Solution Overview

Problem

In non-cellular communications systems, a large quantity of channel resources are occupied when a logic entity (LE) sends tracking configuration information to all transmission points (TPs) managed by it, which is inefficient and can lead to reduced location tracking accuracy if UEs move out of adjacent coverage areas.

Innovation Solution

The method involves grouping transmission devices into a tracking set based on the UE's accessed device and movement attribute, where tracking configuration information is sent only to devices within the tracking set, optimizing channel resource usage and ensuring accurate location tracking by maintaining adjacent coverage areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the LE sends tracking configuration information to all TPs managed by the LE, then all TPs can potentially track UE location, but a relatively large quantity of channel resources are occupied

Engineering Contradiction:
Improvelocation tracking accuracyVSAvoidchannel resources
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent divides all TPs into multiple tracking sets, where each tracking set contains a subset of TPs. The LE sends tracking configuration information to only one tracking set at a time, rather than to all TPs simultaneously. This segmentation reduces the number of TPs receiving tracking configuration information at any given moment, thereby reducing channel resource occupation while maintaining location tracking capability through sequential coverage of all TPs across multiple tracking sets.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If the LE sends tracking configuration information to a subset of TPs to save channel resources, then channel resources are saved, but location tracking accuracy may deteriorate if UE moves out of the current tracking set coverage

Engineering Contradiction:
Improvechannel resourcesVSAvoidlocation tracking accuracy
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent implements dynamic switching between multiple tracking sets. When the LE determines that a UE has moved out of the coverage area of the current tracking set, it switches to a different tracking set that covers the UE's new location. This dynamic adjustment ensures that tracking configuration information is always sent to the appropriate set of TPs that can currently track the UE, maintaining location tracking accuracy while minimizing channel resource usage by only activating relevant tracking sets.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If tracking configuration information is sent to fewer TPs, then channel resources are saved, but the complexity of managing multiple tracking sets increases

Engineering Contradiction:
Improvechannel resourcesVSAvoidtracking set management
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent enables TPs to autonomously determine whether they belong to the currently active tracking set based on their identifiers and the tracking set configuration information received from the LE. Each TP can self-identify its membership in tracking sets without requiring complex centralized management for every switching decision. This self-service mechanism reduces the management burden on the LE while still enabling efficient tracking set switching and resource allocation.

Inventive Principle:
Principle #25Self-service
