Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication techniques face challenges during the handover process, particularly when a communication terminal searches for a new access point, leading to potential communication disruptions, reduced throughput, and data packet loss.
Innovation Solution
A communication system and method that utilize a smartphone and digital camera to manage handovers by analyzing the wireless LAN environment, determining the need for a handover, selecting a suitable new access point, and transmitting necessary communication settings via Bluetooth Low Energy, allowing seamless wireless communication maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication terminal performs search process for a different frequency to find handover destination AP, then it can discover new access points, but it cannot communicate with the currently connected AP causing throughput reduction and data packet loss
Solution Approach 1:
The patent applies preliminary action by having the terminal obtain communication settings (including frequency information) of the handover destination AP before actually performing the handover. The terminal receives notification from the smartphone about the destination AP's frequency and settings in advance, so when the terminal switches frequencies to search for new APs, it already has the target frequency information ready, eliminating the need to interrupt current communication for frequency scanning.
2Adaptability or versatility
If the communication terminal switches frequency to search for new AP, then it can maintain adaptability to movement, but communication disconnection occurs during the search process
Solution Approach 1:
The terminal performs preliminary actions by obtaining the destination AP's frequency and communication settings before switching. The smartphone notifies the terminal of the destination AP information in advance, allowing the terminal to prepare the frequency switch without interrupting current communication, thus maintaining connection stability while enabling AP switching.
Solution Approach 2:
The smartphone acts as an intermediary between the network and the terminal during handover. It provides the terminal with notification information about the destination AP, including frequency and communication settings, mediating the handover process so the terminal doesn't need to independently scan frequencies, thereby maintaining communication reliability during the transition.
3Adaptability or versatility
If the terminal continuously searches for AP while moving, then it can maintain connection availability, but the search process interrupts ongoing communication
Solution Approach 1:
The terminal performs preliminary action by receiving destination AP information from the smartphone before handover is needed. This eliminates the need for continuous frequency scanning during movement, as the terminal already has the target frequency and can switch directly when needed, reducing communication interruption time while maintaining connection availability.

AI summary
To more appropriately maintain a wireless communication connection, a communication apparatus (2) obtains (15,340) an identifier of a first network connected, by a first wireless communication scheme, to another communication apparatus (1); searches (110,370) for a second network by the first wireless communication scheme, which exists on the periphery, and obtains an identifier of the second network; and transmits (15,320), if the identifier of the first network and the identifier of the second network are different, a predetermined notification signal to the other communication apparatus via communication by a second wireless communication scheme with lower transmission power than the first wireless communication scheme.
