Network Slice Connection Grading for Dual-System 5G Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack a solution for implementing network slice grading in dual-system or multi-system environments without interference between network slices, particularly in 5G network slicing, where a dual-Android system with shared SIM cards requires secure and reliable methods to manage slice requests without modifying applications.
Innovation Solution
A method and apparatus that distinguish between different system applications using unique user identities (UIDs) to determine appropriate slice levels and establish connections, employing a slice request grading module to authenticate and encrypt data, ensuring non-interference and security in dual-system environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slicing is implemented in dual-system environments without slice grading, then system complexity is reduced and ease of operation is improved, but network slice interference occurs and security is compromised
Solution Approach 1:
The patent segments network slices by introducing slice level ranges (first slice level range for working system, second slice level range for living system) to separate and manage different network slices independently, preventing interference while maintaining security
Solution Approach 2:
The patent introduces a slice request grading module as an intermediary component that automatically authenticates applications and determines appropriate slice levels, managing the complexity of slice differentiation without requiring application modifications
2Measurement precision
If applications are modified to support network slice grading, then slice level control precision is improved, but ease of manufacture and deployment deteriorate
Solution Approach 1:
The patent enables applications to self-identify their slice levels through automatic authentication using unique user identities (UIDs), eliminating the need for manual application modifications while maintaining precise slice level control
Solution Approach 2:
The patent performs preliminary authentication and slice level determination through the slice request grading module before network slice connection is established, ensuring precise control without requiring application changes during deployment
3Loss of information
If unique user identities are used to distinguish system applications, then slice request differentiation is improved, but information processing complexity increases
Solution Approach 1:
The slice request grading module acts as an intermediary that automatically processes unique user identities (UIDs) to determine slice levels, improving identification accuracy while managing the complexity of identity processing centrally rather than in each application

AI summary
A network slice connection method includes: acquiring a network slice activation request of an application, where the network slice activation request carries an application user identity (UID) and a slice traffic descriptor identity; determining a system to which the application belongs according to the UID, and acquiring a target application package name corresponding to the UID from the system to which the application belongs; determining a first slice level range that corresponds to the target application package name and is allowed to be used by the application; and establishing a network slice connection according to the first slice level range and the slice traffic descriptor identity.
