Mobile Broadcasting Reception Ratio Reporting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile broadcasting systems lack a defined method for reporting reception ratios, which hinders the adjustment of broadcast quality to match varying reception environments, particularly in mobile settings where terminals frequently move and reception conditions change.
Innovation Solution
A method and apparatus for reporting a reception ratio of a broadcast service, where a terminal receives a reception ratio report indication message and sends a reception ratio report message including the measured ratio of expected versus received packets, allowing the broadcasting system to adjust quality accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the broadcasting system provides broadcast services to mobile terminals without reception ratio monitoring, then the system complexity is reduced, but the broadcast service quality cannot be adjusted to match varying reception conditions
Solution Approach 1:
The patent implements a feedback mechanism where terminals measure reception ratios (based on expected versus received packets) and report them to the broadcasting system. The system uses this feedback to dynamically adjust broadcast service quality, resolving the contradiction by enabling quality adaptation through structured feedback loops without requiring complete system redesign.
Solution Approach 2:
Terminals autonomously measure their own reception ratios by comparing expected packet counts with actually received packets, and self-report these measurements to the broadcasting system. This self-service approach distributes the measurement functionality to terminals, reducing the complexity burden on the central broadcasting system while maintaining reliable quality monitoring.
2Measurement precision
If the system implements reception ratio reporting to monitor packet delivery, then the broadcast service quality can be improved, but the measurement and reporting mechanisms add system complexity
Solution Approach 1:
Terminals perform self-measurement of reception ratios using locally available information (expected packet counts from service guides and actually received packet counts), eliminating the need for complex centralized measurement infrastructure. The measurement logic is distributed to terminals, achieving precise reception monitoring without proportionally increasing overall system complexity.
Solution Approach 2:
The patent establishes a feedback channel where terminals report measured reception ratios to the broadcasting system. This feedback mechanism enables precise measurement of service delivery quality while using standardized reporting formats that minimize the complexity overhead of the measurement infrastructure.
3Adaptability or versatility
If the broadcasting system adapts to mobile environments with frequent movement, then service quality can be maintained, but the system requires complex monitoring and adjustment mechanisms
Solution Approach 1:
The patent implements dynamic adaptation by enabling the broadcasting system to adjust service delivery parameters based on real-time reception ratio measurements from mobile terminals. The system transitions from static broadcast delivery to dynamic quality adaptation, allowing service parameters to change in response to terminal movement and varying reception conditions without requiring overly complex monitoring infrastructure.

AI summary
A system for reporting a reception ratio of a broadcast service in a broadcasting system. A network entity sends a reception ratio report indication message indicating at least one measurement type of a reception ratio for a broadcast streaming service. A terminal receives the reception ratio report indication message, and sends a reception ratio report message including the reception ratio indicative of a ratio of an expectedTotalPackets indicating a total number of packets that the terminal expects to receive for a reception ratio measurement interval according to a measurement type indicated by the reception ratio report indication message, to a receivedTotalPackets indicating a total number of packets that the terminal has received for the reception ratio measurement interval.
