Patent ID: 11234054

Abstract:
The typical service to deliver multimedia content is evolved Multimedia Broadcast Multicast Service (eMBMS). However, the eMBMS is a service-oriented network architecture requiring a pre-defined and pre-established user service to stream a live video. The content provider must be a multicast service provider to use the eMBMS services, which many typical content providers are not. Accordingly, the present disclosure provides a live video streaming network architecture that enhances the eMBMS architecture to enable service-less multicast delivery. The provided system includes a virtual network function service running on an application server (AS) that identifies potential multicast scenarios based on user requests for a live video stream within a confined area. The AS collects information from the cellular users, checks the information to validate a potential multicast scenario, and transmits the information to the eMBMS core on behalf of the content provider and user equipment to instantiate a multicast resource bearer.
