摘要

The present disclosure is directed to providing a gateway device that can properly page a communication terminal managed by a control device even if the control device loses information on the communication terminal when the control device recovers from a failure that has occurred therein. A gateway device (10) according to the present disclosure includes a storage unit (11) configured to store temporarily allocated identification information temporarily allocated to a communication terminal and an eDRX parameter associated with the communication terminal, and a transceiver (12) configured to, in a case in which downlink data destined for a communication terminal managed by a mobility management device (20) is received after a failure has occurred in the mobility management device (20), transmit a notification message with the temporarily allocated identification information and the eDRX parameter set therein to the mobility management device (20) or another mobility management device (21).
