A device implementing the subject technology may include at least one processor configured to receive downlink condition reports from device, each downlink condition report indicating a downlink channel condition of a respective device. The at least one processor is further configured to determine an uplink channel condition for each of the devices. The at least one processor is further configured to determine, for each respective device and based at least in part on the downlink condition reports and the uplink channel conditions, quality tiers, each of the quality tiers indicating a quality of at least one of an audio stream or a video stream. The at least one processor is further configured to provide for transmission, to each respective device, the quality tiers determined for the respective device.

Multi-device communication management

A uniform protocol can facilitate secure, authenticated communication between a controller device and an accessory device that is controlled by the controller. An accessory and a controller can establish a pairing, the existence of which can be verified at a later time and used to create a secure communication session. The accessory can provide an accessory definition record that defines the accessory as a collection of services, each service having one or more characteristics. Within a secure communication session, the controller can interrogate the characteristics to determine accessory state and/or modify the characteristics to instruct the accessory to change its state.

Uniform communication protocols for communication between controllers and accessories

Some embodiments provide a method for initiating a video conference using a first mobile device. The method presents, during an audio call through a wireless communication network with a second device, a selectable user-interface (UI) item on the first mobile device for switching from the audio call to the video conference. The method receives a selection of the selectable UI item. The method initiates the video conference without terminating the audio call. The method terminates the audio call before allowing the first and second devices to present audio and video data exchanged through the video conference.

Establishing a video conference during a phone call

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.

Secure multiway calling

A device implementing the subject technology may include at least one processor configured to transmit an allocation request requesting allocation of a group communication session with a plurality of devices and receive an allocation response in response to the allocation request, the allocation response including credential information for the device to use to join the group communication session. The at least one processor may be further configured to transmit an allocation bind request with the credential information to join the group communication session using the credential information and receive an allocation bind success response in response to the allocation bind request, the allocation bind success response indicating that the device has joined the group communication session. The at least one processor may be further configured to provide a join notification to the plurality of devices via an intermediary device to notify that the device has joined the group communication session.

The subject technology provides a video conferencing application in which a live incoming or outgoing video stream can be supplemented with supplemental content, such as stickers, animations, etc., from within the video conferencing application. In this manner, a user participating in a video conferencing session with a remote user can add stickers, animations, and/or adaptive content to an outgoing video stream being captured by the device of the user, or to an incoming video stream from the device of the remote user, without having to locally cache/store a video clip before editing, and without having to leave the video conferencing session (or the video conferencing application) to access a video editing application.

Modifying video streams with supplemental content for video conferencing

The subject technology provides a messaging application in which an image can be captured and supplemented with supplemental content such as stickers, animations, etc., from within an active messaging thread. In this manner, a user participating in a messaging conversation with a remote user can add stickers, animations, and/or adaptive content to an image captured by the user, without having to locally cache/store the captured image before editing and without having to leave the messaging conversion (or the messaging application) to access an image editing application.

Modifying images with supplemental content for messaging

Establishing a communication channel via a relay server with reduced setup time. Upon request by an initiating communication device a relay allocation server may allocate a single relay server for use in a communication session between the initiating communication device and one or more recipient communication devices. The relay server may be selected to perform favorably for the initiating communication device. Messaging for establishment of the communication session may be performed using persistent messaging connections, to avoid connection establishment cost. Messaging may also be performed using address tokens to avoid the cost of discovering global IP addresses. Following establishment of the communication session, the relay server may discover the IP address of one or more recipient communication devices, and may initiate reallocation of those devices to another relay server.

Relayed communication channel establishment

A quick relay communication protocol is used by an initiating communication device (such as a wearable electronic device, e.g., a smart watch) and/or a recipient communication device (such as a companion electronic device to the wearable electronic device, e.g., a smart phone, a tablet computer or a laptop computer) to selectively communicate messages via different communication channels. Based on available connections and a communication constraint associated with a message, a processor executing a program module in an application layer in the initiating communication device provides transmission instructions to an interface circuit in the initiating communication device, which transmits a message to the recipient communication device based on the transmission instructions. When there are currently no available connections and the message is eligible to be communicated through a cloud-based relay server, the processor establishes a cloud-based connection with the recipient communication device via the relay server.
