Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for establishing peer-to-peer (P2P) connections in wireless networks require significant user involvement and configuration, which can be frustrating and discourage users, especially novice users, due to complexity and interoperability issues.
Innovation Solution
The implementation of automatic discovery and negotiation of P2P networks and services through a P2P discovery exchange over P2P-supported protocols within a WLAN environment, allowing wireless terminals to determine compatible connections and services without manual configuration, using a control point to facilitate the exchange of P2P capabilities and configuration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration methods are used to establish P2P connections, then connection security and reliability are improved, but user involvement and configuration complexity increase significantly
Solution Approach 1:
The system performs automatic discovery and negotiation of P2P connections without requiring user intervention. The wireless terminals autonomously exchange capability information, negotiate parameters, and establish connections through automated protocols, eliminating the need for manual configuration while maintaining secure connections through encrypted capability exchange.
Solution Approach 2:
The patent introduces an optional intermediary component that facilitates P2P connection establishment by mediating the discovery and negotiation process between wireless terminals. This intermediary helps coordinate the automated exchange of capability information and negotiation parameters, ensuring reliable connection establishment while maintaining automation.
2Ease of operation
If automated discovery and negotiation is implemented, then ease of operation and user experience are improved, but device complexity and protocol overhead increase
Solution Approach 1:
The patent employs universal P2P capability information structures and standardized negotiation protocols that can be applied across different wireless terminal types and services. The capability information format and negotiation mechanism are designed to be service-agnostic, allowing the same automated discovery and negotiation framework to support multiple P2P services without increasing protocol complexity.
Solution Approach 2:
The system dynamically adjusts negotiation parameters and capability information exchange based on the specific service requirements and terminal capabilities. By parameterizing the discovery and negotiation process, the system maintains a standardized framework while adapting to different service types and device capabilities, avoiding the need for complex service-specific protocols.
3Productivity
If P2P connections are established automatically, then productivity and connection speed are improved, but bandwidth usage for capability exchange increases
Solution Approach 1:
The patent performs capability information exchange and negotiation as preliminary actions during the initial connection phase. By completing the discovery and parameter negotiation before actual data transfer begins, the system enables immediate high-speed P2P communication without repeated negotiation overhead, improving overall productivity while confining bandwidth consumption to the initial setup phase.
