Communication Device Path Management for Dual Connectivity Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Dual Connectivity scenarios where main and secondary base stations belong to different IP subnets, communication via a Gateway Router (GWR) leads to excessive bandwidth consumption, and existing solutions require lengthy setup operations on base stations when using Layer 3 devices.
Innovation Solution
A communication device with multiple ports that uses a setting table to dynamically change communication paths by checking packet destinations and updating settings based on received packets, allowing for shorter paths without additional base station settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication via Gateway Router (GWR) is used for Dual Connectivity between base stations in different IP subnets, then communication between different communication domains is enabled, but communication band is excessively consumed
Solution Approach 1:
The invention introduces a communication device as an intermediary between base stations in different IP subnets. This device includes a path management unit that learns communication paths from packets and a packet forwarding unit that forwards packets through optimized paths, eliminating the need for GWR and reducing bandwidth consumption while maintaining inter-domain communication capability
Solution Approach 2:
The invention implements dynamic path management where the communication device continuously learns and updates communication paths based on actual packet flows. The path management unit dynamically adjusts forwarding decisions based on learned information, enabling adaptive optimization of communication paths to reduce bandwidth consumption while maintaining connectivity
2Loss of energy
If Layer 3 router is inserted into Layer 2 network to separate subnet, then communication band consumption is reduced, but additional setting on base stations is required and setting operation takes long time
Solution Approach 1:
The invention implements self-service configuration where the communication device automatically learns communication paths by monitoring packets and builds its own forwarding tables without requiring manual configuration on base stations. The path management unit autonomously performs path learning and forwarding decision making, eliminating the need for time-consuming manual settings while maintaining efficient bandwidth usage
Solution Approach 2:
The invention employs feedback mechanisms where the communication device continuously monitors actual packet flows and uses this information to update its path management tables. This feedback loop enables the system to automatically adapt to changing network conditions and optimize paths without requiring manual reconfiguration, significantly reducing setup time

AI summary
An object is to provide a communication device, a communication method, and a program that make it possible to suppress an increase in the communication band due to communication via a GWR when Dual Connectivity is implemented, without making an additional setting on base stations. A communication device according to the present invention enables a communication packet to be transferred through a path that is shorter than conventional paths, and can therefore suppress an increase in the communication band. Also, this short cut of the communication path need only be set on the communication device, and need not be additionally set on the base stations.
