Abstract: Methods and apparatus, including computer program products, are provided for UE capability signaling. An apparatus is provided that is caused to at least: receive, from a user equipment capability management function, a message including a first restart counter value indicating a restart of the user equipment capability management function; inhibit, in response to receiving the first restart counter value, one or more old user equipment capability identifiers associated with a second restart counter value, the second restart counter value being associated to a pre-restart state of the user equipment capability management function; and send the first restart counter value indicating the restart of the user equipment capability management function. Related systems, methods, and articles of manufacture are also described.

Abstract: Systems, methods, apparatuses, and computer program products for efficient registration for partially supported service areas are provided. One method may include providing, to at least one user equipment registered to a network within a registration area, information comprising one or more lists of single network slice selection assistance information (S-NSSAIs) and one or more lists of tracking area identities (TAIs). The one or more single network slice selection assistance information (S-NSSAIs) is included in a list of rejected single network slice selection assistance information (S-NSSAIs) or in a list of extended rejected single network slice selection assistance information (S-NSSAIs), and is associated with a cause value indicating that the one or more single network slice selection assistance information (S-NSSAIs) is not supported uniformly in the registration area and is not supported in a current tracking area.

Abstract: Techniques for controlling the behavior of a user device toward a cell in a sliced network are provided. For example, a method of controlling a user device is disclosed. The method comprises: receiving, by the user device, a configuration message from a network node, the configuration message indicating whether to perform a cell reselection procedure and/or a random-access procedure taking into account priority of one or more network slice groups; and performing, by the user device, the cell reselection procedure and/or the random-access procedure taking into account priority of one or more network slice groups in accordance with the configuration message.

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.
