It includes.

The handset 78 is connected to one end of the modem 73.

Meanwhile, referring to the operation of the conventional telephone system as described above, first, when the telephone system 74 is set up, the microcomputer 75 receives a ring signal from the key panel unit 76 or the ring detect unit 72 in a standby state. Determine if you can. The microcomputer 75 proceeds to the call mode when the reception signal for detecting the detection of the ring signal is input from the ring detect unit 72 to control the function of the modem 73. That is, when the signal interface unit 71 interfaces the call signal input through the external communication network 70 and inputs it to the modem 73, the modem 73 demodulates the input call signal and amplifies the signal to a predetermined level. Enter (78). Then, when the user makes a call with the handset 78, the call signal is processed through the modem 73, and then to the external telephone 79 via the signal interface unit 71 and the communication network 70. Send to execute normal call function. In this case, a voice signal may be input through the speakerphone 77 according to the user's selection.

However, since the conventional telephone system as described above does not have any means for informing the call volume and the charging state according to the telephone call, it is not possible to integrate and manage individual call information, thereby resulting in inefficiency in call management of the telephone system. There was this.

In addition, the conventional telephone system as described above can not know exactly the information on the telephone call history, and also to receive the personal call records from the external service provider for manual management of the call, so that the security of the telephone history accordingly There was a problem that it lacked.

Accordingly, the present invention has been invented to solve the above problems, by having an IC card reader in the telephone system to record the personal call information on the individual IC card when making a phone call, it is possible to accurately manage the phone usage history for each individual Therefore, the object of the present invention is to provide a call system for storing call information using an IC card and a method of controlling the same.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 2, the telephone system of the present invention has a signal interface unit 2 for interfacing a call signal of an external caller input via a key phone 1, and a call input through the signal interface unit 2; Ring detection unit 3 for detecting a ring signal in the signal and ringing a bell (not shown), and a predetermined signal processing, for example, a modem for modulating / demodulating and amplifying a call signal input / output through the signal interface unit 2 ( 4), a microcomputer 6 which generally controls the functions of the telephone system 5 including the functions of the modem 4, and a microcomputer 6 which inputs a user's control command signal or dialing signal. Reads the IC card 8 inserted into the key panel unit 7 and one end of the microcomputer 6, and stores individual call information in the IC card 8 according to the call management control signal of the microcomputer 6; The IC card reader 9 is included.

In addition, a handset 10 is connected to one end of the modem 4, and an LCD panel 11 for displaying an operating state of the internal character by letters or numbers is connected to one end of the microcomputer 6.

Next, a control method applied to the system of the present invention as described above will be described.

The method of the present invention proceeds from the initial state S1 to the IC card input determination step S2 as shown in Fig. 3 to determine whether the current IC card is inserted. As a result of the determination during the IC card input determination step S2, if the IC card is not inserted, the process returns to the previous step and repeats the loop. However, if it is determined during the IC card input determination step (S2) that the current IC card is inserted, the process proceeds to the authentication confirmation request step (S3) and transmits the IC card user information to the key phone to request call use authentication.

In addition, after the authentication confirmation request step (S3), the process proceeds to the call use authentication determination step (S4) to determine whether the call use authentication signal of the IC card user is input from the current key phone system. At this time, if it is determined during the call use authentication determination step S4 that the call use authentication signal of the IC card user is not input from the key phone system, the process returns to the previous step S3 and repeats the loop. However, if the call use authentication signal of the IC card user is input from the key phone system as a result of the determination during the call use authentication determination step (S4), the call record checking step (S5) proceeds and the IC card user makes a desired call. The phone system checks this and stores the call history information for each individual.

Then, after the call recording checking step (S5), it proceeds to the call termination determination step (S6) to determine whether the call is terminated. At this time, if the call of the current IC card user is not terminated as determined in the call termination determination step (S6), the process returns to the previous step (S5) and repeats the loop. However, if the current IC card user's call is terminated as a result of the call termination determination step (S6), the call history storage step (S7) is received to receive the call history information of the IC card user currently checked in the keyphone system. Save to IC card and exit.

In other words, when the telephone system 5 is set up, the microcomputer 6 determines whether a signal for confirming the insertion of the IC card 8 is input from the IC card reader 9 in the standby state. When 8) is inserted, the microcomputer 6 recognizes this by the IC card recognition processing task and transmits a setup request message (SETUP REQUEST MESSAGE) to the key phone system 1 through the signal interface unit 2. In addition, after receiving an ALERT INDICATION signal through the signal interface unit 2 from the key phone system 1, the receiver receives a SETUP CONFIRM to allocate a channel. At this time, the key phone system 1 checks and stores the call history until the end of the call of the current IC card holder by executing the UASGE INFORMATION TASK after receiving the ALERT REQUEST signal.

On the other hand, the microcomputer 6 of the telephone system 5 displays this fact on the LCD panel 11 as a channel is allocated from the key phone 1. Then, the user of the current IC card (8) inputs the phone number of the counterpart that he / she wants to talk through the key panel unit (7). Then, the microcomputer 6 recognizes this and generates a ring signal through the ring detec unit 3 and transmits the ring signal to the other party's wired telephone 13 via the key phone 1 to which the channel is allocated and the external communication network 12. When the call signal is input to the signal interface unit 2 through the call processing process, the signal interface unit 2 interfaces the call signal input through the external communication network 12 to the modem 4. Let's do it. Then, the modem 4 demodulates the input call signal, amplifies it to a certain level, inputs it to the handset 10, and the user of the IC card 8 carries out the normal call with the handset 10. .

At this time, when the user of the IC card 8 ends the call, the microcomputer 6 sends a disconnect request signal to the key phone 1 to notify the end of the call. Then, the key phone 1 transmits the call history information signal used by the user of the current IC card 8 to the microcomputer 6 of the telephone system 5, and thus the microcomputer 6 inputs the call history information. The signal is stored in the IC card 8 via the IC card reader 9. The microcomputer 6 terminates the call after receiving the release indication signal from the key phone 1.

Then, in order to obtain the information contained in the IC card 8, the holder of the IC card 8 reads it when passing through, for example, the IC card reader 9 installed at a specific location, and stores it in a comprehensive management block. Can be integrated management.

As described above, the present invention is provided with an IC card reader in the telephone system to record personal call information on an individual IC card during a telephone call, so that the telephone usage history can be accurately managed for each individual. It has the advantage of maximizing efficiency.

In addition, according to the present invention, since the call-related information of the telephone system is precisely recorded and managed, the security of the telephone system is also significantly increased.
