Terminal Device Right Management via Direct ACL Speculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal device management systems face inefficiencies due to complex interactions and increased message exchanges when managing multi-level rights, leading to pressure on processing capabilities and network transmission, and reduced performance.
Innovation Solution
A method and device for terminal device management that simplify right management by enabling direct or indirect right speculation, allowing the DM server to process management commands without level-by-level right replacement, reducing message interactions and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the DM server gets ACL of entire subtree to obtain node management right, then the management right is acquired, but the ACL includes great deal of useless information increasing message size
Solution Approach 1:
The patent segments the ACL retrieval process by allowing the DM server to request only the specific ACL information needed for a particular node, rather than retrieving the entire subtree's ACL. This segmentation reduces the quantity of information transmitted while ensuring the necessary management rights are acquired.
Solution Approach 2:
The patent extracts only the necessary ACL components required for node management from the complete ACL structure. By taking out only the relevant permission information needed for the specific operation, the system reduces message size while maintaining the ability to acquire management rights.
2Loss of information
If the DM server sends multiple Get commands to obtain ACL of each node, then the ACL information is obtained, but the number of message interactions increases
Solution Approach 1:
The patent merges multiple separate Get commands into a single consolidated command that retrieves ACL information for multiple nodes simultaneously. This combining approach maintains complete ACL information acquisition while significantly reducing the number of message interactions between the DM server and terminal device.
Solution Approach 2:
The patent creates a universal Get command structure that can retrieve ACL information for multiple nodes in one operation. This multi-functional command serves the purpose of what would otherwise require multiple separate commands, reducing interaction frequency while maintaining information completeness.
3Reliability
If the ACL is replaced level-by-level to endow DM server with operation right, then the right is granted, but the processing complexity and message interactions increase
Solution Approach 1:
The patent implements preliminary action by allowing the DM server to acquire management rights through a direct ACL retrieval operation before the actual node operation is needed. This eliminates the need for level-by-level right replacement during execution, as the rights are already in place through the preliminary ACL get operation.
Solution Approach 2:
The patent uses copying by retrieving and storing the ACL information in a usable format that can be directly applied for node operations. Instead of progressively modifying ACLs at each level, the system copies the necessary permission information in one operation, reducing processing complexity while ensuring rights are properly granted.

AI summary
A method and a device for terminal device management based on right control are provided. The method includes the following steps. A Get command on an access control list (ACL) of a managed node in a device management tree (DMT) from a device management (DM) server is received, where the Get command includes a Unified Resource Identity (URI) of the managed node. It is determined whether the DM server has a direct right of executing the Get command on the managed node. The Get command is processed when it is determined that the DM server has the direct right of executing the Get command on the managed node. The method and the device simplify the complexity of right management, and reduce the number of times of message interaction between the DM server and a terminal device, thereby improving the efficiency and performance of terminal device management.
