Dynamic Content Distribution Area Adjustment via User Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile broadcast and multicast systems inefficiently distribute content as they use fixed radio modulation schemes and centrally determined content distribution areas, leading to wastage of network resources and suboptimal user experience.
Innovation Solution
Implementing a user feedback-based content distribution system that dynamically adjusts content distribution areas based on user preferences and location, using a user preference analytics server to select and schedule content, and dynamically grow or shrink content distribution areas based on user interest, thereby targeting content delivery only to interested users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed radio modulation schemes and centrally determined content distribution areas are used, then unified decoding and simplified system operation are achieved, but network resource efficiency deteriorates and user experience quality deteriorates
Solution Approach 1:
The system implements feedback mechanisms where user equipment sends channel quality indicators and content preference information back to the network. The network controller uses this feedback to dynamically adjust modulation and coding schemes (MCS) and to determine optimal content distribution areas, transforming the fixed centralized control into an adaptive system that responds to real-time conditions while maintaining operational simplicity.
Solution Approach 2:
The patent transforms the static fixed modulation scheme and fixed content distribution area into dynamic parameters. The system continuously adjusts MCS based on channel conditions and dynamically determines content distribution areas based on user location and content preferences, allowing the system to adapt to changing conditions while preserving ease of operation through automated control.
2Reliability
If fixed radio modulation schemes are used, then unified decoding is achieved, but adaptability to different channel conditions deteriorates
Solution Approach 1:
The system changes the modulation and coding scheme parameters dynamically based on channel quality indicators received from user equipment. The network controller selects appropriate MCS from a set of predefined schemes, adjusting parameters like modulation order and code rate to match current channel conditions while ensuring unified decoding capability across the network.
3Device complexity
If centrally determined content distribution areas are used, then simplified content distribution control is achieved, but network resource utilization deteriorates
Solution Approach 1:
The system uses feedback from user equipment regarding content preferences and location information to dynamically determine content distribution areas. The network controller processes this feedback and configures base stations to broadcast content only in areas where interested users are located, optimizing network resource utilization while maintaining simplified centralized control architecture.
Solution Approach 2:
The patent segments the content distribution area into multiple regions based on user location and content preference feedback. Different base stations are configured to serve different segments, allowing targeted content delivery to specific geographic areas rather than blanket coverage, thereby improving network resource utilization.
4Ease of operation
If content is distributed to all areas, then all users can access content uniformly, but network resource waste increases
Solution Approach 1:
The system applies local quality by configuring different base stations to broadcast different content in different geographic areas based on local user preferences and location. Each content distribution area is optimized for its specific user base, delivering content uniformly to users within that local area while avoiding waste in areas where the content is not desired.
Data Source
AI summary
A method includes providing, to a user device, an identification of a superset of potential video programs that are available to be scheduled for multicast to a content distribution area that includes a cell associated with the user device. The method also includes receiving a selection of a subset of the potential video programs from the user device and a location associated with the user device. The method further includes generating at least one content distribution area based on the location of the user device and the selection of the subset of the potential video programs.
