Solution Overview

Problem

In 5G network environments, existing technologies face inefficiencies and discontinuity in network data switching between SIM cards, requiring manual user intervention and complicating the process, which leads to low switching efficiency and unreliable continuity of network data connections.

Innovation Solution

A data switching method and apparatus that monitors network statuses of multiple SIM cards to establish dual standby and dual active network connections, allowing seamless switching between SIM cards by maintaining and switching data connections based on signal quality and service performance, thereby reducing switching time and improving efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual user intervention is used to switch SIM cards for network data, then user control is maintained, but switching efficiency is low and operation complexity increases

Engineering Contradiction:
Improveswitching efficiencyVSAvoidoperation complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system pre-establishes data connections for multiple SIM cards in advance, so when switching is needed, the connection is already prepared and ready to use immediately. This eliminates the need for manual intervention and reduces switching time, as the system has already performed the necessary connection setup beforehand.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal automatically monitors network statuses and performs SIM card switching based on pre-established connections without requiring user intervention. The system serves itself by detecting network conditions and autonomously completing the switching process, thereby improving efficiency and reducing operational complexity.

Inventive Principle:
Principle #25Self-service

2Reliability

If data connection is established during SIM card switching, then network data can be used, but switching time increases and continuity is interrupted

Engineering Contradiction:
Improvecontinuity of network dataVSAvoidswitching time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Data connections for multiple SIM cards are established in advance before switching occurs. This preliminary setup ensures that when a switch is needed, the new connection is already ready and can be activated immediately, eliminating interruptions and reducing switching time while maintaining continuous network data availability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous network data connectivity by having multiple data connections established simultaneously. During switching, the useful action of data transmission continues without interruption because the target connection is already prepared and ready to take over immediately from the current connection.

Inventive Principle:
Principle #20Continuity of useful action

3Speed

If multiple SIM cards maintain data connections simultaneously, then switching speed improves, but device complexity increases

Engineering Contradiction:
Improveswitching speedVSAvoidconnection management complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The terminal is designed with multi-functionality to handle multiple simultaneous data connections across different SIM cards. The system universally manages network statuses and connection states for multiple SIMs, enabling fast switching without requiring complex manual configuration, as the device is built to natively support multiple active connections.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system continuously monitors network statuses of multiple SIM cards and uses this feedback to automatically manage data connections. Based on real-time network condition feedback, the system intelligently determines which SIM card to switch to, simplifying connection management while maintaining multiple active connections for rapid switching capability.

Inventive Principle:
Principle #23Feedback

AI summary

A data switching method, applied to a terminal on which multiple SIM cards for user identification are installed, includes: monitoring network statuses of the multiple SIM cards, and determining that there is a SIM card satisfying a combination of dual standby and dual active network statuses among the multiple SIM cards based on the network statuses; establishing data connection for the SIM card satisfying the combination of dual standby and dual active network statuses in response to determining that there is the SIM card satisfying the combination of dual standby and dual active network statuses among the multiple SIM cards based on the network statuses; and disconnecting routing connection of a SIM card that currently establishes routing connection, and switching to a SIM card that has established data connection to establish routing connection in response to a need to switch the SIM card that currently establishes the routing connection.
