1 shows an ISDN telephone device according to an embodiment of the present invention.

In FIG. 1, the same components as those of the conventional example shown in FIG. 2 are designated by the same reference numerals. Reference numeral 1 denotes a line I / F (interface) unit connected to the network, and a switch unit 2
, And the codec section 3 and the data I / F section 4 are connected to the switch section 2. The voice circuit 5 connected to the codec unit 3 is connected to a receiver 6, a transmitter 7 and an I / O controller 8 in a handset for making a call. A numeric keypad 9 and a ringer 10 are connected to the I / O controller 8. The central processing unit 20 is connected to the LCD 12 and is connected to each of the above parts to control the entire device.

Further, a plurality of IC card input / output units 22 _a1 , 22 _a2 , ..., 22 _an are connected to the IC card control unit 21 connected to the central processing unit 20.

In this embodiment, the IC card is registered (stored).

Next, when receiving a call, the central processing unit 2
From 0, the user / user information is sent to the IC card control unit 21. The IC card control unit 21 determines which IC card the user data should be written to, based on the subaddress, and the corresponding IC card input / output units 22 _a1 and 22 a.
Send user-user information to _a2 , ..., 22 _an . In the IC card input / output units 21 _a1 , 21 _a2, ..., 21 _an , the supplied user data is written in the IC card. For example, if the call setup message from the other party includes a user / user information element and the content is user data such as a message, it is registered in the corresponding IC card.

At the time of calling, under the control of the central processing unit 20, the IC card control unit 21 reads the user data stored in the designated IC card and sends it to the central processing unit 20 to set the call. A message to the partner terminal can be sent to the user / user information of the message. Further, at this time, since the user data is managed by the IC card, different user data can be dealt with individually.

At the time of call transfer (or transfer during communication), the IC card control unit 21 takes out user data in the specified IC card at the request from the central processing unit 20 and sends it to the central processing unit 20. It is possible to superimpose the user data registered in the IC card on the user / user information of the call (or response) message returned when an incoming call arrives to notify the caller side of the information regarding the transfer. Further, at this time, since the user data is managed by the IC card, it is possible to deal with the different user data. In this case, the central processing unit 20 can also specify the IC card from the calling number from the other party or the user / user information.

At the time of an incoming call in the absence mode, user data such as a message to be sent to the other party can be transmitted to the calling side terminal during the absence as in the transfer.

In this way, it is possible to manage the user / user information at one time by using each IC card used for each user in one telephone device.

Further, by simply registering the IC card in another terminal (ISDN telephone device), the user data such as the message contents of the user can be used anywhere.

Although the IC card input / output device is used in the above embodiment, other devices such as an electronic notebook can be used to change, update or refer to user data.

[0023]

As is apparent from the above embodiment, the present invention has an effect that the user / user information of a plurality of users can be managed at a time by using the IC card for each user.
