1Adaptability or versatility
If sensing techniques are implemented separately from communication systems, then sensing operations can be performed independently, but resource efficiency deteriorates and reliability of integrated sensing data degrades
Solution Approach 1:
The patent merges sensing operations with the communication system by having the access and mobility management function select sensing entities from user equipment within the communication network. This integration allows sensing to be performed using existing communication infrastructure and protocols, improving resource efficiency and data reliability while maintaining operational flexibility through standardized selection criteria.
2Measurement precision
If multiple user equipments are utilized for sensing in a specific area, then sensing accuracy improves, but system complexity increases
Solution Approach 1:
The access and mobility management function serves as an intermediary that simplifies the complexity of coordinating multiple sensing entities. It receives sensing request information, selects appropriate user equipment based on area and criteria, and manages the sensing operations centrally, thereby improving sensing accuracy through multiple entities without requiring complex distributed coordination among the entities themselves.
3Manufacturing precision
If sensing rule information is converted into information elements for network functions, then sensing control precision improves, but processing time increases
Solution Approach 1:
The patent transforms sensing rule information into standardized information elements with specific parameters that can be directly processed by network functions. This parameter transformation enables precise control of sensing operations through structured data formats while optimizing processing efficiency by converting complex sensing requirements into manageable information elements that follow standardized communication protocols.
