Mobile Device Abnormal Packet Detection and IP Re-derivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile electronic devices face significant power consumption issues due to receiving and processing unwanted packets when connected to networks, particularly during attacks like SYN floods, leading to unnecessary energy expenditure.
Innovation Solution
A communication method for mobile devices that identifies abnormal packets and increments a count value; when this count exceeds a threshold, the device re-derives its IP address to reduce the receipt of abnormal packets, implemented through a communication unit and processing unit that manage network connections and IP address reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile electronic device continuously receives and processes network packets, then network connectivity is maintained, but power consumption increases due to processing unwanted packets
Solution Approach 1:
The patent applies preliminary action by implementing a count value mechanism that tracks abnormal packets before triggering IP address re-derivation. The system preliminarily counts and monitors packet abnormalities, then only re-derives the IP address when the count exceeds the threshold, avoiding premature or unnecessary re-derivation operations that would waste power.
Solution Approach 2:
The patent changes the parameter of IP address when abnormal packet accumulation exceeds a threshold. By dynamically re-deriving the IP address based on the count value threshold, the system adapts to network conditions and reduces power consumption by avoiding continuous processing of unwanted packets while maintaining necessary network connectivity.
2Use of energy by moving object
If the mobile electronic device re-derives IP address frequently to avoid abnormal packets, then power consumption for processing abnormal packets is reduced, but network connectivity stability deteriorates
Solution Approach 1:
The patent implements feedback through the count value mechanism that continuously monitors abnormal packet reception. The system only re-derives the IP address when the count value exceeds a predetermined threshold, providing feedback-based control that prevents frequent or unnecessary re-derivation operations while still responding to actual abnormal packet accumulation, thus balancing power savings with connectivity stability.
Solution Approach 2:
The preliminary action of counting and monitoring abnormal packets before triggering IP re-derivation prevents premature or excessive re-derivation operations. This ensures that IP address re-derivation is performed only when necessary, maintaining network connectivity stability while reducing power consumption from unnecessary processing operations.
3Productivity
If the mobile electronic device processes all received packets, then complete network communication is achieved, but power consumption increases due to processing unwanted or abnormal packets
Solution Approach 1:
The patent extracts and identifies abnormal packets from the overall network traffic through the count value monitoring mechanism. By separating and tracking only the abnormal packets that exceed the threshold, the system can take corrective action (IP re-derivation) only when necessary, avoiding the need to process all packets continuously and thereby reducing power consumption while maintaining communication completeness.
Solution Approach 2:
The system changes the communication parameter (IP address) based on the accumulation of abnormal packets. This parameter change allows the system to filter out unwanted packets more effectively, reducing the processing load on the mobile device while maintaining the completeness of necessary network communications.

AI summary
A communication method and a mobile electronic device are provided. The communication method includes: receiving a message packet; determining whether or not the received message packet is an abnormal packet; and when the received message packet is determined out as the abnormal packet, increasing a count value; keeping to receive the message packets and determine whether or not the received message packet is an abnormal packet; and when the count value is greater than an upper-limit value, re-deriving an IP address.
