Solution Overview

Problem

Conventional Dual Subscriber Identity Module (SIM) Dual Standby (DSDS) techniques require manual network selection and lack dynamic network switching, leading to network interruptions and inefficient resource management, especially when coverage overlap is not guaranteed.

Innovation Solution

Implementing a system with multiple SIMs where a communication manager automatically selects and switches between networks for voice and data communications based on pre-programmed configuration settings, ensuring seamless offloading of data traffic to cost-effective networks while preserving battery life and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual network selection is used in conventional DSDS, then device complexity is reduced, but ease of operation deteriorates due to lack of dynamic network switching

Engineering Contradiction:

Improvenetwork switchingVSAvoidnetwork management

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically detecting available networks and selecting the most appropriate one based on pre-configured policies, eliminating the need for manual user intervention in network selection while maintaining operational simplicity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The network selection process transitions from static manual configuration to dynamic automatic selection, where the system continuously monitors network availability and switches between networks based on real-time conditions and pre-set policies

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If automatic network switching is implemented, then ease of operation improves, but device complexity increases due to additional management requirements

Engineering Contradiction:

Improvenetwork switchingVSAvoidcommunication manager

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary action by pre-configuring network policies and selection criteria before runtime, allowing the communication manager to execute automatic network switching based on predetermined rules rather than requiring complex real-time decision-making algorithms

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The communication manager acts as an intermediary layer between the hardware components and the user, abstracting the complexity of network management while providing simple automatic network selection functionality to the end user

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If multiple networks are monitored for coverage, then reliability improves, but use of energy increases due to continuous scanning

Engineering Contradiction:

Improvenetwork coverageVSAvoidbattery consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system applies partial action by monitoring only the necessary subset of networks based on pre-configured policies and current service requirements, rather than continuously scanning all available networks, thereby reducing energy consumption while maintaining adequate coverage

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Network monitoring is performed periodically rather than continuously, with the system checking network availability at scheduled intervals and switching networks based on accumulated information, reducing the energy burden of constant scanning

Inventive Principle:

Principle #19Periodic action

4Loss of time

If manual network designation is required, then device complexity is reduced, but loss of time increases due to user intervention

Engineering Contradiction:

Improvenetwork selection timeVSAvoidautomation system

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Inventive Principle:

Principle #10Preliminary action

AI summary

According to one configuration, a system comprising: a first SIM (Subscriber Identity Module) device; a second SIM device; and user equipment in which the first SIM device and the second SIM device are installed. The user equipment is operable to: access first subscriber identity information stored in the first SIM device, the first subscriber identity information providing the user equipment access to a first wireless network in a network environment; access second subscriber identity information stored in the second SIM device, the second subscriber identity information providing the user equipment access to a second wireless network in the network environment; and via analysis of configuration settings in the second subscriber identity information, detect that the second network is assigned to support non-voice wireless communications between the user equipment and a remote network.
