Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network resources are divided into network slices with high isolation between slices, then network slice isolation is improved, but device complexity increases due to multiple access management function instances
Solution Approach 1:
The patent segments the access management function into multiple independent instances (AMF 1, AMF 2, etc.), each responsible for specific network slices. This segmentation enables high isolation between network slices by distributing them across different AMF instances, while the modular architecture manages the complexity through standardized interfaces and protocols for parallel registration.
Solution Approach 2:
The patent creates a universal registration mechanism that works across multiple AMF instances simultaneously. The user equipment can perform parallel registration with multiple AMF instances using a standardized procedure, allowing the system to handle multiple network slices through a unified approach rather than requiring slice-specific registration procedures for each AMF instance.
2Productivity
If parallel registration to multiple network slices is implemented, then productivity is improved, but device complexity increases due to multiple RRC connections
Solution Approach 1:
The patent performs preliminary actions by establishing multiple RRC connections in parallel during the initial registration phase. The user equipment simultaneously sets up RRC connections with multiple AMF instances and includes registration requests for multiple network slices in the same RRC connection setup complete message, eliminating the need for sequential registration procedures.
Solution Approach 2:
The patent merges multiple registration operations into a single parallel execution framework. Multiple registration requests for different network slices are combined and transmitted simultaneously through parallel RRC connections, and the responses from multiple AMF instances are aggregated in a unified manner, improving productivity while managing complexity through the standardized merging process.
3Adaptability or versatility
If multiple access management function instances are used for network slices, then adaptability is improved, but loss of information increases due to distributed registration management
Solution Approach 1:
The patent implements feedback mechanisms where each AMF instance provides registration status and network slice information back to the user equipment through standardized response messages. The user equipment maintains a unified view of registration status across all AMF instances by processing feedback from each instance, ensuring no registration information is lost despite the distributed architecture.
Solution Approach 2:
The patent introduces the RRC layer as an intermediary that coordinates communication between the user equipment and multiple AMF instances. The RRC connection setup complete message serves as a mediator that carries registration requests to multiple AMF instances simultaneously, and the registration accept messages from different AMF instances are aggregated through the RRC layer, preventing information loss in the distributed system.
