Abstract: There is provided an apparatus for use in a user equipment, wherein the user equipment is operable to be registered in a registration area, the apparatus comprising means configured to perform: providing, to a first network entity, a first message, wherein the first message comprises an indication that the user equipment supports non-uniformly supported network slices in the registration area. The means further configured to perform receiving, from a second network entity, a second message, wherein the second message comprises group mapping information for a tracking area of the registration area, wherein the group mapping information maps the tracking area to at least one group, the at least one group comprising a list of network slices that are non-uniformly supported in the tracking area.

Abstract: Methods and apparatus, including computer program products, are provided for congestion management and service continuity. In some example embodiment, there may be provided a method comprising sending, by a user equipment, an indication of whether the user equipment supports an automatic re-mapping of a network slice to a fallback network slice; and receiving, by the user equipment, an acknowledgment from a network in response to the sent indication. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: Methods, apparatuses, and computer program products are described that support access to multiple mutually exclusive, isolated, and/or disjointed network slices by User Equipment, UE, across one or more networks. The UE connects (1102) to multiple network slices via a Radio Access Network, RAN, by way of one or more Radio Resource Control, RRC, connections. The RRC connections are maintained (1104) between the UE and a respective network slice by switching the connection to inactive or idle when another RRC connection needs to be established. The UE and/or the RAN switches (1106) an RRC connection from an inactive state to an active state based on a trigger condition such as receipt of a notification that downlink data is available over the inactive RRC connection. A Unified Data Management Function, UDM, stores and updates registration state information for the UE and multiple Access and Mobility Management Functions, AMFs.

Abstract: There is provided an apparatus in a first network access node, the apparatus comprising means configured to perform: obtaining cell information comprising a list of network slices supported by at least one neighbour cell neighbouring a serving cell, wherein the network slices in the list are non-uniformly supported in a tracking area associated with the at least one neighbour cell. The means further configured to perform: identifying, using the obtained cell information, a target cell from the at least one neighbour cell that supports a network slice currently used by a user equipment, for performing a change from the serving cell to the target cell.

Abstract: A method comprises receiving network slice information from a core network entity, the network slice information related to a network slice which is not supported in one or more cells of a first tracking area, but which is supported in one or more cells of a second tracking area. The method further comprises triggering a procedure at a user equipment to access said network slice based on said network slice information when said user equipment is in one or more cells of the first tracking area.
