Solution Overview

Problem

In the context of ranging-based services, terminals face challenges in determining whether to prioritize new relative position measurement requests over ongoing processes, especially when processing capabilities are limited, leading to inefficiencies in resource allocation and service delivery.

Innovation Solution

A method and apparatus that determine the priority of relative position measurement requests based on service type, latency requirements, and processing capabilities, allowing terminals to selectively receive or reject requests to optimize simultaneous and ongoing measurement processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If terminals accept all relative position measurement requests, then measurement coverage is improved, but processing efficiency deteriorates due to limited processing capabilities

Engineering Contradiction:
Improvemeasurement coverageVSAvoidprocessing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent changes the parameter of request acceptance from binary (accept/reject) to priority-based (high/medium/low priority levels). By introducing priority parameters and corresponding handling strategies, the system can differentiate between important and less important requests, improving processing efficiency while maintaining comprehensive measurement coverage through selective acceptance based on priority thresholds.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamic request handling where the terminal's processing state adapts to incoming requests. The system dynamically adjusts its behavior based on current processing capacity, ongoing measurements, and request priorities. This dynamic approach allows the terminal to optimize between accepting new requests and maintaining ongoing measurements, resolving the contradiction between coverage and efficiency.

Inventive Principle:
Principle #15Dynamics

2Reliability

If terminals prioritize high-priority measurement requests, then service quality is improved, but resource allocation complexity increases

Engineering Contradiction:
Improveservice qualityVSAvoidresource allocation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent simplifies resource allocation by changing the complexity parameter through standardized priority levels (high/medium/low) and corresponding predefined handling rules. Instead of complex continuous optimization, the system uses discrete priority parameters with clear decision logic, reducing allocation complexity while maintaining service quality through systematic priority-based scheduling.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent segments the measurement request handling into distinct priority levels (high, medium, low) with specific handling strategies for each level. This segmentation simplifies the resource allocation process by breaking down the complex decision-making into manageable segments, where each priority level has predetermined rules, thereby reducing overall system complexity while ensuring service quality.

Inventive Principle:
Principle #1Segmentation

3Productivity

If terminals process multiple simultaneous measurement requests, then measurement throughput is improved, but measurement precision deteriorates due to resource contention

Engineering Contradiction:
Improvemeasurement throughputVSAvoidmeasurement accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent implements dynamic resource allocation that adjusts processing intensity based on request priority and current system state. When high-precision measurements are detected, the system dynamically reduces concurrent processing to minimize resource contention, while maintaining high throughput for lower-priority requests. This dynamic adjustment resolves the contradiction by adapting processing capacity to precision requirements in real-time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies different processing quality levels to different requests based on their priority and type. High-priority requests receive dedicated resources with minimal contention for maximum precision, while lower-priority requests share resources for maintained throughput. This local quality differentiation allows the system to optimize precision where needed while maintaining overall throughput, resolving the contradiction between the two metrics.

Inventive Principle:
Principle #3Local quality
