COMMUNICATION SYSTEM

摘要

This invention provides a communication system that can prevent the switching between the normal operating state and power saving state of a power saving cell from being unnecessarily performed. The power saving cell (ES cell) is in a dormant state that is the power saving state (in a step ST1101). When the ES cell receives a wakeup request message from a communication terminal apparatus (UE) (in a step ST1104), the ES cell executes an access limit control and determines whether the UE can access the ES cell (in a step ST1106). If the ES cell determines that the UE can access the ES cell, the ES cell switches itself on (in a step ST1109) and transitions from the dormant state to an active state that is the normal operating state (in a step ST1110).
