Abstract

PURPOSE: To attain mobile communication through the use of a small radio terminal equipment having a weak transmission power such as a portable radio equipment without installation of a relay station by using an automobile telephone radio terminal equipment so as to relay and send a signal sent from a small sized radio to a base station.
CONSTITUTION: A weak transmission signal is sent from a small sized radio terminal equipment 100 such as a portable telephone set. An automobile telephone radio terminal equipment 103 mounted on an automobile 102 passing in the vicinity of the small sized radio terminal equipment 100 receives a signal from the small sized radio terminal equipment 100 when a reproduction relay on/off switch 108 is closed except the operating state by the reproduction of the transmission signal from the other small sized radio terminal equipment and by talking by an automobile passenger, reproduces it and sends the reproduced signal to a base station 110. Then the transmission signal from the base station 110 is sent directly to the small sized radio terminal equipment 100. Thus, the mobile communication service by the small sized radio terminal equipment by using weak transmission power is attained without installation of the relay station.
