RELAY DEVICE AND COMMUNICATION METHOD

PROBLEM TO BE SOLVED: To reliably prevent a terminal unit of a relay device including the terminal unit for performing radio communication with a radio base station and a base station unit for performing radio communication with a radio terminal from connecting to the base station unit of the relay device or the base station unit of another relay device.SOLUTION: A relay device includes a terminal unit for performing radio communication with a radio base station and a base station unit for performing radio communication with a radio terminal, and relays radio communication between the radio base station and the radio terminal. The base station unit transmits base station information allocated to the base station unit of the relay device in advance by using a system information block that transmits base station information in a notification signal. The terminal unit receives base station information in the system information block in the notification signal about a base station including the base station unit which the terminal unit can receive a signal from, checks the base station information with the pre-stored base station information allocated to the base station unit of the relay device, and excludes the base station having transmitted the base station information from a connection destination candidate if they accord.SELECTED DRAWING: Figure 2 【課題】 無線基地局と無線通信を行う端末部と無線端末と無線通信を行う基地局部を有する中継装置の端末部が、自分装置の基地局部または他の中継装置の基地局部へ接続することを確実に防止する。【解決手段】無線基地局と無線通信を行う端末部と無線端末と無線通信を行う基地局部を有し、無線基地局と無線端末の無線通信を中継する中継装置であって、基地局部は、報知信号の基地局情報を送信するシステム情報ブロックで、予め中継装置の基地局部に割り当てられた基地局情報を送信し、端末部は、端末部が信号を受信可能な前記基地局部を含む基地局について、報知信号のシステム情報ブロックの基地局情報を受信して、予め記憶しておいた中継装置の基地局部に割り当てられた基地局情報と照合し、一致した場合には、該基地局情報を送信してきた基地局を接続先候補から外す。【選択図】図２
