Solution Overview

Problem

Conventional multi-SIM wireless communication devices struggle to maintain multiple wireless connections simultaneously due to RF resource sharing, leading to inconvenience as they often suspend or refuse new connections when existing communications are active.

Innovation Solution

A method and device that determine a target SIM to handle multiple wireless communications by transferring connections, allowing simultaneous maintenance of calls through either the first or second SIM, ensuring continuous communication without suspension.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a first SIM occupies RF resources to perform wireless communication with a first terminal device, then the first wireless communication is maintained, but the device cannot establish a new wireless communication through a second SIM

Engineering Contradiction:

Improvewireless communication connectionVSAvoidmulti-SIM parallel connection capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent merges multiple wireless communications that were originally assigned to different SIMs into a single target SIM. When a second wireless communication request arrives while the first SIM is occupied, the system transfers the first communication to the second SIM and establishes the second communication on the second SIM, allowing both communications to coexist on the same RF resources through the second SIM.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic SIM selection and communication transfer mechanisms. The system continuously monitors RF resource availability and dynamically determines which SIM should handle which communication based on current resource status, enabling flexible adaptation between single-SIM and multi-SIM operation modes.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the device ends existing wireless communication to accommodate a new connection request, then the new wireless communication can be established, but the existing communication is interrupted

Engineering Contradiction:

Improvenew connection establishmentVSAvoidexisting communication continuity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent performs preliminary actions by proactively transferring the first wireless communication to the second SIM before the second communication request is fully processed. This preliminary transfer ensures that when the second communication is established, the first communication is already secured on the second SIM, preventing any interruption or loss of the first communication.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the device refuses new connection requests during active communication, then existing communication stability is maintained, but user convenience and communication efficiency deteriorate

Engineering Contradiction:

Improvecommunication stabilityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent makes a single SIM (the target SIM) universal by enabling it to handle multiple wireless communications simultaneously. The second SIM serves both as the active communication channel for the first call and as the new channel for the second call, eliminating the need to refuse new connections while maintaining stability through controlled transfer mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method of performing wireless communication for a wireless communication device including a first Subscriber Identity Module (SIM) and a second SIM includes performing a first wireless communication with a first terminal device through the first SIM, receiving a request for connection of a second wireless communication from a second terminal device through the second SIM, determining a target SIM among the first SIM and the second SIM in response to the request, and performing the first wireless communication and the second wireless communication through the target SIM.
