Abstract:
1. A method, comprising: detecting, by a mobile node, information in a beacon of a first signal received from an access node with which the mobile node is connected; detecting, by the mobile node, a signal strength from a second signal received from the access node with which the mobile node is connected; upon indication by the border information in the beacon that the mobile node is in a non-border-region, and upon determination that the signal strength is below a predetermined threshold, the mobile node waiting for a predefined time; after the predefined time has passed, detecting, by the mobile node, a signal strength from a third signal received from the access node with which the mobile node is connected; and upon determination that the signal strength is still below a predetermined threshold, initiating, by the mobile node, handoff from a first technology network to a second technology network.
