Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control mechanisms in LTE systems are inflexible and unable to effectively extend to accommodate the growing diversity of user equipment (UE) types and services, complicating access control decisions.
Innovation Solution
An access control method and device that determine an access control group set including access control object information and corresponding parameters, allowing for direct extension of access control objects and enforcement of access control parameters, thereby improving extensibility and convenience in managing diverse UE and service types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing access control mechanisms (ACB, EAB, ACDC) are used in LTE systems, then access control can be enforced for current UE types and services, but the mechanism becomes inflexible and difficult to extend for new UE types and services
Solution Approach 1:
The patent introduces a unified access control group set structure that can accommodate multiple UE types and service types through a single framework. Instead of maintaining separate access control mechanisms for different scenarios, the system uses a universal group set that can be configured to handle various access control needs, thereby improving extensibility while reducing overall system complexity
Solution Approach 2:
The patent segments the access control objects into different groups based on UE types and service types, with each group having its own access control parameters. This segmentation allows the system to manage diverse access control requirements in an organized manner, making it easier to extend to new UE types by simply adding them to appropriate groups without affecting existing control logic
2Adaptability or versatility
If multiple separate access control mechanisms are maintained for different UE types and services, then specific access control requirements can be met, but the system becomes complicated and difficult to manage
Solution Approach 1:
The patent merges multiple separate access control mechanisms into a single unified framework. By combining ACB, EAB, and ACDC into one access control group set structure, the system simplifies management while maintaining the ability to support diverse UE and service types. Operators can manage access control through a single interface rather than multiple separate systems
Solution Approach 2:
The patent uses parameter changes to adapt the access control mechanism to different UE types and services. By modifying parameters such as access control group indices, barring factors, and timer values within the unified framework, the system can accommodate various access control requirements without changing the fundamental structure, thereby improving ease of operation

AI summary
An access control and device for enhancing the extendibility of access control mechanisms, thereby further facilitating the extendibility of access control methods and types for the diversified development of terminal types and service types. The access control method comprises: a user equipment (UE) determines an access control group set including access control target information; the UE determines the access control parameter corresponding to the access control group set; the UE performs access control according to the access control parameter.
