Abstract:
1. A method of optimizing reconnection of a point to point protocol link layer in a mobile device comprising the steps of: initializing a stabilization counter; monitoring whether the mobile device has entered a new zone from an original zone; after the monitoring step has determined that the mobile device has entered a new zone, incrementing said stabilization counter and determining whether said stabilization counter equals a maximum value, and if the stabilization counter equals the maximum value, then performing reconnection of the point to point protocol link layer to the new zone; starting a stabilization period; setting a stabilization timer for said stabilization period; checking whether the mobile device enters a different zone during the stabilization period; if the mobile device enters a different zone during the stabilization period, ending the stabilization period, resetting the stabilization timer and performing said incrementing, determining, starting, setting and checking steps; and if the stabilization period ends and the mobile device has not entered a different zone, determining whether the mobile device is in a new zone or said original zone, and if the mobile device is in said new zone, performing reconnection of the point to point protocol link layer to the new zone, otherwise if the mobile device is in said original zone, performing no reconnection of the point to point protocol link layer to the new zone; wherein the steps of the method are executed by the mobile device.
