Management Server Grouping Terminals by Delay Variations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, connecting multiple terminals to the same server for real-time processing is hindered by varying delays between terminals and servers, leading to unfairness and inefficiencies due to differences in communication delays and the need for synchronization across multiple servers.
Innovation Solution
A management server system that groups terminals, selects candidate servers based on delay differences, and determines the optimal connection destination server to minimize delay variations among terminals, thereby ensuring fair and efficient connectivity.

Engineering Contradiction Analysis
1Loss of time
If terminals connect to distributed edge servers to reduce communication delay, then communication delay is reduced, but delay variation among terminals in the same group increases leading to unfairness
Solution Approach 1:
The system segments terminals into groups based on their delay characteristics to specific servers. By dividing terminals into multiple groups with similar delay profiles, the system ensures that terminals in the same group experience comparable delays, thus maintaining fairness while still benefiting from reduced communication delays compared to centralized server architecture.
Solution Approach 2:
The system changes the parameter of server selection from static location-based assignment to dynamic delay-based assignment. By continuously monitoring and adjusting server assignments based on actual delay measurements, the system optimizes for both low delay and low delay variation, ensuring fairness among terminals in real-time.
2Productivity
If processing is distributed across multiple servers to handle real-time requirements, then processing capacity increases, but synchronization delays between servers occur reducing efficiency
Solution Approach 1:
The system merges the control function for server assignment into a centralized management server that coordinates all terminal-server connections. This allows distributed processing to occur while maintaining centralized coordination, eliminating synchronization delays between servers by ensuring that terminals in the same group are assigned to the same server for coordinated processing.

AI summary
A management server comprises: a grouping part that performs grouping a plurality of terminals including arbitrary terminals into a same group; a candidate selection part that selects a destination candidate server(s) from among a plurality of predetermined servers; and a connection destination determination part that determines, from among the destination candidate servers, a connection destination server to which the plurality of terminals connect, based on a difference in delays between the plurality of terminals belonging to the same group on a communication to the destination candidate server(s).
