Abstract: Methods, systems, apparatuses, and computer program products provide network function selection for user equipment via a gateway network node. In an implementation, a single-network slice selection assistance information (S-NSSAI) list is received from a user equipment (UE). Additionally, it is determined whether a network node does not support a non-access stratum node selection function for the UE. Based on a determination that the network node does not support the non-access stratum node selection function for the UE, an initial UE message configured with an information element for the S-NSSAI list is generated, and the initial UE message is caused to be transmitted to a gateway network node to select a core network function for the UE.

Abstract: Methods and apparatus, including computer program products, are provided for public warning messages. In some example embodiment, there may be provided a method including receiving, at a user equipment, an indication, wherein the indication indicates whether a radio access network provides support for public warning system warning messages and/or indicates whether the radio access network allows the public warning system warning messages to be received by non-allowed user equipment; and deciding, by the user equipment, whether to select or reselect the radio access network based on the received indication. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: Methods and apparatus, including computer program products, are provided for handling non-integrity protected reject messages in non-public networks. In some example embodiments, there may be provided an apparatus including at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least: receive, from a network function in a standalone non-public network (SNPN), a reject message, wherein information in the reject message indicates that the apparatus is not allowed to access the SNPN by subscription; and add the identity of the SNPN in a list of forbidden SNPNs associated with an access via which the apparatus sent a request and subsequently received the reject message.

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: In some example embodiments, there may be provided a method that includes receiving, at a user equipment while being served by a first system and during protocol data unit session establishment or modification procedure, a message including an access point name aggregate maximum bit rate value; and when there is an inter-system change from the first system to the second system, setting, at the user equipment, the access point name aggregate maximum bit rate value of a session management context for the second system to the received access point name aggregate maximum bit rate value received while being served by the first system. Related systems, methods, and articles of manufacture are also described.

Abstract: Methods, apparatuses, and computer program products are provided for handling session requests for emergency services. Updated closed access group (CAG) configuration information can be provided to user equipment (UE) requesting an emergency session with a public land mobile network (PLMN), and the UE may update their CAG information or discontinue its session request. When the PLMN determines that the UE's session request to the PLMN was sent via a non-CAG cell, the PLMN may then determine if the session request is for emergency services, in which case the PLMN may decide to not clear or reject the session request, while if the PLMN determines that the session request via the non-CAG cell is for non-emergency services, then the PLMN may clear or reject the session request. When a session request is rejected by the PLMN, the UE may enter a deregistered state and conduct a search for a new PLMN.
