Remote Configuration Device for Seamless Terminal Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing voice communication systems, users lack the ability to update configuration data on their own terminals, leading to increased workload for service providers and reduced user convenience, especially when scaling the system or transferring terminals between divided systems, which can result in failed operations and connectivity issues.
Innovation Solution
A communication system management method that allows users to update provisioning data on their terminals using a remote configuration device, enabling seamless movement of communication terminals between multiple systems without failure by providing access to update configuration data and managing terminal information across different call control systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system provider manages all configuration data centrally in the provisioning server, then system security is maintained, but the workload of the provider increases and user convenience is reduced
Solution Approach 1:
The patent divides the configuration management function into two segments: the provisioning server maintains centralized control for security, while the remote configuration device enables user-side operations. This segmentation allows users to update configuration data locally without compromising system security, resolving the contradiction between security and ease of operation.
Solution Approach 2:
The remote configuration device acts as an intermediary between the user and the provisioning server. It receives configuration update requests from users, validates them against security policies, and only accepts updates if they meet security criteria. This intermediary mechanism enables user convenience while maintaining system security through provider-controlled validation.
2Ease of operation
If configuration data updates are opened to users, then user convenience is improved, but the risk of operational failure increases
Solution Approach 1:
The system implements a feedback mechanism where the provisioning server receives configuration update requests from the remote configuration device, validates them against predefined security criteria, and provides feedback by accepting or rejecting the updates. This feedback loop ensures that user-initiated updates do not compromise system security, maintaining operational stability while enabling user convenience.
Solution Approach 2:
The system performs preliminary validation of configuration update requests before applying them. The provisioning server checks whether the update request meets security criteria in advance, and only if validation passes does it proceed to apply the update. This preliminary action prevents potentially harmful updates from reaching the system, ensuring operational stability while allowing legitimate user updates.
3Device complexity
If terminal transfer between divided systems is performed in-series, then system architecture is simplified, but the failure possibility of the operation increases
Solution Approach 1:
The patent applies preliminary action by having the remote configuration device notify the provisioning server of the intended terminal transfer before actually executing it. The provisioning server validates the transfer request and only accepts it if security criteria are met. This preliminary validation ensures that only authorized transfers proceed, preventing failures while maintaining architectural simplicity.
Solution Approach 2:
The system implements feedback in the terminal transfer process by having the remote configuration device send notifications to the provisioning server about transfer intentions. The provisioning server responds with acceptance or rejection based on security validation. This feedback mechanism ensures reliable transfers while keeping the architecture simple, as the flow remains linear but with added validation steps.

AI summary
[Problem] To conduct a process of moving a designated communication terminal belonging to a first communication system so as to belong to a second communication system without errors. [Solution] A management device is provided, which deletes information on a communication terminal of a first configuration device and then adds information of the communication terminal to the second configuration device. The management device is provided with an interface unit and a control unit. The interface unit obtains a first configuration file which stores a configuration data on a communication terminal belonging to a first communication system, and a second configuration file which stores a configuration data on a communication terminal belonging to a second communication system. The control unit deletes a configuration data of a designated communication terminal from the obtained first configuration file, and adds a configuration data of the designated communication terminal to the obtained second configuration file.
