Abstract: In a dual connectivity, the X2-GW collects operation information from a plurality of HeNBs. The X2-GW obtains a measurement result of radio quality reported by the UE to the MeNB from the MeNB. Based on the operation information of the HeNB and the measurement result, the X2-GW identifies transmission destination of a SeNB addition request message received from the MeNB, and sends the SeNB addition request message to the identified HeNB. Upon acquiring an acknowledgment message for the SeNB addition request message from the HeNB, the X2-GW sends the message to the MeNB.

Abstract: A communication method according to an embodiment comprises: a step of performing, by a user terminal, a reselection of a target cell to be used as a serving cell from among a plurality of cells operated at different frequencies. The step of performing the reselection of the target cell comprises: a first reselection step of performing, by the user terminal, the reselection of the target cell in a response to reception of a paging signal for requesting the reselection of the target cell from a current serving cell; and a second reselection step of performing, by the user terminal, the reselection of the target cell in a response to a trigger without dependence on the paging signal. In the first reselection step, the user terminal starts measurement of a quality of a measurement target frequency included in system information broadcast from the current serving cell, in response to the reception of the paging signal.
