RADIO BASE STATION AND COMMUNICATION DEVICE

PROBLEM TO BE SOLVED: To reduce a possibility that a full configuration is executed in handover.SOLUTION: A radio base station eNB1 is capable of radio communication with a terminal device UE. The radio base station eNB1 includes: a determination unit 12 for determining whether a radio base station eNB2 has functions different from those of the radio base station eNB1 when the terminal device UE is handed over from the radio base station eNB2 to the radio base station eNB1; and an instruction unit 13 for instructing the terminal device UE to delete setting information on radio communication with the radio base station eNB2 if a result of the determination by the determination unit 12 is affirmative.SELECTED DRAWING: Figure 10 【課題】ハンドオーバにおいてFull Configurationが実施される可能性を低減させる。【解決手段】端末装置ＵＥと無線通信可能な無線基地局ｅＮＢ１であって、端末装置ＵＥを無線基地局ｅＮＢ２から無線基地局ｅＮＢ１へハンドオーバさせる際に、無線基地局ｅＮＢ２が無線基地局ｅＮＢ１の有する機能とは異なる機能を有するか否かを判定する判定部１２と、判定部１２による判定の結果が肯定の場合、端末装置ＵＥに対して、無線基地局ｅＮＢ２との無線通信に関する設定情報の削除を指示する指示部１３と、を備える、ことを特徴とする無線基地局ｅＮＢ１。【選択図】図１０
