Abstract: Methods and systems are disclosed for performing seamless voice call handover and data handoff between a cellular network and a non-cellular (e.g., Wi-Fi) network, by a link budget limited user equipment device (UE) in standalone mode. The cellular radio may be maintained in a non-communication mode when not in use, to prevent power and peak power issues that may be unique to link budget limited devices. In response to poor non-cellular performance in support of a voice call, the UE may transition the cellular radio from the non-communication state to an online state. If the cellular network indicates that packet-switched calls are supported, then the UE may initiate handover of the voice call to the cellular network. Various methods for seamless handoff of data communications are also disclosed, in both the presence and the absence of a voice call. Various metrics are disclosed to enhance handoff determinations.

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 client device and a host device may create a local connection for providing wide area network access, such as Internet access, to the client device. In some embodiments, the client device may have limited network capabilities and may not be able to access the Internet without the host device. The client device may provide its speed and direction in a message to potential host devices. A host device may calculate a suitability metric, based on the speed and direction of the client as well as connection properties of the networks, which indicates an ability for the host device to connect the client device to the Internet. The host device may provide the suitability metric within a connection request to the client device. Based on the suitability metric and/or other factors, the client device and the host device may establish the local connection.

Abstract: In some embodiments, a user equipment device (UE) may be configured to perform handover of a communication session from a first packet data network (PDN) to a second PDN. The UE may include a radio and processing circuitry coupled to the radio and configured to interoperate with the radio. The radio may include one or more antennas for performing wireless communications over at least a first packet data network (PDN) (i.e., packet-switched network) and a second PDN. The UE may be configured to communicate over the first PDN according to first context information that was assigned to the UE and initiate a handover operation from the first PDN to the second PDN. In response to initiating the handover operation, the UE may communicate over the second PDN using the first context information for at least a first time duration.

Abstract: An apparatus, system, and method for performing handover of a mobile station (MS) between a base station (BS) and an access point (AP) are described. In one embodiment, the MS may receive one or more threshold values for reporting measurements to the BS. The MS may convert the threshold values to device-specific threshold values. The MS may determine one or more network quality values associated with the AP. The MS may compare the network quality values to the device-specific threshold values. In response to the network quality values exceeding the device-specific threshold values, the MS may convert the network quality values to calibrated network quality values. The MS may provide the calibrated network quality values. The MS may perform handover from the BS to the AP based on providing the calibrated network quality values to the BS.
