Abstract: Apparatuses, systems, and methods for QoS impact mitigation during unavailability of RAN support of network slicing, e.g., in 5G NR systems and beyond. A UE may determine, while connected to a first cell of a network, whether handover instructions include DRB setup instructions on a second cell of the network for a PDU session established towards a first network slice on the first cell. The UE may, upon expiration of a timer initiated in response to the determination and/or confirmation that the second cell does not support network slicing, route, upon determining that there is not a neighboring cell that supports the first network slice and/or that there is not a routing rule for the first network slice that allows routing of traffic to another established DRB, user plane traffic to an eMBB DRB.

Abstract: Techniques discussed herein facilitate configuration of network slices for a User Equipment (UE) supporting constraints on simultaneous operation of slices. Such a technique may comprise: receiving a registration request message to request registration on a set of requested network slices;
registering the UE to a set of allowed network slices; and generating a registration accept message for transmission indicating the UE is registered to the set of allowed network slices, wherein the registration accept message indicates slice compatibility information for each allowed network slice of the set of allowed network slices for the UE, wherein the slice compatibility information for each allowed network slice indicates whether or not other configured network slices of a set of configured network slices are compatible with the configured network slice for simultaneous operation by the UE.

Abstract: A mobile device (UE) may access standalone non-public networks (SNPNs) in various different locations as equivalent SNPNs (eSNPNs) corresponding to a home SNPN of the device. The device may obtain a list of eSNPNs corresponding to the home SNPN, and may access a second SNPN at a location different from a location of the home SNPN, in response to identifying the second SNPN and the list including the second SNPN as an eSNPN corresponding to the home SNPN of the device. The eSNPNs may include roaming eSNPNs (ReSNPNs) for accessing an enterprise NPN globally and/or at various different locations. The eSNPN/ReSNPN list may be maintained in a new network identifier management function (NMF). NPNs may be implemented as network slice instances (NSIs) via identifying data in the single network slice selection assistance information (S-NSSAI). Multiple credentialed SNPNs of a UE may be prioritized for access by the UE.

Abstract: Optimizations for simultaneous voice and data experiences in cellular networks include methods of handling voice call fallback, e.g.: (1) on VoNR when an IMS PDU session is established but an Internet PDU session is not yet established; (2) on VoNR when IMS and Internet PDU sessions are established in different network slices; (3) on VoNR when an IMS PDU session is established but a rejection is received for an Internet PDU session; (4) on an LTE network after an EPSFB procedure when an IMS bearer is not present; (5) on an LTE network after an EPSFB procedure when an IMS bearer is present but an Internet bearer is not; (6) on VoNR when a network does not support simultaneous voice and data; (7) when a VoNR-capable UE is camped to SA on a VPLMN; and (8) when a non-VoNR-capable UE is camped to SA on a network that supports VoNR.

Abstract: Methods and devices for selecting an edge application server (EAS) to service a user equipment (UE). One exemplary method incudes determining that a current protocol data unit (PDU) session of an application being executed by a UE is being serviced by a first EAS, determining that the first EAS is no longer suitable to service the application, selecting a second EAS to service the application and instructing the UE to use the second EAS for future PDU sessions for the application.

Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN) dedicated to an international area. The UE receives a downlink message from the NTN, where the downlink message includes a public land mobile network (PLMN) identifier of a first PLMN of the NTN including an information element (IE). The IE indicates that the NTN is dedicated to an international area. Responsive to receiving the downlink message, the UE determines a current location of the UE and determines whether the current location is in the international area. The UE provides an international area notification to an access and mobility management function (AMF) servicing the UE to forward to a home PLMN (HPLMN) of the UE indicating whether the current location is in the international area.

Abstract: Emergency services support is indicated to roaming devices in a wireless network. A user equipment (UE) may receive a message from the wireless network indicating at least one public land mobile network (PLMN) that provides emergency services support for devices in limited service. The UE may store, in a non-volatile memory (NVM), an identifier of the at least one PLMN in a whitelist of limited service emergency services support. In response to a trigger in a roaming limited service condition of the UE, the UE may establish an emergency session with a selected PLMN based on the whitelist of limited service emergency services support.

Abstract: A terminal may include configured to receive, from a network, multiple downlink signals. The terminal may include a processor configured to identify, from the downlink signals, at least one configuration parameter including a bandwidth part switching indicator. The processor may then identify at least one resource from a target bandwidth part indicated by the bandwidth part switching indicator. The processor may then determine a bandwidth part mismatch based on whether a signal is received using the at least one resource from the target bandwidth part.

Abstract: Techniques and wireless devices to perform adaptive measurement object prioritization in a cellular communication scenario. A wireless link is established by the wireless device with a serving cell of a cellular base station. Adaptive measurement object prioritization is implemented responsive to determining that a trigger condition has occurred. A configuration message is received from the base station, where the configuration indicates a plurality of measurement objects including both Long Term Evolution (LTE) and New Radio (NR) measurement objects. A first measurement object of the plurality of measurement objects is selected to prioritize for measurement. The first measurement object is measured during a first measurement gap prior to measuring one or more second measurement objects of the plurality of measurement objects, and a measurement report is provided to the serving cell specifying a measurement result of the first measurement object.
