Mobile Terminal Network Connection Control via Traffic Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication systems face resource shortages and inefficiencies due to mobile terminals connecting to wireless networks that are not actively connected to the Internet, leading to prolonged standby times and disrupted internet access.
Innovation Solution
A network connection control method for mobile terminals that determines whether actual traffic is received from the connected wireless network, releasing the connection if no traffic is detected and switching to a cellular network or another wireless network if necessary, ensuring continuous internet access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the mobile terminal connects to the wireless network with the highest received signal strength, then the connection speed and signal quality are improved, but the terminal may connect to an AP that is not connected to the Internet, resulting in no actual internet access
Solution Approach 1:
The patent implements a feedback mechanism where the mobile terminal monitors whether received data packets are actual internet traffic or not. If no internet traffic is detected after connection, the terminal releases the connection and attempts to reconnect to a different AP. This feedback loop resolves the contradiction by ensuring the terminal only maintains connections that provide actual internet access, while still preferring high-signal APs when they do provide access.
Solution Approach 2:
The patent performs preliminary actions by checking whether an AP is connected to the Internet before establishing a stable connection. The terminal sends a probe request to discover APs and checks their connectivity status in advance. This preliminary verification prevents the terminal from connecting to non-internet APs, resolving the reliability issue while maintaining the ability to connect to high-signal APs that do provide internet access.
2Stability of the object's composition
If the mobile terminal maintains connection to a wireless network without actual traffic, then the connection is kept established, but the terminal remains in standby mode unnecessarily for long periods, wasting resources
Solution Approach 1:
The patent uses feedback to monitor actual traffic reception continuously. When no internet traffic is detected for a predetermined period, the system determines the AP is not providing actual internet access and releases the connection. This feedback-based monitoring prevents the terminal from maintaining useless connections, thereby reducing energy consumption while preserving connection stability for APs that do provide actual internet access.
Solution Approach 2:
The patent discards connections to APs that are not providing actual internet access after a predetermined monitoring period. The terminal releases the connection and may attempt to reconnect to a different AP. This discarding mechanism eliminates wasteful energy consumption from maintaining non-functional connections, while the recovering capability allows the terminal to find alternative functional APs.
3Productivity
If the connection preference policy is based solely on received signal strength, then the selection process is simple and fast, but it cannot distinguish between active and idle networks, leading to inefficient resource utilization
Solution Approach 1:
The patent makes the connection preference policy dynamic by adding a traffic monitoring dimension. Instead of a static signal-strength-based policy, the system dynamically adjusts connection decisions based on actual traffic reception. The terminal monitors whether received data is actual internet traffic and uses this information to dynamically adjust connection preferences, releasing idle connections and maintaining active ones. This dynamic approach improves resource utilization while maintaining efficient connection selection.
Solution Approach 2:
The patent performs preliminary actions by checking AP connectivity status before finalizing connection decisions. The terminal sends probe requests to discover APs and checks their internet connectivity in advance. This preliminary verification allows the connection preference policy to distinguish between active and idle networks, improving resource utilization by preventing connections to non-functional APs while maintaining selection efficiency.

AI summary
A network connection control method and apparatus of a mobile terminal maintains or releases connection to a wireless network based on the existence of downlink traffic from the wireless network. The method preferably includes connecting to a wireless network transmitting a signal greater than a predetermined value in strength when an Internet access request is detected; requesting the connected wireless network for traffic; determining whether the traffic is received from the connected wireless network; and releasing the connection to the wireless network by determining the wireless network as an idle wireless network when no traffic is received. The determination as to whether to maintain or release the connection to the currently connected WLAN based on whether actual traffic is received from the WLAN. When the mobile terminal is connected to an Access Point not coupled to the Internet, the mobile terminal immediately switches the connection to a cellular network.
