Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to implement a wireless personal communication protocol between an IC card and a second reader device without modifying the standard communication protocol between the IC card and a handset, limiting interconnection capabilities.
Innovation Solution
A method that enables a wireless personal communication protocol between an IC card and a second reader device by using a ZigBee communication protocol, which includes a processor and separate controllers for managing handset-IC card and wireless personal communication, allowing data processing and storage to avoid protocol modifications, and utilizing the ZigBeeEngine to parse and dispatch messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless personal communication protocol is integrated into an IC card alongside the standard handset-IC card communication protocol, then interconnection capability is enhanced, but device complexity increases
Solution Approach 1:
The patent divides the IC card into separate functional modules: a first controller for managing handset-IC card communication and a second controller for managing wireless personal communication. This segmentation allows each controller to operate independently, enhancing interconnection capability while managing device complexity through modular architecture.
Solution Approach 2:
The IC card is designed to support multiple communication protocols simultaneously through separate controllers, making it universally compatible with both traditional handsets and wireless personal area network devices. This multi-functionality enables the single device to interface with diverse communication systems without increasing overall complexity.
2Adaptability or versatility
If a wireless personal communication protocol is added to the IC card, then communication versatility is improved, but protocol interference may occur
Solution Approach 1:
By separating communication protocols into distinct controllers (first controller for handset communication, second controller for wireless personal communication), the patent prevents protocol interference while maintaining communication versatility. Each controller operates in its own namespace, eliminating conflicts.
Solution Approach 2:
The patent introduces a communication interface that acts as an intermediary between the two controllers and the external devices. This intermediary manages data flow and protocol coordination, ensuring reliable communication while supporting multiple protocols simultaneously.

AI summary
A method is for implementing a wireless personal communication protocol between an integrated circuit (IC) card and a reader device. The IC card is hosted in and in communication with a handset through a corresponding handset-IC card communication protocol. The method includes the handset transmitting an Application Protocol Data Unit (APDU) command to the IC card, according to the handset-IC card communication protocol, the IC card detecting an association between the APDU command and an applet stored inside the IC card, the IC card executing the APDU command, and the IC card executing the applet if an association between the APDU command and the applet is detected. The IC card detects data associated to a wireless personal communication with the reader device after the processing of the APDU command.
