Solution Overview
Problem
Existing communication systems face challenges in efficiently establishing connections between information-processing apparatuses and communication apparatuses using connection information, particularly in direct and infrastructure modes, leading to suboptimal performance in establishing and maintaining connections.
Innovation Solution
The implementation of a communication system that utilizes both Wi-Fi and Bluetooth Low Energy (BLE) communication methods to facilitate connection setting processes, allowing for direct peer-to-peer connections and infrastructure connections by activating specific modes and functions within the communication apparatus, such as Wi-Fi Direct and software access points, to manage and transmit connection information effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If connection information is transmitted using existing communication methods, then connection establishment is possible, but connection establishment efficiency and reliability are insufficient
Solution Approach 1:
The communication apparatus transmits connection information to the information-processing apparatus in advance before actual connection is needed. This preliminary transmission of connection information (including access point details, authentication credentials, and network parameters) enables the information-processing apparatus to be pre-configured, significantly accelerating subsequent connection establishment and improving both efficiency and reliability.
Solution Approach 2:
The patent introduces a dedicated connection information transmission mechanism that acts as an intermediary between the communication apparatus and information-processing apparatus. This intermediary channel specifically handles connection setup data, separating it from regular data transmission and ensuring reliable delivery of critical connection parameters, thereby improving overall connection establishment reliability.
2Adaptability or versatility
If multiple communication modes (direct and infrastructure) are supported, then versatility is improved, but system complexity increases
Solution Approach 1:
The communication apparatus is designed with multi-functional capability to support both direct connection mode and infrastructure connection mode. By integrating multiple communication modes into a single unified system, the apparatus can adapt to different network environments and connection requirements without requiring separate dedicated systems, thus improving versatility while managing complexity through integration.
Solution Approach 2:
The system dynamically switches between direct connection mode and infrastructure connection mode based on available resources, network conditions, and connection requirements. This dynamic adaptability allows the system to optimize performance for each specific scenario while maintaining a unified underlying architecture, thereby achieving versatility without proportionally increasing complexity.
