Communication Apparatus Protocol Switching Skip Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices experience delays in reconnecting to networks due to the need for repeated protocol setting and negotiation procedures when switching between communication protocols, such as HTTP/1.1 and HTTP/2, especially when moving out of wireless LAN areas or changing power states.
Innovation Solution
A communication apparatus with a designation unit for selecting a connection destination, a determination unit to assess whether to skip protocol switching, and a transmission unit to either skip or execute protocol switching processing based on the determination, allowing for efficient reconnection by transmitting connection requests directly using the second communication protocol if skipping is determined.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protocol switching processing is executed every time a device reconnects to the network, then communication reliability is ensured through proper protocol negotiation, but connection establishment time increases
Solution Approach 1:
The patent applies preliminary action by determining in advance whether protocol switching processing can be skipped based on stored identification information about the connection destination. The determination unit checks if the connection destination is registered before initiating connection, allowing the system to prepare and execute the appropriate path (skip or execute protocol switching) without delay during actual reconnection.
Solution Approach 2:
The patent changes the parameter of protocol negotiation by conditionally skipping it based on the determination result. When identification information matches a registered connection destination, the protocol switching processing is skipped entirely, allowing direct transmission using the second communication protocol. This dynamic parameter change optimizes connection time while maintaining reliability when needed.
2Loss of time
If protocol switching processing is skipped during reconnection, then connection establishment time is reduced, but communication reliability may be compromised without proper protocol negotiation
Solution Approach 1:
The patent implements feedback through the determination unit that continuously checks whether identification information about the connection destination is registered. This feedback mechanism ensures that protocol switching is skipped only when there is confirmed prior registration and matching identification information, thereby maintaining reliability while reducing connection time. The system feedback loop prevents premature skipping that could compromise communication quality.

AI summary
A communication apparatus includes a designation unit configured to designate a connection-destination communication apparatus, a determination unit configured to determine, based on whether identification information about the connection-destination communication apparatus designated by the designation unit is registered, whether to skip protocol switching processing for switching from a first communication protocol to a second communication protocol, and an execution unit configured to execute the protocol switching processing to switch from the first communication protocol to the second communication protocol in a case where the determination unit determines not to skip the protocol switching processing.
