IP NETWORK INFORMATION DATABASE IN MOBILE DEVICES FOR USE WITH MEDIA INDEPENDENT INFORMATION SERVER

摘要

A mobile device receives wireless network information from a MIIS (Media Independent Information Server), and builds its own database of existing networks with their associated characteristics, appropriately mapped with GPS (Global Positioning Satellite) coordinates or other appropriate form of geographical location identifying information. Consequently, the mobile device becomes "smart" over time through the learning process of first attempting to utilize its own developed database and, only if such database information falls short, making a remote query to a MIIS to get required information for session continuity and performing handovers. The mobile device may store the information received from the MIIS in its own local database together with a time-stamp. Each time the mobile device needs to get updated or new information, it sends a request to the MIIS along with the time-stamp appended to the request. In this way, the mobile device is sent only the information that it does not already have stored in its database
