Solution Overview
Problem
Existing methods for connecting communication apparatuses to access points lack convenience, particularly in seamlessly transitioning between different communication protocols and ensuring secure, efficient network setup.
Innovation Solution
A communication apparatus that includes a control unit to manage protocol transitions and a transmission unit for sending protocol-related information, enabling it to connect to an access point using acquired connection information, thereby facilitating convenient and secure network setup between communication apparatuses and access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication apparatus uses a single protocol for all communications, then the system is simple and easy to implement, but it cannot seamlessly transition between different communication protocols (e.g., from setup protocol to data transmission protocol)
Solution Approach 1:
The communication apparatus dynamically switches between different communication protocols based on the operational state. The control unit activates a first protocol during the setup phase and transitions to a second protocol for data transmission, making the protocol selection adaptive rather than static. This resolves the contradiction by enabling protocol versatility while managing complexity through automated, state-based protocol selection.
2Ease of operation
If the communication apparatus manually configures network settings, then protocol transitions can be controlled, but the network setup process becomes time-consuming and inconvenient
Solution Approach 1:
The communication apparatus performs self-configuration by automatically receiving connection information from the information processing apparatus and configuring its own network settings without user intervention. The control unit autonomously manages the transition from setup protocol to data transmission protocol and establishes the wireless connection to the access point, thereby improving ease of operation while minimizing setup time.
3Reliability
If connection information is transmitted securely using encryption, then network security is improved, but the communication overhead and processing time increase
Solution Approach 1:
Connection information is pre-encrypted and prepared in advance during the setup phase using the first protocol. The information processing apparatus generates and transmits encrypted connection information to the communication apparatus before actual data transmission begins. This preliminary encryption action ensures security while allowing faster data transmission during the operational phase, as the encryption/decryption overhead is concentrated in the initial setup rather than continuous transmission.

AI summary
A communication apparatus is configured to communicate with an information processing apparatus. The communication apparatus includes a first control unit configured to, based on a start request being received from the information processing apparatus via first communication with the information processing apparatus using a first protocol, perform first control to start a first state capable of performing second communication with the information processing apparatus using a second protocol different from the first protocol.
