Solution Overview
Problem
Conventional G.hn domain master nodes face challenges in effectively managing energy-saving modes, leading to inefficient power consumption and difficulty in synchronizing idle states among nodes, which hinders optimal energy savings.
Innovation Solution
The implementation of an idle scheduling method where the domain master node synchronizes energy-saving modes with intra-domain ordinary nodes, entering into low-power or idle modes based on valid scheduling information, and utilizes buffers to manage downlink data during idle states, ensuring efficient power management and synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the domain master node continuously monitors and manages idle scheduling for all ordinary nodes, then the idle state synchronization and energy-saving management are maintained, but the domain master node's power consumption increases and prevents it from entering energy-saving modes
Solution Approach 1:
The patent divides the domain master node's functionality into two parts: ordinary nodes autonomously manage their own idle scheduling based on local conditions, while the domain master node only performs coordination and information collection. This segmentation allows ordinary nodes to operate independently in energy-saving modes without requiring continuous active management from the domain master node, thus reducing its power consumption while maintaining synchronization capability.
2Loss of energy
If ordinary nodes enter idle mode to save energy, then power consumption is reduced, but the domain master node cannot save energy due to the need to manage and coordinate these idle states
Solution Approach 1:
The patent implements self-service by enabling ordinary nodes to autonomously determine their own idle scheduling based on their local traffic patterns and energy requirements. Nodes can independently enter and exit idle modes without requiring the domain master node to actively manage each transition, thereby reducing overall network energy consumption while simplifying the domain master node's operational burden to merely coordinating information exchange.
3Reliability
If the domain master node actively manages idle scheduling for all nodes, then idle state coordination is achieved, but the complexity of the domain master node increases
Solution Approach 1:
The patent segments the scheduling management responsibility from the coordination function. Ordinary nodes perform local scheduling decisions based on their needs, while the domain master node only handles information collection and coordination messaging. This segmentation maintains reliable idle scheduling coordination across the network while significantly reducing the operational complexity of the domain master node.
4Loss of energy
If the domain master node enters idle mode to save energy, then its power consumption is reduced, but it cannot effectively manage or synchronize the idle states of ordinary nodes
Solution Approach 1:
The patent enables the domain master node to enter idle mode by implementing self-service mechanisms where ordinary nodes autonomously manage their own idle scheduling. This eliminates the need for the domain master node to remain active for management purposes, allowing it to conserve energy while ordinary nodes independently maintain reliable idle state coordination based on their local conditions and pre-established scheduling policies.
