Abstract: A method performed by Access and Mobility Management Function, AMF (800) for handling of network slice specific authentication and authorization procedure, is disclosed. In an embodiment, a network shall restart a generic UE configuration update procedure when the network encounters radio link failure before completion of the ongoing generic UE configuration update procedure. In another embodiment, the network sends CONFIGURATION UPDATE COMMAND message containing the Allowed NSSAI when a N1 NAS signaling connection is established after the radio link failure.

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: User equipment, UE, includes: a receiver configured to receive a parameter indicating whether the UE is restricted or authorized for transmission of user data in a message transmitted on Uplink Synchronization Channel, UL-SCH, from an access network node; and a hardware processor configured to process instructions to determine whether the transmission of the user data in the message is restricted or authorized based on the parameter.

Abstract: An exposure node (50) receives a first request for resource management for future background data transfer between an application service provider and a plurality of radio terminals (10) from a server (60) associated with the application service provider and send a second request to a policy control node (40) in response to receiving the first request. The first request includes a parameter indicating whether background data transfer not complying with a previously agreed or negotiated transfer policy should be stopped, or whether the background data transfer should continue under a charging rule different from a previously agreed charging rule. The second request includes the parameter obtained from the first request. This enables the application service provider to negotiate with the radio communication network about handling of background data transfer not complying with a previously agreed transfer policy.

Abstract: This disclosure is related to a procedure to provide emergency services support for a UE which does not have a valid subscription for the serving PLMN. This disclosure more specifically provides procedure to support IMS emergency call or eCall support for a UE which is in limited state on a E-UTRA cell is connected to both EPC and 5GCN.

Abstract: This disclosure defines a procedure to handle authentication procedure during Xn handover. More specifically it defines handling of an authentication procedure when Xn handover takes place from one serving PLMN to another serving PLMN during the authentication procedure.

Abstract: A UE (1) receives, from a network (9, B), control information indicating an association of each of at least one Closed Access Group (CAG) ID with at least one network slice identifier. The UE (1) performs cell selection or cell reselection using the received control information. This allows the UE to take into account the availability of a network slice in cell selection and cell reselection in the case of a Public network integrated Non-Public Network (PNI-NPN), for example.

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: A core network node (3) stores a first association between a plurality of Home PLMN S-NSSAIs and a Serving PLMN S-NSSAI. The first association includes a second association between the Serving PLMN S-NSSAI and a Home PLMN S-NSSAI that is not subject to NSSAA, and a third association between the Serving PLMN S-NSSAI and another Home PLMN S-NSSAI subject to NSSAA. If a UE (1) does not support NSSAA feature and if a part of multiple Home PLMN S-NSSAIs presented by the UE (1) is included in the second association and the rest is included in the third association, the core network node sends information containing the second association to the UE (1). This can allow, for example, proper notification of information about a Mapped S-NSSAI available to a UE that does not support NSSAA.
