Parameter Subtree Iterator for Server Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication protocols between a server device and customer devices, such as the TR-069 Management Protocol, face issues with network load and latency due to inefficient data retrieval methods, particularly when dealing with large arrays of parameters, leading to scalability concerns and excessive bandwidth usage.
Innovation Solution
The method involves instantiating an iterator on the customer device for a parameter-sub-tree, allowing for efficient data retrieval by specifying a start and end value, reducing the need for unnecessary data transmission and improving response times by managing a subrange of parameter values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the existing TR-069 protocol methods are used to retrieve parameter values, then complete parameter data can be obtained, but network load and bandwidth usage increase excessively
Solution Approach 1:
The patent segments the parameter retrieval process into two distinct phases: a configuration phase where the ACS transmits the complete parameter-sub-tree structure and iterator definitions to the CPE, and an execution phase where the CPE performs local iteration and transmits only the specific parameter values requested. This segmentation allows the network to carry minimal data during the execution phase, resolving the contradiction between obtaining complete parameter data and reducing network bandwidth consumption.
2Loss of information
If all parameter values in a parameter-sub-tree are transmitted, then the server device receives complete data, but response time and latency increase
Solution Approach 1:
The patent extracts only the necessary parameter values from the complete parameter-sub-tree at the CPE side. The iterator mechanism allows the ACS to specify which parameters are needed, and the CPE extracts and transmits only those specific values rather than all parameters in the sub-tree. This extraction approach maintains data completeness for requested parameters while significantly reducing transmission time and latency.
3Adaptability or versatility
If the parameter retrieval method supports large arrays of parameters, then comprehensive device management is achieved, but scalability becomes problematic due to network load
Solution Approach 1:
The patent introduces dynamic iterators that can be configured at runtime to adapt to different parameter retrieval needs. The ACS can dynamically create iterators with specific start and end values for array parameters, allowing flexible querying of large parameter sets without transmitting unnecessary data. This dynamic approach enables comprehensive device management capability while maintaining system scalability by keeping network traffic proportional to actual information needs.

AI summary
A method is described for managing a communication between a server device and a customer device. The method comprises interchanging between the server device and the customer device one or more parameter messages that are comprising a parameter description for a parameter name. The parameter description does consist of an hierarchical tree-like structure of characters with each level separated by a predefined character (dot). The method further comprises a step of instantiating by an instantiating device of the customer device, an iterator associated to an index, for a next level of a parameter-sub-tree being part of the global parameter description, and a step of recalling an object array for the parameter-sub-tree with the next level having different values for its index starting with a predefined start-value and ending with a predefined end-value.
