MASTER AND SLAVE TELEPHONE SYSTEM IN PHS SYSTEM, AND RELAY SIDE SLAVE UNIT OF MASTER AND SLAVE TELEPHONE SYSTEM IN THE PHS SYSTEM, AND RELAYED SIDE SLAVE UNIT OF THE MASTER AND SLAVE TELEPHONE SYSTEM IN THE PHS SYSTEM

摘要

PROBLEM TO BE SOLVED: To cope with the relay operation of a radio wave causing large power consumption to relay the radio wave only during charging and also to concurrently use self-communication together with a radio wave relay. ;SOLUTION: This system consists of a relay side slave unit 2 which is provided with charge type power supply, a charge detecting means 49 which detects the state under charging of the power supply, relaying means 31 to 35 which relay communication in a household mode between a master unit 1 and a relayed side slave unit and a control circuit 43 that inhibits relay of communication by the means 31 to 35 when it is recognized not to be under charging, based on an output of the means 49, and the relayed side slave unit that is provided with a transmitting and receiving means which performs communication in the household mode with the master unit through the slave unit 2.;COPYRIGHT: (C)1999,JPO
