Smart Card Web Server Gateway for Bulk Data Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SIM card technologies, such as Over The Air (OTA), are limited in interacting with large data files due to low data carrying capacity, and lack methods for remote management, data update, and configuration of mobile phone contents, especially with the increasing capacity of SIM cards.
Innovation Solution
A method and system utilizing a Smart Card Web Server (SCWS) that enables a mobile phone to act as a gateway between the SIM card and a remote management server, establishing session and data channels for bulk data updates, security authentication, and customizable access policies through HTTP/HTTPS protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If OTA technology is used for SIM card remote operations, then remote service delivery is enabled, but data carrying capacity is limited to small text information
Solution Approach 1:
The patent introduces a mobile phone as an intermediary device between the SIM card and the remote server. The mobile phone's TCP/IP protocol stack acts as a mediator that enables the SIM card to access high-capacity data channels through the mobile phone's communication capabilities, thereby overcoming the limited data carrying capacity of traditional OTA technology while maintaining backward compatibility
Solution Approach 2:
The patent makes the mobile phone serve multiple functions: it acts as a gateway for data transmission, provides TCP/IP protocol stacking capabilities, and enables both traditional OTA services and new high-capacity data services through a single device, thereby increasing adaptability without requiring separate systems for different service types
2Quantity of substance
If SIM card capacity increases to store large files, then storage capability is improved, but remote interaction methods become insufficient
Solution Approach 1:
The mobile phone serves as an intermediary that bridges the gap between the SIM card's large storage capacity and the need for remote management. It provides the communication protocols and data transmission capabilities needed to remotely access and manage the expanded storage capacity, making large file operations feasible through standard mobile phone interfaces
Solution Approach 2:
The patent transitions from the traditional SIM card-to-server direct communication model to a three-dimensional architecture involving SIM card-mobile phone-server interactions. This dimensional change enables remote management of large files by utilizing the mobile phone's advanced communication capabilities as an intermediate layer
3Reliability
If mobile phone acts as gateway with TCP/IP protocol stack, then secure data transmission is enabled, but system complexity increases
Solution Approach 1:
The mobile phone's existing TCP/IP protocol stack and security mechanisms are leveraged to provide secure data transmission without requiring additional dedicated security hardware or complex cryptographic systems in the SIM card. The mobile phone's built-in security capabilities serve the entire system, reducing overall complexity while maintaining high security standards

AI summary
Disclosed are a method and system for implementing a smart card remote operation based on a smart card web server. As a mobile phone is prompted to start update by a short message transmitted thereto, the problem of paging the mobile phone is solved. A remote network is accessed by using a TCP/IP protocol stack, so data chunks are updated conveniently and reliably. The mobile phone is used as a gateway to connect a smart card and a remote management server, thereby realizing security identity authentication and data integrality verification, implementing data encryption and customizable access policies, and increasing the demand of an operator for enhancing value-added services of the smart card.
