Solution Overview

Problem

Multi-SIM mobile phones experience high energy consumption and resource preemption issues due to lack of unified regulation standards, leading to varying UE behaviors and inefficient resource management among multiple SIMs.

Innovation Solution

A method for information transmission where UEs report SIM capability information to base stations, enabling optimal resource scheduling and reducing conflicts by allowing coordinated SIM management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each SIM communicates with the network independently without cooperation, then each SIM can maintain its own connection, but energy consumption increases and resource preemption occurs

Engineering Contradiction:

Improveconnection stabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent combines multiple SIM communications into a unified resource management framework where the base station coordinates resource allocation across all SIMs. By merging the independent communication channels under centralized control, the system maintains connection reliability while eliminating redundant resource allocation and reducing overall energy consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The base station implements a universal resource pool that serves multiple SIMs simultaneously, allowing resources to be dynamically allocated based on demand. This multi-functional approach enables the same physical resources to be shared across different SIM connections, reducing total resource requirements and energy consumption while maintaining reliable connections for all SIMs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If each SIM communicates independently, then each SIM can be managed separately, but resource preemption and inefficient allocation occur

Engineering Contradiction:

Improveindependent management flexibilityVSAvoidresource allocation efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system implements feedback mechanisms where the base station continuously monitors resource usage and connection status of all SIMs, then dynamically adjusts resource allocation. This feedback loop enables the system to respond to changing conditions in real-time, optimizing resource allocation efficiency while maintaining the flexibility to manage each SIM's specific requirements.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The resource allocation system transitions from static independent management to dynamic coordinated management. The base station continuously adapts resource distribution based on current network conditions, SIM priorities, and usage patterns, enabling both flexible individual management and efficient overall resource utilization through dynamic adjustment.

Inventive Principle:

Principle #15Dynamics
