Abstract:
A device implementing the subject technology may include at least one processor configured to receive an indication of a task being performed at an other device. The at least one processor is further configured to perform, in response to receipt of the indication, one or more preliminary operations in anticipation of receiving a handoff of the task. The at least one processor is further configured to receive, after performing the one or more preliminary operations, a notification that the task is being handed off. The at least one processor is further configured to receive the handoff of the task from the other device. The at least one processor is further configured to continue to perform the task based at least in part on the one or more preliminary operations that were performed prior to receiving the notification that the task is being handed off.
Abstract:
Techniques are disclosed relating to multiway communications. In some embodiments, a first electronic device initiates a multiway call between a plurality of electronic devices and exchanges a first secret with a first set of electronic devices participating during a first portion of the multiway call, the first secret being used to encrypt traffic between the first set of electronic devices. The first electronic device receives an indication that first set of participating electronic devices has changed and, in response to the indication, exchanges a second secret with a second set of electronic devices participating during a second portion of the multiway call, the second secret being used to encrypt traffic between the second set of participating electronic devices. In some embodiments, the indication identifies a second electronic device as leaving the multiway call, and the second secret is not exchanged with the second electronic device.
Abstract:
A unified message delivery between multiple devices is disclosed. Sending messages through a local communications link, such as but not limited to at least one of a Bluetooth connection and a peer-to-peer WiFi connection, can lead to faster transmission times and reduced server load. When the local communications link is unavailable or not suitable, the messages can be sent through a network and a push server. In some examples, messages can be sent through both the local communications link and through the network and the push server. Duplicates of a received message can be avoided by utilizing indicators. In some examples, one or more devices can include queue(s) to ensure ordered delivery of a plurality of messages when a local communications link and network connection become unavailable.
Abstract:
A system and method for conducting a video call between an originating device and a terminating device by establishing a peer-to-peer (P2P) connection between the devices. The originating and terminating devices exchange candidate information through a P2P server, except that the candidate information for the terminating device is altered before arriving at the originating device. The altering includes changing the IP address and corresponding port for each candidate. The originating device uses the altered candidate information to derive new candidate pairs that are sent to the terminating device, which uses the new candidate pairs to also derive a second candidate list. If the candidate pairs match, a P2P connection is established between the devices.
