Abstract: Described is an approach for managing network capabilities for a user equipment (UE). A UE can maintain subscriber data that comprises an entry index of networks for which various access modes are enabled/disabled, and a counter for each network/access mode combination. After requesting access to a network, the UE may receive a non-integrity protected rejection message that indicates the network does not allow a particular access mode. Based on the cause of access rejection, the UE can disallow the particular access mode for the network, start a timer, and increment a counter associated with the network/access mode combination. Once the timer expires, if the counter value is below a threshold the UE re-enables the particular access mode for the network, or if the counter value is at or above the threshold, the UE removes the respective entry index for the particular access mode for the network.

Abstract: A method, apparatus and computer program product may be provided for providing always-on as an attribute of a PDU session, providing interworking aspects with respect to an always-on PDU session, and enabling network determination of whether a PDU session will be an always-on PDU session. An example method may include receiving, from UE, a PDU session establishment request message, the PDU session establishment request message comprising an always-on PDU session requested IE set to a value indicative of a request to establish a new-always on PDU session (e.g., “Always-on PDU session requested”), and upon a determination that the requested PDU session shall be established as an always-on PDU session, cause transmission of a PDU session establishment accept message, the PDU session establishment accept message comprising an always-on PDU session indication IE that is set to a value indicative of always-on PDU session required (“Always-on PDU session required”).

Abstract: A technique includes detecting, by a user device, a network slice associated with an access attempt by the user device to access a wireless network, and making, by the user device, a barring decision for the access attempt based on the network slice associated with the access attempt. Another example technique may include receiving, by a base station from one or more core network entities within a wireless network, network slice-specific load information that indicates a load for each of one or more network slices, determining, by the base station based on the received network slice-specific load information, a barring configuration that indicates a set of barring parameters for one or more access categories, and sending, by the base station to a user device, the barring configuration to reduce a load on the wireless network.
