Quantum Encrypted Call Setup via Adaptive Packet Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently configuring quantum-encrypted calls due to the repeated transmission of packets over UDP, which increases the time required for call setup.
Innovation Solution
An electronic device determines the number of times to transmit packets for identifying session identity information and encryption keys based on the channel status between the cellular network and the device, optimizing packet transmission to reduce call configuration time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packets are transmitted multiple times over UDP to increase reception probability, then reliability of packet delivery is improved, but the time taken to configure quantum-encrypted call increases
Solution Approach 1:
The patent applies dynamics by making the packet transmission count adaptive rather than fixed. The system dynamically adjusts the number of retransmissions based on real-time channel status feedback, allowing the transmission strategy to optimize between reliability and time consumption according to current network conditions
Solution Approach 2:
The patent implements feedback mechanisms where the electronic device monitors channel status and uses this information to adjust packet transmission strategies. The feedback loop enables the system to learn from transmission outcomes and optimize retransmission counts to balance delivery reliability with configuration time
2Reliability
If the number of packet transmissions is increased to ensure packet reception, then reliability of key and identity information exchange is improved, but call setup efficiency deteriorates
Solution Approach 1:
The system dynamically adjusts transmission parameters based on channel conditions rather than using a static retransmission strategy. This allows the call setup process to adapt its information exchange reliability measures to actual network conditions, preventing unnecessary delays in good conditions while ensuring reliability when needed
Solution Approach 2:
The patent changes the parameter of transmission count based on channel status. By varying this parameter according to network conditions, the system optimizes the balance between information exchange reliability and call setup efficiency, avoiding fixed over-transmission in good conditions
