eMBMS Network Controller for Location-Based Multicast Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multicast communication in wireless systems faces limitations in reliability and efficiency, necessitating improvements in how broadcast and multicast services are managed and optimized for user preferences and location-based data distribution.
Innovation Solution
A network controller directs broadcast and multicast communications by receiving user preference and location information from user equipment devices, selecting appropriate data packages for transmission, and providing indications to remote devices for efficient data distribution using enhanced multimedia broadcast multicast services (eMBMS), which enables intelligent content selection and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multicast communication is implemented in wireless systems, then data transmission efficiency is improved, but reliability deteriorates
Solution Approach 1:
The patent segments the multicast service area into multiple broadcast regions based on user location information. The network controller divides the large-scale multicast group into smaller regional groups, allowing independent management and transmission for each region. This segmentation improves reliability by ensuring that transmission failures in one region do not affect other regions, while maintaining overall system efficiency through parallel transmissions.
Solution Approach 2:
The patent applies local quality by customizing broadcast region selection and data package transmission based on specific local conditions. User preference information and location data are used to determine which regions receive which data packages, allowing each region to receive optimized content tailored to local user demands. This resolves the contradiction by improving reliability through localized error correction and maintaining efficiency through targeted transmissions.
2Productivity
If broadcast regions are selected based on user preference and location information, then service efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by having user equipment devices pre-submit preference information and location data to the network controller before actual data transmission. The network controller uses this advance information to pre-calculate and determine optimal broadcast region selections and data package allocations. This preliminary processing simplifies the real-time transmission process while maintaining high service efficiency, as the complex decision-making occurs in advance rather than during active transmission.
3Ease of operation
If data packages are selected based on user preference information, then user experience is improved, but information processing requirements increase
Solution Approach 1:
The patent extracts only the essential preference information and location data from user equipment devices that are necessary for broadcast region selection and data package determination. The network controller processes only these key parameters rather than all possible user data, thereby improving user experience through personalized service while minimizing information processing load by extracting and using only the most relevant information for decision-making.
Data Source
AI summary
A network controller, a user equipment (UE) device, and associated methods for conducting intelligent enhanced multimedia broadcast multicast services (eMBMS). A network controller receives user preference information and location information from a plurality of UEs. The network controller selects one or more data packages to transmit using eMBMS in one or more broadcast regions based on the user preference information and the location information. The one or more data packages may comprise an updated machine learning model in a distributed learning application. The network controller provides an indication to a remote device to broadcast the one or more data packages in the respective one or more broadcast regions using eMBMS.
