Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional dual SIM devices can only use one SIM for packet service at a time due to limitations in radio resources and high-level operating systems, leading to inefficiencies and potential packet loss or delays when switching between SIMs.

Innovation Solution

An electronic device method for determining and selecting a primary and secondary data subscription based on a data subscription policy, establishing data connections through either subscription, and aggregating them based on conditions such as user preferences or throughput, allowing for simultaneous use of multiple SIMs for improved performance and data recovery in case of service failure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If only one SIM is used for packet service at a time, then device complexity is reduced, but data throughput and service reliability deteriorate

Engineering Contradiction:

Improveradio resource management complexityVSAvoiddata throughput

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent segments packet service data connections into multiple independent connections, each associated with a different SIM card. This allows the system to establish separate data connections for each SIM rather than sharing a single connection, thereby improving data throughput while managing complexity through structured segmentation of connection resources.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent merges multiple data connections from different SIM cards into a unified packet service framework. By combining the capabilities of multiple SIMs within a single service management architecture, the system achieves improved data throughput and reliability while maintaining manageable device complexity through integrated control.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If switching between SIMs is performed, then data subscription flexibility is improved, but packet loss and service delays increase

Engineering Contradiction:

Improvedata subscription flexibilityVSAvoidpacket delivery reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent establishes preliminary data connections for multiple SIM cards in advance, allowing the system to switch between SIMs without interrupting ongoing packet services. This preliminary connection setup enables seamless transitions and maintains packet delivery reliability while preserving subscription flexibility.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent ensures continuous packet service by maintaining active data connections across multiple SIM cards simultaneously. When switching between SIMs is required, the system can continue packet transmission without interruption, thereby preserving both subscription flexibility and packet delivery reliability.

Inventive Principle:

Principle #20Continuity of useful action

3Productivity

If multiple SIMs are used simultaneously for packet service, then data throughput and service reliability are improved, but device complexity increases

Engineering Contradiction:

Improvedata throughputVSAvoiddata connection management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a universal packet service management framework that handles multiple SIM cards through a unified architecture. This multi-functional system manages data connections from different SIMs using common control mechanisms, thereby improving data throughput while controlling device complexity through standardized management procedures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If data connections are established through multiple subscriptions, then service reliability is improved, but aggregation conditions and policy management complexity increase

Engineering Contradiction:

Improveservice continuity reliabilityVSAvoidaggregation policy management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs parameter-based aggregation conditions that automatically determine how data connections from multiple SIMs are combined. By using configurable parameters such as throughput thresholds and connection priorities, the system achieves improved service reliability while simplifying policy management through parameter-driven decision-making rather than complex rule-based control.
