Abstract: Described are apparatuses, methods, and computer program products for enabling splitting, switching, and steering of access traffic in a system, e.g., a fifth-generation (5G) system. Access and mobility management functions (AMF) of the 5G system forward one or more of the registration requests to unified data management (UDM) functions of the PLMNs. UDM function determines whether evolved packet system (EPS) interworking (IWK) is allowed for respective registration requests based on subscription, deployment, system capabilities, a radio access technology (RAT) of an access path between the UE and the 5G system, etc. UE can include an indication that EPS IWK is requested and/or required in a registration request.

Abstract: There are provided measures for (enabling/realizing) network operability on a resource instance level in (a core network of) a mobile/wireless communication system. Such measures may exemplarily comprise that an initiator entity sends a service request for a service operation on a specific resource managed by a responder entity of the network, said service request comprising at least one resource filter specifying a set of resource instances of the specific resource that the service operation is to be performed on, and receives a service response to the service request from the responder entity, said service response comprising a result of performing the service operation on the set of resource instances specified by the at least one resource filter.

Abstract: Methods and apparatuses for improving service continuity are disclosed. The solution comprises storing (300) information slice remapping describing how a given net-work slice may be mapped to another network slice, receiving (302) a first message from an access node, that the node serves a terminal or has received a request to serve a terminal utilising a network slice not supported by the node and transmitting (304) based on the first message a message to a network entity responsible for session management to control the connection of the terminal, with the information on slice remapping and/or activity status of the packet data unit sessions associated with the slice not supported by the node.

Abstract: There is provided an apparatus, method and computer program for an apparatus for a first policy control function, that causes to apparatus to: receive, from a session management function, a request for a policy to be established for a session for a subscriber, wherein the subscriber is subscribed in a second domain and the first policy control function is configured to operate in a first domain; determine a policy for the requested session, the determined policy comprising an indication of an allowed usage for the subscriber and at least one trigger condition for the policy to be updated; signal the at least one trigger condition to the session management function; and monitor the allowed usage for the subscriber by updating the policy in response to receipt of an indication that the at least one trigger condition has been met.

Abstract: There is provided an apparatus comprising means for receiving information about an identification of a network function set associated with at least one packet data network connection. The means is further configured for, in response to receiving an indication that a network function instance of the network function set supporting the at least one packet data network connection is no longer available, transferring the at least one packet data network connection from the network function instance to another network function instance comprised within the network function set.

Abstract: This document discloses a solution for selecting a network slice for an application. According to an aspect, a method comprises as performed by a terminal device: triggering, by the terminal device, network slice selection in the terminal device for an application executed in the terminal device; transmitting, by the terminal device in response to said triggering, a network slice query request message to a network node of a network infrastructure; receiving, by the terminal device from the network node as a response to the network slice query request message, a network slice query response message indicating at least one network slice available to the terminal device and comprising at least one quality-of-service parameter of the at least one network slice; and selecting, by the terminal device, a network slice of the at least one network slice for the application on the basis of the at least one quality-of-service parameter.

Abstract: The apparatus includes a processor configured to send, over a 3rd Generation Partnership project (3GPP) access, a notifying message regarding non-3GPP access to a user equipment, the user equipment being simultaneously registered to the communication network via the 3GPP access and via the non-3GPP access, the user equipment being in a connection management-idle state over the non-3GPP access. The method includes sending over a 3rd Generation Partnership project (3GPP) access a notifying message regarding non-3GPP access to a user equipment, the user equipment being simultaneously registered to a communication network via the 3GPP access and via the non-3GPP access, the user equipment being in a connection management-idle state over the non-3GPP access.

Abstract: A method, apparatus and computer program product are provided in accordance with example embodiments in order to provide methods, apparatuses, and/or systems that reduce and/or eliminate network inefficiencies caused by the persistence of user-equipment-specific associations with network interfaces and elements, including but not limited to user-equipment-specific associations on at least N2. In some example implementations, an AMF may assign a temporary ID containing particularized identification information to a UE in a manner that allows for selection by a (R)AN of a AMF and that enables an AMF to process an N1/N2 transaction, such as may occur when a UE enters an idle mode and/or transitions from an idle mode to a connected mode.
