Abstract: A communication control method pertaining to an embodiment of the present invention is for controlling dual connectivity communication which uses a master base station that establishes RRC connection with a user terminal and a secondary base station that provides a supplementary wireless resource to the user terminal. The communication control method comprises: a step in which the master base station receives, from the user terminal, a measurement report which includes measurement results found for each cell in the user terminal; and a step in which the secondary base station receives, from the master base station, a supplementary request for requesting the allocation of resources to the user terminal. In the step for receiving a supplementary request, the master base station includes, in the supplementary request, measurement results for a cell of the secondary base station which is included in the measurement results, and transmits the same.

Abstract: A user terminal capable of using an Evolved-UMTS Terrestrial Radio Access Network (E-UTRAN) and a Wireless Local Area Network (WLAN), includes: a storage configured to store a Radio Access Network (RAN) rule for selecting a network, among the E-UTRAN and the WLAN, to be used in a unit of an Access Point Name (APN); a receiver configured to receive an Access Network Discovery and Selection Function (ANDSF) rule for selecting a network, among the E-UTRAN and the WLAN, to be used; and a controller configured to select a selection rule, from among the ANDSF rule and the RAN rule, to be applied to change the network, wherein the controller selects the RAN rule in a case where the user terminal has both the ANDSF rule and the RAN rule and an Inter System Routing Policy (ISRP) is not configured. The ISRP is a function, in the ANDSF rule, for selecting a network, among the E-UTRAN and the WLAN, to be used in a unit of an Internet Protocol (IP) flow.

Abstract: UE 100 transmits and receives traffic to and from eNB 200 in a cellular communication system capable of cooperating with a WLAN system. The UE 100 determines, on the basis of a determination parameter related to a situation of the UE 1001, whether or not an offload in which the traffic is transitioned to the WLAN system should be performed, when the UE 100 is selected as a target terminal subject to the offload. The UE 100 transmits, to the eNB 200, a rejection notification that related to rejection to the offload when the UE 100 determines that the offload should not be performed.

Abstract: An MBS (master base station), UE (user equipment) and method operate using dual connectivity where the UE is connected to an MBS and a SBS (secondary base station). Capability information is transmitted to the MBS by the UE and indicates whether the UE supports a SCG (Secondary Cell Group) bearer and whether the UE supports a split bearer split in a PDCP (Packet Data Convergence Protocol) layer of the MBS. The UE receives from the MBS a message configuring, but not simultaneously configuring, either the SCG bearer or the split bearer to the UE. Radio protocols of the SCG bearer are only located in the SBS, and radio protocols of the split bearer are located in both the MBS and the SBS. One split path of the split bearer goes via the SBS and another split path of the split bearer goes via the MBS and not via the SBS.

Abstract: A communication control method and secondary base station perform a dual connectivity scheme in which a master base station and a secondary base station are used, the master base station establishing an RRC connection with a user terminal, and the secondary base station providing additional radio resources to the user terminal. The method includes the secondary base station receiving predetermined information from the master base station, the secondary base station determining, based on the predetermined information, whether or not the random access procedure is required between the user terminal and the secondary base station, and the secondary base station transmitting to the user terminal, based on a result of the determination, a message for triggering the user terminal to initiate the random access procedure.

Abstract: A communication control system, user terminal, and processor for controlling a user terminal in which a user terminal controls communication by using a first data bearer and a second data bearer, where the first data bearer does not pass through a Wireless Local Area Network (WLAN), but passes through the cellular base station, and the second data bearer passes through the WLAN and the cellular base station. The cellular base station controls communication with the user terminal by using the first data bearer and the second data bearer. The user terminal receives information transmitted from the cellular base station, where the information is for the user terminal to transmit a status report indicating a delivery status regarding data received via the WLAN and data directly received from the cellular base station. The user terminal transmits the status report to the cellular base station on a basis of the information.
