Base Station Wireless Wake-on-LAN Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wake-on-LAN technologies for remotely turning on devices in wireless networks face inefficiencies due to the need for broadcasting start instructions, which can lead to unnecessary power consumption and network traffic, and lack precise control over device identification and authorization.
Innovation Solution
A base station apparatus with a wireless receiving unit for identifying terminal devices, a storage unit for managing identification information, and a distribution unit for wirelessly distributing start instructions to specific devices, using ultraweak radio waves to reduce power consumption and network impact, while ensuring only authorized devices are started.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If broadcasting is used to deliver magic packets in wireless networks, then all terminal devices can receive the start instruction, but unnecessary power consumption and network traffic occur
Solution Approach 1:
The patent extracts the start instruction from the broadcast magic packet and delivers it individually to each terminal device through unicast communication. The base station receives the magic packet, extracts the target terminal's identification information, and sends the start instruction only to that specific terminal, eliminating unnecessary reception by other terminals and reducing overall power consumption and network traffic.
Solution Approach 2:
The base station acts as an intermediary between the external communication device and terminal devices. It receives the broadcast magic packet, processes the identification information, and selectively forwards start instructions to authorized terminals. This intermediary role enables precise control over which terminals receive startup commands, preventing unnecessary power consumption across the entire network.
2Ease of operation
If broadcasting is used to deliver start instructions, then all terminal devices receive the instruction, but precise control over device identification and authorization is lost
Solution Approach 1:
The patent extracts the target terminal's identification information from the broadcast magic packet at the base station. Instead of relying on all terminals to self-identify from the broadcast, the base station explicitly identifies the target terminal and sends personalized start instructions, ensuring precise device identification and authorization control.
3Adaptability or versatility
If magic packets are broadcast to all terminal devices, then any terminal can be started, but network traffic increases unnecessarily
Solution Approach 1:
The patent extracts and processes the target terminal's identification from the broadcast magic packet at the base station, then sends individualized start instructions via unicast. This approach maintains the versatility of remote startup while dramatically reducing network traffic by eliminating redundant transmissions to unauthorized terminals.
Solution Approach 2:
The base station serves as an intermediary that filters and directs start instructions selectively. It receives the broadcast magic packet, identifies the target terminal through its identification information, and forwards the start instruction only to the authorized terminal, thereby reducing unnecessary network traffic while preserving remote startup functionality.

AI summary
A base station apparatus includes a wireless receiving unit wirelessly receiving identification information on a terminal apparatus located in the vicinity of the base station apparatus; a storage unit storing the identification information received by the wireless receiving unit; a request receiving unit receiving, from a communication apparatus, a start request containing identification information regarding a terminal apparatus to be started; a determination unit determining whether the identification information contained in the start request received by the request receiving unit having been stored in the storage unit; and a distribution unit wirelessly distributing a start instruction to start the terminal apparatus indicated by the identification information upon the determination unit determining the identification information having been stored in the storage unit.
