We Claim:
1. A communication system comprising:
a terminal device; and
a base station configured to perform radio communication with the terminal device, wherein
machine type communication (MTC) control information that is control information for MTC is transmitted from the base station to the terminal device using a MTC control channel that is a control channel for MTC.
2. The communication system according to Claim 1, wherein
the MTC control information includes radio resource information that is information of a radio resource for transmitting data for MTC.
3. The communication system according to Claim 1, wherein
the terminal device is configured to receive the MTC control channel to obtain the MTC control information for the terminal device itself.
4. The communication system according to Claim 1, wherein
the terminal device is configured to receive data for MTC based on the MTC control information.
5. The communication system according to Claim 1, wherein
the MTC control channel is a common channel that can be commonly used by a plurality of terminal devices.
6. The communication system according to Claim 1, wherein
radio resource information that is information of a radio resource for transmitting the MTC control channel is transmitted from the base station to the terminal device.

7. The communication system according to Claim 6, wherein
the radio resource for transmitting the MTC control channel is periodically provided.
8. The communication system according to Claim 7, wherein
the radio resource information includes a cycle of the radio resource.
9. A terminal device, which is configured to perform radio communication with a
base station, wherein
the terminal device is configured to receive machine type communication (MTC) control information that is control information for MTC from the base station using a MTC control channel that is a control channel for MTC.
10. A base station, which is configured to perform radio communication with a
terminal device, wherein
the base station is configured to transmit machine type communication (MTC) control information that is control information for MTC to the terminal device using a MTC control channel that is a control channel for MTC.

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 the paging message is set individually for the normal UE and MTCD. Alternatively, the paging message contains a calling indicator in place of the equipment identity of the MTCD (UE-ID of MTCD).
