Content Management Delivery System Local Base Station Multicast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing network traffic due to multimedia content streaming and downloading leads to network overload, resulting in lag and decreased user experience, necessitating efficient management of content distribution to optimize bandwidth usage and reduce congestion.
Innovation Solution
Implementing a content management delivery server that controls the delivery of multimedia content through peer-to-peer routing within wireless networks, allowing eNBs to initiate and support data flows between users without traversing higher network layers, and using unicast or multicast transmission based on content popularity and network conditions to optimize bandwidth utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is delivered through traditional network layers, then content can be managed and controlled by content server modules, but network overload occurs resulting in lag and decreased user experience
Solution Approach 1:
The patent segments the content delivery process by enabling peer-to-peer routing at the base station level, separating the control function (remaining at content server) from the delivery function (distributed to multiple base stations). This segmentation allows local content sharing without traversing higher network layers, reducing congestion while maintaining reliable delivery.
Solution Approach 2:
The patent introduces a new dimension for content delivery by implementing local content sharing at the base station layer. Instead of traditional top-down delivery through core network layers, content can be delivered laterally between base stations serving different cell towers, creating an additional delivery pathway that reduces network overload.
2Adaptability or versatility
If content is streamed to multiple users through traditional network routing, then content can be delivered to individual devices, but network bandwidth is inefficiently utilized
Solution Approach 1:
The patent merges content delivery streams at the base station level by enabling multiple user devices to receive content from a single base station cache. When multiple users request the same content, the base station can serve them locally without requiring separate transmissions through the core network, thus merging bandwidth usage while maintaining delivery flexibility.
Solution Approach 2:
The patent implements content copying at the base station level, where content is cached and replicated locally at base stations serving different geographic areas. This allows users in different locations to receive content from their local base station rather than requiring continuous streaming from remote content servers, reducing overall network bandwidth consumption while maintaining adaptability.
3Extent of automation
If content flows through higher network layers, then centralized content management is maintained, but processing overhead increases and latency increases
Solution Approach 1:
The patent implements preliminary action by pre-caching content at base stations before it is actually needed for delivery. Base stations can proactively store popular content in their local caches, so when users request content, it can be delivered immediately from the local cache rather than requiring real-time retrieval through higher network layers, thus reducing latency while maintaining centralized management control.

AI summary
A method of sharing a streaming content item to a target user equipment (UE) device on a network includes identifying a UE device on the network that is currently receiving the content item. The method determines whether the target and source UE devices are serviced by a common base station. If they are, the method commands the base station to multicast the content item to the UE device and the target UE device. The method also includes sharing a content item stored on a first UE device with a second UE device by commanding the first UE device to send the content item to the second UE device without going through the network or by commanding the first UE device to upload the content item to the base station and then downloading the content item from the base station to the first UE device.
