Telecommunication Terminal Authorization Transfer via Segmented NFC and Wireless Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NFC-based telecommunications systems lack the capability to transmit authorization information or authorizations between terminals over distances exceeding the range of the NFC interface, limiting the use of services and applications across distant devices.
Innovation Solution
A method that utilizes a combination of NFC and wireless interfaces, such as WLAN or Bluetooth, to transmit authorization information or authorizations from one telecommunications terminal to another, even when they are several meters or kilometers apart, ensuring secure and reliable communication through secure elements like SE, UICC, or microSD cards, and allowing for 'peer-2-peer', 'client-server', or server-mediated transmission modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC interface is used for transmission, then security level is maintained, but transmission distance is limited to close range
Solution Approach 1:
The transmission process is divided into two segments: first, NFC interface is used for secure authorization verification at close range; second, wireless interface is used for data transmission over extended distance. This segmentation allows the system to maintain security through NFC while achieving long-distance transmission through wireless communication.
Solution Approach 2:
A server device acts as an intermediary that receives authorization information from the first terminal via NFC, verifies it, and then enables the second terminal to access the service. The server mediates between the two terminals, allowing secure authorization through NFC while enabling extended distance communication through wireless interfaces.
2Adaptability or versatility
If authorization information is transmitted over extended distance, then accessibility is improved, but security risks increase
Solution Approach 1:
The system segments the transmission process into secure authorization (NFC) and data communication (wireless) phases. By separating these functions, the patent maintains security for authorization while enabling accessibility for data transmission over extended distances.
Solution Approach 2:
The system performs preliminary authorization verification through NFC interface before allowing any data transmission. This preliminary action ensures that only authenticated users can access services, mitigating security risks during subsequent wireless transmission over extended distances.
3Speed
If NFC interface is used for direct transmission, then transmission speed is fast, but transmission range is limited
Solution Approach 1:
The transmission process is segmented into authorization phase (NFC, fast but short-range) and data transmission phase (wireless, long-range). This allows the system to leverage the speed advantage of NFC for authorization while using wireless interfaces for extended distance data communication.
Solution Approach 2:
The system transitions from two-dimensional close-range NFC communication to three-dimensional wireless communication space, enabling transmission over extended distances while maintaining security through the preliminary NFC authorization layer.

AI summary
The method involves storing authorization information in a memory area (11) of a telecommunication terminal (10), and storing the information in a memory area (21) of another telecommunication terminal (20). Wireless interfaces are formed adjacent to a near field communication (NFC) interface for transmitting the information from the former terminal to the latter terminal. The terminals are arranged at a distance to each other during the transmission of the information or authorization, where the distance exceeds the range of the NFC interface. Independent claims are also included for the following: (1) a telecommunication terminal (2) a system with telecommunication terminals (3) a computer program with program code medium for executing a method for transferring authorization information or authorization (4) a computer program product with a computer readable medium for executing a method for transferring authorization information or authorization.
