Terminal Device Data Duplication Control via Unified Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-connectivity scenarios, different network devices may indicate different states for the data duplication and transmission function of a radio bearer, leading to inconsistent configurations, which necessitates a method to control and synchronize these states across multiple network devices.
Innovation Solution
A terminal device acquires transmission control information from each network device, updates a control variable to maintain consistent states for the data duplication and transmission function, and controls the function accordingly using a mapping relation table to determine the target state, ensuring that the data duplication and transmission function is activated or deactivated uniformly across all network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple network devices independently control the data duplication function state for the same bearer, then each network device can optimize transmission according to its local conditions, but the terminal device receives inconsistent state indications leading to configuration conflicts
Solution Approach 1:
The patent merges multiple independent control indications from different network devices into a unified control mechanism. The terminal device collects transmission control information from multiple network devices and processes them together through a unified control variable and mapping relation table to determine the final state, transforming multiple independent control streams into a single coordinated control outcome.
Solution Approach 2:
The patent introduces a mapping relation table as an intermediary mechanism between network device indications and the final control state. This mapping relation table acts as a mediator that reconciles potentially conflicting indications from different network devices and translates them into a consistent control decision, preventing direct conflicts while preserving local optimization capabilities.
2Manufacturing precision
If the terminal device follows indications from each network device separately, then each indication can be executed precisely, but the final state may conflict with other network device indications
Solution Approach 1:
The patent performs preliminary processing of transmission control information from multiple network devices before final state determination. The terminal device collects and processes all indications in advance, updates control variables based on the mapping relation table beforehand, and only then determines the final state, ensuring that precision in executing individual indications does not compromise overall configuration stability.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal device continuously monitors transmission control information from multiple network devices, compares it with the current control variable state, and adjusts the final state determination accordingly. This feedback loop ensures that precision in indication execution is maintained while preventing configuration state conflicts through continuous reconciliation.
