Solution Overview

Problem

Existing methods for implementing Multi Subscriber Identity Module (MUSIM) gaps in complex network scenarios such as carrier aggregation and dual connectivity are inefficient, failing to effectively manage resource conflicts and signal sharing among multiple USIMs in MUSIM User Equipment (UE).

Innovation Solution

The method involves calculating and requesting MUSIM gaps based on timing configurations of the primary cell, including System Frame Number (SFN) and subframe numbers, to manage resource conflicts and signal sharing among multiple USIMs in MUSIM UEs, particularly in carrier aggregation and dual connectivity scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If MUSIM gaps are implemented in complex network scenarios (carrier aggregation and dual connectivity), then network operations and resource utilization are optimized, but the complexity of timing configuration and coordination increases

Engineering Contradiction:
Improvenetwork operations efficiencyVSAvoidtiming configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the timing configuration into separate components: primary cell timing configuration and secondary cell timing configuration. Each cell group has its own timing parameters (system frame number, subframe number, gap length) that can be independently configured and managed, reducing the overall complexity of coordinating multiple USIMs across carrier aggregation and dual connectivity scenarios.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic timing adjustment where the gap length and timing parameters can be modified based on current network conditions and USIM operational requirements. The system can dynamically allocate timing resources between multiple USIMs in carrier aggregation and dual connectivity modes, optimizing performance while adapting to changing network demands.

Inventive Principle:
Principle #15Dynamics

2Reliability

If timing configuration is aligned across multiple cells for MUSIM gap implementation, then resource conflicts are reduced, but the complexity of coordinating timing across carrier aggregation and dual connectivity increases

Engineering Contradiction:
Improveresource conflict reductionVSAvoidcoordination complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides timing coordination into separate cell group configurations, where each cell group (primary cell and secondary cell) has its own timing parameters. This segmentation allows independent timing control for each cell group, reducing conflicts between USIMs while avoiding the complexity of unified timing coordination across all cells.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a gap length parameter as an intermediary mechanism that mediates timing conflicts between multiple USIMs. By configuring appropriate gap lengths between USIM operations in carrier aggregation and dual connectivity modes, the system coordinates timing without requiring complex centralized control, thus reducing overall coordination complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
