Abstract
A system and method for executing network acquisition employ a triggered scan for network acquisition regardless of the recorded optimal nature of the current network. In general, when one or more predefined conditions occur, a network scan is initiated to identify another network, if any, that is more optimal than the current network. Example trigger conditions include failed registration attempts, exceeding a predetermined distance threshold, entry to or exit from a pre-determined region, excess CDMA Chip delay, and others. Triggers may be used singly or in Boolean combinations. In this way, network scanning occurs when it may be beneficial, but will not be initiated too frequently or in situations where connectivity may not actually be suboptimal. This triggered scan provides improved connectivity, and can allow the device to make and receive calls in locations where it would otherwise not have been possible.
