BASE STATION DEVICE, MOBILE TERMINAL, COMMUNICATION SYSTEM, AND RADIO COMMUNICATION METHOD

摘要

A base station device characterized by including: a transmission portion 32 that broadcast-transmits identification information indicating a first cell to a mobile terminal in an idle mode under control of the base station device; and a reception portion 34 that receives information indicating a destination cell that the mobile terminal in the idle mode transmits when moving between cells; wherein when the base station device is a base station device forming a second cell adjacent to the first cell, the reception unit receives information indicating the second cell from the mobile terminal in the idle mode which has received the identification information indicating the first cell transmitted from another base station device forming the first cell, and receives information indicating the first cell from the mobile terminal in the idle mode which has received the identification information indicating the first cell transmitted from the base station device.
