Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular broadcast systems are not configured to provide the full range of terrestrial broadcast television services, requiring cross-technology service delivery migration to support broadcast TV services over cellular networks.
Innovation Solution
Configuring network elements of the cellular broadcast system to include transport and application-related signaling information from terrestrial broadcast TV services, enabling the delivery of these services by modifying user service descriptions and adding relevant metadata to existing or new service description elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular broadcast systems use their native service delivery configuration, then system simplicity is maintained, but the full range of terrestrial broadcast television services cannot be provided
Solution Approach 1:
The cellular broadcast system is configured to support both native cellular broadcast services and terrestrial broadcast television services through a unified service delivery mechanism. The system can function as a cellular broadcast network while simultaneously delivering terrestrial TV services by integrating transport and application signaling from both systems, enabling multi-functionality without requiring separate infrastructure.
Solution Approach 2:
A service description configuration mechanism acts as an intermediary layer between terrestrial broadcast TV services and cellular broadcast delivery. This intermediary translates and adapts terrestrial broadcast signaling (transport and application layers) into cellular broadcast system parameters, enabling service migration without direct exposure of terrestrial service complexities to the cellular network infrastructure.
2Adaptability or versatility
If terrestrial broadcast TV services are migrated to cellular broadcast networks, then spectrum reuse is enabled, but cross-technology service delivery complexity increases
Solution Approach 1:
The system changes key parameters of the service delivery by mapping terrestrial broadcast TV service parameters (frequency, modulation, signaling protocols) to cellular broadcast network parameters (resource blocks, transport channels, signaling messages). This parameter transformation enables spectrum reuse and service migration while managing complexity through systematic parameter adaptation rather than architectural redesign.
Solution Approach 2:
The service migration process is segmented into distinct layers: transport signaling extraction from terrestrial services, application signaling adaptation to cellular protocols, and service description configuration in the cellular network. This segmentation allows each layer to be configured independently, reducing overall cross-technology integration complexity.
3Reliability
If native terrestrial broadcast signaling is integrated into cellular broadcast systems, then service compatibility is improved, but information element configuration complexity increases
Solution Approach 1:
The system copies essential information elements from terrestrial broadcast TV service descriptions and integrates them into cellular broadcast service descriptions. Rather than redefining all signaling parameters, key elements (service identifiers, transport parameters, application metadata) are copied and adapted to cellular protocols, ensuring service compatibility while minimizing configuration complexity through selective replication.
