| 摘要 |
This invention provides a base station radio apparatus, a mobile unit communication system, and a control method for a base station radio apparatus that suppress a deterioration in communication quality. Success rates can be monitored by monitoring outgoing/incoming calls and call connections, and control can be executed to detect a potential card for which a success rate declines and force the card to enter an ALM state. Thus, a deterioration in communication quality can be suppressed.
