METHOD FOR TALKING OVER VIA CELLULAR PHONES

摘要

The present invention relates to a call method of a terminal suitable for making a call between specific persons by encrypting a voice signal. In the related art, voice data transmitted from a fixed station to a terminal is also initially set up with a terminal in the fixed station. In the process of being encrypted by a predetermined encryption key value in the process is divided into unit lengths according to the DECT regulations and then transmitted to the terminal, when the encryption key value is exposed, there is a drawback that the security of the contents of the call is impossible, but in the present invention After the first encryption process using the encryption key value that only the other parties knows, the existing encryption process is performed. Send and receive The taps when the taps to track only the encryption key values to be extremely difficult to improve the above drawbacks.
