ABSTRACT:
A wireless device uses position-indicating data to determine its location in relation to multi-layered wireless networks that the device may see concurrently. If location information is available, the device employs a user-defined priority table to select the order of user-contracted available networks. If location information is unavailable, the device employs a technology learning table to automatically adapt CAI protocol options (e.g., GSM, cdma2000, IS-136, IEEE 802.11x, etc.) to search for an available network. Information is gathered and stored in databases within the device to allow automatic adaptation to multiple wireless networks. The device provides unique access to each wireless network with which a user has contracted, without the intervention of any “anchor” network. This allows the device to obtain network service no matter what network it is traveling through and allows the user to traverse multiple wireless networks with seamless access to multiple applications and services provided by those networks.
