Mobile Terminal Smart Card Location Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack a defined interface for providing location information from GPS devices to smart cards, limiting the ability of smart cards to proactively request and obtain geographical location data.
Innovation Solution
A method and apparatus that enable a mobile terminal to communicate with a smart card and a GPS device, allowing the terminal to provide terminal profile information, receive location requests, obtain location data from the GPS device, and send this information as an envelope signal to the smart card, thereby establishing interfaces for smart cards to access location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a GPS device is connected to the mobile terminal, then location information can be obtained, but the smart card cannot proactively request or obtain this location information due to lack of defined interface
Solution Approach 1:
The mobile terminal acts as an intermediary between the GPS device and the smart card. It receives location information from the GPS device, processes it according to smart card interface standards, and forwards it to the smart card. This mediator approach allows communication between devices that would otherwise lack direct compatibility.
Solution Approach 2:
The mobile terminal is designed with multi-functionality, serving both as a GPS receiver and as a smart card interface adapter. It can simultaneously manage GPS data acquisition, process smart card commands, and translate between different communication protocols, making the system universally compatible without requiring separate dedicated devices.
2Adaptability or versatility
If the smart card is made to proactively request location information, then location services are enhanced, but the existing smart card interface standards must be extended or modified
Solution Approach 1:
The system dynamically adapts to different operational modes. The mobile terminal can operate in proactive mode (initiating location requests) or reactive mode (responding to smart card requests), and can switch between different data formats and communication protocols as needed, while maintaining compliance with existing smart card interface standards.
Solution Approach 2:
The mobile terminal changes operational parameters such as request initiation timing, data format selection, and communication protocol version based on the specific smart card type and service requirements. This allows the system to maintain standard compliance while providing enhanced location services through parameter adjustment rather than structural modification.

AI summary
A method and mobile terminal for communicating with a smart card. The method includes transmitting, to the smart card, terminal profile information; receiving, from the smart card, a geographical location request for acquiring a current geographical location based on the terminal profile information; and transmitting, to the smart card, a terminal response indicating whether the geographical location request has been successfully processed. The mobile terminal processes only one of multiple geographical location requests based on a receiving order, when the multiple geographical location requests are received from the smart card. When the geographical location request has not been successfully processed, the terminal response includes one of reason information among: first reason information indicating that acquiring the current geographical location is beyond capabilities of the mobile terminal, and second reason information indicating that the mobile terminal is currently unable to acquire the current geographical location.
