Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a wireless telephone.

<Outline of the Invention> The present invention provides a mobile station with a confirmation code transmission means and a fixed station with a confirmation code storage means and a confirmation code determination means so that the fixed station can store the mobile station confirmation code. The present invention provides a wireless telephone capable of adding or replacing a mobile station to a fixed station.

<Prior Art> Conventionally, a fixed station connected to a telephone line network by a subscriber line and one or a plurality of mobile stations are formed, and the mobile station wirelessly communicates with the fixed station. There is a so-called wireless telephone.

When making a call with such a mobile telephone, first, the confirmation code (password) from the mobile station is oscillated to the fixed station, and the confirmation code received at the fixed station side is from the mobile station. Only when the confirmation was made, the connection operation to the subscriber line was performed.

<Problems to be Solved by the Invention> By the way, in the conventional wireless telephone as described above, only one mobile station having a predetermined confirmation code can be connected to one fixed station. However, there is a problem that it is not possible to replace the fixed station with a mobile station having another confirmation code or add a mobile to the fixed station later.

<Means for Solving the Problems> In order to solve the above problems, the present invention compares the confirmation code transmitted from the mobile station to the fixed station with the confirmation code already stored in the storage means of the fixed station. In the wireless telephone that controls the connection to the subscriber line based on
The fixed station is provided with a storage means in which a unique confirmation code is stored in advance and a transmission control means for reading out the unique confirmation code stored in the storage means in response to the operation of a storage button and transmitting it to the fixed station. And a determination means for determining a new confirmation code when the confirmation code of the mobile station transmitted by the transmission control means does not match the confirmation code already stored in the storage means, and the storage means is placed in a storage standby state. Storage operation means and storage control means for storing the new confirmation code discriminated by the discrimination means in the storage means in the storage standby state of the storage means are provided.

<Operation> Therefore, when the storage means of the fixed station is put into the storage standby state by the operation of the storage operation means, when the unique confirmation code stored in the storage means is read out and transmitted by the transmission control means provided in the mobile station, The transmitted unique confirmation code is discriminated by the discrimination means provided in the fixed station,
When it is determined that it is a new confirmation code, it is stored in the storage means of the fixed station by the storage control means.

Then, the data discrimination circuit 12 sends only the confirmation code to the confirmation code determination circuit 13.

The confirmation code determination circuit 13 sends a read command signal to the read control circuit 14 based on the input of the confirmation code.

Then, the read control circuit 14 reads the confirmation code from the storage unit 7 and sends it to the confirmation code determination circuit 13.

The confirmation code judging circuit 13 is the data judging circuit 12
When the comparison code is compared with the stored verification code and it is determined that the two codes match, a matching signal is sent to the data discriminating circuit 12.

Then, the data discrimination circuit 12 sends a connection signal based on the line connection code to the line control unit 6 based on the input of the coincidence signal, and as a result, the line control unit 6 is connected to the subscriber line 2.

(3) Regarding dial operation, the dial button 18 may be pressed after the above-mentioned line connection operation.

Then, the data analysis circuit 27 causes the dial button 18 to
The error correction code is added to the dial code corresponding to, a dial code signal composed of (dial code + error correction code) is created and sent to the wireless transmission / reception section 23.

Then, the radio transmitter / receiver 23 frequency-modulates the carrier wave based on the dial code signal, and transmits the modulated wave from the antenna 24.

In the fixed station 1, the above-mentioned modulated signal is received by the antenna 5, demodulated into a dial code signal by the wireless transmission / reception unit 4, and sent to the data analysis circuit 11.

The data analysis circuit 11 corrects the error of the dial code signal and determines the dial code as the data discrimination circuit 12

As described above, the mobile station 16 can make a call via the fixed station 1.

As described above, according to the present invention, the confirmation code is transmitted from the mobile station 16 to the fixed station 1, and the confirmation code is stored in the fixed station 1. When the line connection operation is performed, the fixed station 1 transmits the confirmation code to the fixed station 1. Since it is possible to confirm whether or not the confirmation code is a previously stored confirmation code, only the mobile station can be the one of its own preference without changing the fixed station 1 which has been impossible in the past. Can be replaced with a mobile station having a different confirmation code, and a mobile station having a different confirmation code can be added later, which is highly practical.

Further, even when only the mobile station is replaced due to a failure or the like, it is possible to connect even those having different confirmation codes, which is very convenient.

<Effects of the Invention> As described above, the present invention is extremely simple in that the storage operation means provided in the fixed station is operated to put the storage means of the fixed station in the storage standby state and the storage button provided in the mobile station is operated. With a simple operation, a unique confirmation code stored in advance in the mobile station can be read, transmitted, and registered in the fixed station, and the addition of mobile stations can be easily performed with extremely simple operations. Since the confirmation code already stored in the fixed station is not registered and only the new confirmation code is registered, the capacity of the memory can be effectively used.
