Wireless Device Reverse Link Unreliability Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently managing unreliable reverse link channels, leading to inefficient access attempts and power consumption issues due to the inability to distinguish between temporary and persistent unreliability.
Innovation Solution
A method and apparatus that determine the level of unreliability of a reverse link channel, allowing devices to avoid systems with persistent unreliability for longer periods while attempting access to more reliable systems, using timers and reselection procedures to balance access attempts and conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices continuously attempt access to avoided wireless communication systems after a specified time, then connection reliability may improve, but power consumption increases
Solution Approach 1:
The patent implements dynamic timer values that adjust based on the type of unreliability detected. Temporary unreliability uses a first timer value allowing more frequent access attempts, while persistent unreliability uses a second, longer timer value reducing access attempts. This dynamic adjustment optimizes the balance between connection reliability and power consumption by adapting the avoidance duration to the actual system conditions.
2Use of energy by moving object
If devices avoid systems with temporary unreliability for long periods, then power consumption decreases, but connection reliability worsens
Solution Approach 1:
The system dynamically adjusts avoidance timer values based on unreliability classification. For temporary unreliability, a shorter first timer value is used, allowing quicker reconnection attempts and maintaining better connection reliability. For persistent unreliability, a longer second timer value is used to reduce power consumption by avoiding futile access attempts. This dynamic differentiation resolves the contradiction by matching timer duration to the actual system state.
3Productivity
If devices distinguish between temporary and persistent unreliability, then access optimization improves, but system complexity increases
Solution Approach 1:
The patent segments unreliability into two distinct categories: temporary and persistent. Each category is associated with a different timer value (first timer value for temporary, second timer value for persistent). This segmentation allows the system to apply different access strategies based on the type of unreliability, optimizing access efficiency while keeping the complexity manageable through clear classification and corresponding timer differentiation.

AI summary
Methods and apparatuses are provided that facilitate avoiding one or more wireless communication systems based at least in part on determining a level of unreliability of a reverse link channel related to a system. This can be based at least in part on determining whether the system can be accessed over the reverse link channel. If not, the wireless communication system can be avoided to conserve power utilized to perform such access attempts. Where the unreliability is temporary, however, some access attempts can be performed for systems of higher priority than a current system during the period of avoidance of one or more higher priority systems.
