Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improving the operability of a telephone transfer function peculiar to a cellular radio telephone system.

[0002]

2. Description of the Related Art In the general telephone system of NTT, 198
March 2, 8th “TE” issued by Magazine House Co., Ltd.
As described in P174 of "LEPHONICA", when registering the transfer destination telephone number to activate the transfer telephone function, the transfer destination telephone number is pressed after pressing a specific code to make the system recognize that it is a registration operation. I was doing it by pressing a number.

In the case of a cellular radiotelephone system, for example, in the cellular radiotelephone system of the NTACS standard operated in Japan, a specific code is pushed, a telephone number of a transfer destination is pushed, and finally, an input is made. Press the send key to send the selected number to the system. Specifically, the procedure is as follows.

Registration activation of immediate transfer function ··· * 75 + transfer destination telephone number + call key Registration activation of transfer function only during busy ··· * 74 + transfer destination telephone number + call key

[0005]

In the above prior art, the user of the cellular radio telephone has to input a specific code for registering (activating) the transfer destination telephone number from the keypad. I had to remember it or write it down in a notebook. On the other hand, there is also a method of storing the telephone transfer function activation code in the speed dial memory using non-volatile memory and calling it at startup, but even in this case, if you continue to enter the telephone number, the called code will be erased. Since the processing peculiar to the cellular radiotelephone is carried out, the call transfer function activation code and the transfer destination telephone number had to be input in the end.

An object of the present invention is to add a specific code for activating a telephone transfer function to the head of the input telephone number by pressing a specific key combination after inputting a transfer destination telephone number, It is to improve the operability by omitting the input of the specific code.

Another object of the present invention is to change the code on the system side of a cellular radio telephone system or to expand its function by enabling the change of a specific code added by pressing a specific key or key combination. It is to be able to cope easily.

[0008]

In order to achieve the above object, a specific code is stored in a non-volatile memory by using a microprocessor, and a specific code is called by a key operation from a keypad to input a telephone call. The number can be added to the beginning.

In order to achieve the above-mentioned other object, the specific code in the non-volatile memory can be changed.

[0010]

The key input is controlled by the microprocessor. When there is a key input, the microprocessor activates the function assigned to it. If the entered key calls a specific code for activating the telephone transfer function, the specific code stored in the non-volatile memory is called and added to the beginning of the entered telephone number, A comment indicating that the specific code has been called is displayed, and the call waits. In the cellular radio telephone system, the number entered by pressing the call key after this is sent to the system side.

Further, by making it possible to change the specific code in the non-volatile memory, it is possible to easily deal with the code change and the function expansion by the cellular radio telephone system.
