Image Processing System Handover Protocol Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing handover technique in wireless communication systems leads to increased system load due to unnecessary connections and prolonged setup times when switching from short-range to long-range communication protocols, as devices may connect before necessary data is ready for transmission.
Innovation Solution
Implementing an image processing system where long-range communication is established only when specific image transmission conditions are met, such as completion of document reading or generation of image data, rather than immediately after connection information is transmitted via short-range communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the communication protocol is changed immediately after connection information is transmitted via short-range communication, then the handover process is completed faster, but unnecessary connections are established increasing system load
Solution Approach 1:
The system performs preliminary actions by transmitting connection information via short-range communication (NFC) in advance, but delays the actual long-range communication establishment until image data is ready. This preliminary setup without immediate connection reduces unnecessary system load while maintaining fast handover capability.
Solution Approach 2:
The system dynamically adjusts the handover process based on data readiness status. Instead of a fixed immediate connection approach, the system flexibly determines when to establish long-range communication - either immediately if data is ready, or after a predetermined waiting period if data is being generated, thereby optimizing system load.
2Speed
If long-range communication is established immediately after short-range communication, then communication readiness is achieved faster, but data transmission efficiency decreases due to unnecessary connections
Solution Approach 1:
Connection information is prepared and transmitted in advance via short-range communication, but the actual long-range communication channel is only activated when image data is ready. This preliminary preparation maintains fast setup speed while avoiding premature connections that would reduce transmission efficiency.
Solution Approach 2:
The system uses short-range communication to transmit a copy of essential connection information, allowing the long-range communication parameters to be pre-configured without establishing the actual data transmission channel until necessary, thus maintaining both speed and efficiency.
3Loss of time
If the communication protocol changes from short-range to long-range immediately, then protocol handover is completed faster, but connection establishment becomes unnecessary increasing system load
Solution Approach 1:
The protocol handover process is initiated in advance by transmitting long-range communication parameters via short-range communication, but the actual protocol switching and connection establishment is delayed until image data readiness is confirmed, reducing unnecessary connection management complexity.
Solution Approach 2:
Short-range communication acts as an intermediary that transfers protocol handover information without immediately triggering long-range communication. This intermediary step allows the system to prepare for protocol changes without committing to unnecessary connections, simplifying connection management.

AI summary
Image processing systems include image processing apparatuses and information processing apparatuses. Image processing apparatuses include image processing devices, which perform image processing for printing print image data, generating scanning image data, or both; and first and second communication devices, which communicate using first and second communication protocols, respectively. Information processing apparatuses include third and fourth communication devices, which communicate using the first and second communication protocols, respectively. First and third communication devices communicate therebetween using the first communication protocol to transmit connection information. Image processing apparatuses, information processing apparatuses, or both determine whether an image transmission condition for transferring the image data between second and fourth communication devices is satisfied. Second and fourth communication devices use connection information to establish communication therebetween using the second communication protocol in response to the determining that the image transmission condition is satisfied and transmit the image data therebetween using the second communication protocol.
