliminate interference with the outside (for example, a neighboring house). When radio transmission is a radio wave (RF) communication method, the influence of obstacles (eg, walls, furniture) can be eliminated.
