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.

Abstract: Relay service is enabled between a residential gateway and a remote user. For example, a 5G residential gateway (5G-RG) may include a relay user equipment (UE) to enable relay service for a 5G core (5GC)-capable UE behind the 5G-RG to connect to the 5GC. The relay UE of the 5G-RG may provide a trusted/untrusted non-3GPP access network for L2 or L3 transport connection to the 5GC-capable UE.

Abstract: User equipment (UEs) can fallback to a legacy system, such as an evolved packet system (EPS), from a fifth generation system (5GS). For example, a UE camps on the 5GS network by default. When an indicator of a voice call is detected, the UE performs a fallback to EPS for a duration of the voice call. After the voice call, the UE can return to the 5GS. In another example, the UE detects an emergency session request (e.g., internet protocol multimedia subsystem (IMS) emergency session request). The UE performs a fallback to EPS for a duration of the emergency session. After the emergency session is complete, the UE can return to the 5GS. The solution can operate with UEs that operate in either Single Registration (SR) mode embodiments or Dual Registration (DR) mode embodiments. Depending on the embodiment, the UE can perform a handover or redirection to the legacy system (such as E-UTRAN).

Abstract: Disclosed are apparatuses for quality of service (QoS) flow to data radio bearer (DRB) mapping override bits. An apparatus of a user equipment (UE), includes one or more data storage devices, and one or more processors operably coupled to the one or more data storage devices. The one or more data storage devices are configured to store data corresponding to mapping of QoS flows to data radio bearers. The one or more processors are configured to map one or more QoS flows to a DRB in an uplink (UL) responsive to receipt, by the UE from a cellular base station, of a user plane packet in a downlink (DL) through the DRB if an override bit of the user plane packet indicates that reflective mapping should apply.
