Solution Overview

Problem

In multi-SIM devices, the common RF circuitry leads to inefficient resource sharing among SIMs, resulting in power and resource inefficiencies, data loss, and unreliable network operations due to the challenges of coordinating gaps for resource allocation among multiple SIMs with different activities and priorities.

Innovation Solution

A method and system for gap configuration in a wireless network that allows User Equipment (UE) to request and manage gaps in RF resource allocation among SIMs, enabling coordinated switching between network operators based on specific activities and services, using gap configuration requests and responses through RRC signaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If autonomous gaps are taken by UE for multi-SIM operations, then connectivity and service availability on multiple networks is improved, but service packet loss occurs on the serving network and resource efficiency deteriorates

Engineering Contradiction:
Improvemulti-SIM connectivityVSAvoidservice packet loss
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The UE sends a gap request message to the serving network before taking gaps for other SIM operations. This preliminary notification allows the network to prepare for potential packet loss and adjust scheduling, resolving the contradiction by maintaining reliability awareness while enabling multi-SIM adaptability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The network responds to gap requests with gap configuration messages that provide feedback on approved gap patterns. This feedback mechanism allows the network to control gap timing and duration, preventing excessive packet loss while still allowing multi-SIM operations to proceed

Inventive Principle:
Principle #23Feedback

2Device complexity

If multiple SIMs share common RF circuitry, then device cost and complexity are reduced, but resource allocation efficiency and power consumption worsen due to arbitration challenges

Engineering Contradiction:
ImproveRF circuitry integrationVSAvoidresource allocation efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The gap configuration mechanism dynamically adjusts gap timing and duration based on network conditions and SIM priorities. The network can modify gap patterns in response to changing service requirements, optimizing resource allocation efficiency while maintaining the cost-effective shared RF architecture

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters (gap start time, duration, periodicity) to optimize resource sharing among multiple SIMs. By adjusting these parameters based on service priorities and network conditions, the system maintains high resource allocation efficiency despite the simplified shared hardware architecture

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If gap duration is increased to accommodate other SIM activities, then multi-SIM operation capability is improved, but service performance and data transmission on the serving network deteriorate

Engineering Contradiction:
Improvemulti-SIM operation capabilityVSAvoidservice performance
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The UE requests only the minimum necessary gap duration required for other SIM activities, not excessive gaps. This partial action approach ensures that gaps are long enough to complete essential multi-SIM operations while minimizing impact on serving network performance and data transmission

Inventive Principle:
Principle #16Partial or excessive action
