Abstract

PROBLEM TO BE SOLVED: To enable a transmitter terminal to confirm the transmission of message data by displaying the message data acquired by transmitter terminal equipment, and then, transmitting these message data to a central control unit, which repeats and transfers these data to recipient terminal equipment, making the received message data displayed at the recipient terminal equipment to notify the user of the data. SOLUTION: Transmitter terminal equipment 1 requests the message data to a central control unit 3 by a number designated by the user and the central control unit 3 returns the message data. The transmitter terminal equipment 1 displays these message data and the user can confirm the message data to be transmitted. After the confirmation, the transmitter terminal equipment 1 transmits these message data to the central control unit 3. The central control unit 3 repeats these message data and transfers them to recipient terminal equipment 2. The recipient terminal equipment 2 displays the received message data to notify the user of the data.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to message data communication between terminal devices.

[0002]

2. Description of the Related Art An example of a conventional system will be described with reference to FIG. The terminal devices 1 and 2 each have a storage device therein,
It holds all of the message data used in the system. The caller terminal device 1 selects one of the message data and transmits it to the central control device 3, and the central control device 3 transfers the message data to the callee terminal device 2. The called party terminal device 2 displays the received message data and notifies the user. Another example of the conventional method will be described with reference to FIG. All message data used in the system is held in the central controller 3,
Each is given a number. The caller terminal device 1 transmits a number designating message data to the central control device 3. Central controller 3 selects predetermined message data from the received number and transmits it to called party terminal device 2. The called party terminal device 2 displays the received message data and notifies the user.

[0003]

Among the above-mentioned conventional systems, the former requires a large amount of storage device because the terminal device stores all message data used in the system. For this reason, the terminal device becomes large and expensive. In particular, this point is a disadvantage in a mobile terminal device required to be miniaturized. Among the conventional methods, in the latter, it is impossible to confirm the message data transmitted by the sender terminal device, and when the message data is changed by the central control device, message data different from the sender's intention is transmitted. There were drawbacks. The present invention eliminates these drawbacks of the conventional method, and enables the sender terminal to confirm the message data at the time of transmitting the message data, and to transmit the message data from the terminal device which does not require a large-capacity storage device. It is intended to provide a transmission method.

[0004]

In order to achieve the above object, the present invention holds all message data used in the system together with a number corresponding to a central control unit, and a sender terminal specifies a number. Message data from the central controller. After displaying the acquired message data, the sender terminal device transmits the message data to the central control device, and the central control device relays the message data and transfers the message data to the called terminal device. The called party terminal device displays the received message data and notifies the user.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
This will be described with reference to FIG. In FIG. 1, the central control unit 3
Has a storage device 4 in which all the message data used in the system are stored together with the corresponding numbers.
As the storage device, for example, a hard disk device, RA
M or ROM or the like is used. Sender terminal device 1
Requests the message data to the central control device 3 with the number designated by the user, and the central control device 3 returns the message data. The sender terminal device 1 displays this message data, and the user can confirm the message data to be transmitted. After confirmation, the sender terminal device 1
Transmits this message data to the central control device 3. The central control device 3 relays this message data and transfers it to the called party terminal device 2. The called party terminal device 2
The received message data is displayed to notify the user.

[0006]

According to the present invention, it is sufficient that the terminal device has a storage device for storing only one message data to be transmitted. For example, when 200 message data are used in the system, all the message data are stored. What is necessary is just to have 1/200 storage device when the data is held in the terminal device. Also, the message data itself transmitted by the sender terminal device can be displayed, and the message data intended by the user can be transmitted without error.
