Soft SIM Card Network Connection Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network connection methods require a permanently resident seed hard card for Internet access, leading to high costs for users as they need to continuously pay for the card to maintain connectivity.
Innovation Solution
A method utilizing activation soft SIM cards shared among multiple devices to establish a network connection, where a seed soft SIM card and cloud SIM card are acquired through requests to a server, allowing Internet access without the need for a physical card, and enabling cost reduction by efficient resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resident seed hard card is permanently arranged in the communication device to enable Internet access, then the device can establish communication with the server and surf the Internet, but the cost of Internet surfing becomes high due to permanent payment requirements
Solution Approach 1:
The patent replaces the physical hard card with a soft SIM card that exists as digital data in the terminal device. This copying approach eliminates the need for permanent physical card possession while maintaining network access functionality, thereby reducing user costs without compromising connectivity reliability
Solution Approach 2:
The soft SIM card can be shared across multiple terminal devices, allowing one soft SIM card to serve multiple functions and users. This multi-functionality reduces the need for each user to maintain separate permanent card subscriptions, thereby lowering overall Internet surfing costs while ensuring reliable access for each device
2Ease of operation
If a resident seed hard card is permanently arranged in the communication device, then authentication with the server can be performed, but the device complexity increases due to the requirement of permanent card presence
Solution Approach 1:
The patent replaces the mechanical physical hard card system with a software-based soft SIM card system. This substitution eliminates the need for physical card insertion, removal, and management operations, thereby simplifying the authentication process while reducing device complexity related to card handling mechanisms
3Loss of energy
If activation soft SIM cards are shared among multiple terminal devices, then the cost of Internet surfing is reduced and resource utilization is improved, but the reliability of network connection may be affected
Solution Approach 1:
The patent ensures that when a soft SIM card is shared among multiple devices, each device can maintain continuous network access by establishing mobile networks independently. The system maintains continuous useful action by allowing simultaneous or sequential activation without interrupting service, thereby preserving connection reliability while enabling cost-effective sharing

AI summary
The present disclosure provides a network connection method, including: establishing a first mobile network through one activation soft SIM card in at least one activation soft SIM card previously arranged in a first terminal device in response to receiving a network connection request; transmitting a seed soft SIM card acquisition request to the server; receiving seed soft SIM card information which corresponds to the seed soft SIM card acquisition request and is returned by the server, and establishing a second mobile network to enable the first terminal device to be in communication connection with the server; transmitting a cloud SIM card acquisition request to the server; and receiving cloud SIM card information which corresponds to the cloud SIM card acquisition request and is returned by the server, and establishing a third mobile network to enable the first terminal device to be connected to the network through the third mobile network.
