摘要： Embodiments herein provide apparatuses and techniques for providing a notification indicating guidance to reaching cellular connectivity in the event of a loss of cellular connectivity and for guiding a user of a user equipment to a location with cellular connectivity. The notification may be generated based on expiration of a timer, a screen unlock operation, or an application connection failure. The notification may indicate how long ago the cellular connectivity loss occurred and how far away a nearest location is with a cellular connectivity was. The user equipment may display a map interface based on user input selecting the notification. The map interface may show a map of the current location of the user equipment, a nearest location with cellular connectivity to the user equipment, and a path, which includes a tracked path of user equipment and a proposed path to the nearest location with cellular connectivity.

摘要： A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

摘要： Apparatuses, systems, and methods for a wireless device to perform negotiation of bearer type configuration and/or related parameters. A user equipment device (UE) and/or network may determine a bearer configuration and/or other parameters based on information or measurements of the UE. The UE and the BS may exchange data using a negotiated configuration.

摘要： A system and method for operation of a user equipment (UE) to determine a cellular network bottleneck in a downlink channel, and an apparatus for use in a UE for determining the same. A UE may determine a burst of network traffic from network traffic received from the cellular network during a series of transmission time intervals. The UE may analyze resource allocations to the UE during the burst to determine an extent to which the cellular network is busy. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the analysis of the resource allocations to the UE in the burst.

摘要： A method for playing a movie asset in several playback devices. The method receives a request to play a movie asset and synchronizes clocks between a first device and a second device, which is a portable device. The method signals a start of the playback of the asset through the first and second playback devices, where playback on the second device is synchronized with playback on the first device. The method wirelessly transmits an alert message that identifies the asset through the first and second devices and includes a description of an upcoming or future segment of the asset, where a first version of the segment is played back through the first device. In response to receiving the alert message, the second device becomes configured to select a second version of the segment in accordance with i) user settings of the portable device and ii) the description of the segment.

摘要： A device, system and method for initiating cell selection. The method is performed at a device connected to a network and camped on a first cell of the network. The method includes determining whether the device has successfully synchronized with the first cell. When the device is unable to synchronize with the first cell, the method includes determining whether at least one further cell satisfies predetermined reselection criteria and determining whether the at least one further cell satisfies initial cell selection criteria. When the at least one further cell satisfies the initial cell selection criteria, the method includes initiating an initial cell selection.

摘要： A system and method for selecting a network interface for a communication device having at least two radio physical interface, to improve communications by the communication device. A configuration of the communication device is determined, where a first radio physical interface is designated as a primary interface and active, and a second radio physical interface as idle. A networking subsystem of the operating system executes a state machine configured to monitor network conditions and associated performance parameters of the at least two radio physical interfaces, to automatically outrank the second radio physical interface over the first radio physical interface as the primary interface.
