摘要： Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.

摘要： 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.

摘要： Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform data operations with a packet data network of a carrier associated with a first SIM of the UE. An indication of a requested data operation with the packet data network of the carrier associated with the first SIM of the UE may be received. The UE may be operating in a dual SIM mode in which the packet data network of the carrier associated with the first SIM of the UE is unavailable. It may be determined if one or more conditions for performing the requested data operation are present and if a data path to perform the requested data operation is available. The requested data operation may be performed if the one or more conditions for performing the requested data operation are present and if a data path to perform the requested data operation is available.

摘要： Apparatuses, systems, and methods for user equipment (UE) devices to perform a radio access technology (RAT) upgrade. A UE may initiate a background scan to upgrade RAT while camped on a first system in response to an occurrence of a first condition. The first system may include a first PLMN that operates according a first RAT. The UE may determine a second system operates according to a second RAT that provides upgraded service as compared to the first RAT. The second system may be included in one or more systems found during the background scan. The UE may attempt to register on the second system based on the second PLMN operating according to the second RAT. The first and second PLMNs may each have an associated operator preference and the first PLMN may be preferred over the second PLMN.

摘要： In order to facilitate communication in a wireless network, an accessibility issue in the wireless network may be detected. For example, if an electronic device is near the boundary between two adjacent cells in the cellular-telephone network, the signal power of signals from a current cell or connection may decrease. Concurrently, the maximum transmit power of the electronic device may be constrained by a thermal limit of the electronic device. When this occurs, the connection may be lost unless remedial action is taken. Therefore, in response to this condition, the electronic device may temporarily increase the maximum transmit power to allow the electronic device to communicate with the cellular-telephone network so that the connection may be transitioned to another cell or connection. In this way, the communication technique may restore the communication performance and avoid a dropped call, which will improve the user experience and customer satisfaction.
