Abstract

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 () according to the present disclosure includes a storage unit () 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 () configured to, in a case in which downlink data destined for a communication terminal managed by a mobility management device () is received after a failure has occurred in the mobility management device (), transmit a notification message with the temporarily allocated identification information and the eDRX parameter set therein to the mobility management device () or another mobility management device ().
