Client Terminal Data Delivery Control via Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data delivery systems face challenges in efficiently delivering data to a large number of client terminal devices without imposing a heavy load on the server device and network, particularly in emergency scenarios like Earthquake Early Warnings, where delays can be critical and infrastructure improvements are costly.
Innovation Solution
A data delivery control system that includes a terminal detection unit in client terminal devices to identify logically proximate devices for data transfer, storing terminal information and using a data delivery control device to manage data delivery, thereby reducing network load by transferring data between proximate devices and optimizing delivery modes such as multicast or unicast based on device states and priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is delivered from server device to a large number of client terminal devices, then data delivery coverage is improved, but load on server device and network increases
Solution Approach 1:
The patent segments the data delivery process by introducing intermediate terminal devices that act as local distribution points. These intermediate devices receive data from the server and forward it to other terminals in their vicinity, dividing the monolithic server-to-all-terminals delivery into multiple smaller server-to-intermediate-to-end-terminal deliveries. This segmentation reduces the load on the server and network by distributing the delivery burden across multiple nodes.
Solution Approach 2:
The patent introduces intermediate terminal devices as mediators between the server and end terminal devices. These intermediaries receive data from the server, store it temporarily, and then forward it to other terminals. This intermediary layer reduces the direct communication burden on the server and network, allowing scalable data delivery to large numbers of terminals without proportionally increasing server load.
2Power
If data is transferred between terminal devices, then load on server device is reduced, but network load may increase due to non-proximate transfers
Solution Approach 1:
The patent applies local quality by having terminal devices transfer data only to other terminals that are logically proximate (local) rather than distributing data globally across the entire network. Each terminal identifies and transfers data to nearby terminals based on network proximity metrics, ensuring that data flows locally within network segments rather than traversing the entire network. This localizes the data transfer load and prevents unnecessary long-distance network traffic.
3Productivity
If terminal devices transfer data to other terminal devices, then data delivery efficiency is improved, but network configuration flexibility becomes challenging
Solution Approach 1:
The patent implements dynamics by making the data transfer routing adaptive and dynamic rather than static. Terminal devices dynamically identify logically proximate terminals based on current network conditions and continuously update their transfer targets. The system adapts to changing network configurations, adding or removing terminals, and varying proximity relationships, allowing efficient data delivery regardless of how the network topology changes over time.
