Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Paging collisions occur in multi-SIM terminals when different subscriber identity modules (SIMs) receive paging messages at the same time, leading to inefficiencies in communication systems.

Innovation Solution

A method and apparatus for a multi-SIM terminal to determine a target SIM and transmit information about paging collisions to a network-side device via that SIM, ensuring that only one network-side device receives the collision information and provides feedback to adjust paging occasions, thereby avoiding continuous collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all SIMs transmit paging collision information to their respective network-side devices, then each SIM can independently report the problem, but multiple network-side devices receive redundant information leading to unnecessary feedback and continuous collisions

Engineering Contradiction:

Improvepaging collision problem reporting reliabilityVSAvoidcommunication coordination complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent designates one SIM as a 'target SIM' that acts as an intermediary to consolidate and transmit paging collision information to a single network-side device. This mediator approach prevents multiple network-side devices from receiving redundant information, thereby eliminating unnecessary feedback loops while maintaining reliable problem reporting.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent merges multiple reporting channels into a single reporting path by selecting one target SIM to represent all SIMs involved in paging collisions. This consolidation combines the reporting function of multiple SIMs into one unified channel, reducing network-side device complexity and preventing redundant feedback.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If paging occasions of different SIMs overlap, then multi-SIM functionality is maintained, but paging collisions occur reducing communication efficiency

Engineering Contradiction:

Improvemulti-SIM functionalityVSAvoidcommunication efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent establishes a feedback mechanism where the target SIM transmits paging collision information to the network-side device, which then provides feedback to adjust paging occasions. This feedback loop enables the system to maintain multi-SIM functionality while improving communication efficiency by resolving overlaps through coordinated paging occasion adjustments.

Inventive Principle:

Principle #23Feedback

3Loss of information

If paging collision information is transmitted via multiple SIMs to different network-side devices, then comprehensive coverage is achieved, but redundant feedback increases time loss

Engineering Contradiction:

Improvepaging collision information coverageVSAvoidfeedback processing time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent extracts the information transmission function from multiple SIMs and concentrates it in a single target SIM. This extraction eliminates redundant information transmission paths and reduces feedback processing time while maintaining comprehensive coverage of paging collision information through the unified reporting channel.

Inventive Principle:

Principle #2Taking out (Extraction)
