Resource measurement deviceacquires a measured value x of the resource use condition in transmitting/receiving sectionin respect of the wireless resource that is the subject of monitoring. Also, correction value calculation devicecalculates a correction value in accordance with the number of packet users at transmitting/receiving sectionand adjustment deviceadjusts the call acceptance threshold value xusing the correction value, so as to obtain a corrected threshold value x'. Comparatorthen compares the measured value of the resource use condition x and the corrected threshold value x&#x2032; and outputs the comparison result to call acceptance control device. If x&#x2267;x&#x2032;, call acceptance control devicerestricts acceptance of new calls. Thus, the call acceptance control method, mobile communication system and base station device whereby deterioration of communication quality is suppressed irrespective of the switching system are provided in mobile communication in which multiple access is performed with shared wireless resources.
