Engineering Contradiction Analysis
1Reliability
If sensing technologies are implemented as standalone systems separate from communication networks, then sensing functionality can be provided, but resource efficiency deteriorates and integrated sensing data reliability is degraded
Solution Approach 1:
The patent merges sensing functions with communication network functions by integrating sensing reference signals into existing communication procedures. The sensing function is embedded within the 5G core network and radio access network, allowing sensing operations to share resources with communication activities. This integration eliminates the need for separate standalone sensing systems, thereby improving resource efficiency while maintaining sensing data reliability through unified network management.
2Measurement precision
If reservation-based sensing is implemented within mobile communication networks, then sensing accuracy and resource allocation efficiency are improved, but network complexity increases
Solution Approach 1:
The patent implements multi-functionality by enabling the mobile communication network to perform both communication and sensing functions through a unified architecture. Existing network elements such as the core network, radio access network, and user equipment are designed to handle both communication tasks and sensing operations. The sensing reference signals are transmitted over existing communication channels, allowing the same infrastructure to serve dual purposes. This approach improves sensing accuracy through dedicated reservation mechanisms while avoiding the complexity of entirely separate sensing infrastructure.

AI summary
A reservation-based sensing method may comprise receiving, by a core network and using at least one first network function (NF), a sensing request from a sensing client; negotiating, by the core network and using at least one second NF, a sensing policy for performing a sensing operation corresponding to the sensing request with the sensing client; and communicating, by the core network and using the at least one second NF, with a RAN or a UE, so that the sensing operation corresponding to the sensing request is performed by applying the sensing policy determined based on the negotiation, wherein the sensing request includes reservation information for performing the sensing operation.
