FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radio communication. A mobile communication method according to the present invention includes steps of: transmitting an "Extended Service Request" from a mobile station UE in idle mode to a mobility management node MME via a radio base station eNodeB; transmitting an "Initial UE Context Setup Request" from the mobile station UE to the radio base station eNodeB, the "Initial UE Context Setup Request" containing priority call information; and preferentially allocating resources to the E-RAB for the mobile station UE by the radio base station eNodeB based on the priority call information contained in the received "Initial UE Context Setup Request".
EFFECT: enabling preferential setup of E-RAB (Evolved Radio Access Bearer) and RAB (Radio Access Bearer, for use as packet bearers, and also enabling priority checking for a RRC (Radio Resource Control) signal in CSFB (CS Fallback) procedures).
