MOBILE COMMUNICATION SYSTEM, RADIO BASE STATION, MOBILITY MANAGEMENT NODE AND USER EQUIPMENT

摘要

To avoid the situation in which user equipment (UE) that is not a CSG member uses a CSG cell as an Scell in CSG control, this radio base station (eNB) is provided with: a management unit (12) configured to manage a Pcell list and/or an Scell list; a reception unit (11) configured to acquire Pcell member information and/or Scell member information from user equipment (UE) in a cell (#10); and a control unit (13) configured to refer to the management unit (12) on the basis of the Pcell member information and/or the Scell member information, determine whether or not the user equipment (UE) can be connected as a Pcell to the cell (#10), and determine whether or not the user equipment (UE) can set the cell (#10) as an Scell.
