Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face interference issues between different radio frequency interfaces, particularly Bluetooth and near-field communication technologies, leading to disrupted communication processes.
Innovation Solution
A method and device configuration that controls the activation and deactivation of multiple communication interfaces, including a time delay between deactivation of a first interface and activation of a second interface, to prevent interference, particularly by using a software development kit (SDK) to manage the transition between Bluetooth Low Energy (BLE) and near-field communication (NFC or RFID) interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first communication interface (radio frequency) is activated to communicate according to the first radio access technology, then communication via the first interface is enabled, but the proper functioning of the second interface (short-range link) is disrupted
Solution Approach 1:
The system performs preliminary action by receiving an information signal from a radio frequency beacon before activating the second interface. This advance detection allows the system to prepare for interface switching, ensuring that the first interface is deactivated before the second interface is activated, thereby preventing interference between the two communication interfaces.
Solution Approach 2:
The system implements dynamic control of communication interfaces by sequentially activating and deactivating interfaces based on received signals. The first interface is activated to receive the information signal, then deactivated, and subsequently the second interface is activated. This dynamic switching ensures that only one interface is active at a time, eliminating interference while maintaining communication reliability.
2Reliability
If a time delay is applied between deactivation of the first interface and activation of the second interface, then interference is prevented, but communication transition time is increased
Solution Approach 1:
The information signal from the radio frequency beacon acts as an intermediary that triggers the interface switching process. By using this signal as a mediator, the system can coordinate the deactivation of the first interface and activation of the second interface with a controlled time delay, ensuring stable communication transition while minimizing unnecessary time loss.
3Adaptability or versatility
If multiple communication interfaces are activated simultaneously, then communication versatility is improved, but communication interference increases
Solution Approach 1:
The system segments the communication process by dividing it into distinct phases: first interface activation and signal reception, first interface deactivation with time delay, and second interface activation. This segmentation ensures that each interface operates independently without interference, maintaining communication versatility while preventing harmful interactions between interfaces.

AI summary
The invention relates to data processing carried out by a terminal, for communication via a plurality of interfaces of the terminal, said terminal (TER) comprising at least: - a first interface for communication via a radiofrequency link (BJR), and - a second interface for communication via a short-range link (CP) which can be polluted by the radiofrequency link (BJR) via the first interface. The invention proposes configuring the terminal to: - activate the first interface, - deactivate the first interface and initiate a time-out during which the terminal can activate a third interface for communication via an optical link (INF), - and then activate the second interface.
