GATEWAY DEVICE, MOBILITY MANAGEMENT DEVICE, BASE STATION, COMMUNICATION METHOD, CONTROL METHOD, PAGING METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2018074522
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gateway device that can normally conduct paging to a communication terminal managed by a control device even if the control device has lost information on the communication terminal when a failure occurs to the control device and then is repaired.SOLUTION: A gateway device 10 according to the present disclosure includes: a storage unit 11 for storing temporary allocation identification information temporarily allocated to a communication terminal and an eDRX parameter related to the communication terminal; and a communication unit 12 for transmitting a notification message in which the temporary allocation identification information and the eDRX parameter are set to a mobility management device 20 or another mobility management device 21 when receiving downlink data to the communication terminal managed by the mobility management device 20 after a failure has occurred to the mobility management device 20.SELECTED DRAWING: Figure 1
