Solution Overview
Problem
Existing cellular networks lack a practical method for selecting appropriate gNBs or UEs as sensing nodes or assisting nodes for integrated sensing and communication, particularly in beyond 5G networks, where environmental sensing capabilities are being considered.
Innovation Solution
A method is provided for discovering a sensing node by a first network element, which involves querying access network devices based on designated area information and sensing capabilities, using methods such as direct querying, querying via the AMF, or registering area information with the NRF, to determine suitable gNBs or UEs for sensing services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular networks are used for wireless data transmission, then communication capability is provided, but environmental sensing capabilities are not available
Solution Approach 1:
The patent applies multi-functionality by enabling access network devices (gNBs/UEs) to perform both communication and sensing functions. The sensing node selection method allows the network to utilize existing air interface signals for dual purposes: data transmission and environmental sensing, thereby achieving versatility without adding separate dedicated sensing infrastructure
Solution Approach 2:
The patent introduces a first network element as an intermediary that coordinates sensing node selection. This network element queries access network devices to determine their sensing capabilities and designates appropriate nodes for sensing tasks, acting as a mediator between the communication network and sensing functions
2Adaptability or versatility
If sensing services are integrated into cellular networks, then sensing information can be acquired, but the complexity of node selection increases
Solution Approach 1:
The patent implements self-service by enabling access network devices to autonomously indicate their sensing capabilities and service areas. The first network element queries these pre-configured capabilities, allowing nodes to self-describe their sensing attributes without requiring complex manual configuration or capability assessment procedures
Solution Approach 2:
The patent applies preliminary action by having access network devices pre-register their sensing capabilities and service areas with the network before actual sensing tasks are assigned. This advance preparation allows the first network element to quickly query and select appropriate sensing nodes without performing complex real-time assessments
3Quantity of substance
If conventional air interface signals are reused for sensing, then network resources are maximized, but sensing precision may be compromised
Solution Approach 1:
The patent applies local quality by allowing different access network devices to indicate their specific sensing capabilities and service areas. Each node's sensing characteristics are locally optimized and registered individually, enabling the network to select nodes with appropriate local sensing qualities for specific tasks while reusing conventional signals
