Communication Node Handover Association Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication systems, there is no structure for identifying and preferentially handing over a user equipment (UE) to its original communication node apparatus after a handover, leading to inefficient load distribution and potential communication service instability.
Innovation Solution
A communication node apparatus is configured to transmit association information during handover processing, allowing for the identification of the original communication node apparatus and enabling preferential handover of the UE back to that node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handover processing is performed based only on radio field intensity, then handover decisions are simple to make, but the system cannot identify the original communication node and cannot perform preferential handover back to it
Solution Approach 1:
The system performs preliminary action by storing association information between the UE and its original communication node before handover occurs. This association information is preserved and used later to enable preferential handover back to the original node, solving the problem of losing track of the original communication node.
Solution Approach 2:
Association information acts as an intermediary element that connects the UE with its original communication node. This intermediary carries identification data that enables the system to recognize and prioritize the original node during handover decisions, without complicating the basic handover mechanism.
2Productivity
If no association information is transmitted during handover, then handover processing is simple and fast, but flexible handover control and preferential reconnection to original nodes cannot be achieved
Solution Approach 1:
The system applies partial action by transmitting association information selectively rather than in all handover scenarios. This allows the system to maintain simple and fast handover processing for basic cases while enabling flexible handover control when needed, such as when preferential reconnection to the original node is desired.
Solution Approach 2:
The system changes parameters by adding association information to handover messages only when required for preferential handover. This parameter modification allows flexible handover control without significantly impacting overall handover processing speed, as the additional information is transmitted only in specific scenarios.
3Productivity
If UEs are handed over frequently between different communication nodes for load distribution, then load balancing improves, but communication service stability deteriorates due to unnecessary handovers
Solution Approach 1:
The system implements feedback by using association information to monitor and track UE connections with their original communication nodes. This feedback mechanism enables the system to recognize when a UE should preferentially reconnect to its original node, thereby reducing unnecessary handovers and improving communication service stability while maintaining load distribution benefits.

AI summary
A communication node apparatus for providing a public network communication service includes a transmission unit for transmitting, in a case of handing over a communication apparatus existing under the communication node apparatus to a different communication node apparatus, association information for associating the communication apparatus with an own node, to the communication apparatus or the different communication node apparatus. The association information is information to be used in determining a next handover destination for the communication apparatus handed over to the different communication node apparatus, and is information that makes an effect of increasing a possibility of being selected as the next handover destination.
