ABSTRACT:
A system and method are described for determining when to exit an existing wireless communication coverage network. The method samples the device geographical position, determines a threshold boundary line, measures the position of each sample point with respect to the threshold boundary line, and, beginning at a predetermined initial value, maintains a running sum in response to measuring position. The existing coverage network is exited when the running sum is greater than or equal to a predetermined terminal value.
