Wireless Backhaul Node Configuration Master Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication coverage extension systems, reconfiguring functionalities such as parental control is difficult when no master node is designated, requiring individual reconfiguration of all nodes in the network, which is inefficient.
Innovation Solution
A method and system that identify nodes directly connected to the gateway and select a single node to serve as the configuration master, allowing the configuration to be sent to all other nodes in the backhaul subnetwork, using protocols like DHCPv4, DHCPv6, neighbor discovery protocol, or IP packet methods to determine node connections and select the node with optimal performance or branch size for configuration distribution.

Engineering Contradiction Analysis
1Adaptability or versatility
If no master node is designated in the backhaul subnetwork, then nodes can be freely connected to the gateway, but reconfiguration of functionalities becomes difficult requiring individual reconfiguration of all nodes
Solution Approach 1:
The system automatically designates a master node based on predefined criteria (such as node ID, connection status, or network position) without requiring manual intervention. The designated master node then automatically distributes configuration updates to all other nodes in the backhaul subnetwork, enabling self-managed reconfiguration and eliminating the need for individual node reconfiguration.
Solution Approach 2:
The master node acts as an intermediary between the configuration source and all other nodes in the network. Configuration updates are first formulated at the master node and then systematically propagated to all slave nodes, simplifying the reconfiguration process from individual node-level operations to a single centralized action.
2Reliability
If multiple nodes are directly connected to the gateway, then network redundancy is improved, but selecting a configuration master becomes complex requiring evaluation of multiple nodes
Solution Approach 1:
The system uses changeable selection criteria such as node ID values, connection timestamps, or network position parameters to dynamically determine the master node. By establishing clear parameter-based rules (e.g., 'the node with the highest node ID directly connected to the gateway becomes master'), the complexity of selecting among multiple redundant nodes is eliminated while preserving network reliability.
3Ease of operation
If a master node is centrally designated, then configuration distribution is simplified, but the system loses flexibility in node selection
Solution Approach 1:
The master node designation is not fixed but dynamic, allowing the system to adapt to changing network conditions. The master node can be reassigned based on updated criteria such as node availability, connection status, or performance metrics, maintaining both centralized configuration simplicity and system adaptability.

AI summary
A method for configuring a wireless communication coverage extension system is described. The latter comprises a backhaul subnetwork in tree form comprising a plurality of interconnected nodes. At least two nodes directly connected to an internet access gateway are identified among the nodes of the backhaul subnetwork. A single node is selected from the at least two identified nodes to be the node through which a configuration of the wireless communication coverage extension system is defined. The configuration of the wireless communication coverage extension system defined is then sent from the selected node to all the other nodes of the backhaul subnetwork.
