US 11689383

US Patent 11689383, titled "System, method, and computer-readable medium for streaming real-time data from a user device," was filed on September 13, 2022, and issued on June 27, 2023. The patent is currently assigned to Carbyne Ltd and lists Alexander DIZENGOF as the inventor.

Abstract:
The patent describes a method for streaming real-time video from a mobile device during an emergency call without requiring a full application download. This involves obtaining the mobile device's phone number during an emergency call conducted over a first connection. A URL link is then transmitted to the mobile device via an electronic message (a second, different connection) using the phone number. When the user clicks this URL, it opens a web browser to establish a WebRTC (Web Real-Time Communication) session for transmitting a real-time video stream. The URL is associated with the phone number. The system receives this real-time video stream through the WebRTC session and sends it to the recipient (e.g., an emergency call center) for display, while audio content of the emergency call is still received through the first connection. The real-time video stream is associated with a unique identifier for the mobile device.

Independent Claims Overview:

• Independent Claim 1 (Method): This claim outlines a method involving several steps. First, it obtains the phone number of a mobile device engaged in an emergency call, where the call is established with a recipient via a "first connection." Next, a URL link is sent to the mobile device through an electronic message (such as a text message) over a "second connection," which is distinct from the first. This electronic message is configured such that a user clicking the URL link will open a web browser on their mobile device—rather than a dedicated application—to initiate a WebRTC session. This WebRTC session is used to transmit a real-time video stream from the mobile device. The URL link is uniquely tied to the mobile device's phone number. Subsequently, the method involves receiving this real-time video stream via the WebRTC session and then sending it to the recipient for display. Crucially, the real-time video stream is received through the WebRTC session concurrently with the audio content of the emergency call being received through the first connection, and the video stream is linked to a unique identifier for the mobile device.

• Independent Claim 8 (System): This claim describes a system that performs the actions outlined in Claim 1. The system comprises processing circuitry and a non-transitory computer-readable medium. This medium stores computing instructions that, when executed by the processing circuitry, enable the system to: obtain a mobile device's phone number during an emergency call over a first connection; transmit a URL link via an electronic message (second, different connection) to the mobile device, allowing a user to click it to access a web browser (not a full application) to establish a WebRTC session for real-time video streaming, with the URL linked to the phone number; receive the real-time video stream through the WebRTC session; and send the video stream to the recipient for display, ensuring the video is received via WebRTC while audio comes through the first connection, and associating the video with a unique identifier for the mobile device.

• Independent Claim 15 (Non-transitory Computer-Readable Medium): This claim defines a non-transitory computer-readable medium that stores instructions. When these instructions are executed by processing circuitry, they cause the processing circuitry to perform the same method steps as described in Claim 1. Specifically, the instructions enable obtaining a mobile device's phone number during an emergency call over a first connection; transmitting a URL link via an electronic message (second, different connection) to the mobile device, allowing a user to click it to access a web browser (instead of a full application) to establish a WebRTC session for real-time video streaming, with the URL linked to the phone number; receiving the real-time video stream through the WebRTC session; and sending the video stream to the recipient for display, while ensuring the video is received via WebRTC concurrently with audio from the first connection, and associating the video with a unique identifier for the mobile device.
