I end up. In particular, there is a need for a service that allows multiple subscribers to use the same dedicated telephone (12) and to accept incoming calls from a subscriber number that has been discontinued by specifying a specific time zone (1).

[Means for solving R problem]

The IC card telephone system of the present invention includes an IC card that stores subscriber identification information for identifying a subscriber and time information for specifying a connection time zone, and an IC card that stores the subscriber identification information and the time information from the IC card. a terminal for reading the subscriber identification information and the time information from the terminal to an exchange; a data transmitting/receiving means for receiving identification information and time information or transmitting connection instruction information to the terminal; and a storage means for previously storing the time information corresponding to the subscriber identification information using a predetermined number. and when the exchange detects an incoming call to the terminal, activates the storage means 1.
, 2. The time information is referred to using the subscriber identification information, and the calling party is controlled to connect to the terminal based on the instruction information.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Referring to FIG. 1, which shows one embodiment of the present invention, the exchanges are connected via data lines 8 to a control center that centralizes control information, and one of a plurality of exchanges is shown. Normally, the center is commonly used in the same service area. The exchange includes an IC card 1, a, which stores subscriber telephone number information and time information of permitted connection hours.

A dedicated telephone 2 and a normal general telephone I! read this information from 1-b. 3, a register 5 connected to the communication path switch 4 and receiving information read by the dedicated telephone 2, and identifying whether or not the dedicated telephone 2 is present from the housing position information. It includes a storage device 6 and a central control device 7. The controller 1-roll center has a data transmitting/receiving section that receives subscriber telephone number information and time information from the exchange 4 via the data line 8, or sends connection instruction information to the dedicated telephone 2, and an The system includes a storage device 10 in which time information is stored in advance in correspondence with subscriber telephone number information, and a central control section 11.

Next, two operations will be explained. In the registration operation, first, I C
The holder of the power card 1a inputs in advance the subscriber telephone number information assigned to him/her and the time period during which incoming calls are allowed, into the HC card 1a using an input means such as the Z key. , in the case of 2, the time period is 1 hour and j-5, for example, 10.00
- If you specify something like -12:00 and add # after the time zone, it indicates every day, and if you do not add R, it indicates 1: that the time information is valid only on the day it was input. This information can be changed at any time as necessary. When the dedicated telephone 2 makes a call Lfs, the central control device 7 identifies the dedicated telephone 2 for IC card 1 from its accommodation position information, selects the register 5 1 through the communication path switch 4, and selects 1. ~f'8 Receive the subscriber's telephone number and time information along with the special number. These information are transmitted to the central control device 7, and the central control device 7 refers to the storage device 6.
2 identifies that this special number indicates a registration operation and activates the 1-control center via data line 8; Started from the central control unit 7 h-'/:': Data transmitting/receiving section 9
receives the subscriber's telephone number and time information along with the special number 12, and stores the time information in the storage device 10 under the control of the central control unit 11 in correspondence with the subscriber's telephone number. When the storage operation is completed, a completion signal is sent to the central control unit 7 and the subscriber is notified from a generator (not shown).
Complete the registration operation. After completing the registration, remove the IC card] and a from the dedicated telephone 2.

Other subscribers using the dedicated telephone 2 can similarly register their desired time slots for incoming calls using their IC cards]-b. Furthermore, when the holder of the IC card registers from the mobile phone 12 or another dedicated telephone, the contents stored in the storage device 10 of the mobile phone center can be updated through operations similar to those described in steps 1 to 1 above.

Also, if you want to delete all registered contents Lf', by dialing a predetermined special number indicating a deletion instruction, the central control unit 7 refers to the storage device 6, identifies it, and sends it to the data transmitting/receiving section 9. By transmitting the cancellation information, the central control unit 11 can activate the storage device 10 and delete the corresponding registration contents in the storage device 10.

Next, in the connection operation when a call is received from the general telephone 3 to the dedicated telephone 2 used by the holder of the IC card 1a,
When the central control unit W7 detects an incoming call, it refers to the storage device 6 and reads from the storage location information whether the incoming call is to the dedicated telephone 2 - If the incoming call is to the dedicated telephone 2, The central control unit 7 immediately activates the control center via the data line 8 and transmits the special number for searching the storage device 10 and the subscriber telephone number received from the general telephone 3 to the data transmitting/receiving section 9.

The data transmitting/receiving section 9 transmits this information to the central control section 11, and the central control section 11 refers to the storage device 10 and reads the registration status for this subscriber number. The central controller M11 refers to a clock (not shown), and when the incoming call is within the incoming time period, sends a connection permission signal to the central controller 7, and the central controller 7 connects the general @phone 3 and the dedicated phone. 2 through the communication path switch 4. If the incoming call is outside the incoming call time range, a connection disapproval signal is sent to the central control unit W7, and the central control unit 7 sends a message to the general telephone 3 from a notification means (not shown) such as an announcement machine. control to send out.

In this embodiment, an example has been explained in which the dedicated telephone 2 and the general telephone 3 are housed in the same exchange, but even if they are housed in different exchanges, the control center is activated in the exchange on the called side, and the dedicated telephone is connected. It is possible to identify the permissible time period and transmit connection instruction information to the originating side using a common line signaling method or the like.

〔Effect of the invention〕

As explained above, the present invention uses an IC card into which subscriber identification information and time information are input, and allows a plurality of subscribers to input these subscriber identification information and time information into the storage means of a control center from the same terminal in advance.
