A wireless line sharing network system enabling the charge of fees according to the use of a wireless communication network as well as reduction in capital invested by a communication carrier. A user terminal that subscribes to a communication carrier accesses a corresponding communication carrier network at a licensed radio frequency through a wireless base station (BS) and a control station ( 10 ). In response to a call connection request, a call acceptance controller ( 101 ) accepts the call and reserves bandwidth based on a radio bandwidth allocation pattern defined by contract and current use conditions. A bandwidth determination section ( 107 ) determines bandwidth for the call connection request using the call connection request, a call connection acknowledgement and a bandwidth table ( 106 ). A rate change controller ( 103 ) controls bandwidths for user terminals so that the currently used bandwidth of each communication carrier are kept within a predetermined range. An accounting controller ( 110 ) charges each communication carrier according to the radio bandwidth lease agreement.
