Abstract

　基準基地局と複数の基地局で構成されるサービスエリア内における無線同期方法であって、無線同期を実行する同期実施局が、当該同期実施基地局の無線モニター範囲内の基地局に対して無線モニターを実施し、前記無線モニターの結果に基づいて、前記サービスエリア内の基準基地局に同期していると共に、電波強度が高い基地局を同期対象候補基地局と選定し、基地局間通信を利用して、サービスエリア内の周辺基地局に対して前記同期対象候補基地局の無線モニター情報の提供を依頼し、前記周辺基地局からの前記依頼に応答する無線モニター情報に基づいて、同期対象候補基地局が前記基準基地局に対して同期ずれをしていないことを確認し、前記同期ずれをしていないことの確認の後に、同期対象候補基地局に対する無線同期を実行することを特徴とする。
