Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in configuring user plane information for multiple sensing nodes at the granularity of per-sensing-service to meet the transmission requirements of sensing services, especially when mobility changes dynamically, leading to inefficiencies in sensing service precision and accuracy.
Innovation Solution
The introduction of an identity of a first sensing service and user plane configuration information associated with the first sensing service facilitates configuring user plane information at the granularity of per-sensing-service, ensuring synchronized user plane configuration for multiple sensing nodes involved in the same service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user plane information is configured for multiple sensing nodes at the granularity of per-sensing-service, then sensing service precision and accuracy are improved, but device complexity and configuration management difficulty increase
Solution Approach 1:
The patent introduces a network element (SMF or PCF) as an intermediary to centrally manage user plane configuration information for sensing services. This intermediary receives sensing service identification from the sensing control network element, retrieves or generates corresponding user plane configuration information, and distributes it to multiple sensing nodes. This mediation approach enables precise per-service configuration while centralizing management complexity in the network rather than at individual nodes.
Solution Approach 2:
The patent creates a universal user plane configuration mechanism that serves multiple sensing nodes across different services through a standardized process. The same configuration management approach (message exchange, information retrieval, distribution) is applied universally to any sensing service, enabling scalable precision without proportionally increasing complexity. The system handles diverse sensing services through a common framework.
2Measurement precision
If user plane configuration is synchronized across multiple sensing nodes for the same service, then sensing service accuracy is improved, but information transmission overhead increases
Solution Approach 1:
The patent implements preliminary action by having the network element retrieve or generate user plane configuration information in advance before distributing it to multiple sensing nodes. The configuration information is prepared centrally based on sensing service identification, and then efficiently distributed to all nodes requiring it. This preliminary preparation reduces the overall transmission overhead compared to individual node configuration requests.
Solution Approach 2:
The patent merges the configuration management process for multiple sensing nodes into a single coordinated operation. Instead of each node independently requesting and receiving configuration information, the network element receives the sensing service identification once, retrieves the configuration information once, and then distributes it to multiple nodes. This merging approach synchronizes configuration across nodes while minimizing redundant information transmission.
