Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional Radio Access Network (RAN) is inadequate in considering new Quality of Service (QoS) related parameters such as survival time and burst spread, leading to inefficiencies in data transmission prioritization and reliability.
Innovation Solution
A method and apparatus that prioritize data transmissions from a terminal device to a network device based on specific conditions, entering and exiting a prioritized transmission phase using defined rules to ensure successful data transmission within the survival time, thereby enhancing RAN reliability and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional RAN transmission methods are used, then device complexity is low, but reliability of data transmission deteriorates due to lack of consideration for new QoS parameters
Solution Approach 1:
The patent implements dynamic transmission phase management by transitioning between normal phase and prioritized phase based on real-time condition evaluation. The system dynamically adjusts transmission priorities using priority rules that are activated only when specific conditions (e.g., survival time thresholds, burst spread limits) are met, rather than maintaining static high-priority transmission continuously. This dynamic approach improves reliability during critical conditions while avoiding unnecessary complexity during normal operation.
Solution Approach 2:
The patent changes transmission priority parameters based on evaluated conditions. When conditions indicate risk (such as approaching survival time limits or excessive burst spread), the system changes the priority parameter from normal to high, triggering prioritized transmission. This parameter change mechanism allows the system to adapt transmission behavior to QoS requirements without permanently increasing complexity, as the high-priority state is conditional and reversible.
2Reliability
If prioritized transmission phase is continuously maintained, then data transmission reliability is improved, but loss of time increases due to unnecessary prioritization during normal conditions
Solution Approach 1:
The patent employs periodic evaluation of transmission conditions rather than continuous prioritized transmission. The system periodically checks whether conditions warrant entry into prioritized phase (e.g., monitoring survival time, burst spread, and other QoS parameters). This periodic action ensures that prioritization is applied only when necessary, avoiding time loss from continuous high-priority transmission during normal conditions while maintaining reliability when conditions deteriorate.
Solution Approach 2:
The patent uses preliminary condition evaluation to determine when prioritized transmission should be activated. By assessing QoS parameters and conditions before entering prioritized phase, the system prepares for potential reliability issues in advance rather than reacting after problems occur. This preliminary action allows the system to enter prioritized mode proactively when conditions indicate risk, improving reliability without maintaining unnecessary prioritization during normal operation.
3Reliability
If new QoS parameters are considered, then data transmission reliability is improved, but device complexity increases due to additional parameter management
Solution Approach 1:
The patent segments QoS parameter management into distinct evaluation components. Instead of managing all QoS parameters uniformly, the system divides them into specific evaluable conditions (such as survival time, burst spread, and other discrete parameters). Each parameter is evaluated independently against predefined thresholds, and priority rules are triggered based on individual parameter violations. This segmentation reduces complexity by breaking down complex QoS management into manageable, independent evaluation units.
Solution Approach 2:
The patent introduces priority rules as intermediary mechanisms between QoS parameters and transmission behavior. Rather than directly managing complex QoS parameters, the system uses priority rules as intermediaries that translate parameter conditions into actionable transmission decisions. These priority rules act as mediators that simplify the management complexity by providing a standardized interface between QoS parameter evaluation and transmission priority adjustment, reducing the burden of direct parameter management.
