Abstract

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.

Claims

1. A communication system, which comprises a base station device connected to a core network and a plurality of terminal device groups including communication terminal devices connected to said base station device so as to perform radio communication,

wherein upon reception of data transmitted from a plurality of said communication terminal devices to said core network, said base station device performs a concentration process of concentrating the received data on said terminal device groups and transmits the data obtained through said concentration process to said core network.

2. The communication system according to claim 1, wherein said base station device transmits the data obtained through said concentration process to said core network in an allowed period predetermined as a period in which transmission is allowed.

3. The communication system according to claim 1, wherein said base station device transmits the data obtained through said concentration process to said core network over allowed resources predetermined as radio resources in which transmission is allowed.

4. The communication system according to claim 1, wherein upon reception of a predetermined message or signal from said communication terminal device, said base station device transmits the data obtained through said concentration process to said core network.
