Abstract: Systems, methods, and devices of the various embodiments provide a multipath communication scheduler for an in-vehicle computing device, such as a vehicle's autonomous driving system, vehicle's telematics unit, vehicle's control system, etc. In various embodiments, a distributed leaky bucket based scheduler for an in-vehicle computing device may assign packets for transport to a plurality of modems based at least in part on the determined delivery delays. In various embodiments, delivery delays may be determined based on leaky bucket levels, burst sizes, delivery rates, and end to end delay estimates for each of the plurality of modems. In various embodiments, the scheduler may be one of a plurality of schedulers each associated with a separate stream of packets assigned to the plurality of modems and the leaky bucket levels may be determined on a per stream basis.

Abstract: Systems, methods, and devices of the various embodiments provide a multipath communication scheduler for an in-vehicle computing device, such as a vehicle's autonomous driving system, vehicle's telematics unit, vehicle's control system, etc. In various embodiments, a centralized scheduler for an in-vehicle computing device may assign packets for transport to a plurality of modems based at least in part on delivery delays associated with the plurality of modems. In various embodiments, delivery delays may be determined based on one or more of queue sizes of the plurality of modems, delivery rate estimates of the plurality of modems, and end to end delay estimates.

Abstract: Techniques for setting up a packet-switched video telephony (PSVT) call are described. A mobile originated (MO) device may transmit an invitation for the PSVT call to a mobile terminated (MT) device. The invitation may initiate a process to reserve and identify video and audio resources to establish the PSVT call. The MO device may determine whether the video resources are available. If the video resources are not available but audio resources are available, the MO device may instead establish the PSVT call with only an audio stream call between the MO device and the MT device. If audio resources become available ahead of video resources, the PSVT call may be established with an audio stream first and a video stream is automatically added to the call when video resources are reserved later, or the PSVT call is downgraded to a VoIP call if the video resources cannot be reserved.
