Network Device Identity Verification for Private Network Subscription
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring subscription information in private networks lack verification of terminal device identity, leading to potential unauthorized access, as they do not adequately prevent configuration for illegal devices.
Innovation Solution
A method where a network device verifies the identity of a terminal device by matching device identifiers and using random numbers and verification information to ensure only authorized devices receive subscription information, thereby enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user actively requests a server to configure subscription information, then the account opening process is simple and fast, but the network side cannot verify the terminal device identity, leading to potential unauthorized access
Solution Approach 1:
The patent applies preliminary action by having the terminal device send its device identifier to the network side before subscription information configuration. This allows the network side to verify the device identity in advance against a pre-stored second device identifier, ensuring that only authorized devices can receive subscription information while maintaining a simple account opening process
2Adaptability or versatility
If the network side configures subscription information for any device, then the configuration process is flexible and adaptable, but unauthorized devices can access the private network
Solution Approach 1:
The patent implements feedback by having the terminal device send its device identifier to the network side for verification. The network side compares the received identifier with a pre-stored second device identifier and only configures subscription information when they match. This feedback mechanism ensures that subscription information is configured adaptively for legitimate devices while preventing unauthorized access

AI summary
Example subscription information configuration methods and a communications device are described. One example method includes receiving a first device identifier by a network device from a first terminal device in a first access mode and receiving a second device identifier from a second terminal device in a second access mode. The network device determines whether the first device identifier matches the second device identifier to identify legality of the first terminal device. If the first device identifier matches the second device identifier, it indicates that the first terminal device is a legal terminal device. The network device sends subscription information of the first terminal device to the first terminal device in the first access mode, so that the first terminal device successfully accesses a network by using the subscription information.
