Command Node Selection in Heterogeneous Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous communication systems, smooth handoffs between access nodes operating under different communication technologies and protocols are challenging due to incompatibilities, leading to redundant or conflicting command services for mobile nodes, which increases overhead and complicates handover processes.
Innovation Solution
A method where a mobile node selects a commanding access node by sending a registration message, specifying which access node should provide command services, thereby avoiding redundant or conflicting commands and optimizing handover processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple access nodes provide command services to mobile nodes in heterogeneous networks, then comprehensive coverage and service availability are improved, but redundant or conflicting commands are generated increasing overhead and complicating handover processes
Solution Approach 1:
The patent introduces a command node selection mechanism that designates a single commanding access node among multiple available access nodes. This intermediary selection process resolves the contradiction by filtering out redundant command sources while maintaining comprehensive service coverage through the coordinated selection of one primary command provider from the heterogeneous network ensemble.
2Area of stationary object
If multiple access nodes transmit command services to mobile nodes, then service coverage is improved, but overhead increases due to redundant or conflicting commands
Solution Approach 1:
The patent extracts and eliminates redundant command transmissions by implementing a command node selection mechanism. Instead of allowing all access nodes to transmit commands simultaneously, the system identifies and designates a single commanding access node, thereby removing the harmful redundancy while preserving the beneficial service coverage area through the selected node's comprehensive command provision.
3Reliability
If handoff between access nodes is triggered by signal quality metrics, then connection reliability is improved, but handover frequency increases leading to increased overhead and system complexity
Solution Approach 1:
The patent introduces a command node selection intermediary that stabilizes handover processes in heterogeneous networks. By designating a single commanding access node based on comprehensive criteria beyond just signal quality, this intermediary reduces unnecessary handover triggering while maintaining connection reliability, thereby improving overall handover efficiency and reducing system overhead.
