摘要:
A mobile communication system capable of performing communication between a user equipment device connected to a relay device and a core network if the relay device moves. A relay device sets a tracking area of a base station device to be connected with the own device as a tracking area of the own device. For example, when the relay device moves along an arrow, the tracking area of the relay device is changed from a first tracking area to which a fourth base station device belongs to a third tracking area to which a tenth base station device belongs. Upon change of the tracking area of the relay device as described above, a user equipment device transmits a tracking area update request signal of the own device to a target second mobility management entity.

In a mobile communication system, an RRM measurement set is set as a collection of cells to become targets on which a UE performs a process of detecting whether or not radio communication is allowed. Among the cells in the RRM measurement set, a CoMP measurement set is set as a collection of cells to become candidates on which the UE performs a process of detecting whether or not coordinated communication (CoMP communication) is allowed. Among the cells of the CoMP measurement set, a CoMP active set is set as a collection of cells to become targets on which the UE performs the process of detecting whether or not CoMP communication is allowed.
摘要:
A mobile communication system capable of continuing communication between a relay device and a base station device if the relay device moves. In a handover process, when it is judged that an establishment cause for RRC connection is attached from an RN, a target eNB judges whether the own device has the DeNB function. In a case of judging that the own device does not have the DeNB function, the target eNB notifies the RN of an RRC connection rejection. When being notified of the RRC connection reject, the RN stops the handover process and then returns to a source eNB.

A radio communication system capable of, in a case where a base station device is movable, easily estimating the location of a base station device and easily estimating the location of a user equipment device using the estimation results, and also provide a user equipment device, a base station device, and a management device included in the radio communication system. In addition to an E-SMLC for UE for use in location estimation of a target UE, an E-SMLC for eNB for use in location estimation of an eNB is provided. The E-SMLC for eNB estimates location information of an eNB in an E-UTRAN and performs a process, such as the management of moving of a target eNode B_s and a target eNode B_uu based on the estimated location information.

A mobile communication system capable of performing communication between a user equipment device connected to a relay device and a core network if the relay device moves. An RN sets a TA of an eNB to be connected with the own device as a TA of the own device. For example, when the RN moves along an arrow, the TA of the RN is changed from a first TA to which a fourth eNB belongs to a third TA to which a tenth eNB belongs. Upon change of the TA of the RN as described above, a user equipment device transmits a TA update request signal of the own device to a target second MME.
摘要:
A mobile communication system capable of reducing energy consumption of a network node in a local area range. When judging that there is a shift trigger, a local eNB shifts from a normal operation to an energy saving operation. In the energy saving operation, the local eNB stops the operation of transmitting at least a part of downlink transmission signals to be transmitted to a user equipment (UE) and performs the operation of receiving an uplink transmission signal transmitted from the UE. When judging that it has received the uplink transmission signal (RACH) in the energy saving operation, the local eNB shifts to the normal operation.
