Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ZigBee network management systems lack the ability to obtain network information, such as link failures, making it difficult for operators and users to efficiently manage and diagnose issues within the network.
Innovation Solution
A method is introduced that provides a network object with core parameters at the ZigBee device object layer, allowing for the transmission of network protocol, topology, and failure cause information, enabling efficient management and rapid failure localization by providing this information to the auto-configuration server via TR-069 protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the auto-configuration server uses TR-069 to manage ZigBee devices, then device information can be obtained, but network information (such as link failures) cannot be obtained
Solution Approach 1:
The patent segments network information collection by introducing intermediary nodes (ZigBee router nodes and boundary gateway nodes) that divide the large-scale ZigBee network into manageable segments. Each node collects and reports network information (including link failures) to the boundary gateway, which then forwards it to the auto-configuration server. This segmentation enables comprehensive network information collection while maintaining manageable system complexity.
Solution Approach 2:
The patent introduces boundary gateway nodes as intermediaries between the ZigBee network and the auto-configuration server. These gateway nodes receive network information from ZigBee router nodes, translate it into TR-069 format, and forward it to the server. This intermediary layer resolves the contradiction by enabling network information transmission without requiring direct complex integration between the server and the entire ZigBee network.
2Reliability
If network information is collected from all ZigBee nodes, then comprehensive network management is achieved, but the complexity of information collection and processing increases
Solution Approach 1:
The patent implements segmentation by designating specific router nodes within the ZigBee network as information collection points. Instead of collecting data from all nodes, the system divides the network into segments managed by these router nodes, which then report to boundary gateways. This reduces information collection complexity while maintaining comprehensive network monitoring reliability through distributed collection points.
Solution Approach 2:
The patent applies partial action by having boundary gateway nodes selectively collect network information from specific ZigBee router nodes rather than attempting to collect from every node in the network. This partial collection approach achieves sufficient network management reliability by monitoring key network segments without the excessive complexity of universal node monitoring.
3Adaptability or versatility
If device information is translated to TR-069 format, then device management is enabled, but network information transmission to the server is not possible
Solution Approach 1:
The patent applies universality by designing the boundary gateway node to handle multiple functions: it collects device information in TR-069 format, collects network information from ZigBee router nodes, translates network information into TR-069 format, and forwards both types of information to the auto-configuration server. This multi-functional gateway enables both device and network information transmission through a single universal interface.
Solution Approach 2:
The patent implements parameter changes by transforming network information (such as link failure status, network topology) into the TR-069 parameter format used for device management. The boundary gateway node converts ZigBee-specific network parameters into standardized TR-069 parameters, enabling network information to be transmitted using the same protocol framework as device information.
