Abstract: Generating and using a device-type specific preferred public land mobile network (PLMN) list for roaming PLMN selection. Wireless devices sharing one or more common characteristics may be tasked with collecting roaming PLMN selection data. That data may be collected and used to generate a preferred PLMN list specific to wireless devices sharing those common characteristics. The preferred PLMN list may be distributed to wireless devices sharing those common characteristics, which may then use it in conjunction with roaming PLMN selection.

Abstract: Described herein are methods performed by user equipment (“UE”) for carrier aggregation deployment and organization in unlicensed bands. The method includes initiating a cell selection process with a target cell, wherein the target cell sends a plurality of information blocks, receiving a first information block, prior to reading a second information block, determining whether the target cell is suitable for the UE to camp on based on the first information block, and terminating the cell selection process when the target cell is determined to be unsuitable for camping based on the first information block. The terminating may include comparing data from the first information block to data stored in a database. The method further includes determining whether the UE is in a stationary state or is in a state of motion, and using this information to improve cell selection delay on target cell.

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to more efficiently scan frequency bands for potential base stations may include a UE configured to store information regarding results of prior cellular scan operations for a cell and to perform a new cellular scan operation while camped in the first cell. The new cellular scan operation may be partially based on the stored information. The prior cellular scan operations may have been performed to identify frequencies of available cellular base stations. The UE may update the information regarding results of prior cellular scan operations with information regarding success or failure of the new cellular scan operation. The UE may maintain lists of cells for which a cellular scan has been successful or unsuccessful and adjust the new cellular scan operation based at least partially on contents of at least one of these lists.

Abstract: Methods and apparatus for reducing voice call drop rate are disclosed. Existing devices do not account for the added burden of background services on voice calls. Specifically, multi-RAB scenarios (e.g., a voice call and background services) can experience significant reduction in call quality. Accordingly, in one exemplary embodiment, background services that are not time-critical and/or application-critical can be suspended while a voice call is in progress. By suspending background traffic during a call, the device can avoid unnecessary multi-RAB voice call operation, which significantly improves overall network operation and user experience.
Abstract translation: 公开了用于降低语音呼叫丢弃率的方法和装置。 现有设备不会影响后台服务对语音通话的负担。 具体地，多RAB方案（例如，语音呼叫和后台服务）可以显着降低呼叫质量。 因此，在一个示例性实施例中，在进行语音呼叫时可以暂停不是时间关键和/或应用关键的后台服务。 通过在呼叫期间挂起后台流量，设备可以避免不必要的多RAB语音呼叫操作，大大提高了整体网络运行和用户体验。
