Abstract: A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

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: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.

Abstract: A wireless communication system is presented for robust mobility management in a HetNet communication system. A source cell can prepare a macro cell and a target small cell as handover candidates during handover decision making and/or preparation. The mobile device is informed about the prepared macro cell and target small cell using radio resource control (RRC) messaging. After receiving a handover command or detecting radio frequency (RF) loss, the mobile device can try to connect with the target small cell. If the mobile device is unable to connect to the target small cell, the UE can fall back and connect to the macro cell.

Abstract: An electronic device uses one antenna to wirelessly communicate information with two different wireless networks via concurrent connections associated with different radio access technologies. More specifically, the electronic device may receive video via a first of the connections using a multicast communication protocol. In order to maintain the second connection, the electronic device may switch, for a time interval, from the first connection to the second connection during switching events. This switching can disrupt displayed content associated with the video. To prevent this disruption, in response to a trigger that warns of an upcoming switching event, the electronic device accesses a portion of the video in a buffer during the time interval associated with the switching event. When the communication circuit switches back to the first connection after the switching event, the electronic device reverts to the video communication using the multicast communication protocol.

Abstract: In some embodiments, a user equipment device (UE) implements techniques for avoiding conflicts between UE-initiated and network-initiated handovers. In one embodiment, one or more first radios are configured to perform cellular communication using different first and second cellular radio access technologies (RATs) and a second radio is configured to perform wireless communication using a short-range RAT. In one embodiment, the mobile device is configured to, while communicating using the first cellular RAT, in response to determining that an inter-RAT handover to the short-range RAT is likely to be initiated or has been initiated by the at least one processor, delay sending a measurement report to the cellular base station. This delay may avoid conflict between handovers initiated by the network in response to the measurement report (e.g., from the first cellular RAT to the second cellular RAT) and the inter-RAT handover.

Abstract: Estimating loading and potential available throughput a serving cell of a wireless user equipment (UE) device. Physical layer metrics of a channel on which the UE communicates with the serving cell may be measured. Cell utilization of the serving cell may be calculated based at least in part on the measured physical layer metrics. A maximum available throughput of the serving cell may be calculated based on the cell utilization.
