Adaptive Connection Timer for Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, determining the optimal value for a timer used to detect connection problems is challenging due to the complexity of channel states, leading to either premature detection of issues or failure to detect problems in a timely manner.
Innovation Solution
A method in a first node for wireless communications, where the value of a first timer depends on a condition based on location and time information, allowing for adaptive configuration of the timer value to better align with channel state changes and node capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed network configuration value is used for the timer, then device complexity is reduced, but adaptability to channel state changes deteriorates
Solution Approach 1:
The patent implements dynamic timer values that adapt to changing channel conditions. The terminal device determines timer values based on real-time channel state information, making the timer flexible rather than fixed. This allows the system to respond to varying radio conditions while maintaining manageable complexity through standardized adaptation mechanisms.
Solution Approach 2:
The patent changes the timer parameter based on channel state conditions. Different timer values are selected according to the quality of the radio channel, allowing optimal detection timing under different conditions. This parameter adaptation resolves the contradiction by making the timer value variable rather than fixed, improving adaptability without significantly increasing device complexity.
2Loss of time
If a small timer value is configured, then connection problems are detected earlier, but false detection increases causing communication interruption
Solution Approach 1:
The patent adjusts the timer value parameter dynamically based on channel state. When channel conditions are good, smaller timer values can be used for faster detection. When conditions are poor or uncertain, larger timer values prevent false detections. This conditional parameter adjustment resolves the contradiction between early detection and false alarm reduction.
Solution Approach 2:
The patent makes the timer value dynamic rather than static, allowing it to change based on real-time channel assessments. This dynamic adjustment enables the system to optimize detection timing according to actual conditions, reducing both detection delay and false positives by adapting the timer to current channel quality.
3Reliability
If a large timer value is configured, then false detection is reduced, but connection problems are not detected in a timely manner
Solution Approach 1:
The patent implements parameter changes based on channel state assessment. Instead of using a consistently large timer value, the system selects appropriate timer values according to channel conditions. This allows timely detection when conditions warrant it while maintaining reliability when conditions are uncertain, resolving the contradiction between speed and accuracy.
4Measurement precision
If adaptive timer values are implemented, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The patent implements parameter changes based on channel state information that is already available in the system. By leveraging existing measurements and assessments, the timer value adaptation adds precision without requiring entirely new measurement mechanisms, thus limiting the increase in device complexity to logical processing of existing data.

AI summary
Receiving a first signaling, the first signaling configuring a first timer; an expiration of the first timer determining that there is a connection problem; starting the first timer, a value of the first timer depending on a first condition; when the first condition is met, a value of the first timer being a first value; when the first condition is not met, a value of the first timer being a second value; herein, the meaning of the phrase that an expiration of the first timer determines that there is a connection problem is: an expiration of the first timer triggers entering RRC_IDLE state, or an expiration of the first timer triggers an RRC connection re-establishment, or RRC reports connection failure to higher layers. The present application enables a more appropriate determination of whether there is a problem with the connection.
