Access Control Device Subscription Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, there is a challenge in ensuring the legality of changes in subscription information, particularly when terminals are stolen and unauthorized changes are made.
Innovation Solution
A subscription information processing method where an access control device obtains authorization information from a target network device, and only processes subscription information for a second terminal if the identifier matches the first terminal and if the authorization information is valid, thereby preventing unauthorized changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the access control device processes subscription information based on unilateral terminal requests, then the ease of operation is improved, but the reliability of subscription information processing deteriorates due to potential illegal access
Solution Approach 1:
The access control device obtains authorization information from the target network device before processing subscription information. This preliminary authorization step ensures that only legally authorized operations are performed, preventing unilateral illegal access while maintaining operational efficiency for legitimate requests
2Reliability
If identity authentication is performed on the terminal, then the reliability of subscription information processing is improved, but the device complexity increases
Solution Approach 1:
The target network device serves as an intermediary that provides authorization information to the access control device. This intermediary mechanism enables reliable identity verification and authorization without requiring the access control device to implement complex authentication protocols itself, thus maintaining reliability while limiting complexity growth

AI summary
A subscription information processing method and apparatus, and a device. The method includes: An access control device obtains authorization information from a target network device, where the authorization information includes an identifier of a first terminal and authorization operation indication information for subscription information of the first terminal; the access control device obtains a subscription information processing request from a second terminal, where the subscription information processing request includes an identifier of the second terminal; and the access control device processes subscription information corresponding to the identifier of the second terminal based on the authorization operation indication information in response to the identifier of the first terminal matching the identifier of the second terminal.
