Communication system

Abstract

A communication system in which when judging to have received an RRC message from a communication terminal device, a base station device, for example, HeNB checks an MTCD indicator to be mapped to the received RRC message. Then, when judging that the UE that has transmitted the RRC message received 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.

1 - 4 . (canceled) 
     
     
         5 . A communication system comprising:
 a plurality of base station devices connected to a core network; and   a plurality of terminal device groups including communication terminal devices connected to each of said base station devices to perform radio communication,   wherein said plurality of base station devices include
 base station devices capable of performing a concentration process of concentrating data transmitted and received from a plurality of said communication terminal devices, and 
 base station devices incapable of performing said concentration process, and 
   wherein said base station devices capable of performing said concentration process notifies said core network of performing said concentration process.   
     
     
         6 . The communication system according to  claim 5 ,
 wherein each of said base station devices
 determines whether said base station device is capable of performing said concentration process when receiving a paging message containing information indicating performing said concentration process, and 
 transmits said paging message to each of said communication terminal devices upon determining that said base station device is capable of performing the concentration process.
