Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication traffic offloading techniques, such as those described in PTL 1, face difficulties in offloading traffic when terminals cannot access multiple wireless systems, leading to inefficiencies in network congestion management.
Innovation Solution
A communication device and method that identify terminal attributes based on message information to determine whether to connect to a base station, allowing for the transmission of messages to a virtual network node operated by a virtual machine, enabling traffic offloading even when terminals do not support multiple wireless systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication traffic is offloaded by switching paths between different wireless systems, then network congestion is alleviated, but terminals that cannot access multiple wireless systems cannot benefit from this offloading
Solution Approach 1:
The patent introduces a base station as an intermediary that performs traffic offloading on behalf of terminals. The base station identifies terminal attributes from connection messages, determines appropriate network paths, and redirects traffic accordingly. This mediator approach allows terminals with limited wireless system support to still benefit from intelligent traffic offloading, as the base station handles the complexity of multi-system path selection without requiring terminal capability
Solution Approach 2:
The patent changes the parameter of who performs the offloading decision from the terminal to the base station. By shifting the intelligence from the terminal side to the network side, the system can implement sophisticated traffic management based on terminal attributes without requiring terminals to support multiple wireless systems or complex decision-making capabilities
2Adaptability or versatility
If communication traffic increases due to spread of smartphones and smart devices, then network coverage and service availability improve, but network congestion worsens
Solution Approach 1:
The patent segments communication traffic into different paths based on terminal attributes and network conditions. By dividing the traffic flow and routing different types of traffic through different wireless systems or network paths, the system can handle increased traffic volume from smartphones and smart devices without causing congestion in any single path
Solution Approach 2:
The patent implements dynamic traffic offloading where the base station continuously monitors terminal attributes, connection messages, and network conditions to adaptively determine the optimal communication path. This dynamic approach allows the network to respond to increasing traffic demands from various devices by flexibly routing traffic through available paths, maintaining productivity despite growing device connectivity

AI summary
A communication device for offloading communication traffic includes: first means for identifying an attribute of a terminal based on information included in a message transmitted by the terminal to connect to a wireless network; and second means for determining whether or not to connect a base station that has received the message from the terminal and the terminal based on the identified attribute, wherein the second means is capable of transmitting the message transmitted by the terminal having a predetermined attribute to a virtual network node operated by a virtual machine.
