RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system in which setup and call interruption of a radio communication terminal equipment connecting to a network via two-way incoming/outgoing narrow band radio channels and an outgoing broad band radio channel are conducted efficiently, the power consumption of a receiver of a broad band radio channel provided to the radio communication terminal equipment is reduced and the radio communication terminal equipment is made small. SOLUTION: A radio communication terminal equipment 5 sets a call with a narrow band radio base station 3 to set up a 2-way narrow band radio channel and makes setup request to a database 2 by using the 2-way narrow band radio channel and the database 2 accordingly makes setup request between the broad band radio base station 4 and a terminal equipment 5 to assign the outgoing broad band radio channel to the terminal equipment 5 and sets a call between the terminal equipment 5 and the database 2.
