Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for deploying and changing SIM cards in devices require physical access, leading to high labor costs and complex logistics, especially when it comes to managing multiple SIM cards and reducing tariff costs.
Innovation Solution
A system and method for a cellular router to communicate between a wireless communication module and a subscriber identity module (SIM) using modified requests and replies, allowing for remote SIM management without physical access, and optimizing SIM card usage to minimize labor and tariff costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical access is required to deploy and change SIM cards, then SIM card management can be performed, but labor costs and logistics complexity increase significantly
Solution Approach 1:
The patent replaces the mechanical/physical system of SIM card deployment with an electronic communication system. The wireless communication module establishes a data connection through the cellular network to the remote SIM, allowing deployment, configuration, and management operations to be performed remotely via data commands rather than physical access. This substitution eliminates the need for technicians to physically access devices and manually install SIM cards, thereby reducing labor costs and logistics complexity while maintaining full SIM card management functionality
Solution Approach 2:
The patent introduces a cellular network as an intermediary between the deployment system and the remote SIM card. The wireless communication module uses the cellular network infrastructure (base stations, core network) to transmit deployment commands and SIM card data to the remote location. This intermediary enables remote SIM card management by mediating the communication between the controlling system and the target SIM card without requiring direct physical access to the device housing the SIM card
2Adaptability or versatility
If multiple SIM cards are managed manually, then different tariff options can be selected, but the complexity of choosing and switching SIM cards increases
Solution Approach 1:
The patent enables the system to automatically manage multiple SIM cards without requiring manual intervention for selection and switching. The wireless communication module can autonomously establish data connections through the cellular network, retrieve available SIM card options, and select appropriate SIM cards based on predefined criteria or real-time network conditions. This self-service capability allows the system to handle multiple SIM cards with different tariff options automatically, reducing the complexity of SIM card management while maintaining flexibility in selecting the most suitable SIM card for each situation

AI summary
The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first modified request.
