Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a terminal uses a single SIM to communicate with a base station, then communication connection is stable, but the terminal cannot simultaneously communicate with multiple base stations using multiple SIMs

Engineering Contradiction:

Improvemulti-SIM communication capabilityVSAvoidcommunication connection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The terminal divides communication resources by creating separate communication contexts for each SIM card, with dedicated configuration information (first communication configuration information and second communication configuration information) for each SIM-base station pair, allowing independent management of multiple communication connections

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The terminal dynamically switches between different communication configurations based on which SIM is actively communicating, adjusting the communication state of each SIM according to real-time needs while maintaining the ability to quickly transition between single-SIM and multi-SIM modes

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the terminal switches between SIMs to communicate with different base stations, then multi-base station communication is enabled, but existing communication connections are interrupted

Engineering Contradiction:

Improvemulti-base station communicationVSAvoidcommunication connection continuity

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The terminal pre-configures communication parameters and maintains dormant communication contexts for non-active SIMs, so when a SIM needs to communicate, the transition can occur without establishing new connections from scratch, thereby avoiding interruption of existing communications

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal maintains continuous communication capability by keeping multiple SIMs in a ready state with pre-configured parameters, allowing seamless switching between SIMs without breaking the communication flow, ensuring that at least one SIM is always actively communicating with its base station

Inventive Principle:

Principle #20Continuity of useful action

3Productivity

If the terminal maintains single SIM communication mode, then communication efficiency is high, but the terminal cannot utilize multiple SIMs for simultaneous communication

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidmulti-SIM simultaneous communication

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The terminal applies different communication strategies to different SIMs based on their individual needs and configurations, with each SIM having its own optimized communication parameters and base station associations, allowing each SIM to operate at peak efficiency while contributing to overall multi-SIM communication capability

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The terminal's communication module is designed to handle multiple SIMs with a unified management framework that can adapt to single-SIM or multi-SIM scenarios, providing a universal communication interface that maintains high efficiency whether one or multiple SIMs are actively communicating

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Provided are time segment request methods, time segment configuration methods, electronic devices and computer readable storage media, the time segment request method includes: receiving time segment configuration information from a network side device; in response to determining that the second SIM is to communicate with a second base station during communication between a first SIM and a first base station, controlling the first SIM to communicate with the first base station and controlling the second SIM to communicate with the second base station based on the time segment configuration information. It is not necessary to completely interrupt a communication connection between the first SIM and the first base station in order to communicate with the second base station via the second SIM, which is conducive to improving communication efficiency of the terminal.
