Multicast Subscriber Server for Mobile Video Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks face challenges in efficiently delivering video content to multiple mobile devices, as unicast transmissions require multiple channels dedicated to each device, whereas multicast systems may strain the network with limited control over content providers and user participation.
Innovation Solution
The implementation of a Multimedia Broadcast Multicast Service (MBMS) over a Long Term Evolution (LTE) network, allowing users to upload and share content via multicast transmission, where interested users can register to receive and view content at their convenience, utilizing a multicast subscriber server and network components like the Broadcast Multicast Service Center and MBMS Gateway to manage and distribute the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unicast transmission is used to deliver video content to multiple mobile devices, then each device receives dedicated content delivery, but the network requires multiple channels which increases network strain and reduces bandwidth efficiency
Solution Approach 1:
The patent merges multiple unicast transmission channels into a single multicast channel. Instead of establishing separate dedicated channels for each mobile device receiving video content, the system combines these into one shared multicast channel that can deliver content to multiple devices simultaneously, thereby reducing network strain while maintaining reliable content delivery to all subscribers
2Productivity
If multicast transmission is used to reduce network strain, then bandwidth efficiency improves, but the system lacks control over content providers and user participation
Solution Approach 1:
The patent introduces a multicast subscriber server as an intermediary between mobile devices and the multicast transmission system. This server manages content provider registration, handles user subscription requests, and controls participation in multicast groups. By placing this intermediary layer, the system maintains efficient multicast bandwidth usage while regaining control over who can provide content and who can receive it, thus resolving the control complexity issue
3Productivity
If traditional multicast systems are used, then network strain is reduced, but user convenience and content sharing capabilities are limited
Solution Approach 1:
The patent enables mobile devices to act as both content consumers and content providers through the multicast system. Users can independently register their devices to receive multicast content, upload their own video content to be shared via multicast, and manage their subscriptions without requiring complex manual configuration. This self-service capability enhances user convenience while the system continues to utilize efficient multicast transmission for content delivery

AI summary
Content originated by a mobile device may be transmitted, via multicast, to one or more other mobile devices. In one implementation, a method may include receiving, from a mobile device attached to a wireless network, a request to initiate a multicast transmission of content generated by the mobile device. The method may further include determining one or more wireless coverage areas to which the multicast transmission of the content is to be provided; receiving, from the mobile device, a unicast transmission of the content; and distributing the received content, via one or more multicast data channels that are broadcast in the one or more wireless coverage areas.
