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 determine that it does not have cellular service and perform one or more searches for a mobile country code (MCC). The searches may include searches based on cellular modes, radio access technologies (RATs), and/or cellular bands. The UE may determine the MCC based on results of the one or more searches and perform a targeted service acquisition search based on, and limited by, the MCC. The MCC may be associated with one or more cellular modes, RATs, and/or cellular bands via a data structure that maps the MCC to the one or more cellular modes, RATs, and/or cellular bands. The targeted service acquisition search may include at least one RAT and one or more cellular bands within the at least one RAT associated with the MCC.
Abstract translation: 用于用户设备（UE）设备的设备，系统和方法，以确定其不具有蜂窝服务并对移动国家代码（MCC）执行一个或多个搜索。 搜索可以包括基于蜂窝模式，无线电接入技术（RAT）和/或蜂窝频带的搜索。 UE可以基于一个或多个搜索的结果来确定MCC，并且基于并由MCC限制的目标服务获取搜索。 MCC可以经由将MCC映射到一个或多个蜂窝模式，RAT和/或蜂窝频带的数据结构与一个或多个蜂窝模式，RAT和/或蜂窝频带相关联。 目标服务获取搜索可以包括与MCC相关联的至少一个RAT内的至少一个RAT和一个或多个蜂窝频带。

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: Techniques are disclosed relating to handover of WLAN voice calls to one or more cellular networks. In some embodiments, a device is configured to perform voice communications over one or more wireless local area networks, communicate with a first network using a first cellular radio access technology (RAT), and communicate with a second network using a second cellular RAT. The device may store, based on communications via the first network, information indicating that the first network does not support voice communications for the apparatus. The device may handover a voice call from a wireless local network directly to the second cellular RAT, based on the stored information and without handover of the voice call to the first cellular RAT, based on call conditions on the wireless local area network.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for de-registration of the wireless device from a first access type over a second access type. Methods also include procedures for maintaining state machines associated with both access types as well as procedures to determine a connection for re-transmitting a de-registration request and to avoid collisions between procedures associated with the first and second access types. Further, methods include an information element configured to indicate which access type has been de-registered.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level.
