Dynamic Communication Path Selection for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for selecting communication paths between user equipment (UEs) with ProSe capability do not effectively consider dynamic situations, often relying on static policies that fail to optimize communication paths based on real-time link quality and availability.
Innovation Solution
A wireless communication method and system that allows a UE to select between direct PCS and Uu communication paths based on path status, including link existence and quality, using a path selection policy to determine the best path for service communication, and initiating link or session modifications as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static path selection policies are used, then device complexity is reduced, but communication efficiency and reliability deteriorate due to inability to adapt to dynamic link conditions
Solution Approach 1:
The patent implements dynamic path selection by enabling UEs to monitor link status in real-time and switch between PCS and Uu communication paths based on current conditions. The system transitions from static pre-configured policies to dynamic adaptation where the communication path is selected based on real-time link availability and quality, resolving the contradiction between simplicity and efficiency.
Solution Approach 2:
The patent employs feedback mechanisms where UEs continuously monitor the status of both PCS and Uu links, and use this feedback information to make informed path selection decisions. The system collects feedback on link availability and quality, then adjusts path selection accordingly, improving communication efficiency while maintaining manageable complexity through structured feedback processing.
2Speed
If direct PCS communication path is used, then communication speed is improved, but reliability deteriorates when link availability is poor
Solution Approach 1:
The patent changes the selection parameter from fixed static policies to dynamic parameters including link availability status and link quality metrics. By monitoring these parameters in real-time and switching between PCS (for speed when available) and Uu paths (for reliability when PCS is poor), the system optimizes both speed and reliability based on current conditions.
Solution Approach 2:
The patent introduces an intermediary path selection mechanism that evaluates both PCS and Uu paths and selects the appropriate one based on current conditions. This intermediary layer mediates between the two communication paths, allowing the system to leverage the speed advantage of PCS when available while falling back to the reliability of Uu path when needed.
3Reliability
If Uu communication path via network is used, then communication reliability is improved, but communication efficiency deteriorates due to network routing overhead
Solution Approach 1:
The patent makes the communication path dynamic rather than fixed, allowing the system to switch from Uu path (when reliability is needed and PCS unavailable) to PCS path (when efficiency is prioritized and PCS is available). This dynamic adaptation resolves the contradiction by selecting the optimal path based on real-time conditions rather than always using the more reliable but less efficient Uu path.
