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.

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.
