<p>PROBLEM TO BE SOLVED: To provide a portable radio communication terminal system that requires no wired communication lines, enables communication even at a place at which the electric field strength of an antenna is weak, enables a 2-party speech and is capable of call transmission and reception by itself through a relay of other radio communication terminals. SOLUTION: The system consists of a 1st portable radio communication terminal 2 that conducts transmission and reception to/from an external terminal and of a 2nd portable radio communication terminal 3 that conducts transmission and reception to/from the 1st portable radio communication terminal. The 1st portable radio communication terminal 2 is provided with 1st and 2nd signal transmission sections 5, 9 that conduct transmission and reception to/from the external terminal and the 2nd portable radio communication terminal 3, 1st and 2nd signal reception sections 6, 10, voice and information input means 11, 12, a voice output section 13 and a display section 14. The 2nd portable radio communication terminal is provided with a signal transmission section 16 and a signal reception section 17 that send/receive a signal to/from the 1st portable radio communication terminal, a voice input section 22, a data entry means 17, a handwritten character input means 20, a voice output section 26 that outputs voice data and information in voice, and a display section 24 that displays the information. In this way, a highly useful portable radio communication terminal system is obtained.</p> |
