Dynamic Packet Priority Management for Mobile Network Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems fail to guarantee communication quality when terminals move, leading to deteriorated network resource allocation and communication quality due to unreserved network paths.
Innovation Solution
A communication system with a priority-assigning unit and link-managing units that update packet priorities based on changing link conditions, ensuring continuous communication quality by managing and reassigning priorities when terminals move.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network resources are reserved using RSVP before communications begin, then communication quality is guaranteed, but the system cannot adapt when terminals move and communication paths change
Solution Approach 1:
The patent applies dynamics by making the priority assignment adaptive to changing network conditions. Instead of static RSVP reservations, the system dynamically reassigns priorities when terminals move or paths change, allowing the network to adapt while maintaining quality of service through continuous priority management rather than fixed reservations
Solution Approach 2:
The patent implements self-service through the priority-assigning unit that automatically detects path changes and reassigns priorities without manual intervention. The system monitors communication paths and autonomously adjusts priority assignments when terminals move, enabling the network to self-correct and maintain quality without external control
2Ease of operation
If priority control is implemented using DSCP or IEEE802.1p, then packet prioritization is achieved, but communication quality deteriorates when terminals move and paths change without priority updates
Solution Approach 1:
The patent applies feedback by implementing a monitoring mechanism that detects when communication paths change. The priority-assigning unit receives feedback about path changes and terminal movements, then responds by reassigning priorities to maintain quality of service. This closed-loop feedback system ensures priority control remains effective even as network conditions change
Solution Approach 2:
The patent implements preliminary action by proactively reassigning priorities before communication quality deteriorates. When path changes are detected, the system immediately updates priority assignments in advance, preventing quality degradation rather than reacting after problems occur
Data Source
AI summary
The communication system supports reservation of network resources. The base stations relay packets among the terminals, and perform priority control based on the priority set to the packets. In the terminal, the communication-managing table stores communication information of own terminal and a partner thereof. The packet-transmitting unit, setting priority to the packets, transmits the packets. When link condition of own terminal change, the link-managing unit updates, in order to prevent from quality deterioration of the other terminals, the priority of each of the packets whose source terminal is the own terminal.
