WiFi Router Wake-Up via Bluetooth Auto-Scan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for waking up a WiFi network on a router require user intervention, degrading the interaction experience and increasing power consumption, as users need to manually enable Bluetooth and scan for available networks to reactivate the WiFi connection.
Innovation Solution
A method where a terminal automatically detects if the WiFi network is disabled, enables Bluetooth, scans for available networks, matches the MAC address or unique identifier of the router, and establishes a Bluetooth connection to wake up the router, thereby reactivating the WiFi network without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the router automatically disables the WiFi network to reduce power consumption, then the working duration is improved, but the ease of operation deteriorates because users need to manually enable Bluetooth and scan for networks to reactivate WiFi
Solution Approach 1:
The terminal performs self-service by automatically detecting the disabled WiFi network state, enabling Bluetooth, scanning for networks, matching MAC addresses, and establishing connections to wake up the router without requiring manual user intervention for each step
Solution Approach 2:
The terminal performs preliminary actions by pre-configuring the automatic wake-up process, including storing historical connection information with MAC addresses and preparing the Bluetooth function to be automatically enabled when WiFi is disabled
2Use of energy by stationary object
If the router disables the WiFi network to reduce power consumption, then the use of energy is improved, but the ease of operation deteriorates because users need to manually perform multiple operations to reactivate WiFi
Solution Approach 1:
The terminal automatically performs the entire wake-up process including detecting WiFi status, enabling Bluetooth, scanning networks, matching MAC addresses, and establishing connections without requiring manual user operations
Solution Approach 2:
The patent merges multiple operations (WiFi detection, Bluetooth enabling, network scanning, MAC address matching, and connection establishment) into a single automated wake-up process that executes sequentially without user intervention
3Ease of operation
If the terminal automatically performs Bluetooth scanning and connection to wake up WiFi, then the ease of operation is improved, but the use of energy deteriorates due to additional power consumption from Bluetooth operations
Solution Approach 1:
The terminal performs preliminary Bluetooth scanning only when necessary (when WiFi is disabled and needs to be woken up), rather than continuously scanning, thereby minimizing energy consumption while maintaining automatic operation capability
Solution Approach 2:
The system uses periodic action by enabling Bluetooth and performing scanning only at specific moments when the WiFi network needs to be activated, rather than maintaining continuous operation, thus balancing ease of use with energy efficiency

AI summary
Embodiments of the present invention disclose a method for waking up a Wireless Fidelity network, and a terminal, so as to automatically wake up a WiFi network on a router side when a user needs to use the WiFi network in a case in which the WiFi network is disabled, so as to reduce user operations and improve user experience. The method in the embodiments of the present invention includes: when it is determined that a terminal needs to connect to a particular WiFi network, detecting whether a particular router has enabled the particular WiFi network; when it is determined that the particular WiFi network is not enabled, enabling, by the terminal, a BT function, and scanning and obtaining, according to information about the particular WiFi network recorded in historical connection information, a BT identifier corresponding to the particular router; and establishing a BT connection to the particular router according to the BT identifier corresponding to the particular router, and waking up the particular router by means of the BT connection, so that the particular router enables the particular WiFi network.
