Abstract: Techniques to dynamically configure target bitrate for streaming network connections are described. An apparatus may comprise a streaming component operative to establish a streaming network connection with a second client device at a first client device; and a stream configuration component operative to determine inter-arrival rate information for the streaming network connection; provide the inter-arrival rate information to an inter-arrival rate analysis component; receive a preliminary target bitrate from the inter-arrival rate analysis component in response to providing the inter-arrival rate information to the inter-arrival rate analysis component; determine round-trip time information for the streaming network connection; determine an assigned target bitrate and a packet size setting for the streaming network connection based on the preliminary target bitrate and the round-trip time information; and configure the streaming component to perform the streaming network connection with the assigned target bitrate and the packet size setting. Other embodiments are described and claimed.

Abstract: A system, method and apparatus for relaying mobile communications is provided. The system hosts a communication application operated by mobile communication devices. When a communication is received for a user of a destination device that is off-line, the system determines whether the destination device is capable of receiving an unsolicited message (e.g., a push message, a peer-to-peer message). The system then selects a different mobile device capable of sending a peer-to-peer relay message to the destination device. A relay request is transmitted to the selected device, which causes it to generate and transmit toward the destination device a relay message that will cause the destination device to connect to the system. Either or both of the relay device and the destination device may delete the messages it sends and/or receives during this process, before a user of the device opens the message(s).

Abstract: A system and methods are provided for aggregating communication connections. Multiple users connect to a system (e.g., a web-based system) that hosts an application or service for exchanging communications. Users who exchange communications among themselves may be considered “associates.” When one user who is on-line with the application sends a communication through the system for an associate, the system determines whether the associate is on-line or off-line. If the associate is off-line, the system crafts and sends toward the associate a notification regarding the communication, including an address of the communication server to which the one user is connected. When the associate's device receives the notification, the application may attempt to connect to the specified address. In this way associated users' connections will aggregate or gravitate toward the same communication server, thereby eliminating the latency and cost of exchanging users' communications between multiple communication servers.

Abstract: A system, apparatus, graphical user interface and methods are provided for conducting electronic voice communications with status notifications. A user of a first portable device executing a communication application selects a multi-function control that automatically initiates an audio recording, which is automatically sent toward another participant of an active communication session when the control is released. The same multi-function control may be used to transmit a textual message. A representation of the recording is displayed on the user's device, with an indicator that changes appearance when the other participant plays the recording. In addition, when one user initiates an audio recording that will be automatically sent to another user, the other user's device is advised of the initiation of recording and displays that status for the other user.

Abstract: Exemplary embodiments relate to methods and systems for transferring a user's messaging history from one device to another. A user's primary device, storing the official truth of the user's messaging history, establishes an end-to-end encrypted session with a new device, using a first decryption key during initial session setup. The primary device may conglomerate all or a portion of the messages comprising the user's messaging history into a data blob which is encrypted and sent to a blob store. An E2E encrypted message is sent from the primary device to the new device, via an intermediate server. The E2E encrypted message includes a second key for decrypting the data blob and a pointer to the location of data blob on the blob store. The new device retrieves the data blob from the blob store and decrypts the data blob using the second key to extract plaintext versions of the user's messages and adds the messages to the messaging application on the new device. Multiple data blobs may be sent from the primary device to the new device until all or a desired subset of the user's messaging history is present on the new device.

Abstract: Exemplary embodiments relate to techniques for sending ephemeral content messages via a communications service. An interface may be presented to allow a user to initially access ephemeral content functionality and select content for inclusion in the ephemeral content message. The interface may present a streamlined set of use cases without regard to the manner in which the content was initially captured. Different types of content may be used as ephemeral content, including images, videos, weather reports, news stories, text, audio recordings, location tags, etc. The ephemeral content may be sent through the communications service as an end-to-end encrypted message. When a user replies to an ephemeral content message, the reply may trigger a one-to-one conversation between the originating user and the replying user. Alternatively, an ephemeral content message may be initially sent to a selected group, and replies may be sent back to the entire group.

Abstract: Exemplary embodiments are directed to a method for allowing a user at a first client device to provide access to restricted content on a content provider server to a user at a second client device without providing identifying information of the second client device or the user to the content provider. The second client device receives, in a messaging app, a message from the first client device comprising a link to a content item at a content provider and an identifier of a private/public key pair on the second client device. Second client device displays the link in the user interface of the messaging app and receives a user selection of the link. Second client device generates generating a digital signature for the link using the private key of the private/public key pair and sends the link and the digital signature to the content provider. The content item is then received from the content provider and displayed on the second client device.

Abstract: Exemplary embodiments relate to techniques for displaying and interacting with ephemeral content messages in a communication service. Ephemeral content, transmitted as a message in order to preserve end-to-end encryption, may be tagged with an identifier designating the message as an ephemeral content message. A receiving client may recognize the flag and display the content of the message as ephemeral content. The update may include a link to the content that expires under certain conditions. While the link is active, the link may be selected to enter a full-screen presentation of the ephemeral content. Different media types may be associated with different types of full-screen presentations. Displayed ephemeral content from different users may be ranked based on an interest score and displayed in the ranked order. Ephemeral content may be displayed in a user interface on separate tabs.

Abstract: A system, apparatus, and methods are provided for supporting automated recall of a message (e.g., a chat message) from an originator's device, or at least media that accompanied the message. An original message may convey one or more media files that are temporarily stored on a system or apparatus that hosts the communication application used to create, send, and receive messages. The media files may be lost in transit because of failure of a system component, failure of a storage device, purging of the files before they are retrieved by a recipient, or for some other reason. When the recipient's device receives an error in response to an attempt to retrieve the media file(s), it automatically initiates a recall request that is returned to the originating device. If the message and media are still available on the device, an abbreviated version of the message is re-sent, with the media.
