Access Network Registration Timer for Restricted UE Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks lack mechanisms for managing and controlling third-party subscription data configuration on terminal devices, particularly in non-public networks (NPNs), leading to potential unauthorized access and prolonged usage.
Innovation Solution
Implementing a restricted registration timer and deregistration procedure managed by an access management network element to control terminal device registration, ensuring timely detachment from the network and preventing malicious camping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminal devices perform data compression and encryption before transmission, then transmission efficiency and security are improved, but terminal device power consumption increases
Solution Approach 1:
The system divides the data processing tasks between terminal devices and the network side. Terminal devices perform only necessary local processing while offloading compression and encryption to the network side, reducing terminal power consumption while maintaining transmission efficiency and security
Solution Approach 2:
The network side acts as an intermediary that performs data compression and encryption services for terminal devices. This mediator approach allows terminals to benefit from efficient data transmission without bearing the full processing burden, thus reducing their power consumption
2Quantity of substance
If data is compressed before transmission, then transmission bandwidth is reduced, but data accuracy may be affected
Solution Approach 1:
The system dynamically adjusts compression parameters based on data types and transmission requirements. Different compression algorithms and parameters are applied to different data streams, maintaining data accuracy for critical information while achieving bandwidth reduction for less sensitive data
Solution Approach 2:
Different compression strategies are applied to different parts of the data stream based on their importance and characteristics. Critical data maintains higher fidelity while less critical data undergoes more aggressive compression, optimizing the balance between bandwidth usage and data accuracy
3Reliability
If multiple security protocols are implemented for data protection, then security level is improved, but processing complexity increases
Solution Approach 1:
Multiple security functions including compression, encryption, and authentication are merged into integrated security processing modules on the network side. This consolidation maintains high security levels while reducing overall processing complexity by coordinating these functions in a unified manner rather than as separate independent processes

AI summary
This application provides a communication method and an apparatus. The method includes: An access management network element receives a registration request from a terminal device, and the access management network element obtains configuration type indication information, determines, based on the configuration type indication information, to perform restricted registration, and starts a restricted registration timer. After the restricted registration timer expires, the access management network element initiates a deregistration procedure to deregister the UE from a network. By using the method, the terminal device can be prevented from maliciously camping or accessing another service for a long time. In addition, this solution is simple to implement, and easy to deploy and implement.
