RFID Service Ordering for Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing services to mobile users are costly, error-prone, and insecure, with limitations on code length, dependency on specific networks, and vulnerability to code duplication and address changes.
Innovation Solution
A method using RFID technology to read and transmit electronic codes to a server, which connects to a name service-server to retrieve the corresponding electronic address for service access, allowing for dynamic address changes and secure, universal service ordering across networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual code entry is used for service ordering, then code length can be optimized for security, but entry accuracy deteriorates and errors increase
Solution Approach 1:
The patent uses RFID technology to automatically copy the code from the value card to the mobile device without manual entry. The RFID reader in the mobile device automatically reads the code stored in the RFID tag on the value card, eliminating manual typing and associated errors while maintaining security through automatic one-time code retrieval.
2Ease of operation
If barcode readers are built into portable devices, then code reading becomes automated, but device complexity and cost increase
Solution Approach 1:
The patent introduces an intermediary RFID reader component that can be integrated into mobile devices without requiring complex barcode reading capabilities. The RFID reader acts as a simple intermediary between the value card and the service ordering system, providing automated code retrieval with minimal device complexity compared to full barcode scanning systems.
3Ease of manufacture
If codes are printed on value cards for manual entry, then code distribution is simple, but code duplication and falsification become easier
Solution Approach 1:
The patent replaces the mechanical printing method with RFID technology. Instead of printing codes on value cards that can be easily copied, the codes are stored in RFID tags that can be read automatically. This substitution of the information storage mechanism maintains ease of distribution while significantly improving security against duplication and falsification.
4Ease of operation
If service ordering addresses are hardcoded on value cards, then ordering is straightforward, but address changes break existing codes
Solution Approach 1:
The patent implements dynamic address management where the service ordering address is not hardcoded on the value card but is retrieved dynamically from a central database. The RFID code on the value card serves as a key to access the current address in the database, allowing the system to adapt to address changes without invalidating existing value cards while maintaining simple ordering operations.

AI summary
Method for making services available to mobile users with the following method steps: the mobile subscriber reads an electronic code (100) stored in an RFID element (10) with an RFID reader device (2); said electronic code (100) is transmitted over a telecommunication network to a server (5); the server (5) transmits a query to a name service-server (6), wherein links between several electronic codes (100) and several electronic addresses are registered; the name service-server (6) sends the address of the page said above-mentioned page; the ordered service is supplied to the mobile user.
