Communication Mode Selection for Mobile Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems require time-consuming and inconvenient manual processes for selecting and agreeing on communication modes between Mobile Stations (MSs), often preventing P2P communication even when it is preferable due to lack of resources or unmet agreements.
Innovation Solution
A method and system that automatically determine the optimal communication mode between MSs by estimating expected performance in both cellular and P2P modes and selecting the best mode based on comparisons, eliminating the need for mutual agreement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual communication mode selection and mutual agreement processes are implemented between MSs, then communication mode can be determined, but the process becomes time-consuming and inconvenient
Solution Approach 1:
The system enables MSs to automatically determine their own communication mode by evaluating preset criteria (distance, resource availability, performance estimates) without requiring manual user input or lengthy negotiation protocols between devices
Solution Approach 2:
The system performs preliminary assessments of communication conditions (distance calculation, resource availability checks, performance estimation) before actual communication begins, allowing mode determination to be made in advance and eliminating time-consuming on-the-spot decisions
2Reliability
If mutual agreement on P2P communication mode is required between MSs, then communication can be established, but the process becomes inconvenient and complex
Solution Approach 1:
Each MS independently evaluates whether P2P mode is suitable by checking preset conditions (distance within threshold, available resources, estimated performance) and automatically selects the mode without requiring back-and-forth agreement protocols between the communicating devices
Solution Approach 2:
The system changes the operational parameters (communication mode) based on evaluated conditions such as distance, resource availability, and performance estimates, automatically adjusting between cellular and P2P modes according to the current situation
3Productivity
If P2P communication mode is used when resources are unavailable or agreement is not reached, then communication can proceed, but system reliability decreases
Solution Approach 1:
The system performs preliminary checks of resource availability and communication conditions before selecting P2P mode, estimating expected performance metrics in advance to ensure that mode selection will not compromise communication quality
Solution Approach 2:
The system uses feedback from performance estimation and condition evaluation to guide mode selection, ensuring that P2P mode is only chosen when preliminary assessments indicate sufficient resources and acceptable performance expectations

AI summary
A method and system for determining a communication mode in a communication system are provided. The system and method include determining whether a first MS and a second MS are located within a preset area where P2P communications are available, estimating a first expected performance that can be achieved when the first and second MSs operate in a cellular communication mode, estimating a second expected performance that can be achieved when the first and second MSs operate in a P2P communication mode if the first and second MSs are located within the predetermined area, and selecting one of the cellular communication mode and the P2P communication mode as a communication mode between the first and second MSs by comparing the first expected performance with the second expected performance.
