    Abstract: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform emergency calling. A UE may receive an indication to initiate an emergency call. The UE may select a cell on which to initiate the emergency call. If a serving cell of a first SIM of the UE is not available for the emergency call, the UE may utilize information from a second SIM of the UE as part of selecting the cell on which to initiate the emergency call. The information from the second SIM may include an indication of a serving cell of the second SIM. Alternatively or in addition, the information from the second SIM may include an indication of one or more neighboring cells of the second SIM. The emergency call may be initiated via the selected cell using the first SIM.

    Abstract translation: 用于多SIM用户设备（UE）设备执行紧急呼叫的设备，系统和方法。 UE可以接收到发起紧急呼叫的指示。 UE可以选择在其上发起紧急呼叫的小区。 如果UE的第一SIM的服务小区不可用于紧急呼叫，则UE可以利用来自UE的第二SIM的信息作为选择发起紧急呼叫的小区的一部分。 来自第二SIM的信息可以包括第二SIM的服务小区的指示。 或者或另外，来自第二SIM的信息可以包括第二SIM的一个或多个相邻小区的指示。 可以通过使用第一SIM通过所选择的小区来启动紧急呼叫。

    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: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform system selection. A UE may determine to perform system selection for a first SIM of the UE. Information, such as serving cell and/or neighboring cell information, may be obtained from a second SIM of the UE. System selection for the first SIM may be performed based at least in part on the information obtained from the second SIM.
