BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private telephone system, and more particularly, to a telephone system in which call transfer to a destination telephone is simplified.

[0002]

2. Description of the Related Art In a private telephone system in which telephone numbers are assigned to individuals, a conventional method of transferring a telephone number of an individual to a destination extension telephone (hereinafter simply referred to as a telephone) is performed by dialing in advance. In some cases, the telephone number of the telephone set is registered in a private branch exchange (PBX).

For example, the private telephone system shown in FIG. 6 will be described as an example. In this system, among a plurality of telephones 2n (n = 1, 2, ..., I) connected to the private branch exchange 1, the telephone of the telephone 2n is called. Move number to destination phone 2n '
When it is desired to transfer the call to (n ≠ n ′), it is necessary to register in advance in the private branch exchange 1 such that the telephone number of the telephone 2n is transferred to the destination telephone 2n ′ by dialing.

[0004]

However, in such a conventional call transfer system of the private telephone system, it is necessary to register the telephone number of the destination telephone in advance, so that the destination May be changed, or the transfer operation may not be possible if the destination telephone number is unknown. Further, if the user forgets to perform the dial operation, the call will be transferred to a place where there is no individual, and there is a problem that the private branch exchange cannot detect the forgetting.

[0005] In any case, according to the conventional system, when an individual is absent, it is possible to check whether the person is nearby, check the destination, or not to be in a place to contact in advance. In many cases, in the case of emergency contact, it sometimes took time to transfer the telephone.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a private telephone system capable of easily and reliably transferring a telephone call to a destination. To do.

[0007]

In order to achieve the above object, the invention according to claim 1 is an IC card having a transponder element for storing a telephone number assigned to an individual in a built-in memory, and the transponder element. And an extension telephone having a reading means for reading the telephone number data stored in the transponder element and the telephone number data read by the reading means.
With reference to the storage means for updating and registering the C card and the extension telephone that has accessed, and the registration data stored in the storage means, the telephone number is associated with the telephone number equal to the dial number sent from the calling side. And a private branch exchange having a transfer means for searching the extension telephone and transferring the call signal to the searched extension telephone.

[0008]

According to the present invention having the above structure, the transponder element of the IC card stores the telephone number assigned to the individual, that is, the telephone number of the extension telephone assigned to the individual in the built-in memory. I remember it in advance. Individuals own and carry such IC cards.
For example, when the IC card is brought close to the nearest extension telephone of the moving destination, the reading means of the extension telephone accesses the transponder element of the IC card and reads the telephone number data stored in the transponder element. The read telephone number data is sent to the private branch exchange and the IC
The card is registered in the storage means in association with the extension telephone that has accessed. At this time, the data of the existing extension telephone associated with the telephone number is deleted and updated to the data of the new extension telephone at the destination. Also, by bringing multiple IC cards closer to the extension telephone,
The telephone numbers of the plurality of IC cards are automatically registered in the private branch exchange. When the dialing number desired to be called is transmitted from the calling side, the transfer means refers to the registration data stored in the storage means and associates it with the telephone number equal to the dialed number sent from the calling side. The searched extension telephone is searched, and the ringing signal is transferred to the searched extension telephone. As a result, the call received by the original extension telephone is automatically transferred to the destination extension telephone.

At the same time, the identification number K'of the telephone 6n 'is registered in the telephone number N and the registration of the identification number K of the original telephone 6n is deleted, and the data is updated to the latest one (step S21). On the contrary, when the individual returns to the original place from the destination, if the IC card 7m is brought close to the original telephone 6n, the private branch exchange 5
Currently registered in the memory 20 (RAM) of the mobile phone 6n 'corresponding to the phone number N of the IC card 7m.
The identification number K ') of the original telephone 6n corresponding to the IC card 7m is registered. Further, when an individual moves from a place with the telephone 6n 'to a place with another telephone 6n ", by bringing the IC card 7m close to the telephone 6n",
The identification number of the telephone set registered in the memory 20 (RAM) of the private branch exchange 5 is updated from the identification number K'of the telephone set 6n 'to the identification number K "of the telephone set 6n".

After the data registration process is completed in step S21, when the telephone of the calling side recognizes that the telephone is dialed (step S22), the CPU 19 reads the dial number M (step S23), and the memory 20 (step S23). R
AM), the telephone 6n 'registered in the telephone number N (that is, M = N) equal to the dial number M is searched for, and the telephone 6 searched is searched.
The call signal is transferred to n'through the switch circuit network 18, and the telephone 6n 'is called (step S24). When an individual is taken off-hook by picking up the telephone 6n '(step S25), the switch network 18 connects the telephone 6n' to the calling telephone (step S2).
6). Even when the incoming call is transferred to the destination telephone 6n 'as described above, the original telephone 6n still has the calling function, and the telephone 6n can make a call.

Therefore, according to the present embodiment, the IC card 7m is constituted by the transponder element 10 and the IC card 7m is brought close to the destination telephone 6n '.
The telephone number N of the card 7m and the identification number K'of the telephone 6n 'are automatically registered in the private branch exchange 5, and the call made to the original telephone 6n is automatically transferred to the destination telephone 6n'. Therefore, it is not necessary to previously perform dial operation on the original telephone side before moving, and the IC card 7m carried by an individual can be brought close to the nearest telephone 6n 'of the moving destination. The incoming call is automatically transferred to the nearest telephone 6n ', which simplifies the work of transfer registration and improves the certainty of the transfer.

Further, the work of transferring a telephone due to the absence of an individual and the work of searching for the individual when the whereabouts are unknown are omitted.
Business efficiency is improved. In particular, when an individual is absent, the transfer is repeated to the telephones in a plurality of places, and a large load is applied to the processing on the private branch exchange side each time. Since the exchange 5 recognizes it and the destination telephone is clear, the processing operation of the private branch exchange 5 is simplified.

Further, in this embodiment, since the IC card 7m is composed of the transponder element 10, there is no fear of the IC card running out of battery.
