Wireless Data Exchange Control for Portable Game Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face inefficiencies in data communication as they often repeat communication with partners with which communication has already been established, leading to unnecessary data exchange.
Innovation Solution
The system includes identification information receiving and registration units that determine whether to execute data communication based on received identification information, registering partners with which communication has been done, and controlling data communication processes to avoid repetitive exchanges with already registered partners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication is automatically executed when information processing apparatuses come close to each other, then data exchange can occur without user intervention, but communication is repeated with partners already communicated with
Solution Approach 1:
The system performs preliminary registration of communication partners' identification information in a storage unit after each communication session. Before executing automatic communication, the system checks whether the partner's identification information is already registered, thereby preventing repetitive communication with the same partner and improving communication efficiency while maintaining ease of operation
2Adaptability or versatility
If communication is executed with unspecified partners within communicable range, then communication flexibility is improved, but unnecessary repetitive communication occurs
Solution Approach 1:
The system implements a feedback mechanism where the result of each communication session (partner identification information) is fed back to the storage unit for registration. Before subsequent communication attempts, the system queries this stored information to determine whether communication should be executed, thereby eliminating unnecessary repetitive communication while preserving flexibility to communicate with new partners

AI summary
An exchange data communication determining unit determines, based on a received reception wireless frame, whether or not a communication partner is an exchange partner with which the exchange data can be exchanged. Receiving a notice that exchange of the exchange data is possible, a data communication control unit executes a process for giving/receiving the exchange data. A machine identification information registration unit stores an MAC address of a portable game machine in an MAC address list saving area. Again, the wireless frame transmitting/receiving unit sets a transmission wireless frame and executes an exchange partner searching process. An exchange data communication determining unit determines whether or not an MAC address included in the received reception wireless frame is registered with the MAC address list saving area, and if it is registered, the data communication is terminated.
