Dual-Protocol Communication Apparatus for Secure Access Point Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses face challenges in improving the convenience of establishing connections with access points, particularly in efficiently switching between different communication protocols and securely transmitting connection information.
Innovation Solution
A communication apparatus is designed to switch between two communication protocols, allowing it to communicate with an information processing apparatus using one protocol while transmitting necessary information for communication using the second protocol. This apparatus includes a first control unit for initiating both communication states, a transmission unit for sending predetermined information, a communication unit for establishing a connection based on the transmitted information, and a second control unit for using the obtained connection information to establish a connection with the access point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication apparatus uses a single protocol for communication, then the device complexity is reduced, but the adaptability to different communication standards deteriorates
Solution Approach 1:
The patent introduces a protocol conversion unit that acts as an intermediary between the first protocol and second protocol. This unit receives data in the first protocol, converts it to the second protocol, and transmits it to the information processing apparatus. This mediator approach enables the communication apparatus to support multiple protocols without requiring simultaneous implementation of complex dual-protocol stacks, thus improving adaptability while controlling device complexity.
2Reliability
If connection information is transmitted directly using the second protocol, then the communication efficiency is improved, but the security of information transmission deteriorates
Solution Approach 1:
The patent implements preliminary action by first establishing a secure communication channel using the first protocol before transmitting connection information. The apparatus initially communicates with the information processing apparatus using the first protocol to securely exchange authentication data and connection credentials. Only after this secure preliminary exchange is complete does the apparatus switch to using the second protocol for actual data transmission, ensuring that sensitive connection information is never transmitted over an unsecured channel while maintaining efficient communication.
3Ease of operation
If the communication apparatus switches protocols dynamically, then the ease of operation is improved, but the reliability of communication deteriorates
Solution Approach 1:
The patent incorporates feedback mechanisms where the communication apparatus continuously monitors the status and performance of the current protocol being used. Based on feedback regarding protocol compatibility, transmission quality, and connection stability, the apparatus automatically selects and switches between the first and second protocols as needed. This feedback-driven approach enables automatic protocol switching that maintains communication reliability by selecting the most appropriate protocol based on real-time conditions rather than arbitrary switching.

AI summary
A communication apparatus configured to communicate with an information processing apparatus, the communication apparatus includes a first control unit configured to perform, in a case where a predetermined operation is performed on the communication apparatus, first control to start both a first state to communicate with the information processing apparatus using a first protocol and a second state to communicate with the information processing apparatus using a second protocol different from the first protocol, and a second control unit configured to perform, in a case where connection information for use by the communication apparatus to connect to an access point is obtained from the information processing apparatus via communication with the information processing apparatus using the second protocol based on predetermined information transmitted using the first protocol, second control to establish a connection between the communication apparatus and the access point by using the connection information.
