Digital radio telephone for a digital mobile radio communication system

Abstract

A digital radio telephone comprises a radio portion for receiving a radio signal modulated by an encoded digital signal including control information, for demodulating and outputting the encoded digital signal, a control signal processing portion for decoding the demodulated encoded digital signal to obtain the control information, a telephone number information detecting means for detecting whether the decoded control information includes mate telephone number information, a memory for storing the telephone number information, a time information management means for specifying an incoming time of the telephone number information to output a time information, and a memory management means for recording the telephone number information corresponding to the time information into the memory.

Problems solved by technology

Since the incoming redialing function in the conventional analog radio telephone constructed as explained above requires the DTMF receiver for detecting the telephone number information in addition to the construction for operating the telephone function itself, there is a problem that the conventional analog radio telephone construction is complicated.

Also, since the conventional analog radio telephone redials using the telephone number information stored only in the memory, it is difficult to provide an incoming redialing function having high-performance or multifunction in consideration of user service.
