Abstract

DC60 (21/05/40) Malfunction of the vibrator, a defective feature of typical portable terminal devices of the independent vibrator type, will be eliminated. The terminal communication system, portable communication, will consist of a portable communication terminal capable of communicating while moving with other communication terminals via radio communication with a base station, and peripheral equipment performing predefined operations via radio communication with the portable communication terminal. The portable communication terminal will transmit radio signals to peripheral equipment using a time-division multiplexing access system for signal exchange by encapsulating data onto the time slot in radio communication between the portable communication terminal and peripheral equipment, and using a time slot in a time band that excludes other time bands where the portable communication terminal is transmitting radio signals to the base station. Therefore, radio waves transmitted from the portable communication terminal to peripheral equipment are protected from interference by radio waves transmitted from the portable communication terminal to the base station. Malfunction of the vibrator, a defective feature of typical portable terminal devices of the independent vibrator type, will be eliminated. The terminal communication system, portable communication, will consist of... A portable communication device (PAC) is a device capable of communicating while moving with other communication devices, relying on radio wave communication with a base station and surrounding equipment, performing predefined actions. The PAC transmits radio signals to surrounding equipment using a time-division multiplexing system for signal exchange, encapsulating data onto the radio communication time slot between the PAC and surrounding equipment. The time slot used is in a time band excluded from other time bands where the PAC is transmitting radio signals to the base station. Therefore, radio waves transmitted from the PAC to surrounding equipment are protected from interference by radio waves transmitted from the PAC to the base station.
