ACS Device Status Detection via Tr069 Authentication Error
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Tr069 protocol methods for obtaining device status are inefficient and complex, particularly due to varying device types, unnecessary protocol interactions, and system performance consumption, leading to difficulties in managing large numbers of devices effectively.
Innovation Solution
An Auto-Configuration Server (ACS) sends a connection request with a wrong user name and password to a Customer Premises Equipment (CPE), using authentication error status codes to determine online or offline status, simplifying the process to a single HTTP get call and reducing system performance consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed parameter is obtained according to the Tr069 protocol to determine device status, then the device status can be determined, but the process requires multiple HTTP interactions and has low efficiency
Solution Approach 1:
The patent extracts the essential status determination function from the complex Tr069 protocol interaction sequence, reducing it to a single HTTP GET request that checks for the presence of a specific parameter. This extraction eliminates unnecessary protocol steps while preserving the core status detection capability.
Solution Approach 2:
The patent performs preliminary configuration by pre-defining specific parameter paths in the device that indicate online status. By establishing these predetermined parameter locations in advance, the system avoids complex real-time protocol interactions and can quickly determine device status through simple parameter existence checks.
2Measurement precision
If configuration is performed based on device type to obtain a fixed parameter, then the parameter can be obtained, but the functional structure of the network management server becomes complex
Solution Approach 1:
The patent implements a universal status checking mechanism that works across different device types by defining a common parameter path structure. Instead of creating separate configuration logic for each device type, the system uses a unified approach where the parameter existence check serves all device types, thereby reducing server structural complexity.
Solution Approach 2:
The patent changes the approach from device-type-specific parameter values to a universal parameter existence check. By shifting from checking specific parameter values that vary by device type to checking the mere presence of a standardized parameter path, the system simplifies the configuration structure while maintaining accurate status determination.
3Measurement precision
If protocol interaction is performed between CPE and ACS to obtain device status, then the status can be obtained, but system performance is consumed
Solution Approach 1:
The patent extracts only the essential status information from the full Tr069 protocol interaction by implementing a simplified HTTP GET request that checks for parameter existence. This extraction eliminates the need for complete protocol handshakes and multiple message exchanges, significantly reducing system performance consumption while obtaining the necessary status information.

AI summary
The disclosure discloses a method for obtaining a status of a device based on a Tr069 protocol, which includes: an Auto-Configuration Server (ACS) sends a connection request including a wrong user name and password to a Customer Premises Equipment (CPE); and judges a status of the CPE according to whether an authentication error status code returned by the CPE synchronously after receiving the connection request is received. An ACS and a system for obtaining a status of a device based on a Tr069 protocol is further provided by the disclosure. The ACS sends a connection request including a wrong user name and password to a CPE, learns that the CPE is in an online status according to an authentication error status code returned synchronously by the CPE, and when the ACS waits for timeout or receives other status codes, determines that the CPE is in an offline status. Therefore, compared with the related art, the disclosure can obtain the status of the device only by making an HTTP get call, and the method of the disclosure is simple and efficient.
