Abstract: A communication system is provided that can improve the communication capability of a communication terminal device in the case where a large number of small cells in addition to a macro cell are installed and operated. A communication terminal device (UE) is connected with a macro cell configured by a MeNB and a small cell configured by a SeNB, so that dual connectivity is performed. When receiving information for small cells, for example, emergency information from a CBC via an MME, at least one cell of the macro cell and the small cell notifies the communication terminal device connected with the at least one cell of the information for small cells.
