<p>In an attachment process as a relay node (RN), wasteful use of resources can be avoided. A mobile communication method of the present invention comprises: a step in which a radio base station (DeNB) transmits, to a mobile management node (MME), an "(S1) Initial UE message", which indicates an attachment process as a relay node (RN), in response to an "Attach Request (RN)" received from the relay node (RN) with which a USIM-RN has established a secure channel; a step in which the mobile management node (MME) starts an "EPS-AKA" between the mobile management node (MME) and each of the relay node (RN) and USIM-RN in response to the "(S1) Initial UE message"; and a step in which if it is determined that the USIM-RN cannot be used for the attachment process as the relay node (RN), the "EPS-AKA" fails.</p> |
