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 (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).

Abstract: An object of the present disclosure is to provide an access network node, a user equipment, a network function node and a control method capable of steering a UE in connected mode. In one example aspect, a control method for an access network node includes: receiving, from a network function node for mobility management, at least one first network slice information, each of which is different from a second network slice information being used for a Protocol Data Unit, PDU, session with a user equipment, UE; and performing a redirection procedure for the UE from a first cell to a second cell which supports one of the at least one first network slice information in a case where the second network slice information is not available in the first cell.

Abstract: This disclosure handles a registration procedure in a UE supporting registration to 5GC via untrusted non-3GPP access network and 3GPP access network. More specifically this disclosure defines a UE behavior when a registration procedure is not successful to 5GC via first access network type (e.g. untrusted non-3GPP network access) after transmitting maximum number of registration request message via the first access network type to the 5GC and the UE is registered to 5GC via other access network type (e.g. 3GPP access network (NG-RAN)).
