Abstract: This Application describes efficient cellular service transfer mechanisms to move cellular services that are based on cellular service credentials, e.g., eSIMs, between accessory wireless devices under various scenarios, including in some embodiments transfer of multiple eSIMs. The first and second accessory wireless devices and the primary wireless device are associated with a common user account. Transfer of credentials for cellular service access can occur between two accessory wireless devices via the primary wireless device, where the primary wireless device and the accessory wireless devices interact with applicable network-based servers.

Abstract: A user equipment (UE), base station and a corresponding method for receiving historical data from a diagnostic server, receiving location data of the UE, determining a probability of a failed handover during a call based on the historical data and the location data, comparing the probability of the failed handover to a threshold value and initiating a call handover to a wireless local area network when the probability of the failed handover exceeds the threshold value. Also, a UE, base station and corresponding method for determining if one or more UEs have an active voice over WiFi call or if the UEs are registered with a Internet protocol (“IP”) multimedia subsystem (“IMS”) over WiFi and biasing a cell reselection procedure of the UE to select a cell of a packet switched network such as LTE.

Abstract: Some embodiments relate to a smart phone or a wearable device, such as a smart watch, and associated methods for enabling the UE device to switch from a normal mode to/from a voice-to-text mode and/or a text-to-voice mode. The transition to/from voice-to-text mode and/or text-to-voice mode may be conducted automatically or through manual selection by the user of the UE. These transitions (or the presentation of a manual selection option) may be determined based on an ambient noise measurement performed by the UE.
