Claim:
A method of maintaining data connectivity of a mobile station in a network, comprising: establishing a data link between the mobile station and a first zone; entering, by the mobile station, a second zone while retaining the data link with the first zone; upon detecting that the mobile station has entered the second zone, initiating, by the mobile station, a timer-based preset period of time during which connecting of the data link to the second zone will be postponed; postponing connecting the data link to the second zone until after the preset period of time ends; and when the preset period of time ends if the mobile station is still in the second zone, then connecting the data link to the second zone; detecting that the mobile station has entered a third zone from the second zone during the preset period of time; in response to detecting that the mobile station has entered the third zone, re-initiating the timer-based preset period of time; after the preset period of time ends, determining if the mobile station is in the third zone; and if the mobile station is in the third zone after the preset period of time ends, then connecting the data link to the third zone.
