Dynamic Control Channel Timer Adjustment for Wireless Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face challenges in efficiently managing control channel timers due to limited RF spectrum, leading to resource wastage and delayed re-allocation of traffic channels, as they continue to monitor control channels even after traffic channels are released.
Innovation Solution
Adjusting the control channel timer based on the level of control communication traffic to optimize resource usage, allowing devices to stop monitoring control channels when traffic channel re-allocation is likely, thereby conserving resources and reducing latency in re-acquiring traffic channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless devices continue to monitor control channels after traffic channel release, then traffic channel re-allocation occurs faster, but device battery consumption increases and resources are wasted
Solution Approach 1:
The patent implements dynamic adjustment of the control channel monitoring timer based on network conditions. When traffic channels are frequently released and re-allocated, the timer is extended to keep devices monitoring the control channel longer, enabling faster re-allocation. When traffic channels are stable, the timer is reduced to conserve battery. This dynamic timing mechanism resolves the contradiction by adapting monitoring duration to actual network needs rather than using a fixed approach.
Solution Approach 2:
The patent changes the parameter of control channel monitoring duration based on traffic channel release patterns. By adjusting the control channel timer parameter dynamically - extending it when re-allocation is needed and reducing it when stability prevails - the system optimizes both re-allocation speed and battery consumption. This parameter adjustment directly addresses the technical contradiction by making monitoring duration conditional rather than constant.
2Use of energy by moving object
If wireless devices reduce control channel monitoring duration to conserve battery, then resource consumption decreases, but traffic channel re-allocation is delayed
Solution Approach 1:
The system dynamically adjusts the control channel monitoring timer based on observed traffic patterns and release frequencies. When the network exhibits high traffic channel turnover, the timer is automatically extended to prevent re-allocation delays. When traffic patterns are stable, the timer is reduced to conserve battery. This dynamic adaptation resolves the contradiction by ensuring monitoring duration matches actual re-allocation needs.
Solution Approach 2:
The patent employs feedback mechanisms where the device monitors traffic channel release patterns and uses this information to adjust control channel monitoring duration. The system continuously observes network behavior, processes this feedback, and modifies the monitoring timer accordingly - extending it when re-allocation activity is detected and reducing it during stable periods. This feedback loop ensures optimal balance between battery conservation and re-allocation speed.
3Reliability
If wireless devices monitor control channels for extended periods, then re-allocation responsiveness improves, but unnecessary resource consumption increases during stable traffic conditions
Solution Approach 1:
The patent implements parameter changes by adjusting the control channel monitoring timer based on traffic channel stability. During stable traffic conditions with low release frequency, the timer is reduced to eliminate unnecessary resource consumption. When volatility increases and re-allocation becomes more frequent, the timer is extended to maintain responsiveness. This parameter adaptation directly addresses the contradiction by making monitoring duration responsive to actual network conditions.
Solution Approach 2:
The system transitions from static to dynamic control channel monitoring by continuously adapting the timer duration to network conditions. The monitoring period becomes a dynamic parameter that responds to traffic channel release patterns rather than remaining fixed. This dynamic approach ensures high responsiveness during volatile conditions while conserving resources during stable periods, resolving the contradiction between reliability and energy loss.
