摘要： A cell2 configured by only a DL CC2 being a resource for downlink is configured. The cell2 does not include a resource for uplink, that is, a UL CC to be associated with the DL CC2 by a DL/UL link. The link information indicating the above is notified a communication terminal device by a base station device using the DL CC2. A DL CC1 and a UL CC constitute a cell1. The downlink communication from the base station device to the communication terminal device is performed using the cell1 and the cell2, and the uplink communication from the communication terminal device to the base station device is performed using the cell1.

摘要： A mobile communication system includes a CSG cell which is accessible by a CSG member, a hybrid cell which is the CSG cell where a non-CSG member is also allowed access at the same time, and a mobile terminal which is subscribed as the CSG member and connected to the CSG cell or the hybrid cell as the CSG member. Even in a case in which a subscription time period has expired, the mobile communication system enables the mobile terminal to continue the connection. When the subscription time period for the CSG member expires, in case of the mobile terminal's connection to the CSG cell, the CSG cell initiates a handover, in case of the mobile terminal's connection to the hybrid cell, the hybrid cell changes treatment for the mobile terminal from treating the mobile terminal as the CSG member to treating the mobile terminal as the non-CSG member.

摘要： A closed subscriber group (CSG) cell is a cell that allows use of subscribers. In order to receive the service by the CSG cell, a CSG-ID is required to be notified to a user equipment, which cannot be obtained in a situation outside the reach of radio waves from a non-CSG cell. In a mobile communication system including base stations respectively provided to a CSG cell and a non-CSG cell in which access is made to the CSG cell with the use of a CSG-ID issued in a case where use of the CSG cell is allowed, the base station provided in the CSG cell refers to the notified identification information of a user equipment and then transmits a tracking area update request from the user equipment to a core network, and the core network determines whether the user equipment is allowed to use the CSG cell and, in the case where the use is allowed, transmits a signal for allowing assignment of radio resources to the user equipment and the CSG-ID. The user equipment accesses the CSG cell with the use of the CSG-ID.

摘要： A mobile communication system hybridly allows, in a case where an access group consisting of one or more user equipments and one or more base stations is registered, the base station included in the access group to have access in a closed mode from the user equipment included in the same access group and access in an open mode from a user equipment that is not included in the same access group, wherein a communication area of the base station in the open mode is identical to a communication area of the base station in the closed mode. This eliminates a communication area in which the base station serving as an access destination differs between the user equipment in the closed mode and the user equipment in the open mode.

摘要： A mobile terminal 3 judges whether or not the mobile terminal is able to make a transition to a DTX period during Active, and, when judging that the mobile terminal is able to make a transition to a DTX period during Active, notifies a base station 2 to that effect. If the base station 2 judges that the mobile terminal is able to make a transition to a DRX period during Active when triggered by the notification from the mobile terminal 3, the base station temporarily stops supply of electric power to the data transmission processing units and the data reception processing units of the mobile terminal 3.

摘要： There is a problem that when a closed subscriber group (CSG) cell available to subscribers is installed in a macro cell area, communication cannot be performed due to the interference between a macro cell and the CSG cell in an area thereof. The CSG cell that is provided in the CSG cell area and transmits a downlink synchronization signal using a radio frame assigns control signals to a first subframe and a second subframe among a plurality of subframes constituting the radio frame, and the macro cell that is provided in the macro cell area and transmits a downlink synchronization signal using the radio frame assigns control signals to a third subframe and a fourth subframe, which are shifted from the first subframe and the second subframe by a predetermined number of subframes, respectively, among the plurality of subframes constituting the radio wave, the CSG cell and the macro cell being configured to perform transmission in synchronization with each other.
