Abstract
In a communication system, an eNB and a UE transmit and receive a UE monitoring message for confirming the state of the UE in a predetermined UE monitoring period. For example, in UE monitoring periods, a UE monitoring procedure is performed, so that the UE transmits the UE monitoring message to the eNB. Upon receipt of the UE monitoring message, the eNB transmits delivery confirmation information to the UE. The UE monitoring period is set as, for example, a period shorter than a TAU period. This allows the UE monitoring process to confirm the state of the UE even if the TAU period is lengthened. The eNB may transmit the UE monitoring message to the UE.
