TRAVELLING OBJECT COMMUNICATION SYSTEM

摘要

PURPOSE:To attain processing for lots of calls smoothly even in a service area with high communication traffic density by setting a prescribed number of fixed radio stations sending a control signal according to its own identification information possessed by each fixed radio station. CONSTITUTION:Plural fixed radio stations shown in broken lines are installed at a same location and a control signal transmission control section limits fixed radio stations able to send a control signal to, e.g. fixed radio stations 1, 2 according to identification information of fixed radio stations included in the control signal sent from a control signal detection receiver. Then the fixed radio station 2 sends a control signal after a prescribed time after the transmission of a call reply signal of the fixed radio station 1. Thus, no signal collision takes place between the fixed radio stations 1 and 2 and a portable telephone set receives a call reply signal from a fixed radio station without radio interference in an excellent way. Thus, the system in which simultaneous talking with lots of portable telephone sets is attained in a service area with high communication traffic is established.
