Solution Overview

Problem

Existing wireless communication systems, particularly in the 5G era, face challenges in providing effective sensing services for objects using base stations and terminals designed primarily for human-centric communications.

Innovation Solution

The proposed method involves an operation method of the access and mobility management function (AMF) in a wireless communication system, which includes receiving a subscription request from a sensing function, obtaining subscription information for user equipment (UE), and identifying base stations or UEs that can support sensing services. This information is then transmitted to the sensing function to facilitate the provision of sensing services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If base stations and terminals designed for human-centric communications are used for sensing services, then existing communication infrastructure can be utilized, but the sensing service effectiveness is insufficient

Engineering Contradiction:

Improvesensing service supportVSAvoidsensing service effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent enables base stations and terminals to perform both communication functions and sensing functions using the same hardware infrastructure. The AMF identifies UEs that support sensing services and configures them to provide sensing data, allowing dual functionality without requiring separate dedicated sensing equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The Access and Mobility Management Function (AMF) acts as an intermediary that bridges the communication network and sensing services. It receives sensing service subscription requests, identifies suitable UEs, configures sensing measurements, and forwards sensing data to the appropriate network functions, enabling effective sensing service delivery.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If sensing services are added to existing communication systems, then service versatility improves, but system complexity increases

Engineering Contradiction:

Improveservice typesVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent leverages existing communication infrastructure (base stations, terminals, AMF) to provide both communication and sensing services, avoiding the need for separate dedicated sensing networks and reducing overall system complexity while maintaining versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system utilizes existing sensing capabilities already present in communication-equipped UEs and base stations, allowing these devices to self-configure for sensing services through AMF management without requiring entirely new device architectures.

Inventive Principle:

Principle #25Self-service

3Area of stationary object

If all UEs are configured for sensing services, then sensing coverage is maximized, but resource consumption increases

Engineering Contradiction:

Improvesensing coverageVSAvoidenergy consumption

Core Design Contradiction:

Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

The AMF identifies and configures sensing services only on specific UEs that are located in areas where sensing is actually needed, based on subscription requests and location information. This selective configuration ensures sensing coverage where required while avoiding unnecessary energy consumption on UEs not requiring sensing services.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Rather than configuring all UEs for sensing, the system applies partial action by selectively enabling sensing only on UEs that match the sensing service requirements and location criteria, optimizing the balance between coverage and resource consumption.

Inventive Principle:

Principle #16Partial or excessive action
