PROBLEM TO BE SOLVED: To allow a reconnection procedure to succeed even if a wireless base station to be connected to does not manage a "UE Context" related to a mobile station UE.SOLUTION: A mobile communication method includes: a step B in which a mobile station UE transmits a CGI of a cell #1 to a wireless base station eNB#2 in a reconnection procedure; and a step C in which the wireless base station eNB#2 acquires a "UE Context" related to the mobile station UE from a wireless base station eNB#1, which manages the cell #1 specified on the basis of the CGI, in the reconnection procedure, if the wireless base station eNB#2 does not manage the "UE Context" related to the mobile station UE.SELECTED DRAWING: Figure 4 【課題】接続先の無線基地局が、移動局ＵＥに係る「ＵＥ Ｃｏｎｔｅｘｔ」を管理していない場合であっても、再接続手順を成功させる。【解決手段】本発明に係る移動通信方法は、再接続手順において、移動局ＵＥが、無線基地局ｅＮＢ＃２に対して、セル＃１のＣＧＩを送信する工程Ｂと、かかる再接続手順において、無線基地局ｅＮＢ＃２が、移動局ＵＥに係る「ＵＥ Ｃｏｎｔｅｘｔ」を管理していない場合、かかるＣＧＩに基づいて特定されるセル＃１を管理する無線基地局ｅＮＢ＃１から、かかる移動局ＵＥに係る「ＵＥ Ｃｏｎｔｅｘｔ」を取得する工程Ｃとを有する。【選択図】図４
