A radio communication network system provides a method of managing radio communication base stations and mobile terminals for accomplishing an access to the Internet from a mobile terminal and communications between mobile terminals. A base station management terminal, radio communication base stations, and mobile terminals reference their communication path information created by exchanging their adjacent terminal information and communication path information to ensure their respective communication paths to other terminals. Even if two mobile terminals cannot communicate due to their radiowaves failing to arrive at their destinations, the mobile terminals can provide a communication path for making communications therebetween through a communication line, the radio communication base station, and the base station management terminal.
