    摘要： The present invention has an object to provide a communication system capable of mitigating, even if a large number of terminal device groups to be served by a base station device are located, congestion of a core network in a situation in which data is required to be communicated from the large number of communication terminal devices or to the large number of communication terminal devices at the same time. In the present invention, when judging to have received an RRC message from a communication terminal device (UE) in Step ST1601, a base station device, for example, HeNB checks an MTCD indicator to be mapped to the received RRC message in Step ST1602. Then, when judging that the UE that has transmitted the RRC message received in Step ST1601 is an MTCD being a device for machine type communication (MTC) from the checked MTCD indicator, the HeNB performs a concentration process on the data from the MTCD to the core network in Step ST1604.

    摘要： The present invention has an object to provide a communication system capable of avoiding congestion in downlink communication or uplink communication and a shortage of radio resources arising therefrom. In the present invention, in a communication system including a normal user equipment (normal UE) that performs human to human communication and a machine type communication device (MTCD) that performs machine to machine communication, a base station device transmits a paging message to the normal UE and the MTCD for calling the normal UE and the MTCD. The paging message contains, for example, an equipment identity (UE-ID). A maximum number of equipment identities (UE-IDs) that can be accommodated within this paging message is set individually for the normal UE and the MTCD. Alternatively, the paging message contains a calling indicator in place of the equipment identity of the MTCD (UE-ID of MTCD).

    摘要： A communications method and a mobile terminal that constructs a communications system which transmits data by using an OFDM (Orthogonal Frequency Division Multiplexing) method as a downlink access method, and also transmits data by using an SC-FDMA (Single Career Frequency Division Multiple Access) method as an uplink access method. The mobile terminal includes a processor that determines a candidate set including CCEs (Control Channel Elements), each of which is one of regions to which one frequency bandwidth is divided, for delivery of an L1/L2 control signal which is control information transmitted and received between a base station and the mobile terminal. In addition, the processor, which is at the mobile terminal, determines the candidate set based on the frequency bandwidth.

    摘要： Since OFDM (Orthogonal Frequency Division Multiplexing), which is a downlink access scheme used for an LTE (Long Term Evolution) communication system, is weak at interference, it is preferable that the number of base stations for transmitting the same E-MBMS (Evolved Multimedia Broadcast Multicast Service) data be not excessive.Thus, the mobile terminal performs: processing of obtaining measurement quality values by measuring reception quality of each base station; processing of deciding on whether the measurement quality value of a serving base station exceeds a certain receiving level; processing of adding measurement quality values of other base stations to the measurement quality value of the serving base station until the sum exceeds the certain receiving level; and processing of notifying the serving base station of the serving base station and other base stations as candidates for an active set for E-MBMS. This makes it possible to select as the active set for E-MBMS an appropriate number of base stations that make it compatible to maintain good reception quality and to prevent interference.
