Solution Overview

Problem

Current mobile communication apparatuses face challenges in simultaneously using multiple SIM cards without interrupting existing connections, as they require frequent signal reception quality measurements that interfere with data transmission and increase bandwidth usage, especially when stationary.

Innovation Solution

A mobile communication apparatus that includes a receiver and an ascertainment device to determine if it is stationary, allowing it to minimize signal reception quality measurements for secondary SIM cards, thus reducing connection interruptions and maintaining interference-free communication for primary SIM cards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If signal reception quality measurements are performed for secondary SIM cards, then network optimization and handover decisions are improved, but data transmission interruptions and bandwidth usage increase

Engineering Contradiction:
Improvenetwork optimizationVSAvoiddata transmission continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts measurement behavior based on device movement state. When the device is detected as stationary, measurement operations are suppressed or reduced for secondary SIM cards, allowing continuous data transmission for primary SIM cards without interruption. This dynamic adaptation resolves the contradiction by making the measurement process flexible rather than rigid.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the measurement parameter frequency based on movement detection. By detecting whether the device is stationary or moving, the system adjusts the measurement interval and intensity accordingly. For stationary devices, measurements are performed less frequently or not at all for secondary SIM cards, thereby maintaining data transmission continuity while still ensuring network optimization when needed.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If frequent signal reception quality measurements are performed, then handover decisions are optimized, but connection interruptions and bandwidth consumption increase

Engineering Contradiction:
Improvehandover decision accuracyVSAvoidbandwidth consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

Instead of continuous or frequent periodic measurements, the system implements event-driven periodic action where measurements are triggered only by specific conditions (device movement detection). This transforms the measurement process from time-based periodicity to condition-based periodicity, reducing unnecessary measurements and associated bandwidth consumption while maintaining handover decision accuracy when movement occurs.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses the primary SIM card's measurement results and movement detection to serve the secondary SIM card's needs. By leveraging the existing measurement infrastructure and results from the active primary connection, the system avoids duplicating measurement efforts for secondary SIM cards, thereby reducing overall bandwidth consumption while still achieving reliable handover decisions.

Inventive Principle:
Principle #25Self-service

3Reliability

If measurements are performed for one SIM card, then network optimization is achieved, but data reception for other SIM cards is interrupted

Engineering Contradiction:
Improvenetwork optimizationVSAvoidsimultaneous multi-SIM operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system segments the measurement process by SIM card and by movement state. Different measurement strategies are applied to different SIM cards based on their operational state. For stationary devices, measurements are segmented and suppressed for secondary SIM cards while continuing for primary SIM cards. This segmentation allows independent optimization of each SIM card's performance without forcing interruptions to all active connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary measurement results sharing and configuration setup before actual measurement execution. By pre-configuring measurement parameters and results sharing mechanisms, the system prepares the infrastructure to handle multi-SIM operations efficiently, allowing measurements to be performed on one SIM card without automatically interrupting data reception for other SIM cards.

Inventive Principle:
Principle #10Preliminary action

AI summary

A mobile communication apparatus is provided, which may have a receiver, and may ascertain whether a movement of the apparatus is below a prescribed limit and on that basis may prompt the receiver of the mobile communication apparatus to perform a signal reception quality measurement. A mobile communication apparatus is also provided, which may have a transmission/reception device, and may ascertain whether a movement of the apparatus is below a prescribed limit based on a set of radio cells in a mobile radio communication that is active, a radio cell that serves the mobile communication apparatus, or a set of adjacent radio cells that is configured for the mobile communication apparatus.
