ABSTRACT:
In cellular communication systems, hand-offs are performed to maintain links as subscriber units (110) and cells (420, 450) move relative to each other. The hand-off process is improved by using a pre-stored time-based cell map (400) and precise geo-location data. This information is used to set a hand-off timer for deterministically initiating the hand-off process in the current cell (500). The timer diminishes the amount of power monitoring which is required in the hand-off initiation process. This capability is especially important in satellite communication systems with fast moving cells and sharp boundaries.
