Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication terminals face high power consumption when operating in wireless LAN mode, especially when not performing data communication, as they maintain a connected state with continuous beacon transmission, leading to increased energy usage.
Innovation Solution
The implementation of a dual-mode communication protocol system in wireless communication terminals, where the first communication device operates in a first mode and the third communication device in a second mode, allowing for efficient data communication only when necessary, with processors managing the transition between modes to minimize power consumption based on data transfer conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless LAN maintains a connected state with continuous beacon transmission, then the connection stability is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic switching between two operational modes: a connected mode with continuous beacon transmission for stable connections, and a disconnected mode with stopped beacon transmission for reduced power consumption. The system dynamically transitions between these modes based on whether data communication is active, allowing it to adapt its behavior to current operational needs and resolve the contradiction between connection stability and power consumption.
Solution Approach 2:
The patent employs periodic beacon transmission only when necessary (during data communication), rather than continuous periodic transmission. By stopping beacon transmission when no data communication is occurring and resuming only when needed, the system eliminates unnecessary periodic actions that consume power while maintaining connection stability only during active communication periods.
2Use of energy by moving object
If the wireless LAN is disconnected to reduce power consumption, then the energy usage decreases, but the connection availability deteriorates
Solution Approach 1:
The system dynamically adjusts its operational state based on real-time communication needs. When data communication is not active, the system disconnects the wireless LAN to save power. When data communication becomes necessary, the system automatically reconnects, ensuring connection availability is maintained precisely when needed while minimizing power consumption during idle periods.
Solution Approach 2:
The patent changes the operational parameters of the wireless LAN based on communication activity. The system transitions the wireless LAN between connected and disconnected states, effectively changing the connection parameter from 'connected' to 'disconnected' when appropriate. This parameter change allows the system to optimize power consumption without permanently sacrificing connection availability.

AI summary
In a wireless communication terminal, a processor transmits instruction information to a fourth communication device of an external terminal by a second communication device when a first condition and a second condition are satisfied. The instruction information is information for instructing the external terminal to transmit a connection request for the wireless communication terminal. The first condition is a condition that a second communication connection is established between the second communication device and the fourth communication device. The second condition is a condition that the first communication device is operating in a first mode. If the connection request has been received after transmission of the instruction information, the processor establishes a first communication connection with a third communication device of the external terminal by the first communication device.
