Adaptive P2P Communication Mode Selection in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is no effective method for adaptively selecting between Peer-to-Peer (P2P) and wireless communication modes among Mobile Stations (MSs) to optimize resource utilization, especially considering the wireless environment and distance between MSs.
Innovation Solution
A method and apparatus where a Base Station (BS) broadcasts an instruction message to neighbor MSs to gather P2P-related information, determining whether P2P communication is possible and selecting the appropriate communication mode based on this information, and transmitting a connection response message to establish the connection in the desired mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If P2P communication is used between MSs, then resource utilization is improved and service quality is enhanced, but the ability to adapt to varying wireless environments and distances is insufficient
Solution Approach 1:
The patent implements dynamic communication mode selection where the BS determines whether to establish P2P or BS-assisted connections based on real-time wireless environment conditions, MS locations, and distance measurements. This dynamic adaptation allows the system to switch between communication modes optimally, resolving the contradiction between resource utilization efficiency and adaptability to varying wireless environments.
Solution Approach 2:
The patent employs feedback mechanisms where the BS receives location information and wireless environment data from MSs, processes this information to determine the optimal communication mode, and provides connection establishment decisions back to the MSs. This feedback loop enables adaptive selection between P2P and BS-assisted modes based on current system state, addressing the adaptability deficiency.
2Reliability
If BS-assisted connection is used, then reliability is improved for long-distance communication, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent applies local quality by making communication mode decisions specific to each MS pair's local conditions (distance, wireless environment, location). Instead of a uniform BS-assisted approach for all connections, the system evaluates local conditions and selects P2P mode when appropriate, thereby improving resource utilization while maintaining reliability where needed.
Solution Approach 2:
The patent changes the communication mode parameter (P2P vs. BS-assisted) based on varying system parameters such as MS distance, wireless environment quality, and location information. This parameter-based selection allows the system to optimize the balance between connection reliability and resource utilization efficiency by adapting to different operational conditions.
3Device complexity
If P2P communication mode is selected without considering wireless environment, then device complexity is reduced, but measurement precision of communication feasibility deteriorates
Solution Approach 1:
The patent introduces the BS as an intermediary that performs the complex task of evaluating wireless environment conditions, MS locations, and communication feasibility. Instead of requiring MSs to independently assess complex environmental factors, the BS acts as a mediator that gathers necessary information and makes the determination, thereby maintaining low device complexity while achieving high measurement precision through centralized environmental assessment.

AI summary
A method for operating a Base Station (BS) in a wireless communication system capable of supporting a Peer-to-Peer (P2P) communication is provided. The method includes receiving at least one response message from at least one Mobile Station (MS) that has received a request message from a first MS and determining whether to allow the first MS to performs the P2P communication with a second MS based on the at least one response message.
