Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to facilitate large-scale network testing on production lines without frequent physical SIM card switching, which is difficult due to limitations in terminal support for physical or embedded SIMs, leading to waste and increased costs.
Innovation Solution
A SoftSIM-based testing method that involves receiving and activating SoftSIMs, predicting and managing traffic values, and dynamically allocating SoftSIMs and traffic across testing terminals through a SoftSIM cloud server, enabling efficient real-network testing and recycling of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical SIM cards are used for network testing on production lines, then network testing can be performed, but frequent SIM card switching is required which increases time consumption and operational complexity
Solution Approach 1:
The patent creates a virtual copy of the SIM card functionality through SoftSIM technology. Instead of using physical SIM cards that need to be manually switched, the system generates software-based SIM identities that can be rapidly provisioned and deactivated. The SoftSIM cloud server generates virtual SIM card information (including ICCID, IMSI, and authentication keys) that replicates the functionality of physical SIM cards, enabling automated network testing without physical card handling.
Solution Approach 2:
The patent replaces the mechanical system of physical SIM card insertion and switching with a software-based system. The SoftSIM technology substitutes the physical card mechanism with virtual SIM card generation and management through software. The testing terminal communicates with the SoftSIM cloud server to obtain virtual SIM credentials, eliminating the need for mechanical SIM card handling operations.
2Reliability
If physical SIM cards are used for network testing, then network access is enabled, but the cost increases due to waste of physical SIM cards when terminals do not support them
Solution Approach 1:
The patent changes the fundamental parameter of SIM card existence from physical to virtual. Instead of dealing with physical SIM cards that have fixed attributes, the system generates virtual SIM card parameters dynamically through software. The SoftSIM cloud server can generate unlimited virtual SIM identities with customizable parameters (ICCID, IMSI, authentication keys) that can be created, modified, and deleted without any physical material consumption.
Solution Approach 2:
The patent creates virtual copies of SIM card functionality without requiring physical substrates. The SoftSIM technology generates software-based SIM identities that replicate all necessary network access functions, eliminating the need for physical SIM card materials. This virtual copying approach allows unlimited proliferation of SIM identities without any material waste.
3Loss of substance
If SoftSIM is used for network testing, then the need for physical SIM cards is reduced, but traffic management and allocation become more complex
Solution Approach 1:
The patent introduces the SoftSIM cloud server as an intermediary between the testing terminals and the network. This intermediary manages all virtual SIM card generation, activation, and traffic allocation centrally. The cloud server acts as a mediator that handles the complexity of traffic management by providing automated workflows for traffic value prediction, SoftSIM generation, and resource allocation, thereby simplifying the overall system architecture despite the added virtualization layer.
Solution Approach 2:
The patent implements feedback mechanisms where the testing terminal predicts the traffic value required for testing, and this prediction is fed back to the SoftSIM cloud server. The server uses this feedback to generate an appropriate number of virtual SIM cards and allocate traffic resources dynamically. This closed-loop feedback system automates traffic management, reducing manual intervention while optimizing resource allocation based on actual testing needs.

AI summary
A testing method, device and/or system based on a Soft Subscriber Identity Module (SoftSIM) are provided. The testing method based on a SoftSIM including receiving a SoftSIM and a testing traffic value transmitted by a SoftSIM cloud server, importing and activating the received SoftSIM and completing registration in a network, and performing a real-network testing based on the SoftSIM and the received testing traffic value may be provided. According to the testing method, automatic real-network testing of a production line can be achieved by using limited SoftSIM resources and traffic to avoid frequent insertion of physical SIM cards on the production line, and the cost of a large number of physical SIM cards is saved and testing is facilitated by using flexible SoftSIM configurations. The use of dynamically configurable SoftSIM communication avoids wasting the communication cost of individual physical SIM cards.
