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: 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: A user equipment (“UE”) connected to a first network that performs methods including receiving a page from the first network indicating an incoming voice call, when it is determined the voice call was not successfully connected, incrementing a value of a counter and when the value satisfies the threshold, switching from the first network to a second network. Another method includes originating a voice call via the first network, when it is determined the voice call was not successfully connected, opening a socket connection with the first network and attempting to re-originate the voice call via the first network. Another method includes determining whether the UE has switched a connection from a first network to a second network and when it is determined that the UE has switched the connection to the second network, initiating an action by the UE.

Abstract: This disclosure relates to techniques for a wireless device to detect network bandwidth throttling and dynamically select a buffer threshold. The wireless device may establish a wireless link. Data for a downlink stream may be requested when an amount of buffered data for the stream is below a lower buffer threshold, received via the wireless link, and buffered. Data requests for the stream may be stopped when the amount of buffered data for the stream is above an upper buffer threshold. The upper buffer threshold may be selected based on characteristics of the wireless link and the stream. Throughput of the wireless link may also be monitored during multiple time windows, and the wireless device may determine whether the wireless link caps bandwidth below a bandwidth threshold based on the throughput monitoring.
