Wireless Relay Device Load Reduction via Terminal ID Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless data communication systems face resource shortages when multiple mobile terminals request connections to a relay device, leading to processing load issues and disruptions in data communication.
Innovation Solution
The system employs an identification information storage unit, signal receiver, determiner, connection requester, and data communicator to manage terminal identification information, allowing the server to broadcast identification information and enabling mobile terminals to request connections only when matching information is received, thereby reducing the relay device's processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mobile terminals simultaneously request wireless connection to the relay device, then the availability of wireless communication is improved, but the processing load of the relay device increases and resource shortages occur
Solution Approach 1:
The server device performs preliminary action by broadcasting terminal identification information before actual data communication begins. Mobile terminals check this broadcast information and only request wireless connections if their identification information is included, preventing unnecessary connection requests and reducing the relay device's processing load while maintaining communication availability for authorized terminals.
2Area of stationary object
If the relay device manages more terminal identification information, then the coverage area is expanded, but the resource consumption of the relay device increases
Solution Approach 1:
The patent extracts terminal identification information from the relay device and places it in the server device. The server device broadcasts this information to mobile terminals, which then use it to determine whether to request wireless connections. This extraction reduces the relay device's resource consumption while maintaining expanded coverage area through server-based management.
3Loss of time
If mobile terminals continuously monitor for connection opportunities, then the response time is reduced, but the energy consumption of mobile terminals increases
Solution Approach 1:
The server device periodically broadcasts terminal identification information to mobile terminals. Terminals listen for these periodic broadcasts and only expend energy when new information is transmitted, rather than continuously monitoring. This periodic action maintains fast response time while significantly reducing energy consumption compared to continuous monitoring.

AI summary
An example mobile terminal is a terminal for transmitting and receiving data to and from a server device via an access point by wireless communication. The mobile terminal includes an identification information storage unit configured to store a terminal ID, a signal receiver configured to receive a broadcast signal containing a plurality of terminal IDs transmitted from the server device via the access point, an ID determiner configured to determine whether or not any of the terminal IDs contained in the received signal corresponds to the terminal ID of this mobile terminal, a connection requester configured to, when the ID determiner determines that one of the terminal IDs corresponds to the terminal ID of this mobile terminal, request a wireless connection to the access point, and a data communicator configured to transmit or receive data to or from the server device via the access point by wireless communication.
