    Abstract: Systems and methods of segregating a SDF of a PDU session are described. The UE transmits a NAS message to the network. The NAS message indicates the SDF, the desired QoS, and a segregation indication that requests that the network establish a separate QoS flow for the SDF even if an existing QoS flow is able to support the specific QoS. The SF decides whether or not to establish the separate QoS flow and updates filters in the UPF as well as providing a response to the UE containing a similar indication. The UE modifies resources related to the PDU session based on the response. The QoS is indicated as a 5QI and GBR or as a QFI of an existing QoS Flow on which the SDF is to be added if the separate QoS is not established. The QFI is in an unencrypted SDAP header of the NAS message.

    Abstract: Systems and methods provide for controlling the derivation of QoS rules in the UE by flexibly defining the scope of packet header fields over which packet filter derivation is performed. The scope of packet header fields for derivation of QoS rules may be provided by the network to the UE upon PDU Session establishment or modification. For PDU Session of IP type, the network indicates to the UE whether the scope of RQoS includes both the Source/Destination IP address pair and the Source/Destination Port numbers, or only the former. For PDU Session of Ethernet type, the network indicates to the UE whether the scope of RQoS includes both the Source/Destination MAC address pair and the IEEE 802.1Q tag, or only the former. The UE may indicate to the network whether it supports the flexible scope of packet filters for RQoS for a PDU session.

    Abstract: IMS emergency call routing techniques are described. In one embodiment, for example, an apparatus may comprise at least one memory and logic for a P-CSCF node, at least a portion of the logic comprised in circuitry coupled to the at least one memory, the logic to cause the P-CSCF node to receive an SIP INVITE message from a roaming UE, the SIP INVITE message associated with an attempt to place an emergency call via an unauthenticated IMS session, the logic to cause the P-CSCF node to obtain a PSAP callback number for the UE from a PCRF node via an Rx interface, identify a PSAP callback parameter for the UE based on the PSAP callback number, insert the PSAP callback parameter into the SIP INVITE message, and forward the SIP INVITE message to a PSAP. Other embodiments are described and claimed.

    Abstract: A user equipment (UE) can include processing circuitry configured to decode system information including access barring parameters for one or more access categories for accessing a cell of a next generation Node-B (gNB). A network access attempt is detected by a control plane layer of the UE that is higher than a Radio Resource Control (RRC) layer. The processing circuitry map s, using a Non-Access Stratum (NAS) layer of the control plane, the network access attempt to at least one access category of a plurality of available access categories based on mapping rules. The processing circuitry performs an access barring check procedure for the mapped at least one access category based on the access barring parameters. Upon determining that access to the cell is not barred, a NAS message is encoded for transmission to an Access and Mobility Management Function (AMF), e.g. an Attach Request message to perform an attach procedure.

    Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB-CU and a gNB-DU. A first paging message for paging of the UE may be received at the gNB-CU from an access management function (AMF) entity. The first paging message may include: a paging identity of the UE; and a paging origin information element (IE) that indicates whether the paging of the UE is originated due to a protocol data unit (PDU) session from non-3GPP access. A second paging message to page the UE may be transmitted from the gNB-DU to the UE. The second paging message may include: the paging identity of the UE; and an access type parameter that indicates whether the paging of the UE is originated due to the PDU session from the non-3GPP access.

    Abstract: Systems and methods of providing 5G access for a UE are generally described. The UE is simultaneously connected via dual radio operation to a legacy and 5G access system. The UE mobility management states for the access systems are independent of each other. The EPC and 5G CN share an HSS and may share a IP anchor. When handover occurs between access systems, the IP address is retained and the IP anchor used when the UE transmits an Attach Request having a Handover Attach Request Type and otherwise a new IP address is provided and the HSS but not the IP anchor is common between the access systems. The 5G eNB to which the UE is connected is standalone and connected to the 5G CN or dual mode and connected with an EPC via an LTE anchor in addition to the 5G CN.
