Dual-Radio Terminal Control for Emergency Transmission Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face increased communication jamming and congestion when switching to an emergency mode, as continuous transmission in this mode interferes with normal communication operations.
Innovation Solution
A wireless communication terminal with dual communication units (first and second-type) that switches to a predetermined communication mode to temporarily stop continuous transmission upon receiving a connection request, allowing acknowledgment and establishment of a connection using a different communication method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication terminal switches to emergency mode and performs continuous transmission, then emergency notification capability is improved, but communication jamming and interference in normal operation increases
Solution Approach 1:
The patent implements periodic transmission in emergency mode instead of continuous transmission. The terminal transmits emergency notifications at predetermined intervals, which maintains the ability to alert other terminals while reducing the duration of channel occupation and minimizing interference with normal communication operations.
Solution Approach 2:
The patent dynamically adjusts transmission behavior based on communication state. When a connection request is received, the terminal temporarily suspends emergency mode transmission to prioritize establishing normal communication connections, thereby adapting transmission characteristics to current communication needs and reducing jamming.
2Reliability
If the wireless communication terminal performs continuous transmission in emergency mode, then emergency situation notification is ensured, but communication congestion increases
Solution Approach 1:
By transmitting emergency notifications periodically rather than continuously, the patent reduces the total time the communication channel is occupied, thereby decreasing congestion and improving the efficiency of normal communication operations while still ensuring emergency situations are notified.
Solution Approach 2:
The terminal dynamically prioritizes communication tasks by temporarily suspending emergency transmission when connection requests are received, allowing normal communication operations to proceed without congestion while maintaining emergency notification capability when the channel is available.
3Device complexity
If the wireless communication terminal uses the same communication frequency for both normal and emergency mode, then device complexity is reduced, but communication interference increases
Solution Approach 1:
The patent dynamically controls transmission behavior based on communication mode and state. By implementing suspension mechanisms that activate when connection requests are detected, the system manages single-frequency usage dynamically, reducing interference without requiring multiple frequencies or increasing device complexity.

AI summary
A wireless communication terminal includes: a first communication unit that performs first-type wireless communication according to a first wireless communication method; a second communication unit that performs second-type wireless communication according to a second wireless communication method which is different than the first wireless communication method; and a control unit that controls the first communication unit and the second communication unit. In the state in which the communication mode is switched from the normal communication mode to a predetermined communication mode in which the first communication unit performs continuous transmission according to the first wireless communication method, when the second communication unit receives a connection request signal and establishes a communication connection by sending an acknowledgment signal as a permission for establishing a connection, the control unit controls the first communication unit to temporarily stop the continuous transmission performed according to the first wireless communication method.
