Communication system, radio network controller and base station

Abstract

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).

1 . (canceled) 
     
     
         2 . A communication system comprising:
 a base station configured to perform radio communication with a communication terminal device; and   a radio network controller configured to control the base station, wherein   the radio network controller transmits, to the base station, a paging message including a machine type communication (MTC) information indicating that the communication terminal device is an MTC device.   
     
     
         3 . The communication system according to  claim 2 , wherein
 the radio network controller transmits, to the base station, a paging message including an MTC identification information for identifying the MTC device.   
     
     
         4 . A radio network controller, which is configured to control a base station configured to perform radio communication with a communication terminal device, wherein
 the radio network controller transmits, to the base station, a paging message including a machine type communication (MTC) information indicating that the communication terminal device is an MTC device.   
     
     
         5 . A base station, which is configured to perform radio communication with a communication terminal device, wherein
 the base station receives a paging message including a machine type communication (MTC) information indicating that the communication terminal device is an MTC device, the paging message being transmitted from a radio network controller configured to control the base station.
