Abstract:
An electronic device that at least semi-automatically performs car-key pairing is described. During operation, the electronic device may perform wireless pairing with a second electronic device (e.g., a vehicle), where the wireless pairing establishes a connection between the electronic device and the second electronic device. Moreover, during the wireless pairing, the electronic device may receive information associated with the car-key pairing of the electronic device and the second electronic device. Then, after the wireless pairing is completed, the electronic device may determine that the car-key pairing is supported or available based at least in part on the information. Next, the electronic device may selectively and at least semi-automatically perform the car-key pairing based at least in part on the information, where the car-key pairing enables the electronic device to function as a digital key for the second electronic device using wireless communication via the wireless pairing or another communication protocol.
Abstract:
During operation, an electronic device may provide, to a second electronic device, an invitation to share a digital car key associated with a user of the electronic device and a vehicle, where the invitation includes information for creating another instance of the digital car key on the second electronic device. Then, the electronic device may receive, from the second electronic device, a message accepting the invitation, where the message includes a certificate associated with the other instance of the digital car key on the second electronic device. Moreover, the electronic device may provide, to the second electronic device, an approved version of the certificate with a digital signature of the user. Next, the electronic device may provide, to the computer, an instruction to share the digital car key with a set of electronic devices, which is associated with a second user of the second electronic device.
Abstract:
A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. In prior art designs, the instantaneous jitter is derived from a weighted history of the media stream, and consequently only packets that have already arrived are used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay—for packets that have not yet arrived—may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.
