WIRELESS NETWORK TRANSITIONING FOR MOBILE DEVICES
First Claim
1. A method, comprising:
- measuring a signal strength associated with a network at a first point in time;
calculating a predicted signal strength associated with the network at a second point in time based on the measurement;
determining whether a quality of the network is good based on the signal strength at the first point in time and the predicted signal strength at the second point in time;
determining whether the quality of the network is bad based on the signal strength at the first point in time and the predicted signal strength at the second point in time; and
determining whether to rove in or rove out of the network based on the determining whether the quality of the network is good and the determining whether the quality of the network is bad.

Abstract
A mobile device and method are provided for receiving a measured signal strength associated with a second network at a first point in time. The processor calculates a predicted signal strength associated with the second network at a second point in time based on the measured signal strength and makes a determination regarding whether the quality of the second network is good and a determination regarding whether the quality of the second network is bad based on the measured signal strength and the predicted signal strength. The processor determines whether to rove in or rove out of the second network based on the determination regarding whether the quality of the network is good and the determination regarding whether the quality of the network is bad.
