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: Apparatuses, systems, and methods for user equipment (UE) devices to more efficiently scan frequency bands for potential base stations may include a UE configured maintain a first list of cells for which a cellular scan has been successful and a second list of cells for which a cellular scan has not been successful. The UE may be configured perform a first cellular while camped on a first cell at an expiration of a scan timer and, if the cellular scan is not successful, the increment a first failure count variable associated with the first cell and add the first cell to the second list if the first cell is not present on the first or second list. Additionally, if the first cellular scan is successful, the UE may be configured to add the first cell to the first list if the first cell is not present on the first list.

Abstract: In order to improve the management of the power consumption of electronic devices (such as cellular telephones), the operating mode of an interface circuit in an electronic device may be changed when certain commands are received. In particular, when one or more commands are received that disable data communication via the interface circuit and a cellular-telephone network and/or enable communication via another interface circuit in the electronic device and a wireless local area network (WLAN), the interface circuit may be transitioned to an operating mode in which data communication via the cellular-telephone network using a communication protocol that supports only data and no voice is disabled. For example, the communication protocol may include a Long Term Evolution (LTE)-compatible communication protocol.

Abstract: Methods and apparatus for reducing voice call drop rate. 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.
