Distributed Cell Status Reporting via Bearer Delay Algorithms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized reporting of cell status in wireless communications leads to significant data traffic jitter due to policy control by the PCRF, affecting user experience and resource management in wireless networks.
Innovation Solution
Implementing a method where cell status is reported using a preset delay distribution algorithm and periodic timers to distribute reporting across bearers, ensuring that cell status information is carried in uplink data packets only when necessary, thereby controlling the distribution of bearers and reducing centralized policy adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cell status is reported in a centralized manner on bearers, then cell status information can be collected efficiently, but data traffic borne on the cell experiences fierce jitter due to centralized policy control by PCRF
Solution Approach 1:
The patent segments the centralized cell status reporting function into distributed reporting across multiple bearers. Each bearer independently reports cell status information according to local conditions, dividing the monolithic centralized reporting process into smaller autonomous units that operate in parallel, thereby reducing the集中性 (centralization) that causes traffic jitter.
Solution Approach 2:
The patent implements periodic cell status reporting where bearers report status information at predetermined intervals rather than continuously or simultaneously. This periodic action smooths out the timing of status reports and associated policy control triggers, preventing sudden centralized policy adjustments that would cause fierce traffic jitter while maintaining adequate monitoring coverage.
2Adaptability or versatility
If centralized policy control is performed by PCRF on all bearers reporting cell status, then comprehensive policy decisions can be made, but service traffic experiences significant jitter
Solution Approach 1:
The patent applies local quality by allowing different bearers to have different reporting characteristics and policy control applications based on their specific service requirements. Instead of uniform centralized control, each bearer can be treated with appropriate policy control intensity and timing matched to its local service quality requirements, reducing unnecessary jitter for time-sensitive services while maintaining comprehensive policy oversight where needed.

AI summary
Determining a distribution delay of a bearer by using a preset delay distribution algorithm according to a preset time period for reporting a cell status; starting a periodic timer of the bearer after the distribution delay elapses, where the periodic timer uses the time period as a period; determining, according to the periodic timer, whether the cell status needs to be reported; and carrying information of the cell status in an uplink data packet of the bearer if the cell status needs to be reported. Thereby avoiding greatly centralized reporting of the cell status and centralized policy adjustment that is performed for the bearers, so that great jitter of service traffic borne on a cell is controlled effectively.
