Abstract: Techniques for providing distributed NAS layer termination points within a communication network. A network entity assigns a non-access stratum temporary identifier to a user device. The non-access stratum temporary identifier is associated with a non-access stratum termination point, and wherein a type of non-access stratum termination point is based at least in part on an apparatus type configured to handle one or more non-access stratum messages. The network entity causes the user device to be provided with the non-access stratum temporary identifiers.

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 single network slice selection assistance information (S-NSSAIs) and one or more tracking area identities (TAIs). Each of 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 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: Methods, apparatuses, and computer program products are described that support non-uniform network slice deployment across a service area of a registration area or tracking area covered by at least a radio access network. A network function transmits a plurality of tracking area codes associated with a network to user equipment to indicate primary and secondary tracking area codes to the user equipment. Selection of a tracking area code may be completed by the user equipment based on the primary and secondary tracking area codes and a forbidden tracking area identities list. The user equipment may be blocked from receiving services from a network slice based on the service area in which the user equipment attempts to access the network slice. Network functions may limit reporting of tracking area codes to user equipment based on a serving cell identity. Network slices may be restricted to private networks.

Abstract: A method may include receiving, by a traffic ingress entity of a communication network, one or more packets of a traffic flow. The method may also include assigning a classification, by the data reception entity, to each packet of the one or more packets of the traffic flow according to one or more protocol data unit sets to which the packet belongs to. The method may further include mapping the one or more packets of the traffic flow to one or more quality of service flows for quality of service handling of the one or more packets based on the classification assigned to each packet. In addition, the method may include outputting the classification assigned to each packet to a network element for enabling quality of service handling of the one or more packets based on the mapping and one or more quality of service information.

Abstract: A method, apparatus, and computer program product are disclosed for modifying the transmission of media content update packets based on a determination that the elapsed uplink time and remaining downlink time in the aggregate are within a satisfactory round-trip delay time. In this regard, the method, apparatus, and computer program product are configured to correlate a returned media content update packet with an associated device update packet or packets. Correlating media content update packets with an associated device update packet may require identifying a returned packet containing a media content update by analyzing packets containing video streams to identify packets comprising reference video frames. Identifying reference video frame packets may assist in identifying the associated uplink packet or packets containing device pose and position or other user input.

Abstract: Systems, methods, apparatuses, and computer program products for working clock determination for a mobile user equipment. A method may include receiving time domain information at a session management function during a protocol data unit (PDU) session procedure. The method may also include forwarding the time domain information to a user plane function for the PDU session procedure. The method may further include configuring the user plane function according to the time domain information to enable determination of a correct mapping between the time domain information and a user equipment or a PDU session.

Abstract: A method, apparatus and computer program product are provided for efficiently activating or deactivating user equipment. An example method includes receiving a deactivation request comprising one or more identifiers for one or more user equipment or one or more user equipment groups, determining which one or more user equipment or user equipment groups are impacted by the deactivation request and causing a suspend request to be transmitted to the one or more user equipment or user equipment groups that are impacted. Another example method is provided for receiving an activation request comprising one or more identifiers for one or more user equipment or one or more user equipment groups, determining which one or more user equipment or user equipment groups are impacted by the activation request, and causing a notice to be transmitted to the one or more user equipment or user equipment groups that are impacted.

Abstract: In some example embodiment, there may be provided an apparatus configured to at least: receive information including survival time and/or traffic pattern information indicative of deterministic traffic; determine, based on the received information, a packet handling type indicative of whether the deterministic traffic is to be carried in a selective packet duplication mode or an alternative packet transmission mode over at least two links; and perform, based on at least on the survival time, the indicated packet handling type to enable the deterministic traffic to be carried over the at least two links in the selective packet duplication mode or the alternative packet transmission mode.
