Abstract: Adaptive out-of-service search behavior by a wireless user equipment (UE) device. The UE may perform cellular communications according to a radio access technology (RAT). It may be determined that cellular service according to the RAT is not available. A search algorithm may be selected from at least two possible search algorithms. A search for cellular service according to the RAT may be performed according to the search algorithm. The various possible search algorithms may specify different ratios of time spent scanning for cellular service to time spent sleeping. The selected search algorithm may be chosen based on any or all of an estimated remaining battery life of the UE, a user activity level, user input, or various other considerations.

Abstract: Cell re-selection in a device configured to operate according to multiple cellular communication protocols. The device may operate according to a first cellular communication protocol at a first time, which may include attaching to a first cell. The device may operate according to a second cellular communication protocol at a second time. Operations according to the first cellular communication protocol may be suspended while operating according to the second cellular communication protocol. The device may attempt to resume operating according to the first cellular communication protocol at a third time. This may include measuring one or more of signal strength or signal quality of the first cell. The wireless device may select a cell to which to attach at the third time based at least in part on the measured signal strength and signal quality of the first cell.

Abstract: Methods and apparatus for resolving incomplete message content in networks. Various embodiments of the present disclosure are directed to correction and recovery of incomplete measurement report configuration messages within a Long Term Evolution (LTE) network. Specifically, within certain LTE networks, existing messaging may be incomplete in regards to various nearby ancillary networks, but still sufficient with regards to measurement requirements of the LTE network itself. Since the mobile device can continue operation within the LTE network, the mobile device can safely ignore or correct the measurement report configuration message.

Abstract: A method for reducing call drops in uplink power limited scenarios is disclosed. The method can include a wireless communication device determining that the wireless communication device is experiencing an uplink power limited condition in which a transmission power of the wireless communication device is limited to a level below a power class level of the wireless communication device. The method can further include defining a downlink power threshold for sending a measurement report for triggering a handover based on the uplink power limited condition. The downlink power threshold can be higher than a threshold configured by a serving base station. The method can additionally include determining based on measured downlink power that the calculated downlink power threshold is satisfied and sending a measurement report for triggering a handover to the serving base station in response to the downlink power threshold being satisfied.

Abstract: Methods and apparatus for power optimization in e.g., a wireless mobile device. In one embodiment, the optimization is effected via intelligent idle mode current drain management. In an exemplary LTE cellular network context, the user equipment (UE) only powers on its transceiver for a subset of Discontinuous Reception (DRX) cycles based on e.g., the quality of the radio environment, power considerations, location, etc. For example, if a UE has not moved, and its radio reception quality is good, the UE is likely to successfully receive a paging notification (i.e., without multiple attempts). Consequently, the UE configures itself to receive only a single paging indication.
