Solution Overview

Problem

Conventional mobility management methods are inadequate for zero power devices due to their capacity limitations, especially in scenarios requiring high-density and large-scale deployment.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional mobility management modes are used, then existing terminal devices can be managed, but zero power devices cannot meet deployment requirements due to capacity limitations

Engineering Contradiction:

Improveadaptability to zero power devicesVSAvoidmobility management capability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent inverts the conventional mobility management approach by having the network side initiate measurements and control handovers rather than relying on terminal device capabilities. The network device measures signals from AMP devices and autonomously determines handover actions, compensating for the limited capabilities of zero power devices.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces measurement signals as intermediaries that enable mobility management without requiring direct capability exchange between terminal devices and network. These signals allow the network to assess signal quality and control handovers indirectly, bridging the capability gap.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If zero power devices are deployed at high density, then large-scale deployment is achieved, but conventional mobility management cannot handle the capacity requirements

Engineering Contradiction:

Improvenumber of deployed devicesVSAvoidmobility management efficiency

Core Design Contradiction:

Quantity of substanceVSProductivity

Solution Approach 1:

The patent implements preliminary measurements of signal quality from multiple network devices before handover occurs. By measuring and evaluating signal characteristics in advance, the system prepares handover decisions ahead of time, enabling efficient management of high-density deployments without conventional methods.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent establishes a feedback mechanism where network devices continuously measure signal quality from AMP devices and adjust handover decisions based on these measurements. This closed-loop feedback enables dynamic adaptation to high-density scenarios, optimizing mobility management efficiency.

Inventive Principle:

Principle #23Feedback
