Wireless Network Slice Synchronization Through Peer Acknowledgments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks fail to effectively coordinate the parallel operations of different network slices, leading to unsynchronized delivery of data communication services.
Innovation Solution
Implement synchronized wireless network slicing by using a first wireless network slice to transfer an output to a second slice, which acknowledges and authorizes the output before using it to deliver a data communication service, and vice versa, with the slices operating within a Network Function Virtualization Infrastructure (NFVI) and utilizing peer-to-peer signaling for synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless network slices operate in parallel independently, then processing speed and service delivery are improved, but synchronization between slices deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where network slice instances exchange acknowledgment messages to confirm successful processing of data packets. When a slice instance receives and processes a packet from another slice, it sends an acknowledgment back, creating a closed-loop feedback system that ensures synchronized operation while maintaining parallel processing capabilities
Solution Approach 2:
The patent introduces an intermediary coordination mechanism through standardized interfaces and protocols that mediate between independently operating network slice instances. This intermediary layer enables synchronization without requiring direct coupling between slices, allowing parallel operation while maintaining coordination through standardized message exchange
2Stability of the object's composition
If network slices are coordinated through centralized control, then synchronization is improved, but system complexity and processing overhead increase
Solution Approach 1:
The patent segments the coordination function by allowing each network slice instance to independently manage its own synchronization state and exchange messages directly with other slice instances. This segmentation eliminates the need for a centralized coordination entity, reducing system complexity while maintaining synchronization through distributed peer-to-peer communication
Solution Approach 2:
The patent enables network slice instances to self-coordinate through autonomous message exchange and acknowledgment mechanisms. Each slice instance independently tracks its own processing state and initiates synchronization messages when needed, eliminating reliance on external centralized control and reducing overall system complexity
3Reliability
If acknowledgment messages are exchanged between slices, then synchronization reliability is improved, but communication overhead increases
Solution Approach 1:
The patent implements partial acknowledgment where slice instances exchange acknowledgment messages selectively based on the criticality of data packets and processing states. Not all packets require full acknowledgment sequences, allowing the system to maintain reliability for critical operations while reducing communication overhead for less critical data flows

AI summary
A first wireless network slice executes a first slice input and generates a first slice output. The first slice transfers the first slice output to a second wireless network slice. The second slice receives and authorizes the first slice output and transfers a first acknowledgement to the first slice. The first slice receives the first acknowledgement and responsively uses the first slice output to deliver a data communication service. The second slice executes a second slice input and generates a second slice output. The second slice transfers the second slice output to the first slice. The first slice receives and authorizes the second slice output and transfers a second acknowledgement to the second slice. The second slice receives the second acknowledgement and responsively uses the second slice output to deliver the data communication service.
