Abstract
In an attach process executed as a relay node RN, the wasteful use of a resource is avoided. A mobile communication method according to the present invention includes a step of transmitting, by a radio base station DeNB, '(S1) Initial UE message' indicating the attach process executed as the relay node RN to a mobile management node MME in response to 'Attach Request (RN)' received from the relay node RN having a secure channel established between the relay node RN and USIM-RN, a step of starting, by the mobile management node MME, “EPS-AKA” between the relay node RN and the USIM-RN in response to the “(S1) Initial UE message”, and a step of failing in the “EPS-AKA” when it is determined that the USIM-RN cannot be used for the attach process executed as the relay node RN.
