Abstract: A base station according to the present embodiment receives, if the radio terminal is in a connected mode, via a bearer between the base station and a serving gateway, downlink data addressed to the radio terminal, from the serving gateway, and includes a controller configured to transmit the downlink data to the radio terminal. The controller does not release but maintains the bearer, if the extended DRX operation is configured to the radio terminal, when the radio terminal transitions to the idle mode. The controller receives, even if the radio terminal is in the idle mode, from the serving gateway, the downlink data addressed to the radio terminal, via the bearer, and buffers the downlink data until the downlink data is transmitted to the radio terminal.

Abstract: A communication control method is a method for performing an offload from a cellular RAN to a wireless LAN. The communication control method includes the steps of: transmitting a list which contains identifiers of wireless LAN access points included in the wireless LAN, by a cellular base station included in the cellular RAN; receiving the list, by a user terminal which has a cellular communication unit and a wireless LAN communication unit; and performing an operation related to the offload after detecting that the user terminal approaches a wireless LAN access point on the basis of the list, by the user terminal which exists in a cell of the cellular base station.

Abstract: A communication control method is a method for performing offload to transfer a traffic load of a cellular base station to an access point. The communication control method comprises a step of maintaining without releasing the first connection, by a user terminal that have established a first connection with the cellular base station, even when the offload is started after establishing a second connection with the access point; and a determining step of determining, by the user terminal, whether the offload is continued or canceled after the offload is started.

Abstract: A communication control method according to one embodiment is used in a mobile communication system. The communication control method comprises a step A of predicting, by a UE, a radio condition within a second period after connection between the UE and a eNB is established, in a first period for which the connection is not established, and a step B of performing, by the UE, a random access procedure for establishing the connection. The step B includes a step of performing notification of information on the predicted radio condition from the UE to the eNB in the random access procedure. The information is used, by the eNB, for controlling communication with the UE.
