Wireless Network Switching Management for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals experience increased power consumption and reduced battery life when using both mobile phone and hot-spot wireless communication services simultaneously, due to the need to constantly check for high-speed service areas, leading to inefficient power usage and limited availability of high-speed internet.
Innovation Solution
A wireless communication system that includes a base station for low-speed wide-area service and an access point for high-speed limited-area service, which detects the presence of mobile terminals within the limited area and directs them to switch from low-speed to high-speed service via the low-speed service, reducing power consumption and notifying users of available high-speed services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile terminal uses both mobile phone service and hot-spot service simultaneously to check for high-speed service areas, then the service coverage is improved, but the power consumption is increased
Solution Approach 1:
The patent introduces a base station as an intermediary that receives notification messages from access points about terminal positions. The base station then notifies terminals via the mobile phone service about available hot-spot services, eliminating the need for terminals to continuously activate their hot-spot radio transceivers and reducing power consumption while maintaining service coverage
Solution Approach 2:
The system performs preliminary action by having access points continuously monitor and detect terminal positions, and base stations pre-process this information to generate notifications. This allows terminals to be informed in advance about available hot-spot services without needing to actively search, reducing their power consumption while ensuring service adaptability
2Measurement precision
If the mobile terminal activates the hot-spot radio transceiver to check for high-speed service areas, then the detection accuracy is improved, but the battery life is reduced
Solution Approach 1:
The base station acts as an intermediary that performs the detection function on behalf of the terminal. Access points detect terminal positions and communicate this to base stations, which then notify terminals. This eliminates the need for terminals to activate their hot-spot transceivers for detection, maintaining detection accuracy through the intermediary system while preserving battery life
Solution Approach 2:
The system implements self-service by having access points and base stations autonomously perform detection and notification functions. Access points automatically detect terminal positions within their coverage, and base stations automatically process and communicate this information to terminals, eliminating the need for terminal intervention and reducing power consumption

AI summary
A system and method for wireless network connection switching management is shown. The system notifies a mobile user that his portable terminal is within an area where it can be provided with local fast wireless communication service such as a hot-spot service versus using a low speed, but wide coverage wireless access network. Radio waves for communication transmitted by a mobile wireless terminal are received at a WWAN receiving system provided in a WLAN system. The radio waves are capable of communicating with a WWAN (Wireless Wide Area Network) system utilizing a third generation mobile phone network and a WLAN (Wireless Local Area Network) system providing a hot-spot service. Instructions are output to the terminal via the Internet and a base station of the WWAN system that the mobile terminal is within an AP service area of an access point of the WLAN system. The user may choose to switch wireless network access networks in order to achieve faster access to the Internet. Additionally, the method incorporates mechanisms to achieve reduced power consumption by the mobile terminal.
