ABSTRACT:
In resource measurement device32, a measured value x of resource use condition is acquired in respect of the wireless resource to be monitored. Furthermore, in comparators34and35, the measured value x is compared with the call admission threshold value xAof service A or with the call admission threshold value xBof service B, respectively. Comparison result selector36then selects one or other of the comparison results of comparators34and35in accordance with the type or degree of priority of the service of the call requested, identified by service identifier33, and call admission control device31restricts new call admission in accordance with the selected comparison result. Thus, the call admission control method, communication system and base station device wherein deterioration of communication quality is suitably suppressed by call admission control in accordance with the service that is being utilized are provided in communication in which access is performed with shared resources.
