摘要： A method for transitioning a video call is provided. The method can include a wireless communication device participating in a video call with a remote communication device via a first video call session established over a connection between the wireless communication device and a first cellular network. The video call can include a packet switched video stream carried over a first bearer and an audio stream carried over a second bearer. The method can further include the wireless communication device determining a degradation in a connection quality for the first cellular network; transitioning to a legacy cellular network having a circuit switched domain in response to the degradation in connection quality for the first cellular network; establishing a second video call session on the legacy cellular network; and using the second video call session to continue the video call on the legacy cellular network.

摘要： Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to antennas. An electronic device may include a baseband processor and other storage and processing circuitry that implements protocol stacks for handling multiple radio access technologies. The storage and processing circuitry may use the transceiver circuitry to convey data using a first radio access technology while periodically interrupting the conveying of the data to monitor a paging channel using a second radio access technology. In performing the paging channel monitoring operations, the storage and processing circuitry may enforce a time limit that ensures that operations using the first radio access technology are not disrupted more than desired.

摘要： The disclosed embodiments provide a system that processes network packets. Upon receiving a first Transmission Control Protocol (TCP) header for a first TCP segment from a network link, the system immediately provides a portion of the first TCP header to a transport layer prior to receiving all payload data for the first TCP segment. Next, the system uses the transport layer to transmit a first acknowledgment of the first TCP segment to the network link, wherein the first acknowledgment reduces a round-trip time (RTT) associated with the first TCP segment.

摘要： In the subject system for Bluetooth audio role-based scheduling, an electronic device (e.g., a mobile phone), may receive streaming audio over a cellular connection, e.g. LTE, and may stream the audio to a head unit of a vehicle, e.g. via Bluetooth. The electronic device may also concurrently communicate with other electronic devices via, e.g., Wi-Fi, Bluetooth, and/or BTLE. The electronic device may determine the Bluetooth/communication capabilities of the HU device, such as buffer size, and the electronic device may proactively configure Bluetooth settings/parameters for communicating with the HU device based on the capabilities of the HU device. The electronic device may also adaptively modify scheduling for communications with other electronic devices based on the determined capabilities of the HU device. In this manner, the electronic device can proactively mitigate and/or prevent the sub-optimal user experience caused by any differences in Bluetooth/communication capabilities of the HU device and the electronic device.
