Abstract: A method performed by a user equipment (UE) connected to a first home cell of a home public land mobile network (HPLMN). The method includes determining a type of the first home cell, when the type is a first type, determining a first quality of the connection to the first home cell, in response to the first quality not satisfying a first predetermined threshold or a determination that the type is a second type, disconnecting from the HPLMN, connecting to a first visited cell of a visited public land mobile network (VPLMN), determining a second quality of the connection to the first visited cell and when the second quality of the connection to the first visited cell is above a second predetermined threshold, performing a data exchange via the first visited cell.

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform more efficient frequency scans for potential base stations. According to techniques described herein, the UE may determine that it does not have cellular service and determine first information based on a last camped cell. A time period during which the first information was acquired may be determined and one or more frequency scans may be performed. The frequency scans may be limited to a set of frequencies based in part on the time period. Thus, if the time period is less than a first value, the set of frequencies may include a first set of frequencies and if the time period is greater than the first value but less than a second value, the set of frequencies may include the first set of frequencies and a second set of frequencies.

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a radio access technology (RAT) upgrade. A UE may initiate a background scan to upgrade RAT while camped on a first system in response to an occurrence of a first condition. The first system may include a first PLMN that operates according a first RAT. The UE may determine a second system operates according to a second RAT that provides upgraded service as compared to the first RAT. The second system may be included in one or more systems found during the background scan. The UE may attempt to register on the second system based on the second PLMN operating according to the second RAT. The first and second PLMNs may each have an associated operator preference and the first PLMN may be preferred over the second PLMN.
Abstract translation: 用于用户设备（UE）设备执行无线电接入技术（RAT）升级的设备，系统和方法。 响应于第一状况的发生，UE可以启动后台扫描以升级RAT，同时驻留在第一系统上。 第一系统可以包括根据第一RAT操作的第一PLMN。 UE可以根据与第一RAT相比提供升级服务的第二RAT来确定第二系统操作。 第二系统可以被包括在在后台扫描期间发现的一个或多个系统中。 UE可以基于根据第二RAT操作的第二PLMN来尝试在第二系统上注册。 第一和第二PLMN可以各自具有相关联的运营商偏好，并且第一PLMN可以优于第二PLMN。

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform capability updates. Under at least some circumstances, the UE may use a non-cellular (e.g., non-3GPP) access to transmit updated capability information to a cellular network. Elements of the core of the cellular network may provide an identifier corresponding to the updated capability information to the UE for use in future registrations with the cellular network. Further, the core network may provide the updated capability information to a cellular radio access network associated the cellular network. The UE and the cellular network may communicate according to the updated capability.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE), manufacturer server, and/or cellular network to perform radio capability signaling. A new type of UE radio capability identifier is provided which may allow a network to distinguish between similar UEs that have or have not implemented a capability update. In order to perform a forced capability update, a manufacturer may issue information about the update to a cellular network (and receive acknowledgement of the information) prior to pushing the update to UEs. In response to an unforced capability update, a cellular network may maintain multiple UE radio capability identifiers for similar UEs which have or have not implemented the update. A UE radio capability identifier may be adjusted dynamically in response to temporary changes in the UE's capability.

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: Apparatuses, systems, and methods for a wireless device to perform detection and mitigation of data stalls. The mitigation may occur during and/or at initiation of a data connection. The wireless device may establish a data connection(s) with a network over a Wi-Fi or cellular interface and monitor the data connection(s) for a data stall condition(s)/hint(s). The wireless device may perform a remedial action(s) responsive to detection of a data stall condition(s)/hint(s), including initiating a service recovery of the cellular interface, initiating a radio access technology (RAT) upgrade procedure, and/or initiating a handover procedure to a neighbor cell.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to prioritize cells that support EN-DC over similar cells not supporting EN-DC. The UE may be configured to perform one or more measurement scans associated with cell selection and/or cell re-selection and may determine whether at least two LTE cells meet a selection criteria based on RSRP and/or SNR measurements. The UE may be configured to, in response to determining that at least two LTE cells meet the selection criteria, prioritize a first LTE cell of the at least two LTE cells over a second LTE cell of the at least two LTE cells based, at least in part, on support EN-DC. The first LTE cell may indicate support of EN-DC, e.g., via a ULI IE included in a SIB2 broadcast by the first LTE cell. The UE may be configured to select the first LTE cell for camping.
