Advanced network characterization and migration
First Claim
1. A method for switching a mobile device from a first network to a second network, the method comprising:
- communicating with the mobile device via the first network;
detecting the second network, wherein the first network is a cellular telephone network and the second network is a WiFi network;
applying a hand-off policy filter to the second network;
determining, based on application of the hand-off policy filter, that the mobile device should connect to the second network, wherein the hand-off policy filter includes a hand-off grade for the second network, wherein the hand-off grade is alternately unstable, short lived session expected and stable, wherein the hand-off grade is based on information received from an access point and calculations on the information indicating signal strength of the access point and distance between the access point and the mobile device, wherein the hand-off grade is a function ofdetermining, based on signal data, movement of the mobile device relative to one or more access points of the second network;
determining that one or more signals of the second network are above a dwell threshold level for reliable wireless connectivity;
determining data transfer costs of a network connection for the first network compared to the data transfer costs of a network connection for the second network; and
connecting, based upon the hand-off grade, the mobile device to the second network.

Abstract
In some embodiments, a method includes scanning for wireless networks, where scanning includes collecting network information indicating properties of the wireless networks. The method can include analyzing the network information to determine signal data indicating signal qualities for the wireless networks. The method can include characterizing, based on the signal data, one or more wireless networks as being suitable for connection by the mobile device, where the characterizing includes determining, based on the signal data, movement of the mobile relative to one or more access points of the wireless networks. The method can include determining that one or more signals of the wireless networks are above a dwell threshold level for reliable wireless connectivity. The method can include determining that one or more signals has been dropped, and connecting to the mobile device to one of the one or more wireless networks that are suitable for connection.
